The researches of volcanic earthquake activities recorded at Tianchi Volcano Observatory ( TVO ) since 1999 showed that the volcanic earthquake activities changed their features before or after the occurrence of the intermediate-deep earthquakes , magnitude 5.0 or larger than that , in the Northwestern Pacific Ocean .

对1999年以来长白山火山观测站记录到的火山地震活动进行了研究，发现在西北太平洋5.0级以上中深源地震发生前后，均有火山地震活动发生变化。

HTB with the largest micropore volume , the widest micropore size distribution , the highest fractal dimension value and the smallest average pore diameter is favorable for doping process , and characterization properties of ATB and TBO in this investigation are just between TVO 's and HTB 's.

HTB粉末具有最大的微孔体积，最宽的孔径分布，最高的分数维维数和最小的平均孔径，对于掺杂工艺来说是有利的。
