聚四氟乙烯

It is insulated with thermo and chemical resistant clear Teflon material.

它绝缘与热和化工抗性清楚的聚四氟乙烯材料。

The support insulators should be made of materials with very high resistance, such as Teflon.

支撑用的绝缘体应当用电阻非常高的材料，如聚四氟乙烯或陶瓷来制作。

When necessary, can also be used to make Teflon and other materials, gasket.

必要时也可用聚四氟乙烯等材料作垫圈。

The reparing high molecular material was divided into absorbable and unabsorbable material,the former included polyglycolic-acid and polyglaction,the later consists of polypropylene polyester and expanded polytetrafluoroethylene.

人工高分子修补材料主要有可吸收和不可吸收两大类，前者有聚羟基乙酸和聚乳酸羟基乙酸两种，后者有聚丙烯网、膨体聚四氟乙烯片及聚酯纤维网。

Compared with formerly used crude mica and polyquadrifuorethene, Fluorocrytal Mica with its purity has high body resistivity (100 times than crude mica), low loss in high frequency medium ( 1 time smaller than crude mica), moderate dielectric constant, safe use temperature up to 1100℃, good intensity, elasticity, unaging, and consequently good electric stability.

与原来使用的天然云母和聚四氟乙烯比较，氟晶云母由于质地纯净，具有较高的体电阻率（比天然云母高约1000倍），高频介质损耗低（比天然云母小1倍），介电常数适中，且安全使用温度可达1100℃、强度好、富有弹性、不易老化，因而其电性能非常稳定。

The surface wettability and surface structure of poly treated with remote O2 plasma were studied.

研究了远程氧等离子体改性聚四氟乙烯的表面润湿性与表面结构的关系。

Note:"F" can also be used to stand for Teflon plus glass wire impregnated sheath.

注： 聚四氟乙烯+玻璃丝编织浸渍外套也用F代号表示。

Results 22 patients underwent zygoma reduction and subperiosteal rhytidectomy by coronal incision approaching. 5 cases with frontal region depression were filled with ePTEF or a piece of epicranial aponeurosis. The follow-up time was 6～24 months. All the patients were satisfied with the final results.

结果：本组22例患者，均行头皮冠状切口颧骨颧弓复合体缩小及骨膜下除皱术，部分患者以膨体聚四氟乙烯补片或帽状腱膜行中上面部凹陷填充，术后面部软组织及骨性结构均得到显著的年轻化改善效果，随访6～24个月，面部外观满意。

BACKGROUND: The chief domestic alloplastic material implantation used in augmentation rhinoplasty is silicone rubber. Other materials used are porous highdensity polyethylene and expanded polytetrafluoroethylene (e-PTFE, Gore-Tex).

背景：加高型鼻整形手术中使用的人工合成异体填充物在国内主要以矽胶为主，其它还有膨体聚四氟乙烯(expanded polytetrafluoroethylene， e-PTFE， Gore-Tex)和多孔高密度聚乙烯(porous high-density polyethylene， PHDPE)等。

Produced biaxially oriented PTFE Microporous PTFE films in the leading domestic level.

所生产的聚四氟乙烯PTFE双向拉伸微孔薄膜处于国内领先水平。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
