  1. The change of big pore section shape has more influence on soil water movement, but in small pore channels, the influence is small, in addition of pore section shape, it can get better prediction of unsaturated hydraulic conductivity

    粗大孔隙通道的截面形狀及變化對水分運動影響較大，較細空隙通道截面的形狀對水分運動影響較小。修正孔隙截面形狀對水分運動的影響，進一步考慮孔隙截面形狀因子對土壤水分運動的影響，可以得到對土壤水分運動參數更正確地預測。
  2.

    首先闡述了排矸石對環境產生的危害，其次對大巴溝隧道排矸石的物理力學性質進行了試驗研究，獲得了排矸石的物理力學性能指標。將排矸石粉碎后，作為粗骨料配製成混凝土，與目前阜新建築市場上所用的松山石子進行比較，證明其具有推廣應用價值。在此基礎上，利用均勻設計法，將排矸石作為粗骨料配製成高強混凝土，鋼纖維高強混凝土，聚合物水泥混凝土，瀝青混凝土，通過試驗測定其力學指標，獲得了各種排矸石混凝土的優化方程和最佳配合比。
  3. With the favor of these techniques, the static pressure distribution along the length and the velocity profile at the mini - channel exit were obtained. with the data of more than 500 flow states based on 13 kinds of mini straight rectangular channels that their heights were 0. 5mm and 1. 0mm, the effects of characteristic scale, surface roughness and the aspect ratio of rectangular on the characteristics of flow resistance of mini straight channels were studied

    採用在沿程測量氣流靜壓分佈、在出口測量速度分佈的方法，對高度0 . 5mm和1 . 0mm的13個微小直矩形通道的500多個狀態流場進行了測量，研究了特徵尺度、表面粗糙度、橫截面寬高比等因素對微小等直通道流動阻力特性的影響。
  4. The problem of signal processing for direct - sequence code - division - multiple - access ( ds - cdma ) signal over multipath frequency - selective mobile channels is considered. a new blind receiver is proposed. without the knowledge of the multiple - access interference users spreading code and the channel characteristics, the receiver achieves blind detection with prior knowledge of only the desired users spreading code and approximate timing. by using reduced rank adaptive decorrelating filter and adaptive multipath combiner which is based on decision - directed algorithm, the receiver gets the ability to combat both fading and the near - far effect at low cost. simulation results demonstrate that the proposed receiver offers high performance

    本文研究多徑頻率選擇性衰落通道下直接序列擴頻碼分多址（ ds - cdma ）信號的處理問題，提出了一種新型的盲接收機.該接收機不需預知多址干擾用戶的擴頻碼，不需預知通道參數，只需已知期望用戶的擴頻碼和粗略的定時，就可以完成用戶的盲檢測.同時，該接收機通過降維自適應去相關濾波和基於判決指導的自適應多徑合併，來獲得低成本和良好的抗衰落、抗遠近效應性能.模擬結果驗證了本文提出的接收機的優良性能
