斜率

It can be concluded that to meet with the ideal separation effect in a relative short period, the following optional selection of experimental conditions should be carried on strictly: centrifuge rotor and gradient medium, which will influence separation capability; gradient density range, shape and slope, which is very important in separation degree; the methods of reorienting rotor,low and high rotor speed exchange and Gmax could be used in order to shorten separating time.

通过研究认为在相对短的时间内要达到理想的分离效果，应该对以下实验条件进行优化选择并严格控制：包括实验中影响分离本领的转头、梯度介质选择；为获得满意分离度应严格选择梯度的密度范围、梯度形状以及梯度的斜率；为了缩短分离时间，可采用重定向梯度、二次变速及Gmax等方法。
