Thermodynamic analysis shows that electrochemical reduction of HSO-3 into dithionite is controlled dynamically, not thermodynamically, and that concentration decrease of the sulfur-compounds will be helpful to increase thermodynamic stability of dithionite produced by electrochemical reduction of HSO-3.3figs.,2tabs.,9refs.

热力学与文献研究结果表明，HSO-3电化学还原为S2O2-4的过程为动力学控制，当溶液中含硫物质的浓度均为0.001mol*dm-3时，HSO-3电解还原为S2O2-4的热力学稳定性提高。图3，表2，参9。

Specifically, transcendental reduction is necessitated by the relationship between phenomenology and anthropology. Eidetic reduction, intuition of essence and ideation, is necessitated by the relationship between phenomenology and psychology.

具体地说，从现象学与人类学的关系来说明现象学的先验还原方法及其必要性；从现象学与心理学的关系来说明本质还原方法及其必要性。

So the eidetic reduction is not a simplification or concentration into concepts, but rather the opposite:"it makes the world appear as it precedes every cognitive construction, in its full ambiguity, irreducibility, contingency, mystery and ultimate indeterminacy"(van Manen 2002d).

因此，本质的还原，是不是一个概念，简化或到集中，而是恰恰相反："它使世界上出现，因为它前面每一个认知的建设，在充分含糊，不可还原性，应急，神秘和最终的不确定性"（范梅南2002d）。

The optimal environmental conditions in batch culture for PCP dechlorination were: pH 7, temperature 38℃ and redox potential E(subscript h 200 mV.

PCP最佳还原脱氯温度为38℃，最佳pH为7，低的氧化还原电位(200mV)有利于脱氯的进行。
