模型

In the middle of 20 century, agreat lot of scholars simulated the relation between the velocity of action potentialpropagated along a myelinated fiber or an unmyelinated fiber and the fiber diameteror the temperature. The results were according to the experimental results. But by far,there are lacking in the quantitative analysis of the velocity of action potentialpropagated along a myelinated fiber and an unmyelinated fiber.

本文首先分析了动作电位在无髓神经纤维上的传递机制，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，结合电缆模型与 H-H 模型，建立了动作电位传递期间神经纤维的等效电路模型，并在此基础上推导出计算传递速度的公式，对其进行了验证。

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。

Those eminent financial institutions needed elaborate theories, models, whizz kids and tens of thousands of MBAs. Mr Madoff did it all by himself, and he's an old man, too.

这些著名的金融机构需要更详细的理论，模型，精明的家伙们和成千上万的工商管理硕士。，Mr Madoff自己一个人做了所有，他是的一位老人了。

To investigate the role of transmural dispersion of repolarization and cardiac restitution properties in arrhythimogeneity in LQT2, we observed the effects of d, 1-sotalol, hypokalemia and calcium channel blocker on TDR and cardiac restitution properties at different basic cycle length by using the arterially perfused rabbit left ventricular wedge preparation.

为探讨心室跨壁复极离散度和动作电位时程恢复性质的变化在LQT2室性心律失常发生中的作用，笔者采用冠状动脉灌注的兔左室肌楔形组织块制备LQT2模型。标本随机分四组：对照组；LQT2模型组（100 mol/L d，1-sotalol灌流）；模型+低钾(3 mmol/L)组和模型+低钾+维拉帕米(2 mol/L)组。

The direct weight address mapping techniques are used in this model and algorithm, and the relation between the inputs and the weights is established by taking the inputs of training samples as their weight address, and the corresponding weights are found for any inputs by taking it as similar weight address, and the accurate outputs are obtained by the associable insertion algorithm.

模型、算法采用直接权地址映射技术，以训练样本的输入为地址，建立起输入与权重的关系。任意输入作为相近的权地址，即可找到对应的权，经过联想插补后可获得高精度输出。
