文摘:通過對電火花成形機放電狀態的分析，提出了利用分析周期內出現異常放電狀態時間的比例及開路狀態所佔時間的比例，來判別電火花成形加工的間隙放電狀態及其變化趨勢的方法，並在此基礎上利用模糊控制策略實現了對電火花成形加工過程中放電狀態的控制，取得了令人滿意的效果。By having conducted 40ar - 39ar dating of 35 samples and sm - nd dating of 19 samples from the linzizhong volcanic rocks, the post - collision volcanic rocks and a granite dike and the yarlung zangpo ophilite, the dissertation provides significant new data and results for optimizing the time framework of tectonic - magmatic event s of this region. according to isotopic dating of 9 samples, 12 experiments survey in the main trunk profile, the eruption age of the linzizhong volcanic rock in the linzhou basin has been determined as 54 - 64ma
