494 I seemed to be walking alone at the edge of a swamp at nightfall, the light around me glimmering, crepuscular, touched with the greenish hue presaging the onslaught of a summer storm.

那包围着我的薄暮的微光，染得有带青的颜色，预示着一个夏天的暴风雨就要袭来。微风不动，静寂寂的，但在沼泽那边高高的天上，却雷声隆隆，由小而大，而闪电时时在阴沉的天上开出花来。

The closet was a shallow cavity with a wooden rod braced across, a faded cretonne curtain on a string closing it off from the rest of the room.

Jack的衣柜空间狭窄，架了一根横向木杆，以串了绳子的褪色大花帘布开合，以隔开房间其他部分。

As on the road or at some crevice door by chance, or open'd window

I moved on a hundred years, and there was the same red sun--a little larger, a little duller--the same dying sea, the same chill air, and the same crowd of earthy crustacea creeping in and out among the green weed and the red rocks.

我又向前开了100年，还是那个红太阳，只是大了点暗了点，还是那片奄奄一息的大海，还是那种阴冷的空气，还是那群陆地甲壳动物在绿草和红岩中爬进爬出。

The thesis can be divided into five parts as follows: First, the structural characteristics of finned-pipe evaporator are analyzed. After selecting suitable microelement controller, the heat-transfer and mass-transfer processes are analyzed for every microelement under the conditions of dryness, wetness and frostiness. Based on previous equations, some parameters of frostiness are confirmed and the frost-growing model is set up under frost condition. Some hypotheses are postulated and with the help of the equation of mass-conservation, energy-conservation and momentum-conservation, the evaporation model which fits in the dynamic simulation is built, which set a solid foundation for system simulation. 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.
