與單向犁相比,其優點在於:耕地無開、閉壟,地表平整,降低了耕后整地的能量消耗,減少了地頭的空行程,因而大大提高班次生產率。為了滿足犁體梭式作業的要求,我們採用了一隻小容積雙作用的液壓油缸;同時對犁壁曲面的形狀採用了近似圓柱形的對稱設計。但經過一段時間的田間試驗,我們發現:該犁犁胸部分的犁脛和犁鏵上的犁尖在工作中磨損較為嚴重;主犁梁和油缸缸體的連接部分(即油缸底座)突然發生了斷裂,造成整個犁體無法正常工作。The scanning electron microscopic observation on cysticercus cellulosae treated with chinese materia media of compound mienangling and simple prescription in vitro
