A meso mechanical analysis has been conducted on a hot-rolling steel of 16MnR toinvestigate the effect of the elongated pre-damage voids on the subsequent damage evolution and fracture process under the maximum normal stresses with various directions. The analysis results show that, when the elongated voids due to the decohesion of the inclusions from base material are loaded subsequently, the local high stress and strain concentration around the voids and their interactions promote the growth of voids.

对热轧钢中的长条形初始损伤孔洞承受不同方向最大正应力时的后续损伤演化和断裂过程的细观有限元力学分析研究表明：热轧钢中的长条形夹杂物与基体剥离后形成的长条形孔洞在后续加载中，其周围产生的局部高应力应变集中及其相互作用，使孔洞长大。

A method of path planning based on rolling windows with function of normal distribution density for mobile robot was presented in this paper.

在原有滚动窗口路径规划方法基础上，提出基于正态密度函数的滚动窗口路径规划方法。

The mountains and the colors are not infected vicissitudes of life are still stubborn with green green; silly eastward of the river has not only failed to become like a mirror-like bright and quiet, but autumn in the rolling dry moving slightly turbid; river plants desolately miserable miserable all day Wangziningmou Although there is no yellow autumn bleak Akigusa decay, the situation could be a cheerless place a layer of more people unnecessarily autumn coolness.

群山并没有染上沧桑的颜色，依然固执着苍翠的青绿；痴心东流的河流不但没有变得如镜般明亮宁静，反而在连绵的秋雨中稍显浑浊燥动；河边的水草凄凄惨惨，终日枉自凝眸，虽无秋风惨淡秋草黄的衰败，可冷冷清清的境地更使人徒添一层秋的凉意。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
