2. Soil of dolomite areas in Guiyang is thin , soil component are mainly thick and thin sand , and there was not mucosity characteristic, soil structure is better.
3. Mathematic model of hydraulic breaker piston movement. A non-linear hydraulic breaker model was built, in which mucosity resistance and leakage was taken into account.
建立了包含粘性阻力和泄露等因素在内的液压破碎锤非线性模型。

4. The mechanism might be related to reducing cholesterol, reducing blood mucosity, improving red cell transformation and reducing its aggregation to increase blood flow speed of vertebrobasilar artery.
机理可能与降脂、降血粘度、改善红细胞变形与降低其聚集能力,以提高椎基底动脉血流速度有关。
