另外，本实验探索出一种可行的回收氰化物新工艺，在硫酸解吸过程中，研究了硫酸解吸的时间、浓度和温度因素对氰和锌的解吸率的影响；在氨水解吸实验中探讨了时间、温度、浓度、超声波等因素对铜解吸率的影响。

Directly plating process without cyanide copper.

替代传统的锌合金氰化镀铜打底，无毒，工艺简单。

A series of copper salts were prepared and studied in the selecitive oxidation of cyclohexane.

只要找到了适当的反应物，在合适的温度下，聚苯胺有可能是非常理想的加氢、脱氢催化剂。

The influence of reaction time,dosage of catalyst and molar ratio of cyclohexanol/acid were investigated in the presence of copper sulfate used as catalyst.

在较优催化剂CuSO4.5H2O催化下，考察了反应时间、催化剂用量、醇酸比等因素对酯化率的影响。

This paper has described several influential factors concered with determination of work capacity of screw friction press with copper cylinder adopted as specimen, and analysed the variation law of effects of several factors on tho result of calculation.

全—一A： 2(1)由于滑块的速度和飞轮转动的角速度之间有确定的关系，所以一般测量滑块的移动速度从而确定压力机的做功能力(滑块与螺杆的动能在这里略而不计)。

PSE7 and SOJB had the similar binding proteins in tobacco, suggesting that they may share some similar biological functions. The ubiquitin-conjugating protein and peptidase involved in protein degradation were found binding with SOJB but not PSE7. Both SOJB and PSE7 could bind with transmembrane transport protein, SOJB bound with copper transporter protein, and PSE7 bound with water channel protein. The results suggested that the target of SOJB and PSE7 may be located in cytoplast.

PSE7和SOJB在烟草中存在几个相似的结合蛋白，表明二者具有共享的生物学功能；SOJB能与肽酶和泛素结合蛋白（与蛋白质降解有密切关系）互作，而PSE7没有筛选到类似蛋白；SOJB和PSE7均能与跨膜运输蛋白结合，PSE7与水通道蛋白结合，SOJB与铜离子转运蛋白结合，表明二者在胞质内均存在作用靶标。

While copper is essential, it is also a potent cytotoxin when allowed to accumulate in excess of cellular needs.

铜离子参与的反应也产生高活性氧包括羟基游离基。
