3) premade fragments
预制破片
1.
In this paper,the factors,such as fragments initial velocity,the mass and shape of a single fragment,the blasting height,impact angle and terminal velocity of the projectile and so on,which affect the lethality of premade fragments were analyzed,and the conditions,which make the lethal area largest,were calculated,and the theoretic gist for optimum design of the projectile were provided.
文中分析了影响预制破片杀伤威力的诸因素,破片初速、单个破片的大小和形状、弹丸的炸高、落角、落速等,解算使得杀伤面积达到最大值的条件,为弹丸的优化设计提供理论上的依据。
4) prefabricated fragments
预制破片
1.
Based on terminal ballistics, taking into account tactical situations andthe probability of kill given a hit, the paper provides a new method to calculate thelethal area of a projectile with prefabricated fragments.
利用终点弹道学理论，充分考虑了战术情况和命中时杀伤概率，提出了一种新的方法来计算预制破片弹的杀伤面积。
5) fireformed fragment

6) precast and prestressed concrete lining
预应力管片
1.
As for a new structure,it is necessary to explore the stiffness of precast and prestressed concrete lining for shield tunnels.
盾构隧道普通混凝土管片接头的抗弯刚度主要是通过现场试验确定,目前尚无现成的公式或者图表可遵循,对于预应力管片这一新型的结构型式则更有必要对其接头的正负转角刚度,为此进行了弯曲的预应力管片接头试验。
