Ray florets elongated faster than disc florets from phase P3, when tetrads of haploid microspores appeared, and the pigmentation of the ray floret began when the pollen grains showed germination apertures in the disc florets of the first whorl. The effects of light, sugar and GA3 on flower growth and development were investigated in vitro. Inflorescences in the P2 phase or later could grow and bloom in vitro, and sucrose, GA3 and light promoted flowering.

研究表明，分化完全的舌状花在P3期、即花粉细胞四分体出现之后长度超过盘状花，在盘状花的雄蕊出现具有萌发孔的花粉粒之后，舌状花开始着色。P2以后的花序经离体培养可以开放，光、糖和GA3对花序的生长和开放有显著的促进作用。

This plate of spice spaghetti, you can find it everywhere in italy, and this little package of mixing spices is easy to buy as well. The spices inside are: dry garlic, dry chilly pepper, dry black pepper, and a lot of parsley. They are simple but after you fry them together with the oil they'd become amazingly tasteful.

这道香料面在义大利各处都吃的到，像这样的混何香料包到处也都买的到，里面的内容物很简单：乾大蒜，乾辣椒，胡椒，和大量的 xyz软体王巴西利(洋香菜，现在顶好超市都买的到)，以上这四样简单的东西混合之后用油爆香出来的美味是无与伦比的！

Quantitative analysis of the EXAFS spectra showed that the microscopic structure of Znon anatase TiO2 is four coordinate complex, and there are at least two types of bonding based on the average Ti-Zn distances in the second sphere. Two different geometry configurations of single-corner and double-corner for adsorption on the (101) surface cluster were calculated using DFT method.

EXAFS结果表明，Zn在吸附时由自由水合状态下的Zn-O六配位八面体结构向四配位四面体结构转化，中心Zn原子的第二配位层存在两种不同的Zn-Ti距离（R1=0.371和R2=0.332nm）。

In the coming 2～3 years, there are four aspects for improvement in thin slab casting and rolling in China:(1) production of high quality products and further processed products by whole line of thin slab casting－rolling, cold rolling and coating;(2) reaching a higher productivity level with advantages of thin gauge hot rolled products;(3) leading the technology innovation in the field of mold modification, dynamic soft reduction, ferrite rolling and semi－endless rolling etc.

未来两年中，中国薄板坯连铸连轧技术创新的重点应有四个方面，即：全面贯通薄板坯连铸－热连轧－冷连轧－涂镀层产品作业线，生产高质量产品与深加工产品；在发挥薄规格热轧产品优势的基础上再创高效率生产新水平；努力在优化薄板坯连铸结晶器、动态轻压下、铁素体轧制、半无头轧制等工艺开发方面走在前列；工艺技术、装备、相关材料基本自主开发。

In order to study the reasons and preventive measures of dynamic disasters such as shock bump and the destroy of rock mass in mining engineering resulted from the outburst of mash gas and coal during mining,stress-relieving measurement and temperature and confining pressure calibration were made with improved CSIRO cells at 4 measurement points in Datong mining area .
