【摘要】 针对原塑料波纹管拉伸试验装置既不能完全覆盖引进的技术规定又操作特别繁琐、复杂的状况 ,对其纵向拉伸载荷夹具进行了改进。新夹具既能很好地兼容国际先进技术又能达到操作十分便利之目的 ,从而明显提高了试验的可靠性和测试效率。更多还原

【Abstract】 Aiming at solving the defects of exproted Plast-Ripple-Duct tensile tester such as including all technical rules by halves and operating very complexly, the longitudinal tensile fixtures is improved. The improved instrument can both be compatible with the international advanced technology and be operated very expediently. So the dependability and efficiency of the tester are enhanced.更多还原
