Inequalities for inscribed simplexes

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex.     

传播高校文化 推动高校发展

高校文化的内部功能有：(1)影响成员意识和规范成员行为，(2)增强学校凝聚力，(3)调节学校内部的社会关系；外部功能有：(1)利用组织意识指导学校与环境互动，(2)利用高校文化特征树立学校形象，(3)利用特定的高校文化适应环境。高校文化的内容包括：意识体系，制度性规范，行为基本模式，象征性符号和模范人物故事和传说等。高校文化的主要特征应与各校特有专业相联系。高校文化内部传播的目的是维持学校内部统一、实现整体协调和整体运作；外部传播的目的是突出本校的文化个性，给公众留下深刻的识别印象，扩大本校对，公众的影响力。     

The Politics of Curriculum and Instructional Design/Theory/Form: Critical Problems, Projects, Units, and Modules

What should be learned? How should it be organized for teaching? These seemingly simple questions are deceivingly political. Curriculum theorists are preoccupied with the politics of the first question at the expense of the realpolitik of the second. Instructional designers are preoccupied with the realpolitik of the second question at the expense of the politics of the first. I argue that conceptual distances between curriculum theory and instructional design are based on divisions of labour established during the 1960s. After decades of neglect, curriculum theorists, and specifically critical theorists, appear clueless when it comes to curriculum design and the realpolitik of their causes. When it comes to the realpolitik of practice their political causes are formless. Quite the opposite of critical theorists, instructional theorists nearly mastered the realpolitik of form but have no political causes. I argue that, to contradict the status quo of C&;I, curriculum theorists will have to dirty their hands with the realpolitik of form and instructional designers will have to clutter their heads with theory.     

试析大清律中例的地位和作用

清代律例合编的法典编纂形式和“有例不用律”的明确规定，使得清例的法律地位大大提高、律的法律地位大为降低。律例合编一度协调了律例矛盾，例对于律的补充、修改、废止作用也曾适应了统治的需要。但是，由于例多为一人一事而设，为贪官污吏徇私枉法留下了很大的空间，导致吏治腐败，加速了清朝的灭亡。     

论视觉传达设计的新视点

视觉是人类获取外部信息的主要媒介,视觉传达的目标不仅是完成简单的视觉信息的传递,更是要给人以情感上的感染和满足,实现视觉沟通。视觉传达设计就是要通过设计将视觉元素所包含的各种信息准确清晰地传达给受众,同时给予受众更多的审美感受。传统的观点往往将视觉传达设计等同于平面设计,但是随着社会的不断发展以及新技术的应用,视觉传达设计已经不能被局限在平面设计的范围内,同视觉媒介相关联的设计领域包括空间立体设计、动态设计都属于视觉传达设计的范畴。     

阅读活动中的范化与异化

阅读活动是间接交际行为，存在作者、文本、读者三极，阅读是三极的统一，即读者以文本为基础，与作者进行对话，这就是范化阅读，反之就是异化阅读。应当在阅读教学中提倡范化，正确认识异化。

Source extension based on ε-entropy

It is known by entropy theory that image is a source correlated with a certain characteristic of probability. The entropy rate of the source and ? entropy (rate-distortion function theory) are the information content to identify the characteristics of video images, and hence are essentially related with video image compression. They are fundamental theories of great significance to image compression, though impossible to be directly turned into a compression method. Based on the entropy theory and the image compression theory, by the application of the rate-distortion feature mathematical model and Lagrange multipliers to some theoretical problems in the H.264 standard, this paper presents a new the algorithm model of coding rate-distortion. This model is introduced into complete test on the capability of the test model of JM61e (JUT Test Model). The result shows that the speed of coding increases without significant reduction of the rate-distortion performance of the coder.

Tunable polarization of high numerical-aperture objective with phase plate

The intensity distribution of depolarized field in the focal region of a high numerical-aperture optical system was investigated and found that the depolarization effect is tunable by the plate. The depolarization effect gains with the increase of the inner convergence angle of the phase plate, goes through a dramatic descent when the angle is larger than 30° and begins to come back when the angle reaches a threshold of respectively 60°and 65° for the orthogonal diffractive field and the longitudinal diffractive fields. This reveals two convergence points where the depolarization effect is the strongest and weakest, respectively, suggesting that the pure phase plate can be a promising method for altering depolarization diffractive fields and constructing optical instruments.
