对于分散良好的铂，表面上的全部粒子在表面上基本上都能被相同数量的氧原子或氢原子进行化学吸附。

We want to interpret the sensing mechanism of copper oxide by the point of view of catalytic chemisorption theory; the cause of sensitivity of copper oxide was the CO chemisorption on the oxygen active regions.

并从催化理论上对氧化铜的气敏机理进行解释，认为CO在氧化铜表面的化学吸附是氧化铜气敏材料的气敏性质产生的原因。

Carotid body:a chemoreceptor located near the bifurcations of the carotid arteries that monitors changes in the oxygen content of the blood and helps control respiratory activity.

颈动脉体：位于颈动脉的分支点附近的化学感受器，监测血液中氧含量的变化并协助调控呼吸活动。

This review and our recent studies suggest that:(1) baroreceptor reflex is blunted in heart failure;(2) central angiotensin Ⅱ and reactive oxygen species play an important role in blunted baroreceptor reflex;(3) cardiac sympathetic afferent stimulation and chemoreceptor reflex inhibit baroreceptor reflex; and (4) exercise training normalizes abnormal reflexes in the heart failure state.

本综述及我们近年的研究表明：(1)在心力衰竭状态下压力感受性反射功能明显减弱；(2)中枢血管紧张素Ⅱ和活性氧在压力感受性反射功能失调中发挥关键作用；(3)心交感传入刺激和化学感受性反射能抑制压力感受性反射；(4)适当的运动可以部分纠正异常的心血管反射活动。

Potassium Chlorate is a compound containing potassium, chlorine and oxygen. It is often used as a disinfectant and in fireworks and explosives.

氯酸钾是一种含有钾、氯和氧的化合物，经常用在消毒剂、烟火和炸药中。

The gas coming off the potassium chlorate is oxygen.

从氯化钾中释放出的气体就是氧气。

A new chlorate cell system with a DSA anode and an oxygen cathode was set up.

利用氧阴极与DSA阳极组装成一种新型氯酸盐电解槽。

In my opinion, Cu complexes with unsaturated alcohol to form a complex compound; the nitrogenous compound introduced serves as the complex compound's stabilizing agent and reduces activation energy of reaction; TMPO serves as oxygen carrier and displays it's selective oxidation function. This new method and mechanism also demonstrates significance to other similar organic reactions.3 In the chlorohydrin reaction, NaCIO is replaced by Ca2see Chapter4.4.3.4(2 .A, this method hasn't been reported in previous literature,which exerts more buffer action to the react system, the yield increased from 52% to 88.6%; at the same time it solve the problem of poor stability and low percentage composition of NaCIO.

认为：CuD与烯醇形成络合物：含氮有机物的引入起到稳定络合物，降低活化能的作用：而TMPO则充当携氧子起传递氧的作用，并具有选择氧化功能：这种新的方法和理论对类似的反应(不饱和醇类在络合体系下选择性催化氧化为对应的醛也具有重要的指导作用。3在异戊二烯的氯醇化反应中，用次氯酸钙代替次氯酸钠见第4章4.3.4(2.A，本方法未见文献报道，使反应系统更加温和，收率由52%提高到88.6%：并解决了次氯酸钠稳定性差、有效氯含量低的实际问题，具有重要的实用意义。

We selected copper chlorophyll and copper sodium chlorophyllin to have experiments of culturing microalga, under the same of illumination and the concentration of nutrition, comparing with copper ion. The results show that under the condition of illumination, a certain quantity of photosensitizer can produce a great quantity of active oxygen, which has strong effect of death; Copper chlorophyll and copper sodium chlorophyllin have very strong influence to growth of microalga.

由于叶绿素铜钠是水溶的，而叶绿素铜是油溶的，导致微藻对它们吸附性质的不同，微藻吸附的少量叶绿素铜钠促进了微藻的生长，而叶绿素铜在低浓度时对微藻的生长具有促进作用，在高浓度时可以抑制微藻生长、甚至杀灭微藻。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
