The velocity distribution of the numerical simulation and the theoretical equations calculation are compared on the condition of axial symmetry.

结果表明，在轴对称条件下，对数模、理论计算的速度分布进行对比分析，证实了旋涡流场不仅是径向的函数，而且还是轴向的函数。

Changing the form of coordinate axis could observably improve the quality of fingerprint, such as logarithmic coordinate axis or axis break.

适当地调整图谱的坐标形式，如采用对数坐标形式或采用两段不同的单位坐标值形式等，可显著改善指纹图谱的质量。

For millions of fans, he will always be Superman.

In the pricing of a Bermudan CDSwaption, by assuming that the forward CDS credit spread are log-normally distributed, Tucker and Wei (2005) illustrate some of their applications and propose a binomial tree valuation model.

而在百慕达式 CDSwaption 的评价中，Tucker and Wei (2005)提出了二元树状模型，在 CDS 远期信用利差之分配为对数常态分配假设下得到近似解，然而在此假设之下，只能捕捉到远期信用利差报酬率分配之一阶动差和二阶动差的性质以致於评价的结果缺乏弹性。

When seismic wavelet is in non-minimum phase , we can make it have smaller phase by doing exponential weighting . As for nonwhite noise problem of reflection coefficient , we may employ logarithmic power spectrum to estimate the autocorrelation function of seismic wavelet , then obtain seismic wavelet and deconvolution opera .

当地震子波为非最小相位时，可利用指数加权方法使之小相位化；对于反射系数非白噪声问题，本文提出利用对数功率谱来估算地震子波的自相关函数进而求取地震子波以及反褶积算子的方法；对于理想的期望子波，本文采用"宽带雷克子波"作为期望输出子波。

IN 1996, David Colander of Middlebury College, in Vermont, expressed his dissatisfaction with decades of economics by invoking a lofty analogy.

It is based on the difficulty of computing the discrete logarithm modulo for a composite number and the factorization problem of large integer.The size of the group signature and verification time of the group signature are equivalent to that of an individual signature.

该方案的安全性是基于求离散对数和RSA大整数因式分解的困难，其群签名长度和群签名的验证时间只相当于一般个人签名。

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）。
