查询词典 structural formula

The results show that the experimental results are in good agreement with the values of viscosity in a part of temperature range that has been reported, with the relative error of less than 2.5%; In the process of ascent and descent temperature, the irreversible phenomenon of the curve of viscosity versus temperature V presents interzone characteristic, and the break of viscosity at critical temperature reflects jump change of melt structural information; It is one to one correspondence between viscosity and atomic size, and this relation is consistent with the Hall-Petch formula in expression way.

结果表明：实验结果与已报道的部分温度区间内的黏度值基本一致，相对误差低于2.5％；升温和降温过程中，黏度－温度关系曲线V的不可逆现象具有区间特征，临界温度时黏度的突变反映出熔体结构信息的跳跃变化；黏度与原子集团尺寸之间存在一一对应关系，该关系在表达上符合Hall-Petch公式。
