各种大气水汽输送气候计算方法的比较和讨论

比较瞬时法，平均法和逐层平均法３种水汽输送气候计算方案，发现它们的输送方向大致相同，输送量差异显著。瞬时法最准确；逐层平均法次之，但误差的年际波动较大，平均法虽然简单然而误差大。     

莫尔－库仑强度理论的修正

本文对莫尔－库仑（Ｍｏｈｒ－Ｃｏｕｌｏｍｂ）强度理论作了重要修正。指出静水应力不仅对材料固有强度，而且对剪切滑移也有影响，从而得到了一个计及中间主应力影响的剪切强度公式。根据断裂力学的分析，该公式可进一步用于材料的断裂强度的计算。     

BALLOON-BORNE MEASUREMENTS OF AEROSOL VERTICAL DISTRIBUTIONS OVER BEIJING DURING THE SUMMER AND AUTUMN OF 1993

The results of two balloon soundings during the summer and autumn of 1993 from the Xianghe Observation Station are being utilized in a study of the temporal and spatial distribution of the atmospheric aerosols.The balloon,gondola,instrumentation and atmospheric conditions during the observation period are described.The temporal and spatial characteristics of aerosol concentration,size ratio,mixing ratio,and size distribution for both troposphere and strato-sphere are presented and analyzed.

处于高纬向日面的极隙区是太阳风能量、动量和质量可以直接进入地球磁场并到达地球的近地空间的区域。本文简要介绍了极隙区的观测和研究，综述了极隙区的粒子沉降、场向电流、等离子体对流和电离层电流的特征。     

冀北侏罗系上统火山岩中宇宙尘的发现及其地质意义

在冀北丰宁、沽源、赤城一带的上侏罗统火山岩中发现有不同形态的铁质及玻璃质微球粒。经电镜扫描及外貌结构构造的鉴定，显示有熔融、碰撞、逸气、旋纹、冷疑、收缩等特征；经电子探针及Ｘ射线粉晶衍射分析，认为是宇宙尘。对其进行研究不仅有重要的地质意义，而且有找矿意义。

人工合成硅灰石的发光性质与发光机理的初步研究

在２５４ｎｍ紫外光照激发条件下，对人工合成掺入不同激活离子的低温ＴＣ型和高温型假硅灰石的发光性质进行了实验测定，从微观原子能量谱项讨论了在全的硅灰石基质中Ｅｕ＾３＋和Ｇｄ＾３＋的发光机理，分析了Ｂｉ＾３＋对Ｅｕ＾３＋与Ｐｂ＾２＋对Ｍｎ＾２＋的敏化发光条件，初步探讨了掺放Ｅｕ＾３＋的高温型假硅灰石发光强度减弱的原因。     

云南景洪和越南莱州7.0级地震的预报

本文提供了1982年12月、1983年5月在景洪东北先后发生的5.8、5.3、5.7级地震及1983年6月莱州7.0级地震的中期、短期、临震预报的实况和主要依据。中期预报是通过∑E(1/2)释放速率变化出现异常,确定本区处于释放加速段,用最优分割等周期分析法处理得该区活动段将延迟到1983年6月底。利用地震活动位置演变确定活动地点在景洪—江城以南地区。短期预报主要根据孕震过程中依次出现的三个北东向地震条带,b值从1.3下降到0.55,并参考了省内大范围Rn值突变异常,推算出未来主震将大于6.5级。按文献[1]广义调制模式思路,确定震源体处于受调状态,进而外推对莱州7.0级地震作出临震预报。     

Effect of atmospheric overlapping bands and their treatment on the calculation of thermal radiation

The effect of the overlapping band of atmospheric gases and its treatment on the calculation of flux and cooling rate due to the long wave radiation is investigated in detail by a new transmission model for overlapping bands, taking the 15 μm band of CO2 as an example. It is found that the presence of band overlapping has a quite significant influence on radiative fluxes and cooling rates in the upper stratosphere and the troposphere, in particular, at the earth's surface. However, in the middle-lower stratosphere, the overlapping effect appears to be insignificant. It is also shown that the usual wide-band transmission model treating the overlapping effect overestimates the net longwave fluxes in the lower stratosphere and, in particular, in the troposphere including the surface. But, in the middle-upper stratosphere, the contrary is the case.
