Comparing with the result of methyl iodide in intense laser field, some differences are observed:(1) at the same laser field intensity, the highest charged fragment ion of methyl bromide was Br(superscript 3+), lower than I(superscript 6+) of methyl iodide;(2) the dehydrogenation channel was observed in the multiphoton dissociation or Coulomb explosion of methyl bromide, but was not observed in the case of methyl iodide;(3) HBr(superscript +) was observed, but there was no similar channel in the case of methyl iodide;(4) for methyl bromide, the valid charge distance of Coulomb explosion increases with the product of p and q; while in the case of methyl iodide, the distance remained almost the same;(5) the producing channel of CH(superscript + subscript m)(m=0, 1, 2) is different from the ionization-dissociation of methyl iodide in which the stepwise dissociation of CH3(superscript +) was thought to be the main channel, CH(superscript + subscript m)(m=0, 1, 2) of methyl bromide are mainly from the products of the direct dissociation of the dehydrogenated parent ions instead of the stepwise dissociation of CH3(superscript +).

与碘甲烷在强场中的实验结果对比发现：(1)在相同的激光场强下，碘甲烷电离解离的最高价碎片离子为I(上标 6+)而溴甲烷为Br(上标 3+)；(2)溴甲烷质谱中存在母体离子的脱氢产物CHBr和CHBr(上标 2+)，而对于碘甲烷，没有检测到这些通道，C-I键首先断开；(3)质谱中存在H^79Br和H^81Br，而碘甲烷的电离解离中不存在HI产物；(4)溴甲烷库仑两体爆炸的有效电荷间距随着两碎片电荷乘积的增大而增大，而对于碘甲烷此间距几乎不随电荷乘积变化；(5)CH(m=0， 1， 2)的主要生成通道可能与碘甲烷不同，不是来自CH3的顺序脱氢，而是来自脱氢母体离子的直接解离。

Wo hydrogen-adsorped peaks of TPR, namely α and β peaks, which can be ascribed to Mo(superscript 6+)→Mo(superscript 5+) and Mo(superscript 5+)→Mo(superscript n+)(n=4, 3, 2) reduction processes respectively, appear both at sulfured state and functioning state. The experiment results indicate that there is a close relation between the altitude of the peaks and the activity of the catalyst at low temperature.

Methods The pyrogllol auto-oxidation was adopted to produce superoxide anion O(superscript - subscript 2; the system H2O2/Fe(superscript 2+) was used to produce hydroxy radical through Fenton reaction; and spectrophotometry was used to detect the clearing functions of drugs with different concentrations against O(superscript - subscript 2) and OH.

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.

When pH is 8.0, the flocculation rate can reach 91%. The experiment indicates that the evaluation system of kaoline is affected by PO(superscript 3- subscript 4) and Ca(superscript 2+) when the concentration of PO(superscript 3- subscript 4) is high in the substrate. As the real flocculation efficiency cannot be achieved, the evaluation system needs to be modified.

实验表明，培养基中PO(上标 3-下标 4)浓度较高时，现有的微生物絮凝剂高岭土评价体系会受到PO(上标 3-下标 4)与Ca(上标 2+)的影响，不能真实地表示微生物絮凝剂的絮凝效果，需要对现有评价体系进行修改。

Templating agent could not be sufficiently removed at temperature below 500℃, while temperature exceeding 600℃ might result in collapse of the framework. The conversion from Co(superscript 2+) to Co(superscript 2+) was a gradual time-consuming process. Calcination at 550℃ in a muffle furnace for 10 hours could remove the templating agent and bond water and give a satisfactory result.

焙烧温度和时间决定CoAPO-5分子筛最终的物化性能，焙烧温度低于500℃不能有效去除模板剂，而高于600℃将导致分子筛骨架的破坏，Co(上标 2+)向Co(上标 3+)转化是一个逐渐转化的过程，550℃下焙烧10h，能较好地去除模板剂和结合水及实现Co(上标 2+)的转化。
