摘　　要：将甘蓝型油菜自交系材料8307C的白花基因和不育株101-007AB的隐性核不育基因分别导入自交系自2512C,采用杂交、自交、连续回交、自交育性分离、株系内兄妹交转育成新的高含油量、高蛋白、高配合力的双低油菜＂白花＋隐性核不育＂两型系2512AB。＂白花＋隐性核不育＂两型系2512AB具有高含油量（44.81%）、高蛋白（28.20%）、高配合力（一般配合力）、低芥酸（0.02%）、低硫苷（19.72μmol/g）等优良性状,恢复源广,较易配制出强优势的杂交组合,具有较好的开发应用前景。The function and basic principle of underground diaphragm wall hydraulic grab control system were analyzed. Based on the theory of power bond graph, the bond graph model of the system was established. Independent variable＇ s integrations of capacitive element and inertial element were selected as state variables, and the state equations were deduced. Simulation results based on MATLAB prove the control system has very excellent characteristics. Finally, the influence of the changed parameters on the system was also discussed.
