1 water threatening - resistant characteristic : for instance , the outside tangency wall of epidermis cell prominently thicken ; the outside of epidermis cell are obviously covered by cuticle ; few stomats exists ; stomats are sunken ; and it has stmatic chamber structure , big aqueous tissues - parenchyma cell , mucilage cell , abnormal vascular , and soon 抗水分脅迫的抗鹽結構特征。如表皮細胞外切向壁明顯加厚,表皮外有明顯的角質層覆蓋;氣孔稀少、氣孔下陷及具有孔下室結構;大型貯水組織薄壁細胞、粘液細胞、異型維管束等。

Basing on the two order tangency at initial point between isotropic curve and hugoniot curve , a new method for calculating cold energy cold pressure and cohesive energy for solid is presented in the paper , comparison with experimental data manifest that this method is very good and can be applied 利用在初始點等熵線和沖擊絕熱線二級相切的性質,給出了一種可用于計算固體冷能冷壓和結合能的新方法,并推導了利用hugoniot參數計算結合能的公式。與實驗數據的比較表明,這種方法是有效可行的。

With the diminishing marginal utility , the point of tangency may run to the area far to the central city . through the statistics and analysis , we find out that there are several characteristics in the central city tourism market : ( 1 ) the city tourists tour at weekends and gold weeks , and they want to buy such tourism products as “ safe , convenience , short range and cheap “ . ( 2 ) they tour by car or by themselves not go with tour team , ( 3 ) and stay out for zero to two nights 本文重點對中心城市居民出游市場進行了統計分析,通過分析發現中心城市出游市場總體表現出以下特點: ( 1 )城市居民外出旅游時間除黃金周以外,主要集中在周末,其時間約束型的旅游產品需求以“安、近、短、廉”為特征的旅游產品為主; ( 2 )出游方式以自駕車和自主安排為主,團隊游客的比例在逐步下降; ( 3 )出游逗留時間以在外逗留0 ? 2夜為主; ( 4 )城市居民出游人群中女性比例高于男性; ( 5 )出游目的以近距離觀光、休閑為主,但度假市場正在蓬勃發展,現在中心城市周邊新興的“農家樂”就是度假旅游的雛形和低級形式; ( 6 )中心城市銀發市場和教師、學生市場是兩個原來被忽視卻孕育著巨大潛力的細分市場。

The first part is introduction , presenting this paper ' s structure , research background and so on ; the second part introduces some issues relating closely to risk , the tangency point between indifference utility curve and efficient frontier is the optimal portfolio ; the third part explores risk evaluation , this part begins with some risk factors affecting security ' s price and return , then analyzes the methods evaluating degree of risk , finally , introduces a more popular method of risk evaluation - - var ; the forth part expounds risk management , this part studies some risk control strategies correspond to specific risk mentioned above ; the last part put forward some advice contrapose issues existed in risk management in china 第一部分為緒論,介紹本文的相關背景;第二部分是與風險相關的幾個問題,等效用曲線與有效邊界的切點是投資者選擇的最佳投資組合;第三部分是風險衡量,該部分首先分析了證券與股票所面臨的風險,然后對債券和股票分別介紹,最后介紹了目前比較流行的風險衡量方法? ? var方法;第四部分為企業風險管理,這里針對上文所述的風險提出相應的風險控制策略;第五部分針對目前我國風險管理中存在的問題提出了幾點建議。

The great tour purchasing power is the drive power of promoting the region ' s tourism developmentln the regional space , scale economic and regional separation are one of the basic characteristics of promoting tourism industry , so we must arrange the regional tourism industry with a systematic method and give prominence to the central city . for its outstanding area in the regional space , central city has evident superiority in the regional ecnomic development , and has echelon between central city and its periphery scennic spots , which is the inducement mechanism of tourism industry ' s arranging , developing and advancing step by step . for the law of diminishing marginal utility and the theory of equilibrium , the max utility equilibrium of tourism consumption be at the point of tangency of undiscrepancy curve and the cost budget curve 中心城市居民巨大的出游力是拉動其周邊旅游地發展重要的內在驅動力;由于地緣關系,區域規模經濟與地域分割并存,是旅游產業運動的一個基本特征,為此必須對區域旅游經濟進行系統化布局,突出中心城市的產業中心性;因其區位條件獨特,中心城市在區域經濟發展中居于明顯的優勢,與周邊城鄉部位存在經濟發展上的梯次性,這種梯次性是區域旅游生產力布局、產業發展梯次傳動,最終整體聯動的經濟誘導機制;根據邊際效用遞減規律和旅游者最大效用均衡理論,旅游消費效用最大化的均衡在無差異曲線與開支預算線的切點(即旅游目的地選擇的最佳位置)上,且隨著邊際效用遞減,目的地選擇的最佳位置向遠離中心城市方向移動,這就是中心城市與周邊旅游地互動關系的經濟學解釋。

The paper makes research on the inner relationship of technology progress and value alternation . the two categories are essential to the being and development of human . it regards the society as a big system , goes deep into the human being , and makes human being as the point of tangency to clarify the inner mechanism of the thing ' s development from the dimensions of philosophical annotation , logical perspective and case study in a dynamic and interosculant net by systematic method 就技術進步與價值選擇這兩個對于人類生存與發展具有本質性意蘊的范疇及二者之間的內在關聯,本文運用系統論的方法,在社會這一大系統中深入到人的層面,以人為切入點,在動態的和聯系的網絡中展開生存論維度、價值學領域的哲學詮釋與邏輯透視,并進行案例分析。
