In addition to reducing the directly emitted ozone and its associated impacts, the regulation will reduce the likelihood of particle and formaldehyde formation when limonene or other terpenes are present indoors.

除了减少臭氧的直接排放和与之相关的影响外，这一条例还将减少室内存在柠檬烯和其它萜烯时颗粒物和甲醛形成的机会。

The reductive hydrogenation of sterols is stronger downward with the depth,and that is much stronger in Site 8 than in Site 17 due to the different sedimentary circumstances.

随着沉积深度的增加，甾烯醇的加氢还原作用越强，且由于两个站位不同的沉积环境，8站位甾烯醇的加氢还原作用更强。

RESULTS: Expression of iNOS proteins was seen on day 1 following the control stent implanting, developed on day 3, peaked on day 10 and lasted till day 28. iNOS expressions at all time points in diallyl trisulfide coated stent group were higher than those in control stent group. Compared with normal blood vessel tissue, the NO production after stenting decreased on day 1, increased on day 3, maximized on day 10, went down to its pre????stenting level on day 28. At all time points, NO levels in allitridi????stented sites were higher than those in control????

结果： 对照支架组术后1 d血管壁中有少量iNOS蛋白表达，3 d表达增加，10 d达高峰，28 d时仍有表达，二烯丙基三硫化物涂层支架组iNOS蛋白在各时间点的表达量均高于对照支架组；对照支架组术后1 d时NO生成量低于正常组织，3 d时NO水平升高，10 d时最高，28 d时降至基线水平，二烯丙基三硫化物涂层支架组各时间点的NO水平明显高于对照支架组。
