The inward current in OHCs was totally inhibited after the superfusion of 100μmolIL and 200μmo1/L linopirdine respectively. The outward rectifier K(superscript +) current I(subscript K was the dominant K(superscript +) current in the whole cell currents in Deiters' cells. In the presence of 200μmol/L linopirdine, the current was not significantly affected.

在细胞外液中，加入100μmol/L利诺吡啶后，OHCs中的四乙基二乙胺敏感的钾电流峰电流成分被抑制，稳态电流幅值减小，且电流的失活时间常数明显延长；在细胞外液中加入100μmol/L利诺吡吮后，OHCs的内向性钾电流I被完全抑制；而细胞外液中利诺吡啶终浓度为200μmol/L时，Deiters 细胞的外向整流性钾电流幅值无明显变化。

In this paper, two dimensional shallow flow—pollutants coupled model, which applies uninstructed grid finite volume method and Riemann approximate solver, is used to gain the trend of hydrodynamics and water quality change under the condition of driving force. Mechanism of nitrogen and phosphorous circle of WASP5 is considered in the water quality part of the model according to nutrition actuality of shallow lake in the cities.Xuanwu Lake is object of research in this paper.

Both IS and NA increased heart rate, while propranolol (Pro, 25#mu#g per min) produced a decrease. Phentolamine (Phen, 25#mu#gper min) had no effect. All these effects were similar in vagotomized as well as in unoperated rats. It was shown that the reversal of the effect of sympathetic nervous system on gastric acid secretion is not due to changes in circulation.

IS和NA增加大鼠心率，心得安(25μg/min)显著地减少它，而酚妥拉明(25ug/min)没有明显的作用；IS， NA、心得安或酚妥拉明对迷走神经完整、VT即刻和三月后的大鼠心率的影响均无差异，表明VT后交感神经系统调节胃酸分泌的作用吃变化并非循环改变的结果。

And then the expressing level of AcrAB was detected by Western blotting. The results indicated that the level of resistance to fluoroquinolones of isolates appeared closely correlated with substitution in GyrA and ParC, but expressing level of AcrAB had not significant changes.

序列分析及AcrA的Western blotting检测结果表明，临床分离的鸡大肠杆菌对喹诺酮类药物的耐药水平与GyrA和ParC的突变密切相关，而AcrAB外输泵的表达水平无显著变化。

With determining and comparing the result of the output of chlorine dioxide, the purity of chlorine dioxide, the rate of chlorine dioxide, the capacity of active chlorine and the output of chlorine generated by positive pressure type chlorine dioxide generator under different pressure, this paper draws the conclusion that the effect of pressure to aerogenesis efficiency of chlorine dioxide generator is indistinctive when the pressure is in the range of 0～0.6M Pa.

从化学平衡角度分析，压力增加会抑制正向反应的进行。为了验证实际效果是否如此，本文通过在不同压力下对正压式反应器 ClO2产量、纯度、得率及总有效氯产量等指标进行测定与比较得出，在 0～0.6M Pa的常用压力下，压力的变化对二氧化氯发生器的产气效率无显著影响。

The main results and conclusions are as follows:The trans-1,4 content of polybutadiene increased from 50%to 89%along with the increasing of Al/Li ratio;the trans-1,4 content of polyisoprene increased from 24%to 46%as well as 3,4 content along with the increasing of Al/Li ratio;the microstructure of polystyrene was invariable and atactic.

主要研究结果及结论如下：随着Al/Li的增加，聚丁二烯的反式结构含量从50%增加到89%；聚异戊二烯的反式-1，4-结构含量从24%增加到46%，并且其3，4结构含量也有所增加；聚苯乙烯的微观结构基本没有变化，为无规聚苯乙烯。

Through theoretical modelling and numerical simulation, the dynamic matching relationship is studied on two types of automatic action systems of caseless rifle s.

本文通过对无壳弹枪的两类自动机结构的理论建模和数值仿真，对这两类结构的动力学参数匹配关系进行了深入细致的分析研究，得出三发点射状态下自动机各参数变化对武器性能的影响规律，并对两类自动机进行了分析比

According to the browning phenomenon of Castanea mollissima in plant tissue culture and the activity of the peroxidase and polyphenolic oxidase, the results of my study indicated that the activity of PPO has relativity with the browning of the callus, that is the higher activity of enzyme,the more severity of browning.But POD was not as PPO.

本文对褐变的机理进行初步研究，分别统计和测定培养期间褐变率、PPO活性、POD活性，研究培养过程中酶的活性变化与外植体褐变的关系，结果表明：板栗组织培养过程中，PPO活性与褐变存在显著的相关关系，PPO活性高的处理其褐变率也较高，POD活性与褐变之间无相关性。

There were only 94 vascular plant species, belonging to 50 family and 75 genera. The dominant species in the communities were deciduous broadleaf species Liquidambar formosana, Robinia pseudoacacia, Ailanthus altissima, Acer buergerianum, and Celtis sinensis, evergreen broadleaf species Cinnamomum camphora and Elaeocarpus glabripetalus, and Phyllostachys heterocycla. Robinia pseudoacacia+Cinnamomum camphora community had the highest Shannon-Wiener index (1757) and Phyllostachys heterocycla+Acer buergerianum community had the highest Simpson index (0163), but no consistency was observed between the curves of H and D. For vertical structure, most communities had no significant understory stratification.
