The downward curve will go differently in different individual and outside environment. The scientist in The French Larisa Skin Microecology Research Center have worked out a theory which can effetely delay skin aging and recover skin health: help the skin microecology to get into a balanced state by a certain skill from outside, meantime supply new energy to skin, so to slow down the skin aging, and the unhealthy condition of skin also will be improved.

这条下行曲线会因为个体的不同或是外界环境的不同而呈现不同的趋势，法国瑞莎皮肤微生态研究中心的科学家们得出了一个有效延缓肌肤衰老和恢复肌肤健康的理论：从外界设法采取一定手段使皮肤微生态达到平衡，同时为肌肤补充新能量，肌肤的老化速度就会减缓，肌肤的不健康状况就会改善。

It is directly related to the development and exist of the enterprise. Seen from the dog-eat-dog market and the states of the coal enterprise. It is a logjam way to improve the price and increase the output of coal, but there is only way to improve the economical efficiently of coal through controlling the cost. But, on controlling of the cost, there is a great limitation in traditional product-centered cost calculation system.

从激烈的市场和煤炭企业自身的情况看，煤炭企业提高价格和提高产量的方法是行不通的，只有通过内部自身进行有效的控制成本才是提高煤炭企业经济利益的根本途径，而在控制成本方面，传统的以"产品"为中心的成本核算体系存在很大的局限性。

To solve this problem, based on the concept of graph theory we give a few models and arithmetic designs of virtual backbone in the environment of different application, and propose the corresponding routing mechanism with these virtual backbones. The major achievements are outlined as follows:The state of host's power or the time of host's online plays an important role in keeping stability of a virtual backbone. With a view to this feature, the paper introduces a simple and efficient heuristic algorithm for calculating the virtual backbone by seeking a minimum connected dominating set with maximal weight. The maximality of the weight-based choice of backbone nodes guarantees that the most suitable nodes have been chosen for the role of backbone nodes so that they can properly coordinate all the other nodes and keep stability of the virtual backbone in the network.
