不透气性的

AIM:To investigate the clinical effects and safety of rigid gas-permeable contact lensesin the treatment of ametropia.

目的：观察硬性透气性角膜接触镜矫治屈光不正的效果、使用安全程度及舒适度。

It is warm, gentle, and easy close-fitting hygroscopicity, good air permeability, won't produce electricity.

它的优点是轻松保暖，柔和贴身、吸湿性、透气性好、不会产生静电。

Not only it has the excellent properties of solvent-borne polyurethane with good low temperature resistance, great adhesion, as well as outstanding toughness combined with good flexibility, but also advantages of innocuity, incombustibility, low odor, environmental friendliness, energy conservation, security, convenient operation processing, and good film-forming breat...

它不仅具有溶剂型聚氨酯耐低温、柔韧性好、粘接强度大的优良性能，还具有无毒、不燃、气味小、不污染环境、节约能源、安全、加工方便、成膜透气性好等优点。

All these characteristics enable the cushions to promote blood flow, to keep health, to protect from cervical syndrome, and to lower the probability of miliaria and dermatosis.

精选的竹炭汽车座垫，具备透气性、吸湿、排湿、抑制细菌、不粘身、释放远红外线等独特优点，以达到活血、保健、防治颈椎疾病之功效，减少汗疹、皮肤病等发生机率。

I plant the production of wall putty powder with strong adhesion, water-resistant performance, the construction is simple, not from powder, not crack, good ductility, breathable and strong, non-toxic tasteless, storage, transportation convenient, can save 30% topcoat.

我厂生产的外墙腻子粉具有附着力强、耐水性能好、施工简便，不脱粉、不开裂、延展性好、透气性强、无毒无味、存储运输方便，还可节省30%左右的面漆。

But the disadvatages are not good to wearing resistance,heat resistance,moisture pickup,and breathy, and easy to out of shape, to having statis, is could make any kind of cloth, but level is not going to become higher so that could go up better place..

它们的缺点则是耐磨性、耐热性、吸湿性、透气性较差，遇热容易变形，容易产生静电。它虽可用以制作各类服装，但总体档次不高，难登大雅之堂。

The results show that the vertical sintering speed changes notably with the proceeding of sintering process. After ignition and thermal retardation the bed permeability deteriorates and the sintering speed decreases notably because of the progress of physical chemistry reaction, formation and broaden of combustion zone, and formation of overwet zone. In about 25 min, the over wet zone vanishes, so the bed permeability meliorates and the speed arises rapidly.

结果表明：垂直烧结速度并非固定不变，而是随着烧结过程的逐步进行发生显著变化；点火保温后，随烧结物理化学反应的进行，燃烧带逐渐形成并变宽且产生过湿现象，导致料层的透气性显著变差，烧结速度显著下降，直至约25 min后过湿层完全消失，透气性变好，烧结速度迅速上升。

The results indicate that the recycling of refining slag within 3 times will not cause adverse effects on the desulphurization of the refining slag and the permeability of the ladle,and will not cause resilicon and rephosphorization in steel.

结果表明，精炼渣循环3次以内，不会影响炉渣脱硫及钢包透气性，而且不会造成钢水的回硅、回磷。

It will not influence the air conductivity of the stone and will not change the natural color and luster of the stone.

长时间使用，保护石材不受损坏，不影响石材的透气性，不改变石材的天然色泽。

It will not influence the air conductivity of the stone and will not change the natural color and luster of the stone. Just a regular and simple maintenance will keep the stone as bright as new for a long period of time.

长时间使用，不会造成石材任何损坏，不影响石材透气性及不改变石材天然色泽，定期只需作简单的护理即可保持石材长期亮丽如新。
