Objective:Observe the therapeutic effect and lab index changes of metaphase late liver cancer treated by matrine injection together with TACE operation.
目的：观察苦参碱注射液配合TACE术治疗晚期肝癌的疗效及实验室指标的变化。
Factors affect gas lift options: the yield of the well bottom-hole pressure, fluid production index, lifting height and the gas injection pressure.
影响气举方式选择的因素有：井的产率、井底压力、产液指数、举升高度及注气压力等。
So, smaller photoelectric feedback index should be chosen to control the bistability region more effectively, and the period of the time-varying injection current should be small.
因此，为了更有效地控制双稳区，应选取较小的光电反馈率，同时时变注入电流具有较高的扫描速率。
