产生金属的

In 1791, Volta was the Royal Society Copley Award, and was elected to the Royal Society.

伏打重新做实验，根据相同的金属不能产生电流这个现象，他将注意力转移到了金属本身。1792年，伏打指出，伽伐尼所言的动物电是不存在的。

The lower die shoe often has machined or flame-cut holes that allow slugs and scrap created in the die to fall freely through the die shoe onto the press bed.

本句中的 that allow 引出定语从句，修饰 flame-cut holes ；全句译文：下模座往往具有加工完的或火焰切割后的孔洞，这样可使模具中产生的金属块和金属碎片经过模座自如降落到压床上。

But their resulting inductive reactance is completely swamped the resistance resulting from their being scattered in the metal.

但由此所产生的感抗完全被其在金属中受到散射而产生的电阻掩盖了。

Especially, it seemed to be difficult to achieve such new bone ingrowth on the surface of inert metal material.

但它们仍然存在一些问题：如应力遮挡导致的骨吸收，表面的磨损颗粒，局部的应力不均匀，金属腐蚀而产生的金属离子毒性。

All unique properties of charges, spins and crystal structures of transition metal-oxides can attribute to their symmetrical valence electron orbital. Indeed, many important features, such as high temperature superconductivity, colossal magnetoresistance effect and metal-insulator transition are in closely connection to the complicate charge-spin interaction.

中文摘要过渡金属氧化物中，电荷、自旋及晶体结构等属性，皆与价电子轨域对称性有关，因为它们的电子电荷与自旋彼此间的交互作用，以及晶体结构上的转变，产生如：高温超导、庞磁阻效应及金属绝缘相变等物理特性。

The results of thermodynamics calculation indicated that ScCI3 and ScF3 can be reduced to scandium by magnesium, but Sc2O3 cannot be.

还原产生的初生态Sc与Al形成稳定的Al_3Sc金属间化合物，金属热还原反应的△_rG_m~0减少了-138KJ／mol。

These antennas can cover GSM900/DCS/PCS/UMTS operation. In the chapter 2, the antenna is designed based on the concept of monopole antenna. Furthermore, the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching. In addition, to raise distance between radiation plane and ground will avoid capacitative effect effectually. In the chapter 3, the antenna is designed based on the concept of planar inverted-F antenna. Furthermore, that the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching is similar to chapter 2. But there is a difference in them. We can choose the short position to change input impedance at this structure. In the chapter 4, the antenna is designed based on the concept of planar inverted-F antenna which takes coupled-fed. It will produce the first mode and high-order mode near the frequency, 900MHz. The feature of this type is to reduce the volume effectually. This antenna can not only cover GSM900/DCS/PCS/UMTS operation but maintain good radiation efficiency. Finally, we will compare three antennas, and develop procedure with industrial view, and propose the prospect of the GSM/GPRS antenna in PND, as a conclusion.

在第二章中，我们使用单极天线设计概念，使用双路径架构并於末端耦合来对天线阻抗做匹配，产生涵盖GSM900/DCS/PCS/UMTS四频操作频带，并提高与接地面的辐射高度，以避免电容效应，使天线具有良好的辐射特性；在第三章中，使用倒F形天线设计概念，使用双路径架构於末端耦合，并於辐射臂上采取适当接地点电感效应作输入阻抗匹配，达成涵盖GSM900/DCS/PCS/UMTS系统的四个操作频带；在第四章中，采用倒F形架构并使用耦合馈入方式，使得长辐射金属臂在低频900 MHz附近产生共振，产生低频基频模态及高阶模态，以达成宽频及频宽涵盖GSM900/DCS/PCS/UMTS频带操作，并有效缩减使用体积；最后，分别比较此三种架构的优缺点，再加以业界角度来思考，研发产品天线的流程及思考方向，以及天线应用於可携式导航装置中未来的展望作为本论文的总结。

Stainless steel and other ferrous metals are normally classified as not diamond turnable for the unacceptable tool wear caused by the thermal-chemical reaction between diamond and ferrous metals.

中文摘要不锈钢及其他的铁系金属被归类为不可钻石车削加工，因为在钻石与铁金属之间所产生的热化学反应将造成不可接受的磨耗。

Implementation of the aforementioned circle shear machine would result in major complications in the handling of the metal sheet, since now the metal sheet must be rotated in the middle of the automated line in order to generate a hole cut-out by the circle shear machine.

实施上述圈剪切机，将导致重大并发症，在处理的金属板，因为现在的金属板，必须在旋转中的自动线，以产生一个洞，割出所圈剪切机。

Tension-bending leveler unit is comprehensive and continuous tension leveler roller leveler features, making metal strip stretching in a row, for the turn of the joint role, to have a plastic strip and the extension of access to straightening, the elimination The sheet metal shape defects, such as: the waves, in waves, the channel, such as warping.

拉伸弯曲矫直机组就是综合连续张力矫直机和辊式矫直机的特点，使得金属带材在连续拉伸、连续交替的联合作用下，使带材产生塑性延伸而获得矫直，消除金属板材的板形缺陷，例如：边浪、中浪、槽形、翘曲等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
