    高壓旋噴注漿技術具有適用范圍、適用地層較廣，施工方便，耐久性好，材料廣闊等特點；其加固地基機理主要是通過流動壓、噴射流的脈動負荷、水塊的沖擊力、空穴現象、水楔效應、擠壓力、氣流攪動等效應形成水泥固結體與樁間土的復合地基，從而提高地基承載力，減少沉降變形。
  2. Under this condition, this thesis offers a study on cavitation characteristics caused by two main accidental conditions : power off and system fluid off

    本文即是針對動力失靈和系統斷流兩種主要事故工況下，所引起的動力系統中空穴的特性作以研究。
  3. The entering of the tourist and lamp - light gave much energy to furong cave and the temperature in the cave rised slowly. the different temperature between the outer and the inner as the air circulation, would make the cave wet seriously in the summer and dry in the winter. the density of co2 would go up because of piston - effect, cave depositing and the tourists " entering

    遊人的進入和洞穴燈光的使用，給芙蓉洞內帶來了大量的能量，致使洞穴空氣升溫；由於動內外的溫度差和空氣的流通，開放的洞穴出現夏季高濕，冬季乾燥的變化現象； co _ 2的濃度會因為活塞效應、洞穴沉積和遊人的進入而升高，但影響最大的還是遊人，當遊客量較大的時候，洞穴co _ 2的濃度會隨遊人進入的數量增加而明顯升高，洞內co _ 2含量峰值記錄最高出現了6200ppm的記錄。
  4. Closer throttling, creating higher pressure drops may cause cavitation or excessive velocities which could cause high noise levels, vibration and possible damage to the valve or adjacent piping

    如果節流較小，將因此產生更高的壓降將可能導致空穴現象或超快流速，從而導致噪音太高，振動劇烈，可能損壞閥門或相鄰的管路。
  5. Based on the hydrodynamics energy transport model, the degradation induced by donor interface state is analyzed for deep - sub - micron grooved - gate and conventional planar pmosfet with different channel doping density. the simulation results indicate that the degradation induced by the same interface state density in grooved - gate pmosfet is larger than that in planar pmosfet, and for both devices of different structure, the impact of n type accepted interface state on device performance is far larger than that of p type. it also manifests that the degradation is different for the device with different channel doping density. the shift of drain current induced by same interface states density increases with the increase of channel do - ping density

    基於流體動力學能量輸運模型，對溝道雜質濃度不同的深亞微米槽柵和平面pmosfet中施主型界面態引起的器件特性的退化進行了研究.研究結果表明同樣濃度的界面態密度在槽柵器件中引起的器件特性的漂移遠大於平面器件，且電子施主界面態密度對器件特性的影響遠大於空穴界面態.特別是溝道雜質濃度不同，界面態引起的器件特性的退化不同.溝道摻雜濃度提高，同樣的界面態密度造成的漏極特性漂移增大
  6. The cavitation flow in a nozzle at steady spray of a diesel engine was simulated, and the formation mechanism and distribution of cavitation inside the nozzle were analyzed using mixed multiphase flow model coupled with cavitation model

  7. Compared with green light - emitting device, blue oled has many problems such as brightness, efficiency, stability, and color saturation, in this study we investgaited the blue oleds systemically : 1 ) double heterosturcture oled was charaterized. due to the introducing of electron transport layer alq3 and hole - blocking layer balq3, the energy matching was more reasonable and the carrier injecting was more effective in the double - layer device. the maximum efficiency and luminance of this device attained to 1. 90 lm / w and 10, 000 cd / m2, respectively

    其次，由於一直以來藍光oled器件的研究處于相對落後的狀態，其發光亮度、效率、穩定性和色純度都無法綠光器件相比，所以本論文在以下幾個方面對藍光器件的性能進行了系統的研究: 1 ）研究了雙異質型藍光oled器件，由於本研究引入了空穴阻擋層，使得載流子的復合和激子的擴散被限定在發光層內，器件的發光效率達到了1 . 90lm / w ，最大亮度達到了10000cd / m2 ，比傳統結構器件的效率和亮度提高了約一個數量級; 2 ）制備了結構為ito / npb / balq3 / alq3 / mg : ag的oled器件，研究發現，當改變各有機層厚度時，器件的電致發光光譜發生了從綠光到藍光的移動。
