Traditionally , mordants were found in nature 按照传统的方法，腐蚀剂从自然中提取。
3.
But chemical mordants such as alum are popular today 但化学腐蚀剂如明矾今天已经十分普遍。
4.
It is a corrosive which eats away unity , undermines cohesion , causes apathy and creates dissension 它是一种腐蚀剂，使团结涣散，关系松懈，工作消极，意见分歧。
5.
Corrosion of metals ; testing and assessment of the corrosion protection of coated metallic materials in contact with aqueous corrosive agents 金属腐蚀.对与含水腐蚀剂接触的涂层金属材料防腐检验
6.
This etchant can show different defects , such as dislocations , grain boundaries , twins , te - rich inclusions and precipitates etc . , on different planes 这种腐蚀剂能显示不同晶面上的多种缺陷，如位错、晶界、富te相等。
7.
To help fight corrosion , meguiar ' s can include anti - corrosion agents , which dramatically help to protect the surface from corrosive attack and deterioration 为了防止腐蚀，美光有自动抗腐蚀剂，它可以帮你奇迹般的保护受侵蚀和变质的船体。

Bodily injuries resulting from dry heat generated by flames , electric current , hot objects , radiation , over - exposure to sun rays chemical corrosives , etc 烧伤：指因火焰电流炽热物品辐射曝晒化学腐蚀剂等产生的乾热，对身体造成的伤害。
9.
Comparing the results which were obtained when the reagent and temperature and time varied , we found the dislocation was displayed very clearly and accurately when we etch with koh at 290 for fifteen minutes , which was the best condition 进行了不同温度、不同的试剂以及不同的腐蚀时间条件下的缺陷显示实验。发现，用熔融的koh腐蚀剂在290下腐蚀15分钟时，显示的位错最为清晰、准确，效果最佳。
