查询词典 force of gravity

Which may be strange coming from a Science-Fiction writer - But right now, you and me here, put together entirely of atoms , sitting on this round rock with a core of liquid iron, held down by this force that seems to trouble you, called gravity , all the while spinning around the sun at 67,000 miles an hour and whizzing through the milkyway at 600,000 miles an hour in a universe that very well may be chasing its own tail at the speed of light; And admist all this frantic activity, fully cognisant of our own eminent demise - which is our own pretty way of saying we all know we're gonna die - We reach out to one another.

听一个科幻小说作家说这话会觉得挺奇怪的——可是就像现在，我和你，都是由原子组合起来的两个物体，坐在这个铁水核心的圆形岩石上，被这种困扰你许久的动力拉扯着，与此同时我们还在以每小时六万七千里的速度绕着太阳旋转，以每小时六十万里的速度穿梭过银河，而这个巨大的宇宙说不定不过是在用光速追逐着自己尾巴的一个循环。抛开这些疯狂的状况不说，我们还都很清楚自己迟早有一天会寿终就寝——说白了就是我们知道自己早晚会死——尽管如此我们还是张开双臂接纳彼此。

On moving base, a new initial alignment algorithm for strapdown inertial navigation system is proposed. In the algorithm, two special inertial frames, the initial-time inertial frame (i0 frame) and the initial-time SINS body inertial frame (ib0 frame), are defined and are selected as calculation reference frames, then, the calculation of initial alignment direction cosine matrix is expanded into three parts:(1) the DCM between i0 frame and the navigation frame will be easily obtained via local geographical coordinates and initial alignment time;(2) attitude updating using gyro samples gets the DCM between SINS frame and ib0 frame;(3) by explaining SINS specific force equation in SINS body frame, the relation between velocity log, accelerometer measurement and gravity acceleration is established to achieve the constant DCM from ib0 frame to i0 frame.
