Light ( field ) howitzer : in addition to direct fire , these cannon can fire ballistically ( there does not have to be a clear line to the target object ) 轻型（野战）榴弹炮：在直瞄射击的基础上，这些火炮能够进行弹道射击（不需要到目标物之间通视） 。
Make sure that they are spread out and at all times covered by tripods or pac ' s as they ( devastators ) are not suited to take direct fire and thus must be protected 确保它们分散开，并且随时收到三脚和行星突击母舰的保护，由于毁灭战舰不适合直接承受攻击，因此他们必须被保护。
Depending on the type of mortar , you may have from 2 to 4 kilometers worth of range from it , which allows for the mortar team to be well out of enemy direct fire while still supporting an attack via fire 根据迫击炮的种类不同，射程可从2到4千米，可以避开敌军炮火的直接打击而为友军进攻提供火力支援。
Then ballistic model is established and analyzed when gun direct firing . by utilizing the digital controlling system and laser launching system , laser simulates ballistic path when gun direct firing 利用光机电最新技术，在控制成本的基础上，设计数字控制模拟弹道系统，测定火炮状态，控制激光接发系统进行模拟射击。
Anti - aircraft cannon ( aa ) : these cannon have the same properties as anti - tank cannon ( direct fire only ) but rotate much more quickly ( the cannon can revolve and is fixed on a stationary base ) , and they can target aircraft 防空加农炮（ aa炮） ：这些加农炮与反坦克加农炮类似（只能进行直接瞄准）但是能够比反坦克炮更快的旋转方向（这种炮被连接与一个固定台座上能够绕轴旋转） ，同时它们能够瞄准飞机射击。
For the problem that on - line monitoring of primary air of direct firing pulverizing system ca n ' t be complete achieved , the chaotic properties of parameter change of two - phase flow in pipe is analyzed in the paper , according to the pressure difference signal of two - phase flow system 目前电站锅炉直吹式制粉系统的一次风气固两相流流动状态在线监测仍未得以实现，针对这一难题，本文首次基于管道内气固两相流差压信号对其流动状态变化的混沌特性进行理论研究。
The heavy weapons ( machine guns ， infantry cannons ， antitank guns and mortars ) were placed on the eastern edge of sapadni ; the two 105 mm batteries occupied fire positions to the south of the locality ， with the mission of furnish direct fire against the houses in the edge of rostov ， located 1 . 500 meters ahead 它的重武器（机枪，步兵炮，反坦克炮和迫击炮）部署在萨帕德尼东面边缘； 2个105毫米炮连则在这个地点南面占领了发射阵地，其任务是对前方1500米处，罗斯托夫边缘的房屋进行直接射击。
The icv provides protected transport for an infantry squad and direct fire support during the dismounted assault . the icv carries a 9 - man squad and retains the capability to provide effective supporting fire to the squad while it is dismounted . the primary design of the iav has two variants : the infantry carrier vehicle and the mobile gun system 美军装备的“斯崔克” icv ，是新组建的中型旅主要作战装备，能够完整的输送一个步兵班，驾驶员车长，及后舱的9名步兵，除可以提供行进中的保护外，还能为下车作战提供直接的火力支援，使用的顶置武器站可以根据任务而改变，可选择的武器： m2hb 12 . 7mm机枪， mk - 19 40mm榴弹机枪。
Abstract : the paper studied the initial investment , the running cost and the energy consumption of different kinds of refrigerators , a conclusion lsas drawn , that direct fired lithium - bromide absorption chiller is only used in the district of poor electricity and the coal boil is not made use of 文摘:通过对直燃型溴化锂冷温水机组和电动式制冷机组及蒸汽双效溴化锂吸收式制冷机组的技术经济比较，从机组的初投资、运行费用和能耗三个方面进行研究，得出的结论是：直燃型溴化锂冷温水机组只能在电力供应紧张和不允许采用燃煤锅炉的地区加以推广。
