查询词典 precipitated

As the brazing temperature was low or the holding time was short, lots of low-melting M3B2 were precipitated in the central part of the brazing seam.

当钎焊温度较低或保温时间较短时，钎缝中央生成大量的M3B2；随着钎焊温度的升高及保温时间的延长，钎缝中M3B2、MC减少，M23C6增多、长大。

Sometimes latent mental disorders are precipitated by stressful circumstances, as in the case of manic-depressive psychosis, schizophrenia, hysteria and neurasthenia.

Experimental results showed that the CPF improved the retention of precipitated calcium carbonate filler significantly. With 0.9% CPF (based on oven-dry pulp), the retention of PCC increased from 57.53% to 72.21%. The physical properties of paper were also slightly improved. The tensile strength and burst strength of the paper with CPF were higher than those with CPAM.

结果表明，用作麦草浆湿部添加剂的制得的阳离子纸浆纤维能显著提高沉淀碳酸钙填料的留着率，添加0.9%的CPF即可使PCC的留着率从57.53%提高到72.21%，同时能够对纸张的物理性能有所改善，添加CPF的麦草浆成纸的抗张强度和耐破强度要明显高于添加CPAM的，而不低于添加未改性加拿大漂白针叶木浆纤维的。

The resultant cationized pulp fibers can obviously improve the retention of precipitated calcium carbonate filler in the furnish. Adding 2% of CPF （based on oven-dry pulp） can improve the retention of PCC from 61.1% to 83.4%, compared with the retention of PCC only 78.2% by adding 0.05% of CPAM, and also the application of CPF is better than adding EPI-DMA directly. At the same time, CPF can improve the drainage performance of the stock.

制得的CPF能显著提高沉淀碳酸钙填料的留着率，用量为2%的CPF即可使PCC的留着率从61.1%提高到83.4%，而CPAM在最佳添加量0.05%时仅使其留着率提高到78.2%，CPF应用性能优于直接添加EPI-DMA，同时CPF能够改善浆料的滤水性能。

In the microstructure of solder matrix, Ce-dope results in the formation of precipitated CeSn3 clusters in the reflowed solder matrix and the oxidation of CeSn3 clusters makes the tin whisker grow.

在添加稀土元素后，锡球内部可观察到CeSn3介金属，CeSn3氧化后可观察到锡须形成，导致此种无铅焊锡在使用上将因可靠度而受到限制。

CTAB was used to pyrolyse plant cell and reacted with the released cell nucleic acid to form nucleic acid-CTAB complex, the cell extract was then deproteined with chloroform-isoamylol, at last RNA was selectively precipitated by LiCl.

采用CTAB裂解植物材料，与细胞中的核酸形成核酸-CTAB复合体，然后用氯仿一异戊醇去除细胞裂解液中的蛋白，最后采用LiCl选择性沉淀其中的RNA。

CTAB was used to pyrolyse plant cell and reacted with the released cell nucleic acid to form nucleic acid-CTAB complex,the cell extract was then deproteined with chloroform-isoamylol,at last RNA was selectively precipitated by LiCl.

但是一般高等植物组织内都含有多糖类物质，这些物质的存在严重影响RNA的提取，如果去除不净，将影响反转录、扩增等下游操作。

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％。
