ballistics造句
(1) Ballistics: Science of propulsion, flight, and impact of projectiles. (2) Were you setting up your own ballistics program? (3) Ballistics don't match, and his gun was never fired. (4) Based on conventional ballistics theory, the mathematical model of the ballistic trajectory which adopts low and high pressure chamber fire mode is established for the small cluster tear bomb. (5) Aim To study the influence of the terminal ballistics effects of bullets on the trauma. (6) Internal ballistics is coupled, the movement of projectile in and out of barrel are calculated together to avoid the loss of accuracy caused by splitting them. (7) A ballistics expert were taking evidence at the scene of the crime. (8) Ballistics are realistic, injuries are fierce and environmental damage, like Cliff Richard, is catastrophic and persistent. (9) Other evidence provided by ballistics tests and fibre matching sealed the case beyond doubt. (10) The weapons are undergoing ballistics tests to see whether they were used in the shootings. (11) Trajectory stability problems of intercepting tactical ballistics missile guidance are investigated by the Lawes Criterion. (12) Ballistics was used in the criminal case to determine the gun's firing capacity. (13) Terminal Ballistics deals with the impact of projectiles on a target. (14) A Soviet ballistics officer draws the rightconclusion -- that a satellite report indicating incoming U.S. nuclearmissiles is, in fact, a false alarm -- thereby averting a potential nuclear holocaust. (15) Arthur left Fred to it and lay on his back in his own bedroom, reading a book about ballistics. (16) Nuln is the home of the Imperial Gunnery School, where cannons are cast and artillerymen learn the arts of ballistics. (17) He will identify those two automatic pistols as weapons he test-fired at the Ballistics Lab in order to obtain exemplary rounds. (18) Then we establish the mathematical computation models of roll angle and pitching angle with the yaw angle ignored based on geomagnetism and ballistics theory.
