In general, the phosphoamino acid esters were unable to transfer their phosphoryl group to other hydroxyl nucleophiles even with the presence of imidazole, but the N-phosphoserine and threonine esters were two exceptions.

二、测定了部分磷酰化D—氨基酸的磷酰基转移反应速率常数，并对外消旋化合物的酯交换反应进行了旋光度跟踪，发现磷酰化丝、苏氨酸的对映体有明显的区别。

In cells with active secretion, enzyme reaction product was present in large quantities on the plasma membrane, vacuo le membrane, plasmodesma and in the endoplasmic reticulum, plastid lamellae,and only in small quantities in the mitochondria and small vesicles.

分泌活动旺盛的细胞中，质膜、内质网、质体的内部片层、胞间连丝以及多数大液泡的膜上面都有大量ATP 酶活性反应产物，线粒体和小泡上只有少量酶活性反应产物。

There is also in the skin lesions of psoriasis immune globulin, complement, anti-IsA factor, anti-keratin antibodies and parakeratotic nuclei antibody, etc., these factors result in abnormal T lymphocytes in the immune cycle of separatist injury and the number of T lymphocytes in significantly reduced, such as the Con A stimulus-response is reduced, while phytohemagglutinin and pokeweed mitogen factor is a normal reaction, this phenomenon is to support T-cell subsets flawed.

在牛皮癣的皮损中还有免疫球蛋白、补体、抗IsA因子、抗角蛋白抗体及角化不全细胞核中有抗体等，这些免疫异常因子造成T淋巴细胞的周期分裂性损伤和T淋巴细胞数量明显减少，如对刀豆球蛋白的刺激反应性下降，而对植物血凝素和商陆有丝分裂因子却反应正常，这种现象支持T细胞亚群存在缺陷。

In present work, pyrolysis behavior of several preceramic polymers was studied, and various physical and chemical changes which took place while the preceramic polymer-filler systems were being reaction pyrolyzed were investigated, then phase composition, microstructure and properties of the multiphase ceramics were characterized

本论文在单独研究了几种聚合物先驱体的热解行为的基础上，对多个聚合物先驱体+充填剂体系的反应热解过程中的各种物理、化学变化作了深入探讨，继而研究了由此制备的复相陶瓷的相组成、显微结构和性能的形成和变化规律。

Two T3 He and D3He reactions are chosen for generating the neutrons. The neutron beam is collimated with the multiplex shielding system. The source intensity is monitored by the proportional counter or semiconductor proton recoil telescope. The neutron response curves of ST-401 scintillators with thickness from 0.16mm to 2.00mm are measured versus neutron energy. The uncertainties of experimental results are discussed in detail.
