The rate of sedimentation depends on the molecular weight of the molecule and thus the ultracentrifuge and be used to separate a mixture of large molecules, such as large colloidal proteins, and estimate particle sizes.

物质沉淀率取决于分子本身的重量，所以可用超速离心机分离大分子混合物，如：大胶体蛋白，或用于检测物质颗粒大小。

Ultracentrifuge A high-speed centrifuge, operating at up to a million revolutions per second that is used to sediment protein and nucleic acid molecules.

超速离心机：一种高速离心设备，运转时转速可达每秒百万转，常用于沉淀分离蛋白质与核酸分子。

A major goal in this field is to identify drug-induced molecular changes and their effects on brain function. By the advance of high throughput technologies in genomics and transcriptomics, the whole gene expression profile in addicted brain could be obtained and proved to be a very powerful tool to unclose the molecular mechanism underlying the addiction biology context.

毒品成瘾研究的一个主要目标是鉴别和分离毒品导致脑功能障碍的分子机制；采用高通量的基因表达谱技术研究毒品成瘾者在不同状态下脑基因表达全貌，对深入认识毒品成瘾的机制具有重要的意义。

But when there are mutations in either molecule, they become uncoupled.

但是，当两个分子中任一发生突变，他们的作用就会分离。

We want to go on and measure the rate of molecular evolution for humans, as well as doing more work with moa and Antarctic fish to see if rates of DNA change are uncoupled in these species.

我们想要进一步检测人类的分子进化速率，对于恐鸟和南极鱼类也有做更多研究的打算，想看看这些物种的DNA和形态的进化速率是否分离。

The separation of multi-component stable isotopes in aceatrifuge cascade has been shown to be a set of functions of an overall separation factor per unit relative molecular mass difference.

通过对不同形式的离心级联进行丰度计算，得到任意两种组分间的全分离因子与它们的相对分子质量之差成指数关系。

It can grow all right in high salt Since twenty century , molecular biology and bio-technology have a large development , agriculture and physic have been speedily development too ,especially after the plan of human genome was successfully implemented ,more people engaged in bio-technology industry .but the area of the bio-technology study was very extensive , Ocean Rhodotorulas have been studied by people at beginning, on the end of 1980s , Ocean Rhodotorulas separation from sea and Japan was the first succeed in cultivation by zymolysis , the Ocean Rhodotorula of cultivation was used for a good nutrimental to feed for fish and shrimp.

二十世纪以来，分子生物学与生物技术得到了迅猛发展，在农业和医药业都得到了飞速发展，尤其是人类基因组计划的成功实施，使人们更多的从事着生物技术行业，但是生物技术研究的范围很广，所以对于海洋红酵母的研究还处于刚刚起步阶段，上世纪80年代日本最早分离到海洋红酵母，然后发酵培养，用做鱼虾的营养饲料。
