The main result of this paper is a new design approach is proposed of realizable feedforward and feedback optimal control law for a linear time invariant system with sinusoidal disturbances. The algorithm of solving the optimal control law is given. It is shown that the control law is easily realized and is robust with respect to errors produced by the external sinusoidal disturbances through simulation results. | 唐功友 | 2001 | High Technology Letters2001，7，4： | 38 |
| 2 | Petawatt and exawatt class lasers worldwide显示文摘In the 2015 review paper‘Petawatt Class Lasers Worldwide’a comprehensive overview of the current status of highpower facilities of>200 TW was presented.This was largely based on facility specifications,with some description of their uses,for instance in fundamental ultra-high-intensity interactions,secondary source generation,and inertial confinement fusion(ICF).With the 2018 Nobel Prize in Physics being awarded to Professors Donna Strickland and Gerard Mourou for the development of the technique of chirped pulse amplification(CPA),which made these lasers possible,we celebrate by providing a comprehensive update of the current status of ultra-high-power lasers and demonstrate how the technology has developed.We are now in the era of multi-petawatt facilities coming online,with 100 PW lasers being proposed and even under construction.In addition to this there is a pull towards development of industrial and multi-disciplinary applications,which demands much higher repetition rates,delivering high-average powers with higher efficiencies and the use of alternative wavelengths:mid-IR facilities.So apart from a comprehensive update of the current global status,we want to look at what technologies are to be deployed to get to these new regimes,and some of the critical issues facing their development. | Colin N.Danson Constantin Haefner Jake Bromage Thomas Butcher Jean-Christophe FChanteloup Enam A.Chowdhury Almantas Galvanauskas Leonida A.Gizzi Joachim Hein David I.Hillier Nicholas W.Hopps Yoshiaki Kato Efim A.Khazanov Ryosuke Kodama Georg Korn Ruxin Li Yutong Li Jens Limpert Jingui Ma Chang Hee Nam David Neely Dimitrios Papadopoulos Rory R.Penman Liejia Qian Jorge J.Rocca andrey A.Shaykin Craig W.Siders Christopher Spindloe Sándor Szatmári Raoul M.G.M.Trines Jianqiang Zhu Ping Zhu Jonathan D.Zuegel | 2019 | High Power Laser Science and Engineering2019，7，3： | 33 |
| 3 | Improvement of the Mirror Extending in Empirical Mode Decomposition Method and the Technology for Eliminating Frequency Mixing显示文摘The mirror extending approach proposed by Zhao and Huang in EMD method is improved in this paper. Mirror extending manner of data is kept unchanged, but the approach for determining envelopes is changed. When the end of data is obviously not extremum, the envelope is determined by the first inner extremum and the image value in the mirror, ignoring the value on the end. This improvement eliminates the frequency compression near the end and decreases the error. Meanwhile, tridiagonal equations are used and the calculation speed is much increased. The temporal process curve is more important in reflecting the real physical process and comparable with other phenomena. Frequency mixing in IMFs makes it impossible. A high frequency reconstruction (HFR) approach is proposed to eliminate common frequency mixing and reconstruct an IMF with all high frequency portions. By this approach, the IMFs without frequency mixing are obtained to express significative processes. The high frequency information restored in high frequency IMF can be extracted by general spectrum method. After obtaining IMFs by EMD method, some of the theoretical and technological issues still exist when using the IMFs. The consistency of IMFs with real physical process is discussed in detail. By virtue of the approach proposed in this paper, the EMD method can be widely used in various fields. | 赵进平 | 2002 | High Technology Letters2002，8，3： | 30 |
