In the second experiment, we would like to understand the relationship between sexual performance and sexual motivation. The partner preference test was conducted to measure sexual incentive motivation, and tyrosine hydroxylase immunohistochemistry was used to assay the dopaminergic neuron activity in the medial preoptic area.

在第二部份实验所探讨的是雄鼠的性动机与性表现两者之关系，本实验以EGb 761作为一实验工具，利用伙伴偏好试验测试雄鼠性诱因动机，并利用酪氨酸羟化酶(tyrosine hydroxylase， TH)免疫化学染色方法分析内侧视前区多巴胺神经元的活性。

In addition, the new phosphine-catalyzed cyclization reactions of dimethylacetylenedicarboxylate and methyl propiolate with N-tosylimines are also described.

发展了膦催化下丁炔二酸二甲酯和丙炔酸甲酯与贫电子亚胺的环化反应，这对2-炔酸酯的反应又是一个补充，进一步丰富了膦催化下贫电子炔烃的反应化学。

Injection of 0.06mg had no effect on the puparial color of SEM, and injection of 0.06 to 0.22mg ofβ-alanine gave an intermediate phenotype.

注射试验证明，SEM蛹的黑化可能是由于多巴胺的增多或β-丙氨酸的减少引起的。

ResultsCyromazine had a great toxicity to firs t-instar larvae of housefly with LC 50 value of 43.896 mg/L, and showed less toxic actio n to third-instar larvae and adults of housefly, but reduced the pupate, ecl osion, female oviposition and egg hatch.

结果 灭蝇胺对家蝇 1日龄幼虫的 48h的LC5 0 值为 43 。896mg/L ，对 3日龄幼虫和成蝇的毒杀效果较差，但可引起幼虫化蛹率、羽化率以及雌成蝇产卵量和卵孵化率明显下降；阿维菌素对家蝇 1日龄、3日龄幼虫和成蝇表现出较强的急性毒杀作用，其 48hLC5 0 值分别为 0 。162 1mg/L、1.5546mg/L和 0 。2 10 3mg/L ，而对家蝇生长发育无不良影响。

The compositions by weight percentage of the passivation solution are: 3.12 to 4.74 percent of EDTA, 2.60 to 3.95 percent of hydroxylamine sulfate, 0.52 to 2.37 percent of citric acids, 1.04 to 2.77 percent of sodium pyroborate, the balance being water.

本发明钝化液由重量百分比为：3.12％～4.74％的EDTA、2.60％～3.95％的硫酸羟胺、0.52％～2.37％的柠檬酸、1.04％～2.77％的四硼酸钠和余量的水组成。

the title compound was synthesized and its structure was studied in theory.the schiff base compound was synthesized by condensation of paeonol with furylfurylamine,then it was deoxidized by sodium borohydried.the energies,bound lengths,bound angles,the net charges of main atom and contributive percents of frontier orbital in the title compound have been calculated by software hyperchem 7.0 in half experience method.the yield rate of title compound was 65.6%.the result of calculation showed that the most of the bond lengths and angles in the system were in the the normal range,negative charge mainly concentrate on o1,o2,o3 and n1.the title compound behaves as quadridentate ligand.
