冬小麦水分耗散特性与农业节水

本文根据中国科学院禹城综合试验站１９８６年－１９９６年蒸渗仪农田水分模拟试验资料统计；冬小麦全生育期耗水量可达４８２．５ｍｍ，缺水率可达６９．３％；冬小麦全生育不分耗散过程有两个明显的需水峰区和３个关键需水期，为实施节水灌溉提供了实验依据；冬小麦耗水量与环境因子有明显的相关关系，其统计规律可供地下水浅埋区区域灌溉预测参照应用。     

麦田蒸腾需水量的计算模式

本文依据Ｐｅｎｍａｎ－Ｍｏｎｔｅｉｔｈ方法对小麦田田间蒸腾需水量计算方法进行了探讨，得出了一个改进的小麦蒸腾需水量计算模式，对模式中某些参数作了修订；并用中国科学院禹城综合试验站的观测资料对模式进行了计算，结果表明，采用本模式计算充分湿润麦田的蒸腾需水量效果良好     

对煤中锗矿化若干问题的思考——以临沧锗矿为例

本文在综述煤中锗矿化国内外研究现状的基础上，以临沧锗矿为例，深入讨论了在煤系地层中形成超大型独立锗矿床的特殊条件。结果表明，煤是锗成矿极有利的围岩，煤能否富集锗主要取决于有无富锗流体与煤相互作用。     

遥感技术在化工环境保护中的应用

遥感技术获取的可见光、红外及微波信息，可以对化工企业及化学矿山环境污染（水、粉尘、大气、废渣污染等）及环境地质灾害（滑坡、泥石流、地面塌陷等）进行实时动态监测，并可获得较高的社会经济效益，达到地面环保及常规环境地质工作难以达到的效果。特别是对重点大中型化工企业及化学矿山建立环境遥感信息动态监测系统，可以为国家决策部门及时准确地提供环境治理和改造的依据。

乌鲁木齐河源冰川的消融强度函数

通过对天山乌鲁木齐河源１号冰川各物质平衡观测断面近１０年的观测资料和相应的气象资料进行统计分析，得出１号冰川东、西支消融期各月的消融强度函数。统计结果表明，消融强度与气温的关系随着月份的不同而异，同时由于１号冰川东、西两支冰川的朝向差异导致这一关系也有差别     

松辽盆地白垩系的密集段及海水进侵的新证

在总结松辽盆地白恶系层地层特征的基础上，阐述了密集段的地质学和地球物理学标志，经分析，大多数重要反射与密集段相关而并非是层序边界，根据扫描电镜分析结果，在密集段中首次发现了钙质超微化石，为区内白垩纪海水进侵的提供了新的证据，由稳定同位素分析，密集段形成了缺氧，相对可容纳空间最大及水体最深时期。     

A Study on Organic Inclusions in Clastic Reservoir Rocks and Their Application to the Assessment of Oil and Gas Accumulations

Terrigenous clastic reservoir rocks are widespread in China,and nearly all the industrial oil and gas accumulations in eastern China occur in the clastic rocks.The study shows that organic inclusions are mostly distributed in the secondary fissures and pores which were ormed in the process of oil-rock interaction,rather than in the cements or secondary enlargements. The organic inclusions are dominantly organic gas-rich or are composed of pure hydrocarbons.Homogenization temperatures range mainly from 120℃ to 130℃，which shows a relatively high maturity of organic matter.Vertical and horizontal temperature changes provide the grounds for the investigation of basin evolution and thermal fluid-kinetics-model.Fluorescence spectral characteristics o the organic inclusions indicate that oils and gases in the area studied probably have experienced two-stage or two-time migration.Micro-fluorescence rescearch is one of the effective approaches to oil/source correlation and oil migration-stage determination.The abundance and occurrence of organic inclusions is one of the indicators of oil and gas abundance and accumulation in rock layers.With the help of other informatio,organic inclusions can provide the basis for the prospective assessment of oil and gas in clastic reservoir rocks.     

滇西南澜沧群多硅白云母的多型和化学成分特征及其意义

从理论、实验及实际观察的结果都表明，随着压力的增加白云母中绿鳞石的含量显著地增加，可以认为在多期变质作用过程中，尤其是在变质压力不同的多期变质作用下，形成的多硅白云母，其化学成分就会打上不同的烙印。７７个多硅白云母化学成分的统计结果表明，澜沧群低级变质岩中的多硅白云母有两种成因。在Ｎａ－Ｍｇ相关图上，反映了高压和中压变质特征，高压变质的多硅白云母约占７０％。这与用多硅白云母ｂ０值鉴别的高压和中压变质是相吻合的。多硅白云母的多型为３Ｔ和２Ｍ１型，以２Ｍ１型为主     

Radon,Lung Cancer Risk and Environmental Geology in Gejiu Area

The incidence of lung cancer in the Gejiu area of Yunnan Province ranks the first in the world.The radon level(indoor,soil) was measured in the Gejiu area by the SSNTD method from 1990 to 1996,The result indicates an extensive high-level of indoor radon in that area though U and Th are lower in local limestones,The indoor radon level of houses located in the geologic fault zone is 6 times high that 2km far from the fault zone.The reason probably is that the radon level of soil in the fault is 6-8 times high that 1 km far from the faults.our data indicate that a lower range of radon levels,0-100Bq.m^-3,exists in healthy families.However,a higher radon level,over 800 Bq.m^-3,is often found corresponding to that of cancer patients‘ homes(the house-owners are suffering from either lung cancer or leukaemia or liver cancer),Obviously,an increase in lung cancer incidence follows an increase in indoor radon level,The risk of cancer induced by indoor radon is no longer an inference,but a fact.
