Thirdly , this study makes overall analysis about securities market investments , resolves cognitions about investment rules , creates three principles about securities market cognitions : one , the absolute rules on securities market do not exist , which must be associated with special space - time factors . two , all struggles for study market authenticity and continuity with natural scientific pattern will end with failure 第三,本文對投資活動進行全方位的系統論述,深入剖析了投資規律本性認識的問題,獨創了證券市場認知“三大定律” :其一,證券市場不存在人們所謂的絕對規律性,其研究必須考慮具體的時空因素。

The air - defense troop especially the ground - to - air troop must fight in its position , and the correct disposition and position choice of the ground - to - air missile troop or not is an important factor that the battle to anti - shot the air - attack validity or not , the disposition and position choice of the ground - to - air missile troop need to cinsider some terms synthetically such as geography , mobilization and fighting - time factors ect 摘要防空部隊特別是地空導彈部隊抗擊敵空襲作戰必須依托相應的陣地進行,而地空導彈部隊陣地部署與選擇的正確與否是地空導彈部隊能否有效進行抗擊敵空襲作戰的一個重要因素,地空導彈部隊陣地部署與選擇需要綜合考慮地形條件、機動條件、作戰時間條件等各種因素。

On the basis of research on market efficiency , index funding , clustering algorithm and time factor , 295 stocks in shenzhen stock market are selected as the research objects . clustering algorithm with time factor is applied to choose portfolio population , and then single index model is used to calculate the weight of every individual stock in order to construct an index proxy portfolio to track shenzhen composite index 本文在對市場有效性、指數化投資、聚類算法和時間因子等有關理論進行分析研究的基礎上,以在深圳證券交易所上市的295只股票為研究對象,使用加入時間因子的聚類算法選擇證券投資群體,再利用單指數法構造市場指數代理證券組合,以此來逼近深圳綜合指數。

The liveness and boundedness are the most important properties of petri nets . these properties of classical petri nets mostly have had satisfying judging criteria , but the corresponding properties of petri nets with time factors are seldom studied , and a lot of literatures are focusing on concrete applications 活性和有界性是petri網中最重要的性質,對于傳統petri網中的這些性質,大都已經得到了較為滿意的判定結果,而對含時間因素的petri網的這些相應性質研究得很少,大部分文獻都是側重于具體的應用。

The affect of transaction costs on the benefits of stakeholders are accepted within the range of 10 . 00 % - 50 . 00 % . at present , public finance is used as compensation way to environmental benefits of forest resources , but from the long - term view , market creation of environmental benefits of forest resources is a better solution , government agencies will play important roles in institutional arrangements of environmental benefits of forest resources . outstanding of the paper are the following : firstly , time factor has been included in faustmann forest resource model ; secondly , more data are used to estimate tree growth models ; thirdly , time series models of environmental benefits of watershed forest resources are estimated to show time changes of environmental benefits of forest resources ; finally , transaction costs are included with regard to compensation fee institutional arrangements 分析結果表明:水源涵養林的環境效益顯著,與傳統的僅考慮木材效益的林業經營方式相比,考慮環境效益后將使林業生產實踐和社會福利發生變化;對水源涵養林環境效益給予小幅度的補償如2 . 00 10 . 00即能達到改善環境、提高經營者收益和社會福利的目標,補償水平提高到一定程度以后其作用效果減弱,在經濟水平較低的階段或地區可以選擇較低的補償標準,當經濟水平發展到較高程度以后,可以適當提高補償標準,逐步過渡到完全補償;考慮交易成本以后,使利益相關者的福利有所減少,交易成本幅度在補償標準的10 . 00 50 . 00的范圍內時影響相對較小;目前適合于采用公共支付體系的經濟補償方式,但從長遠來看,創建水源涵養林環境服務市場是一種比較好的補償方式,且政府在水源涵養林環境服務市場制度安排方面仍將發揮重要作用。

The methodologies include a series of methods consisting of data collection scenario , data disposal , choosing the appropriate model , model calibration , determining the road weigh , and etc . , which are feasible under the infrastructure and technical conditions in the current stage in china , and the real - time factors are also considered 這是一種在現階段基礎設施和技術條件下切實可行的、并且考慮到實時因素的標定以出行時間度量的道路權重的方法體系,包括數據采集方案、數據處理、選定現有模型、標定模型、確定道路權重的一系列方法。

The mathematics model of newsboy problem with time - based parameter is given , and through analyzing model and numerical instance , it shows , with contrast of traditional newsboy problem that time factor is not taken into account , the former can increase the income of the dealer 建立了正態分布下時變參數的報童問題的數學模型,通過模型的求解和數值分析,結果顯示,與傳統的不考慮時間因素的報童模型相比,前者能夠增加零售商的收益。
