1 ¹ìµÀÆ¯ÒÆ£¨Æ«ÒÆ£© Àý¾ä£ºIn this paper, the common rule of sun synchronous orbit satellite orbital excursion was obtained by analyzing the actual orbit data of FY 1C, the first generation polar orbital meteorologic satellite in China, and a simple but effective method to estimate the excursion of satellite orbital nodical local time was also presented. By contrasting actual excursion of FY 1C, the method was analyzied and amended. ¸ù¾ÝÎÒ¹úµÚÒ»´ú¼«¹ìÆøÏóÎÀÐÇ"·çÔÆÒ»ºÅ"C(FY 1C)ÐǹìµÀʵ¼Ê¹Û²âÖµ,·ÖÎöÁËÌ«Ñôͬ²½¹ìµÀÎÀÐǹìµÀÆ¯ÒÆµÄÒ»°ã¹æÂÉ,Ìá³öÁËÒ»ÖÖ¼ò±ãÓÐЧµÄÎÀÐǽ»µãµØ·½Ê±Æ¯ÒƹÀËã·½·¨,²¢ÓÃFY 1CÐÇʵ¼ÊµÄ½»µãµØ·½Ê±Æ¯ÒÆÁ¿,¶Ô¸Ã·½·¨½øÐÐÁË·ÖÎöºÍ¸Ä½ø¡£ 2 ¹ìµÀÖ±¾¶ Àý¾ä£ºMicrotitration plate shaker capable of a minimum speed of 500 rpm with an orbital diameter of 1-3 mm. |

ÕâÀïÊǵڶþ¾äµÄÎÄÕªÀý¾ä£º In the flume experiment,ripples were produced by nine kinds of regular waves and wave groups of different periods and wave heights. The ripples existed from the mouth of the flume to 4. 5-- 4. 8m upward,with the upper limits at the bases of the swash zones. The scales of the ripples varied with the periods of waves. The ripple wavelengthes (A) decrease from the sea to the land, but the ripple heights (n) and symmetric indexes (SI) decrease gradually. The ¦Ë/a0 (a0 -- orbital diameter of nearbotto...
