为了探讨化学成份对VPO体系孔道结构化合物结构稳定性的影响，根据酸碱平衡原理进行了合成实验设计;利用V2O5、H3PO4、H3BO3等简单的无机前驱物、乙二胺作结构导向剂，水热法合成了孔道结构钒硼磷酸盐化合物（H3NCH2CH2NH3）2（H3NCH2CH2NH2）[VⅢ（H2O）2（VⅣO）8（OH）4（H（P，B）O4）4（（P，B）O4）4（H2O）2]•3H2O（简称V9（P，B）82en）。典型的反应起始物摩尔比为n（V2O5）:n（H3BO3）:n（H3PO4）:n（en）:n（H2O）=0.89:3.50:3.50:3.60:265（pH值为6.5），在175℃、自生压力条件下恒温晶化6.5d（最终pH值为5.9）。通过电子探针、粉末X射线衍射、红外吸收光谱、原子占位度修正等方法，对产物的化学成份、物相及其结构等进行了实验研究。证实V9（P，B）82en为V9P82en的类质同象化合物，不同晶粒中B与P的含量有差别，B与P之比为0.1:7.9～2.54:5.46（原子比），但恒有V:（P+B）≈9:8。表明通过合理设计和控制合成条件，可在保持V9P82en基本结构不变的前提下通过同晶取代引入新的化学成份，并由此探讨成份与结构稳定性的关系。

在单晶X射线衍射实验的基础上，对孔道结构化合物V9P82en的类质同象物V9（P，B）82en的晶体结构和晶体化学进行了深入研究。结果表明，该化合物的晶体学数据为:P2（1）/n，a=1.43134（9）nm，b=1.01256（6）nm，c=1.83156（12）nm，β=90.280（2）°，V=2.6545（3）nm3，Z=2，R=0.0540，wR2=0.1551。结构中，沿着三个结晶轴方向发育复杂而规整的三维孔道，最大孔径达1.83nm（∥b轴），质子化乙二胺和水分子居于孔道中。硼部分替代四面体配位的磷，替代率为B8:P8=0.1838:7.8162;其中B与{P—OH}位P的替代量大于与[P-O]位P的替代量。相对于V9P82en来说，V9（P，B）82en的晶胞参数发生了变化，导致b轴增长（1.0150→1.0256nm）和c轴缩短（1.8374→1.8316nm），同时β角变小（90.39→90.278（2）°）。二者的化学计量比也不同，体现在结构与孔容的关系、电荷平衡、满足亲水2疏水作用的结晶水的数量及有机模板分子的赋存状态等方面都有差异。

The dynamic stress-fields and their distribution characteristics around boreholes in the directed crack blasting were measured with the dynamic photo-elastic laser holography apparatus and the ultradymamic measurement system. The directed crack mechanism and its mechanical model have been analysed and expounded. Through the 43 production experiments using slotted cartridges and the double triangle center cut-holes for directed crack blasting in underground rock drift, the results of which the rates of half-hole marks and efficiency of borehole,and the nonsmooth grades of the cut contours are 96%, 98% and 10cm respectively have been achieved.

Through the analysis of the occurring and developing process of the rockburst under the high strata stress, it points out that the action of stress wave is the key factor to affect the rockburst process. The characteristics of stress wave as well as its relation with the strata stress and the mechanism of its causing rockburst are explained. Finally, the preventing measures of the rockburst caused by the stress wave are put forward.

Through the theory and experiment studies on rock dynamic fracture the limit strain is used as the op timum criterion of rock cracking. The main reasons of dynamic delay fracture are the relativity of rock dynamic response with the strain rate and its lower tensile strength. The relation of yielding strain with over-stress impulse and the mechanism of tensile cracking are analysed.
