查询词典 asymptotic behavior

Simulation of heat transfer in the circular microchannel is conducted and it is revealed that heat transfer to the wall increases with the effect of axial conduction. The effect of thermal entrance is to increase the local Nusselt number. The smaller the velocity slip coefficient, the larger the asymptotic value of the Nusselt number.

对圆形微通道换热特性进行了数值仿真，结果表明，轴向热传导和入口效应增加了入口处的局部努塞尔数，速度滑移系数越小，局部努塞尔努塞尔数的渐进值越大。

By regression analysis of the obtained data, a relationship has been found between the bath depth and ingot height, which can be expressed by an exponential function, h(0,Y)=A e-B/Y, where A is the asymptotic value of the exponential function (when Y→∞hmax=A), B is a shape coefficient of the curve.

通过对已得数据的回归处理，找出了熔池深度h及锭高Y间的相关规律，得到h_(0，Y)=A·e_的指数函数关系，A是指数方程的渐近线，当Y+∞时h_(max=A是曲线形状系数。A和B均为重熔电流的函数，A=f_1，B=f_2，所以，h_(0，Y)=f_3。

Focusing the measurement of financial risk of extreme, this study empirically investigated the extreme risks of Chinese stock market based the theoretical researches of extreme value and relevant conclusions.This dissertation made an in-depth study on the type and nature of the asymptotic distribution of extreme value.

另外，我国正处在经济转型期，虽已初步建立起以国有商业银行为主体的商业性金融体系，但金融体制的市场改革依然远远滞后于其它经济部门，整体行业受政策影响较大，市场运行机制经常发生变化，金融体系风险非但没有降低，反而不断积聚，金融市场动荡加剧，作为市场经济晴雨表的沪深股票市场频频的巨幅涨跌即清楚地表示了金融体系的震荡状况。

It is shown that the far-field divergence angle of nonparaxial rotationally LG beams approaches to an asymptotic value of 63.435° as the initial waist-width to wavelength ratio w0/λ approaches zero,which is independent of the order.
