Before the treatment of drought stress, most of communities can be classified into following seven types with biomass of dominant species which took account of 60% in the plots: Triumfetta bartramia, Urena lobata, Cynodon dactylon, Gahnia tristis, Ageratum houstonianum, A/rtemisia argyi and Ambrosia artemisiifolia. There was no dominant species in other communities. Totally, there are 33 common species distributed in these plots.

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.

Now, due to a ley line nearby Luna on Fire Island, the crystals are growing out of control because they can draw more magic from the line.

The impacts on the diameter levels V and VI were indicated as abnormal increase of survivorship, negative values of mortality and decrease of mean life expectance whereas the impacts on the diameter levels III and IV were opposite to the levels V and VI. The survivorship curve of the Quercus variabilis population was fit with Deevey II.

静态生命表分析较好地反映出栓皮栎种群生长历史中的消长过程，清楚地透视出20年前坑木择伐对种群动态的长期影响，即径级V和VI（直径8~12 cm）存活株数异常增加、存活率提高、死亡数和死亡率出现负值以及平均期望寿命降低；而相应地对径级III 和IV带来与径级V 和VI相反的作用。

Now transmuted, we swiftly escape, as Nature escapes; We are Nature—long have we been absent, but now we return; We become plants, leaves, foliage, roots, bark; We are bedded in the ground—we are rocks; We are oaks—we grow in the openings side by side; We browse—we are two among the wild herds, spontaneous as any; We are two fishes swimming in the sea together; We are what the locust blossoms are—we drop scent around the lanes, mornings and evenings; We are also the coarse smut of beasts, vegetables, minerals; We are two predatory hawks—we soar above, and look down; We are two resplendent suns—we it is who balance ourselves, orbic and stellar—we are as two comets; We prowl fang'd and four-footed in the woods—we spring on prey; We are two clouds, forenoons and afternoons, driving overhead; We are seas mingling—we are two of those cheerful waves, rolling over each other, and interwetting each other; We are what the atmosphere is, transparent, receptive, pervious, impervious: We are snow, rain, cold, darkness—we are each product and influence of the globe; We have circled and circled till we have arrived home again—we two have; We have voided all but freedom, and all but our own joy.

我俩，我们被愚弄了这么久我俩，我们被愚弄了这么久，可现在变了，我们迅速逃走，像大自然一样逃走，我们就是大自然，我们离开这里已经很久，但是如今回来了，我们变成植物、树干、树叶、树根和树皮，我们被安置在地里、我们是岩石，我们是橡树，我们并排地生长在林中的空地，我们吃草，我们是野牛群中的两只，如大家一样自然，我们是在海中一起游泳的两条鱼，我们是刺槐的花朵，我们早晚在小巷周围散发香气，我们也是兽类、植物、矿物的粗劣斑点，我们是两只肉食的苍鹰，我们翱翔在高空，俯视下面，我们是两个灿烂的太阳，我们在像星球般平衡着自己，我们是两颗彗星，我们张牙舞爪地在树林巾梭巡，我们向猎物跃进，我们是午前午后在上空奔驰的两朵云，我们是交混的海洋，我们是两个欢乐的浪头，在互相浇泼和连环翻滚，我们是大气、明澈而善于接受，有时能穿透，有时不能，我们是冰雪，雨水，寒冷，黑暗，我们是地球上的每种势力和产品，我们绕了一圈又一圈，最后我们又回到家里，我俩，我们避免了—切，除了自由和我们自己的欢欣。

Needle-shaped clumps camel grass self-serving, a growth of the Susu, they one by one toward the wind direction, the body was tilted like difficult and stubborn stand upright in the Great wall of desert, which are especially small ones like wire-line the same root, the stone with deeply plunging to a desert, desperate to learn the distant snow-capped mountains over the bottom of infiltration of water vapor and stubbornness, for the desert, the Gobi, in order to win a trace of green earth.

针叶状的骆驼草自顾自的一丛丛、一簌簌的生长着，它们一个个迎着风的方向，身体呈倾斜状艰难而又顽强地挺立在大壁荒漠，它们把细的像钢丝线一样的根，深深地扎进戈壁的石缝，拼命汲取着遥远雪山底层浸渗过来的水气，固执地为荒漠、为戈壁、为大地争得一丝绿色。

Snow flake descends slowly and lightly to the ground, Covering silently the little lives which should not grow up in this season on the lawn.

窗外，又飘雪了，雪花一片一片地斜着飘落下来，默默地盖住草坪上那不和时机生长的小生命，天地静静地，睡吧，因为冬天已经到了。
