the target compounds synthesized to synthesize a series after 4 - instead of aniline - 6 -(2 - hydroxyl replace c oxygen radicals) quinazoline compounds has laid a good foundation.

目标化合物的顺利合成为以后合成一系列4-取代苯胺-6-(2-羟基取代丙氧基)喹唑啉类化合物奠定了良好的基础。

The goal of the successful synthesis of compounds for the subsequent synthesis of a series of 4 - to replace the aniline -6 -(2 - hydroxy replace C oxy) quinazoline compounds laid a good foundation.

目标化合物的顺利合成为以后合成一系列4-取代苯胺-6-(2-羟基取代丙氧基)喹唑啉类化合物奠定了良好的基础。

On the other hand, a new quinol, 3,5-dimethoxy-4-acetonyl-p-quinol together with sixteen known compounds were also isolated from the aerial part of this plant.

另外，从其地上部也分离出一种新化合物命名为3，5-dimethoxy-4-acetonyl-p-quinol及16种已知化合物。

The 2/SegPhos/I2 system can be applied in asymmetric hydrosilylation of quinoline and quinoxaline derivatives successfully, and up to 93% ee was obtained.

芳香杂环化合物喹啉衍生物的不对称硅氢化反应一直是不对称氢化领域的一个难点，我们利用2/-SegPhos/I2催化体系首次实现了杂芳香化合物：喹啉和喹喔啉的不对称硅氢化反应，最高获得了93%的ee值。

Separation of enantiomer for the acidic racemate could be improved with a lower pH value of the mobile phase since the dissociation of acidic compound was impressed, but it did not affect significantly the resolution of neutral compounds.

在流动相中使用低pH值，能有效抑制酸性化合物的解离，从而显著增强其手性识别能力；对于中性化合物，流动相中pH对手性分离影响不大。

For instance, a compound can be synthesized with one of the atoms replaced by a radioactive isotope of the element.

例如，用某种放射性元素来代替原来的元素合成某一化合物，则放射性就可追踪这一化合物的合成过程。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
