The large displacement movable boundary in chemical reaction flows was simulated by the combination of spring method and local remeshing method. Spring method was sufficient for relative small boundary displacement; local remeshing method was used to deal with large boundary displacement.

采用弹簧方法和局部网格重构法相结合的动网格技术实现了快速、优质地模拟化学非平衡流场中边界的大位移运动，为了克服网格变形或重构引起的质量不守琚A采用积分重映求取新网格上流场状态参数。

In this paper, we have deduced an iterative algorithm with relaxation parameter from the successive over relaxation method, which not only deduce the necessary of computation time and memory space but also is propitious to overcome the sensitivity of reconstructed images to incomplete noisy data.

从解大型线性方程组出发，由逐次超松弛法(Successive Over Relaxation， SOR)推导出一种带有松弛因子的迭代法。与 SOR 法相比，该算法不仅大大降低了对计算时间和内存空间的需要，而且有利于克服重建图像对不完全噪声数据的敏感性。

Compared with ENOR and SMOR, the only two existing MOR analysis methods for RCS interconnect circuits, Block SAPOR overcomes their deficiencies of numerical instability or limited reduction accuracy.

Block SAPOR克服了现有的RCS互连电路降阶算法ENOR和SMOR存在的数值不稳定和降阶精度有限的不足，是目前为止最有效的二阶系统降阶技术。

The wavelet marginal analytical modeling wave impedance inversion is pickup characteristic parameters from seis.

基于模型的波阻抗反演虽然克服了厚、薄煤层计算问题，但因难以得到准确的高频部分，很多情况下反演结果的精度和分辨率往往不能满足地质预测的要求。

More importantly, this method can synthesize a facial image with mouth opened and teeth showed from an unexpressive image with closed mouth. It outperforms other existing methods for facial expression synthesizing.

更为重要的是，该方法能从闭着嘴的中性表情人脸图像合成出具有张开嘴露出牙齿效果的人脸表情图像，克服了当前大多数人脸表情合成方法不能实现这一效果的不足。

But a unipolar world presented the US leadership with an immense, if not an insurmountable task.

但单极世界，介绍了美国的领导与一个巨大的，如果不是一个不可克服的任务。

Enzyme as a biological catalyst is very sensitive to the environment , physical, chemical and biological factors.In the other hand it is difficult to purify from the reaction products. What's more it can not make a continuous operation.All those astrict the reaction.Under this condition, enzyme immobilization was put forward and developed.

酶作为一种生物催化剂，对环境十分敏感，易受物理、化学和生物等因素的影响而失活，而且反应后混入产品，纯化困难，不能实现连续操作，这些难以克服的现象大大限制了酶促反应在工业中的应用，在这种条件下，固定化酶的概念和技术得以提出和发展。

Even excluding China, the absolute number of poor would be at their lowest level ever, finally overcoming the higher poverty created by the 1997 crisis, said Regional Vice President for East Asia and Pacific Mr.

即使不包括中国在内，贫困人口的绝对数字也将达到历史最低，我们终于克服了1997年金融危机造成的贫困增加的问题。

A new type of controller called PIDNN, which coalesces traditional PID and neural network together, is introduced in this paper. It overcomes these shortcomings mentioned and has better robustness.

本文提出了一种不同于用BP 网络调整PID 参数的新的融合方法：PID 神经网络控制器；该控制器不仅能克服以上缺点，而且具有很好的鲁棒性。

Theoretical analyses and experimental results show that PMF canretain the edge information of image and enter into the edge\'s concaves entirely.In the meantime,PMF has large capture range with few restrictions to initial curves.

该方法不仅能够保持车辆的边界信息，克服了传统外力场不能进入车辆图像凹部的缺陷，而且对初始曲线的约束较少。
