But it has the shortcomings of longer calculation and easily getting into local minimum.

但它的计算时间长，易陷入局部极小一直是它不易克服的缺点。

To shorten the computational time again, the intermediate variables of Riccati transfer matrix method used in vibration mechanics are improved without changing calculation precision and memory storage.

在Riccati变换时，选择了不同于振动力学Riccati传递矩阵法的合适中间变量，不扩大存储量的前提下进一步减小了计算时间。

But the former's calculating time and memory utilized for former model is far less than that of latter.

而前者的计算时间和内存空间比后者大为减少。

Finally, the proposed method is applied to several meshed distribution networks and the results are compared with NR method, both in terms of speed of convergence and computation times.

文章的最后，在收敛次数和计算时间上，与传统牛顿法做了比较，验证了算法的优越性。

As early metazoan Health or pushing the issue, and your menstrual said to have relations, normal menstrual always your computing time than later, you may defer Health baby.

至于提前生还是推后生的问题，据说和你的月经有关系，平常你的月经总是比计算时间推后的话，你就有可能推迟生孩子。

The modulo map which authors adopt can not only extend and collapse image but also save computation time greatly.

采用的模运算不仅具有像Arnold等变换对图像进行拉伸和折叠的作用，而且可以在很大程度上节约计算时间。

Considering the actual need of hydro-structure design, one algorithm for drawing isoline map or nephogram is proposed in this paper. Compared with other algorithms, this algorithm is easy to implemente, and the increase of series of isoline will not result in the observable increase of the time for computing the isoline.

此算法依靠单元共边共点的特性保证等值线或云图的连续性，相对等值线追踪算法而言，此算法简单易行，而且实际测试结果表明等值线级数的增加不会导致其计算时间的显著增长。

However, with more nodes the analysis time is also increased.

然而，更多的节点将导致计算时间的增加。

At the same time, the time taken to solve the system of normal equations for the least-square method is also reduced by using matrix updating techniques associated with Broydens quasi -Newton method.

同时运用拟牛顿矩阵校正技术解最小二乘方程组也减少了大量的计算时间。

In this implementation, the evolutionary algorithm is hybridized with the simulated annealing algorithm and the hill climbing heuristic. The main aspects are as follows. The Metropolis criterion of the simulated annealing algorithm is introduced to select the offspring in order to make the algorithm more effective to escape the local optimum. In terms of the hill climbing heuristic, the local normal perturbing mutation operator based probability selecting is developed to enhance the local searching of the algorithm.

其主要工作是将进化算法与模拟退火算法及爬山方法相组合，引入模拟退火算法中Metropolis接受准则选择子代，提高算法跳出局部最优解的能力：借鉴爬山方法思想，构造了基于概率选择的局部正态摄动变异算子，以强化进化算法局部细搜索能力；同时进化算法以多种群方式实现，在降低计算时间的同时提高算法收敛到全局最优解的概率。

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％。
