双语例句
- The experimental results show that with the increase of mass fraction of SBR, the softening point increases, while needle penetration decreases.
结果表明，试样的软化点随SBR质量分数的增加而升高，而针入度却随之减小； - Theoretical and experimental analysis of sewing needle penetration force on knitted fabrics
针织物缝针穿刺阻力的分析和实验探讨 - Its main advantage is that it makes possible random sampling and analysing the needle penetration force quickly and effectively in the ordinary laboratory working condition when the sample size is large.
它的主要优点是，提供了一个快速而有效地对缝针穿刺力进行随机抽样和分析的方法。这种方法使普通的实验室在样本容量极大的情况下，同样可以进行评定工作。 - The Development and Clinical Application of Femoral Neck Needle Penetration Navigator
