有效 effective; valid; efficacious 采取有效措施 take effective measures; 這張車票3日內有效。 this train ticket is valid for three days.; 有效半徑 effective radius; 有效保險 insurance in force; 有效成分 active principle; active constituent; 有效范圍 effective range; limits of validity; 有效功率 effective power; 有效能 available energy; 有效時間 effective time; net time; 有效壽命 useful life; actual life; 有效數字 significant digit; significant figure; 有效載荷 payload
The outer dimensions should be such that maximum utilization can be made of the available storage space . 外壁的尺寸大小,應使有效的貯藏空間能達到最大限度的利用。
New boosters can increase the payload by 120 % 新型助推器能夠使有效負載增加120 %
New boosters can increase the payload by almost one order of magnitude 新型助推器能使有效負載幾乎增加一個數量級
The working chamber is rectangular so as to achieve the maximum of effective volume 長方形工作室,使有效容積達到最大。
Rotate the potentiometer p7 completely clockwise , p2 and p4 completely counter clockwise 使有效的p7完全地順時針旋轉, p2和p4完全地相反地順時針。
Cuboid chamber maximizes the effective cubage . microprocessor controller for temperature ensures a precise and reliable control 長方體工作室,使有效容積達到最大,微電腦溫度控制器,控溫精確可靠。
This course enables students to acquire thorough understanding of japanese grammar including morphology and syntax up to advanced level ( jlpt level1 ) , which is necessary for reading different kinds of sinological works in japanese 本課程教導同學全面理解日語文法,掌握高級程度的詞法和句法,俾使有效閱讀各類日本漢學著作。
The control precision of the slider with 2400mm effective stroke can reach 0 . 05mm . the properties of the position control system are not exigent , only the dynamic non - overshooting and the stable - state - precision are considered . the system has given out satisfactory result when used in practical engineering , 0 . 03mm position control precision has been achieved , on account of dead band , the performance of proportional valve is worse than that of servo valve , but some advantages of proportional valve has made it more fit for industrial control 系統方案采用重復性能(反向回差)好的比例方向閥,使有效行程為2400mm的滑塊控制精度達到0 . 05mm ,位控系統快速性要求不高,主要考慮系統穩態重復精度,此方案在實際工程中已經取得了滿意的效果,位置控制精度達到0 . 03mm ,可以取代同類產品中日本川崎重工的泵控系統。
The workable competition theory , on basis of this , defines workable competition to the equilibrium of the economies of scale and competitive vigor and considers the economy of scale is the only reason that the workable competitive market is different from the perfectly competitive market . following that the standards of workable competition leave some tracks of perfectly competition 以此認識為基礎建立起來的有效競爭理論,認為有效競爭是規模經濟與競爭活力的均衡狀態,規模經濟是有效競爭市場偏離完全競爭市場唯一的理由,從而使有效競爭的市場標準,帶有明顯的完全競爭市場的痕跡。
The reasons of wreckage of the reservoir are as follows : the inadequate , inefficient and outdated information about the reservoir , the lower anti - flood standard and the supervisor ' s ignorance of the reduction of reservoir capacity owing the a accumulated soils over years . so setting up the 3d model of danjiangkou reservoir : and mastering relevant information on water resources matter significantly not only to the dispatch and regulation of danjiangkou reservoir , but also to the forthcoming project of " water in the south to the north " 水庫失事的原因多為:水文資料不足和未及時掌握水庫有關的水文資料,信息滯后,選用的防洪標準偏低;運行多年,庫內泥沙淤積使有效庫容大幅度減少而管理者對此又未及時掌握等。可見建立丹江口水庫三維模型,及時掌握有關水文資料,不僅對丹江口水庫的調度和管理,而且對即將實施的南水北調都有著深遠的意義。
