According to the direct ratio relationship in a certain range between the color degree of the organic solvent with Pb^2＋ and dithizone in the complex compound and the amount of the lead, the amount of the lead can be rapidly determined by way of the visual colorimetry.

再加入双硫腙的三氯甲烷溶液，根据Pb^2＋离子与双硫腙生成的配合物在有机溶剂中的颜色深浅与铅含量在一定范围内成正比的关系，用目视比色法即可快速判断出样品中的铅含量。

After the sample is dissolved and the disturbance eliminated, then dithizone and chloroform solution are added in the sample. According to the direct ratio relationship in a certain range between the color degree of the organic solvent with Pb2+ and dithizone in the complex compound and the amount of the lead, the amount of the lead can be rapidly determined by way of the visual colorimetric.

样品消解并消除干扰离子后，加入双硫腙的三氯甲烷溶液，根据铅与双硫腙生成的络合物在有机溶剂中的颜色深浅与铅含量在一定范围内成正比的关系，用目视比色法即可快速判断出样品中的铅含量。

The compound of active substance after micro encapsulation treatment can be dissolved in organic solvent and its pH value is near to 6. The jointing properties of the flux made by it are perfect and the IMC is thin and transparent.

微胶囊化后的复配活性物质易溶于有机溶剂，pH值接近6以其制备的助焊剂的助焊效果良好，IMC层薄而明晰。

It uses crylic acid resin as filmed material, it also includes following assistant dispersant, sum heat reflecting compound dye, solvent and plastic-strengthening agent.

其采用丙烯酸树脂为成膜材料，其还包括下列辅料分散剂、太阳热反射复合颜料、溶剂和增塑剂。

For example, screen the ink film not only need to have certain hardness to resist abrasion and scratching, innovativeink bhlf and solvents, and so on at the same time there must be sufficient flexibility for the convenience of people on the cards and membership cards to make products in Bend, die-cutting and pressure concavo-convex.

比如说，网印油墨所形成的墨膜不但要具有一定的硬度，以抵抗磨损、划伤、油墨堆积和溶剂侵蚀等问题，同时还要有足够的灵活性，方便人们对制卡和会员卡制作品进行弯曲、模切和压凹凸。

The effect of temperature and concentration and solvent on electrical conductivity of rare-earth nitrates was discussed.

并讨论了它们的电导率随温度和浓度的变化关系以及溶剂对电导率的影响。

Target compounds have been synthesized by condensation of the aromatic nucleus and amino heterocylcle with acyl isocyanates or acylisothiocyanates in absolutely anhydrous and aprotic solvent.

为了寻找高活性的农药品种，利用生物等排原理和亚结构连接法，对脲类化合物的母体结构进行了修饰，将芳氧羧酸类及吡唑环引入酰基脲母体结构中，利用酰基异氰酸酯与杂芳环胺类化合物在无水非质子溶剂中发生亲核加成反应，合成了四个系列21种新的酰基脲类目标化合物。

It was found that the solvent type affected the gel point, the different amount of water addition could alter the structure of condensation polymer, the varying of ageing time influenced the growth of grains and the calcination temperature had great effect on phase structure and grain size.

发现不同的溶剂类型能够改变胶凝时间，加水量的多少会影响醇盐水解缩聚物的结构，陈化时间的长短直接改变晶粒的生长状态，煅烧温度的变化对粉体的相结构和晶粒大小有重要的作用。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
