Recently, in order to adapt to the demands of environmental protection, for surface finishing of varnish is progressively from solvent-based light oil to water-based conversion varnish.

近来，为了适应环保要求，用于表面加工的光油正逐步从溶剂型光油向水性光油转化。

And machiningresidual Roller blade on optical device generally limited to UV glazing, polishing of water-borne light oil and solvent-based varnish glazing is vulnerable to the paper, which has been embroiled in roller is very limited.

而辊筒上光机加风刀装置一般限于UV上光，水性光油上光和溶剂型光油上光也容易造成纸张卷入辊筒，其作用非常有限。

Surfactant sorbed on soil increases the adsorption capacity of the soil; however, the microemulsion composed of surfactant and organic materials decreases the adsorption capacity of the soil.

增加离子强度对非离子表面活性剂的吸附无影响，却可略微增加阴离子表面活性剂的吸附。表面活性剂吸附于土壤后对憎水性污染物在土壤/水间的分配行为产生显著作用。

In order to research and evaluate the safety of food packaging of plasticizer Di-2-ethylhexyl phthalatein PVC film, the migration rate of DEHP from PVC film into water food simulants (distilled water, 65% aqueous ethanol, 20% aqueous ethanol, 4% aqueous acetic acid) was studied at 17, 30, 40, 50 and 60℃ by Gas Chromatography.

为了研究评判PVC膜中增塑剂邻苯二甲酸二异辛酯在食品包装中的安全性，采用气相色谱仪测试了几种水性溶剂（蒸馏水、65%乙醇、20%乙醇、4%乙酸）在不同温度（17℃、30℃、40℃、50℃、60℃）下对PVC膜中增塑剂DEHP的溶出率。

The results show that DEHP can migrate into all water food simulants from PVC film and the migration rate was the highest in 65% aqueous ethanol with the range 0.85%～6.31% and a big increasing amplitude when contacting temperature over 30℃, the rate was lower in 20% aqueous ethanol and distilled water with the range 0.19%～0.45% and 0.19%～0.37%, respectively; and the rate was the lowest in 4% aqueous acetic acid with the picked out rate 17% and the value ＜0.4%.

研究结果表明，PVC膜中DEHP在几种水性溶剂中均有溶出，在65%乙醇中溶出率最大，范围为0.85%～6.31%，当浸泡温度超出30℃后，溶出率增幅较大；在20%乙醇和蒸馏水中的溶出率较小，范围为0.19%～0.45%和0.19%～0.37%；4%乙酸对DEHP的溶出作用最小，70个样品中，检出率为17%，检出溶出率。4%。

Efficient on-line clean-up and concentration atrazine and simazine was studied by the pre-column as the first column and an ODS column (250mm×4.6mm I.D) as the second column.

该系统能对具有一定疏水性的化合物进行在线富集，实现环境及生物复杂样品直接进样分离分析。

The result showed that after the treatment of the high-shear fiber kneader, the content of shives of the pulp will decrease 87％or more, the tensile index of the pulp sheets increases 22.6％, the tear index increases 28.8％, and the burst index increases 39.1％.

实验结果表明：纸浆中的纤维束去除率可达87％以上；纸浆纤维形态发生了变化，纤维的柔软度有所提高；纸浆的游离度略有下降，但对纸浆滤水性能影响甚微。

General Paint external walls of scrims standard closed Primer is set high alkali, high adhesion, water resistance and anti-salting-out that combines the functions of the external walls of water-borne closed primer.

漆将军标准型外墙抗碱封闭底漆是集高度抗碱、高附着力、防盐析及耐水功能为一体的外墙水性封闭底漆。

The method worked quite well, there was not much damage on the plastic, and the acrylic paint and lacquer primer are all gone.

这方法不错，珐琅油层被煞车油浸得剥落了，水性油层则被煞车油溶解了；而塑胶的质地只轻微变弱，没有出现严重爆胶的情况。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
