繞射現象 的英文怎麼說
中文拼音 [ràoshèxiànxiàng]
繞射現象
英文
diffraction phenomenon-
And our demo nicely shows the motion of water waves : reflecting, intervening, circumambulating
實驗結果表明，水波的運動是逼真的。我們成功地模擬了水波的反射、疊加和繞射現象。In this paper, we do research about the nonideal scattering centers
本文的研究圍繞各種非理想散射現象而展開。The computer speed is speeded up. the numerical results of the present models are in agreement with the theoretical solution and those of physical models. systematical numerical tests show that the present models can reasonably simulate the wave transformation, such as shoaling, refraction, diffraction, reflection, effect of currents and so on
比較詳細的模型驗證與應用表明，模型的數值模擬結果與解析解、物模實驗值吻合良好；可以較好地模擬波浪傳播過程中的淺水變形、折射、繞射和反射等多種現象；能正確合理地反映水流對波浪傳播的影響。The effects of waves transformation, refraction, diffration, reflection and breaking are all due to the depth of water, varying topography, bottom friction, obstacles and current as waves proceed from offshore to near shore regions. some basic parameters which are relevant to the cost of buildings as well as the type of structures are determined by the wave factors since these projects are placed in near shore area, so it is of great importance to study the regularity of wave transforming
外海波浪傳入近岸淺水區受水深、地形、底摩擦、障礙物以及水流等因素的影響，會發生變形、折射、繞射、反射和破碎等各種現象，然而大部分海洋及海岸工程位於近岸地區，該地區的波浪要素將是確定工程造價、建築物型式等最基本的參數，因此研究近岸地區波浪的變化規律具有重要意義。The land clutter is useless signals for target detection caused by land terrain. the multipath effect is some kind of interference which is caused by wave reflection on terrain. the diffraction effect is the phenomenon of wave propagation into shadow region
地雜波是由地面散射引起的對目標探測無用的信號;多路徑是由電磁波在地面反射所引起的干涉;衍射則是電波繞射傳播到遮蔽區的現象。As surface waves propagate from deep to shallow water, the wave will take series of transformation including shoaling, refraction, diffraction, reflection, breaking and energy dissipation due to the effect of topography and various hydraulic structures
波浪由深海向海岸傳播過程中，由於地形和水工建築物等因素的影響，將發生淺水變形、折射、繞射、反射、破碎以及能量耗散等波浪變形現象。The numerical model is tested by computing wave field for several examples of laboratory experiment, and agreement between model results and available experimental data is found to be quite reasonable, which demonstrates the model ' s ability to simulate wave shoaling, refraction, diffraction and reflection
用多個實驗地形對本文模型進行了驗證，計算結果與實測數據吻合很好，反映了本文模型可以較好地模擬波浪傳播過程中的淺水變形、折射、繞射和反射等波浪變形現象。Finite difference method can deal with regular boundary conditions. in this paper, we discrete the water domain into rectangular meshes, and simulate the propagation, reflection and diffraction of water waves. we just specify waves source, the movement of water waves can be simulated automatically
有限差分方法能夠處理具有規則邊界水域的水流現象，在本文中，我們把求解的水域離散成結構矩形網格，對水流的折射、反射、繞射等水流現象進行了動畫模擬，我們僅僅指定產生水流動畫的波源，水流動畫的細節均由數值方法產生，不需要人工的干預。They found two events showing the shortening of pulsating cycle and decaying of radiations intensity. the signatures matched theories of what scientists would predict to see. when matter is falling so close to the event horizon, it will be circling the black hole with increasing speed and its light will rapidly dim as it is stretched by gravity to ever - longer wavelengths
研究人員分析了極大量來自緻密天體天鵝座xr - 1的紫外線輻射，發現其中兩組數據顯示，輻射脈沖的周期隨時間縮短，而其強度則隨時間衰減至消失，這現象與一些物質在接近黑洞視界時繞著黑洞急促旋轉，放出的輻射因為重力紅移而衰減的情況相符。Several verifications are performed to examine the accuracy of the numerical model of the extended mild - slope equation at simulating wave refraction, diffraction and reflection on some representative topographies and good agreement has been achieved
針對多個典型地形按本文研製出的數學模式進行了波浪折射、繞射和反射的驗證計算，數學計算結果和理論解或實驗值吻合程度良好，說明本文的模式能很好地反映波浪的折射、繞射和反射現象。分享友人
