过滤

Mixed cellulose ester membranefor hydrophilic is a mixture of cellulose acetatecellulose nitrate.

混合纤维素酯膜由硝酸纤维素酯和醋酸纤维素酯制成，是一种多孔性的精密过滤材料，滤膜表面孔径分布均。

D. During the course of our study, we found that both PNIP and PNIP-enzyme labelled antibody could adhere quickly and tightly to the cellulose acetate and nitrate membrane either below or above the LCST.

在高于LCST的温度下过滤，其保留率较高；而抗原、抗体及酶标抗体等蛋白质对膜的吸附作用很弱，可以通过洗涤滤过纤维素膜。

They are heavily censored by your commi govt and you can't get any valuable news from there.

那些网站被你们的共党政府过滤过了你从那边得不到任何有价值的新闻。

Crude EO was then dissolved with ethanol, frozen at - 15 ℃ for 48 h, and centrifugally separated and filtered to get rid of impurities. The final product EO with yield of 2.09 ％ and purity of 99.0 ％ was then obtained after distilling the liquor under vacuum.

往精油粗产品中加入乙醇溶解，放入-15℃冰箱中冷冻48 h，离心分离去除树脂状物质，过滤，滤液进行真空浓缩后，即得精油，产率约2.09％，精油纯度99.0％。

As for purification, there was no significant difference between filter and centrifugation methods.

对比离心纯化与过滤纯化，并未发现两者之间的差异。

Mechanisms to concentrate proteins are well known in the art and typically involve filters or centrifugation.

浓缩蛋白的机理是本领域中公知的，且一般包括过滤或离心。

When the beers are not easily filtered, they sometimes can be separated by centrifugation, which is the subject of this chapter.

当发酵液不易被过滤纯化时，我们可以采用离心的方法来分离，这也是这章的主题。

Clarification can be carried out by filtration, centrifugation, or more commonly by setting and decantation.

澄清的完成通过过滤、离心、更普通的是沉淀和转移。

However, many biological feeds, which can be centrifuged can not be effectively filtered, so that centrifugation is often an attractive alternative.

但是，对大多数生物发酵液可以离心但不能有效地过滤分离，所以离心往往是很有效的方法。

The paper describes the status of screen bowl centrifuge used both at home and abroad and gives an analysis on its application in China.

介绍了国内外沉降过滤式离心机的状况，分析了在我国的使用情况，并提出了加快发展的建议。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
