dispersion parameter的用法和样例：
例句
- The perturbation develops quickly and propagates reversely and slowly against the basic flow, when the stability parameter is smaller.
当稳定度参数较小时，扰动发展较快，并且也以很小的速度倒转。 - Besides, it can automatically control the resolution parameter during the clustering proceeds and overcome the sensitivity to noise and outliers.
该算法还能在聚类过程中自动地确定解析度参数，克服了对于噪声和外围点的敏感性。
