查询词典 preference bond

The purpose of this study was to evaluate the shear bond strength between porcelain and electroformed copings after different surface treatments, with comparison of Ni-Cr alloys, to explore the bonding mechanism through observing the electroformed coping surface and interface of metal-ceramic by SEM and EDS analysis. It will provide the basis for clinical application. PartⅠEffects of different surface treatments on bond strength of porcelain fused to eleetroformed copings Materials and Methods: Forty-five cylindrical Ni-Cr alloys were made, and gold copings were deposited on them and divided into 5 groups randomly.

本实验拟测量金沉积基底几种不同表面处理后的金瓷剪切强度，并与Ni-Cr合金进行比较；通过对不同表面处理后的金沉积基底、金瓷界面进行扫描电镜观察和能谱分析，探讨不同表面处理对金沉积金瓷结合的影响，为金沉积烤瓷修复体的临床应用提供参考依据。

Fracture model and shear bond strength were not relevant. Conclusions: The shear bond strength between porcelain and electroformed copings are significantly lower than that of Ni-Cr alloy.

结果：金沉积5个处理组的金瓷剪切强度分别为6.99MPa、9.04 SPa、9.80 SPa、12.19 SPa、12.86 SPa，低于Ni-Cr合金26.76 MPa(P＜0.05)；断裂模式与剪切强度之间没有相关性。

According to the empirical rules of influence of the chemical bond on spectrum, electron spectroscopy and Mossbauer spectroscopy, the chemical environmental factor was further defined with the covalency and polarizability of a bond.

根据光谱、电子能谱和穆斯堡尔谱学中化学键对谱线影响的经验规律，进一步利用共价性和极化率定义了化学环境因子这一概念，并发现它能够有效地描述波谱学中化学位移的变化趋势。

The lower energy is because that the chemical bond between O〓 and M〓 has not formed completely, which cause by the higher covalency of Eu〓-O〓 bond in amorphous state. And the larger half width is caused by the disorder of sites.

这是由于在非晶态状态下金属氧键尚未完全形成，从而导致Eu〓-O〓的共价性较高，因此电荷迁移带处于较低的能量位置；而格位的无序性导致其光谱变宽。

Fir Fortunately Seiki leading products: 1, bulging packages (also known as the swelling sets, key-free bearings, bushings-free bond, the bond-free coupling, internal and external expansion sets) 2, coupling mainly patch-coupling, precision servo motor couplings, air compressor for flexible coupling, no backlash precision flexible coupling, the universal joint, the plum blossom - Shaft, etc.

杉幸精机主导产品：1、胀套(又称胀紧套，免键轴承，免键衬套，免键式联轴器，内外膨胀套)；2、联轴器(主要有膜片联轴器，精密伺服电机联轴器，空压机专用高弹性联轴器，无背隙精密弹性联轴器，万向联轴器，梅花型联轴器等)；3、扭力限制器(按照国际标准，可完全替代日本，台湾，欧美进口产品)。

Forty-year bonds; instead we tried to concentrate in the straight bond area onundervalued because of bond market inefficiencies.

的债券，顶多是那些较短期且备有偿债基金或是因市场缺乏效率而使得价格被低估的

The force is dominated by entropy force when the chain isdeformed less than 0.9 of the full-extended chain, while by enthalpy force. Theenthalpy force is contributed by the intro-molecular interaction. Bond stretchcontributes to the force more than bond angle bend. Torsion and VDW contributelittle to the force.3. The internal energy contribution to the elastic force It is in dispute that whether 〓 is dependent on the strain, and it is hard toresolve the problem using present elastic theories because they are athermal.

我们模拟了聚乙烯模型聚合物的SMFS，研究了链长、势能有效距离和温度对力谱的影响，探讨了力谱的本质问题，得到以下结果：改进的分子动力学方法可以很好的模拟聚合物的SMFS；SMFS是链段的性质而不是整个高分子链的性质，对于聚乙烯，该链段碳原子数目大于40；SMFS的本质是熵弹性，形变小于全伸直链的0.9时，力为熵弹力；形变超过全伸直链的0.9时，能弹力占主导地位，这种能弹力完全是分子内相互作用引起的，是由键伸缩和键角弯曲贡献的。3。
