gravity gradient centrifugation

例句：

1. 1. Gravitational gradient centrifugation is a technique used to separate molecules based on their size and charge.
   重力梯度离心分离法是一种基于分子大小和电荷分离的技术。
2. 2. In this method, the sample is placed in a rotating container and subjected to centrifugal force, which causes the heavier particles to move towards the center of the container.
   在这种方法中，样品被放置在一个旋转的容器中，并受到离心力的作用，这使得较重的颗粒向容器的中心移动。
3. 3. The resulting separation can be analyzed using various techniques, such as size exclusion chromatography or electrophoresis, to identify the different components present in the sample.
   由此得到的分离可以通过各种技术进行分析，如尺寸排阻色谱或电泳，以识别样品中存在的不同成分。
