Four main radiolysis products of chlorpyrifos and two main radiolysis products of cypermethrin were determined by using gas chromatography tandem mass spectrometry analysis method.

4 kGy剂量辐射，毒死蜱的降解率在98%；12 kGy剂量辐射，氯氰菊酯的降解率在84%；通过GC/Ms分析得出4种毒死蜱主要辐解产物和2种氯氰菊酯主要辐解产物。

A detailed analysis of the experimental results implied that the attractive forces play a main role in the collisional quenching processes of NCO by the quenchers studied in this work, and for some quenchers, the quenching of NCO is probably controlled by the entrance-channel and might be ascribed to the contribution of chemical reactions.

这一加成过程是一个入口势能面属于纯吸引型的无垒过程，故是NCO+O反应的主要通道。二是O原子攻击NCO分子的O原子得到中间物tran-NCOO，再通过C-O键的断裂生成产物CN+OO。该产物通道由于是吸热的，故很难发生。

The N2 pyrolyzed products show better stability than the NH3/N2 pyrolyzed products and have less tendency to crystalline at higher temperature.

N2中热解产物比NH3/N2中热解产物有更好的稳定性，更不易结晶。

The OD of sodium alginate enhanced along with the increasing amounts of added sodium periodates. The molecular weights of sodium alginate were also declined as reaction temperature rising.

结果证实氧化温度上升时，氧化产物的相对分子质量显著降低；增加氧化剂量可获得较高氧化度的氧化海藻酸钠，但同时也降低了氧化产物的相对分子质量。

For the first time,a Raman microscopic investigation of the patinas grown on the beautifully shaped bronzes collected in the Dengzhou Museum ,Penglai City,Shandong Province,was done.

首次运用显微喇曼光谱技术，对山东省蓬莱市登州博物馆馆藏古代青铜器的锈蚀产物进行分析，发现锈蚀产物的成分比较复杂，主要有蓝铜矿、孔雀石、氯铜矿、副氯铜矿、白铅矿、黄铅矾及方解石。

TiO〓/K-M supported Ag/SiO〓 composite ceramic membrane tubes have been prepared and used as a membrane reactor for selective separation of C〓H〓 during the catalytic reaction process of CO〓 partially oxidating C〓H〓. By removing C〓H〓 produced in the catalytic reaction, thermodynamic balance of the reaction is upset and some side reactions from C〓H〓 are avoided, thus the conversion rate of C〓H〓 and the selectivity to C〓H〓 are effectively increased.

本研究设计、制备了硅藻土—莫来石陶瓷管负载的Ag/SiO〓复合膜，并将其应用于二氧化碳部分氧化乙烷催化反应过程中产物乙烯的选择性分离，有效地提高了催化反应的反应物乙烷转化率和产物乙烯选择性。

The article fully introduces the current situation of development and usage of downstream products of DSD Acidg intermediates which are OBA,Direct Dyes,Acid Dyes,and Active Dyes.

DSD酸及合成DSD酸过程中的中间过渡产物NTS酸、DNS酸和DNS酸单还原的产物ANSD酸，这四种化合物统称DSD酸系列中间体，它们是重要的有机化工原料。

As they eat the nitrates, they form nitrites as an intermediate chemical byproduct.

当他们吸收这些硝酸盐的时候，会形成一种可以成为副产物的亚硝酸盐的中间产物。

Second,α,β-unsaturated nitriles were synthesized by three kinds of methods., all the reactions of N-methylhydroxylamine, O-methylhydroxylamine, N-benzylhydroxylamine and O-benzylhydroxylamine withα,β-unsaturated nitriles were carried out, under different temperatures and different solvents. But no desired products were found, though some catalysis were also added.

在不同温度、不同溶剂的条件下，用所合成的α，β-不饱和腈与N-甲基羟胺、N-苄基羟胺、O-甲基羟胺和O-苄基羟胺分别进行反应，没有得到期望的产物，尝试加入了一些催化剂，也没有得到产物。

The lumbar spinal cord in normal rat was immunohistochemically stained with ABC method using HAP1B antibody. Under light microscope, it was observed that HAP1 immunoreactants is mainly distributed in the pericaryon and neuropil in superficial lamella of the gray nucleus with little or no expression in other layers of the spinal horn. The substantia alba show no HAP1B immunoreactants.

对正常大鼠腰段脊髓进行HAP1B的ABC法免疫组织化学染色，光镜下观察显示，HAP1免疫反应产物主要分布在脊髓灰质背角浅层神经元胞体和神经毡内，灰质其他各层无或极少HAP1B表达，白质内未见明显HAP1B免疫反应产物。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
