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。 -
Radio induction is mainly studied in this paper, the traditional radio induction technology has simple structure, lower cost, convenient maintenance and higher location resolution and measuring velocity, but its anti - interference is lower. new radio induction system is proposed in this paper, it has excellent anti - radiated interference of any frequency ( it should be declared specially that it includes the anti - interference of the same frequency ) ; because of its hi gh frequency - pass function, the new radio induction system has less affection excited by the conductive interference
本論文提出的新型無線感應系統對外界所有頻段上輻射干擾（特別強調的是包括同頻干擾）具有較理想的抗干擾能力；由於新型無線感應系統起高通濾波作用，傳導干擾對它的影響可以忽略，因此新型無線感應系統具有較理想的抗干擾能力，用在定位測速中具有比傳統無線感應技術高2個數量級的精度。 -
The acoustic radiation resistance matrix is combined with the velocity vector on a vibration surface to predict the total sound power radiated from the structure
摘要利用聲輻射阻力矩陣和振動面上的速度矢量預報了結構聲輻射的總功率。 -
When the lcof is damaged, it can be repaired by its liquid core which is radiated by special illumination, and the repaired lcof can be still used to inspect the structure of composite materials. so the lcof has great application value
