The model needs to include a mechanism for passing root objects to each iteration that can be used to store and retrieve objects that have a lifetime of Retain Thread Group or Retain Thread. 模型需要包含一种机制,将根对象传递给用于存储和检索生存期为RetainThreadGroup或RetainThread的对象的每个迭代。
In particular, it can help you root out the pitfalls of using the JNIEnv with the wrong thread and using critical regions incorrectly. 特别是,它可以帮助您确定在错误线程中使用JNIEnv以及未正确使用关键区域的缺陷的根源。
This tracing starts with the root set, which consists of internal structures such as thread stacks and global references to objects. 这个跟踪以根集开始,它由一些内部结构组成,比如线程栈和对象的全局引用。
The extraction of a root of a quantity. We think this thread has broken off. 开方,求一个数的方根我们认为这根线断开了。
The root of the external thread or the crest of the inner thread. 大径指过外螺纹牙顶或内螺纹牙底的圆柱面直径。
Through metallographic analysis of the material, microstructure change and deformation mechanism of crest, flank and root of the thread along the layer depth direction were obtained. 结果表明,牙顶处金属材料受到丝锥棱齿的压力相对较小,并且金属流向牙顶两侧上方的区域时受到的阻力最小;
The results show that the non-normal fracture of the bolt is caused by generation of the crack in the root of thread before the tensile test; 结果表明,非正常断口的形成是螺栓在拉伸前螺纹根部就存在裂纹。
Result indicates that surface decarburization in thread root of bolt and microcrack in plastic deformation layer of thread surface are the main causes to reduce seriously the strength of bolt and result the bolt rupture failture. 结果表明,螺栓的螺纹根部表面脱碳,螺纹表面塑性变形层中存在微裂纹,表面脱碳和微裂纹严重降低了螺栓的强度,导致螺栓断裂失效。
By optimizing the radius of rounded corner at the root of thread and the structure of screw nut, and by changing the diameter of the root of thread, the concentrated stress was reduced, and stress distribution was improved for higher fatigue strength of the screw bolt. 通过优化螺栓螺纹根部圆角半径和螺母结构、改变螺纹根部直径的方法,缓解螺纹根部的应力集中,改善应力分布,实现提高螺栓疲劳强度的目的。
An analysis was made of stress concentration at the root of screw thread by finite element method. 应用有限元接触分析方法,研究钢轨螺栓螺纹根部的应力集中。
Finite Element Analysis of Stress Concentration at the Root of Screw Thread of High Strength Bolt 高强度螺栓螺纹根部应力集中的有限元分析
Assessed by production application experiment, the wear of PCD thread mill cutter is analyzed. Based on wear mechanism, the wear root cause of PCD thread mill cutter is found. Single piece processing cost is determined. 通过生产应用试验,分析了PCD螺纹铣刀的磨损情况,根据磨损机理分析出PCD螺纹铣刀磨损原因,并确定PCD螺纹铣刀的单件加工成本。
