Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a"和4a"也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。

公司主导产品为医药中间体对甲基苯酚、食品添加剂山梨酸和山梨酸钾等。目前，公司年产对甲基苯酚8000吨，山梨酸和山梨酸钾25000吨，产品在占领国内市场的同时，远销欧、美、日、韩等国家和地区，出口量占销售总量的60%以上，成为德州市重要的出口创汇型企业，并成为全球对甲基苯酚生产的重要基地和国内山梨酸和山梨酸钾重要的生产基地。

Test and analysis show that, the distribution patterns of the tangent veloctiy fields in the big cone area and the small cone area, which are comprised of para-free vortex and para-forced vortex, are basically identical without a change of the radius of the boundary surface; with the increase of the angle of the small cone, the para-free vortex area decreases and the para-forced vortex area increases, and the emulsifiability of the fluid drips increases with the increase of velocity gradient; the tangent velocity increases with the increase of inlet flow, and the maximum tangent velocities of both the big cone area and the small cone area are 4.94 times of the inlet flow; and the maximum tangent velocity increases with the increase of the split ratio and with the radius of the boundary surface not changed.

试验分析表明，大锥段和小锥段切向速度分布规律基本相同，均由准自由涡和准强制涡构成，分界面半径rm没有变化；随着小锥角θ的增加，准自由涡区缩小，准强制涡区扩大，速度梯度增加会加大液滴的乳化程度；随入口流量增加，切向速度增大，经拟合得出大锥段和小锥段的最大切向速度均为入口流量的4.94倍；分流比加大，分界面半径基本不变，最大切向速度增加。

The leucogranites veins occurred widespreadly in the para-metamorphic rocks, in which the hypersthene melagranulite distributed. That suggests the source rocks of leucogranites of the High Himalaya are para-metamorphic rocks. For the basement was uplifting, pressure relieved and lacked water, source rocks were melting partly and formed the leucogranite magma.

基底副变质岩中广泛分布淡色花岗岩脉体，在基底副变质岩中的淡色花岗岩脉体中发现紫苏辉石暗色麻粒岩残留体，这表明本区高喜马拉雅淡色花岗岩源岩为基底副变质岩，且基底副变质岩是在基底快速隆升降压的条件下发生缺水熔融生成的淡色花岗岩岩浆。

In experimental research, the S-L-E of three groups of isomers was determined by using differential scanning calorimetry , and more than two hundred reliable data were obtained. The isomers include meta-, ortho-, and paradichlorobenzene, meta-, ortho-, and para-dibromobenzene and meta-, ortho-, and para-nitro-benzoic acid.

在实验的研究中，采用差式扫描量热测定了邻、间、对二氯苯，邻、间、对二溴苯及邻、间、对硝基苯甲酸等三组同分异构体物系的固液相平衡关系，共得到二百多个可靠的数据。

OrthoSubstituted phenols gave the para-para-coupling products and para-substituted phenols gave the ortho-ortho-coupling ones, while hindered phenol gave the corresponding oxidative coupling product.

该氧化偶联反应的反应条件温和、产物易于分离、收率高，可作为有机合成中某些碳-碳键形成的新方法加以应用。

On late nightTV, for example, young pop stars try out the Para Para; Even Tokyo Disneyland has succumbed to the craze In its revues, Disney characters and stage performers break into the Para Para when The Mickey Mouse March is played.

比如在晚间电视节目中，年轻的流行歌星们试着跳起了啪啦啪啦舞；连东京的迪斯尼乐园也被卷入热潮中：在迪斯尼乐园上演的滑稽剧里，当&米老鼠游行曲&奏响时，迪斯尼人物及舞台表演者们就会跳起啪啦啪啦舞。
