  4. Following this, a new phenomenological eos along isotherms that may be used at high pressures for nacl - type and cscl - type alkali halides, metals, periclase ( mgo ), rare - gas xenon solid, and so on, is presented, by making use of the definition of short - distance repulsive force constant ( a ) and the phenomenological function a ( r )

    在此基礎上，從短程排斥力常數a的定義，及其與原子間距r唯象函數出發，提出一個可應用於相對高壓下的新的等溫固體物態方程，並對它的有效性和應用性進行了研究與討論；本文還在實驗數據的基礎上，運用了等壓過程中anderson - gr （
  5. By means of static and dynamic experiments, lots of research on the effect of micro - quantity heavy metal ions ( hmi ) removal by weakly basic anion exchange resins ( wbaer ) from drinking water ( dk ) with alkali metals, alkaline - earth metals and anions at high concentration, has been done

    本文採用靜態和動態兩種試驗方法，對弱堿性陰離子交換樹脂在堿金屬、堿土金屬離子以及陰離子相對較高濃度的背景下去除飲用水中微量重金屬離子（以hg2 +為研究處理對象）的效果進行了大量試驗研究。
  6. In a word, wbaer can effectively remove micro - quantity hmi from dk with alkali metals, alkaline - earth metals and anions at high concentration. on the basis of lots of regeneration experiments of wbaer ( d301g ), the best regeneration manner ( regurgitation regeneration ), the optimal regeneration agents ( h2so4 and naoh ) and the optimum operating parameters of regeneration are obtained
