计算时间

Compared with standard Crank-Nicholsonscheme in the same computational time and resource, the method has two characteristics: small truncation error of in the transverse direction and high accuracy. It is a useful tool for designing optical waveguide devices.

与标准格式的有限差分光束传播法相比，该算法在几乎不增加计算时间和计算机内存资源的情况下，结合了道(来源：122eA22BC论文网www.abclunwen.com)格拉斯格式的有限差分光束传播法截断误差小和宽角多步法所具有较高精度的优点，是光波导器件理想的数值模拟工具。

He had seen 13 suns in the Eskimo way of keeping time.

按照爱基斯摩人计算时间的方式，他已经看到13个太阳了。

You can probably skip the detailed calculations of the running times of raising to powers and of the euclidean algorithm; just say what the final estimate is.

比如你可以把计算时间的估计这些内容删掉，只讲最后的结果。

In this algorithm scheme, the multiplication of inverse matrix and a matrix is executed by the matrix triangular factor decomposition and back-substitution for the solution.

该算法保留了原方程组系数矩阵的稀疏存储方式和稀疏矩阵的运算规则，减少了计算时间和运算过程所需要的存储空间。

In order to reduce the computational complexity, this thesis proposes three fast algorithms to select the block mode and to reuse the motion vector information.

画面内模式的选择，由於每次做一次区块选择必需要做9种模式，在这9种模式中，选择出所要的模式，因此会浪费计算时间。

The first part includes five sections as follows:§1 Origin and development of the four color problem;§2 Plane graphs and maps;§3 Planarity testing of graphs;§4 Maximal planar graphs;§5 Duality.

他们的基本方法是在所有平面图的可约构形中找出一个不可免的完备集。占旧计算时间12u多个小时。这样的工作量是

Second, based on the proposed weak formulation, we investigate the numerical solutionsof the time fractional diffusion equation.

基于上述弱解理论，我们计算时间分数阶扩散方程的数值解。

The one year period referred to in the preceding paragraph shallnot be subject to suspensio n or interruption, provided however that timeshall not run during the period that the lienor is le gally prevented fromarresting the vessel.

前款所述一年期限不得中止或中断。但在行使留置权之人依法被阻止扣押该船期间，不得计算时间。

When up to 31th harmonics are analyzed, the calculation time is only 1/82 of theat by the classical Gaussian elimination method.

对于一个周期值事先不知道，在一个周期内有100个采样点的非整周期采样，这个近似方法可使谐波分析的准确度由一般的DFT的10〓量级提高到10〓量级；当分析至31次谐波时，计算时间约为经典高斯消去法的〓，将能满足实际的工程需要。

From then on, people were able to measure time and determine seasons based on the position and length of the gnomon's shadow.

从此，人们便通过观测圭表上日影的长短变化来计算时间、测定季节。

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%.
