Here we assume planets move in circular motion at constant speed , and the synodic periods given above is just an approximate value . actually the planetary motion is full of small variants , and the synodic period values are irrational number . the quotient of two irrational numbers cannot be written as a fraction 最新的消息是,在2000年10月后的六星期内,竟然一口气为土星多发现10颗卫星,让它在刹那间重新超越天王星,成为最星多势众的行星,现在土星有28颗卫星,遥遥领先只有21颗卫星的天王星,木星的卫星数目为18颗,而第四位的海王星则只有8颗。
From the study results it is showed that turret hole position near the forward of the midship has less effect to the ship girder strength and it is more reasonable using probabilty statistics method to estimate the extreme value of wave bending moment , by which the first approximate value of hull midship section modulus can be determined 研究结果表明:转塔开孔位置在舯前附近对船体总强度影响不大;波浪弯矩极值用概率统计方法估算更为合理;船体结构剖面模数的第一近似值可用波浪弯矩设计极值等来确定。
It also calculates theoretically the minimal time interval between two trains in quasi - moving - block signaling system and recommends approximate values for the length of coded digit track circuit . the rapid development of urban rail transit demands a deep understanding on the features of track circuit 在此基础上,针对当前应用广泛的基于数字轨道电路的准移动闭塞atc系统进行了重点分析,详细讨论了数字轨道电路的原理、准移动闭塞系统的列控方式等内容,并对准移动闭塞下的最小列车追踪间隔时间进行了理论计算和分析,给出了数字轨道电路长度的推荐值。
