HPLC plays an important role in modern life, covering research, everyday inspection, industry, etc..With the development of the society, fast analysis is demanding.One of the challenges in HPLC is how to enhance mass transport efficiency.The key to it is to develop the desired stationary phase material, which has suitable properties.Perfusive polymeric materials were put forward to afford fast mass transfer; however, polymer has its own defects of low mechanical strength, week resistance to organic solvent and temperature.Furthermore, monolithic materials were proposed as the stationary phase of HPLC for fast separation; its limitation lies in the difficulty of fabrication, packing, etc.In a long time, such development is retarded.In our continuous effort, perfusive silica microspheres were put forward.They were formed by the synergetic interaction of sol-gel transition and phase separation in confined emulsion droplets.After suitable post-treatment, such as calcination at high temperature, silica microspheres with high mechanical strength were obtained.

杨慎：房地产业仍是政府参与的 行政主导性行业我对当前房地产业整体状况的判断是：第一，投资过快不过热。不存在总体上供大于求而形成的整体过热。现在消费者对住房的需求，是摆在居民各类消费前三位的需求。第二，房价降幅不降价。现在房价要解决的问题是降幅而不是降价。房价取决于供需关系。需求普遍在增长，但土地紧缩、银行贷款紧缩导致供给减少，价格必然上涨。第三，现在的房屋标准偏低不偏高。总体来讲，不是建得好
