| 1 | Effects of continuously regenerating diesel particulate filters on regulated emissions and number-size distribution of particles emitted from a diesel engine显示文摘The effects of continuously regenerating diesel particulate filter (CRDPF) systems on regulated gaseous emissions, and number-size distribution and mass of particles emanated from a diesel engine have been investigated in this study. Two CRDPF units (CRDPF-1 and CRDPF-2) with different specifications were separately retrofitted to the engine running with European steady-state cycle (ESC). An electrical low pressure impactor (ELPI) was used for particle number-size distribution measurement and mass estimation. The conversion/reduction rate (R CR ) of hydrocarbons (HC) and carbon monoxide (CO) across CRDPF-1 was 83% and 96.3%, respectively. Similarly, the R CR of HC and CO and across CRDPF-2 was 91.8% and 99.1%, respectively. The number concentration of particles and their concentration peaks; nuclei mode, accumulation mode and total particles; and particle mass were highly reduced with the CRDPF units. The nuclei mode particles at downstream of CRDPF-1 and CRDPF-2 decreased by 99.9% to 100% and 97.8% to 99.8% respectively; and the particle mass reduced by 73% to 92.2% and 35.3% to 72.4%, respectively, depending on the engine conditions. In addition, nuclei mode particles increased with the increasing of engine speed due to the heterogeneous nucleation initiated by the higher exhaust temperature, while accumulation mode particles were higher at higher loads due to the decrease in the air-to-fuel ratio (A/F) at higher loads. | Zhihua Liu Asad Naeem Shah Yunshan Ge Yan Ding, Jianwei Tan Lei Jiang Linxiao Yu Wei Zhao Chu Wang Tao Zeng | 2011 | Journal of Environmental Sciences2011，23，5： | 15 |
| 2 | Monovalent cation perm-selective membranes(MCPMs)'New developments and perspectives显示文摘As one of the most typical and promising membrane processes, electrodialysis(ED) technique plays a more and more significant role in industrial separation. Especially, the separation of monovalent cations and multivalent cations is currently a hot topic, which is not only desirable for many industries but also challenging for academic explorations. The main aim of the present contribution is to view the advances of a wide variety of monovalent cation perm-selective membranes(MCPMs) and their preparation technologies including(1) covalent crosslinking,(2) surface modification,(3) polymer blending,(4) electrospinning,(5) nanofiltration alike membrane,and(6) organic–inorganic hybrid. The relevant advantages and disadvantages with respect to some specific cases have been discussed and compared in detail. Furthermore, we elaborately discuss the opportunities and challenges of MCPMs, the fabricating strategies to take and the future perspectives. | Liang Ge Bin Wu Dongbo Yu Abhishek N.Mondal Linxiao Hou Noor U1 Afsar Qiuhua Li Tingting Xu Jibin Miao Tongwen Xu | 2017 | Chinese Journal of Chemical Engineering2017，25，11： | 8 |
| 3 | Heat Aggregation Mechanisms of Hot Dry Rocks Resources in the Gonghe Basin, Northeastern Tibetan Plateau显示文摘Hot dry rock(HDR) is an important geothermal resource and clean energy source that may play an increasingly important role in future energy management. High-temperature HDR resources were recently detected in deep regions of the Gonghe Basin on the northeastern edge of the Tibetan Plateau, which led to a significant breakthrough in HDR resource exploration in China. This research analyzes the deep temperature distribution, radiogenic heat production, heat flow, and crustal thermal structure in the Qiaboqia Valley, Guide Plain, and Zhacanggou area of the Gonghe Basin based on geothermal exploration borehole logging data, rock thermophysical properties, and regional geophysical exploration data. The results are applied to discuss the heat accumulation mechanism of the HDR resources in the Gonghe Basin. The findings suggest that a low-velocity layer in the thickened crust of the Tibetan Plateau provides the most important source of constant intracrustal heat for the formation of HDR resources in the Gonghe Basin, whereas crustal thickening redistributes the concentrated layer of radioactive elements, which