英文
hoarfrost point-
On this morning of the great snow ， perchance ， which is still raging and chilling men ' s blood ， i bear the muffled tone of their engine bell from out the fog bank of their chilled breath ， which announces that the cars are coming ， without long delay ， notwithstanding the veto of a new england northeast snow - storm ， and i behold the plowmen covered with snow and rime ， their heads peering ， above the mould - board which is turning down other than daisies and the nests of field mice ， like bowlders of the sierra nevada ， that occupy an outside place in the universe
在特大風雪的黎明，風雪還在吹刮，凍結著人類的血液呢，我聽到他們的火車頭的被蒙住了的鐘聲，從那道霧? ?的凍結了的呼吸中傳來，宣告列車來了，並未誤點，毫不理睬新英格蘭的東北風雪的否決權，我看到那鏟雪者，全身雪花和冰霜，眼睛直瞅著它的彎形鐵片，而給鐵片翻起來的並不僅僅是雛菊和田鼠洞，還有像內華達山上的巖石，那些在宇宙外表佔了一個位置的一切東西。Second, the starting and stopping behaviors under disturbed condition are analyzed and calculated by using the dynamic concentrative parameter model, which gives some advice to better prescribe refrigeration system and set theoretic foundation for carrying out automatic control of refrigeration system. third, the normal running process is analyzed and calculated by means of rational matching theory, which gives some advice on how to better understand the parameter change under steady state and the affection of inlet - parameter on evaporator. fourth, the simulation software with dynamic characteristic is designed, which can be applied to calculate thernio - parameter of cryogen, air humidity and frost thickness under different initial and boundary conditions, and to carry out dynamic simulation under conditions of dryness, wetness and frostiness, at the same time, to achieve detection and simulation at any stage from starting to stopping
本文的主要內容如下： 1 ）對翅片管蒸發器結構特點進行分析，選取適當的微元控制體，就干、濕和霜工況下對每個微元分別進行傳熱傳質分析，基於經驗關系式確定霜的有關參數，對于霜工況下的霜生長建立模型，經適當假設，運用質量守恆、能量守恆和動量守恆方程建立適合動態模擬的蒸發器數學模型，為系統模擬奠定基礎； 2 ）對蒸發在大擾動下的開、停機過程，運用動態集中參數模型進行分析和計算，為更好地描述製冷系統運行的全過程奠定基礎，同時也為製冷系統實現自動控制提供一定的理論基礎； 3 ）對蒸發器正常運行過程，運用動態分佈參數和參數間定量耦合的觀點來分析和計算，為更好地了解穩態工況下各點參數的變化情況及各入口參數對蒸發器動態特性的影響即蒸發器性能對各參數變化的敏感性； 4 ）編寫翅片管蒸發器動態特性模擬計算程序，可以計算不同邊界條件和初始條件下的製冷劑熱力參數、空氣溫濕度和霜厚度分佈場，實現對翅片管蒸發器在干、濕和霜工況下的動態模擬。Frostbite injury or destruction of skin and underlying tissue, most often that of the nose, ears, fingers, or toes, resulting from prolonged exposure to freezing or subfreezing temperatures
