This is done to reduce the current emissions and is seen as a logical replacement for Methyl Tertiary Butyl Ether which, as an oxygenate, improves combustion in petrol engines and allows fuel to burn cleaner.

这是为了减少目前的尾气排放，并被视为是甲基叔丁基醚合理的替代物，MTBE是一种氧化剂，能够改善汽油机的燃烧并使燃料燃烧更清洁。

The electric conductivity of solid polyiodides increases largely as the aggrandizement of polyiodide anions"polymerization degree. The solid polyiodides have excellent sterilizing effects and the effect of tetra-n-butyl ammonium undecaiodide is the best of them, and the sterilizing effects increase as the aggrandizement of polyiodide anions" polymerization degree. The sterilizing effects of resinic polyiodides increase as the aggrandizement of polyiodide anions polymerization degree, the heptaiodide resinic polyiodide has better sterilizing effects than the triiodide and pentaiodide.
