中文摘要:
      用孟山都加工性能试验机(MPT)在温度为70～130 ℃、表观剪切速率为50～631 s-1的范围内测定不同用量的高芳烃油、4#橡胶油、石蜡烃操作油用于高耐磨炭黑填充天然橡胶胶料中时胶料表观剪切应力的变化。对具有第I类流动曲线的体系，通过计算机处理数据，建立了软化指数(SI)同软化剂用量(P)的数学关系式，表明了温度及表观剪切速率对SI-P关系的影响。
英文摘要:
      The change of the apparent shear stress in the HAF loaded NR compound with different level of high aromatic oil，4#rubber oil and paraffin oil was determined by MPT(Monsanto Processiblity Tester)at the temperature of 70～130 ℃ and at the apparent shear rate of 50～631 s-1.For the system with the first group of flow curves，the data were processed with a computer before a formula for softening index(SI) and loading level of softener(P) was established to show the influence of the temperature and the apparent shear rate on the SI-P relation.
