The purpose of the study is to investingate the feasibility of closed-microwave method instead of traditional aqua regia hotplate reflux method for heavy metal determination in soil.

中文摘要本研究利用密闭微波法消化土壤，并以火焰式原子吸收光谱法分析镉、铜、铅、锌四种金属元素，目的在探讨以密闭微波法取代传统王水热板回流消化法，测定土中重金属之可行性。

Mineralization consists of galena, sphalerite, pyrite, and minor chalcopyrite, tetrahedrite and argentite in a gangue of mainly quartz and clay minerals.

矿化包含方铅矿、闪锌矿、黄铁矿、次生黄铜矿、及主要物质为石英和粘土矿物脉石内的黝铜矿和辉银矿。

Exposed argentite could be dissolved in thiourea acidified by sulphuric acid ,since native Ag is not dissolved in non-oxidizing inorganic acids , hydrochloric acid was used to dissolve the sphalerite and to soak out the argentite which was enveloped in sphalerite .

继以硫酸酸化的硫脲溶剂溶解裸露的辉银矿，然后根据自然银在非氧化性的无机酸中不溶的特性，采用盐酸溶解闪锌矿并浸

The dispersed states of ZnO, CaCO3, argil, clay, carbon black and carbon white in SBR matrix were characterized by electronic microscope TEM and SEM. To make a comparison with the above, the dispersed states of clay/rubber nanocomposites were studied and compared with that of clay/PMMA nanocomposite. According to TEM and SEM photos, there are several levels of dispersed structure with different dimension.

将透射电子显微镜与扫描电子显微镜结合在一起，系统观察了氧化锌、碳酸钙、陶土、粘土、炭黑、白炭黑等填料在丁苯橡胶中的分散状态，也考察了粘土/橡胶纳米复合材料中粘土晶层的分散情况。

Some elements were more common than others, but everything from argon to zinc was there.

一些元素要比其他元素更普遍，但是所有的元素都在氩和锌之间。

At present, the most commonly used are zinc oxide arrester.

目前，使用最多的是氧化锌避雷器。

The main methods for measurement of the resistance leakage currents of metal oxide arrester were introduced in this paper.

本文介绍了目前常用的监测氧化锌避雷器泄露电流的方法，即：全电流法，补偿法，基次谐波法和三次谐波法，并分析了每种方法的优缺点。

It is necessary for on-line monitoring system for Metal Oxide Arrester to detect its problem and ensure the safe operation of the power system.

氧化锌避雷器在线监测系统对及时发现其存在的问题，保证电力系统安全工作，是非常必要的。

Mounting height is one of important factors effecting the potential distribution of porcelain ZnO arrester.

中文摘要：安装高度对瓷套式氧化锌避雷器的电位分布有重要的影响。

To actualize condition-based maintenance for Metal-Oxide Arrestor, which is a kind of important device used to restrain overvoltage in the electric power system, the research of on-line monitoring of MOA is important and necessary.

金属氧化锌避雷器MOA作为电力系统重要的过电压保护设备，对其开展在线监测是实现状态维修的必然要求。

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。
