ball firing 實彈射擊。

ball game

In the dissertation ' s chapter 3 to chapter 5 , the mechanical and physical performances of the engineering plastics are analyzed , the failure mode and the designing computing methods of engineering plastics member suffering the static load , dynamic load , impact load , pulse load , are studied . by the practice application and ball firing experiment of the engineering plastics key piece in the weapons , the precious experiences , for engineering plastics application and confirmation of the material performances guideline in the weapons , are obtained 論文的第三章至第五章,分析了工程塑料物理機械性能,研究了受靜載荷、動載荷、沖擊載荷及脈沖載荷下工程塑料構件的失效模式和設計計算方法,通過工程塑料在槍械關鍵受力結構件上的實際應用和實彈射擊試驗,取得了寶貴的經驗,為高性能工程塑料在槍械上的應用和材料性能指標的確定奠定了基礎。

This testing instrument ' s successful development , not only did we know fairly well before shooting range ball firing , but it can instruct manufacture of artillery , make assure the quality of every artillery , save a great deal fund 坦克炮管靜態定向精度測試系統的研制成功,不但可以在靶場實彈射擊前做到心中有數,而且能夠指導火炮的生產,保證每門火炮的質量,節約大量資金。

In the following small game , the players task is very simple , namely the control of the ball firing in the direction of their goal into the corner 在下面的小游戲中,玩家的任務非常簡單,即控制射球的方向,將其打入球門的死角。
