This article introduces briefly the process of design and characteristic of structure of db930 tube and discusses the main problems of technology and technique which was met during the manufacture and the measures having been adopted are emphatically. it discusses the solve measures in following six aspects : the filament current is too large, carbon deposits during the carbonizing of cathode, the capacitance between the first grid and the second grid is too large, transpiring happens inside the tube, the insulation resistance between the electrodes is too lower when the filament is on and the ability of bearing high voltage is too lower
本文簡略地介紹了db930的設計過程及其結構特點，重點論述了在試制過程中遇到的主要工藝技術問題及解決問題的措施，圍繞解決燈絲電流大、陰極碳化時積碳、一柵和二柵之間的電容大、管內蒸散、熱態時極間絕緣低、耐高壓的能力差等六個方面的問題進行了論述。3 ) on the basis of the geochemistry methods of cathodoluminescencean, strontium isotope, carbon and oxygen isotope, trace element, inclusion, etc, pleokarst mechanism have been deeply studied. pleokarst had been brought about in the meteoric water of earths surface, and mainly in the early hercynian movement
3 ）通過陰極發光、鍶同位素、碳氧同位素、微量元素和包裹體等地球化學手段，深入地探討了巖溶作用機制，認為發生於地表或近地表大氣淡水環境，海西早期是區內巖溶作用發生的主要時期。Mol l, artemisinin can be reduced via the hemin - catalysis and its original cathodic peak at - 1. 08v completely disappeared. the cathodic overpotential of artemisinin is decreased ca. 600mv. this process is verified by the fact that complex edta - fe can also promote the artemisinin reduction with decreasing the cathodic overpotential of artemisinin for 590mv. these results show that the reduction of artemisinin at the glassy carbon electrode is a catalytic process with the aids of hemin. hemin can greatly decrease the cathodic activation energy of the reduction of artemisinin and promote the decomposition of artemisinin
Mol l氯化血紅素存在下，青蒿素仍可被催化還原，陰極過電位降低了600mv 。配合物edta - fe具有類似氯化血紅素的催化性質，它降低了qhs陰極過電位590mv 。在這個體系中，青蒿素在碳電極上的還原是一個藉助于氯化血紅素催化的還原過程，氯化血紅素的存在降低了青蒿素還原活化能，促進了青蒿素的分解。2. considering current equipments and requirements for db935, the technics standard were made sure, including the cathode weld and carbonization, manufacture of the pyrogenation graphite grids, surface treatment, assembly and the exhaust after a lot of research and improvement
2 、根據公司現有的裝備條件和db935的要求，通過不斷探索和改進，確定了陰極焊接及碳化、熱解石墨柵極製造和表面處理、整管裝配和排氣等工藝規范。Compared with carbon, silicon nitride bonded silicon carbide has better oxidation resistance and bigger resistance ratio, which make it be a perfect line material of al electrolysis cell
在鋁電解方面，氮化硅結合碳化硅遠較陰極碳塊耐腐蝕、抗氧化、電阻率高，是理想的電解槽側壁內襯材料。Carbon nanotubes were produced in an electric arc discharge with an anode composed of carbon. the productions were studied in different current, voltage, helium pressure and diameter of anode and cathode sticks. oxygen and steam in helium were discussed. the proper condition of producing carbon nanotubes is included to make purification easy. 2figs., 2tabs., 6refs
採用石墨電弧法制備碳納米管，研究了不同電流、電壓、氦氣壓力以及不同陰陽極棒徑條件下碳納米管的生成情況，並討論了氧氣和水蒸氣的存在對碳納米管制備的影響，總結出制備碳納米管的條件，給以後的純化工作帶來方便.圖2 ，表2 ，參6The analytic results of the effects on the micromorphological structure of the film by the electrochemical condition ' s showed that the carbon is apt to improve the boundary combination between the scfs and the surface of the cathode and the seperation of the films, and that the micromorphological structure of the mpgcfs is greatly affected by the dring and the power voltage, which remarkably affluence ion move in swelling cathode film, and that higher temperature and concentration of cu2 + in the medium solution are also advanagable to the deposition of cu in scfs. the plot of deformation behavior of mpgcfs showed that the maximum strench ratio decreases and the brittleness increases due to the existence of the metal phase, and that the strengh trend of the composite films is fistly up and down followed with the content of metal phase because of the change of the role of the metal phase from acting as the physical cross - linking to weakening the films due to destroying the whole structure of the polymer
另外它作為基體的另一個突出的優點是制備的溶脹復合膜（ scf ）中的溶劑與電解液中的溶劑相同都是水，克服了以前膜內外不同溶劑之間擴散的問題，結果使得電流最終趨於一種穩態，因此可以更好實現用電化學條件來控制mpgcf的形態結構；硬質石墨材料的多孔的結構和石墨本身的結構性能特點使得碳作為陰極材料時有利於溶漲復合膜（ scf ）與電極表面的結合以及膜的剝離，因此是作為陰極的理想材料；電化學條件中的乾燥程度和電壓能夠明顯的影響離子在膜內的遷移，從而對mpgcf的形態結構造成較大的影響；而提高反應溫度和增大電解液中銅離子的濃度也有利於銅在膜中的沉積生長。Abstract : in this paper, the material requirements of li - ion rechargeable bettery, the deve - lopment and production status of the intercalated - li anode material, the intercalated - li ca - thode compound and li - containning electrolytes, the world - leading producers of li - ion rechargeable battery and its potential applications in microelectronics and electric automobiles are reviewed, and the market requirement for lithium carbonate is also forecasted
