  1. By analyzing and generalizing minerogenetic and geological background, mineral constituent, rare - earth element, isotope and typomorphic feature of sulpurization mineral, finally, we made a conclusion that fankou desposit resulted from the hot spring eruption at the bottom of sea, it has a character of syngenetic sedimentary deposit, which was affected by the late hydrothermal superimposed and light rebuilding after it came into being, which is typical sedex bedded - controlled deposit

    通過對凡口礦床的成礦地質背景、礦物成分、稀土元素、同位素以及的黃鐵礦、閃鋅礦、方鉛礦標型特徵進行了分析總結,確定了凡口礦床是海底熱泉噴溢形成的,同時又受到後期熱液輕微疊加改造,屬于典型的sedex型層控礦床。
  2. And the dopping magneto - optical materials were constructed to better meet the demand for the properties of magneto - optical disk recording media materials, forming the series magneto - optical recording media materials and decreasing the making cost by the method of introducing the light and middling rare - earth into the tbfeco materials. the magneto - optical properties and compositions of the tb - fe - co series dopping magnetic - optical film materials were investigated. the results show that when small amount of adulteration element was introduced into the tb - fe - co, the magneto - optical properties of materials are increased. for example the kerr angle and the coercive force are both improved

    對輕、中稀土摻雜的tb - fe - co系列磁光薄膜材料進行丁磁光性能和成分的測試,結果表明:在摻雜元素含量較小時,摻雜后的tb - fe - co磁光材料具有較好的磁光性能, kerr轉角_ k和矯頑力hc都有所改善,摻雜元素的含量應嚴格控制,不能超過一定限度,一般一般摻入量應莊10at左右。
