本文介绍了定位格架夹持力辐照松弛研究中几种适用的测量方法及其特点，如在实验室研究中测定位格架弹簧力的松弛，在辐照后的17×17验证组件中测燃料棒在栅元中的移动力和滑动力、在抽出燃料棒的空栅元中测栅元摩擦力及栅元尺寸等方法。

Four kinds of hapten with the similar structure of parathion-methyl were designed and synthesized. These four haptens were coupled with different length and structural spacer arms through nitro-group or methoxyphosphate group of parathion-methyl. Then six kinds of hapten-protein conjugates were synthesized by different methods.

根据甲基对硫磷的结构特征，分别从甲基对硫磷的硝基一端或磷酸酯基甲氧基一端引入一定长度的间隔臂和活性基团，设计并合成了 4种结构的半抗原；针对各种半抗原所带活性基团的性质，通过多种方法制备了与不同的载体蛋白偶联的人工抗原。

The effects of hapten structure on antibodies properties and hapten heterology on ELISA sensitivity were also investigated. The results show that haptens with simple spacer-arm can generate antibodies with desired properties, and hapten heterology can improve ELISA sensitivity significantly.

建立检测硫代磷酸二乙酯类农药的间接竞争酶联免疫分析方法，分析探讨了免疫半抗原结构对抗体特性的影响，并阐述了包被半抗原结构对ELISA灵敏度的影响规律。
