  1. 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

    建立電槍和系統模擬模型,分別在真空和填充等離體條件下進行模擬。發現填充等離體能補償部分空間電荷效應,改善電束包絡軌跡,提高電的流通率,但是隨著等離體密度的增大,束電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模擬的代表性軟體magic無法用於模擬等離體密度遠高於束電密度的情況。
  2. This dissertation present a new structure of rbwo and use the magic tool to simulate it and it is a good reference for further research on improving output power, efficiency and reducing the focusing magnetic

    本文的研究工作提出了一種hl - rbwo的結構並對其進行了模擬;在思想方法上,在如何提高rbwo的輸出功率、輸出效率、降低磁場,對于研究進一步開發和利用高功率高效率低磁場微波源有一定的參考意義。
  3. This dissertation presents a way to improve the efficiency and output power of rbwo and to reduce the focusing magnetic of the rbwo. in order to verify the correction of this method, i use the particle - in - cell ( pic ) software magic to simulate the rbwo of this kind of structure

    本文研究了提高x波段rbwo輸出功率和輸出效率、降低磁場的方法,提出了一種新結構的hl - rbwo並對其進行了計算機的模擬驗證。
  4. Blinking of the sers spectra and the poisson statistical distribution of the raman signal were observed. moreover spectral diffusion of raman shift with time was reported by the first time according to our knowledge, which could be due to the difference of interaction between varied single molecules and varied silver particles surface, for instance, due to the different adsorption states of dab molecules on the silver surface, which should be a powerful evidence for single molecule detection by sers

    我們採用一種簡單的方法,將含有dab分的銀膠體溶液滴在鋁箔上,激發光在液滴上直接進行測量,觀察到了分sers信號的「 blinking 」現象,並首次報道了其sers拉曼頻移隨時間產生波動,這是由於個體分和銀納米顆的相互作用及其在銀納米顆表面的l吸附狀態不同而導致的。
