Experimental results showed that the presence of chloride ion would effectively improve the deposition of metal, and largely increase the square wave anodic stropping peak height of metal depositing.

实验结果显示，分析溶液中含有氯离子可有效地改善金属铋、铅和镉在电极表面的沉积，大幅度地提高沉积金属的方波阳极溶出峰的峰高。

By investigating the performances and chemical stabilities of three anode catalysts, namely, Pt, MoS2 and composite metal sulfide (MoS2/NiS) in the condition of electrochemical oxidation of hydrogen sulfide, it is indicated that MoS2 and MoS2+NiS exhibit better catalytic activity than Pt, and that, at a temperature more than 450℃, MoS2 itself sublimes, while the composite catalyst MoS2/NiS containing both Mo and transition metal Ni remains stable.

考察了3种阳极催化剂Pt、MoS2及复合金属硫化物(MoS2/NiS)电化学氧化硫化氢的性能和在硫化氢环境下的化学稳定性，发现MoS2和复合MoS2/NiS催化剂比Pt具有更好的催化活性，但MoS2在温度超过450℃时会升华，而含有Mo和过渡金属Ni的复合MoS2/NiS催化剂在操作条件下很稳定。

Upon the addition of CdS into the GeS2-Ga2S3 system, the number of the metal-metal bonds and edge-shared GaS4/2 tetrahedra decreases, resulting in the formation of corner-shared tetrahedra with non-bridging sulfurs.

随着CdS逐渐加入到GeS_2-Ga_2S_3玻璃中，金属-金属键和共边连接的GaS_(4／2)四面体逐渐减少，导致相应共角连接四面体和非桥硫的出现和增加。

This was not a good idea, becasue it threw my car up against the fencepost wires that separated my from the drop. There was the howl of metal on metal, the passenger door scraping against taut cables, and a dozen thuds as I bounded off the wood posts, each bang like electricity through a defrillator.

但是这也真的不是什么上策，因为我的车一下子撞到了陡坡的护栏上，虽然阻止我掉下陡坡，却可以听到金属互相摩擦，车门撞击木头栏杆的怦怦声响，每一次都像闪电穿过峡谷般清脆。

As the metal is poured, the foam vaporizes, and the metal takes its place.

当金属浇入时，泡沫材料蒸发，金属取代其位置。

Such as join lubricate in hot candied of the metal, it can lighten the hot candied mechanical intensity, and after the moisture volatilizes, it can form the membrane on the metal surface and improve quality of the product.

如在金属拔丝时加入润滑剂，可减轻拔丝机械强度，并且在水分挥发后，金属丝表面能形成薄膜，可提高制品的质量。

The experiment results shown that: 1 the smaller the pH value, the smaller the use amount of alkaline metal and the alkali earth metal electrolyte demulsifier, when the pH value was 3, the waste fluid could be demulsified no any demulsifier and the use amount of the demulsifier did not increase remarkably along with the wiredrawing fluid concentration increased. 2 Using polymeric ferric sulfate as coagulant demulsifying, when the pH value was 8.4, the best adding amount was 40 mL per liter wastewater and the best precipitation time was 4 hours. Then the COD concentration was 480 mg/L, reaching the water quality requirements to enter the sewage treatment plant.

pH值越小，碱金属和碱土金属电解质破乳剂的用量越小，pH值为3时，无须加入任何破乳剂即可破乳；破乳剂用量并不随拉丝液浓度的增大而显著增加。2）用混凝剂聚合硫酸铁破乳，在pH值8.4时，最佳投加量为40 mL/L，最佳沉淀时间4 h，处理后上清液COD浓度为480 mg/L，能满足进入污水处理厂水质要求。

Metal detectors cannot be used in many cases because landmines can be made of non-metal materials.

金属探测器无法使用，因为在许多情况下，地雷可以是非金属材料制成。

But it was the thousands of metal fragments that did the real damage, ripping and screaming through the air, to bounce off stone or metal, or all too often to cut through flesh.

但是数千金属破片足以造成实实在在的破坏，带着尖厉的啸叫撕裂了空气，在石头和金属上迸射弹跳，或是有太多的机会刺穿身躯。

I can still vividly recall the impressive scenes you gave. You were among my friends and relatives who accompanied me from my house to the seaport and when the porters were slow to show up, you obligingly carried my suitcase for me.

你对我的种种感人情意，使我记忆犹新，那天你随着我的亲友从家里送我上轮船，搬运工迟迟不来，你毅然替我提着皮箱上船。

St. Nicholas became the patron saint of Russia, where he was famous for his red cape, flowing white beard, and bishop's mitre.
