  1. In order to utilize the frquency resource adequately and increase the capacity of mobile communication system, the wireless electric wave propagation of existing mobile system always adopts the microcell structure. forecasting the path loss characteristic of electric wave accurately can provide the necessary condition for the layout and design of wireless network, at the same time it is a precondition for the research on the microcell mobile system. the methods of forecasting of wireless electric wave propagation can divide into two parts : one is pluse and respond, that is establish the empirical model based on experimental and statistical data ; the other is ray tracing method, that is establish the deterministic model based on theoretical analyse. the paper discuss the characteristic of wireless signal electric wave transmition in symmetrical atmosphere of earth, and introduce the common path loss transmition model in land mobile communication system, also point out the localization of these models based on experiential methods

    而精確預測線電波傳播路徑損耗特,則為合理的微蜂窩線網路規劃、設計提供了必要條件,同時也是研究微蜂窩移動通信系統能的前提。線電波傳播預測的方法分為兩類:一是用沖激響應法,即根據實驗、統計所得數據建立經驗傳播預測模型;另一種是用射線跟蹤方法,即依據理論分析來建立確定的傳播預測模型。本文首先討論了在地球表均勻大氣線電波傳播的基本特,介紹了陸地移動通信系統常用的幾種電波傳播路徑損耗經驗預測模型,並指出了這些經驗傳播模型對于微蜂窩線電波傳播特研究的局
  2. Accordingly ray tracing model for microcells propagation prediction has become an important subject. this paper discussed the characteristic of propagation in symmetrical atmosphere on the earth, and introduced several kinds of traditional path loss propagation model in land mobile communication system, also pointed out the localization of these models based on experiential methods

  3. A bearing surface transmits the interaction between an arch dam and its foundation, the strength of which directly affects the constraint of the bedrock to the dam, and thus affects the stress and deformation of the dam. the influence is studied in this paper with nonlinear finite element method, as an example, for a high arch dam in design. the results show that the influence on stress is only limited within the local area near the bearing surface, larger on the maximum principal tensile stress than on the principal compression stress, and the decrease of the strength does not cause unlimited increase of the maximum stress. the influence on the displacement of the top of the dam is smaller than that of the bottom of the dam, especially the relative downstream displacement. at the lower strength of the bearing surface, the relative downstream displacement at the bottom of the dam increases with the decrease of the strength

    建基是傳遞拱壩和基巖相互作用的紐帶,它的強度直接影響基巖對壩體的約束,從而影響壩體的應力和變形.採用非線單元法,以設計的某高拱壩為例,分析建基強度對壩體應力和變形的影響.結果表明建基強度對壩體應力的影響僅於建基附近的局部范圍,對最大主拉應力的影響要大於對最大主壓應力的影響,建基強度的降低不會地增大壩體的應力數值;建基強度對壩頂位移的影響較,但對壩底位移(尤其是順河向相對位移)的影響較大,當建基強度較低時,壩底順河向相對位移隨建基強度的降低而增大
  4. After 1989, the increase of demand slowed down and facing the complexion of low degree of industrial concentration of product market and financial strain of medi um and small - sized enterprises caused by the circulating trap of " credit squeeze - - - bad loan ", the advantageous enterprises " " wallow in money ", specifically, those listed companies that could finance from the stock market, began to take predatory pricing strategy in succession and tried to enlarge market share and obtain high return by squeezing medium and small - sized enterprises out of the market after 1998, the vicious circle of deflation and " credit grudging " of banks in product and credit markets, overcapacity, the difficulty of retreating of loss - incurring enterprises in some industries from the market for institutional reasons and over - competition in some industries, led to the incessant decrease of enterprises " global income, persistent increase of rate of debts and constant rise of ratio of bad assets of banks, which further intensified the vicious circle of deflation and " credit grudging " of banks

    如在改革開放初期,在產品市場需求旺盛和信貸市場預算軟約束的情況下,各類企業的最優決策就是採用高負債、高擴張的「負債的有責任效應」策略來搶占市場並獲得高回報; 1989年以後,需求增速開始放緩,臨產品市場產業集度較低和信貸市場「信貸緊縮-不良貸款」循環陷阱導致的企業資金緊張的局, 「錢袋鼓鼓」的優勢企業(尤其是那些可以通過股票市場融通資金的上市公司)紛紛採用掠奪定價策略,試圖通過把企業擠出市場來擴大市場份額並獲得高收益; 1998年以後,產品市場和信貸市場形成了通貨緊縮和銀行「惜貸」惡循環的狀況。產品市場上部分行業生產能力嚴重過剩,且由於體制等原因導致虧損企業法退出,因此這些行業出現了過度競爭的現象,企業總體收益的不斷下滑、負債率不斷提高以及銀行不良資產率的持續上升,又進一步加強了通貨緊縮和銀行「惜貸」的惡循環。
  5. At present, limit equilibrium method is one of the conventional slope stability analysis methods. it ca n ' t consider nonuniformity of mechanical characteristic of landslide body and its rock bed and the effect of stress distribution on the gilding surfaces, since the rigid body assumption is adopted in this method. furthermore, this method ca n ' t accurately consider inactive forces between slices

    目前常用的邊坡穩定分析方法的極平衡法由於採用了剛體假定,法考慮塌滑體及其基巖力學特的不均勻和滑動上應力分佈的影響,此外還不能準確考慮條塊間的作用力,而另一種常用的邊坡穩定分析方法? ?常規有元分析方法,當滑動全部處于屈服狀態或邊坡的實際抗滑穩定安全系數於1時法求解。
  6. The paper is composed of five chapters the first chapter first introduces the concept, characteristics and the course of development of the stock index futures, then deduces the pricing formula of stock index futures and further analyses the functions of stock index futures and the impact of its transaction on the fluctuation of the spot transactions. the second chapter demonstrates the need and feasibility of the introduction of the stock index futures in china. through the empirical analysis of the market risk of china ' s stock market, we can see that the risk difference between individual stocks, so a portfolio investment wo n ' t help much in risk aversion

    本論文共分為五章,第一章在介紹股票指數期貨的概念、特點以及產生與發展的過程的基礎上,對股票指數期貨的定價公式進行了推導,從而引出股票指數期貨的套期保值、指數套利、資產配置、組合保險等作用,進而分析股票指數期貨交易對股票現貨市場波動的影響;第二章主要是對國推出股票指數期貨的必要和可行進行論證,通過對國股票市場風險測度的實證分析,得出了國股票價格波動齊漲齊落,個股之間的風險差異的特點,因此,投資者進行投資組合的避險效果就很有論是個人投資者還是機構投資者,都必須國股票市場巨大風險的事實。
