  1. The sod activity in s. maltophilia 276 increased rapidly during the bacteria growth at early log phase, and reached highest with 570 units / ml of cell extract ( from 10 ml of cell culture ) at the end log phase of bacterial growth. the sod activity decreased when the bacteria entered growth of stationary phase. it was clear that the production of sod by s. maltophilia276 was consistent with the growth of bacteria

    Maltophilia276菌株對數生長前期， sod的活性迅速增強；到對數生長後期，其活性達到最大，此時每毫升該細菌培養液的sod含量達到570iu （酶活力單位） ；在細菌進入生長穩定期后， sod的活性開始下降，這就說明276菌株所產生的sod活性同該菌的生長量是一致的。
  2. The paper consist of three parts as follows : 1. the method to calculate formation pressure : the method to calculate formation pressure in this paper is based on the equivalent depth technique, and it extract log characteristic parameters based on log ' s auto - separating and the lithology recognition. the automatization and precision of formation pressure calculation are upgraded

    地層壓力計算技術：以等效深度法為基本原理，輔以測井曲線自動分段和巖性識別基礎上的測井特徵參數提取，建立了本論文所採用的地層壓力計算技術，提高了地層壓力計算的自動化程度和計算精度。
