Immune POF model elicited by immunization in subcutaneous with antigen sourced isotype animal ovaries can cause growing follicles and mature follicles decrease obviously, the morphology of oocytes and zona pellucida abnormal, the adjacent granular cells disorder and atresic follicle increase.

以同种动物卵巢为抗原主动免疫建立的免疫性POF模型可致生长卵泡和成熟卵泡数明显减少，卵母细胞及透明带形态异常，周边颗粒细胞排列紊乱，闭锁卵泡增多，病理损伤随免疫时间延长而加重。

The result indicates that Bassia rapa L. 65%, 95% alcohol extract and water extract can prolong the survival time of mice in hypoxia under ordinary pressures significantly. It can also prolong the survival time of mice with acute cerebral ischemia and sodium nitrite significantly, and increase the number of erythrocytes and the content of hemoglobin. It demonstrates that Bassia rapa L. extract has anti-hypoxia activity.

结果表明，芫根水提取物、65%乙醇提取物及95%乙醇提取物均能明显延长模型小鼠在常压缺氧、急性脑缺血性缺氧及亚硝酸钠中毒时的存活时间，并可增加外周血象中红细胞数与血红蛋白含量，显示芫根提取物具有抗缺氧活性。

The conidia formation was inhibited on the PDA agar plate with the culture filtrates though the spores germinated and formed their hypha in certain degree. Growth suppression, increasing branches of their offset and swelling in the middle and/or the top of the hyphae were observed with microscope and scanning election microscope. The longer time the treatment, the more severe the hyphae aberration was, some of them were altered as beadlike, some offsets formed cluster-like structure.

在普通光学显微镜和扫描电子显微镜观察显示，两菌株均可抑制香蕉炭疽病菌菌丝生长，造成菌丝分支增多，顶端和中央膨大，随着时间的延长畸变结构增加，菌丝呈念珠状或菌丝分支显著增多，且顶端细胞变形膨大聚集成簇，菌丝壁穿洞，内含物质泄漏，终使细胞崩解和消融，变成球状的空泡。

To evaluate the toxicity of the sludge, dredged from Victoria Port of Hong Kong , to marine benthonic animals lived in its pouring region, the toxicity test of the sludge to marine benthonic animals, including benthonic shellfish and crustacean, has been conducted.

为了评价香港维多利亚港疏浚淤泥对倾倒海区海洋底栖动物的影响，进行了两种底栖贝类和一种底栖甲壳类的生物毒性累积试验。结果表明，试验底栖贝类结蚶和缢蛏暴露在试验淤泥中240h和480h后，随暴露时间的延长，累积率增大。

In the three systems, system realizes the crosslinking of PVC bases on the peroxide crosslinking mechanism, the tensile strength of crosslinked PVC has been improved somewhat, the IR spectrum of gel demonstrates that there are characteristic absorption peaks of n-alcohol that belongs to ethanol amine and benzenoid group. From the analysis of gel structure , deduces that the mechanism of crosslinking reaction: under the initiations of peroxide and high temperature, PVC yields macromolecules free radicals, at the same time , styrene"s polymerization and grafting onto PVC takes place, at last the system forms crosslinking structure through coupling between radicals; confirms that triethanol amine can absorb HC1 produced by degradation of PVC, so improves the crosslinking efficiency of peroxide, decreases the HCl"s promotion for PVC"s degradation; deduces that triethanol amine can activate the PVC macromolecules and prolong the free radicals" life-time of PVC macromolecules; the effect to the PVC macromolecule makes styrenes graft reaction easy, and thus improves the crosslinking efficiency.

三种体系中三乙醇胺/过氧化二异丙苯/苯乙烯体系基于过氧化物交联机理实现了聚氯乙烯的交联，聚氯乙烯交联后拉伸强度有一定提高，凝胶红外光谱分析证实了凝胶结构中含有乙醇胺的伯醇基团特征吸收和苯环的特征吸收，由凝胶结构分析，推断出交联反应的机理：聚氯乙烯在过氧化物和热作用下产生大分子自由基，苯乙烯在过氧化物和大分子自由基的作用下发生聚合和接枝反应，最终通过自由基之间的偶合产生交联；证实三乙醇胺可以吸收聚氯乙烯分解产生的HCl，提高了过氧化物的交联效率，消弱了HCl对聚氯乙烯降解的促进作用；推断三乙醇胺可以活化聚氯乙烯大分子并有可能使聚氯乙烯大分子自由基存在的时间得以延长，对聚氯乙烯大分子的作用使苯乙烯的接枝反应易于发生，从而提高了交联效率。
