tetroxide n.【化學】四氧化物。

tetryl

Thus , such phenomena as vermilion turning black , aging of red lead and the fading of arsenic can now be more essentially represented by the chemical reactions of cinnabar having its crystal lattice transformed , lead tetroxide turned into lead dioxide , and arsenic sulfide turned into arsenic oxide 于是,朱砂變黑,鉛丹老化,石黃退色等現象,便可以用硫化汞轉變了晶格,四氧化三鉛變成了二氧化鉛,硫化砷變成了氧化砷來更本質地加以表述了。

Some key points are resolved with advanced software design conception and technology , and a nitrogen tetroxide concentration monitor with sound and light alarm is developed 通過采用先進的軟件設計思想與技術,解決了幾個關鍵問題,成功地研制出了具有聲光報警功能的高性能四氧化二氮毒氣濃度監測儀。