| 4 | Biological activities of a neutral water-soluble agar polysaccharide prepared by agarase degradation显示文摘Depolymerization of agar was performed using agarase, which was extracted from the cell-free medium of a culture of marine bacterial Alteromonas sp. nov. SY 37-12. After ethanol fractionation and lyophilization, the water-soluble agar polysaccharide (WSAP3) was collected. The anti-tumor activity of the product was determined by using Sarcoma 180 tumor in mouse. The tumor inhibition rate of WSAP3 reached 48.7% at a dose of 64mg kg-1 after 15 days treatment. WSAP3 enhanced the activities of superoxide dismutase and catalase, which suggests that WSAP3 was effective in promoting the antioxidation ability and eliminating danger from free radicals. The result of flow cytometry showed that the WSAP3 had no activities of cell cycle inhibition or apoptosis-inducing activities. The anti-oxidation of WSAP3 was further confirmed by test in vitro, which might play an important role in anti-tumor activity. The immunological regulation of WSAP3, especially its effect on the phagocytosis ratio and phagocytosis index of macrophage was also assayed in test in vivo. | 王静雪 Mou Haijin Jiang Xiaolu Guan Huashi | 2005 | High Technology Letters2005，11，4： | 24 |
| 5 | Detection of Grass Carp Hemorrhage Virus (GCHV) from Vietnam and Comparison with GCHV Strain from China显示文摘Grass carp plays an important role in small-scale aquaculture in Vietnam. However, a severe disease, known in Vietnam as 'Red Spot Disease', is causing significant economic loss in grass carp aquaculture. In this study, the tissue samples isolated from the grass carp with Red Spot Disease in Vietnam are investigated and comparied with the control GCHV isolated in China by experimental infection, culture cell infection, serological cross reactivity, and RT-PCR amplification. Infected grass carp exhibits hemorrhage symptoms about 5 days after experimental injection with GCHV-V (Vietnam) strain. The symptoms and lethality induced by the GCHV-V strain are identical to that induced by the Chinese GCHV-9014 strain. The Chinese GCHV-873 strain induces typical cytopathogenic effects in 4 cell lines, such as CIK, CAB, FHM and GCO, from the 6 fish cell lines examined. No cytopathogenic effects are observed in all the 6 examined cell lines, including CAB, FHM, CIK, EPC, CCO and GCO, infected by the GCHV-V strain and GCHV-9014 strain. Immunodiffusion assays demonstrate an obvious cross-reactivity among three GCHV strains. Precipitin lines are clearly observed not only between the anti-GCHV-873 serum and the two strains GCHV-873 and GCHV-9014, but also between the anti-GCHV-873 serum and the GCHV-V strain. GCHV can be detected by immunodiffusion assays after three generations of blind propagations in the cell lines inoculated by GCHV-V strain. This implicates that GCHV-V viruses have been replicated and amplified despite there being no cytopathogenic effects observed in these examined cell lines. Three genome segments of GCHV, including S8, S9 and S10, are amplified by three sets of PCR primers designed according to the segment sequences published recently. The Q8fp and Q8rp primer set specific for genome segment S8 amplifies a 955 bp fragment from the extracted sample of diseased fish with Red Spot Disease, and the fragment size is identical to that amplified by the same primer set from control GCHV-873 strain. Simultaneously, the Q9fp and Q9rp primer set specific for genome segment S9 generates a same 635 bp product, and the Q10fp and Q10rp primer set specific for genome segment S10 produces a same 697 bp fragment from both template samples of diseased fish with Red Spot Disease and control GCHV-873 strain. The RT-PCR amplification and corresponding size comparison data indicate that the three GCHV-V genome segments extracted from the diseased grass carp with Red Spot Disease in Vietnam should be identical to that in control GCHV-873 strain from China. The data confirm that the causative agent of grass carp Red Spot Disease in Vietnam is a virus, and the virus is closely similar to GCHV strain in China. | 张奇亚 Ruan Hongmei Li Zhenqiu Zhang Jing Gui Jianfang | 2003 | High Technology Letters2003，9，2： | 20 |
| 6 | Petawatt class lasers worldwide显示文摘The use of ultra-high intensity laser beams to achieve extreme material states in the laboratory has become almost routine with the development of the petawatt laser. Petawatt class lasers have been constructed for specific research activities,including particle acceleration, inertial confinement fusion and radiation therapy, and for secondary source generation(x-rays, electrons, protons, neutrons and ions). They are also now routinely coupled, and synchronized, to other large scale facilities including megajoule scale lasers, ion and electron accelerators, x-ray sources and z-pinches. The authors of this paper have tried to compile a comprehensive overview of the current status of petawatt class lasers worldwide.The definition of ‘petawatt class' in this context is a laser that delivers >200 TW. | Colin Danson David Hillier Nicholas Hopps David Neely | 2015 | High Power Laser Science and Engineering2015，3，1： | 16 |

