查询词典 existed

During mixed fermentation, two peaks existed in production of 2-keto-L-gulonic acid, including 8～20 hours and 24～40 hours; the activity of L-sorbose dehydrase increased rapidly and 2-keto-L-gulonic acid reductase slowly.

在流加糖发酵过程中，2-酮基-L-古龙酸的合成有两个高峰期：8～20小时和24～40小时高峰期。L-山梨糖脱氢酶总酶活迅速上升，2-酮基-L-古龙酸还原酶活性始终呈平缓上升趋势。

These dendritic NOBIN derived Schiff base ligands have been applied to titanium catalyzed hetero-Diels-Alder reaction of Danishefshy's diene and aldehydes, affording the corresponding 2-substituted 2, 3-dihydro-4H-pyran-4-one in quantitative yields and excellent enantioselectivities (up to 97. 2%ee). Comparing the reactivities and enantioselectivities of reaction catalyzed by the titanium complexes of these Schiff base ligands, it was found that a series of ligands L〓 were superior to the other three series of ligands L〓, L〓 and L〓, a significant positive NLE and a dendrimer effect existed in the L〓 dendritic catalyst system. The disposition of the dendritic wedges and the dendron size in the ligands were observed to have a significant impact on the enantioselectivity of the reaction.

NOBIN衍生的树枝状大分子希夫碱手性配体与钛形成的配合物在催化不对称杂Diels-Alder反应中的应用将得到的四个系列NOBIN衍生的树枝状希夫碱三齿手性配体与四异丙氧基钛形成的配合物用于催化Danishefsky's diene与醛的不对称杂Diels-Alder反应，通过反应条件的优化，获得了定量的收率和最高达97.2％ee值的对映选择性；考察了这四个系列NOBIN衍生的树枝状希夫碱钛配合物的催化活性和对映选择性，结果发现它们的活性次序依次为L〓≈L〓＞L〓＞L〓，对映选择性次序依次为L〓＞L〓＞L〓＞L〓。

For a long time,there have existed in China a flexibility in the town planning,a tendency toward decentralization,urban expansion by the aggregation of fixed units,the mobility and prefabrication of buildings,and the use of a precise standard-the 'chien',the basic unit of construction derived from the width of the central beam.

长久以来，在中国存在着一个非常具有弹性的城规，一个分散性地发展趋势，一种由硬件叠加驱使的城市膨胀。由于是大量采用木头的建筑，通过规范的"进"和"间"的基本空间单位，以及精确长度的梁柱等基本结构单位，中国传统建筑有着很大的活动性以及类似于现代建筑的"预制"方法。

There is also another circumstance that contributes not a little to my conviction of the weakness of ancient times. Before the Trojan war there is no indication of any common action in Hellas, nor indeed of the universal prevalence of the name; on the contrary, before the time of Hellen, son of Deucalion, no such appellation existed, but the country went by the names of the different tribes, in particular of the Pelasgian.

此外，有另外一个情况着实使我确信古代时期并不强大，在特洛伊战争之前，在希腊没有任何公共活动的迹象，甚至也没有真正通用的希腊称呼；相反，在Deucalion的儿子，Hellen和他的儿子时代之前，根本没有这个称呼，但是各国却使用不同部落的名称，尤其是在Pelasgian。

This is because such a devise never existed in history or in the history of the English language.

这是因为在历史上从未存在这样或设计史上的英语。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
