貝它系數
英文
beta coefficient-
Of course, it optimizes so that it only copies data when a file changes, but the model is still based on having a complete filesystem tree for every revision
當然，它經過優化從而僅當文件改變時才拷貝數據，但是其模型仍然是基於對每個版本擁有完整的文件系統樹。In the dissertation, the study on carbon fiber reinforced concrete ( cfrc ) and plain concrete has been reviewed. then mechano - electric effect of cfrc and plain concrete, its mechanisms, the interaction among mechano - electric effect, piezoresistivity and seebeck effect, the electrical circuit model of concrete based on mechano - electric effect, electromagnetic emission of concrete, the mathematical model of mechano - electric effect are investigated. also the converse effect of mechano - electric effect of cfrc and plain concrete, that is, electromechanical effect, and the interaction between electromechanical effect and electrothermal effect of cfrc are examined
本文對碳纖維混凝土和素混凝土機敏性的國內外研究現狀進行了全面的評述，在大量實驗分析的基礎上，系統地研究了碳纖維混凝土和素混凝土的力電機敏性，研究了力電效應機理、力電效應與其它效應（壓阻效應、塞貝克效應等）的耦合關系、基於力電效應的混凝土電學模型、混凝土電磁發射現象、混凝土力電效應的數學模型等；論文同時對混凝土和素混凝土的電力效應、碳纖維混凝土電力效應與電熱效應的耦合關系等進行了探討；最後開展了基於力電效應的機敏混凝土結構應用研究。Bn is network structure with clarity semantics. lt exploits the structure of the domain to allow a compact representation of complex joint probability distribution. its sound probabilistic semantics, explicit encoding of relevance relationships, inference algorithms and learning algorithms that are fairly efficient and effective in pratice, and decision - making mechanism of facility, have led bn to enter the artificial intelligence ( ai ) mainstream. for the reasons that they have produced more and more practical values and economic profits in many important application fields, such as modern expert systems, diagnosis engines, decision support systems, and data mining systems, researchers from both industry and academia are thus taking them much seriously
它具有清晰語義的網路結構；它揭示領域對象的內在結構，是復雜全概率分佈的緊湊表示方式；其堅實的理論基礎、知識結構的自然表述方式、靈活的推理能力、方便的決策機制及有效的學習能力使其成為一種主要的不確定知識的處理方法。貝葉斯網路已經在專家系統、決策支持系統、數據挖掘系統和範例推理系統等許多重要領域產生應用價值和經濟效益。They provide tested and consistent numerical methods and the class hierarchy represents the wide variety of bayesien filtering algorithms and system models
它們提供了測試過的一致性的數字方法，用類層次化的方式表示多種貝葉斯過濾演算法和系統模型。To assess risk level, check these three factors : the fund ' s biggest quarterly loss, which will help you brace for the worst ; its beta, which measures a fund ' s volatility against the s & p 500 ; and the standard deviation, which shows how much a fund bounces around its average returns
關于如何判斷風險水平，請參照以下三個要素:基金每季度的最大損失，這能幫助你做好最壞的打算;貝塔系數，它能反映基金相對標準普爾指數的波動程度;標準差，這能夠顯示一個基金圍繞其平均收益上下搖擺的幅度。分享友人
