( 5 ) the ability of carry out a porous shock compression experiments with uncertainty less than 20 % has been had , and then there is a possibility to obtain at high pressure with uncertainty less than 10 % . ( 6 ) another method to get , utilizing the method 3 p _ ( c ) and shock compression data , has been investigated . it has been shown preliminarily that there a simple phenomenal project to calculate by utiliaing this method
第三方面，考察了以实验数据计算的一些情况，获得的主要结果为( 5 )就目前所能达到的实验精度，开展具有适当初始疏松度的疏松材料的冲击压缩实验可提供不确定度10的高压实验测量值； ( 6 )利用本文给出的冷压与冲击压缩实验数据联立的方法计算了大量金属的宽热力学范围的男，初步的分析表明，以该方法为基础可形成一种更多保留实验信息的gruneisen系数唯象计算方法。
