This review focused on extraction mode, preparation of stationary phases, optimization of parameters and its on-line coupling with chromatograph.
本文主要综述了毛细管内固相微萃取技术的萃取模式、固定相制备、萃取参数优化及与色谱在线联用情况。

At startup, there is no back-EMF due to the stationary motor, and the motor position cannot be detected in sensorless mode.
在启动时，没有反电动势，在无传感器模式下电机的位置不能检测到。

First we employ EMD method to decompose the crude oil prices in NYMEX, and obtain a series of intrinsic mode function (IMF), which are stationary and of strong periodicity, and a trend term.
