研究了一种高辨率技术，用于对接触带和断层之类地质界线成像，通过追踪由两个水平梯度的ｎ阶垂向导数值的一个垂直梯度组成的增强解析信号极大振幅，可以确定地质界线的轮廓。     

平原水网区产流模式探讨

平原水网区的产流问题，目前尚无较为成熟的方法，一般的降雨径流方法等，因水网地区水量交换复杂，均较难取得理想成果。选择了一个基本闭合的水网区（川沙县张桥乡），采用假设具有稻田和土壤产流结构的产流模式研究了区域内降雨与产流的关系，并取得了较好成果。     

新丰江和枫树坝水库实时洪水预报模型

结合新丰江和枫树坝水库流域的水文气象特征及水库防洪调度的需要，将概念性模型与统计模型相结合，建立了实时洪水预报模型，模型软件与水情自动测报系统于１９９２年先后应用后，由于能准确、及时地提供水、雨情信息，水库在防洪，发电和航运等方面较充分地发挥了综合利用功能，取得了较好的社会和经济效益。     

河道洪水演进有限差分模型糙率系数的率定

以实测水位和计算水位误差绝对值之和最小为目标函数，用修正后的Ｎｅｗｔｏｎ－Ｌａｐｈｓｏｎ迭代法率定河道洪水演进有限差分模型的参数。结果表明，该方法计算了非常有效，且用该方法优化得出的ｎ分布与实际分布相似。     

恐龙蛋化石物质组分研究

研究了ＸＬ０１恐龙蛋化石蛋腔内壁和腔内絮状物质的无机组分。采用常规的双目实体显微镜、偏光显微镜及扫描电子显微镜、电子探针和Ｘ光衍射仪，对蛋腔内主要三种矿物物相的物理性质、化学组成及矿物晶体结构进行了研究。并对腔内的矿物形态、结构特点及有利于有机大分子ＤＮＡ保存的条件做了讨论     

澄江磷矿床风化带划分及矿石工业利用方向

以磷矿石的脉石矿物氧化钙含量（Ｃ＝ＣａＯ－１．３１·Ｐ２Ｏ５）为判别指标，将矿床风化程度划分为强风化、风化、半风化及原生四个带，上三带又分为六个亚带。在总结各带矿石化学组分变化规律的基础上，将矿床划分为五个特征组分含量带，从而提出不同品级、不同风化程度矿石的工业利用方向。     

Geochemistry of Alkaline—Ultrabasic Rocks in the Jijie Complex,Lufeng,Yunnan

is paper is concerned with the geochemical features of major elements,transition metal elements,large ion lithophile elements,rare-earth elements and Sr isotopes in alkaline-ul-trabasic rocks in the Jijie complex of Lufeng,Yunnan Province,which is located in southern Sichuan-Yunnan rift zone,one of Luoci alkaline-ultrabasic complexes in central Ynnnan,Moreover,its origin pertaining primary magma,magma soure region,fractional crystallization,etc.are also discussed in the present paper.     

The Confirmation of a New Type of Chondrites and Their Cosmochemical Significance

The data available show that some Antarctic carbonaceous chondrites are similar to Cl meteorites.Tehy contain a lot of phyllosilicate aggregates and the oxygen isotopic composition of the whole-rock samples is approximate to that of C1 chondrites,so they are named after quasi-C1(Q-C1)chondrites Unlike Cl metcorites,the Q-Cl chondites possess chondrule structrue,and the compositions of hih temperature condensates(chondrule fragments,mineral grains or aggregates)show that the oxygen fugacity varied within a wide range in the surroundings where they were formed,similar to the variation range from E.H.L,LL to C group chondrites.It is inferred that the Q-C1 chondrites could be formed at the edges far from the equator in the whole asteroid region of the solar nebular disk.where the nebula was lower in density and the condensates were lower in accretion velocity,so that the hydration of chon drules and matrix occurred during the late stage of nebular condensation.The discovery of the Q-Cl chondrites and the fact that the earth and other terrestrial planets contain water indicate that at the edges far from the equator in the terrestrial reigion of the solar nebular disk,a large amount of water was incorporated into the lattice of minerals in the condensates as a result of hydration during nebular condensation,and then found its way into the interior parts of the Earth and other terrestrial planets due to accretion.
