查询词典 hypothesis

In this paper, we first analyze the mechanism of action potential propagated alongan unmyelinated fiber, and present a hypothesis that the velocity of transmembranecurrent is the equivalent of the propagation velocity of action potential. Then usingthe H-H model and the cable equation we obtain the formula of the velocity. Insuccession, we apply a similar method to analyze the mechanism of action potentialpropagated along a myelinated fiber. Using the McNeal model and the CRRSS model,we obtain the formula of the velocity.

接下来，应用与无髓鞘神经纤维相类似的方法，分析了动作电位在有髓鞘神经纤维上的传递机制，同样得出了可用跨膜电流的移动速度来等效动作电位传递速度的结论，利用 McNeal 模型和 CRRSS 模型，建立了有髓神经纤维在兴奋传递期间等效电路模型，并推导出了速度的计算模型。

Our hypothesis is that (1) many strains of rats simply cannot mount a sufficiently vigorous destructive immune-response to outstrip the liver ' s relatively great capacity to protect itself from immune-response damage and that (2) the systemic unresponsiveness observed is due to concentration of the recipient ' s donor-specific lymphocytes at the site of the liver transplant.

我们的假设是：（1）许多种老鼠纯粹就是无法发起一场足够强的摧毁性免疫应答（immune-response），以压倒肝脏相对较强的保护自身免遭免疫应答损害的能力；（2）所观察到的系统性无应答状态，是由于受移植者的供者特异性淋巴细胞集结在肝脏移植物所在的部位所致。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
