将金属表面的这些污物去除并提供氧化的环境后，就形成了钝化膜并实现了钝化作用。
By removing these soils from the metal surface and providing an oxidizing atmosphere, the passive film is allowed to form and the passivation is accomplished.
钝化过程（在3.1.1.2说明）在没有进一步的化学处理情况下也会发生，但钝化作用将会被“后清洗处理”（在3.1.1.3说明）提高增强。
The passivation process defined in 3.1.1.2 will occur without further chemical treatment, but may be augmented and improved by the post-cleaning treatments defined in 3.1.1.3.
用植物源抗病毒制剂VA与烟草花叶病毒（TMV）混合，经枯斑半叶法接种，结果证明，VA对TMV有较强的体外钝化作用，体外钝化后的枯斑抑制率为80 .0 % ；
VA , a anti viral agent from plants, could inactivate TMV in vitro , when it was mixed with TMV and inoculated by means of half leaf. The inhibition rate of necrotic local lesions was 80.0%.
