    Making great strides in social economy, demands for the material is growing, at the same time,it also stimulates the development of logistics.The railway-water combined transportation of our country is being into a golden opportunity, With the support of national policy and the improvement of railway transportation capacity,it\u27s preparing for the development conditions of the railway-water combined transportation.What‘s the mixed, whether in traffic or on the quality of service about railway-water combined transportation, there is a big gap with developed countries. This paper analyze the main problems in the development process of China\u27s railway-water combined transportation, For solving these problems, the essay applies modern system theory, supply chain management and modern logistics theory, and coordination management, and other theoretical ideas,to construct coordination system and management system of railway-water combined transportation respectively to solve the problems that the development of railway-water combined transportation is limited from system angle.This article expounds the ability of the railway-water combined transportation system based on coordination,and illustrates the multi-path assignment Model from putting coordination theory into this system to optimize the system

    AbstractThis study aimed to understand energy metabolism distribution along the pericardium meridian and verify the correlation between the body surface (points), and classic meridian theory. A highly sensitive CO2 instrument was used to measure the transcutaneous CO2 emission at 13 points along the pericardium meridian line (12 points on the line and one point beyond the line) and 13 control points beside them. Results showed that the distribution of transcutaneous CO2 emission is highly related to the position on the body. Transcutaneous CO2 emission is significantly higher at P7 and P3, than the control points beside them. The points along the meridian and the points beside them were clustered with relative distance by SAS statistics software. Two distance matrixes were then obtained. The correlation coefficients between the points along the line and between the control points were calculated. The results showed that the 13th point beyond the line was far from the 12 points on the line (distance, 0.24), while acupoints on the line clustered earlier when compared with the non-acupoints. The average correlation coefficients among the acu-points was 0.65 which was significantly higher than 0.56, among the non-acupoints. No such characteristics were found among the control points. It was concluded that there is a strong correlativity of energy metabolism activity between the body surfaces along the meridian, and an even stronger correlativity between the acupoints on the meridian

    IPS Observation System for Miyun 50m Radio Telescope and Its Acceptance Observation

    Full text link
    Ground-based observation of Interplanetary Scintillation(IPS) is an important approach of monitoring solar wind. A ground-based IPS observation system is newly implemented on 50m radio telescope, Miyun station, National Astronomical Observatories, Chinese Academy of Sciences(NAOC). This observation system is constructed for purpose of observing the solar wind speed and scintillation index by using the normalized cross-spectrum of simultaneous dual-frequency IPS measurement. The system consists of a universal dual-frequency front-end and a dual-channel multi-function back-end specially designed for IPS. After careful calibration and testing, IPS observations on source 3C273B and 3C279 are successfully carried out. The preliminary observation results show that this newly developed observation system is capable of doing IPS observation.The system sensitivity for IPS observation can reach over 0.3Jy in terms of IPS polarization correlator with 4MHz bandwidth and 2s integration time.Comment: 8 pages, 7 figure
