病鱼排白色粘液便粘于肛门呈拖粪状。鱼迅速衰弱，直至死亡。
针对一些黏度较高，不易冷却的物料，本公司自行研究开发出了XTR型水环热切系统。
浆液粘度下降，符合了现在浆纱工艺中“两高一低”的理论。
1·Setting make have claw, inlay, mucosity.
手工制造有抓，镶，粘。
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.
结果如下：1、贵阳市白云岩地区土层较薄，土壤主要由细砂和粉砂组成，没有出现粘化特征，土壤结构性较好。
1·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。
