阻隔

When designing multi-layer packaging, barrier protection may be provided from layers in addition to the barrier layer.

设计多层包装材料的时候，材料的阻隔保护功能不仅来自阻隔材料层本身，还可能同时来自其他的几层材料。

The different molar ratio of hexane diacid to terephthalic acid with the same molar diamine is designed to give the composites with different viscosity, thermal performance and the barrier properties. The 3-10 times of enhanced barrier properties of these polyerster based nanocomposites with this above MXD6T to pure polyester resins are first reported.

在相同摩尔二胺的情况下，不同摩尔比例的己二酸和对苯二甲酸使复合材料具有不同的粘度、热性能和阻隔性能，含有NMXD6T改性剂的聚酯其阻隔性能相对于纯聚酯提高了3-10倍。

Here, we took demonstration study of the ecological impacts of disconnection from the river on fish recources in Zhangdu Lake. Our results showed that:(1) Fishery mode changed and the rate of wild fishery production changed from 95% in 1949 to less than 5% in 2002.(2) Fish species have decreased from 80 in 1950s to 52 at present, and the rate of migrant and potamic species decreased from 50% in 1950s to 30% at present.

我们以涨渡湖为例开展江湖阻隔后对单个湖泊鱼类资源所产生的生态影响进行研究，结果表明：江湖阻隔导致湖泊生产经营方式改变，使得野生渔业产量的比例由1949年的95%，降低到2002年的不足5%；江湖阻隔后湖泊鱼类种类由50年代约80种下降到现在的52种，其中，洄游性和流水型鱼类比重由50%下降至不足30

我们以涨渡湖为例开展江湖阻隔后对单个湖泊鱼类资源所产生的生态影响进行研究，结果表明：江湖阻隔导致湖泊生产经营方式改变，使得野生渔业产量的比例由1949年的95%，降低到2002年的不足5%；江湖阻隔后湖泊鱼类种类由50年代约80种下降到现在的52种，其中，洄游性和流水型鱼类比重由50%下降至不足30%；迷魂阵渔获物在单位产量、个体大小上极显著(p 0.01)地高于通江湖泊，但在物种数和多样性指数上则要低得多(p 0.01)。

The results showed the masterbatch prepared from EVOH/compatibilizer,HDPE and EVOH/compatibilizer(4:1)was used as barrier masterbatch,the prepared material had an obvious and homogeneous toothlike structure,having good barrier property.

结果表明采用EVOH／相容剂和HDPE、EVOH制备的母粒能明显改变材料的流变性能，当采用EVOH／增容剂为4／1的阻隔母粒，所得材料的结构为大而均匀的片状形态，具有优异的阻隔性。

THE miracles of nature are everywhere : on landing , a beetle folds its wings like an origami master a lotus leaf sheds muddy water as if it were quicksilver a spider spins a web to entrap her prey , but somehow evades entrapment herself .

大自然的神奇无处不在：在陆地上，甲虫能像折纸高手一样将自己的翅膀折叠起来；荷叶能够如阻隔水银一般地阻隔泥水；蜘蛛通过织网既可以捕捉猎物也可以帮助逃脱捕捉。

After removal of a smoking article the gap in the barrier layer is reclosed and released by the repositioning of the adhesive layer, carrying with it the flap of barrier material.

在取出香烟后，使粘结剂层复位就可将阻隔材料的缝隙重新闭合并密封，这可通过阻隔材料的折片来进行。

The window glass which separates us from the scenery outside seems to be thin and invisible, but it has the power of separating everything, doesn't it?

阻隔风景的玻璃看起来薄透无形，可是阻隔了一切不是吗？
