查询词典 zinc-plating

One company provides customized zinc fingers, but Voytas, J. Keith Joung of Massachusetts General Hospital in Boston, and their colleagues have instead developed a zinc-finger resource freely available to other researchers for generating the appropriate nucleases.

一家公司提供商业化的锌指结构，但是丹尼尔和波士顿马萨诸塞州总医院的J·基思将锌指资源免费提供给其他想得到特定核酸酶的研究人员。

Zinc-coated steel and other zinc containing products are slow to enter the recycling circuit due to the very nature of their durability.

镀锌钢材和其它含锌产品因为耐用性比较长，所以进入回收循环很慢。

A series of spot welding technology and joint tensile-shear tests for uncoated low carbon, electroplated and two kinds of hot dipped zinc-coated steels were made to improve the quality of spot welding joint for zinc-coated steels. The test results were analyzed with computer regressive method. The effects of welding current or time on nugget diameter or joint tensile-shear strength and critical curves in splash generation for spot welding were obtained.

摘 要：为提高镀锌钢板点焊接头的质量，对普通冷轧钢板、电镀锌钢板和两种镀锌层厚度不同的热镀锌钢板进行了一组点焊工艺及接点强度试验，并对试验结果进行了计算机回归分析，分别得出了这几种材料在不同的焊接电流、焊接时间下的点焊熔核直径或接头拉剪强度变化曲线以及点焊飞溅临界曲线。

The concentrate is brought to a temperature of more than 900°C where zinc sulphide converts into the more active zinc oxide.

当锌精矿加热到超过900℃时，硫化锌转变成更活泼的氧化锌。

The zinc oxidation leaching ratio can reach 86.73% in 96h. The oxidation mechanisms of zinc sulphide concentrate in different suspension electrolysis solution are almost same. However, the exchange current density in the process of oxidation is low and it will quicken electrochemical oxidation with the increasement of temperature.

通过实验分析得出：硫化锌矿在不同悬浮电解溶液中都能够被氧化，但有较大的差别，在硫酸锌、硫酸铵和硫酸的悬浮电解液中，矿物明显被氧化而溶解进入悬浮液中，氧化速度比较快，锌的氧化溶出率在96h的时间内达到86.73％。
