摘　　要：粘性水灭火剂应具有屈服假塑性流体特性 ,从而在物体表面形成稳定的覆盖层 ,并具有较低的输送阻力。屈服应力在 5Pa～ 10The viscous water extinguishant should be a pseudo-pla stic fluid with yield stress.It has strong adhesion to solid surface and low res istance when flowing through a pipe.The suitable yield stress is between 5 Pa to 10 Pa.

关 键 词：灭火剂 粘性水 流体力学 粘度 剪切作用
