Polybutadienes, epoxy resins, and similar polymers may be used while they are in the viscous or liquid state of prepolymerization . 聚丁二烯，环氧树脂及类似聚合物在粘性状或液体预聚态都是可用的。
Since fulvenes show no evidence of ring currents, the chemical shifts of the protons will be found in the normal definite region . 既然富烯不显示环电流存在的迹象，所以质子的化学位移仍然发生在正常的链烯区。
To illustrate some of the features of the equilibrium phenomenon, let us look at the reaction in which cyclobutene is isomerized to 1.3-butadiene . 为了说明平衡现象，让我们看一下环丁烯异构成13一丁二烯的反应。
Small amounts of geographic variation have been demonstrated in several other traits, such as cortical concentration of certain monoterpene . 在其他几个性状上，亦经证明有少量地理变异，诸如皮部的某些单萜烯浓度。
The dichroic agent is polymetric iodine formed by impregnating an initially transparent plastic sheet of polyvinyl alcohol with iodine and heating . 其二向色剂是聚合磺，它是将透明的聚己烯醇塑料薄片在磺内浸渍后加热制成的。
The process provides a facile way of producing hydrocarbl perchlorate from alkenes, cycloalkenes, aralkenes, alkanols, cycloakanols and aralkanols . 本文介绍了从链烯、环烯、芳链烯、链烷醇、环烷醇、芳烷醇来制备过氯酸烃基酯的方便方法。
The meso carbon atom of the methine linkage of the dye is attached to the nitrogen atom of a group which forms an enamine with the methine linkage of the dye . 该染料甲川链上的碳原子与氨基的氮原子相连，而该氮原子又与染料的甲川链形成烯胺。
Fog in such supersensitized emulsions, which are prone to enamine dye-produced fog, can be reduced by employing an azaindene in the emulsion . 这些超增感乳剂中的灰雾，可能是由形成的烯胺染料引起的，并且这种灰雾，可采用向乳剂中加入氮茚来降低。
The process provides a facile way of producing hydrocarbyl perchlorates, from alkenes, cycloalkenes, aralkenes, alkanols, cycloalknols and aralkanols . 本工艺程序提供了从链烯、环烯、芳链烯、链烷醇、环烷醇、芳烷醇来制备过氯酸烃基酯的方便方法。
We see the symmetry we have attributed to allylic particles on the basis of the resonance theory; the two ends of each of these molecules are equivalent . 我们看到了曾经根据共振论而归因于烯丙基型粒子的对称性，所有这些分子中每个分子的两端都是等性的。
