According to the above referred quantitative standard as an HEDC and stabilityrequirement, 1,2,3,4,5,6,7,8-octanitroadamantane, 1,2,3,4,5,6,7,8,9-nonanitroadamantan-e and 1,2,3,4,5,6,7,8,9,10-decanitroadamantane are worth recommending as potentialHEDCs, and this denies the foreigners conclusion obtained from group additivity thatthe PNA with 11 nitro groups is the target compound.

按照前述HEDC的定量标准和稳定性要求，发现1，2，3，4，5，6，7，8-八硝基金刚烷、1，2，3，4，5，6，7，8，9-九硝基金刚烷和1，2，3，4，5，6，7，8，9，10-十硝基金刚烷三种化合物是值得推荐的潜在HEDC，从而否定了国外前人由基团加和法得出的十一硝基金刚烷是PNAs系列最佳HEDC目标物的结论。

In addition nC〓, nC〓, two isomers of C〓 sterene and three isomers of C〓 isoprenoid hydrocarbons were also identified from aliphatic fraction of pyrolyzed product at 200℃. After pyrolyzed at 300℃, the main aliphatic hydrocarbons were normal alkanes ranged from C〓 to C〓, with C〓 as the main peak and C〓 as the second main peak. Meanwhile, pristane, phytane and C〓 sterane were also detected. In the pyrolysates at 400℃ and 500℃, the content of saturated hydrocarbons decreased, the range of normal alkanes distribution became narrow and the main peak was nC〓. Low concentration of C〓-C〓 steranes was detected and the content of C〓-C〓 increased more.
