Using shape function andclassical interior ballistics theory, the influence relation of the PSS model parameter affectto splitting opportunity, increasing burning surface and interior ballistics characteristicswas researched.The splitting opportunity of PSS appears ahead the academic intending, thereason is that the thickness of outside burning layer is asymmetry, the thinner area splitsearlier, and the thicker area splits later, consequently, the PSS put up progressivity burningeffect. From the practical look, the burning progressivity effect is more profitable than thatincreasing burning surface suddenly.

This paper mainly includes two parts The first part falls into three main sections. First, it analyses the formative causes of the Chinese traditional house interior display art through five aspects, including the structure and forms of Chinese traditional architecture, the productive mode of Chinese traditional society, Chinese traditional philosophy, the idea of ethics and grading and custom of Chinese traditional society. Second, it briefly introduces the history of Chinese traditional house interior display art's development. Finally, it focuses on the analysis of Chinese traditional house interior display art's design ideas and concludes that its design ideas embodies the five sides as follows: respect for nature and imitate artfully nature, practical-oriented and function incorporated into form, images of space of what the theory and practice forms, balanced natural pattern of the display, artifacts with the thoughts and respect for poetic imagery. Another part of the article further researches on the application of Chinese traditional house interior display ideas to the contemporary home display, and leads to the author's view, that is that each era should has its own character when it inherits the traditional culture. What's more, the contemporary Chinese-style home display design not only have to take over the spirit of the tradition but also have to give full consideration of the contemporary aesthetic concepts, principles and methods. In the 21st century, humanistic care is greatly proponed in the interior design. The interior display art should develop towards the ecological, personalized and comfortable direction and the cultural dimensions. It should absorb the traditional cultural elements to decorate contemporary living space. In order to upgrade the simple and primary "appearance likeness" to a higher level of "spirit likeness", it must effectively grasp the poetic imagery of space, which can reach the artistic effect of "both appearance and spirits".

本文的重点内容有两部分：一部分是从中国传统建筑的结构形式、中国传统社会的生产方式、中国传统的哲学观念、中国传统的伦理等级观念、中国传统社会的风俗习惯等五个方面简单分析了中国传统民居室内陈设艺术形成的原因；简要介绍了中国传统民居室内陈设艺术的发展过程；着重对中国传统民居室内陈设艺术设计理念的具体内涵进行了深入的分析，总结出其设计理念集中体现在五个方面，即崇尚自然与巧法造化、实用为本与文质彬彬、虚实相生的空间意象、均衡自然的陈设格局、器以载道与以境为尚；另一部分是对中国传统民居室内陈设设计理念在当代居室陈设设计中的应用作了较深层次的探讨，并提出了自己的见解，即每个时代对传统文化的继承都应该呈现出自己的特色，当代中式风格的居室陈设设计既要秉承传统民居室内陈设艺术的设计精髓，又要充分考虑当代审美观念、原则和方法的融入。21世纪，室内设计大力提倡人文关怀，具体到室内陈设艺术设计上，应该向生态化、个性化、舒适化和文化层面发展；吸收传统文化元素装饰当代居室空间，要有效地把握空间意境，使当代中式风格的居室陈设设计从简单、初级的&形似&上升到较高层次的&神似&，进而追求&形神兼备&的艺术效果。
