Home position shear tests of slope rock, point loading tests and indoor AMD simulation action tests in XingQiao concave slope had show shearing strength and coherence between body layers of quartz sandstone decrease by 13.2%~21.3% after attacked by AMD, the angle of internal friction between layers is decreased by 5.0%~7.5%, in general, AMD affects the rocks mechanical property at range of 60~100m interior the perpendicular slop. Data analysis shows: 1 The actions to slope are major focused on zone of weakness, shearing strength of slope foot and AMD centre are reduced by 52% and 64.7% separately. 2 The explosion stress wave of long distance field has obviously increasing influence to disturbance amplitude value of slope with increasing of the slope height and distance, the response of the top of slope and fault region are obvious as well as damage effect; the foot of slope is with smallest disturbance amplitude value, the disturbance amplitude value of the step close to free face is obviously bigger than the interior of slope. 3 With the coupling effect of the AMD and explosion loading, the stress distribution inside of slope mainly presents characters of explosion stress field; the area affected by AMD becomes a weak area of shearing stress.

Results of non-reducing sodium dodecyl sulphate polyacrylamide gel electrophoresis of the supernatant and aggregate precipitate formed in refolding process show that except being refolded to native egg white lysozymes, the reduced-denatured lysozymes can also form the aggregates with molecular weights being separately about 30.0 and 35.0 kD, while the reducing SDS-PAGE and the refolding results in the presence of sodium dodecyl sulphate show that these aggregates are formed chiefly through the misconnection of disulfide bonds between the reduced-denatured lysozymes, and the aggregate precipitates are formed through the non-covalent interactions between the aggregates with molecular weight being about 30.0 kD.

By studying the deformation and evolutionary sequences around the Panshan granitic pluton, east-central Yanshan orogenic belt, and 40 Ar/ 39 Ar thermochronological test and analysis,we present the structural evolutionary process of the overlying strata before pluton intruded as well as it was intruding. The sequences of regional deformation are as follows: before the intrusion of Panshan granitic pluton, the N-S trend contraction in the east-central Yanshan orogenic belt took place, which resulted in the regional EW-trending Malanyu multi-fold and Jixian thrust fault; then Panshan granitic pluton intruded into the south limb of the Malanyu multi-fold and cut-through the Jixian thrust fault; later, the reactivity of the Jixian thrust fault cut off the synclines around thePans han granitic pluton.
