In an age of interactivity, spawned by home computers and video games, and of hybrids, inspired mainly by hip-hop, TV is better able to make adjustments on the hoof, and the frenzied evolution of one genre into another - from, say, a trashy reality show such as Survivor to a stylish drama such as Lost - is dizzyingly fast.

Compared to other models pointed out by foreign scholars, my model was characteristic of multiple periods during evolution of urban systems, complexities of the course of forming urban systems, multiple types of urban functions, periodicity of regional changes of the important regions of urban development, periodicity of dominances of inland central city and seaport gateway city.

此后，随着海疆由开启转为封闭，再由封闭转为开启，最大城市由青岛转为济南，再由济南转为青岛；中心地职能体系由&青岛单中心体系&转换为&青岛、济南双中心体系&，再转换为&青岛单中心体系&；工业发展重点区域也由沿海转向内陆，再由内陆转向沿海；口岸城市的门户职能强度也经历了增强、减弱、增强的不对称&U&型变动；城市体系的空间结构经历了碎化—整合—碎化的过程。

Cellular Senescence is the end of cell proliferation into irreversible G1 growth arrest after certain population doublings, but still maintaining the basic physiological and biochemical activities. It is a kind of cancer-protection mechanism originated from evolution.

细胞衰老是细胞经过一定增殖代数后进入特定G1期生长阻滞，但保持生理生化活性的现象；它是生物进化的结果，也是个体抗癌变的自我保护机制之一。

Careful analysis on NBE can facilitate nowcasting of severe weather events and further understanding of their evolution. After detailed study on three cases concerning with NBE, it is concluded:(1) NBE triggered by fast moving echo in upstream is an important indication of disastrous wind;(2) NBE can develop into severe storm under proper conditions. There are often two stages during this kind of growing: the first is developing of initial echo, the second is snap growing of echo core;(3) Doppler radar reflects outflow of downburst as a nearly ringed NBE. Inside look on downburst can be obtained combining NBE with other data.

文章结合发生在上海的3次强对流天气个例，详细分析了弱窄带回波在分析和预报强对流天气中的作用，得出以下结论：（1）上游移动强回波的出流边界导致的弱窄带回波是大风预警的重要判断参考；（2）在合适的层结状态和抬升条件下，弱窄带回波会强烈发展，并导致局地雷雨大风，这类强对流天气的发展有两个比较重要的阶段：弱窄带回波上初始回波的发展和回波跃增；（3）下击暴流造成的地面出流在雷达回波上表现为近似圆弧的弱窄带回波，这种弱窄带回波与其他雷达观测特征以及地面观测相结合，有助于对产生下击暴流的对流云的发生发展过程进行细致分析。

The character of this new method is that the mechanism of the GA is not changed but the search space and the coefficient of the adjustment of th e optimization parameter are reduced continually, which leads to generation evolution to the next generation in order to produce better optimization indivi duals so as to improve the performance of the GA and get over the disadvantage o f the GA.

提出一种新的混合算法--变尺度混沌遗传算法，该算法把遗传算法和混沌算法混合在一起，在不改变GA搜索机制的同时，根据搜索进程，不断缩小优化变量的搜索空间及调节系数，引导种群进行新一轮进化，从而产生更优的最优个体，改善了GA的性能，有效地克服了GA存在的问题。
