Topics of Truth,Kindness and Aesthetics in Chinese Education1

The ideal goal to cultivate creative talents who "seek truth","strive for kindness" and "adore aesthetics " and are equipped with "perfect personality" should be achieved,which is expected to reach brand-new circumstances of "humans development and construction of completeness" and must and should explore "Truth","Kindness" and "Aesthetics" in Chinese education.This article is meant to explore "truth" of Chinese(language,article,literature) in the intellectual education from cognitive science and to promote students to get into quality of exploration;they should explore "kindness" in the moral education in Chinese(language,article,literature) from ethics,which is to urge wakefulness of students' moral consciousness;in addition,"aesthetics" in Chinese(language,article,literature) from aesthetic education is to spur students to construct free soul.

Research on Chinese Education Philosophy of "Truth, Kindness, and Aesthetics Combination "

Chinese Education Philosophy of "Truth, Kindness, and Aesthetics Combination" manifests in the research on Chinese education from aesthetics perspective. It aims at the "narrow and limited view" of "not the general aesthetics, but the artistic beauty only", and it aims at biased opinion of "the interest saying", "the fine arts saying", "the esthetic sense saying" on aesthetics. It also aims at serious distraction of "LEFT in form but RIGHT in essence" of the mainstream ideology "the thought", "the revolution", "politics" and so on. It is a complex study of Chinese education from the philosophy of the unity of Truth, Kindness, and Aesthetics of oriental aesthetics, the consensus of Truth, Kindness, and Aesthetics of Western aesthetics, and the identity of Truth, Kindness, and Aesthetics of Marx aesthetics. From aesthetics perspective, it studies Chinese education, "combing" the reversed relationships among "truth", "kindness" and "aesthetics" in Chinese, adopting the methods of "research with great ease", "cases study", and "combination of ration and perception", to achieve "truth" of in Chinese, "kindness" of and "aesthetics" of , promote the development of "Chinese intellectual education", "Chinese moral education", and "Chinese aesthetic education" harmoniously, to realize the "Truth, Kindness, and Aesthetics Combination" of Chinese education and to reach the brand-new boundary territory of "human development and integrity construction" effectively.

ON NEWMAN-TYPE RATIONAL INTERPOLATION TO |x| AT THE CHEBYSHEV NODES OF THE SECOND KIND

Recently Brutman and Passow considered Newman-type rational interpolation to ｜x｜ induced by arbitrary set of symmetric nodes in [-1,1] and gave the general estimation of the approximation error.By their methods one could establish the exact order of approximation for some special nodes. In the present paper we consider the special case where the interpolation nodes are the zeros of the Chebyshev polynomial of the second kind and prove that in this case the exact order of approximation is O（1/n｜nn）

ON THE COEFFICIENTS OF DIFFERENTIATED EXPANSIONS AND DERIVATIVES OF CHEBYSHEV POLYNOMIALS OF THE THIRD AND FOURTH KINDS

Two new analytical formulae expressing explicitly the derivatives of Chebyshev polynomials of the third and fourth kinds of any degree and of any order in terms of Chebyshev polynomials of the third and fourth kinds themselves are proved. Two other explicit formulae which express the third and fourth kinds Chebyshev expansion coefficients of a general-order derivative of an infinitely differentiable function in terms of their original expansion coefficients are also given. Two new reduction formulae for summing some terminating hypergeometric functions of unit argument are deduced. As an application of how to use Chebyshev polynomials of the third and fourth kinds for solving high-order boundary value problems, two spectral Galerkin numerical solutions of a special linear twelfth-order boundary value problem are given.

