最后,利用数值实验验证了方法的有效性。同时,我们给出了脉冲周期的一个估计上界。 - Due to their large masses , their rotational periods are very regular . we can specify the periods of some pulsars up to more than ten decimal places . this allows us to study the small disturbances around the star
由于中子星非常沉重，所以它的自转周期非常规律，有些中子星的脉冲周期可以准确至小数后十个位，因此，就算中子星出现轻微的异动，天文学家亦可以观察得到。 - For example , if there is a planet orbiting around the neutron star , it will wobble a little and the pulses will come a little early or late . we can then deduce the mass and the radius of the orbit of the planet from the arrival time of the pulses . this is how the first extrasolar planet is discovered
例如假若有一颗行星围绕一颗中子星运行，它会令中子星出现摇动，引致脉冲的间隔变长或短，由此我们根据脉冲周期的变化，可推断出行星的质量和轨道半径，这亦是天文学家找出第一颗地外行星时所用的方法。 - This system is realized by cpld which can get rid of the disadvantages in one - time design including property liable to jamming , long sampling period , and poor working stability . its sampling period is up to 500ns at least and output delay is only 19 . 5ns . a stable period of pulse coming out of quadruple - frequency differential circle belongs to it
完成了用vhdl硬件描述语言对全数字转速位置测量子系统的设计，并用max ? plusii软件进行了编译和波形仿真，在cpld ( max7000 )得到实现，该系统克服以往设计中存在的易受干扰、工作稳定性差、采样周期太长等的缺点，输出延时仅为19 . 5ns ，采样最低周期可达到500ns ，且四倍频微分电路获得的脉冲周期稳定。
