研究不同pH值条件下，蜘蛛丝拉伸性能的变化。在酸性条件下，设置pH值梯度，比较经丝、纬丝的拉伸性能；使用同样方法，在碱性条件下，比较经丝、纬丝的拉伸性能。将实验数据应用统计学中的单因素方差分析方法分析。结果表明不同pH值对这两类蛛丝的拉伸性能的变化均有显著影响：在酸性条件下，随着pH值的升高，经丝和纬丝收缩度逐渐升高；在碱性条件下，随着pH值的升高，其收缩度逐渐降低。当pH值为7时，经丝和纬丝的收缩度最高，分别为经丝（27.00±0.60）％，纬丝（28.30±0.31）％。

The change of spider silk tension properties under different pH conditions was explored in the laboratory .The result indica-ted that the pH conditions had a significantly affection on tensile properties of radial silk and spiral silk .Under acid condition , the shrinkage degree increased gradually with the increase of pH value , the higher pH condition , the higher shrinkage degree .The shrink-age degree of radial silk reached to (27.00 ±0.60 )%, while spiral silk reached to (28.30 ±0.31 )%, when pH value is was equal to 7.As under alkaline condition , the shrinkago degree of radial silk showed an opposite tendency .The shrinkage degree showed clear negative correlation to the alkaline solution′s pH value .
