另外,正是基於新的自然哲學的、作為描述機械運動的時空片段的「瞬」標志著古典數學原子論的積分觀向現代的分割實數連續統的積分觀的轉化,而現代數學的微分概念更是直接源於描述機械運動的速度和與運動軌跡密切相關的曲線的切線問題。With the use of finite method we have developed computer simulation software for vacuum microtriodes with wedge - shaped and cone - shaped cathode on the basis of stduying deeply the field emission theory of vacuum microelectronics. the software included field section, grid point numbering, and the calculation of electric currents, transconductance and cathode capacitance, moreover, it can simulate the properties of vacuum microeletronic with variant structures and sizes. the relationship was studied and simulated among electic properties and device structures, sizes and cathode materials etc. the optimized design of vacuum microtiode was proposed
本文在深入研究真空微電子器件場致發射理論的基礎上,根據圓錐形、楔形陰極真空微電子三極體的不同特點,分別建立了物理和數學模型,在考慮空間電荷密度影響的前提下,以有限元法為基礎採用迭代的方法計算出真空微電子三極體內的電勢分佈情況,繪制出了等勢線、電子軌跡線,並得到了器件電學性能隨幾何參數的變化情況。With the experiment part, the errors of sk - 21 nc machine tool have been measured, and a serial of data is gotten which lead to the error discrimination. ( 3 ) based on the kinematical theory of mbs, the calculation methods for the ideal center envelop curve of grinding wheel on cam grinding, the practical cutter track, inverse contour of cam, ideal nc instructions, precision nc instructions, the inner / outer normal and the fitting criterion of curve have been all discussed in detail in this paper
( 3 )通過精密加工的約束條件方程,探討理想刀具路線、逆變數控指令與實際刀具軌跡之間的映射關系,解決誤差補償技術提高加工精度的核心問題? ?當要求數控磨床的砂輪中心準確到達給定的理想點時,精密數控指令值究竟該是多少,如何能夠通過計算,獲得這樣的數控指令值,給出經修正的數控指令計算方法。Textiles - knitted fabrics - determination of stitch length and yarn linear density in weft knitted fabrics
