論文的模型探討了下列因素和中國信貸配給現象之間的聯系:商業銀行對信貸風險的態度變化,在辨別和控制信貸風險上開始投入大量的成本,這一過程會導致信貸配給;商業銀行對與法治環境相關的交易成本和抵押品清償價值的日漸關注會導致信貸配給;宏觀經濟緊縮時期資產價格下降會導致信貸配給;商業銀行經營目標函數偏離利潤最大化,近幾年金融業改革過程使商業銀行目標函數發生變化,這一變化過程可能導致信貸配給;在市場分化的條件下,收益水平低的市場會遭受信貸配給;在經濟下滑時期,商業銀行尤其會對高風險市場配給信貸;利率市場化使商業銀行的存貸利差至少在一段時間內縮窄,利差縮窄可能加重信貸配給的程度:在利率市場化條件下,弱勢借款者,包括中小企業,遭受信貸配給的程度可能得到緩解,但支付的貸款利率水平將會升高。The system is able to efficiently increase temperature and meet crop requirement of temperature for yield. in researching and designing solar energy conserving system in soil for active greenhouse, it adopts instrument of rhlog, tests temperature of six layers to soil temperature, and draws various curve of temperature. it shows the system can efficiency increase soil temperature and reduces change range of temperature in greenhouse in wintertime

文摘:生物入侵是不均衡世界的一個永恆話題,尤其是當人類有意或無意地引入物種后.很多引入顯然是無害的,但另外一些則有著嚴重的後果,會給入侵地的生物以至於整個生物群落造成影響.本文總結了分佈區擴張的常見模式,概述了它們對遺傳多樣性和種群結構式樣所造成的影響.描述了如何根據以一批遺傳標記所得到的遺傳多樣性式樣來推斷入侵途徑,來揭示伴隨擴張選擇和漂變在形成種群遺傳樣式中的作用.本文對日益增多的群體遺傳學方法進行了總結,這些技術可以用來在不同的時間尺度上推斷種群規模所發生的巨大變化(瓶頸效應及種群擴張) .最後,我們以歐洲櫟癭蜂(膜翅目,癭蜂科,癭蜂族)一系列入侵的數據為例對一些方法進行了說明.從500 10000年的時間尺度上,多態的等位酶位點上等位基因頻率的數據表明: 1 )遺傳多樣性沿入侵路線呈不斷下降的趨勢,支持了冰河期避難所作為遺傳多樣性中心的作用; 2 )入侵地區的種群與該物種原產地的種群相比,遺傳上的分化更為強烈.這種種群結構在空間上的變異可能是被櫟癭蜂開發的資源尤其是櫟樹寄主在斑塊上出現變異的反映Firstly, the resault of daily calculation about all kinds of potential instability parameter in a month show that, as a vertical integral potential instability parameter, cape ' s daily variation corresponded to the severe convective storms " occurrence
