The CFD method was applied to calculate and simulate the form and action process of the cavitation at the representative character of the cavitation erosion on the surface of the hydraulic turbines.Some argumentation was presented that micro jet impacted the wall with a certain degree when bubble collapsed with the result that the maximal strain of the wall annularly distributed the local of the boundary touching the micro jet.Cavitation was gradual to develop regionally at the mode of chain reaction and di...

针对水轮机叶片表面气蚀的典型特征，利用CFD方法进行仿真计算，模拟气蚀形成和作用过程；根据模拟计算结果提出了新观点：空泡溃灭发生微射流以一定的倾角冲击壁面，壁面材料产生的最大应变在流束边界局部区域，呈环状分布；空泡气蚀在局部区域是渐进的，以"连锁反应"形式扩展，具有一定过流环境的分布特征；典型的冲蚀缺陷形貌是空泡气蚀在不同阶段的产物。

设计以安全、经济合理、美观为原则，进行结构选型和各楼层结构平面布置，用PK软件布置好结构平面后再转到AutoCAD上进行局部修改；采用手工计算设计老师指定的楼梯和楼板，并用PKPM软件计算指定楼板，与手工计算的楼板进行比较，取二者之长绘制成施工图；手工计算老师指定的框架荷载，建立好PKPM计算框架程序模型，用PKPM计算框架内力并输出文件结果，把PKPM计算得到结构配筋图转到AutoCAD进行局部处理；从PKPM得出的框架构件内力组合，选择三组最不利的组合作为基础设计资料，进行手工设计基础，并用AutoCAD绘制得出基础详图及配筋。

The local wartheory developed in the former Soviet Union,while stressing the imminence of anuclear war,focused on the need to prepare for both nuclear and conventional lo-cal wars.

前苏联的局部战争理论，在准备打火箭核战争的历史条件下萌芽，在核战争和常规战争并重的军事战略中形成；冷战后的俄罗斯，确立了以应付局部战争和地区冲突为侧重点的军事战略。

Even a small scratch or a local sheet metal parts were injured, the traditional practice of baking sheet to be re-done the entire finish, to avoid the so-called chromatic aberration, but this way, the original car's high-temperature paint will lose its significance, But in the construction of a new pump with disabilities spectrum operations, do not have to worry about paint finish color, but only to repair damage to local area, and will not damage surrounding paint, but also will become the old and new exterior color is the perfect combination of the same.

即使是一个小刮痕或是局部钣件受伤，传统的钣烤的做法都要重新做过整个漆面，避免出现所谓色差问题，但是如此一来，原车的高温漆面就失去意义，但是在全新的搏士光谱施工作业中，根本不用担心漆色色差，而且只针对受损局部区域修补，并不会破坏周边漆面，又能将新旧漆色变成一致的完美结合。

The proposed algorithm comprehensively considers the effects of local area average brightness of the background and space complexity on visual resolution. In order to judge whether the variance of gray is effectively percepted or not, the just noticeable difference is derived. The changes in the number of perceptible pixels between the original image and the enhanced image can be calculated by use of JND parameter. Thus quantitative results to assess the quality of enhanced images are obtained.

算法综合考虑图像局部区域的背景平均亮度和空间复杂度对视觉分辨力的影响，导出了用于判断局部灰度级跃变是否被有效感知的重要参数―临界可见偏差JND，并利用此参数分别计算出图像增强前后有效感知像素数的变化情况，从而定量地给出图像增强质量的评价结果。
