The central ring appears to represent the narrow waist of an hourglass-shaped puff of gas, and the larger rings are the edges of two teardrop-shaped lobes, evidently created by the star a few tens of thousands of years before it exploded.

中央的环看来是沙漏状云气的细腰，而较大的圈圈则明显是在爆炸前数万年，该恒星就已经喷出的两片泪珠状云瓣的边缘。

Stepping motor is a kind of electromechanical component that is driven in step angle or line displacement by electric pulse signal. Because of having the advantage of easy open-loop control and no accumulating error, stepper motor is being applied widely in many fields.

This paper developed an equation of differential pressure and Reynolds' numbers for pipe and annular flow, and presened a method of accurate calculation of rheologic parameters.

本文推导了管流和环空流动的压降公式和雷诺数，提出了精确确定流变参数的计算方法。

In conclusion, the numbers of PAHs rings have great influence on PAHs degradation.

综合以上结果，PAHs的降解随环数增加而减少。

The invention provides a nanometer catalyst for liquid phase oxidation process of cyclohexane, which is characterized in that a silica molecular sieve SBA-15 with meso pore canal is taken as a carrier; one or a plurality of transition metals is/are taken as active component, which is highly dispersed in the carrier, with lower content ranging from 1 percent to 3.5 percent of mass.

一种用于环己烷液相氧化的纳米催化剂，其特征在于：采用具有介孔孔道的全硅分子筛SBA-15为载体，一种或数种过渡金属氧化物为活性组分，活性组分在载体上高度分散，含量较低，范围为1％-3.5％质量。
