tortuosities

1. The simulation results show that calculated tortuosities varies with network connectivity as well as the Thiele modulus. This work also suggests that tortuosities obtained under diffusion-only conditions can only be used under the strong reaction control conditions.
    模拟结果表明，计算出的曲折因子既是孔网络配位数的函数，又随Thiele模数的变化而不同，在纯扩散条件下测得的有效扩散系数只能应用于扩散影响不严重的反应扩散区域。

2. From beginning to end, As far as Gao Chang-hong was concerned, although his road was full of tortuosities, frustrations, loneliness and desolation, he strolled across all of this, and became more inflexible and tougher.
    对高长虹来说，尽管这条路上充满了曲折与坎坷并时常伴随孤独苍凉的阵阵痛楚，但他一步步的跨越过来，却显得更加执着与强韧。
