聚四氟乙烯

Meanwhile a composite material has been used to simulate successfully the stochastical crack rock which was performed through adding crack blend, polytetrafluoroethyleneflakes, to geomechanical material.

同时，使用一种复合材料模拟了随机裂纹岩石，即通过将裂纹片掺合料，聚四氟乙烯薄片，加于地力学模拟材料而实现。

Once the hernia defects are visualized, a polypropylene or expanded polytetrafluoroethylene biomaterial is then inserted and secured to the transversalis fascia and/or Cooper's ligament with tacks or staples. The material is of a size that completely covers the myopectineal orifice.

一旦缺损区出现于视野中，送入聚丙烯或可延伸聚四氟乙烯网状补片，并将其固定于腹横筋膜上和/或Cooper韧带上，补片的大小以完全覆盖住内环口为宜。

The result is that the crystal structure of the sample irradiated at the dose of 1×10^5 Gy is of an obvious damage while the structure of the unirradiated sample is crystal band.

结果表明，辐照前聚四氟乙烯样品的表面是规则的带状晶形结构，经1×10^5Gy辐照后样品的晶状结构遭到了明显的破坏，向非晶态转变显著。
