  1. Crack propagation characteristics of x70 pipeline steel under fluctuation loading

    70管線鋼裂紋擴展特性研究
  2. It is found, in one - dimensional subsurface flows, that porosity and storativity play an important role in the propagation of the head potential fluctuation

    由研究發現，一維地下水層中，受擾動地下水水頭的傳遞快慢受飽和土壤儲水系數及有效孔隙率的影響。
  3. Study on characteristics of fluctuation for optical wave propagation in the atmospheric turbulence

    湍流大氣中的光波閃爍研究
  4. According to the theory of optical wave propagation in the slant path and the itu - r turbulence structure constant model, which is altitude dependent and proposed in 2001, the modified rytov method is extended to be applied to study on the problems, which waves propagate in the slant path. the scintillation index as a function of the rytov variance is obtained from weak to strong fluctuation regions with plane wave and sphere wave incidence, respectively

    根據斜程傳輸理論和2001年提出的itu - r湍流大氣結構常數模型，將修正pytov方法推廣應用於斜程傳輸問題研究，得到了平面波和球面波斜程傳輸時的閃爍指數，分析了湍流內尺度、近地面風速等參量對閃爍指數的影響。
  5. Angle - of - arrival fluctuation of light beam propagation in strong turbulence regime

    光束在強湍流區中傳播的到達角起伏
  6. Since the effects of turbulent atmosphere is prominent, this thesis concentrates on the effects of the turbulent atmosphere on the laser beam propagation in the atmosphere. the atmosphere refractive index model, especially refractive index fluctuation, power spectrum, phase spatial structure constant are introduced in the following and the specific structure function is achieved

    根據大氣折射率模型，以及折射率起伏功率譜密度和相位空間結構常數，得到具體的結構函數；通過長程情況下的馬爾科夫近似，得到了互相關函數，對數振幅和相位協方差函數。
