We survey external methodology papers about long - run event studies, and focus on analyzing and introducing " the choices of expected return models ( or return benchmark ) ", " the approaches to measure abnoumal performance ", and " the empirical power and specification of test statistics "
摘要本文對國外長期事件研究方法論文獻進行了全面的梳理，並著重介紹和分析了期望收益模型（或收益基準）選擇、異常收益度量，以及檢驗統計量的設定與檢驗力等。 -
As one of modern design methods, long - distance online calculation is a method which can be easy to fulfil sharing the resouce of design. here penman compiled a suit of software providing the service of structure analysis and optimize for the water processing equipment by www server. it ' s platform to develop and run is microsoft windows 2000 server with iis 5. 0. the technology is based on microsoft asp, and the programming language is vbscript. then, there is a contrast calculation test between this suit of software and ansys 6. 0 for the representative structure of the 3 kind of beam. the intent is to evaluate the suit of software. the result indicates : its correctness of calculation result is better ; only for the amount of the element is too few, the calculation result is relatively large. so this is a safe scheme
筆者以windows2000server和iis5 . 0為開發和運行平臺，基於microsoft的asp技術，使用vbscript語言編寫了一套可通過ww服務器提供水處理設備遠程結構分析和優化服務的軟體。並且針對3種梁的典型結構進行了與ansys6刀的計算結果對比測試，對這套軟體進行了評估。測試結果表明：這套軟體在計算結果的正確性方面表現較好，只是由於單元數目較少，導致計算結果偏大，但是這是屬于比較安全的方案。 -
We research the stability of the three - factor model by using chow test and research the coefficient stationary by using unit root test, and forecast the coefficient of the model using arma 、 garch model. the results show that the model is instability in the long run, most coefficient is non - stationary, and we can preferably forecast the coefficient by using the arma 、 garch model. in the process of designing strategic investment portfolios and the strategic risk budgeting prevailing in resently which in order to control investment risk, the investors generally structure their portfolios in different industries
模型回歸系數是測度投資對象系統風險的重要指標，我們利用chow檢驗對證券收益三因素模型結構的穩定性進行了分析研究，用adf檢驗對模型的三個回歸系數的穩定性進行了實證分析，採用arma和garch模型對回歸系數的預測能力進行了研究，結果表明組合三因素模型結構不穩定，但短期比長期結構穩定性要高;大部分組合回歸系數時序穩定性較差，同時arma和garch模型對每個回歸系數時間序列進行預測顯示有較好的預測能力。 -
It is researched that the influence on the tube lifetime of the metallographic structure and the alloy element and the rigidity by the test the superheater and reheater tube which is made of 12cr2mowvtib steel. the metallographic change after the tube has run in the high temperature and high pressure condition for long time is more believable and frank than the intensity lifetime analysis to evaluate the tubes remain lift time
然後，通過試驗研究了過熱器和再熱器管12cr2mowvtib鋼材的金相組織、合金元素和硬度等對管道壽命的影響，分析管材在高溫高壓下長期運行后金相組織的變化情況，對管材定性壽命評估，這種與強度壽命分析完全不同的方法直觀可信的展示了材料損傷狀況。 -
Aimed at the short time run of the generator, multi - channel and high precision in aircraft test on ground, based on the idea of multi - channel long time record at locale, then playback and analysis, an aircraft electric multi - channel test system based on vxibus is designed, it is proved to have convenience and high test - precision, and well fulfills the need of multicenter test at locale and implements that multilcenter data can be playback and analysed
摘要針對目前飛機地面電氣測試中發電機開機時間短、測試通道多、並且要求測試精度高的要求，按照現場長時間多通道記錄，後期回放處理的設計思路，設計了一種基於vxi總線技術的飛機電氣多通道測試系統，實踐證明該系統使用靈活，測試精度高，很好滿足了現場實驗多通道數據同時測量的要求，並實現了對多個通道數據後期回放及分析處理。 -
It shows that there is cointegration relationship between the economic growth rate and the m1 increase rate. then by using the cointegration, granger causality method, impulse - response analysis, vector error correction model with markov regime switching to test the equilibrium relationship in long run and the short fluctuation pattern in short run between the real output and m1 increase rate, it shows that monetary supply can affect the macroeconomic effectively, and the interest rate and stock market value can not affect the macroeconomic effectively
本文研究了經濟增長與貨幣供給量、利率、股票市場等貨幣中介指標的關系，得出經濟增長率與m1增長率具有協整關系的結論，在此基礎上使用協整分析、 granger因果關系檢驗、脈沖響應分析、具有markov區制轉移的向量誤差修正模型等最新的經濟計量方法，描述和檢驗了中國經濟周期波動過程中實際產出與貨幣供應量變動的長期均衡關系和短期波動模式。 -
On the basis of analyzing the result of the test, we have improved the structure of the damper and revised the systematic model. we have experiments on the damper to test its damping performance. comparing with the simulation force - displacement curves, we gave an explanation of why the factual force - displacement have aberrances, which gave warrants to the parameter design and structure ' s improvement. we found the state equation of the semi - active suspension on the semi - active adaptive control strategy and use computer simulations to compare the passive suspension structure and er semi - active suspension. computer simulations indicate that er semi - active suspension have greatly improved driving smoothing and control stability. at the same time semi - active suspension is of simple structure and low cost. so in the long run, the semi - active suspensions may have wider application
在對試驗結構進行分析的基礎上，改進了減振器的結構，修正了系統的模型；對自適應減振器性能進行了大量的測試，通過與模擬結果比較，分析了造成示功曲線局部畸變的原因，為機構及其參數設計以及改進提供了依據；基於振動半主動自適應控制策略，建立了半主動懸架系統的狀態方程，並且進行了模擬，從而得出與被動懸架結構相比，採用電流變流體減振器的半主動懸架在汽車行駛平順性和操縱穩定性上均有較大的改善，性能大為提高。
