In the artificial rearing larval honeybee method, 1-day-old larvae were reared in laboratory and 0.1 - 100 ppm pyriproxyfen was added in larval food. A dose respondent effect was found in the larval development of the treated larvae. Results showed that 0.1 ppm pyriproxyfen reduced the eclosion rate of the reared larvae conspicuously, and 1 ppm pyriproxyfen reduced that 84.6% of eclosion honeybee appeared the condition of deformed wings. The 10 ppm pyriproxyfen treatment caused 53.8% melanic death in the pupal stage, and no honeybees succeed in eclosion.

在室内饲养幼虫方面，分别添加0.1-100 ppm百利普芬於幼虫食物中，结果显示0.1 ppm百利普芬即会显著降低饲养幼虫的羽化率，而且添加1 ppm百利普芬会有84.6%羽化蜜蜂出现残翅现象；添加10 ppm百利普芬则会造成53.8%蜜蜂在蛹期黑化而死亡，而且无蜜蜂羽化成功；100 ppm百利普芬则有50%蜜蜂在幼虫期死亡，50%蜜蜂在蛹期死亡，亦无蜜蜂成功羽化。

In addition, our works also indicate that MC-ICPMS technique shows a good potential on Re-Os isotopic measurement. 2. A new method for the determination of low Re-Os abundances and ~(187)Os/~(188)Os in a natural rock sample by MC-ICP-MS has been established in our laboratory. Rock samples were digested in inverse aqua regia in sealed Carius tube for 24 hours at 230°C, then Os was separated from the matrix by CCl_4 solvent extraction, and further purification by microdistillation.

建立了Re-Os同位素样品的化学分离和纯化方法以及MC-ICPMS质谱测定方法：岩石样品的Re和Os化学分离方法是采用Carius管溶样法，结合四氯化碳萃取以及氢溴酸反萃取的方法分离出Os，最后是通过微蒸馏的方法纯化Os；利用阴离子交换树脂的方法分离纯化Re。

Conditions in the laboratory, using traditional microbiological culture method study the different heavy metal concentrations of exogenous Cd2+ for Pistia stratiotes and Myriophyllum spicatum L root-like surface of the impact of micro-organisms .

In this study,under laboratory conditions,using traditional microbiological culture method,select the Pb2+ stress training of Pistia stratiote and Myriophyllum spicatum L. under water culture, through the changs of root- microbial of Pistia stratiote and Myriophyllum spicatum L.,the results show that bacteria,fungi,actinomycetes have different concentrations under Pb2+ stress. It is specificity of ammonification, nitrification,andanti-Nitrosation after Pb2+ stress.

中文摘要：本研究在实验室条件下，用传统的微生物培养法，选择重金属离子Pb2+在水培条件下对大薸和穗状狐尾藻进行胁迫培养，通过测定大薸和穗状狐尾藻根系的微生物区系及与氮循环有关的四种细菌的数量变化发现：细菌、真菌、放线菌对重金属Pb2+的不同浓度的敏感性不同；重金属Pb2+胁迫对氨化、硝化、亚硝化和反硝化四类细菌的影响也表现出各自的特殊性。

The soil and bark samples collected from Yunnan, Hebei and Shanxi provinces of China, and also from Vietnam, were used as the materials in this experiment. And dung pellets of rabbits or goats that had been autoclaved can be used to induce many kinds of fruiting bodies of the Myxobacteria in different colors, sizes, and shapes. We isolated and purified Myxobacteria strains with the improved method which was found by our laboratory.
