常見例句雙語例句The absence of protostellar cloud material and the low velocity of the stars shows they could not have been born relatively recently or sailed in from elsewhere in the galaxy.星系中缺少原恒星物質(zhì)雲(yún)團,而且其中的恒星運轉(zhuǎn)速度低,說明恒星不可能是在最近誕生的,也不會是從星系的其他地方飄然而入。huzhangao.blog.163.comThe two moons collided relatively slowly, according to the theory described today in the journal Nature. Such low velocity impacts do not produce craters or cause much melting.發(fā)表在《自然》襍志上的該理論認爲兩個月球的碰撞相對緩慢,這種低速碰撞不會引起火山或地殼熔化。A power converting circuit of H-bridge bipolar PWM control is designed to decrease the low velocity.爲了滿足系統(tǒng)對低速度的要求,採用了雙極模式PWM控制,竝針對其設計了低功率損耗的功率轉(zhuǎn)換電路。權威例句Since high money holdings correspond to low velocity, the graph is simply the mirror image of the theoretical chart above.FORBES: Has The Fed Lost Control?In recent tests at the company's Advanced Technology Centre in Bristol, a special liquid has been used to construct a material that is thinner than normal body armour and yet is able to stop a low-velocity bullet.ECONOMIST: Monitor: Fluid defences TheThe name might be a stroke of marketing genius, but if you started out with a business called HVLS (high velocity low speed) Fan Company, you might look for something with a little more sex appeal, too.FORBES: How Big Ass Fans Can Improve Life for Working People, Fix the Economy, and Help Solve World Health Problems. 返回 low velocity
