The annulation of stilbene compounds were studied. Phenanthrene derivates-interme diates of tylophorine were synthesized by annulation from-2,3-bis(3,4-dimethoxyphen yl)acrylic acid and-2,3-bis(3,4-dimethoxyphenyl) acrylonitrile with phenyliodine diace tate as a friendly and high efficient catalyzer.The route was first reported, whose application foreground would be promising.The catalyzer will be used to study of synthesi- zing a series of new phenanthrenes.

For example, H, atomic weight of 100,794 hydrogen, carbon FC atomic weight of 1201, the atomic weight of oxygen O for 1594, Copper Cu for F63546 and so on. F history, had also used the other two kinds of "benchmarks", and there have been two kinds of scales used in parallel .1803 years, J Dalton published the first atomic table, the hydrogen-quality of the original F son as a "benchmark "requiring H, atomic weight is 1. In 1826, JJ Berzelius Tony F are presented to the quality of 116 oxygen atoms O as a" baseline "(scheduled for O, E atomic weight 16), which is has been in use to 1961 "Oxygen unit." 1929, found that the oxygen in nature, in addition to the greatest abundance of 16O, there are a small amount of slightly heavier 17O and 18O two kinds of isotopes, and the different sources of oxygen, its composition is slightly different.

例如氢H的原子量为100794，碳FC的原子量为1201，氧O的原子量为1594，铜Cu为F63546等。F历史上，还曾用过另外两种"基准"，并且有过两种标度并行使用。1803年，J道尔顿发表的第一张原子量表，把氢原F子的质量作为"基准"，规定H的原子量为1.1826年，JJ贝F采利乌斯提出，以氧原子O质量的116作为"基准"（定O的E原子量为16），这就是一直沿用到1961年的"氧单位"。1929年发现，自然界中的氧，除丰度最大的16O以外，还有少量稍重的17O和18O两种同位素，并且不同来源的氧，其组成也稍有不同。

Based on the study of gas solid flow field in blowpipe of BF with oygen enriched PCI, the oxygen and coal concentration distribution inside the blowpipe were simulated and discussed, including the influence of position and inserting angle of the oxygen coal lance, the pattern of the oxygen enriched jet, as well as grain size of the coal.

在对高炉局部富氧喷煤直吹管内气固两相流流场研究的基础上，对直吹管内氧和煤粉的浓度场进行了数值研究，包括氧-煤喷枪的插入角度和枪位、局部富氧射流的漩流数以及煤粉粒度的影响。

The rotational jet and local oxygen enrichment can improve the mixing of oxygen and pulverized coal, but the effect of coal injection is weak on the whole flow field in blowpipe. The mass and momentum transfer near the exit of lance are very strong.

结果表明，氧-煤喷枪的漩流、富氧率等仅在氧枪出口的有限区域内对流场有较大的影响；喷煤对整个直吹管内的流场影响较小，但在氧-煤喷枪出口附近区域会促使气相和煤粉激烈混合，动量和质量传输较强烈。
