第三章：首先介绍了α-羟基环氧化合物的反应，其次介绍了一个新的金催化的含碳环骨架的α-羟基环氧化合物开环反应，总结了反应规律，提出了可能的反应机理。

In hardness and high hardness wear resistant ring expansion ring expansion.

中硬度耐磨胀圈和高硬度耐磨胀圈。

Ring expansion reactions are important tools in organic synthesis which take advantage of existing ring structures and avoid the unfavorable factors associated with other approaches in the construction of medium and large rings.

自由基成环和扩环反应是有机化学中的重要反应，它可以利用已有环的结构来构筑所需要的中环和大环，避免其他一些不利的竞争反应。

At the same time, line up buyers of real estate are quietly changing, showing the past, inner ring, in the Link as the central axial expansion of the outer ring of regional trends.

Double row tapered hole cylindrical roller bearings with inner ring and shaft are tapered 1:12, bearing lock nut with a round led a bearing in the axial displacement of the inner ring bearings and expansion, to reduce or eliminate Bearing radial clearance purposes.

圆锥孔双列圆柱滚子轴承的内圈和配合轴径均为1：12圆锥，用圆螺母锁紧轴承则使轴承在轴向产生一个位移并使轴承的内圈膨胀，从而达到减少或消除轴承径向游隙的目的。

Enynes with an aryl ring at the alkyne give 2,3,9,9a-tetrahydro-1H-cyclopentanaphthalenes by a 5-exo-dig cyclization followed by a Friedel-Crafts-type ring expansion.

带有芳环的1，6-二烯体和炔作用，并通过5-exo-dig路径环化，再紧接着Friedel-Crafts扩环，可以得到2，3，9，9a-四羟基-1H-环戊二烯并萘。6-endo-dig途径的环化在一些例子中作为副反应被观察到，尽管，这在一些具体的反应中，是作为主反应出现的。

These results show that the ring expansion of cyclopropylsilylene C3H5SiH to silacyclobutene is easy to occur with a barrier of 113.4kJ/mol, while the 1,2-H shift is not competitive to the ring expansion for its much higher barrier.

结果表明，环丙基硅烯经过113.4kJ/mol的势垒扩环重排为硅杂环丁烯为自发反应；而其1，2-氢迁移重排反应热垒为190.0kJ/mol，是非自发反应，难于进行，不能与扩环重排相竞争。
