The membrane that can withstand such force is made of polyester , polysulfone and polyamide and is held within the white steel cylinders .

能够抵挡这股压力的膜是用聚酯、聚砜和聚酰胺作的，并且固着在白色钢桶之内。

His composite membrane consisted of a very thin layer of polyamide , to perform the separation , and a sturdy support beneath it .

他发明的复合薄膜包含一层很薄的聚酰胺，起隔离作用，其下方还包含一个稳固支撑结构。

Nylon ( polyamide ) and dyneema / spectra ( polyethylene ) are two synthetic raw materials with distinct strengths and weaknesses used in the manufacture of slings and quickdraws .

nylon（聚酰胺）和dyneema/spectra（聚乙烯）是两种用于制造扁带和快挂的合成材料，二者在强度和缺点上存在较大差异。

The supermarket says the technology is split into three main areas , and makes use of fabric comprised of 85 per cent polyamide ( a type of nylon ) and 15 per cent elastane ( the generic non-brand name for lycra ) that compresses flabby areas .

超市称这种技术依靠含85%聚酰胺（尼龙的一种），15%氨纶（就是我们常说的莱卡）成分的面料----来紧实身体松弛的区域，并且能够在三个不同的位置起作用。
