And the tensile properties of coated fabric and uncoated fabric were tested, after coating, tensile strength of fabric is raised, but breakingelongation and trapezoid tearing strength are reduced.

同时讨论了涂层前后织物拉伸性能的变化，涂层后织物的拉伸强力增加，断裂伸长率和梯形法撕裂强力降低。

The effects of beating and pressing on the tearing strength of paper also have been investigated. The pulp materials of the experiment are masson pine, reed and straw.

本实验从纤维特性——纤维长度、粗度和纤维本身强度方面研究了对纸页撕裂性能的影响，也研究了打浆、压榨对纸页撕裂强度的影响。

However, the physical and mechanical properties of the fabric are influenced too. That is, gas permeability and whiteness of the fabric decline, the breaking strength and tearing strength change little.

但同时涤纶织物的物理机械性能也受到了不同程度的影响,其中透气性、白度均有所下降,断裂强力、撕破强力变化不大。
