Using mordern physical chemistry techniques (such as XRD、 TG-DTA、 IR、 XPS and 〓Xe-NMR)、 chemical adsorption techniques (NH〓-TPD、 H〓-TPD、 TPO、 TPR etc.) and pulse flow microreaction of n-hexane、 methylcyclopentene and n-hexane containing 0.2ppm thiophene, we studied mainly the following three points:(1). the changes occured during the calcination pretreatment of Pt ammine complex supported on β and L zeolites;(2). the effect of structure and acidity-basicity of zeolite on the dispersion and electron state of Pt particles; and (3). the influence of second metal component on the reactivity of nhexane aromatization and sulphur-resistance of Pt/L zeolite catalyst. Several interesting and valuable results are obtained and summerized as follows

Using the proposed identification and control strategy, the identification results of two kinds of systems and the simulation of a bilinear process control system are presented. The generality of the model and the simplification of identification and control method together with the simulation results show that the above strategy has strong possibility to nonlinear system and high order system identification for process industries and the excellent control performances superior to a standard PID controller for the same process.

To investigate whether the expression of cdc2 and cyclin B1 in spermatogenic cells during spermatogenesis is actually a temperature dependent event, in situ hybridization, Western blotting and immunohistochemistry analysis were used to study the expression of cdc2 and cyclin B1 in normal and cryptorchid testis. Results showed that heat would differentially hurt male germ cells in different developmental stages during spermatogenesis, especially the pachytene primary spermatocytes. Most of spermatogonia in contralateral cryptorchid testis were not harmed fatally by heat as yet, indicating that spermatogonia could resist to beat to a certain extent. In this case spermatogonia could develop to pachytene/diplotene primary spermatocytes, but they could not acquire the ability to complete the transition from mitosis to meiosis, and then appeared to go through apoptosis. Therefore, we could not find the descendants of meiosis: secondary spermatocytes and round spermatids, elongated spermatids and spermatozoon. The abdominal temperature had no significant influence on the transcription of cdc2 and cyclin B1 in the spermatogonia and pachytene/diplotene primary spermatocytes. In normal rabbit testis, cyclin B1 increased in the pachytene/diplotene primary spermatocytes before meiosis and reached its peak in the spermatids.

为了解精子正常发生过程中cdc2和cyclin B1表达的低温依赖性，我们利用原位杂交和免疫组化等方法，研究了正常和隐睾精子发生过程中cdc2和cyclin B1的转录和翻译调控活动，结果表明：（1）热对各阶段的雄性生殖细胞都有损害，粗线期的初级精母细胞尤为敏感，实验性隐睾内的精原细胞尚未完全受到"致命"影响，说明精原细胞对热有一定的耐受性，但即使成为粗线期／双线期初级精母细胞，却未能获得由有丝分裂过渡到减数分裂的能力，呈现不同程度的凋亡，所以在整个切片中找不到源自减数分裂的产物----次级精母细胞、圆形精子细胞，更谈不上长形精子细胞和精子的形成；（2）腹腔高温未明显地影响隐睾精原细胞和粗线期/双线期初级精母细胞中cyclinB1和cdc2的转录，说明高温并不是通过影响cyclin B1和cdc2的转录活动而导致生精过程阻断的；（3）正常兔睾丸组织中，〓在精原细胞和粗线期／双线期精母细胞中均有表达：cyclin B1蛋白在减数分裂前期的粗线期／双线期初级精母细胞中的表达量增加，于变态末期的精子细胞中达高峰。
