Based on expansion of ODF in series of Generalized Spherical Harmonics by Bunge, we design programming in Orientation Distribution Function for polycrystal which contained five thousands crystals based on increment arithmetic of Voronoi. Geometrical data information, ODF of every crystal in polycrysal are imported to Open Graphics Library to draw, that means we implement visualization of ODF for every crystal in polycrystal.

It consists of fitting seismic ray traveltimes and positions to data calculated by ray tracing. In order to improve inversion stability and efficiency, seismic ray is described by Hamilton function and ray tracing is done in phase space. Validation tests on synthetic and practical data are analyzed. The tests show that this tomographic method is effective for estimating velocity field in complex media.

Also, a learning style involves a theoretical model that proposes that individuals have preferred ways in which they learn; learning styles typically involve visual representation, vocal explanations, and practical examples; experiential learning proposes several ways in which an educator can accommodate these learning styles, although all such styles have a bias toward practical expression and place less emphasis on theoretical expressions of learning.

同时，学习风格包含一种理论模型，主张学习者个体有较喜爱的学习方式，并通过这种方式来学习。它通常包含视觉表征、有声解说和实例；经验学习提出了一些方法，通过这些方法教育者可以帮助这些学习风格更好地适应，尽管所有这些风格更偏重对学习实践的表述而较少注重学习理论的表述。

Through discussing the transformation of the system of lawyers during the generation and development of it, and analyzing the phenomena of practicing alienation which have emerged from the Chinese lawyering under Chinese system of lawyers in force, and combining the relevant internal and external theories, we hope to demonstrate some opinions.The first, the external conditions which included the considerable authoritative position of the law and the widespread acceptance by civilian under the rule-by-law situation of the west as England, U-S-A, France and Germany, and the internal conditions which included the great professional practical skills and the improvement of the autonomous and self-governing systems, had formed a great solid base for the establishment and development of the system of lawyers of the West.
