查询词典 essential resistance

The results show that the microstructures of these three kinds of coating are different from those of the matrix (20 steel). The wear resistance of the flame spray coating is 4. 9 times that of the matrix. This is caused by the existance of hard noncrystal microparticals. The wear resistance of the coating by flame spray welding is 6. 3 times that of the matrix. The reason is that the fine crystal grains can be formed and the solution strengthening, dispersion hardening can be induced by these alloy elements. The resistance of the laser remelt coating is 8. 8 times that of the matrix. This is due to the solution strengthening, dispersion hardening and the existence of very hard dendritic crystal, eutectic and martensite in the microstructure.

作者指出，喷涂层由于层内有一定数量高硬度的合金非晶质点存在，其耐磨性是钢基体的4.9倍；喷熔层内合金晶化产生的晶粒细小，合金元素能起固溶强化作用，也能生成化合物产生弥散硬化作用，故此耐磨性是钢基体的6.3倍；激光涂敷层除所含合金元素产生的固溶强化和弥散硬化作用外，表层组织为高硬度的枝晶+共晶和马氏体，故其耐磨性是钢基体的8.8倍。

For the COG joint subjected to thermal storage test at 80 oC for 1000hours, the resistance raises from 0.48 to 1.26Ω while in the sample, the resistance raises from 0.73 to 1.52Ω; all test results fit the reliability requirements. But the reason of increment is not only NCF material degradation cause, but also the bump is elastically. Therefore elastic bump resile caused the resistance to increase after pressing. Consequently I used another two samples which is not thermal aging compared to test samples, the results were show bump resistances increasing about 65%, its come form elastic bumps itself.

COG试片经过80oC约1000小时之后观察电阻上升情形，一片约从0.48Ω上升至1.26Ω另一片从0.73Ω到1.52Ω也符合可靠范围内，但是上升的原因不完全是胶材劣化导致，因为凸块本身具有弹性，所以在压合之后还会回弹造成电阻上升，因此会使用另两片未热时效的试片来比较，得知结果大概65％的电阻上升是来自本身具弹性导致。

Compared with that of 3Cr13 alloy, the oxidation resistance of the composites containing 5 vol.％TiC particle was improved greatly at 850℃, but the improvement was relatively limited at 950℃. But the oxidation resistance of 1Cr18Ni9 composites containing 5 vol.％ TiC particle was obviously improved at 950℃, and at 850℃ the improvement is not large. The TiC particle can improve the oxidation resistance mainly was by developing the oxidation selectiveness of the Cr element as to change the phase constitution of the oxidation film, to alleviate the production of the stress in the oxidation film and to improve the cohesive force of the oxidation film or matrix interface and the chemical combination of the oxidation film.

与3Cr13合金相比，含5％volTiC颗粒的复合材料在850℃的抗氧化性能得到大幅度提高，而在950℃复合材料的抗氧化性能提高作用却是有限的；与1Cr18Ni9合金相比，含5％volTiC颗粒的复合材料在850℃的抗氧化性能略有提高，而950℃复合材料的抗氧化性能提高却是明显的；TiC颗粒可以提高两种基体合金抗氧化性能，主要是通过促进Cr的选择性氧化，进而改变氧化膜的相组成、减缓氧化膜内应力的产生、增加氧化膜/基体界面凝聚力及提高氧化膜化学结合力而实现的。

The 2-D model indicate that integrateddevice structure with bury layer has self-limitation resistance property and specificresistance increase almost linearly with device area.The 3-D model has no property ofself-limitation resistance,while the result is the same as that for specific resistance of2-D structure.

得到的结论是在二维情况下，该结构的电阻具有自限制特性，比电阻具有近似的随尺寸增加而线性增加特性；在三维情况下，其埋层电阻不再具有自限制特性，但比电阻仍然有同样近似线性增加的特性。

In the early stage of diagenesis, the starting resistance is lesser, the fluid in pores is able to flow, the ultra pressure is made up starting resistance and viscous resistance.

因此，启动阻力是泥岩层形成孔隙流体超压的根本原因。

In the middle later period of diagenesis, the starting resistance increases, the fluid is not able to flow, the viscous resistance is equal to zero, the ultra-pressure value is equal to starting resistance.

在成岩作用的早期阶段，泥质岩层启动阻力较小，流体可以流动，流体超压由粘滞阻力和启动阻力两部分组成，当成岩作用进入到中－晚期以后，泥质岩层启动阻力增大，流体不能流动，粘滞阻力近似等于零，超压值等于启动阻力值。

There are four characters that can be found in this process. Firstly, it is a struggle within the political system. In other words, tenants admit the hierarchical rights of ruling class, but reject excess exploit. Secondly, the resistance has various ways, and law is a frequent resort too. Thirdly, collective resistance comes to be the most common form, wealthy peasants always act as organizers and leaders. Fourthly, tenants' resistance processes exhibits obvious different theme of demands in all phrases. Before mid and latter of 14 century, most requirements aim to reject duty beyond custom; while after, mainly to strive for cutting down the rents and tallage.

再次，文章分析了英格兰佃农抗争的四个特点，一是体制内的抗争，即佃农接受统治阶级的等级权利，反抗过度剥削；二是抗争方式多法并举，以法律手段为主；三是集体抗争逐渐成为抗争的主要组织形式，富裕佃农是抗争活动的组织者和领导者；四是抗争历程有着鲜明的时代主题，即以14世纪中后期为界，之前以抵抗领主超出惯例规定的要求为主，之后以争取减免地租捐税为主。

You can do some assertiveness training.
