Recently, as preservation of cultural property is gaining more and more public attention, the important role of conservation treatment on Paintings of Traditional Buildings is accepted. But researches and studies on the related techniques and methods of conservation for Paintings on Traditional Buildings remain deficient in Taiwan. In addition, records and descriptions in projects adapting conservation treatment are poorly listed. Lacking both academic and empirical references, it often misleads staff in the projects to underestimate importance of conscientious and careful training to do conservation. One problem is the belief to easily replace conservators with painting craftsmen to work on conservation treatments.

然而，在文化资产保存观念渐为大众所关心与接受下，彩画修护逐渐为传统建筑修护工程所重视，但国内关於彩画修护技术、方法的论述几乎没有，尤其是近年来在少数采行修复方法的彩画修护案例中，对修复部分的相关纪录与描述更是寥落晨星，以致许多参与修护工程的相关人员对彩画修护方法有极大的误解，误以为不需经过特殊、严谨的「修复」训练，即能以一般传统建筑彩画的施作工法来从事「修复」工作，又或误以为修复师可以替代彩画匠师来进行传统建筑彩画的施作……。

Moreover, we consider that the mass of an atom contains two parts: the intrinsic-mass and the binding-energy-mass, the former mass cannot be converted into energy, while the latter mass can be converted into energy directly in accordance with the mass-energy relation. Besides it\\\s shown clearly that the so-called mass-energy conversion is essentially the release of binding energy in the atoms.

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.
