In order to analyze the thermal cracking products of fuels, we set up a GC analytical system. The gas products, which comprise methane, ethane, ethylene, propane, propylene and other gases, were collected and analyzed by gas chromatography provided with a flame ionization detector . We calculate the theoretical heat sink of n-heptane at the temperature of 600℃ and 800℃. The theoretical heat sink calculation of iso-octane at 700℃ is also related.

K shell ionization cross sections of Ti and V elements from the measured result of K α X rays using the spectrometer are derived.

电子碰撞引起原子内壳层电子电离截面的研究是现代原子分子物理的基本问题之一，也一直是实验和理论工作者关注的课题。

The coronal green line, for example, came from the 'forbidden line' of iron-14, written , iron stripped of 13 of its 26 electrons (neutral iron is Fe I, so the Roman numerals exceed the ionization number by 1), which would require such a high temperature that the corona must be at millions of kelvins.

例如日冕谱线中那条绿线，来自铁-14

The morphology of dispersive emulsion particle was observed by SEM.The results showed that the moderate amount of surface carboxyl groups and ionization carboxyl were available to the improvement of water resistance of latexes.

SEM结果表明羧酸改性后的乳液微观分散状态良好，适度的表面羧基密度和适量的离子化羧基对提高乳液的湿强度是有效的。

The mechanism of dioxygen oxidation of NTS to DNS in alkali solution under mild condition was inquired into. The result showed that the key step in the preparation of DNS from NTS was the formation of 4-nitro-2-sulfobenzyl anion as a result ionization of NTS in strong alkali and then oxidization to 4-nitro-2sulfobenzyl radical by activated dioxygen.

探讨了在温和条件下于碱的水溶液中氧气液相氧化4-硝基甲苯-2-磺酸制取4，4'-二硝基二苯乙烯-2，2'-二磺酸的反应机理，发现4-硝基甲苯-2-磺酸在碱作用下发生离子化生成4-硝基-2-磺酸基苄基阴离子，然后被活化的分子氧氧化成4-硝基-2-磺酸基苄基自由基是反应的关键步骤。
