  1. 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。
  2. Soil : investigation and testing. atterberg limit determination. part 1 : liquid limit. cone penetrometer method

    土壤:研究和試驗. atterberg極限的測定.第1部分:液體極限.錐入法
  3. However, both of them have disadvantages. mo tip feas is fabricated by evaporating tip cathodes on base, so it has bad coherence with the base. on the other hand, the characteristics of silicon result in the bad heat stability, bad emission reliability, and low current density

    然而，這兩種陰極存在各自的缺點，如鉬尖錐是蒸鍍在基底上的，所以與基底的附著力不強;而硅的特性又決定了其熱穩定性差，發射的可靠性低，發射電流有限。
  4. The illustration is by hand to express, quote from this literary reference of “ the head hangs the beam, the zhui stabs ” of ancient times, but the ancients cloud : " in the book there is gold house ", an monster is binding the hair to try very hard to studying on the ceiling, there is a large number of gold ingot in front of him, but his is die of have eyes fixed on this gold, still stay the exit water in mouth, take the irony meaning, deliver the deep province of person, attack current education system in china not perfect, the examination is hardly limited the student ' s imagination and creative ability

    用手繪插畫的形式來表現，引用了古代「頭懸梁，錐刺股」的這一典故，而古人云： 「書中自有黃金屋」 ，一個怪人正把頭發綁在天花板上拚命讀書，在他面前的是一堆金錠，而他的眼睛正在死死的盯住這堆黃金，嘴裏還留出口水，帶有諷刺意義，發人深省，抨擊了中國現行的教育體制的不完善，功名考試極大的限制了學生的思維和想象力。
