This paper draws conclusions from the studies on five typical deposits which are distributed in the west of lanping - simao basin. these conclusions are as follows : the types of copper deposits are different because the geological backgrounds of this area in different period are different ; songjiapo copper deposit belongs to a typical porphyry deposit, its mineral liquid mainly come from the magma that formed the triassic eruptive rocks and effected by the subsequent geological action ; jinman copper deposit, shuixie copper deposit and kedengjian copper deposit are the hydrothermal type
文章在綜合分析、比較各礦床的礦床地質和地球化學特徵的基礎上，還結合了研究區的地質背景資料，研究了前人的成果和認識，初步分析了區域不同類型銅礦床的形成機制，探索性地提出了各類型銅礦床的成礦模型，以期為該區的找礦勘探和礦產開發提供理論依據。 -
It ' s the first time to explore the combustion characteristics of lpg / diesel mixing fuel engine, and find that, with the change of load and rotation, the changing trend of the ignition delay period of e10 mixing fuel is almost as identical as that of the diesel, but that of e30 mixing fuel is very different. comparing with diesel, the combustion of e10 is improved slightly, but that of e30 greatly changes ; the maximum eruptive pressure decreases ; the maximum pressure increase rate decreases ; the highest releasing heat rate increases ; the highest combustion temperature falls ; the ignition delay period extends
結果表明: e10混合燃料與柴油的著火滯燃期隨負荷和轉速的變化趨勢基本一致; e30混合燃料與柴油則有所不同; eio混合燃料發動機的燃燒與純柴油相比，略有改善; e30混合燃料的燃燒特性發生明顯的變化，最高爆發壓力下降，最大壓力升高率減小，最大燃燒放熱率增大，最高燃燒溫度下降，滯燃期延長。
