The extremities were titanic, and there was no response to touch stimulations.Our results suggested that Pentobarbital sodium inhibited neuronal firing through GABA_A receptors, therefore the local field potentials and neural firing rates were inhibited; Urethane acted on many kinds of receptors including inhibitory and excitory ones, so the local field potentials did not change significantly; however, because of the multiform receptors on the neurons, the changing of firing rates to different neurons were not the same; Ketamine mainly acted on the NMDA receptors, therefore the local field potentials and neural firing rates were enhanced, and most neural firing rates would be increased.

从这三种麻醉剂的底层作用机制来看，戊巴比妥钠通过作用于GABAA受体对神经细胞发挥抑制性作用，因此表现为场电位和神经元放电的降低；氨基甲酸乙酯同时作用于多种受体通道，既有兴奋性受体，也有抑制性受体，因此，对场电位的影响不大，但对单个神经元来说，每个神经细胞上的受体通道分布差异较大，因此，单个神经元的放电频率变化会有所不同；盐酸氯胺酮主要作用于兴奋性的NMDA受体，故整体场电位活性增加，多数神经元的放电频率也会有所升高。

It also probes into the problems of the tourism development and the geo-environmental traits of the Tibetan-Yi Corridor from a new point of view. Geopolitically, the Tibetan-Yi Corridor acts as a passage and functions as a barrier as well. In the Corridor, the valley from the north to the south of Hengduan Mountains used to be the passage of the ancient migration.

地缘政治学意义的藏彝走廊，既有通道的功能，又具屏障的作用：走廊中横断山脉间南北&纵贯&的河谷就是历史上民族迁徙的通道；而屏障有三：即地貌的屏障、生态的屏障和民族的屏障。

Experiment showed that the separation efficiency in glossily channel for fluorescein sodium was 4.8 x105 per meter, under the electric field 200 V/cm and the separation length 3.5 cm, 17% higher than in rough channel.

用3.5cm分离长度的芯片毛细管电泳分离荧光素钠时，光滑通道的理论板数比粗糙通道提高17%，达到48万/米的理论板数。

ASIC2b subunits do not form functional homomeric channels,but they may associate with other subunits to form heteromeric ASICs with distinct properties.

ASIC2b不能形成功能性同聚体通道，但是可以和其它亚单位装配在一起，形成具有不同性质的异聚体通道。

According to the productions which had been explored in the experiment and the Chemical process for silicon epitaxial growth in a SiHCl3i/H2 system Hitoshi Habuka etc.

根据实验检测到的产物以及由Hitoshi Habuka等人所提出的SiHCl_3／H_2反应体系的外延生长过程，首先设计了该反应体系在气相中的可能反应通道和在Si衬底表面上的可能反应通道。

In gas phase, there are two reaction paths, the concerted and stepwise mechanisms, both of which produce the experimental product, hydroxamic acid; the stepwise mechanism is predominant.

在气相中均找到两条反应通道，即协同机理和分步机理，均生成实验产物氧肟酸，而且分步机理均为优势通道；除2-甲基-2-亚硝基丙烷的反应没有协同途径外，在溶剂中反应机理与气相中的类似。

As protein substances embed or impenetrate in membranes, a hydrophilic passage is formed in the three dimensional structure of protein, called ion-channel.

细胞膜上有蛋白质性质的物质嵌在膜上，或者贯穿细胞膜，从而在蛋白质三维结构内部形成一个亲水性通道，称作离子通道。

However, the result is spatially discrete and temporally incontinuous when we calculate the energy of the solar radiation on the Earths surface using general meteorologic parameter.

本文在对极轨气象卫星第一、二通道反照率观测值与地表总辐射关系的物理基础进行分析后，运用回归分析的方法，建立了利用第一、二通道反照率观测值反演计算地表太阳总辐射的回归模型。

A port is a communication channel, also is invadable channel.

一个端口就是一个潜在的通信通道，也就是一个入侵通道。

The air is then drawn into channel 30, flows past the basket-like fan 28, into the outlet channel 30a and out of the louvered vent 16a.

此后，空气被吸入通道30，流经篮式风扇28而进入出口通道30a，并从百叶式通风口16a流出。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
