查询词典 arc cotangent

Type IB: Isocline is convergent towards inner arc at a right angle to the fold.

根据等斜线的收敛层度，再细分为三个亚型：IA型：等弧线向内弧强烈收敛，各线长短判别极大，内弧曲率远大于外弧曲率，为典型的顶薄褶皱；IB型：等倾斜线向内弧收敛，并与褶皱面垂直，各线长短大致相等，褶皱层真厚度不变，内弧曲率仍大于外弧曲率，为典型的平行褶皱；IC型：等斜线相内弧轻微收敛，转折端等倾斜线比两翼附近的要略长一些，反应两翼厚度有变薄的趋势，内弧曲率略大于外弧曲率。

The curvature radius was derivated and the contact stress of the three-arc-sect isometric type surface was calculated through the elastic dynamics theory.

应用弹性力学理论，推导出接触点的曲率半径，对三弧段等距型面联接进行接触应力计算。

In the program the Newton-Raphson's method is used to iterative computation; and the method of either the cylinder-arc-length or the minimum residual displacement is adopted to control the iterative process.

在分析非线性静力和动力有限元计算方法的基础上，本文采用修正的Newton-Raphson方法进行迭代计算，并采用柱面弧长法和最小残余位移法控制迭代过程，编制了一个适合于杆件体系结构的有限元分析程序，结构可以按桁架、刚架或梁杆组合体系分析。

It is true that Dusk's Classics and Plebeians' Jocosity has some correct statements, but there arc many pails running counter to the academic principles, for instance, making sweeping criticisms, self-contradiction, inadequate evidence, spontaneous remarks, random criticism, and fallacious reasoning.

尽管《经典的黄昏与庶民的戏谑》中也有一些正确的说法，但从总的情况看，却存在着诸多背离学理的地方－或以偏概全，或自相矛盾，或不符事实，或证据不足，或任性发挥，或随意指摘，或强词夺理。

The results showed that the fracture toughness of the weld of HFW pipe was lowest.The value of absorbed energy of HFW weld was closely related to the heat treatment process.But the fracture toughness of fusion zone of submerged-arc welded jointer,its microstructure was coarse granular bainite,and was lower than the other locations of heat affected zone;and with the increasing of steel strength,the effect of welding heat cycles on the pipeline steel became stronger,and form coarse microstructure in fusion zone leading to decrease fracture toughness.

结果表明，高钢级管线钢高频焊接焊缝处的断裂韧性最低，其冲击功大小与热处理工艺密切相关；而埋弧焊接热影响区断裂韧性在熔合线处最低，其主要原因是此处的组织为粗大的粒状贝氏体，而且强度越高焊接热循环对管线钢的作用越强，在熔合线附近更容易产生粗大组织，使断裂韧性降低。
