The permeability (P), diffusion (D) and solubility (S) coefficients for polymers and coatings are key parameters that affect a polymer's barrier performance.
聚合物和涂层材料的渗透系数（P）、扩散系统（D）和溶解系数（S）是影响聚合物阻隔性能的关键参数。
Results (1) Permeability of blood brain barrier was increased in burn and burn with NE stimulating rats, with significantly statistical difference compared with normal control group (P<0.01).
结果（1）烧伤大鼠和NE刺激后的烧伤大鼠血脑屏障通透性增加，与对照组比较差异有统计学意义（P<0.01）。
Compared with the K-P method, it is found that the results of two methods are accordance with the increase of the barrier width.
此法比k - P方法简便易行，而且随着势垒宽度的增加，两种方法所得结果趋于一致。
