In order to accurately measure an object’s three-dimensional surface shape,the influence of sampling on it was ***,on the basis of deriving spectra expressions through the Fourier transform,the generation of CCD pixels was analyzed,and its expression was ***,based on the discrete expression of deformation fringes obtained after sampling,its Fourier spectrum expression was derived,resulting in an infinitely repeated"spectra island"in the frequency ***,on the basis of using a low-pass filter to remove high-order harmonic components and retaining only one fundamental frequency component,the inverse Fourier transform was used to reconstruct the signal strength.A method of reducing the sampling interval,i.e.,reducing the number of sampling points per fringe,was proposed to increase the ratio between the sampling frequency and the fundamental frequency of the *** was done to reconstruct the object’s surface shape more accurately under the condition of m>*** basic principle was verified through simulation and *** the simulation,the sampling intervals were 8 pixels,4 pixels,2 pixels,and 1 pixel,the maximum absolute error values obtained in the last three situations were 88.80%,38.38%,and 31.50%in the first situation,respectively,and the corresponding average absolute error values are 71.84%,43.27%,and 32.26%.It is demonstrated that the smaller the sampling interval,the better the recovery *** the same four sampling intervals in the experiment as in the simulation can also lead to the same *** simulated and experimental results show that reducing the sampling interval can improve the accuracy of object surface shape measurement and achieve better reconstruction results.

An Outline of the Grand Unified Theory of Gauge Fields

引用

Journal of Modern Physics 2023年第3期14卷 212-326页

作者： Bi qiao Wuhan University of Technology Wuhan China

This paper attempts to propose a grand unified guiding principle of gauge fields from the mathematical and physical picture of fiber bundles: it is believed that our universe may have more fundamental interactions than the four fundamental interactions, and the gauge fields of these fundamental interactions are just a unified gauge potential on the fiber bundle manifold or the components connected to the bottom manifold, that is, our universe;these components can meet the transformation of gauge potential, and even can be transformed from a fundamental interaction gauge potential to another fundamental interaction gauge potential, and can be summarized into a unified equation, namely the expression of the generalized gauge equation, corresponding to the gauge transformation invariance;so gauge transformation invariance is a necessary condition to unify field theory, but quantization of field is not a necessary condition;the four (or more) fundamental interaction fields of the universe are unified into a universal gauge field defined by the connection of the principal fiber bundle on the cosmic base manifold.

随着我国新一轮新高考改革的推进、高中育人方式的变革,生涯教育成为一个时代新命题。在这样的政策背景下,在高中阶段我国高中生不仅面临过去的选专业、选大学的难题,而且面临着选课、选考、选职业、选人生等更深层的思考。生涯教育面对的是处于不同发展阶段的个体,是一种贯穿个体成长的教育。在我国,生涯教育不仅要满足学生个性发展的需要,顺应终身学习时代的要求,还要符合我国社会发展的人才诉求。经过几年探索,当前我国高中生涯教育仍存在课程狭窄化、形式化和功利化等现象,需要从明确生涯教育的内涵、地位,保障生涯教育的师资和课程资源,破除传统“唯分数论”,领悟生涯教育的意义等方面着力改进。

Recent advances in the role of toll-like receptors and TLR agonists in immunotherapy for human glioma

Protein & Cell 2014年第12期5卷 899-911页

Gliomas are extremely aggressive brain tumors with a very poor prognosis. One of the more promising strat- egies for the treatment of human gliomas is targeted immunotherapy where antigens that are unique to the tumors are exploited to generate vaccines. The approach, however, is complicated by the fact that human gliomas escape immune surveillance by creating an immune suppressed microenvironment. In order to oppose the glioma imposed immune suppression, mol- ecules and pathways involved in immune cell matura- tion, expansion, and migration are under intensive clinical investigation as adjuvant therapy. Toll-like receptors （TLRs） mediate many of these functions in immune cell types, and TLR agonists, thus, are currently primary candidate molecules to be used as important adjuvants in a variety of cancers. In animal models for glioma, TLR agonists have exhibited antitumor proper- ties by facilitating antigen presentation and stimulating innate and adaptive immunity. In clinical trials, several TLR agonists have achieved survival benefit, and many more trials are recruiting or ongoing. However, a second complicating factor is that TLRs are also expressed on cancer cells where they can participate instead in a variety of tumor promoting activities including cell growth, proliferation, invasion, migration, and even stem cell maintenance. TLR agonists can, therefore, possibly play dual roles in tumor biology. Here, how TLRs and TLR agonists function in glioma biology and in anti-gli- oma therapies is summarized in an effort to provide acurrent picture of the sophisticated relationship of gli- oma with the immune system and the implications for immunotherapy.

在Inventor二次开发生成工程图样的过程中,需要给工程图样添加各种标注,标注的添加以视图中的线条为基础.对于系列化的零部件,其三维模型变动前后视图中同一线条的序号必须保持不变才能准确添加标注,但系统序号随着三维模型的改变而变动,所以需要为视图中的线条添加人工序号来满足要求.通过对视图中线条的分析,根据其形状特点形成线条集合,并进一步找到了根据线条的相对位置关系编排人工序号的4种方法.对应线条的人工序号固定,保证了工程图样中各种标注位置的准确性.

Analytical evaluation of hybrid feedback scheme for OFDMA system

The Journal of China Universities of Posts and Telecommunications 2013年第4期20卷 34-38页

作者： SUN qiao-yun CHAI Wen-yan YANG Xiu-yun SUN Kai WU Cui-ting Electronic and Information Engineering Department Beijing City University College of Electronic Information Engineering Inner Mongolia University

This paper first introduces the performance analysis of two classical channel quality indicator （CQI） feedback schemes which are best-n feedback and the threshold based feedback and derives the mathematical expressions of average capacity which is described by Theorem 1 and 2. Then, a reduced feedback scheme is designed for multiple traffics and multi-channel. The novel scheme combines the best-n feedback and the threshold based feedback together to reduce the feedback overhead. The proposed scheme can not only guarantee the quality of service （QoS） requirement of real time （RT） traffic but also reduce feedback overhead at the cost of a marginal increased downlink overhead. Simulation results demonstrated the good performance of the proposed feedback scheme.
