| 2 | 赤峰药王庙、夏家店遗址试掘报告显示文摘1959年,我们在辽宁省昭乌达盟(原属内蒙古自治区)境内做过短期的调查,发现过去称为'赤峰第二期文化'的遗物,可能是内涵不同的两种文化遗存,不仅器物上有明显的区别,在分布地域上也有所不同。为了作进一步的考察,1960年春,我们选定在赤峰近郊药王庙和夏家店两地做了试掘。试掘简报发表于《考古》1961年第2期。简报提出了两种文化的看法。随后,我们和一些兄弟单位又在昭盟和邻近地区做了一些调查发掘。 | The Inner Mongolia Archaelogical Team,Institute of Archaeology,Academia Sinica | 1974 | 考古学报1974，，1： | 68 |

| 5 | Efficient Management of Nitrogen Fertilizers for Flooded Rice in Relation to Nitrogen Transformations in Flooded Soils显示文摘Recent progresses in efficient management of nitrogen fertilizers for flooded rice in relation to nitrogen transformations in flooded soil were reviewed.Considerable progress has been achieved in the investigation on the mechanism of ammonia loss and the factors affecting it .However,little progress has been obtained in the investigations on nitrification-denitrification loss owing to the lack of method for estimating the fluxes of gaseous N products.Thus,so far the management practices developed or under investigation primarily for reducing ammonia loss are feasible or promising,while those for reducing nitrification-denitrification loss seem obscure,except the point deep placement. In addition,it was emphasized that the prediction of soil N supply and the recommendation of the optimal rate of N application based on it are only semi-quantitative.The priorities in research for improving the prediction are indicated. | ZHU ZHAO-LIANGLMCP, Institute of Soil Science, Academia Sinica, P.O.Box 821, Nanjing 210008 (China) | 1992 | Pedosphere1992，2，2： | 28 |

| 7 | OBSERVATION AND MODEL ANALYSES OF POSITIVE CLOUD-TO-GROUND LIGHTNING IN MESOSCALE CONVECTIVE SYSTEMS显示文摘The analyses of spatial and temporal characteristics of positive cloud-to-ground(CG)lightning for four mesoscaleconvective systems and two severe local convective systems in 1989 and 1990 show that positive CG flash rate usuallyhas two peak values.The major peak occurs during the developing stage of the storm and most of the positive CGflashes originate at the lower part of the storm.The minor occurs during the dissipative stage of the storm and most ofthe positive CG flashes originate at the upper part of the storm,especially in the region of the wind divergence in thestorm anvil.The positive CG flash rate is almost an order of magnitude larger in the developing stage than in thedissipative stage.The appearing time of the peak of negative CG flash rate is in accordance with that of the valley of pos-itive CG flash rate.The higher the intensity of the radar echo,the higher the positive CG flash rate.Most of the positive CG flashes oc-cur when the weak echo area is larger,and mostly originate in the region where the radar echo intensity is about 10dBzand in the back region of the moving storms.The spatial distribution of the positive CG flashes is much more dispersivethan that of the negative.The mesoscale analysis reveals a bipolar lightning pattern.The mean bipole--length reaches itsminimum during the mature stage of the storm and reaches the maximum during the developing stage of the storm.The vertical distribution of the charge density is calculated by a one-dimensional charging model.Then,we discussthe producing condition of the positive CG lightning and forming cause of charge structure mentioned above. | Yan Muhong Guo Changming Qie Xiushu Ge Zhengmo Zhang Guangshu Lanzhou Institute of Plateau Atmospheric Physics,Academia Sinica,Lanzhou 730000 | 1992 | Acta meteorologica Sinica1992，6，4： | 16 |

| 13 | Formation and Evolution of Vertisols in Huaibei Plain显示文摘The objectives of the present paper are to restore soil-forming environment of the Vertisols,to reveal their regularities of formation and evolution and to found soil chronology.In regard to formation and evolution of the Vertisols in the Huaibei Plain,they have undergone 3 cycles of deposition-formation during different geologic time (Q3^3;Q4^2 and Q4^3).Therefore,they are considered as the soils developed on heterogeneous parent material.The Vertisols as a paleosol can be divided into relict Vertisols and buried Vertisols.The former is shajiang black soils called by local people,the latter is shajiang black soils underlying Warp soil or warp soil horizon. | LIU LIANG-WUInstitute of Soil Science, Academia Sinica, P.O.

| 14 | MODELLING AND STABILITY ANALYSIS OF POPULATION GROWTH WITH SPATIAL DIFFUSION显示文摘In recent years, population growth models with spatial diffusion have beenextensively studied by many authors (for example, see [1-5]). In this paper, a populationgrowth model is considered with a discrete age-dependence and spatial diffusion, and isinvestigated in a semigroup framework. The spectral properties of the population oper-ator are given. On the basis of such spectral consideration, the asymptotic behaviourof the semigroup generated by the population operator is obtained. Finally, a nonlinearpopulation growth model is considered and its stability is analyzed. | W.L.CHAN FENG Dexing Department of Mathematice,the Chinese University of Hong Kong,Shatin,N.T,Hong Kong Institute oj Systems Science, Academia Sinica, Beijing 100080, China | 1993 | Systems Science and Mathematical Sciences1993，6，4： | 10 |
| 15 | General theory and design of microperforated-panel absorbers显示文摘A general theory of microperforated-panel absorbers is proposed on the basis of equhaleot circuits. The characterizing parameters of the absorber are its relative acoustic resistance γ, the diameter d of the perforations and the resonance frequency fo. The later two form the perforate constaot k = , which, together with γ, decides the structure and characteristics of the microperforated-panel absorber. The maximum value of the absorption band width △f/f0 is (4/π)tan-1(1+γ), as k approaches zero, and it does not change much as far as k is less than 1, the cavity depth is nearly a quarter wavelength of the resonance frequency For large values of k, the absorption band narrows down significalltly and the cavity depth required becomes a small fraction of the wavelength. The general properties of the microperforated absorber are discussed. | MAA Dah-You(Institute of Acoustics, Academia Sinica Beijing 100080) | 1997 | Chinese Journal of Acoustics1997，16，3： | 9 |