Precise integration methods based on the Chebyshev polynomial of the first kind

This paper introduces two new types of precise integration methods based on Chebyshev polynomial of the first kind for dynamic response analysis of structures, namely the integral formula method （IFM） and the homogenized initial system method （HISM）. In both methods, nonlinear variable loadings within time intervals are simulated using Chebyshev polynomials of the first kind before a direct integration is performed. Developed on the basis of the integral formula, the recurrence relationship of the integral computation suggested in this paper is combined with the Crout decomposed method to solve linear algebraic equations. In this way, the IFM based on Chebyshev polynomial of the first kind is constructed. Transforming the non-homogenous initial system to the homogeneous dynamic system, and developing a special scheme without dimensional expansion, the HISM based on Chebyshev polynomial of the first kind is able to avoid the matrix inversion operation. The accuracy of the time integration schemes is examined and compared with other commonly used schemes, and it is shown that a greater accuracy as well as less time consuming can be achieved. Two numerical examples are presented to demonstrate the applicability of these new methods.

A Method for Solving Fredholm Integral Equations of the First Kind Based on Chebyshev Wavelets

In this paper, we suggest a method for solving Fredholm integral equation of the first kind based on wavelet basis. The continuous Legendre and Chebyshev wavelets of the first, second, third and fourth kind on [0,1] are used and are utilized as a basis in Galerkin method to approximate the solution of integral equations. Then, in some examples the mentioned wavelets are compared with each other.

Explicit Shifted Second-kind Chebyshev Spectral Treatment for Fractional Riccati Differential Equation

This paper is confined to analyzing and implementing new spectral solutions of the fractional Riccati differential equation based on the application of the spectral tau method.A new explicit formula for approximating the fractional derivatives of shifted Chebyshev polynomials of the second kind in terms of their original polynomials is established.This formula is expressed in terms of a certain terminating hypergeometric function of the type_(4)F_(3)(1).This hypergeometric function is reduced in case of the integer case into a certain terminating hypergeometric function of the type 3 F 2(1)which can be summed with the aid of Watson’s identity.Six illustrative examples are presented to ensure the applicability and accuracy of the proposed algorithm.

A fourth-order variational inequality of the second kind arising in a plate frictional bending problem is considered. By using regularization method, the original problem can be formulated as a differentiable variational equation, and the corresponding discrete FEM variational equation is presented afterwards. Abstract error estimates and error estimates of the approximation are derived in terms of energy norm and L^2-norm.

Biochemical properties of norepinephrine as a kind of neurotransmitter secreted by bone marrow-derived neural stem cells induced and differentiated in vitro

BACKGROUND： It has been proved by many experimental studies from the aspects of morphology and immunocytochemistry in recent years that bone marrow stromal cells （BMSCs） can in vitro induce and differentiate into the cells possessing the properties of nerve cells. But the functions of BMSCs-derived neural stem cells（NSCs） and the differentiated neuron-like cells are still unclear. OBJECTIVE： To observe whether bone marrow-derived NSCs can secrete norepinephrine （NE） under the condition of in vitro culture, induce and differentiation, and analyze the biochemical properties of BMSCs-derived NSCs. DESIGN： A non-randomized and controlled experimental observation SETTING ： Institute of Neuromedicine of Chinese PLA, Zhujiang Hospital, Southern Medical University MATERIALS： This experiment was carried out in the Institute of Neuromedicine of Chinese PLA, Zhujiang Hospital, Southern Medical University. The bone marrow used in the experiment was collected from 1.5- month-old healthy New Zealand white rabbits. METHODS： This experiment was carried out in the Institute of Neuromedicine of Chinese PLA, Zhujiang Hospital, Southern Medical University. The bone marrow used in the experiment was collected from 1.5 month-old healthy New Zealand white rabbits. BMSCs of rabbits were isolated and performed in vitro culture, induce and differentiation with culture medium of NSCs and differentiation-inducing factor, then identified with immunocytochemical method. Experimental grouping： ①Negative control group： L-02 hepatic cell and RPMI1640 culture medium were used. ② Background culture group： Only culture medium of NSCs as culture solution was added into BMSCs to perform culture, and 0.1 volume fraction of imported fetal bovine serum was supplemented 72 hours later. ③Differentiation inducing factor group： After culture for 72 hours, retinoic acid and glial cell line-derived neurotrophic factors were added in the culture medium of BMSCs and NSCs as corresponding inducing factors. The level of NE in each group was detected on the day of culture and 5, 7, 14 and 20 days after culture with high performance liquid chromatography （HPLC）. The procedure was conducted 3 times in each group.Standard working curve was made according to the corresponding relationship of NE concentration and peak area. The concentration of NE every 1×10^7 cells was calculated according to standard curve and cell counting. MAIN OUTCOME MEASURES ： The level of NE of cultured cells was detected with HPLC; immunocytochemistrical identification of Nestin and neuron specific nuclear protein was performed. RESULTS： ① On the 14^th day after cell culture, BMSCs turned into magnus and round cells which presented Nestin-positive antigen, then changed into neuron-like cells with long processus and presented neuron specific nuclear protein -positive antigen at the 20^th day following culture. ② The ratio of NE concentration and peak area has good linear relationship, and regression equation was Y=1.168 36＋0.000 272 8X,r=-0.998 4. Coefficient variation （CV） was 〈 5% and the recovery rate was 92.39%（ Y referred to concentration and X was peak area）.③NE was well detached within 10 minutes under the condition of this experiment. ④ NE was detected in NSCs and their culture mediums, which were cultured for 7, 14 and 20 days respectively, but no NE in BMSCs, NSCs-free culture medium and L-02 hepatic cell which were as negative control under the HPLC examination. Analysis of variance showed that the level of NE gradually increased following the elongation of culture time （P 〈 0.01 ）. No significant difference in the level of NE existed at the same time between differentiation inducing factor group and basic culture group（P 〉 0.05）. CONCLUSION ： BMSCs of rabbits can proliferate in vitro and express Nestin antigen; They can differentiate into neuron-like cells, express specific neucleoprotein of mature neurons, synthesize and secrete NE as a kind of neurotransmitter.

