- antenna rotation period 天线旋转周期
- Yet the March 1979 burster, with an apparent rotation period of eight seconds, was spinning much more slowly than any radio pulsar then known. 但1979年3月那次的爆炸源，看起来却有八秒的周期，自转速率要比当时所知的任何波霎还要慢得多。
- At the top of the huge ship radar tracking and measuring antenna rotation slowly, firmly pointing to the "Shenzhou" spacecraft will be flying out of amlodipine direction. 船舶顶部巨大的雷达跟踪测量天线徐徐转动,牢牢指向了“神舟”号试验飞船将要飞出地平的方向。
- But the statistics analysis show the distrbution of corona activity of late type with color index and rotation period exist upper limit. 演化恒星的磁冕球活动在色指数和自转周期的分布上都显示出冕球磁活动存在上限的现象，并且对冕球磁活动上限的拟合表明在色指数B一V为1.;0附近和自转周期!
- An area near the rim of Shackleton crater, for example, is illuminated for more than 75 percent of the lunar rotation period. 例如夏克顿陨石坑边缘附近的一块区域，在月球自转周期中超过75%25的时间都受到日照。
- cross - antenna rotation andinversion (CARI) 天线旋转取反法（CARI）
- Antenna Rotation and Target Control 天线旋转与目标控制
- The antenna rotates but has phased arrays on both sides so it can search two sectors at once. "大鸟"雷达的天线会旋转，但它的两面都有相控阵，因此它可以一次性搜索两个方向。
- Measuring the body rotation period with data set 用数字式测定仪测定物体的扭转周期
- In addition to its geographical features, Mars' rotational period and seasonal cycles are likewise similar to those of Earth. 除了它的地理特征，火星旋转期和季节性周期，也同样的那些类似的地球。
- There have good linear relativity between stellar magnetic activity, rotational period and stellar age of MS stars, but this relativity of evolution stars has different action. 在第七章中，我们讨论了晚型恒星的自转周期的分布、恒星年龄对晚型恒星磁活动的影响以及晚型恒星的角动量演化。 晚型主序恒星的自转周期、磁活动与恒星年龄之间存在很好的线性相关性。

- That period was a bright page in the history of Chinese literature. 那个时期是中国文学史上光辉的一页。
- Reception improved because of the new antenna. 接受效果因有新天线而得到改善。
- Let us hope that the period of this injustice will be over soon. 让我们希望这个不公正的时期很快结束吧。
- These disturbances, which tend to recur in phase with the sun's27- day rotational period, are set off by the interaction between fast solar winds emanating from holes in the corona and slower winds arising from the sun's equatorial streamer belt. 这种地磁扰动随著太阳27天自转周期重复发生，其成因是从日冕洞喷出的快速太阳风，以及从太阳赤道流出的较慢太阳风，互相作用所致。
- The seasons follow each other in rotation. 四季循环交替。
- Childhood is a period of rapid growth. 幼年是生长迅速的时期。
- He consulted the chronicles of the period. 他参考了这一时期的编年史。
