计算时间

This makes the suggested standard of harmonic analyzer feasible for practical use.

但这个方法用传统的处理方法（高斯消去法或迭代法求矩阵的逆）付诸实施时，将会碰到计算时间很长的困难，因而使测量的实时性受到很大的妨碍。

In this thesis, an improved algorithm for 2D shape matching based on Modified Hausdorff Distance is proposed. Hausdorff Distance is used to measure the degree of similarity between two objects to make matching more effectively.

传统的模板匹配是基于相关准则的，当两个形状具有平移、旋转、尺度变化时，需要极长的计算时间，使得该方法难以得到实际使用。

We should count time by heart-throb.

我们应当按心脏的搏动来计算时间。

We should count time by heartthrob.

我们应当按心脏的搏动来计算时间。

The mild-slope equation with current effects is reformulated to an inhomogeneous Helmholtz equation. Applying the conventional boundary element method to this inhomogeneous equation, the inhomogeneous part will result in a domain integral which makes the computation complicated and messy. To improve this drawback, the DRBEM is adopted to transform the domain integral to boundary integral.

首先将含水流效应之缓坡方程式重新整理为非齐次之Helmholtz方程式，再利用Green公式改写为积分方程式，但利用一般传统边界元素法解析时，将存在一领域积分项，使得边界元素法显得繁杂且不完美，为改善此一缺陷，本文乃应用双互换边界元素法之技巧，以节省大量之数值计算时间。

The proposed encoding does not include the information of workers and machines, so it is easily to intercross and mutate between chromosomes and spare computational time.

本算法采用的遗传编码不含工人和机床设备的信息，使得染色体的交叉和变异容易操作，节省了计算时间。

It would have been possible now to keep count of the passage of time, if he had felt any interest in doing so, since he was being fed at what appeared to be regular intervals.

如果他有兴趣的话，现在有办法计算时间了，因为他们定时给他送吃的来。

The human brain keeps time, from the flicker of milliseconds to the languorous unfurling of hours and days and years. It's the product of hundreds of millions of years of evolution.

我们人类的大脑可以计算时间，从一闪而过的毫秒到漫漫长长的几个小时、几天、几月、几年……这一思维功能是人类数亿年来不断进化的成果。

In this paper, the analytical formulations for every reflection point's Z coordinate are deduced by using Fermat's principle and law of reflection in the system of cylinder and cone.

以圆柱和圆锥二阶系统的反射寻迹为例，结合费马原理和反射定律，推导出各反射点Z坐标的解析表达式，从而减少了寻迹方程中未知数个数，使计算时间显著缩短，也提高了结果精度，文中给出了应用实例。

The sort dominates computational time, so anything that makes the sort more efficient is a win in the limit case.

占主导地位的排序计算时间，因此任何使排序更有效的是a比赛中，案件限制this限制是迅速达成）。

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）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
