本文重點是對蒸發器建立動態模擬模型，並對製冷劑側和空氣側參數進行穩態和動態模擬，同時對蒸發器在不同蒸發溫度下的製冷量進行了動態模擬，而且對影響蒸發器性能的主要參數（空氣側入口風速、入口含濕量等）進行了分析和計算。 -
The variations of sea ice in the arctic ocean are simulated by using a improved high resolution hibler dynamic - thermodynamic sea ice model during 1979 - 1998. the model is driven by surface atmospheric and oceanic forcing consists of geostrophic winds, surface air temperature, specific humidity, and longwave and shortwave radiative fluxes provided by international arctic buoy program ( iabp ). the simulated results show that arctic sea ice have noticeable seasonal and annual variability
利用一個hibler海冰熱動力模式，在改進了其熱力部分和改變模擬范圍以及提高解析度的基礎上，以北極國際浮標計劃（ iabp ）提供的1979 - 1998年間逐日變化的日平均海平面氣溫場，濕度場，長短波輻射場，風場，洋流場，海洋熱流量場為強迫場，模擬了上述20年間北極海冰的時空演變。 -
The elements of vorticity, divergence, specific humidity, moisture flux divergence and k index etc. were benefited to the form and development of storm rainfall over the rainfall region
降水區上空的渦度、散度、比濕、水汽通量散度、 k指數等要素有利於暴雨的形成和發展。 -
The results of numerical experiments, using the four - dimensional variational data assimilation system of the nonhydrostatic mesoscale model mm5, show that : the tangent linear model and adjoint model conducted by keeping the " on - off " switches the same as the basic state, can provide a good approximation of the first - order information to the nlm perturbation and a good descent direction for the minimization procedure ; switching on and off at every other time step in the kuo cumulus parameterization scheme do n ' t impact the convergence rate of cost function ; the existence of the switches do n ' t impact improvement to the mm5 model rainfall prediction because that not only specific humidity, but also wind, temperature and pressure are assimilated into the model
非靜力中尺度數值模式mm5的四維變分資料同化系統進行的數值試驗結果表明： 「開關」變量保持與基態一致，所構造的切向線性模式能夠提供關于非線性模式擾動的一階近似，伴隨模式所計算的梯度值能夠為最小化過程提供較好的下降方向；郭氏降水參數化方案中對流每隔一個積分步的交替發生並不影響目標函數最小化的收斂速度； 「開關」變量的存在也不影響將風、溫度、氣壓和比濕結合起來同化對mm5降水預報準確性的提高。 -
We also analyzed the elements of vorticity, divergence, specific humidity, moisture flux divergence, wind - field, wind shear, maximum lifting speed and so on in the snow - storm of north - east china, found that they are favorable for and benefited to the formation and development of snow - storm
對2000年1月同一天不同時刻發生在西北和東北的一場暴雪過程進行了對比分析，發現兩地暴雪雖發生在同樣的大尺度環流背景下，但卻在很多方面有不同之處。
