  1. At the same time, the quality of different - state water was studied. the results show : the soil bulk density of the fir wildwood heightens with the increase of soil depth, specifically 0. 74 > 0. 94 andl. 34g / cm3, the saturated, canaliculus and field moisture contents decrease gradually in layer a, b and c, accordingly the soil total foveola decreases gradually, and the moisture - hold capacity of the soil lessens gradually with the increase of the soil depth ; there is small difference of the soil bulk density between layer a and b in the outer space, which are respectively 0. 92 and 0. 99g / cm3, and the other laws are the same as the in ner in the main ; reverse success often occurs in the low position of the thoroughly - fell trace and plateau marsh is formed

    結果表明：冷杉原始森林土壤容重隨土層深度的增加而增大，分別為0 . 74 、 0 . 94 、 1 . 34g cm ~ 3 ，飽和持水量、毛管持水量、田間持水量a層、 b層、 c層逐漸減小，十壤總孔隙度也逐漸減小，土壤的持水能力隨深度的增加逐漸減弱；林外空地a層、 b層十壤容重相差不人，分別為0 . 92和0 . 99g cm ~ 3 ，其它規律與林內人體相同：皆伐跡地的低洼地段容易發生逆行演替，形成高原沼澤地。
  2. In order to otain high quality zno thin films, we, for the first time, employ the plasma enhanced chemical vapor deposition ( pecvd ) to prepare high quality zno thin film at low temperature using a zinc organic source ( zn ( c2h5 ) 2 ) and carbon dioxide ( co2 ) gas mixtures. the effects of the growing condiction and the native oxide layer of si substrate on the quality of zno thin films was studied in detail. to prepare p - zno and overcome the dufficulty of reverse due to the interaction between the n atomic, we obtain high qulaity p - zno by a easy way of thermal zn3n2

    為了在低溫下制備高質量的氧化鋅薄膜，我們採用金屬有機源和二氧化碳氣源，首次利用等離子體增強化學氣相沉積的技術在低溫下制備了高質量的氧化鋅薄膜，系統地研究了生長條件以及襯底表面氧化層對薄膜質量的影響，確定了生長高質量氧化鋅薄膜的優化條件；為獲得p - zno材料，克服在zno中摻n雜質間相互作用影響摻雜效率不易獲得p - zno的困難，我們通過熱氧化zn3n2的方法制備了p - zno ，獲得了一系列研究結果： 1 、詳細研究了氣體流速比，襯底溫度和射頻功率實驗參數對氧化鋅薄膜特性的影響。
  3. Because of the complication of ground condition, the ground is regarded as continuous layers and each layer of soil is defined as a uniform and elastic object. by solving the wave equation ( navier equation ) of three - dimensional elastic object, the results of ground under moving loads in wave number ? frequency field are obtained, then through the rapid fourier reverse transform, the results in space - time field are obtained

    由於地質條件的復雜性，將地基看成是層狀的，並且每層都是均勻彈性的，通過解三維彈性體的波動方程（ navier方程）得到地基在移動荷載作用下的波數-頻域的解，再通過快速fourier逆變換（ fft ）求得空間-時間域的解。
