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.

碳星光球的有效温度不超过3000K，同时较大的质量损失率形成了富碳的尘埃壳层，以致于它的辐射能量主要集中在1—60μm的红外波段上，并且许多分子的转动振动能谱也集中在红外，因此在红外波段的研究对揭示碳星化学成份及其分布、尘埃形成过程、恒星大气结构和演化状态都有十分重要的意义。

It is equal to abandoned this part of material of nib lost and sharpens the saw-dust lost with the wooden pencil in fact, Because in 95%, the lead clothing pencil the raw materials utilization ratios of it material-saving the wrapping up core lead part removes the space of blind hole part of filling in backs end of pencil stub that are taken up of post of handle of pencil, The plumbaginous clothing material sharpens the saw-dust equivalent of material lost to consume with the wooden pencil basically, The pencil utilization ratio of raw materials produced with the timber is in 30-35%, a finished product pencil can only use two-thirds in using, Back one-third is abandoned, so the material-saving pencil is still pencil province of material-saving raw materials compared with wooden pencil.

被弃掉的笔头这部分材料实际上是与木制铅笔削掉的木屑是相等的，因为，节材铅笔它的原材料利用率在95%，铅衣包铅芯部分除去铅笔柄柱塞所占的铅笔头后端的盲孔部分的空间，铅衣材料基本和木制铅笔削铅衣削掉的木屑材料等量耗费的，而用木材生产铅笔的原材料利用率在30%-35%，一支成品铅笔在使用中只能使用三分之二，后三分之一被弃掉，所以节材铅笔与木制铅笔相对比还是节材铅笔节省原材料。

Both the rarefactive and compressive waves can be determined by plasma parameters including the temperatures of dust fluid, ion and electron, as well as the non-thermal ions, and the number densities of dust particle , ion and election, etc.

而稀疏孤波和压缩孤波的存在则完全取决于尘埃等离子体参数，如：尘埃流体、离子和电子的温度，非热离子的快离子数以及尘埃颗粒、离子和电子的数密度等。
