Our result showed the expressed HμOR desensitization could be induced by acute stimulation of μ-selective agonists DAGO and Ohm in a dose-dependent manner in G protein level.

在昆虫细胞表达的HμOR，用μ选择性激动剂DAGO和Ohm急性预处理，也同样导致HμOR的脱敏，并且随着预处理激动剂浓度增加，脱敏现象愈明显。

And this strain degraded H〓S without lag time. The heterotrophic bacteria's generation period was short and its growth was rapid. The result of experiment indicated when the strain Hm-6 was applying to the packed tower, the startup was more quickly and the control was more convenient than the autotrophic bacterium. Applying to deodorize the H〓S, the better removalability could be got. At the same time, comparing with the system used at home of which the biofilm directly formed with activated sludge, it runs in the neutral condition, has lower corrusivity to the equipment and was liable to handle. And this system didn't need the acclimation to become biofilm, so it can save a rather long acclimation time.

异养菌虽然不以硫化物作为能源物质，但其世代周期短、生长迅速，运行管理比自养菌更为方便，具有周期短，启动迅速等优点，接种了菌株Hm-6泥炭生物填料塔，对低浓度H〓S有较高的去除效果，且没有延迟期，与国内通常采用的直接以活性污泥挂膜的方式相比，应用该菌的脱臭系统在中性条件下运行，对设备的腐蚀性较低、运行过程较易控制，具有很好的应用前景。

To further explore the origin of the blue shift for C-H bond not directly participating in H-bond formation, we present a theoretical investigation on the complexes formed by formamide and small molecules such as HF et al.

为了进一步研究不直接参与氢键形成的C-H键蓝移的起因，我们对甲酰胺和HF等小分子形成的氢键复合物进行了理论计算研究。

From the fact that the hydrogens of microbial methane originate in water, it may be deduced that with the reduction of HCO(superscript – subscript 3) a transfer of H atom occurs from the O atom to the C atom within HCO3 anions formed by the disassociation of dissolved CO2 in water, and furthermore, the formyl group forms.

由前人研究结果推断HCO(上标–下标 3)在脱去两个O原子的同时，可能发生了亲核重排，羟基H原子迁移到C原子上，形成了甲酰基HCO(上标-，使甲烷的第一个H原子来源于水。

A new universal hybrid topology is brought forward. Two types multilevel inverter: equal DC voltage and DC voltage in geometric proportion is studied, besides this, simulation and experiments on SVPWM applied on cascaded H-bridge inverter is also studied.

提出了多电平逆变器的一种通用组合拓扑结构，针对这种拓扑结构重点，研究了直流侧电压相同及等比变化的两类级联拓扑以及级联H桥逆变器的矢量控制方法；并对级联H桥逆变器的矢量控制方法做了实验研究。

The properties of most acids, especially in water solutions, arise from the hydrogen ion (H+, also referred to as the hydronium ion, H3O+, the form in which H+ is found in a water environment).

大多数酸尤其是在水溶液中的酸，其各种性质都是因存在氢离子(H+，亦可产生水合氢离子H3O+，因此任何水的环境都可发现氢离子)而产生的。