| 9 | The Synthesis of a Stewart Platform for a Specific Workspace with a Genetic Algorithm显示文摘The synthesis problem of a 6-SPS Stewart platform with semi-regular hexagons is studied in this paper. We present a genetic algorithm approach to synthesize a Stewart platform whose workspace must include a desired workspace with orienting capabilities in a given 3D region. Based on the observation that the constant orientation workspace gets smaller as the given orientations increase, a simple method is presented to describe the workspace with orienting capabilities, which need only search the constant orientation workspaces with the eight sets of extremal orientations of given 3D region and use their common part.To verify the method, a numerical example is given. The GA is used to optimize architectural parameters and obtain a compact manipulator. The method is applied to synthesize a Stewart platform whose workspace must include a prescribed cylinder with orienting capabilities. | 陈学生 Chen Zaili Xie Tiao | 2004 | High Technology Letters2004，10，1： | 11 |
| 10 | Occurrence, Development and Histochemical Characteristics of Lymphocystis in Cultured Japanese Flounder (Paralichthys olivaceus)显示文摘Occurrence and development of lymphocystis cells in flounder Paralichthys olivaceus, and some histochemical features are studied using light and electron microscopy and histochemical methods. Fibroblasts engulf virus particles forming phagocytosis vacuole in the cytoplasm. The infected cells proliferate and turn round and hypertrophied; basophilic inclusion bodies, Feulgen-positive, are present in the cytoplasm, and a hyaline capsule, containing acid ploysaccharide and protein, appears outside cell membrane. The mature lymphocystis cells possess numerous virus particles (200~220nm in diameter with a central core 120~140nm) and high electron-dense inclusions with budding virions at the surface in the cytoplasm, and show margination of chromatin. Moderate electron density particles (70~80nm in diameter) fill out perinuclear cisterna and arrange in crystalloid arrays in nucleus, liberated into the cytoplasm by rupture of nuclear membrane. No virus particles are observed in nucleus. Therefore, inclusion bodies are the sites of virus assembly and maturity, while replication processes of lymphocystis virus are involved in both nuclear and cytoplasmic phases. Besides, strongly basophilic link-like structures are present between adjacent cells or through connective tissue, and virus particles are observed in somewhere of the capsule, thus where may be the spread route of virus from one cell to another or to the environment. The senile lymphocystis cells release virus by the rupture of cells. | 绳秀珍 Zhan Wenbin | 2004 | High Technology Letters2004，10，2： | 10 |
| 11 | Phenotypic and genetic variation between two populations of the Chinese yellow pond turtle, Mauremys mutica (Cantor, 1842)显示文摘Mauremys mutica(Cantor,1842)is an endangered species in China.Main phenotypic variations inbody color,body weight,body shape,clutch size,egg size,and hatchling size were revealed betweenthe southern and northern populations.Both populations have the phenomenon of'larger male'sexualsize dimorphism(SSD),especially in the southern population.Furthermore,genetic variations betweenthe two populations were analyzed by RAPD band patterns of 30 random individuals in each population.The average genetic distance was 0.299±0.108 among the samples of two populations.The average ge-netic distance between southern and northern populations was 0.305±0.046.Cluster analysis indicatedthat all the individuals from the southern and northern populations were clustered among themselves toform two distinct clades.A total of 20 population-specific RAPD fragments were scored from 16 primers,and could be used as RAPD markers for distinguishing the southern and the northern population.Basedon the nucleotide sequences of two RAPD markers,two pairs of SCAR primers(SC1-S and SC2-S)weredesigned,which could be used as SCAR markers for the southern population.According to the significantphenotypic and genetic variations,we suggested that the northern population and southern populationmight be considered as two separate taxa,the'northern taxon'and the'southern taxon',and the con-servation should be respectively conducted on the two taxa. | 朱新平 Zhou Li Chen Yongle Du Hejun Gui Jianfang | 2008 | High Technology Letters2008，14，1： | 10 |
