synodic period meaning in English
会合周期
Examples
- The time between successive new moons , the synodic period
两次新月之间相隔29 . 5日，这个盈亏周期称为 - Its synodic period brings it into conjunction with the sun every 398 days and 88 minutes , a little more than a year
它与太阳关联的会合周期是398天零88分，比一年稍长一些。 - Is 29 . 5 days . interestingly , the rotational period of the moon relative to the sun is exactly the same as the synodic period
盈亏月。月球的自转周期刚好和它的绕地公转周期相等，这种情形称为 - 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。 - We had observed more than ten selected asteroids using 1 - meter telescope in yunnan observatory during 2000 to 2002 . the observational data of seven asteroids had been reduced and analyzed . we have derived their synodic periods and estimated the shape and orientation of rotational axis for one asteroid
为此，我选定了一些直径在125公里左右的小行星进行观测和分析；一方面，测定它们的自转周期，进行“角动量衰减”现象的研究，另一方面，对小行星形状和自转轴指向进行估算，为小行星碰撞演化研究提供更为有利的证据。
