无扭力

This research sets up a four-stroke unthrottled engine model equipped with electromagnetic valves, In this research, we analyses the influence on the engine volumetric efficiency, house power, torque and fuel comsumption by changing the opening and closing timing of the intake valves when the engine rotates in low, medium and high speed.

本研究建立配有电磁式气阀的四行程多缸无节流阀引擎动态模型，分析引擎在低、中、高转速下，改变进气阀开闭正时对引擎容积效率、马力、扭力以及燃油消耗率的影响。

The headframe structure studied is composed of two trusses in the direction parallel to the hoisting load, and two rigid frames in the perpendicular direction.

按桁架框架型井架在断绳荷载作用下，考虑扭力计算与不考虑扭力计算，其结果，平行于钢丝绳力方向的桁架内力可减少10～20%左右；垂直于钢丝绳力方向的框架内力则增加100%(即，若不考虑扭力计算框架时无内力)。

After 2～4 weeks, the amounts of the osteoblast and chondroblast in medullary callus in SMC group were more than group of CP, IN.

生物力学时间断面研究结合体外DEXA测量结果表明：术后2周SMC组和IN组刚度系数、面积比率、扭力刚度、最大扭力无显著性差异，CP组略差。

According to the results of this study, the ultimate strength of pin-bone interface increased as the moment arm decreased and torque increased. When the pin-bone angle approached 90°, the ultimate strength was the largest and as the angle decreased, the ultimate strength decreased. There was no significant difference between rigidity and torque, but rigidity decreased as the skull-bone angle decreased.

结果发现钉骨界面的极限强度在头圈距离颅骨的力臂短时较高，且随著所用扭力的增加而增加，当头钉与头骨表面的夹角成垂直时最强，随著夹角越趋锐角而渐减，钉骨界面的刚性与扭力并无明显关系但与夹角有关，夹角垂直时刚性最高，而后随著夹角渐趋锐角而递减。

Front McPherson strut and rear torsion beam suspension were doing its job beautifully over pot holes and broken road.

前麦花臣式后扭力梁式悬挂系统在坑洼路面上仍轻松胜任将车身的摇晃感觉降到最低甚至无感觉。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
