清末川路公司股份制的误区

公司股份制是西制东渐的产物，但在中国近代发生了若干变异。川路公司在股份制运行中，依靠政府行为导致了集股过程中的封建强制性，股东入股缺乏自愿性和营利动机，关心和参与意识淡薄；从实物租向货币资本的转化缺乏市场机制的调节；公司缺乏适当、有效的监控机制。从经理到各级管理人员贪污、挪用股款成风。这是川路公司股份制存在的三大误区，制约了川路公司租股向货币资本的转化和货币资本向生产资本的转化。

Elementary Investigation of Increasing Polarization Performance of Air Electrode for CO2 Transfer

Air electrodes are the key components of Electrochemical carbon dioxide concentrating(EDC) cells. Therefore, the improvement of the polarization performance is beneficial to the increasing of CO2 transfer and cell stability .The preparing process of air electrode is improved by means of the pretreatment of active carbon(AC) and the selection of preparing method of platinum/carbon(Pt/C) powders. Besides, based on the analysis of orthogonal test results, the optimum preparing conditions of Pt/C powders in air electrode are achieved, that is, hydrazine hydrate concentration is 5%～10%, platinum capacity is 8mg/cm2, chloroplatinic acid concentration is 10.0mg/ml and water both temperature is 40℃.     

Electrooxidation of Mn(Ⅱ) on Pb-Sb-As Electrode in Sulfuric Acid

The electrooxidation of Mn(Ⅱ) on Pb-Sb-As alloy electrode in sulfuric acid has been investigated.In order to make the two steps of indirect electrosynthesis of benzaldehyde carried out in the same sulfuric acid concentration and also obtain high current efficiency of Mn(Ⅱ) to Mn(Ⅲ) and high yield of Mn(Ⅲ) oxidizing toluene to benzaldehyde in the mean time,the electrooxidation of Mn(Ⅱ) in 60% H2SO4 has been studied.Experimental results show that high current efficiency of Mn(Ⅲ) (about 75%) is obtained in 60%H2SO4 at 60℃.The reason affecting the current efficiency of Mn(Ⅲ) is discussed,and it is the coordination of sulfuric acid concentration and electrolytic temperature.The law is found that it is suitable for electrolysis at low temperature when sulfuric acid concentration is low and at high temperature when sulfuric acid concentration is high.
