  3. A method based on the application of an injection process analysis software is introduced in this article, which optimize injection process through changing the design of fuel - injection pump cam. a model of 1115 single cylinder direct injection diesel engine is used as an example. with the help of pre - journey optimization, increasing cam lift and using tangent - function can make the matching of the injection system with the diesel more reasonable. without changing fuel pump installing size, it can enhance injection rate and injection pressure and improve the diesel operating stability in low speed condition

    本文以國產1115型單缸直噴柴油機為例，介紹一種應用噴油過程分析軟體改進噴油泵凸輪設計的方法，通過增大噴油泵凸輪升程、採用切線函數凸輪並優化預行程的方式，在不改變噴油泵安裝尺寸的前提下，可提高噴油壓力和噴油速率，改善柴油機低速工作穩定性，使噴油系統與柴油機匹配更合理。
  4. For example, high - lift ( low speed / high angle of attack ) performance may be required as well as low - lift ( high speed / low angle of attack )

    例如高揚程（低速/高攻角）表現以及可能需要低揚程（高速/低迎角）
  5. 1. after a series of comprehensive testing and structure analysis to various bridges on the guangshe, huning, jinqin, shenshan, jingguang. ln our opinion, the key problems of the railroad bridge are as follows : ( 1 ) bridge construction is not well at the request of the railroad train speed - lift, primarily because of low dynamic property of the horizontal frame ; ( 2 ) the bad liability of the bridges structure, concrete beam ' s horizontal plank coupling form ; the low capacity of some of the bridges

    在對廣深、滬寧、京秦、沈山、京廣干線上不同橋梁結構進行的一系列綜合試驗的結果分析后認為，我國鐵路橋梁目前存在的主要問題為：橋梁結構不適應列車提速的要求，主要反映為結構橫向的動力性能較差；橋梁結構的耐久性問題；混凝土梁的橫隔板聯結方式；部分橋梁承載能力不足。
