It is this very deduction which makes the generally accepted prediction regarding the " clock paradox " unacceptable to Dingle, but which has led both Ives and Builder to consider interpretations of special relativity in which an ether plays an important role, at least from the philosophical point of view.

正是这种非常扣除使得普遍预测的"时钟悖论"不可接受dingle，但已导致双方艾夫斯和建设者考虑诠释狭义相对论一个以太起着重要的作用，至少从哲学的角度来看。

The solubilities of ROK in several different solvents such as toluene, ether, THF and 2G were studied. Considering the influence of solvent on the microstructure of telomers, THF was determined to be the best solvent.In the system of n-BuLi/ROK/xylene/2G/olefin, the influence of ROK on diolefin anionic telomerization was investigated, and the result shows that the difference between butadiene system and isoprene system was little.
