Given a mesh, we first solve a Poisson equation to construct a scalar field and use it to generate some critical points. The cutting paths between the critical points and the boundaries are solved in the Poisson scalar field using the deepest descent method. For meshes with nonzero-genus, we construct a Harmonic scalar field, and connect the saddle points with the boundaries based on the Morse theory.

Finally, we present an arithmetic of multiplehypocentral, heterogenous dislocation, and a multirupture segment superposition model for simulating the earthquake deformation field. The simulated LOS interferometry map presents the distribution characteristics of the earthquake deformation field better than that of previous studied. Meanwhile, a suit of fault geometric parameters of the earthquake is also obtained by the study. Having a better effect upon simulating asymmetry, great dislocation, macro rupture field, and nonhomogeneity of dislocation than the traditional model, the multisegment method is a progress of this work. It provides a better explanation for the study on hypocentral parameters.

基于上述原因，本文对Okada线弹性位错模型的算法进行了改进，提出了"多震源、非均一位错分量、多破裂段叠加"的线弹性模型，该模型模拟出的形变场干涉纹图较好地体现了地震形变场的分布特征，并由此获得了一套较为完整的地震发震断层的几何学特征参数，为破裂带长度、破裂面方向、破裂面大小等震源破裂特征参数研究提供了较好的解释。

Divide numerous medium come from first quarter sell field terminal broadcast over a radio network the network, include royal seal the advertisement service battalion of sincere medium closes for 17.3 million dollar, grow 160.2% compared to the same period. On January 2, 2008, cent numerous medium finished pair of royal seal of sincere medium buy, this traded to strengthen the lead position that this company is selling network of field terminal broadcast the field further.

Discover finally,"Big profit is sent " in be being managed actually not only use the pensile billboard inside inn, will " cent is numerous " the advertisement of installation shows screen is intended keep out, and often be opposite " cent is numerous " advertisement shows screen is adopted cut off the power artificially, pull out the preventive action such as frequency line, still allow to sell a supplier to use the phonic video device of tripartite greatly, in " big profit is sent " sell brand advertisement is released in field, allow to be engaged in selling field advertisement platform management ad company greatly likewise even, sell in its advertisement information is released in field.

最终发现，"大润发"在实际经营中不但利用店内的悬挂广告牌，将"分众"安装的广告显示屏故意遮挡，而且经常对"分众"的广告显示屏采取人为断电、拔除音频线等妨碍行为，还允许大卖场供货商利用第三方的音视频设备，在"大润发"卖场中发布品牌广告，甚至允许同样从事大卖场广告平台经营的广告公司，在其卖场中发布广告信息。

For Permalloy/FeMn bilayers, the exchange field and coercivity decay exponentially in time with the application of an applied field antiparallel to the unidirectional anisotropy direction.