compensates for the relatively low heat production of the basal granite and serves as an important supplement to the heat of the HDR resources. The negative effect is that the downward curvature of the lithospheric upper mantle caused by crustal thickening leads to a small mantle heat flow component. As a result, the heat flows in the Qiaboqia Valley and Guide Plain of the Gonghe Basin are 106.2 and 77.6 m W/m2, respectively, in which the crust-mantle heat flow ratio of the former is 3.12:1, indicating a notably anomalous intracrustal thermal structure. In contrast, the crust-mantle heat flow ratio in the Guide Plain is 1.84:1, which reflects a typical hot crust-cold mantle thermal structure. The Guide Plain and Zhacanggou area show the same increasing temperature trend with depth, which reflects that their geothermal backgrounds and deep high-temperature environments are similar. These results provide important insight on the heat source mechanism of HDR resource formation in the Tibetan Plateau and useful guidance for future HDR resource exploration projects and target sites selection in similar areas. | LIN Wenjing WANG Guiling ZHANG Shengsheng ZHAO Zhen XING Linxiao GAN Haonan TAN Xianfeng | 2021 | Acta Geologica Sinica(English Edition)2021，95，6： | 5 |

| 5 | Performance of BCC-CSM Models with Different Horizontal Resolutions in Simulating Extreme Climate Events in China显示文摘In this study,the performance of the Beijing Climate Center(BCC)Climate System Model version 1.1(BCCCSM1.1)(280-km resolution)and the BCC-CSM1.1 m(110-km resolution)in simulating extreme climate events over China in the last 40 years is compared.Both models capture the main spatial distribution features of heavy precipitation(R95T),the number of consecutive wet days(CWD),the annual count of days with precipitation≥1 mm(R1),the maximum consecutive 5-day precipitation(Rx5),and the numbers of frost days(FD)and summer days(SU).The BCC-CSM1.1 m has a better ability to simulate the detailed distribution of extreme climate events than the BCCCSM1.1,including R95T,CWD,R1,and the simple precipitation intensity index(SDII).However,the BCCCSM 1.1 m does not show an improvement in simulating the number of days with extreme precipitation(R90N),the number of consecutive dry days(CDD),the heat wave duration index(HWDI),the warm day frequency(TX90 P),and cold night frequency(TN10P).This indicates that the simulation of the R95T,CWD,R1,and SDII climate events is more sensitive to the resolution of the model.The improved BCC-CSM1.1 m is used to explore the projection of extreme climate change in China during the 21 st century under the RCP4.5(Representative Concentration Pathways)and RCP8.5 scenarios.The results show that extreme precipitation will increase dramatically over North and Southwest China in the late 21 st century.The CWD index will decrease on the Tibetan Plateau and in northeastern and central China and will increase in other parts of China;R1 will increase in northern China and decrease in southern China;Rx5 will increase dramatically in southern China;FD will decrease and SU will increase over China in the late 21 st century under both emission scenarios,with larger amplitudes in RCP8.5. | Linxiao WEI Xiaoge XIN Chan XIAO Yonghua LI Yao WU Hongyu TANG | 2019 | Journal of Meteorological Research2019，33，4： | 3 |
| 6 | Factors associated with upstaging in patients preoperatively diagnosed with ductal carcinoma in situ by core needle biopsy显示文摘Objective: Patients preoperatively diagnosed with ductal carcinoma in situ(DCIS) by core needle biopsy(CNB) exhibit a significant risk for upstaging on final pathology, which leads to major concerns of whether axillary staging is required at the primary operation. The present study aimed to identify clinicopathological factors associated with upstaging in patients preoperatively diagnosed with DCIS by CNB.Methods: The present study enrolled 604 patients(cN0 M0) with a preoperative diagnosis of pure DCIS by CNB, who underwent axillary staging between August 2006 and December 2015, at Fudan University Shanghai Cancer Center(Shanghai, China).Predictive factors of upstaging were analyzed retrospectively.Results: Of the 604 patients, 20.03%(n = 121) and 31.95%(n = 193) were upstaged to DCIS with microinvasion(DCISM) and invasive breast cancer(IBC) on final pathology, respectively. Larger tumor size on ultrasonography(> 2 cm) was independently associated with upstaging [odds ratio(OR) 1.558, P = 0.014]. Additionally, patients in lower breast imaging reporting and data system(BI-RADS) categories were less likely to be upstaged(4 B vs. 5: OR 0.435, P = 0.002;4 C vs. 5: OR 0.502, P = 0.001). Overall,axillary metastasis occurred in 6.79%(n = 41) of patients. Among patients with axillary metastasis, 1.38%(4/290), 3.31%(4/121)and 17.10%(33/193) were in the DCIS, DCISM, and IBC groups, respectively.Conclusions: For patients initially diagnosed with DCIS by CNB, larger tumor size on ultrasonography(> 2 cm) and higher BIRADS category were independent predictive factors of upstaging on final pathology. Thus, axillary staging in patients with smaller tumor sizes and lower BI-RADS category may be omitted, with little downstream risk for upstaging. | Jing Si Benlong Yang Rong Guo Naisi Huang Chenlian Quan Linxiaoxi Ma Bingqiu Xiu Yun Cao Yue Tang Linxiao Shen Jiajian Chen Jiong Wu | 2019 | Cancer Biology & Medicine2019，16，2： | 3 |
| 7 | Genesis of Geothermal Fluid in Typical Geothermal Fields in Western Sichuan,China显示文摘The hydrogeochemical characteristics of geothermal fluids can reveal the genesis of geothermal systems and act as important references for developing and using geothermal resources.This study presents hydrogeochemical processes and thermal cycle mechanisms of typical geothermal fields in Western Sichuan.Based on the geological conditions in Western Sichuan,29 hot springs in three geothermal fields in the Batang and Litang areas were selected for hydrochemical and isotopic(δD andδ18O)analyses.Furthermore,the temperature of the thermal reservoir was calculated and the upflow cooling process of the hot springs was analyzed.Most of the subterranean hot waters in Batang and Litang are of the HCO3-Na hydrochemical type.The ion variation in Batang is primarily affected by water-rock interactions.There is a strong positive correlation between Na+,B?,and Cl?in Litang,suggesting that they have the same material source.The Na+and metaboric acid content is relatively high,which indicates that the groundwater runoff in both areas is relatively long-lasting,with reduced flow velocity;moreover,the metasilicic acid content is relatively high,which supports this conclusion.Both hydrogen and oxygen isotopes plot near the atmospheric precipitation line,indicating that groundwater recharge is functionally obtained from precipitation.The calculated thermal storage temperatures in Batang and Litang were 88–199℃ and 96–154℃,respectively.The proportion of cold water mixing in Batang was 64%–67%,while that in Litang was 60%–68%.According to the calculated results,the initial thermal cycle depth of the Batang area(4540–4780 m)was greater than that of the Litang area(3150–3960 m).The enthalpy of the deep parental geothermal fluid in Batang was 1550 J/g with a Cl^(-)concentration of 37 mg/L,while that in Litang was 2100 J/g with a Cl^(-)concentration of 48 mg/L. | ZHAO Jiayi WANG Guiling ZHANG Cuiyun XING Linxiao LI Man ZHANG Wei | 2021 | Acta Geologica Sinica(English Edition)2021，95，3： | 2 |
| 8 | Error suppression techniques for energy-efficient high-resolution SAR ADCs显示文摘The successive approximation register(SAR)is one of the most energy-efficient analog-to-digital converter(ADC)architecture for medium-resolution applications.However,its high energy efficiency quickly diminishes when the target resolution increases.This is because a SAR ADC suffers from several major error source,including the sampling kT/C noise,the comparator noise,and the DAC mismatch.These errors are increasing hard to address in high-resolution SAR ADCs.This paper reviews recent advances on error suppression techniques for SAR ADCs,including the sampling kT/C noise reduction,the noise-shaping(NS)SAR,and the mismatch error shaping(MES).These techniques aim to boost the resolution of SAR ADCs while maintaining their superior energy efficiency. | Jiaxin Liu Xiyuan Tang Linxiao Shen Shaolan Li Zhelu Li Wenjuan Guo Nan Sun | 2020 | Journal of Semiconductors2020，41，11： | 2 |
