In the new education system, it is an urgent problem for the mathematics teachers in higher vocational colleges to bring forth new ideas for the teaching methods, improve the students＇ interest in learning, and train the application-oriented talented personnel needed by the society. MATLAB software package can help set up a bridge and link for the mathematics teaching and the practical application. Its powerful numerical calculation ability can quickly solve all kinds of calculation problems, so that the basic thinking methods are more closely focused in mathematics teaching and also more conditions are created for mathematics teaching to combine the actual major conditions and life conditions. In this paper, the related problems in the implementation of mathematical modeling software MATLAB and model in higher vocational colleges are discussed.展开更多

Methyl orange was selected as degradation target for photocatalytic experiments. The photocatalytic activities were investigated by visible spectro- photometer. Photocatalytic kinetics parameters were studied by the Langmuir-Hinshelwood model and Arrhenius formula. It was observed that the sea urchin-like morphology dramatically improved the photocatalytic activity of cuprous oxide. The photo-degradation belongs to the first-order reaction and the maximum degradation rate could reach 94.37%. The activation energy and pre-exponential factor are 41.18 KJ·mol-1 and 1.07 × 106, respectively.

It is unique and become the mainstream of oriental art. Traditional Chinese painting is artistic conception as the soul, melting into poetry, books, paintings as a whole, poetic romance as the connotation, expressing feelings and thoughts. It exhibited virtual static beauty in thinking of Taoist philosophy of nature, becoming a unique Chinese aesthetic art. Artistic spirit is an important part and aesthetic standard of Chinese painting aesthetics, in the ＂paintings goods recorded,＂ ＂Lively spirit＂ is defined as the highest state of painting, artistic spirit is not a very mysterious thing, it was born from the pen and ink. NO pen and ink, no artistic spirit. Pursuing vivid artistic spirit, emphasizing ink skills, giving vent to feelings of oneself for its purpose, Chinese painting has generated a large number of outstanding works of art in thousands of years, constructed a unique cultural spirit, shaped the nation ＇ s aesthetic temperament and character.展开更多

Methods： A total of 80 cases with LIDH in conformity with the inclusion criteria were randomly divided into a treatment group or a control group by their visit order, 40 cases in each group. The points from the Governor Vessel, L1-L5 Jiaji （EX-B 2） points, from the first lateral line of the Bladder Meridian, Huantiao （GB 30）, Weizhong （BL 40） and Yanglingquan （GB 34） were selected for acupuncture in the treatment group. Shenshu （BL 23）, Dachangshu （BL 25）, Ashi （Extra） points and Weizhong （BL 40） were used for routine acupuncture in the control group. The clinical effects of the two groups after 2-course treatments and recurrence rates three months later were observed. The pain severity before and after treatments was assessed by visual analog scale （VAS）. The improvement of the patient＇s pathological situation was evaluated by the performance assessment of lumbar disease treatment from Japanese Orthopedic Association （JOA）. Results： After the treatment for two courses, there was no dropped-out case in the two groups. The curative rates and total effective rates were respectively 32.5% and 92.5% in the treatment group versus respectively 12.5% and 82.5% in the control group. The differences in the curative rates and total effective rates between the two groups were statistically significant （both P〈0.01）. After the treatment, VAS and JOA scores remarkably declined in the patients of the two groups, with statistical differences in comparison with those of the same group before treatment （both P〈0.05）. In follow-up check of three months, the recurrence rate was 10.7% in the cured and remarkably effective cases in the treatment group and was 29.4% in the control group. The recurrence rates of the two groups were statistically different （P〈0.05）. Conclusion： The aligned needling technique is remarkable in the clinical effects, obvious in the analgesic effects and low in the recurrence rate in the treatment of LIDH.展开更多
