life curve meaning in Chinese
生命曲线
寿命曲线
Examples
- Generalized fatigue constant life curve and two - dimensional probability distribution of fatigue limit
广义疲劳等寿命曲线与二维疲劳极限概率分布 - It shows that the damage parameter is more suitable for composite multiaxial fatigue investigation than the traditional strain versus life curve and the predicted fatigue lives have a good agreement with the tested values
结果表明：与传统的应力-寿命预测曲?相比较，新的疲劳损伤参量更适合于复合材料的多轴疲劳研究，计算结果与实验结果吻合较好。 - 5 component fatigue life curve ( p - s - n curve ) is used in fatigue life analysis . the thesis provides fatigue life whose possibility is 95 % or 50 % . the analysis results of fatigue life and weak elements agree with fact
本论文分析了该泵车可靠度为95和50的疲劳寿命，分析结果与泵车长期使用总结出的疲劳寿命基本吻合，且分析结果疲劳寿命薄弱部位在泵车实际工作中基本都产生过疲劳裂纹。 - The existed material fatigue performance test curves are dealt with and analyzed , and the non - dimensional stress - strain curve , tangent modulus factor curve and fatigue life curve are drawn based on the experiment data , and these three non - dimensional parameter curves are used to find the inherent rules that the test curves can be replaced each other to some extent . it can be concluded that if the common character and system error of these materials are found , the test curve of a certain material can be used for reference by another material . this is a simple approach about fatigue life estimate and is engineering practical
对已有的材料力学疲劳性能试验曲线进行分析整理，利用试验数据绘制了相对应力应变曲线、切线模量因子曲线和疲劳寿命曲线，利用这三种无量纲参数曲线发现了其中存在的规律性，即在某种程度上实验曲线可以互相取代，并用试验数据对此进行了讨论，并由此推断，如果找出材料彼此的共性或彼此之间的系统误差就可以将一种材料的试验曲线供其它材料参考使用，这是一种估算材料的疲劳寿命的简便方法，对工程而言具有实用性。 - The useful life curves of gan - based blue led with al2o3 and sic substrate is fit single exponential function [ i = i1 + i2exp ( - t / ) ] . fron this function , we could get aging information of led about stable inteneity 1 , decay intensity i2 and decay time . the novel method of evaluating aging properties of leds was put forward
用单指数函数拟合了发光二极管的光衰减曲线[ i = i _ 1 + i _ 2exp ( t / ) ] ，这个关系式可以给出三个信息：稳定光强、衰减光强、衰减速度，提出了更加合理的评价led老化性能的方法。
