In order to effectively abstract the texture and denoise but not damage the edge and other important details of image, Meyer (2001) proposed using elements of BV space and G space to characterize cartoon and details of image respectively. The authors present PDE of minimizing energy on the basis of Meyer's work, After the model is discretizated. projection algorithm and the method for ROF model are applied. Thus an image is decomposed into two parts, bounded variation component u and texture with noise υ.

Based on seismic source spectrum solution by multi-station and multi-event coda method, applying Brune seismic source model, we have got the source factors and spectra of 48 small earthquakes occurred before and after the Douhe earthquake of October 6 in 1995. The seismic moments, corner frequencies and stress drops are estimated from the spectra, and their correlation and variation with time before and after the Douhe earthquake are discussed.

The system characteristic, exists in any system, also exists in the enterprise flow, but because the system characteristic is hides to the system internality, just like the enterprise the constitution, but the traditional enterprise flow management and the management method, usually all by the outward appearance angle of view and backwardness indicators, to evaluate the condition that enterprise target reach, achieves the goal by the flow operation achievement the means, often neglects the constitution flow intrinsic physique the characteristic, even not mention to in order to conforms to the industry to need and the environmental variation, the development enterprise manages some kind of system characteristic which should have.

系统的特性，存在於任何系统中，亦存在於企业流程中，但是由於系统特性是隐於系统的内在，犹如企业的体质，而传统的企业流程管理与经营方法，通常皆以外观的视角与落后指标，以评估企业目标达成的状况，以流程运作作为达成目标的手段，往往忽略构成流程内在体质的特性，更遑论为符合产业需要与环境变化，发展企业经营应该具备的某种系统特性。
