It was estimated pulp properties with Runkel ratio more than 1 would be harder in tension for fiber and less oriented fiber to make paper into fluffiness (Casey,1980), with flexibility coefficient less than 0.5, the paper had medium tensile strength, burst strength and folding endurance, with slenderness ratio no less than 75 that be the paper of medium tearing strength but suitable beating with per cent of wall fraction less than 40 per cent would be good paper (Rydholm, 1967) while fibers completely oriented to get higher tensile and burst strength.

牙髓腔的财产据估计超过1比率将难以在紧张、纤维少使纸纤维成蓬松型、弹性系数低于0.5，该报中等抗拉强度、爆裂强度和耐折、与细比不少于75文件中被撕裂，但适当强度击打元墙上分数占不到40%将好的文件(rydholm， 1967)而获得较高的完全纤维拉伸强度和爆裂。

The results showed that when 20% of BKP treated by PFI mill for 80 thousand revolutions added into HYP, tensile index of the hand sheet increased by 103%; z direction strength increased by 80%, and when 20% of BKP treated by PFI mill for 50 thousand revolutions added into HYP, tear index of the hand sheet increased by 120%. It indicated that BKP with rich fibrils can obviously improve the mechanical strength of HYP.

结果表明，在HYP中添加20%的经PFI磨8万转处理的BKP使手抄片的抗张指数提高了103%、z向强度提高了80%，添加20%的经PFI磨5万转处理的BKP使手抄片撕裂指数提高了120%，说明高度细纤维化的BKP能明显改善HYP的机械强度。

The transverse longitudinal paper is paper long-due to the fiber bonding ability and fiber strength of coaction, has better resistance to tear strength not easily torn, tore his face appears ragged denticular, while the vertical longitudinal paper that only short-fibre bonding strength, easy to tear, students'rooms surface.

纵向纸的横向即纸张的长边方向由于纤维间结合力和纤维强度的共同作用，有较好的耐撕裂性能，不易撕裂，撕裂面会出现参差不齐的锯齿状；而纵向纸的纵向即短边方向只有纤维结合力，易撕裂，撕裂面较整齐。

The effect of the SDT／S on the properties of NR compound was investigated The results showed that SDT／S plays the advanced role in NR compound,in order to keep the vulcanizate properties level as before may decrease some accerlator;the physical properties of overcured vulcanizate,the adhesion strength of optimum cure or overcured valcanizate between rubber and cord were improved by adding 2 phr of SDT／S to NR compound.

研究了SDT／S对天然胶胶料配方各项性能的影响。结果表明：在配方中使用SDT／S，对天然胶胶料起硫化促进作用，为保持原水平的硫化特性，可以适当减少促进剂的用量；可有效提高胶料过硫化条件下的300%定伸应力、扯断强度、邵氏硬度、撕裂性能、磨耗性能，可有效提高正硫化或过硫化条件下的胶料与帘线间的附着力。

After the addition of carbon, the microhardness in the grain boundary is about 150 MPa higher than that in the grain. The fracture type of pure Mo is intergranular fracture, the grain boundary strength of Mo-C alloy is strengthened due to the addition of carbon and the fracture type is changed to transgranular fracture, transcrystalline fracture and a large number of cleavage planes and steps are observed on the bending fracture surface. But if the carbon content is too high, the carbide precipitation will be severe at grain boundaries and is deleterioated to the ductility of the alloy.

添加碳后，合金的晶界显微硬度比合金的晶内显微硬度高150MPa左右；纯钼的断裂方式以沿晶断裂为主，添加碳后，由于合金的晶界强度得到提高，合金的断裂方式变成以穿晶断裂为主，断口上有大量的解理面，具有明显的河流状花样和解理台阶，且塑性越好的断口，撕裂岭也越多；当添加的碳含量偏高时，在晶界处产生了大颗粒的碳化物，这种大颗粒的碳化物会降低合金的塑性。

The experiment results showed that the rigidity of the composite inchlorinatedcis-1, 4-polybutadieneeased as the content of the fiber inchlorinatedcis-1, 4-polybutadieneeased, and the tear strength, the modulus at 20% in L directionalso inchlorinated cis-1, 4-polybutadieneeased; thereinto, the reinforcement effect ofnylon short fiber was the best, and the cotton powder short fiber was the worst.

结果表明，短纤维氯化顺丁橡胶复合材料随纤维含量的增加，硬度不断增大，在L向拉伸时，撕裂强度、定伸应力提高，尼龙短纤维的补强效果最好，棉粉短纤维的最差；随纤维含量增加，短纤维氯化顺丁橡胶复合材料整体耐热老化性得到了极大改善，短纤维-氯化顺丁橡胶复合材料的性能呈现明显的各向异性。
