  • density : n. 1. 稠密；濃厚。2. 【物理學】濃度；密度；比重。3. 愚鈍，昏庸。
  1. When designed, the high - speed generator with a permanent magnet ( pm ) rotor is preferred because of its simple structure, without excitation high energy density of the pm material

    永磁轉子式高速發電機由於具有結構簡單、不需勵磁、效率高和能量密度大等優點成為高速發電機設計時的首選。
  2. The result shows that argon gas can not only promote the excitation of plasma at low pressure, but also improve discharge state, increase the density and activation of reaction radical and improve the quality of diamond films. on the other side, argon can cool the plasma and maintain low temperature of substrate due to its big ionization section and high collision probability with gas molecules

    結果表明，氣體系統中引入氬氣一方面不僅有利於維持低壓放電，而且改善放電狀態，提高反應活性基濃度和活性，提高低溫沉積金剛石膜的質量；另一方面，由於其大的電離截面使其和電子碰撞的幾率大大提高，對等離子體進行冷卻，有利於基片溫度的降低。
  3. Using the multi - cloud model to fit the ha - spectra data of the april 27, 1981 post flare loop, we obtained the spacial distributions of the four physical parameters in the space of the post flare loop : the line - of - sight velocity v the excitation temperature tex, the micro - turbulence velocity vt and the column number density of the hydrogen atoms at the second level along the line - of - sight direction fields n2

    我們利用多雲模型處理了1981年4月27日太陽西邊緣耀斑后環的三個時段的h光譜掃描資料。通過對1000餘條對稱譜線和不對稱譜線的計算，我們得到了該耀斑后環各個時段在空間上的視向速度場，激發溫度場，視向上處于第二能態的氫原子柱密度場以及湍流速度場。
  4. The random excitation of the four wheels is used as the input of this system. the changing rule of vertical displacement, three directions of acceleration power spectrum density function of person - chair system of model ca - 141 and etc. in the frequency domain is simulated using matlab. the rationality of the model is analyzed and validated by comparing of relevant testing results and theoretic analysis

    以頻域內四輪隨機激勵作為系統輸入，用matlab模擬低地板城市客車等三種車型人椅系統三向加速度功率譜的變化規律，逐項分析車速、懸架剛度與阻尼參數變化對車輛平順性的影響，通過與相關研究結果的比較及理論分析驗證了模型的合理性。
  5. In the high frequency c - v experiments, the large flat - band shift in sio2 / p - sic indicated that there was high density of deep interface states. the deep interface states were simply studied by using photo excitation

    在無光照條件下，比較了n型和p型sicmos的不同特點，對其深耗盡特徵和p型sicmos的平帶電壓作了討論和解釋。
  6. The characteristic of excitation of the acoustic field is investigated for sources with various frequencies. the effects of an isotropic medium, inclined formation of different azimuth, horizontal or vertical fracture and its width or density on the propagation of the acoustic field are investigated. the fluid in borehole is also investigated

    研究了聲源在不同頻率下的聲場激發特性，考察了井外介質為均勻介質、存在不同傾角的地層界面、存在水平和垂直裂縫以及裂縫寬度和密度等對井內外聲場傳播的影響以及井眼流體對井孔聲場的影響。
