西江无机碳主要来源于岩溶作用，由于受河流冲刷效应影响，丰水期HCO_3~-离子含量升高；
The Xijiang River's inorganic carbon source was major from karst process in the drainage basin. Due to the "washing effect" , the content of HCO3- ion increased in the wet season.
溜砂的主要诱发因素是地表水、地下水、河流冲刷、动荷载作用、风荷载作用、冻融作用、植物及人为因素。
The primary inducing factors of sand-sliding are surface water, ground water, stream erosion, dynamic load action, wind load action, freezing-and-thawing action, plant and man-made factors.
结果表明，该堵剂可使水相渗透率下降85%以上，油相渗透率下降25%以下，具有明显的选择性封堵作用及优良的耐冲刷性。
The results showed that, the permeability of water phase decreased 85% at least, the permeability of oil decreased no more than 25%. PDZ-1 has high selective plugging and a nice flushing resistance.
