碘定量的

Methods IO(superscript - subscript 3) was prepared by quantitative oxidation of bromine water, with the excessive bromine removed with formic acid. In the presence of excessive iodide, I(superscript -) would be oxidized by I(superscript - subscript 3) to form 3 times of I(superscript - subscript 3) in mol, displaying maximal absorption at 286nm in ultraviolet zone and a slightly low apex at 345nm.ε286=1.3×10^5 Lmol^(-1)cm^(-1),ε345=8.1×10^4 Lmol^(-1)cm^(-1), with both showing high sensitivity.

利用溴水定量氧化I生成IO(上标-下标 3)，再用甲酸除去过量的溴，IO(上标-下标 3)在过量碘化物存在下氧化I产生3倍摩尔量的I(上标-下标 3)，在紫外光区的286nm具有最大吸收，并在345nm处另有一略低的吸收峰，ε286=1.3×10^5 Lmol^(-1)cm^(-1)，ε345=8.1×10^4 Lmol^(-1)cm^(-1)，均具有很高的灵敏度。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
