  1. According to gaseous " molecular kinetic, the mass diffusion rate is within finite value. so theoretical conclusion of mass flux ' s producing and the essential relation of flux vs. force could be drawn. with the assumption that local density states in near equilibrium and the distribution is gradual changed, the classical first pick ' s law was modified considering mass relaxation time

    根據氣體分子運動論對質量傳播速度為有限值情況下的質量流的產生及流與力之間的本構關系作了理論推導，在假定局域濃度處于近平衡態，其分佈為漸進的情況下得到了考慮質量鬆弛作用的經典fick第一定律的修正式。
  2. These microlites and richer amorphous region will benefit the polycondensation reaction of pet, the diffusion of volatile by - products, and the approach of the end - groups of pet molecular chains by forming more routeways, which may result in the higher rate of ssp

    作者認為這些更多數量的微晶體有利於固相縮聚過程中副產物小分子的擴散去除及pet大分子鏈端基的擴散接近，從而在宏觀上表現為pet mmt的固相縮聚速率大大提高。
