顶曲线 meaning in Chinese

summit curve

In the paper the initial iocation and dimension of step are studied from which we get the conclusion tha the energy dissipation is highcr if the initial location is at the curve section of l / 2 height of the spillway top and the dimension gap of neighbor step is bigger , the energy dissipation is higher
通过对阶梯溢流坝的过渡阶梯的起始位置和具体尺寸的试验研究。得出过渡阶梯的最佳起始位置约在坝顶曲线段1 2高度处且相邻阶梯的尺寸相差较大时，所得的消能率较高。
Abstract : this paper takes the manufacturing of non - circular gear as an example to analyze the non - circular gear ' s tip curve error influence upon it s contact ratio which is manufactured by involute cylindrical shape cutter , and it provides a theory basis to control strictly non - circular gear ' s contact ratio
文摘:以非圆齿轮插齿加工为例，分析了利用渐开线圆柱插齿刀加工非圆齿轮时齿顶曲线误差对非圆齿轮重合度的影响，为严格控制非圆齿轮副的重合度提供了理论保证。
