A new particle swarm optimization, PSO with bounded mutation operator, was developed. In contrast to the original PSO, in this algorithm, PSO with bounded mutation operator would make the particles redistributed cquably close to boundary when place of particle exceeds feasible region during iteration.

提出了一种新的粒子群优化算法——带边界变异的PSO，其原理是：在迭代的过程中，当粒子的位置超出可行域时，带边界变异的PSO让粒子的位置重新均匀分布在边界附近；当粒子的速度超出可行域时，则使其均匀分布到整个可行区间，而不是像原始PS0那样在这2种情况下都只是简单地取边界值。

After analyzing the soil stress, flexure moment data of central section of the sheet, and the flections data of two kinds of holding sheet models which are different on span, the paper gets the horizontal and vertical soil stress distribution rules and compares the result of the exam with calculating result of classic soil stress theory.

对3个已知取样深度和3个未知取样部位的吉林陨石样品的热释光研究表明，其自然热释光值具有宇宙成因核素含量相似的性质即深度分布效应，随着样品距离表面位置的增大而降低，这表征了母体暴露期间宇宙射线的分布状况。

在Hsu R L的统计模型的基础上，提出了一种自适应检测算法，该算法根据肤色值在非线性变换后的色度空间的二维直方图分布，自动确定肤色模型的位置，从而能更加准确地描述肤色在一幅图像中的分布情况。

The simulated radial distribution function and diffusion coefficient also accord with experiment basically.

模拟获得的径向分布函数和扩散系数的值与实验基本吻合，分子间作用能分布也与文献报道的趋势一致。

This regression problem is dicult for several reasons: large number of examples, large number variables (most of which are discrete and multi-valued), non-stationarity of the distribution, and a conditional distribution of the dependent variable which is very dierent from those usually encountered in typical applications of machine learning and function approximation.

这个回归问题是，邸邪教组织有多少个原因：大量的例子，大批变量（其中大部分是离散和多值），非平稳性的分布，以及有条件的分布因变量，这是非常邸erent从这些一般遇到的典型应用机器学习和函数逼近。

The rate of fall is dependent on the continuity of the scale function in time domain. Furthermore, it relates with the multiplicity of zero point at ω=π of the amplitude spectrum of the low pass filter. The distribution of zero points was investigated thoroughly. From the above statement, the dominant interval is deduced to be [0, 2π].

衰减性取决于尺度函数的连续性，进一步它与低通滤波器在ω＝π处零点重数有关；详细讨论了零点的分布及其重数；由零点的分布和衰减性推出尺度函数的幅值谱主导区间为[0，2π]；ω＝0处极大值性态与低通滤波器在该处性态相同。

To solve the problem that the-spectrum estimation performance based on covariation under the-stable noise environmentbecomes obviously worse when the distribution parameter is small,a method of fractional low-order covariance spectrum estimation was proposed.

针对在分布参数值较小时稳定分布噪声下基于共变的谱估计性能较差这一问题，提出了一种分数低阶协方差谱估计方法。

It can get the three-dimensional profile of the object surface effectively. Because of the cragginess of the three-dimensional surface when sine grating is projected the image of the sine grating is modulated and the modulated image is taken by a CCD camera with an angel compared to projecting direction. After the phase shift measuring method, the phase is gotten. Because the phase is calculated by the phase shift measuring ranges from –π to +π it isn't continuous. The phase unwrapping is necessary to recover the continuous phase about the object shape.

这种方法采用结构光照明，将正弦光栅图像投影到被测物体表面，用与投影方向成一定角度的CCD摄像机获取受物体表面面形调制的变形光栅像，根据数字相移算法计算出相位分布，由于从相移计算的相位被截断在反三角函数的主值范围内，因而是不连续的，必须通过相位展开恢复出连续相位分布，由相位－高度关系最终求出物体轮廓的三维数据信息。

在k-means算法基础上，提出利用平均相对偏差对数据的维分布密集度进行度量，并根据空间分布的密集度动态地给属性赋予权值。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
