機尾渦流可以在無風的空氣中停留幾分鐘,向後延伸達12公里,所以美國聯邦航空總署按照飛機大小而規定了飛機之間的最小安全距離。This system employed a new concept for measuring upper winds, viz. use of vlf very low frequency in the range of 10 - 13 khz signals from a global navigational network, omega, for computing the wind
與以往無線電相比,該系統在測風方面則採用了一種新的概念,利用世界性奧米茄導航站網的甚低頻信號10 - 13khz來計算出高空風向和風速,無需用雷達追蹤探空儀位置。Measurement of pressure, temperature and humidity operated in much the same principle as the older version of radiosonde, but computation of wind was made use of the vlf ( very low frequency in the range of 10 - 13 khz ) signals of a world - wide navigational network, omega
該系統量度高空氣壓、氣溫及濕度的方法與舊式無線電探空儀大致相同,但在測風方面則採用了一種新的概念,利用世界性奧米茄導航站網的甚低頻信號( 10 - 13khz )來計算出高空風向和風速,無需用雷達追蹤探空儀位置。So, our team had not the chance to move horizontal on the mast when the ship was moving. about the 1, 200 meters running, the way was not clear and there is no enough instructors or staffs to direct the 36 trainees, it resulted in most trainees lost the way and failed to finish the 1, 200 meters that included me. according to the environment, city challenge instead of field challenge, camp on beach replaced sole stay in mountain, the tend of wind delayed the sailing schedule and it cancelled the raft race, it took away our opportunity of learning how to make raft by bamboo and large plastic tub
首先是船頭跳水,在港,正好鯊魚旺季,暫停營業,到了日本,又逢港口管制,被逼休假;而離港啟航的首個節目,本應是在行進的船上,爬上桅桿,再橫行桿上,學習解帆,雖然桿是上盡了,但雨卻落下來,船要轉帆,於是橫行桿上學習解帆這等壯觀場面,我們全組都無緣參與;再來是千二米長跑,指示不清,路線不明,以致多人迷路,被逼半途而廢;接下來的野外定向,因就地利,變身為城市挑戰;山中獨處換了沙灘露宿;風向延誤了航程,阻止了木伐競渡。For my part, i was never so sensible of danger in my life ; for seeing above three hundred devils come roaring and open mouth d to devour us, and having nothing to shelter us, or retreat to, i gave my self over for lost ; and as was, i believe, i shall never care to cross those mountains again ; i think i would much rather go a thousand leagues by sea, though i were sure to meet with a storm once a week

在最優控制的求解中,提出了向風坐標系轉化、無量綱化等解前分析的思想,簡化了計算,方便了加權因子的選擇,使目標點可達與不可達的翼傘系統歸航軌跡最優控制問題得到了統一的求解。分享友人
