The strength and extensibility of human dura mater cold-preserved at--30 degrees--50 degrees and stored for up to 2 years were investigated. A total of 38 preserved and 5 fresh specimens were tested. The test-trials were made by using standard tensile-testing machines; The strength of preserved dura mater specimens was found to vary from 0.4 to 2 kg/mm2 and of the fresh ones--from 0.4 to 1.1 kg/mm2. The extensibility of the speciments equalled 10--30 per cent without any marked difference between the fresh and preserved ones. The duration of storage of the preserved dura mater does not affect adversely its strength.
研究了在-30℃至-50℃下冷藏长达2年的人硬脑膜的强度和伸展性。共测试了38个保存标本和5个新鲜标本。试验使用标准拉伸试验机进行；发现保存的硬脑膜标本强度在0.4至2kg/mm²之间，新鲜标本强度在0.4至1.1kg/mm²之间。标本的伸展性为10%至30%，新鲜标本和保存标本之间无明显差异。保存的硬脑膜的储存时间对其强度无不利影响。
