第1组为对照组，第2，3，4，5组在日粮中添加不同水平的氟化钠，使日粮中氟含量分别为500，1 000，1 500，2 000 mg/kg，实验期150 d。

After 48 hours of exposure, the point at which organ development is disrupted most profoundly, 57 percent of the tadpoles exposed to 35 mg/L of atrazine had hearts that were smaller than normal, compared with 2% to 3% for the two control groups.

经过48小时的接触，这一点在器官发育的影响最深刻的，百分之五十七的蝌蚪接触到35 mg / L的阿特拉津的心是小於正常，而2 ％至3 ％的两个对照组。

In this research project, we have got a series conclusions:(1) there is no excess argon in the high-pressure white micas being in the orthogneiss;(2) The distribution of excess argon in eclogite is positive correlative with the ratio of Mg/, but negative with the ratio of Na/;(3) The in-situ analyses by using the method of laser probe 39Ar-40Ar show that the age radius from central to margin in a single grain of high-pressure white mica in eclogite;(4) There is no any evidence to prove that the excess argon in eclogite comes from fluid;(5) The excess argon in eclogite inherited from primitive rock during high-ultra high pressure metamorphism;(6) There is no excess argon in the eclogite when its surrounding rock is carbonate.

本项目用综合手段，研究了高压白云母中过剩氩的来源、赋存、分布与岩性、产状、矿物元素和矿物显微结构之间的相关关系，以确定过剩氩在高压白云母中赋存的主要控制因素。初步得出了以下结果：1、高压变质的正片麻岩中的白云母中不含过剩氩；2、高压白云母中过剩氩的赋存和Mg/有着正相关关系，而和Na/呈负相关；3、激光微区氩-氩分析表明，榴辉岩中的单颗粒多硅白云母存在年龄梯度；4、初步否定了高压白云母中过剩氩来自于流体的说法；5、初步认定，榴辉岩中多硅白云母中过剩氩主要是在高压-超高压变质过程中由内部继承的；6、在阿尔金及柴北缘等地围岩为碳酸岩的榴辉岩中的高压白云母不含过剩氩。上述研究结果将推动过剩氩成因研究走向深入。

On the basis of orthogonal experiment, the effect of Mg content and heat treatment on mechanical properties of near eutectic Al Si cast alloys modified with Sr has been investigated.

以正交试验为基础，通过调整Mg含量和热处理工艺，分析它们对Sr变质近共晶Al Si 铸造合金力学性能的影响。

To understand the evolution of the environment of the interior of the Tibetan Plateau during this period, the content Mg/Ca and Sr/Ca of ostracod shells from the Wudaoliang Group has been measured.

为研究高原腹地在此期间环境的演化，对五道梁组中介形虫壳体的Mg/Ca和Sr/Ca的值进行了测试。

The characteristic of Mg/Ca and Sr/Ca of ostracod shell geochemistry and sedimentology of the measured section located in the Tongtianhe basin reflects that during 23.8~21.8 Ma B.P., the evolution of the climate in the area experienced the course from wet and wet to dry, at last to warm and wet.

通天河盆地五道梁组地层中的介形虫壳体的Mg/Ca和Sr/Ca数值的特征，结合剖面岩性特征，反映了23.8~21.8Ma前该湖泊区域气候由湿润－干旱―暖湿的演化趋势。
