The metal nanocrystals memories come into notice as so many advantages. The advantages of metal nanocrystals over their semiconductor counterparts include low power consumption, higher density of states, smaller energy perturbation due to carrier confinement, stronger coupling with the channel, better size scalability, and the design freedom of engineering the work functions to optimize device characteristics.

然而金属的量子点记忆体在近年来受到瞩目，其相对於传统半导体材料用於量子点记忆体上，有诸多的优势，其优势包含低功率耗损、高密度的能阶、没有明显的量子局限效应、有效降低元件尺度、且可调变的空间大，因为随不同的金属有不同的功函数。

The acidic composition can be prepared by mixing a monovalent or polyvalent cation and an organic acid in the presence of a strong oxyacid, wherein the resultant acidic composition is less corrosive to a ferrous metal than a solution of a mineral acid having the same acidic pH value as that of the acidic composition, and where in the acid composition is more biocidal than a mixture of the organic acid and a metal salt of the organic acid which mixture has the same acid normality value as that of the acidic composition.

The experimental results indicated that the longer the po uring intervallic time of the two kinds of molten metal and the higher the heigh t of the molten iron to pour into the tip of dipper teeth , the narrower its tran sitional zone will be, on the contrary, the wider its transitional zone will be.

用不同粘度的流体通过水力模拟的方法近似地描述了双金属斗齿过渡区的混合状态。试验结果表明：两种液体浇注的间隔时间越长，先浇入的铁液液面越高，过渡区越窄；反之，过渡区越宽。生产中为了保证过渡区双金属的结合质量，应控制较高的铁液液面高度及一定的双液间隔时间

Several novel structures have been determined: Unique ninenuclear complexesincorporating 3d, 4f metals with a sodium ion center, the sodium ion may be serve as atemplate in the formation of these novel complexes; Novel tetranuclear 〓complexes with channels formed by intermolecular weak interactions; First 〓type tetranuclear complex; Peculiar "dimer of dimers" complexes derived frombinuclear complex; Unusual one-dimensional wave chain formed by weakcoordination bonds and hydrogen bonds and two dimensional coordination polymerconstructed through coordination bonds and hydrogen bonds.

Written in the "Victoriandustrial", harpsichord-laden Gothic style of "Opheliac" but with a metal edge,"Laced / Unlaced" shows the evolution from child prodigy classical violinist to reigning queen of metal Gothic / Industrial violin, and beckons us ever deeper into EMILIE AUTUMN's strange world with a flick of her black-nail-polished fingers.

写于&Victoriandustrial&，其中满载着大键琴哥特风格的&Opheliac&更添一丝阴暗金属的风味。&Laced / Unlaced&向我们展示的是她从一个天才少年古典提琴手向一个哥特金属/工业提琴女王的蜕变，同时跟随着她那涂着黑色指甲油的手指在琴弦上的游动，我们也被深深吸引到EMILIE AUTUMN那神奇的世界中去。

Experience shows that the introduced magnetic field can give an effective intervention to the transition of droplet, flowing of molten bath metal, crystalline and nucleation of molten bath and the process of crystalline growth. The magnetic field promotes the refining degree of primary crystallization structure , decreases the chemistry non-homogeneity, So it can strengthen hardness and wearing resistance of weld metal overlay and improve quality of surfacing deposit.

实践表明，利用外加磁场对焊接中熔滴的过渡、熔池金属的流动、熔池的结晶形核及结晶生长等过程有显著作用，使堆焊层的一次结晶组织细化，控制硬质相的分布，减小化学不均匀性，从而提高了堆焊层金属的硬度和耐磨性，全面改善堆焊层的性能。

This, it would be necessary only to make a little ball of earth that can be accurately weighed ; then we could easily calculate how many times the earth is larger than this little ball; and by so doing, we might tell, at one's fingerends, that — if we suppose the little earth-ball to weigh a hundred-weight — the whole globe, being so many times larger, must weigh so many hundred- weights.

可是，这样的做法极可能误导我们。因为一切取决于制造小球的物质。如果用酥松的泥土制造小球，它的重量就小；如果泥土中掺杂石头，它的重量就大一些；如果掺杂金属，取决于掺杂金属的种类，它的重量将更大。

All the actuators of the three-axis turntable are brushless torque motors, all the bearings are aerostatic air bearings, so the friction caused by these elements can be neglected. The main source of friction is the metal-to-metal friction on the slip rings. Hence the "Columb+Viscous+Static" friction model is used here for analysis.

由于三轴转台的驱动系统选用的是无刷电机，轴承则采用的是气浮轴承，轴系上的摩擦力已大大降低，三轴转台上的摩擦主要是滑环轴上金属对金属的摩擦，所以文中选用&库仑＋粘滞＋静摩擦&的摩擦模型来进行分析。

Remembering the period of Taiwan good economy starting from 1960 to 1980, some large-scale iron factories like the East Asia and the Ming Changxing made products of general steel, aluminum alloy and stainless steel and shown up in every large construction projects. Some factories with the best techniques like the Jusin Metal were capable for making large outdoors landscape sculptures of stainless steel for the artistic Master Mr. YuYu Yang. Some factories like the Tungchang Metal kept in small but profitable operation.

记得在台湾经济起飞的50年代至70年代，这些铁工厂从一般的钢件的制作，到铝合金及不锈钢产品的制作，当时大型如东亚不锈钢及明昌兴铝门窗综横在各个营造工地，也有技术精湛如久信金属承接杨英风设计大师不锈钢展示品的制作，或是像东錩金属的小而美经营，而这样的传统铁工厂如今仍遍布在台湾的大街小巷，他们如何能再创造出另一番光景，他们的下一代应何去何从？

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。
