The results suggest that veratridine and aconitine induce different firing patterns in injured DRG neurons, which may relate to their inhibitory effects on different binding sites of the sodium channel.

实验结果表明，藜芦碱和乌头碱在受损的背根节神经元可以引发不同的放电模式，这可能与它们结合于钠通道上不同位点的抑制作用有关。

The firing patterns induced by veratridine and aconitine, inhibitors of inactivation gate of sodium channel operating on different binding sites, were compared.

藜芦碱和乌头碱是钠通道失活门的抑制剂，但二者作用于不同的位点，前者结合于D2-S6，后者结合于D3-S6。我们比较了这两种试剂引发的放电模式。

In the same neuron, veratridine (1.5～5.0 μmol/L) caused slow wave oscillations of interspike intervals, while aconitine (10～200 μmol/L) caused tonic firing.

结果发现，在同一神经元，藜芦碱(1.5～5.0 μmol/L)可以引起放电峰峰间期的慢波振荡，即峰峰间期由大逐渐减小，然后又逐渐增大，形成重复的振荡波形，每个振荡持续约数十秒至数分钟；而乌头碱(10～200 μmol/L)则引起强直性放电，即峰峰间期逐渐减小，然后维持在一个稳定的水平。

This paper analyzes the components of washing bottle machine with pairs of end pass in and out and the technological process of washing bottle,expounds the synchronous operation principle of the transmission system of the washing bottle machine.

叙述了双端式进出瓶洗瓶机的组成和洗瓶工艺过程，论述了洗瓶机传动系统的同步运行，利用电导率检测碱液浓度的控制及碱液温度控制原理。

Nitrate serves as a terminal election acceptor in Alcaligenes faecalis,when it grows anaerobically with lactate and ammonia as the carbon and nitrogen sources,respectively.

粪产碱菌生长在NH_4~+和NO_3~-两种氮源的介质中时，优先利用NH_4~+，在好气条件下，NH_4~+的存在抑制了粪产碱菌对NO_3~-的同化作用。

The aim of this research was based on enhancing the anaerobic digestion efficiency of straw by thermo-alkaline pretreatment in which mainly studied the effect of thermo-alkaline pretreatment on solubility of straw. And then the straw after pretreatment was anaerobically digested to verify effects of pretreatment on anaerobic digestion of straw.

本研究以提高秸秆厌氧发酵效率为目的，采用热碱预处理方法对秸秆进行预处理，研究预处理温度、碱用量对秸秆可溶性的影响，将预处理后的秸秆用于厌氧发酵，检测其对厌氧发酵结果的影响。

The brown seeds percentage did not have significant differences in bagged and controlled. S. salsa is probably an autogamous plant.

对套袋和不套袋的盐地碱蓬比较发现，它们的结实差异不显著，所以盐地碱蓬很可能是自花授粉的植物。

Schiff base is the Types of organic compounds which contain C-N double bond of the imine or azomethine group characteristics.the early research focus on Amine Schiff base reduction.

席夫碱主要是指含有碳氮双键的亚胺或甲亚胺特性基团的一类有机化合物，早期的研究一般为缩胺类席夫碱。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
