在二级轻气炮动高压装置上用电探针技术测量了吉林球粒陨石(H5)和南丹铁陨石(ⅢCD)的冲击压缩线,然后分别选择几种可能适用于普通球粒陨石和铁陨石状态方程的数学表达式,并确定了状态方程中的有关参量值.从状态方程的P(V)关系曲线与实验数据的比较来看,吉林球粒陨石最适合采用普适状态方程形式,而南丹铁陨石则最适合采用三项式状态方程形式.吉林球粒陨石的普适状态方程参量K_(OS)=48.10GPa,K’_(OS)=4.13.南丹铁陨石的三项式状态方程参量Q=41.2353lGPa,q=12.27179,这是吉林球粒陨石和南丹铁陨石状态方程的首次报道.
The impact compression lines of Jilin chondrite meteorite (H5) and Nandan meteorite (ⅢCD) were measured by electric probe technique in a two-stage gas-fired high-pressure device, and then several kinds of impact compression lines that were suitable for ordinary chondrules and The mathematical expression of the state equation of iron meteorite and the related parameter values of the equation of state were determined.Comparing the P (V) curve of the state equation with the experimental data, the most suitable form of the universal chondrite is the universal state equation , While the Nandan iron meteorites are most suitable for using the form of the equation of state equation.The universal state equation parameters of Kernel chondrites K_ (OS) = 48.10GPa, K’_ (OS) = 4.13.The three Equation equation of state parameters Q = 41.2353lGPa, q = 12.27179, which is the first report of the state equation of chondrite and nandan meteorite.