| 12 | Deep-learning-based phase control method for tiled aperture coherent beam combining systems显示文摘We incorporate deep learning(DL)into tiled aperture coherent beam combining(CBC)systems for the first time,to the best of our knowledge.By using a well-trained convolutional neural network DL model,which has been constructed at a non-focal-plane to avoid the data collision problem,the relative phase of each beamlet could be accurately estimated,and then the phase error in the CBC system could be compensated directly by a servo phase control system.The feasibility and extensibility of the phase control method have been demonstrated by simulating the coherent combining of different hexagonal arrays.This DL-based phase control method offers a new way of eliminating dynamic phase noise in tiled aperture CBC systems,and it could provide a valuable reference on alleviating the long-standing problem that the phase control bandwidth decreases as the number of array elements increases. | Tianyue Hou Yi An Qi Chang Pengfei Ma Jun Li Dong Zhi Liangjin Huang Rongtao Su Jian Wu Yanxing Ma Pu Zhou | 2019 | High Power Laser Science and Engineering2019，7，4： | 10 |

| 14 | Genetic Diversity in Populations of Sepiella maindroni Using 16S rRNA Gene Sequence Analysis显示文摘Part of the 16S rRNA gene is amplified with PCR and sequenced for 5 populations of common Chinese cuttlefish Sepiella maindroni: three from the South China Sea, one from East China Sea and one from Japan. The result shows that a total of 5 nucleotide positions are found to have gaps or insertions of base pairs among these individuals, and 13 positions are examined to be variable in all the sequences, which range from 494 to 509 base pairs. All of the individuals are grouped into 7 haplotypes (h1-h7). No marked genetic difference is observed among those populations. All of the individuals from Nagasaki belong to h1 and the h3 haplotype is found only in the coastal waters of China. AG transition in Nucleotide 255 is suggested to be taken as a kind of genetic marker to identify the populations distributed in East-South China Sea and the Nagasaki waters of Japan. | 郑小东 WANG Rucai Xiao Shu Yu Ruihai Yang Jianmin | 2003 | High Technology Letters2003，9，1： | 10 |
| 15 | High power all-fiberized and narrow-bandwidth MOPA system by tandem pumping strategy for thermally induced mode instability suppression显示文摘An all-fiberized and narrow-bandwidth master oscillator power amplification(MOPA) system with record output power of 4 kW level and slope efficiency of 78% is demonstrated. Tandem pumping strategy is tentatively introduced into the narrow-bandwidth MOPA system for thermally induced mode instability(TMI) suppression. The stimulated Brillouin scattering(SBS) effect is balanced by simply using one-stage phase modulation technique. With different phase modulation signals, SBS limited output powers of 336 W, 1.2 kW and 3.94 kW are respectively achieved with spectral bandwidths accounting for 90% power of ~0.025, 0.17 and ~0.89 nm. Compared with our previous 976 nm pumping system, TMI threshold is overall boosted to be >5 times in which tandem pumping increases the TMI threshold of >3times. The beam quality(M~2 factor) of the output laser is well within 1.5 below the TMI threshold while it is ultimately saturated to be 1.86 with the influence of TMI at maximal output power. Except for SBS and TMI, stimulated Raman scattering(SRS) effect will be another challenge for further power scaling. In such a high power MOPA system, multidetrimental effects(SBS, SRS and TMI) will coexist and may be mutual-coupled, which could provide a well platform for further comprehensively investigating and optimizing the high power, narrow-bandwidth fiber amplifiers. | Pengfei Ma Hu Xiao Daren Meng Wei Liu Rumao Tao Jinyong Leng Yanxing Ma Rongtao Su Pu Zhou Zejin Liu | 2018 | High Power Laser Science and Engineering2018，6，4： | 9 |

