简介：开发shear变瘦代替血的非牛顿的液体在自从血是展出的shear变瘦nonNewtonian液体，设计的biomedicine的研究是合乎需要的粘滞、有弹性性质，并且通常在大体积不可得到。有不同集中和温度的水的Xanthan口香糖的rheological性质在现在的纸被学习。结果证明水的Xanthan口香糖是显示的非牛顿的液体显著砍变瘦行为并且是合适的血类似物液体。在之间有一种幂定律分发关系砍强调并且砍率，并且答案集中越高，它显示越多强烈砍变瘦行为。有解决方案温度减少或与解决方案集中的水的Xanthan口香糖增加的粘性值在线性增加。而且在37的温度，有0.4和0.6的集中的水的Xanthan口香糖在rheological性质最好匹配人的血。根据重新适合，与温度和concentrition改变的粘性表示被获得，并且Xanthan口香糖答案的稳定性被讨论。
