阻挡物

海啸更准确地被描述成“水墙”，能将任何阻挡物夷为平地。

Tsunamis are more accurately described as these " walls of water " that push onto shore and plow through anything they hit .

随着气流经过层状纤维，呼吸防护罩会以多种方式阻挡颗粒物。

The respirators block particles in a number of ways as the airflow encounters layered fibers .

香港大学公共卫生学副教授高本恩（BenjaminCowling）在电子邮件中表示，这种口罩的设计用途是防止血液飞溅之类的问题，而不是阻挡细颗粒物。

But these are designed to prevent problems like splattering blood , not to block tiny particles , Benjamin Cowling , an associate professor of public health at the University of Hong Kong , said in an email .

另一个问题是，尽管N95防护罩能阻挡细颗粒物，它们却无法抵御另一种与交通有关的污染：像氮氧化物这样的气体或挥发性有机化合物。

Another issue is that while N95 respirators guard against small particles , they do not combat another form of traffic-related pollution : gases like nitrogen oxides or volatile organic compounds .

不过，能阻挡细颗粒物的呼吸防护罩可能会让呼吸变得更困难。

But respirators that guard against small particles can make it more challenging to breathe .

防护特性在于：它减小了腐蚀介质在电极表面的集聚，阻挡了反应物和腐蚀产物的传输，增加了回路电阻，表面缺陷率是决定处理后耐蚀性的重要因素。

Protective character depends on : it reduced the corrosive medium in the electrode surface of the cluster , blocking the reactant and corrosion product transmission , increased the loop resistance , the surface defects is decided after the corrosion resistance of handling important factors .

这些砂洲的生长仅限于波浪能冲进的深度，并且阻挡了外边砂质物的进入。

The growth of these bars is limited by the depth at which waves will plunge and prevent further sand encroachment .
