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.

An annual is best known as a plant that completes it's life cycle in a single season. Hardy annuals can survive cold temperatures and some light frost, while tender annuals cannot tolerate cold temperatures and should be planted only after there is no more danger of frost. Half-hardy annuals can tolerate some cold temperatures, but are usually killed by frost. Annuals make excellent space fillers for the perennial garden.

一年生植物最显著的一个特点就是它在一个季节内完成它的生命轮回，耐寒的一年生植物能够在低温和轻微霜冻的条件下生存，但是幼嫩的一年生植物不能忍受低温，他们只能在没有霜冻危险的条件下种植，半耐寒型一年生植物能够经受一些低温条件的考验，但是通常他们因为霜冻死亡，一年生植物能够为多年一成不变的庭院创造一个很出色的空间。

To sum up, the research for the first time ascertained INA species in apricot trees and their activities by using the rational method to imatate the temperature dropping process in frost nights--computer temperature controlling with semiconductor cooling and artificial frost box with self-recording.
