纸张老化前后测试的性能为MIT耐折度、撕裂度、耐破度、裂断长、白度、铜价和聚合度。

The following determinations were made on the initial and aged samples : MIT folding endurance , internal tearing resistance , bursting strength , breaking length , brightness , copper number and average degree of polymerization .

DCS中胶体物质影响纤维间的氢键结合，降低了纤维间的结合力，从而导致纸张抗张强度、耐破度和撕裂度的降低。

The DCS influenced the hydrogen bond among fibers and decreased the bond of fibers , furthermore resulted in the decrease of the tensile and burst strength . Colloidal particles could fill up spaces of paper and then decreased the tear strength .

并且在相同的打浆度下，氧碱浆的耐破度和撕裂度同Soda-AQ浆基本相同，但氧碱浆的抗张强度远大于Soad-AQ浆。

Under the same beating degree , the burst index and tear index of Alkaline-Oxygen pulp are similar to those of Soda-AQ pulp , but the breaking length of Alkaline-Oxygen pulp is much higher than that of Soda-AQ pulp .

这个测试，可用“爱门道夫”撕裂度测试机进行。

An " elmendorf " tearing tester may be use for this purpose .

加助剂后，纸页的白度、滤水性能、填料留着率、裂断长均有较大提高，撕裂度有所下降。

The paper brightness , breaking length , pulp drainage and filler retention are improved but tear index decreases when the additive is used .

建议测量纸张老化前后的耐折度、撕裂度、白度和铜价或聚合度。

Measurements of folding endurance , internal tearing resistance , brightness , and copper number or average degree of polymerization were strongly recommended for papers before and after accelerating aging .

讨论了纤维的长度、粗度和纤维的内在强度对纸页的抗张强度、撕裂度和耐破度以及纸页成形性能的影响。

This paper talked about the effects of fiber length , coarseness and strength on the properties of paper , which include tensile strength , tearing strength , burst strength and formation .

实验结果表明：当添加0.6%的羟乙基田菁胶，可使纸张的裂断长提高14.7%，耐破度提高21.6%，填料的留着率提高15.5%，而对纸的撕裂度改变较小。

The most proper dosage was determined . The results show that paper breaking length increased 14.7 % , paper burst_strength increased 21.6 % , filler retention increased 15.5 % , with little influence on paper tearing strength when 0.6 % ethoxyl_sesbania gum was added .

结果表明，过200目筛网的细小纤维在浆料中约占40%，它的存在可以使成纸的抗张强度提高120.7%，紧度提高32.2%，撕裂度提高12.6%，不透明度降低0.66%。

It was suggested that fines , passing through 200-mesh sieve , accounted for 40 % in the pulp and that with its presence , tensile strength , tightness and tear strength enhanced respectively by 120.7 % , 32.2 % and 12.6 % , and opacity decreased by 0.66 % .

结论：在常规MRI检查的基础上追加MRI关节腔造影能提高检出肩袖部分撕裂的敏感度。

Conclusions : There is a higher sensitivity in detecting partial tears with routine MRI combined with MR arthrography .
