摘要該文從國有資產流失案件入手，分析流失的原因，評析了用適用信託制度解決海外資產管理問題的優點和局限性，提出對海外資產的管理需要綜合法律手段來調整，才能真正做到實現海外資產保值增值。Important missing aspects are : turbulent flow, numerical discretization techniques specially the relevant and difficult topic of numerical treatment of advection and related numerical methods of solution, variable property fluids, boundary layers, stability, etc. rather, it focuses on more primitive and fundamental issues of numerical treatment of advective equation and proper formulation of initial boundary value ( ib vp ). numerical problems associated with advective dominated transport include spurious oscillation, numerical dispersion, peak clipping, and grid oriention. however, the key of numerical solution of three - dimensional advective problem is searching for a high - precision interpolating function, which can keep the computational stability and low damping
3 、針對三維純對流方程提出了實用的擬協調單元模式，並與線性插值模式和協調單元模式比較后表明，在物理量大梯度變化的情況下，線性插值模式會產生較大的數值阻尼，導致解的失真；協調單元模式具有極高的計算精度和良好的計算穩定性，還可較好地克服數值阻尼，但由於計及物理量的二階導數項，計算工作量大，邊界條件給定尚存在一定的困難；而擬協調單元模式不僅具有協調單元模式計算精度高的優點，還避免了物理量的二階導數項，可大大地減少計算工作量。This paper introduces a method of taking the first truly seawater heating source pump system to solve the problems of high thermal conductivity and frequently on - and - off going in operation process by frequent irrigation projects
