Under this circumstance, our treasury bond market exits lots of shortfalls which impede further development for this market. in this essay, combining with the experience in developing country " s experience, it analyses some challenges which confronted chinese bond market, such as liquidity in the interbank market has yet to be improved, duration in bond products are yet to be rational, a sound yield curve is yet to be take shape, the separation between exchange and interbank yet to be broken. in order to solving above issues, this essay suggests that it should develop market maker system to increase market liquidity ; manage balanced treasury bond ; issue short and long term treasury bond in proportion to improve duration and yield curve ; develop bond derivative products such as future trading, open style repurchasement, so it can provides tools for risk protection
但隨著我國經濟的快速發展，金融市場已今非昔比，中國成為了世貿組織的成員，中國資本市場要走向國際化，利率的市場化是大勢所趨，在此前提下，我國國債市場還存在著很多不足，越來越阻礙著國債市場的進一步發展，本文結合世界發達國家的先進經驗，剖析了我國國債市場存在的一些問題如：流動性有待改善、國債期限結構不合理、無法形成科學合理的益率曲線、交易所市場與銀行間市場割裂等，為解決這些問題，本文建議應發展做市商制度以提高市場流動性；實施國債余額管理，發行短期國債及長期國債，改善國債期限結構，以形成科學合理的收益率曲線；發展債券衍生金融創新工具如國債期貨交易、開放式回購等，為投資者提供避險工具等等。 -

Based on the theory of stochastic finite element, the structural parameters of frame - shear structure including stiffness and mass and damping are simulated to be stochastic variables. by solving recurrence equation of stochastic finite element, the duration curve of mean value and standard deviation of seismic response can be obtained for every floor of frame - shear structure. an analysis is thus given to the effects of independent variation and simultaneous variation of structural parameters on the seismic dynamic response of frame - shear structure. as shown by the results, with regard to frame - shear structure, the effect of variation of strucural parameters on the change of mean value are chiefly the increase of standard deviation of response. variation of stiffness will cause the response of frame - shear structure to variate greatly ; variation of mass shows less effect ; and variation of damping shows insignificant effect. the effects of simultaneous variation of various structral parametres on seismic response are only slightly greater than the effect of stiffness variation alone
以隨機有限元理論為基礎，將框剪結構的剛度、質量、阻尼等結構參數為隨機變量.通過求解隨機有限元的遞推方程，得到框剪結構各層的地震動力響應均值和標準差歷時曲線.分析結構參數單獨變異，以及同時變異對框剪結構地震響應的影響.研究結果表明，對框剪結構而言，結構參數的變異對響應的均值變化影響都不大，主要是增大響應的標準差.剛度的變異性將引起框剪結構的響應發生大幅度變異，質量的變異性影響稍小，阻尼的變異性影響不顯著.結構各參數的同時變異，對框剪結構地震響應的影響，僅比剛度單獨變異的影響稍大 -
