The load fatigue stress coefficient used in the load stress calculation for the porous concrete as undersurface of the cement concrete pavement were derived.

根据疲劳方程提出了以多孔混凝土作为水泥混凝土路面下面层应力计算的荷载疲劳应力系数，沥青路面基层层底拉应力验算的抗拉强度结构系数，建立了进行路面结构设计的轴载换算模型。

Microstructural analysis indicated that granular carbides existed in the steel of lower fatigue life prior to quenching heating, which remained undissolved during austenizing and remained in the quenching microstructure,resulting in lower fatigue life.

但调查发现，这些工作多数局限在弹簧钢常规力学性能方面，对抗疲劳性能的研究相对较少，而弹簧生产中则经常出现疲劳寿命达不到要求、影响因素却不清楚的问题。

Reliability evaluation methods are given in this paper on fatigue life of machine parts under uniaxial constant amplitude load.

众所周知，疲劳可靠性设计是应用概率统计理论进行零件抗疲劳设计的方法。

The brain controls the body," says Mark Kovacs, senior manager of sport science for the USTA and a Ph.D. in exercise physiology."If the brain senses you have fatigued a certain area of the body, maybe your serving shoulder, it senses you have fatigued the whole body.

Kovacs说"大脑控制了身体，如果大脑觉察到你身体的某些部位疲劳了，也许是你发球的肩膀，它会让你感觉到整个身体都处于疲劳状态。"

Of vermicular graphite iron is studied with the Uddeholm thermal fatigue testing method.

用Uddeholm热疲劳试验方法，研究了蠕化率对蠕铁热疲劳抗力的影响。

Under the conditions of fast heating, fast cooling and thermal cycling with larger temperature difference, it is concluded that(1)under appropriate strength and toughness, in creasing the vermiculating rate can enhance the thermal fatigue resistance of vermicular graphite iron;(2)increasing the vermiculating rate by a big margin can also enhance...

在快速加热、快速冷却以及较大热循环温差的服役条件下得出：(1)当强韧性相当时，提高蠕化率可提高蠕铁的热疲劳抗力；(2)大幅度提高蠕化率，尽管强韧性有所下降，但亦可提高蠕铁的热疲劳抗力。

The split between the two groups can hardly be papered over.
