    本文採用室內正交實驗，利用自製的常水頭滲透儀，研究了礫石含量、孔隙比和顆粒形狀3個因素在不同水平下對土石混合體滲透系數的影響。
  2. Then, we establish the finite element analysis models of the antenna in different structure layout, and obtain the corresponding frequencies and model shapes. finally, according to the importance of each object, we set up the model of multiple objects that aims to maximize the first natural frequency and minimize the mass. combining orthogonal experiment and variant weighting coefficient method, we formed an effective multiple objects optimized algorithm basing on the neural network and genetic algorithm

    本文首先詳細的敘述了天線結構的各組成單元，闡明了天線反射拋物面的形成原理；然後在ansys軟體環境中建立了不同結構布局下天線的有限元分析模型，分析計算了各種情況下天線的的固有頻率與振型；最後依據天線各指標的重要性，建立了以一階固有頻率最大、質量最小為目標的天線結構多目標優化設計模型，並基於神經網路和遺傳演算法，結合正交實驗和變加權系數技術，形成了一種有效的多目標優化演算法，在matlab平臺下實現了天線的結構多目標優化設計計算程序，求得了天線的最佳結構參數。
  3. A important result is the one - orde r expression of ar ( p ) yt = dyt - 1 + e, from paralleling a high - order differential equation transformation into a one - order differential equation system, the one - order expression exposes that the ar ( p ) is only a certain more - multivariable power series process and, if a process is described as an ar ( p ), the sufficient and necessary condition is the spectrum norm a of the coefficient matrix d less than one. simplification of ar ( p ) not only brings about orthogonal f ( h ) but also provides global foretelling formula

    作者用高階微分方程化一階微分方程組的方法，獲得多元弱平穩序列p階自回歸模型的一步滑動平均表達式，證明了ar （ p ）的是一個更高維的冪級數的線性過程，從而，說明了ar （ p ）關于序列依概率成立的充要條件是：該模型更高維的冪級數的線性過程的表達式中系數矩陣d的譜范數1 。
  4. Based on the previous and through the uniaxial tension damage experiment and comparing to the uniaxial compression damage experiment, the paper makes research on the anisotropism of the damage and the difference of the damage between the uniaxial tension and the uniaxial compression, combining with orthogonal anistropic damage model and exponent function damage developing equation. through the formulae deduction, the damages caused by the same absolute value tension and compression strain have the comparing character in some extent and corresponding decay coefficient

    本文在前人研究的基礎上，通過單軸拉伸損傷試驗，及其與單軸壓縮損傷試驗的比較，進一步結合正交異性損傷模型與指數函數損傷演變方程，對混凝土體中損傷的各向異性以及單軸拉伸和單軸壓縮情況下損傷的差異性進行了研究探討，經過公式推導，提出絕對值相等的拉、壓應變產生的損傷具有一定的可比性，並給出了進行可比性換算的折減系數。
  5. By orthogonal tests, the influence of three factors on the coefficient of permeability of soil - rock - mixture, the significance of different factors was determined
