The Reason Why Our Country’S Export of Textile Was Limited
Jin Zhang,Ruiqi Qin
International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v3n9p58
Abstract: Our country is the biggest textile export country of the world. Now for the textile industry of our country, it is a period of facing the expansive world market, and getting a new opportunity to improve. But with the opportunity, we also face much more challenges. Seen from outside, EU and US set limits, which make textile companies into an austere condition? Setting limits, anti-dumping, and its chain-reaction, make textile export of our country face an austere and complicated international trade condition. Seen from inside, some relative policies which our country made to vindicate new trade orders, and some problems which the textile industry had, are also have influence on our country’s export of textile to some extent. The purpose of research of this essay is to find relevant countermeasures by investigating the reason of export restriction, then make sure that our country’s textile export can be carried though successfully.

Numerical Study of Elastic Wave Propagation Characteristics in Cracked Rock  [PDF]
Kaifeng Han, Ruiqi Cao
Journal of Applied Mathematics and Physics (JAMP) , 2014, DOI: 10.4236/jamp.2014.26046
Abstract:

Numerical methods can provide extremely powerful tools for analysis and design of engineering systems with complex factors that are not possible or very difficult with the use of the conventional methods. In this paper, we use the 2-D boundary element method (BEM) program to model elastic wave excited by a point explosive source propagating in cracked rocks. As an example, we consider the typical crack distributions in rocks, both models for the real crack structure are also talked about. The elastic wave propagating in rocks with aligned cracks and parallel fractures is assumed. Effects of different crack parameters, such as crack scale length and crack density are analyzed. Numerical results show that the BEM is a powerful interpretive tool for understanding the complicated wave propagation and interaction in cracked solids.

The Magnetic Field Distribution of Type II Superconductors Based on the Modified GL Equations  [PDF]
Ruiqi Huang, Weilong She
Journal of Applied Mathematics and Physics (JAMP) , 2016, DOI: 10.4236/jamp.2016.44077
Abstract:

The standard Ginzburg-Landau (GL) equations are only valid in the vicinity of the critical temperature. Based on the Eilenberger equations for a single band and s-wave superconductor, we derive a modified version of the standard GL equations to improve the applicability of the standard formalism at temperature away from the critical temperature. It is shown that in comparison with previous studies, our method is more convenient to calculate and our modified equations are also compatible with a dirty superconductor. To illustrate the usefulness of our formalism, we solve the modified equations numerically and give the magnetic field distribution in the mixed state at any temperature. The results show that the vortex lattice could be still observed even away from the critical temperature (e.g., T/Tc = 0.3).

Long-term Efficacy of Radiofrequency Ablation Combined with Chemotherapy ?in the Treatment of Patients with Advanced Non-small Cell Lung Cancer?-A Retrospective Study
Shuhui DU, Da QIN, Ruiqi PANG, Yeqing ZHANG, Siqi ZHAO, Mu HU, Xiuyi ZHI
- , 2017, DOI: : 10.3779/j.issn.1009-3419.2017.10.03
Abstract: Background and objective Radiofrequency ablation (RFA) combined with chemotherapy has a certain short-term therapeutic effect for the treatment of advanced non-small cell lung cancer (NSCLC), but whether it can improve the long-term survival rate of patients is still controversy. This study retrospectively analyzed the difference of long-term efficacy between RFA combined with chemotherapy and chemotherapy alone in the treatment of patients with advanced NSCLC. Methods A total of 77 patients with stage IIIb and stage IV NSCLC who underwent radiofrequency ablation and chemotherapy in the Department of Thoracic Surgery, Xuanwu Hospital, Capital University of Medical Sciences from September 2009 to December 2015 were enrolled as the treatment group. Chemotherapy with no radiofrequency ablation was performed in 56 patients with stage IIIb and stage IV NSCLC as the control group. Two groups of patients were followed up by telephone about their living conditions. “Survival” package of R software version 3.4.1 was used for statistical analysis. Two sets of data baseline levels were tested by chi-square test. The bias was processed by Cox regression model and the survival curve was plotted using covariate mean substitution method. Results The first-year survival rate of the treatment group was 70.74%, the two-year survival rate was 39.31% and the median survival time was 22.1 months. The one-year survival rate was 54.54% in the control group, the two-year survival rate was 19.49%, the median survival for 18.1 months. The long-term survival rate of the treatment group was better than that of the control group (P<0.05, OR=0.571). Conclusion Radiofrequency ablation of lung cancer combined with chemotherapy can significantly improve the 2-year survival rate of patients with stage IIIb and stage IV NSCLC.
An Evaluation of the English Immersion Approach in the Teaching of Finance in China
Ruiqi Zhou
English Language Teaching , 2008, DOI: 10.5539/elt.v1n2p71
Abstract: The English immersion teaching approach adopted by SEIB of GDUFS in China was developed on the basis of the immersion theory which was originally developed in North America. Its purpose is to create a learning environment in which the students acquire knowledge in business with English as the main carrier. The adoption of this approach aims to cultivate students with qualifications in both English language proficiency and business knowledge and skills. EDIF is one of the departments within SEIB that has implemented this approach since its establishment in 2001. The paper analyzes the implementation of English immersion teaching approach in the teaching of finance in EDIF from the perspectives of curriculum design, teacher training and recruitment, textbook selection and compilation and classroom teaching. Finally by comparing the results of language proficiency tests of EDIF students and those of the English majors of other colleges in China and by analyzing the employment situation of EDIF graduates, this paper concludes that students of EDIF outperform the other college students in both English language proficiency and employment competitive advantage. This indicates that English immersion teaching approach adopted by EDIF is effective and successful in the cultivation of students in both English proficiency and business knowledge.

Mathematics , 2013,
Abstract: We study the existence problem of harmonic maps with potential from $\mathbb{R}^2$ into $S^2$. For a specific class of potential functions on $S^2$, we give the sufficient and necessary conditions for the existence of equivariant solutions of this problem. As an application, we generalize and improve the results on the Landau-Lifshitz equation from $\mathbb{R}^2$ into $S^2$ in \cite{G_S} due to Gustafson and Shatah.
