According to the research results of the rock quality calculation, the columnar section digitlizing, the rock mass structure diagnosis and other methods this paper used engineering limited parameters, basic structure and evolutionary structure of rock mass as the first grade indexes, proposed the technique of dynamic engineering classification of stability of mine road surrounding rock mass ? dec ?, pointed out the method of using dec results
基於圍巖質量計算、柱狀圖數字化與重組、圍巖結構診斷、采動應力作用后圍巖結構演化等研究成果，採用工程要求、基本結構、演化結構」為一級指標，提出了巷道圍巖穩定性動態工程分類技術、分類結構的表達技術及分類結果的應用方法 -
Because the photospheric temperature of carbon stars are less than 3000k and the temperature of rich - dust envelope formed by the mass loss is lower, and therefore most of the energy from carbon stars are radiated between 1 to 60um range, in which the vibrational and ro - vibrational bands of many molecules also lies, the study of infrared spectra in this wavelength range is very important to reveal chemical compositions, dust formation process, the atmospheric structure and evolutionary status of stars
碳星光球的有效溫度不超過3000k ，同時較大的質量損失率形成了富碳的塵埃殼層，以致於它的輻射能量主要集中在1 ? 60 m的紅外波段上，並且許多分子的轉動振動能譜也集中在紅外，因此在紅外波段的研究對揭示碳星化學成份及其分佈、塵埃形成過程、恆星大氣結構和演化狀態都有十分重要的意義。 -
Based on the above, the panoramic chart of debris environmental evolutionary process is presented, and breakup model main part of evolution model is introduced later, which lays a foundation for modeling comparison later. then, evolve4. 0 built up by nasa and some other models which have been used when sdem is built up are analyzed. explosion models, area to mass models and velocity models are compared and preliminary analytical results are brought out
然後，對nasa開發的空間碎片演化模型evolve4 . 0進行研究，並將它的碎裂模型與建立sdem過程中所參考的碎裂模型進行比較，從爆炸子模型、面質比分佈子模型和速度分佈子模型幾個方面進行了詳細的對比，並在條件簡化的前提下給出初步的比較結果。