| 17 | All-fiberized and narrow-linewidth 5 kW power-level fiber amplifier based on a bidirectional pumping configuration显示文摘In this paper,an all-fiberized and narrow-linewidth 5 kW power-level fiber amplifier is presented.The laser is achieved based on the master oscillator power amplification configuration,in which the phase-modulated single-frequency laser is applied as the seed laser and a bidirectional pumping configuration is applied in the power amplifier.The stimulated Brillouin scattering,stimulated Raman scattering,and transverse mode instability effects are all effectively suppressed in the experiment.Consequently,the output power is scaled up to 4.92 kW with a slope efficiency of as high as approximately 80%.The 3-dB spectral width is about 0.59 nm,and the beam quality is measured to be M^(2)~1.22 at maximum output power.Furthermore,we have also conducted a detailed spectral analysis on the spectral width of the signal laser,which reveals that the spectral wing broadening phenomenon could lead to the obvious decrease of the spectral purity at certain output power.Overall,this work could provide a reference for obtaining and optimizing high-power narrow-linewidth fiber lasers. | Pengfei Ma Hu Xiao Wei Liu Hanwei Zhang Xiaolin Wang Jinyong Leng Pu Zhou | 2021 | High Power Laser Science and Engineering2021，9，3： | 9 |
| 18 | Fabrication of kW-level chirped and tilted fiber Bragg gratings and filtering of stimulated Raman scattering in high-power CW oscillators显示文摘Suppression of stimulated Raman scattering(SRS)by means of chirped and tilted fiber Bragg gratings(CTFBGs)has become a key topic.However,research on high-power systems is still lacking due to two problems.Firstly,after the inscription,there are a large number of hydroxyl compounds and hydrogen molecules in CTFBGs that cause significant heating due to their strong infrared absorption.Secondly,CTFBGs can couple Stokes light from the core to the cladding and the coating,which causes serious heating in the coating of the CTFBG.Aimed at overcoming these bottlenecks,a process that combines constant-low-temperature and variable-high-temperature annealing is used to reduce the thermal slope of the CTFBG.Also,a segmented-corrosion cladding power stripping technology is used on the CTFBG to remove the Stokes light which is coupled to the cladding,which solves the problem of overheating in the coating of the CTFBG.Thereby,a CTFBG with both a kilowatt-level power-carrying load and the ability to suppress SRS in a fiber laser has been developed.Further,we establish a kW-level CW oscillator to test the CTFBG.Experimental results demonstrate that the power-carrying load of the CTFBG is close to 1 kW,the thermal slope is lower than 0.015 ℃/W,and the SRS suppression ratio is nearly 23 dB. | Kerong Jiao Jian Shu Hua Shen Zhiwen Guan Feiyan Yang Rihong Zhu | 2019 | High Power Laser Science and Engineering2019，7，2： | 9 |

| 20 | Progress in and prospects for electrical insulating materials显示文摘The performance of electrical equipment and devices is determined to a great extent by the properties of their insulating materials.In power systems and electrical devices,insulating materials have to work in extreme circumstances that can include high temperature differences,intense radiation,and strong electric fields.Such conditions demand high-quality insulating materials with superior electrical,thermal,and mechanical properties as well as resilience to other environmental stresses.This study focuses on advances in insulating materials since the early 20th century and reviews the many developments in their properties and applications,including electric breakdown strength,thermal conductivity,temperature resistance,corona resistance,and specific energy storage in dielectrics.Some research progress on other properties is also covered,such as non-linearity and radiation resistance.Investigations into the properties of insulating materials can greatly assist in understanding their interface effects and composite structures,which in turn is helpful for discovering methods to improve the performance of electrical devices.Future directions for research are proposed to guide new investigations and support the development of even better insulating materials. | Shengtao Li Shihu Yu Yang Feng | 2016 | High Voltage2016，1，3： | 8 |
