  1. Environmental element includes illume not beautiful, be read undesirably and work habit, if be read for long, work with close quarters, the adjustment of the eye muscle is in persistent nervous and contractive condition, adjust then ability is abate, and produce myopia

    環境因素包括照明不佳，不良的閱讀和工作習慣，如長時間閱讀和近距離工作，眼的調節肌肉處于持續的緊張收縮狀態，進而調節能力減弱，而發生近視。
  2. Yet, most existing high speed on / off valves use electromagnet as their electicity - mechanism conversion element, and good performant electromagnets have to be imported from other countries, in such situation, it is difficity to make excelent high speed electromagnet valve made in our country, even if we can make good performant high speed electromagnet valve in our country, it still has the shortcoming of not high enough respond speed, too small placket and big volumeo in this thesis, a new high speed on / off valve is developed based on two types of existing valves, this new valve has higher respond speed, a little big placket and little volume o for the new valve, several main task was made out as below : a ) several types of high speed on / off were first analyzed, then the basic performance of the actuator of the new valve was analyzed

    高速開關閥是20世紀80年代發展起來的一種具有響應速度快、抗污染能力強、與電子電路配合好等特點的一個良好的動力放大元件。但是現有的高速開關閥基本上採用電磁鐵為電?機轉換元件，高性能的電磁鐵又基本為進口，難以滿足高性能高速開關閥國產化的要求，即使是高性能的電磁鐵式高速開關閥，仍存在著響應速度不夠大、開口過小、體積較大的缺點。本文在現有兩種高速開關閥的基礎上，設計了一種新穎的高速開關閥，在提高其動態性能的同時，增大了閥的開口，減小了閥的體積。

  5. 5, such results as the list of the reaction force, deformation figure of the truss the contour of the nodes displacement, the contour of the element stress, and the contour of the node stress, are attained under the static force, the analysis of the finite element show that the maximum stress reaches the value of 285mpa, and then the frame body has the larger stress concentration in this position, if the welding around is not adopted

    通過ansys5 . 5軟體有限元分析，得出了各支座反力和節點應力列表，以及桁架在靜力作用下的變形圖、節點位移等值線圖、單元應力等值線圖、節點應力等值線圖。有限元分析計算表明，在不採用周邊焊的情況下最大應力可達285mpa ，具有較大的應力集中。
