根據經濟學界爭論的內容，我將這一階段劃分為兩個時期，前一時期（ 1985年? ? 1988年）理論界主要就企業股問題、股份制問題、資產經營承包責任制問題、國有資產的經營管理問題展開討論;后一時期（ 1989年? ? 1997年）討論的焦點有「科斯定理」與我國國有企業改革的關系，產權理論和重塑我國產權制度。文章第三部分描述了1997年以來國有企業改革的情況，在十五大精神指引下，我國國有企業改革繼續向縱深方向發展。這一階段理論界爭論的焦點有「現代企業制度」問題，國有經濟戰略調整問題以及對現實中出現的各種「經理行為」的解析。 -

To make pic ( particl - in - cell ) simulations. to set up models of guns and magnetic field and simulate them in the vacuum and plasma, respectively. we found that plasma held back part of space charge effects and improved trajectory of electrons. but beam would oscillate and became instable as accretion of plasma density. by simulating again and again, we draw a conclusion magic could n ' t work when plasma density was more by far than beam electron density. at last a four - stage depressed collector was simulated
建立電子槍和聚焦系統模擬模型，分別在真空和填充等離子體條件下進行模擬。發現填充等離子體能補償部分空間電荷效應，改善電子束包絡軌跡，提高電子的流通率，但是隨著等離子體密度的增大，束電子會出現振蕩不穩定性，遺憾的是通過反復多次模擬發現本文所用粒子模擬的代表性軟體magic無法用於模擬等離子體密度遠高於束電子密度的情況。
