particle gun-
The main works of the dissertation are listed as following : fist, know the theorical basis and software use of egun, magic. represent the theory and calculation method of electron optics
本文主要工作如下:掌握egun 、 pic粒子模擬程序兩種軟體設計電子槍的理論基礎，熟悉軟體使用，闡述電子光學系統的基礎理論與計算方法。In order to make the most of this startling sound, village children used bamboo sticks to make toy guns, and the unripe fruits of pop - gun seed were used as bullets
從前的村童利用竹枝作槍桿子，拿逼迫仔未熟的果實當子彈。于槍筒口塞入一粒果實，再用一支較幼的竹子插入槍筒另一端。Static removal lonizing air gun / hs static removal lon - izing air nozzle lonizing air gun / nozzle is a kid of effective static removing instrument, which swiftly blows the great deal of cation and anion occurred in the ion occurring in - strument with high pressure airflow to the area to be re - moved the static, neutralizes the static charge clooecting in the object, at the same time, high speed ion airflow blows off the dust attracted by static, and prevents it to attract dust again
離子風槍/風嘴是一種高效的靜電消除裝置，通過高壓氣流將離子發生裝置所產生的大量正負離子迅速吹向所要除靜電的區域，中和物體上所積累的靜電電荷，同時，高速離子氣流將靜電吸引的塵粒吹除，並阻止其再次吸收塵埃粒子。The pen gun looks like a conventional pen, but can fire a. 22 - calibre bullet that can kill someone within a range of two metres. key : 1
筆型手槍的外型及大小與普通鋼筆無異，但每次可發射出一粒點二二口徑的子彈，在兩米范圍內，置人于死地。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。Hsp70, a kind of molecular chaperone, has the main functions of taking part in protein folding, protein degredation and reparation of dna damadge and has important effects on the constructure and function of mitochondria. it has already been proved that there is a close correlation between hsp70 and the development of plants and animals. this paper deals with integrating sense and antisense cdnas of hsp70 into tobacco dna by constructing an expression vector of sense and antisense cdnas of hsp70 and gene - transforming methods - genegun bombarding and agrobacterium mediation. provided expression of hsp70 gene is inhibited by sense and antisense cdnas of hsp70 we can get male sterile plants so as to prove that antisense cdna of hsp70 leads to male sterility 1
Hsp70是一種分子伴侶，主要功能是參與細胞有關蛋白新生肽的折疊、亞基組裝、細胞內運輸、蛋白質降解及dna損傷的修復，對線粒體結構和功能發揮重要作用，已有研究證明hsp70與動植物的發育有密切的關系，本研究將hsp70正、反義cdna構建成表達載體，並運用基因槍和農桿菌介導法將hsp70正、反義cdna導入煙草，試通過hsp70反義cdna抑制hsp70基因的表達從而創造雄性不育株，以證明hsp70反義cdna能創造雄性不育系。分享友人
