不同用途的纸张有不同的特性要求，其中干纸强度是最主要的特性指标。所谓干强度是指风干纸的强度性质，它决定了大多数纸种的应用性质。影响纸张干强度的因素有纤维间的结合力、纤维形态与性质、纸张中应力分布和添加物质等，而纤维间结合力是决定性因素。

本文研究了不同改性淀粉对纸张干强度的影响。
The paper studies the effect of different modified starches on dry strength.
交联使纤维的湿断裂强度明显提高，湿干强度比可提高16.9%，但对纤维的热稳定性影响不大；
Wet breaking strength increased obviously after crosslinking, and the ratio of wet strength to dry strength increased by 16.9%, while there was a little impact on thermostability.
经过试验，发现该增强剂对纸的干强度有明显的效果。
The dry strength agents have showed the obvious effect to increase the dry strength.
