When a strong tide is disturbed by submarine bedforms, its effect on surface drift, breaking criteria, as well as energy dissipation rate of short wind waves are discussed and for a particular case, these effects are estimated using available experimental formulae for drift speed
本文將phiilips & b ~ r ( 1974 )的理論應用於受地形擾動的強潮流場,探討該潮流場對表面漂流的調制和對風浪破碎臨界條件的改變,並進而討論潮流場對破碎損耗源項的影響,初步給出一個考慮了上述影響的、適用於短重力波的破碎損耗源項形式。Shortwave communication plays a vital role in long haul communications, on account of its unique merits such as low cost, convenience to be generated and strong resistance to damage
短波通信具有成本低、架設靈活、抗毀能力強等優點,在遠距離通信中起著舉足輕重的作用。The test results demonstrate that this prototype has excellent comprehensive performances such as small bulk, lower weight, high efficiency, high steady precision, fast dynamic response, wide range input voltage, good output waveforms, strong over - load and short - circuit ability, and strong function with different nature load and three - phase unbalanced load
試驗結果表明,該變流器具有體積重量小、變換效率高、靜態精度高、動態響應快、輸入電壓變化范圍寬、輸出波形質量高、過載與短路能力強、帶不同性質負載和帶三相不平衡負載的能力強等優良的綜合性能。The simulation shows that the valve throttle area should be little as possible but must be more than 40 % of pipe section area ; when the total length of pipe is same, and the flow quantity is enough, pipe before primary valve should be thin and long, and the pipe after primary valve should be thick and short, the upriver and downriver small pressure fluctuation will badly lead to waterdrammer pressure rising, and spending more time in establishing pressure and flow quantity
模擬表明,閥門過流面積在滿足大於管道截面積40 %的條件下應盡可能小;在管道總長一定並滿足流量要求的條件下,主閥前應採取長而細的管道,閥后則應採用短而粗的管道;上下游微小的壓力波動都會嚴重增大開關閥門引起的水擊,並使壓力、流量的建立需要更長的時間。Generally, the gravity introduced deformation of an optical lens with smaller aperture ( < ( 100mm ) within visible band is about ( / 20 even less than this value. for general optical lens, this error level can be entirely neglected. but for the high - accuracy optical system within extreme ultraviolet band, the error caused by gravity deformation will lead to imaging quality degradation
本文較為系統地介紹了光學鏡頭的裝配與調校方法,一般地講,在可見波段內,光學鏡片口徑較小( < 100mm )時,重力引起的變形一般/ 20左右甚至更小,對於一般的光學鏡頭這樣量級的誤差完全可以忽略,但在極紫外短波長的高精度光學系統中重力變形帶來的誤差會使光學系統成像質量下降。The use of wave packet to analyze the dynamics of quantum mechanical systems is an increasingly important method to the study of the classical - quantum correspondence. using the quantum gaussian wave packet analysis method, we calculate the autocorrelation function of the rectangular billiard, the peak positions of the autocorrelation function match well with the periods of the classical periodic orbits, which show that the period of the classical orbits can be produced by the time - dependent quantum wave packet method. we also discuss wave packet revivals and fractional revivals in the rectangular billiard, the results show that there are exact revival for all wave packet at each revival time. we find additional cases of exact revivals with short revival times for zero - momentum wave packets initially located at special symmetry point inside the billiard
利用波包分析量子力學體系的動力學行為在研究經典和量子的對應關系方面越來越成為一個非常重要的方法.利用高斯波包分析方法,我們計算了矩形彈子球體系的自關聯函數,自關聯函數的峰和經典周期軌道的周期符合的很好,這表明經典周期軌道的周期可以通過含時的量子波包方法產生.我們還討論了矩形彈子球的波包回歸和波包的部分回歸,計算結果表明在每一個回歸時間,波包出現精確的回歸.對于動量為零的波包,初始位置在彈子球內部的特殊對稱點處,出現一些時間比較短的附加的回歸As a important method for middle or long distance wireless communication, short - wave communication gains its recognition over again, for its long - distance and anti - destroy capability. but now more advance performances are expected
短波通信是中遠距離無線通信的一個重要方式,由於通信距離遠、抗打擊能力強、設備簡單等優點在近年來重新受到重視。To minimize short - term capital risk with modest capital growth over the long term through a higher weighting of investments in global debt securities to provide steady income and lower exposure to global equities to provide modest potential for capital appreciation
透過偏重投資于全球債券市場及較少比重投資于全球股票市場,為投資盡量減低短期資本波動。以維持穩定的資本價值及賺取平穩收益,同時亦提供若干長遠資本增值潛力。At the present time earthquake forecast focus on various phenomena of earthquake such as seismic - electricity, geo - stress, electromagnetic wave, etc. earthquake forecast based on anomalous infrasound is one of important methods because of the good corresponding relationship between the anomalous infrasound and earthquake
短臨地震預報是世界性難題,由於對地震機理知之甚少,所以目前的地震預報著重於研究與地震有關的各種現象,諸如地應力、地電脈沖、電磁波、測震等等。由於次聲波異常與大地震有很好的對應關系,所以它是重要的臨震預報方法之一。分享友人
