  1. The experimental results of the flow characteristics of the mmc heat sink indicate that the critical reynolds number signifying the transition from laminar flow to turbulent flow is in advance ; under the same experimental conditions, the variation in entrance direction of the microchannel inlet and outlet has little effect on the microchannel ; the experimental values of the friction factor of the de - ionized water in a microchannel agree well with those calculated using the theoretical laminar formula ; furthermore, a comparison of the experimental results and simulation results shows that navier - stokes equation and rng - turbulence model can be used to model the laminar and turbulence flow regions in a microchannel ; meanwhile, the correlations of the flow resistance in the turbulent flow regions for the de - ionized water as the working fluids are obtained from experiments

    對歧管式單通道熱沉流動特性的研究結果表明，微通道內流體流態由層流向紊流轉變的臨界雷諾數提前;改變流體的進出口方向對熱沉總壓降造成的影響很小;摩擦系數的實驗值與理論值較接近;數值模擬結果能夠與實驗值較好吻合;並由實驗給出了紊流區流動阻力的實驗關聯式。此外，選用十二烷基硫酸鈉（ sodiumdodecylsulphate ， sds ）以及烷基多糖苷（ alkylpolyglycoside ， apg ）作為減阻添加劑，研究了表面活性劑添加對微通道流動特性的影響。
  2. Although irrigation could enhance output greatly, not all farmers could sink wells because of the economy and infield scales. in the first half of the 20th century, in north china, villages had a lot of custom using and maintaining wells, such as sharing the irrigating wells or borrowing. wells for drinking could use freely, which meant anyone could get water for drink from any well and the own

    灌溉雖可大幅度地提高作物產量，但灌溉井的開鑿與農戶經濟狀況及農戶所經營的耕地規模有關，並不是所有農戶都可以開鑿灌溉用井，在二十世紀上半葉華北村落中存在著眾多的關於水井的使用和維護的習慣做法，如對灌溉井的共用或借用
  3. In this thesis, a closed brayton cycle is proposed, in which the supercritical lng is taken as its cold sink and an industrial waste heat as its heat source. in this thermodynamic system, the heat releasing process in the brayton cycle is a inconstant temperature process and it matches the process of lng boiloff well, therefore, the exergy loss in the heat transfer process is reduced. at the same time, waste - heat can be utilized effectively in the system

    一、利用lng冷（火用）與工業余熱的閉式brayton循環熱力分析本論文討論了lng在超臨界壓力下汽化時，選擇無相變的brayton循環與之匹配，因為brayton循環的放熱過程為變溫過程，與lng的汽化過程有可能做到較好的溫度匹配，減少換熱過程的不可逆損失。
  4. In the numerical solution algorithm, the method of characteristics, analytic method and galerkin finite element method ( galerkin - fem ) can be chosen to solve the advective equation, diffusion equations, reaction ( source / sink ) equations, propagation equations and pressure poisson equation, respectively. the developed new algorithm has been verified using analytical solution of circular conduit flow in a reynolds number range of 100 < re < 1 000 and experimental data of the laminar flow over a backward - step facing step. the flow properties are well characterized by this three - dimensional numerical model

    本論文在評述三維粘性流動數學模型已有研究成果的基礎上，著重在數值計算方法的選擇和定解條件的給定對數學模型計算結果的影響進行了研究，並首次提出了求解三維純對流方程的高精度的擬協調單元法，建立了三維低雷諾數re流動的數學模型，並在圓管流動、臺階突擴矩形管道流動中得到驗證和應用。
  5. I should sink a well down here and retire

    我在這兒挖口井退休算了
  6. As lack of sufficient state revenue, the debt burden will make local public finance sink into inadequate liquidity crisis, which will become a major affecting stead operations of local public finance as well as sustained growth of local economy. under these circumstances, the research on the debt of local government become an urgent need

    近年來，隨著經濟增長趨緩，地方政府債務負擔日顯突出，在缺乏收入保障的條件下，地方政府債務積累會使地方財政陷入清償能力不足的危機，成為沖擊地方財政運行的重要風險因素，制約地方經濟社會的可持續發展，在此情況下研究地方政府債務問題顯得尤為迫切。
