By analyzing and comparing the above test results, the special demands for welding current and time and pressure in the spot welding of zinc-coated steels were put forward.

根据对上述试验结果的分析和比较，提出了锌镀钢板点焊时焊接电流、焊接时间和电极压力等参数的选用原则，并对几种镀锌钢板给出了相应的点焊规范范围。

By analyzing and comparing the above test results, the special demands for welding current and time and pressure in the spot welding of zinc-coated steels were put forward.

而在这些产品的装配和制造中，往往会用到电阻点焊方法，由于镀锌钢板表面锌层的熔点很低、硬度也低，给点焊带来一定的困难［1］。

By analyzing and comparing the above test results, the special demands for welding current and time and pressure in the spot welding of zinc-coated steels were put forward. The relevant spot welding parameters for every kind of zinc-coated steels were proposed.

根据对上述试验结果的分析和比较，提出了锌镀钢板点焊时焊接电流、焊接时间和电极压力等参数的选用原则，并对几种镀锌钢板给出了相应的点焊规范范围。

The beauty of zinc-finger nucleases lies in their simplicity. Where other methods are long, arduous and often messy, it is relatively easy to switch off genes using this method.

锌指核酸酶的美妙之处就在于其简单性，比起其它费时、费力又麻烦的方法来，利用锌指核酸酶的方法能够相对容易地沉默基因。

About 6 years ago, Dana Carroll of the University of Utah in Salt Lake City and colleagues built zinc fingers--molecules that recognize and attach to specific DNA sequences--and joined them with enzymes that slice through the DNA at that same spot to create zinc-finger nucleases.

大约6年前，盐湖城犹他大学的达娜·卡罗尔和同事建立锌指分子结构，它可以识别及固定在特定的DNA序列上，然后与可以在同一点切割DNA的酶结合，形成锌指核酸酶。

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。

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。
