不连续函数

The function of the system equations is not continuous in real number set because of the existence of the "state deep trap".

本文研究扩展有限元方法，通过改进标准有限元的单元逼近函数，使之能够表达单元内的几何不连续，从而实现切割和断裂的模拟。

In the case of time discrete model obtained by traditional scheme, for the discontinuous switch, the cost function become piecewise due to the discretized error.

在离散情况下，对不连续"开关"，离散使代价函数出现有限个间断点。

This method can overcome the defects of traditional analytical optimization methods: they are hard to suit the conditions of discontinuous objective function and disconnected constrained domain. At the same time, the quantities measured by PMU can fully give play to maximum advantage while limited PMUs are placed.

该方法克服了传统解析优化方法难以适应不连续目标函数和不连通约束域等情况的缺点，同时，在配置有限PMU的情况下使PMU量测量发挥最大效益。

To deal with this, Evolutionary Computation is introduced into the discriminative training of the models.

另外，直接基于最小分类错误的训练方法由于目标函数的不连续、不可导，也无法采用梯度方法。

2The speed of creating random series used irrational fraction arithmetic was faster than that of multiplicative congruence arithmetic. The correlative value of random series almost was zero.(3) Regarding not harm the images quality as the premise, the speed of FM screening was heightened.

主要结论：利用所建立的条件半色调函数进行图像加网，操作简单、控制精确，使发生阶调不连续处的密度差平均减少到0.01275，明显改善了调幅加网印品的质量；(2)无理数取尾法产生随机数的速度快，数列间几乎没有相关性；(3)在不损失图像质量的前提下，提高了调频加网的输出速度。

In order to solve the problem effectively, a GA-based strategy is given after the complete analysis of the features of GA, which is very efficient to solve large-scale, non-linear, uncontinuous and multiple optimums optimization problems.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
