The metallogenic material was from deep alkalic basaltic magma, and the pulsatory invasion was the necessary metallogenic condition of the ore deposit. 成矿物质源于碱性玄武岩浆，基性次火山岩浆多次脉动式入侵是矿床形成的必要条件。
Pulsatory blood flow signals within the tumor were observed in HCC 82(91.1%)and “basket”pattern was found in 65(72.2%). 原发性肝癌组中82个病灶可见搏动性血流信号(91.;1%25)，其中65个为“篮网”状(72
