中文拼音 [suìpiānshǔmù]
碎片數目
英文
number of chunks-
The main simulation results were as follow : the average energy of electron decreases with the increasing pressure ; it decreases with the increasing methane concentration in the filling gas in the lower pressure range and increases in the higher pressure range ; the number density of fragment h and ch3 does not always increases with the gas pressure, but reaches an individual maximum ; energy carried by neutral dissociative fragment ch3 decreases with increasing gas pressure and ch4 concentration
主要結果如下:平均電子能量隨著反應室內氣壓的增加呈下降趨勢;在較低氣壓范圍內平均電子能量隨著反應源氣體中甲烷濃度的增加而減少;在較高氣壓范圍內平均電子能量則隨著甲烷濃度的增加而增加;隨著氣壓的增加碎片h和ch _ 3的數目並不是一直增加的,而是在不同的特定氣壓下出現各自的最值;碎片攜帶的能量基本隨甲烷濃度和氣壓的增加而減小。Air force space command data show that when the kill vehicle impacted the target satellite, debris was ejected from the impact point at velocities of up to 1, 400 mph. ( 2, 000 fps. )
美國空軍空間指揮中心的數據表明,當攔截器撞擊目標衛星時,碎片會以每小時超過1400英里(每秒2000碼)的速度從撞擊點飛散出去。Smaller block sizes reduce the amount of internal fragmentation within files and directories and are more space efficient
較小的塊尺寸減少了文件和目錄中內部存儲碎片的數量,空間利用率更高。After the analysis of space debris sources and components, various factors, which result in debris number increase or decrease, are investigated in detail
本文主要研究內容如下:首先,對空間碎片的演化機制進行研究,在分析了空間碎片的來源和組成之後,對導致空間碎片數目增加、減少的各種因素進行了詳盡的分析。分享友人
