  1. Electric knudsen number

    電氣克努森數
  2. Knudsen inverse number

    克努曾逆數
  3. 4. the paper proved that when the cooling channel belongs to the transitional region from macro - scale to micro - scale, whether the macro - scale theory or the micro - scale theory will be used depends on the accuracy that the researcher reqired, and does not need to depend on the knudsen number

    4 、當冷卻通道屬于宏觀尺度到微觀尺度的過渡區域時，求解計算是採用宏觀理論還是採用微觀尺度的理論，主要是看研究者對求解答案的精度要求，而不必一定按照kn數進行判斷。
  4. Magnetic knudsen number

    磁克努曾數
  5. Knudsen similarity number

    克努曾相似數
  6. The hot - dip - depth and temperature difference between fluid and platelet wall are influenced by many factors, such as the coefficient of heat conductivity of platelet and fluid, the coolant fluid, the knudsen number, and so on. high temperature make kn number become bigger, and then microscale effects become notable

    3 、熱浸深度、流體與層板壁面的溫差大小要受層板的導熱系數、冷卻劑流量及流動的kn數等因素的影響。高溫條件使kn數增大，微尺度效應增強;而高壓條件下kn數減小，微尺度效應減弱。
  7. Through comparison and analysis the result gained from micro - scale theory and macro - scale theory, we can drew several conclusions as follows : 1. as the knudsen number ( kn number ) is very small, the inaccuracy would be neglect, when the macro - scale theory is used to solve the problems which were proposed in the paper

    通過對微尺度理論和宏觀尺度理論研究結果的比較，可得以下幾條結論: 1 、由於knudsen數（ kn數）很小，用常規尺度理論求解本文所研究的微小通道內的流動阻力，其誤差可忽略不計。
