在網路會計時代，會計實務正在發生著顯著的變化：生產及組織的日趨國際化，虛擬化；新知識新技術帶來的挑戰引發經營風險的加劇， 「虛擬」企業的可能轉瞬即逝；信息傳遞的即時化，人們對實時信息的要求日益迫切；非貨幣信息，非定量信息在一個企業尤其是高科技企業中的比重逐日增加。This paper establishes the linear model of hydro - turbine and deducts its transfer coefficients. then the optimized operation parameters are gained in the frequency disturbance and load rejection simulation. through comparing dynamically, this paper analyses the impact on its dynamic performance if some governing system parameter changes
在研究小波動情形時，即系統在穩定工作工況點附近小瞬變時，可以把非線性系統進行線性化處理;本文建立了水輪機調節系統的線性化模型，推導了其中的傳遞系數;對水輪機調節系統的頻率擾動和機組突甩負荷工況進行了模擬試驗，整定了最佳調節參數;通過動態比較，分析了調節系統參數改變對其動態性能的影響。With the rapid development of world economy and the tough change of market competition, enterprises require more and more fast and safe delivery of business documents and samples, in the meantime, costumers are seeking for shopping without leaving houses. above two aspects engender a new service means - express service, to meet the bloom demand of market, which is with the character of fast speed and door - door
隨著全球經濟的快速發展，市場競爭瞬息萬變，企業在商業活動中越來越追求商業文件、樣品及高精物品的快速、安全的到達；消費者則追求足不出產便能購買到所需的日常用品，市場的旺盛需求使傳統的貨物運輸服務產生了一種具有快速、門到門兩個特點的服務方式? ?快遞服務。Firstly, wall ’ s transfer matrix is deduced by laplace transformation based on 3r2c thermal network model. secondly, frequency response of transfer matrix is calculated. thirdly, we make the frequency response of transfer matrix of stimulation model equate the theoretical frequency response of wall transient heat conduction by applying appropriate identification algorithm, from which we can obtain every polynomial ’ s coefficient of model transfer function, then each parameter of resistance and capacitance is calculated by appropriate optimization algorithm
首先，根據模擬熱流網路模型用拉普拉斯變換推出墻體的傳遞矩陣;然後，計算傳遞矩陣的頻率響應;最後，採用頻域回歸方法求出模型傳遞函數各次項的系數，進而通過一定的優化演算法確定模型的各個熱阻、熱容參數，使通過模型建立的多項式s -傳遞函數與墻體瞬時傳熱的理論超越s -傳遞函數完全等價。According to the analytic results of transient heat conduction in semi - finite object, the macroscopic physical behavior on heat flux and temperature variation were investigated
根據半無限大物體的瞬態熱傳導問題的解析結果，對瞬態熱傳導過程中熱流傳遞與溫度變化的宏觀物理行為進行了研究。In this work, incident super - gaussian pulse propagation in conventional single - mode fibers has been investigated in detail after taking into account the fiber chromatic dispersion. the results show that for an incident super - gaussian pulse with steep leading and trailing edges, its shape undergoes a variation from near - rectangular, two - peak, and finally to single - peak. in the meantime, its peak intensity increases at first, after passing a maximum, and finally decreases monotonously
數值模擬的結果表明:超高斯入射光脈沖在光纖中傳輸時脈沖波形、瞬時惆啾、以及峰值強度的演變規律與高斯入射脈沖不同，脈沖波形不再總保持單峰結構，通常將經歷一個從近平頂、多峰、最後到單峰的演變過程;從脈沖的前沿到后沿，瞬時明啾也不再為線性，而是具有多個極值;峰值強度隨傳輸距離的變化趨勢也不再為一單調遞減，而是先增加后減小。For reducing the risk, the owners of goods, request the small batch, many species, and quick supply in the logistic, to adapt to the volatile market. thus it has been the common need of the service and the owner that speeding the single certificate delivers and disposals
貨主為了減少風險，要求小批量、多品種、供貨快的物流服務，以適應瞬息萬變的市場，因此提高單證傳遞速度和處理速度成了貨代和貨主的共同需求。分享友人
