A large number of studies have demonstrated that imposex in marine gastropods is induced mostly by organotin pollutants. But the mechanism of imposex has not been identified.

大量事实证明，有机锡污染是导致海洋腹足类动物发生性畸变的主要原因，但有机锡致性畸变的机制尚未完全清楚。

It improves the machinability of steels because of brittlement of grain boundaries resulting from the tin segregating on the grain boundaries of the steels.

锡可有效改善钢材的易切削性能，原因是在切削温度范围内富集在晶界的锡使钢材的塑性降低。

This paper introduces not only deposition of tin oxide thin film, but also doping silica oxide in the film to control the grain size of tin oxide, and improve the sensitivity of the sensor.

论文中除了沈积二氧化锡薄膜外，亦於薄膜内掺杂二氧化矽，藉此以抑制二氧化锡晶粒成长、提升其灵敏度。

Business scope: Electronic tools, welding tools, soldering iron gun glue, hardware tools, electrical tools, Static, tin tin lines and dressing article.

经营范围：电子工具、焊接工具、烙铁胶枪、五金工具、电工工具、防静电产品、锡条锡线及敷料。

Absorb gun has strong power for speedy desoldering and cleaning at the same time.

吸锡枪吸力强，除锡快而干净，节省时间。

The promotion of coal liquefaction by iron and tin has been compared in two Victorian brown coals, Morwell and Coolungoolun. Tin was more effective in the low-sulphur Mouwell coal, whereas iron was better suited to the high-sulphur Coolungoolun coal.

我们以Morwell和Coolungoolun两种维多利亚褐煤进行实验，对铁和锡在煤的液化中的催化作用进行了比较，发现锡对低硫的Morwell煤较为有效，而铁则更适合于高硫的Coolungoolun煤。

This kind of sulfide ore is relatively refractory and it is difficult to improve production ibexes, with high cost and low benefit.

矿石选矿工艺矿物学研究结果表明：(1)泡金山锡石硫化矿锡石结晶粒度细，属甚微嵌布，为甚难选矿石。

The recovery of tin and nitric acid from the spent solder stripper, and the feasibility of recovering nitric acid were investigated by determining diffusion dialysis coefficient of the dialysis membrane for different spent liquor including iron,copper and tin.

通过考察铁盐、铜盐和亚锡盐对硝酸扩散系数的影响研究了采用扩散渗析法从废退锡液中回收硝酸的可行性，实际样品的研究表明，扩散渗析法回收硝酸的回收率在70％以上。

It must be grinded strictly before processing;(2) sulphide iron ore has high tin content, it is necessary to recover tin ore from this mineral.

选别时必须磨到一定的细度；(2)硫铁矿物含锡高，有必要在硫铁矿物中回收锡石。

The results showed 3 types of aluminum compound prepared in this paper all had good poison protection effectiveness on such impurities as stannous chloride,lead oxide,sodium hydrogen sulfate,and so on.Moreover,the mechanism of the poison of catalyst was also discussed.

结果表明，合成的3种防中毒剂即防－1、防－2(主要成分为乙酰丙酮合铝)及防－3(主要成分为二乙酰丙酮基异丙氧基铝)对二月桂酸二丁基锡、氯化亚锡、二正丁胺、硫脲、氧化铅及硫酸氢钠等杂质均有较好的防中毒作用；不同防中毒剂对不同杂质的防中毒作用有一定的选择性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
