  3. It ' s the first time to explore the combustion characteristics of lpg / diesel mixing fuel engine, and find that, with the change of load and rotation, the changing trend of the ignition delay period of e10 mixing fuel is almost as identical as that of the diesel, but that of e30 mixing fuel is very different. comparing with diesel, the combustion of e10 is improved slightly, but that of e30 greatly changes ; the maximum eruptive pressure decreases ; the maximum pressure increase rate decreases ; the highest releasing heat rate increases ; the highest combustion temperature falls ; the ignition delay period extends

  4. Based on the hydrodynamic energy transport model, the influence of variation of negative junction depth caused by concave depth on the characteristics of deep - sub - micron pmosfet has been studied. the results are explained by the interior physical mechanism and compared with that caused by the source / drain depth. research results indicate that with the increase of negative junction depth ( due to the increase of groove depth ), the threshold voltage increases, the sub - threshold characteristics and the drain current driving capability degrade, and the hot carrier immunity becomes better in deep - sub - micron pmosfet. the short - channel - effect suppression and hot - carrier - effect immunity are better, while the degradation of drain current driving ability is smaller than those with the increase of depth of negative junction caused by source / drain junction shallow. so the variation of concave depth is of great advantage to improve the characteristics of grooved - gate mosfet

    基於能量輸運模型對由凹槽深度改變引起的負結深的變化對深亞微米槽柵pmosfet性能的影響進行了分析，對所得結果從器件內部物理機制上進行了討論，最後與由漏源結深變化導致的負結深的改變對器件特性的影響進行了對比.研究結果表明隨著負結深（凹槽深度）的增大，槽柵器件的閾值電壓升高，亞閾斜率退化，漏極驅動能力減弱，器件短溝道效應的抑制更為有效，抗熱載流子性能的提高較大，且器件的漏極驅動能力的退化要比改變結深小.因此，改變槽深加大負結深更有利於器件性能的提高

    如在改革開放初期，在產品市場需求旺盛和信貸市場預算軟約束的情況下，各類企業的最優決策就是採用高負債、高擴張的「負債的有限責任效應」策略來搶占市場並獲得高回報； 1989年以後，需求增速開始放緩，面臨產品市場產業集中度較低和信貸市場「信貸緊縮-不良貸款」循環陷阱導致的中小企業資金緊張的局面， 「錢袋鼓鼓」的優勢企業（尤其是那些可以通過股票市場融通資金的上市公司）紛紛採用掠奪性定價策略，試圖通過把中小企業擠出市場來擴大市場份額並獲得高收益； 1998年以後，產品市場和信貸市場形成了通貨緊縮和銀行「惜貸」惡性循環的狀況。產品市場上部分行業生產能力嚴重過剩，且由於體制等原因導致虧損企業無法退出，因此這些行業中出現了過度競爭的現象，企業總體收益的不斷下滑、負債率不斷提高以及銀行不良資產率的持續上升，又進一步加強了通貨緊縮和銀行「惜貸」的惡性循環。
