试验结果表明，国产DSP帘线的尺寸稳定性好，经耐久性和高速性能试验后轮胎外直径只比试验前膨胀03%～05%，断面宽变化率绝对值为02%～07%；

The test results showed that the overall diameter of test tire after endurance and speed tests was only 0.3 % ~ 0.5 % greater than that of tire before tests , and the absolute value of sectional width changed by 0.2 % ~ 0.7 % ;

采取的主要措施是：减小轮胎外缘尺寸，外直径由808mm减至798mm，断面宽由198mm减至195mm；

The main measures are as follows : the overall diameter is reduced from 808 mm to 798 mm and the cross section width is reduced from 198 mm to 195 mm ;

通过分析，首先得出了斜交轮胎在充气时应力主要是由帘布层承担；随着裁断角度的增加充气轮胎的外直径减小而断面宽增加等结论。

Some conclusions can first be drawn from the analysis that the tension stress in an aerated bias tire is mainly borne by the cords , and that the outer diameter reduces and the section width increases when the cord angle is increased , and so on .

影响安瓿易折率最重要的因素是颈段的外直径与割痕长度，同规格间比较差异有显著性（P<0.01）。

The most important factors that affecting the rate of easy-to-break of ampoules were both the outer diameter of the neck of ampoules and the length of cutting mark . There was a significant difference compared with each other in the same specification ( P < 0.01 ) .
