Purification and analysis of AT-toxin Firstly, we detected the components of protein and nonprotein, the results showed that AT-toxin is a nonprotein. We have carried out the liquid chromatogram analysis of the toxin. The result indicates that there are many components in this toxin and there are four kinds of components which content is more than others. At last, we have the experiment of separating the cpmpositions with the silica gel and we get four components which are active.

AT-毒素的初步纯化与分析为确定AT-毒素的组分，首先对毒素的蛋白质和非蛋白质组分的毒性进行了测定，结果表明：AT-毒素活性组分为非蛋白质；对毒素进行硅胶G薄层层析，初步分离得到10种组分，其中四种组分具有活性：组分Ⅵ、Ⅶ、Ⅷ、Ⅸ，初步说明了该毒素含有多种组分；进一步对该毒素进行液相色谱分析，也发现该毒素含多种组分，其中四种组分峰高和峰面积较大，含量较高；其致毒活性可能是由这些组分协同作用的结果，它们之间可能存在正协同或负协同作用关系。

Instruments and so on. Being the phenomena of hard to avoid in human observation activity, observation activity, observational error plays an important role in the whole human coqnitive activity when it is bringing about huge negative effect, observational error, with the form of the "lesson by negative example". Stimulates and promotes human epistemic activity to more and more close to truth.

观察错误作为人类观察活动中一种难以避免的现象，在人类的整个认识活动中发挥着重要的作用，它在给人类带来巨大负面作用的同时，以一种"反面教材"的形式刺激并促进着人类的认识活动越来越接近于真理。

By use of the method proposed in last chapter, the design method of system control action optimal distribution and parameters of system control optimum for the control system of multi-structure connection is established according to the two stage design way.

The petrochemistry and geochemistry of Mesozoic volcanic rocks mainly indicate the environmental characteristic of distending structure which bears on orogenic belt. The process of the evolution that earth crust keeps thinning reflects that it is still in the time of extruding orogenesis. Only during the intermittence or relaxation stages of extruding orogenesis, the volcanic eruption of neutral rock and acidic rock were formed in the situation of relative distending structure.

中生代火山岩的岩石化学、地球化学特点，主要显示了与造山带有关的拉张构造环境特征，而地壳由薄变厚的演化过程，则反映了该时期仍以挤压造山作用为主，只是在挤压造山作用的间歇或松驰阶段，相对处于拉张构造环境的情况下，形成了中酸性岩的火山喷发。

And as the Zhuji Dialect sound system may exercise both positive and negative influences on RP pronunciation learning, the writer tries here to focus her study on the latter, that is: 1 articulatory habit; 2 articulatory laziness; 3 parallel transfer.

论文还讨论了诸暨方言音系对英语语音学习所产生的正、负迁移作用，并分析了负迁移作用的成因：1）发音习惯；2）发音惰性；3）平行迁移。本文是在作者掌握了一定的音位学、语音学理论及实践知识的基础上进行构思写作的。

PartⅡ: N-phosphoryl amino acids have many biomimic reactions and the co-participation of the three functional group of phosphoryl, carboxyl and theamino acids side chain are essential for these reactions to occur. To study themechanism and the intrinsic relationship of these three groups will enlight thestudy on the mechanism of enzymatic reaction, the origin of life and otherproblems in the life science.

第二部分：N-磷酰氨基酸的多种仿生化反应是磷酰基、羧基、和侧链基团协同作用的结果，对其反应机理的研究，将对生化反应和生命起源中磷的作用有着重要的意义。

This paper analyses theoretically the take-down function of weight and presser foot, and the cause of the floating up of the fabric edge.

本文从理论上分析了横机上重锤和压脚的牵拉作用和可能产生织物上浮的原因，利用专门设计的压脚装置、口齿-针槽传感器测定了这两种牵位方式的牵拉效果，并分析了实验所得数据和结果，得出了加装压脚装置将有助于牵拉作用的完善的结论。

The trail group which have all regulation elements of SCAP/SREBP pathway can express more fluorscence protein than the control group.［Conclusion］ The experiment provides that the curcumin can upgrade the expression of low density lipoprotein receptor by SCAP/SREBP regulation pathway. The model can be applied for quick screening of the scap ligand drugs and inverstigating the mechanism of the drugs.