Quality Analysis and High-Performance Liquid Chromatographic Fingerprint Analysis of New Cultivated Kind of <i>Lonicerae japonicae</i>Flos “Hua Jin 6” from Different Harvest Times

Lonicerae japonicaeFlos (LJF) is widely used in traditional Chinese medicines for the treatment of various diseases, which is now in great demand every year and has a broad development prospect. However, the flowering phase of common LJF varieties is so short, which seriously restricts the development of LJF industry. As a new cultivated kind of Lonicerae japonicae Flos, “Hua Jin 6” has characteristics in long flowering phase and conveniently picking, which makes it have a broad development prospect. The aim of this study is to provide scientific guidance for its suitable harvest period by measuring yield and quality of “Hua Jin 6” from different harvest time. Studies show that flower size had a slowly rising trend from the first day to the seventh day, and then slowly declined or kept stable. There were no significant differences of total phenolic acid contents in different samples from different days, but contents of total flavonoids were on the rise and up to maximum in the ninth day. The contents of total iridoids had an increasing tendency from the first day to the fifth day and then kept relatively stable in other days. We demonstrated that the quality of “Hua Jin 6” is relatively stable and suitable for harvesting in all flower buds white stage in term of HPLC fingerprints. Our findings can make it possible to select the suitable time for different harvest purpose.

KIND用法译评

在英语语言文学和日常英语中,有关kind,kindly以及kind of结构,语言学界的争论一直没有停止。但随着语义学研究的不断深入,人们对许多问题的认识渐趋理性。本文从语言学的视角对某些容易引起混淆和争执的问题作用法译评。

内窥kind of的弱陈法

美国英语教科书都要求学生在正式场合使用rather或somewhat，而不用kind of或Sort of。比如，最好说“It’s rather／somewhat cold today(今天有点冷)”，而不要说成“It’s kind of cold today”。这些教材的编写者对学生造句提出这种要求所依据的理由不外乎两点，其一，kind of和Sort of不是副词，因此不能用作状语修饰形容词；其二，kind of和Sort of属口语，其结构松散、不严谨，非正式用语，难登大雅之堂。有些所谓捍卫语言纯洁者尤其反对kinda、kinder或sorta、Sorter这样的缩写形式。
