查询词典 friction band

By numerical integral of this model, the factors which affect the additional twist of yarn are analyzed, including the pressure in the profile tube, the coefficient of friction between the fiber band and lattice apron, the length of the suction slot and the curvature radius of profile tube.

通过对集聚区内须条的集聚过程分析，建立须条的受力模型，发现须条在集聚过程中会产生附加捻度，并且对影响须条附加捻度的各种因素：异型管开槽长度、负压大小、须条和网格套圈间的摩擦因数以及异型管的曲率半径进行了分析。

The DLC film deposited at substrate temperature of 100癈 shows the best integrated property with carbon content of sp3 (sp 3C) bonding state up to 40% which is two times more than that in the films prepared by Americans with the same method. Accordingly, the microhardness is up to 30Gpa, and friction coefficient and optical band gap decrease to 0.10 and 1.76eV respectively.

在HIPIB轰击材料表面方面，本文选择成分由C~(30％)和H~+(70％)组成、加速电压为250KV、脉冲宽度为80～100ns的HIPIB对高速钢(W6Mo5Cr4V2)进行表面辐照处理，研究离子束流密度和脉冲次数对高速钢微观结构和宏观性能的影响，探讨了HIPIB与材料表面相互作用的物理机制。

The DLC film deposited at substrate temperature of 100℃ shows the best integrated property with carbon content of sp〓 bonding state up to 40% which is two times more than that in the films prepared by Americans with the same method. Accordingly, the microhardness is up to 30Gpa, and friction coefficient and optical band gap decrease to 0.10 and 1. 76eV respectively. It is found that sp〓C content in DLC films decreases with the increasing substrate temperature in the process of film deposition, especially after 300℃.

当基片温度为100〓C时沉积的DLC薄膜的综合性能最好，此时沉积的DLC薄膜中sp〓C含量最高，达到40％多，是美国学者用同种方法所得结果的2倍；由于薄膜sp〓C的含量高使得其显微硬度达到30GPa，摩擦系数最小为0.10，光学带隙最宽为1.76eV。

Diamond has many outstanding physical, chemical, optical, mechanical, and electrical properties such as the highest thermal conductivity, the extreme chemical inertness, the highest known hardness, the lowest compressibility of known material, high in Young's modulus, low in friction coefficient, wide in band gap, and a wide optical transparency bandwidth.

中文摘要钻石拥有许多优异的物理、化学、光学、力学与电学特性，例如它拥有最高的热传导系数、具化学惰性、具有最高硬度、高杨氏系数与低摩擦系数、具有宽能隙与宽的光学穿透频域。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
