查询词典 spalls

Cuttings are distinct from cavings, rock debris that spalls as a result of wellbore instability.

岩屑与由于井壁失稳而坍塌的落石及剥落的岩石碎片截然不同。

The oxide formed on NbSi2 at 1023 K consists of Nb2O5 and minor SiO2. The Nb2O5 is lose and nonprotective, which spalls from the sample during oxidation. The oxidation kinetics of all the NbSi2 samples at 1023 K follows a linear law. The oxidation rate is intrinsically determined by the reaction rate between the matrix and the oxygen in air, which in turn is determined by the exposure area of the sample.

无论是单晶还是多晶样品，氧化产物均为 Nb2O5和SiO2，生成的Nb2O5易剥落，样品的氧化动力学曲线均呈直线规律，证明NbSi2的氧化过程是一种本征无保护条件下氧元素与基体元素直接反应的过程。

Long time sliding causes fatigue failure of UHMWPE, a lot of big spalls are produced around the counterpart edge, debris from UHMWPE/PP blend does not show apparent increase with sliding time.

长的磨损时间导致UHMWPE疲劳破坏，产生大量的磨屑，而随磨损时间的延长，UHMWPE/PP表面的磨屑并无明显的增加。

It is suggested that the permissible crack width recommended in the current code may be increased, however, attention should be paid to the logitudinal crack which spalls and destroys the cover ...

本文建议，现行规范中横向裂缝宽度限值可以适当放宽，然而对造成混凝士剥落和损坏的纵向裂缝必须引起注意。

After unloading,both ends of the rod become free surface,which both play the role of stress unloading for the incident stress wave,and multiple spalls may occur.

加载端卸载后，杆处于两端自由面共同应力卸载作用下，可能出现多重层裂的现象。

According to the result, thepaPer gives some advices aboul the struture of the chamber.Through applying the CAD software, this paper not only searches after themethods and traits of I-Deas when it is used in solve complicated engineeringproblems. The paPer also offeres useful reference to the reliability design of engine"spalls, and settles a base for realizing the CAM of the engine"s parts.

本课题通过对大型CAD软件的开发应用，不仅探索出了I-Deas软件用于解决复杂工程问题的方法及应用特点，而且通过具体应用为发动机零部件的可靠性设计提供重要参考，也为实现发动机零部件的CAM奠定基础。

The results indicate that the spalling behavior of oxide scale is the result of the inner and outer stress together,during rolling,the oxide scale cracks under the growth stress and thermal stress,at the same time the oxide scale also mainly undergoes alternative shearing stress in the rolling zone,the oxide scale spalls,then the reason of stripspalling is also analyzed.

结果表明：氧化膜剥落过程是内外应力联合作用的结果，轧制过程中氧化膜在长大应力和热应力作用下开裂，在轧制区内氧化膜还因受沿轧辊圆周方向的交变剪切应力作用而剥落。

The composite coating followed by laser remelting and then aluminizing displays the best cyclic oxidation behavior, and scale spalls least; the composite coating followed by diffusion in 1200℃ for 6h does the next best.

激光重熔处理后再渗铝的复合镀层抗循环氧化性能最好，氧化膜剥落少。高温扩散处理后再渗铝的复合镀层次之。循环氧化200小时后，所有涂层内侧退化较轻。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
