The long-term existing theory of wood collapse which was thought to be caused by "negative pressure" resulted from capillary tension in the water capillaries was called in question.
长期以来,木材皱缩现象一直被认为主要是因为木材中液体毛细张力产生的“负压强”压溃细胞壁造成的,该文对此提出了质疑。
Reduction of interfacial tension can increase capillary number, accordingly, reduce saturation of irreducible oil, enhance ability of oil recovery.
界面张力的降低可提高毛管数,从而使残余油饱和度下降,提高原油采收能力。
The results show the surface-active agent used by the experiments can reduce the capillary pressure and the surface tension between gas and liquid obviously.
研究结果表明实验采用的表面活性剂能明显降低毛细管力和气—液表面张力;
The viscosity and surface tension was improved by gel structure of bentonite colloid, so the capillary force is increased and therefore the wet compression strength is improved.
凝胶结构提高了粘结液相的粘度和表面张力,毛细力增大,生球抗压强度提高。
It is the formation of a non-gravity spread to the surrounding water, flowers in crystal formation, the water movement is mainly the surface tension force or the capillary-driven results.
它的形成是非重力水向四周扩散,在晶花生成时,水的运动主要是其表面强力或毛细管张力驱动的结果。
