A compact patch antenna is designed, which is with structures of cross-shape slot, Complementary Split Ring Resonator(CSRR), and loaded transmission line. To implement the compactness in size, these structures are etched on the ground plane, then the input impedance has been improved. The CSRR is employed to improve impedance matching between the source and radiation patch, and the cross-shape slot on the radiation patch is utilized to increase the bandwidth. The design is validated by comparison of realistic field simulation with measurement results of an antenna prototype. The presented antenna is much smaller in size than conventional antennas with CSRR, showing good performances at the resonant frequency. The experimental results accord well with simulated results. 展开更多

A phillipsite as one of oceanic authigenic zeolites gradually forms from alteration of volcanic glass under low temperature and pressure. In this paper physical property and chemical and mineralogical compositions ofsome zeolite grains collected from the study area in the North Pacific Ocean are first comprehensively studied, andthey are defined as phillipsite. Then, statistics of grain percentage of the phillipsite widely-distributed at 35 sitesin the study area in the deep-sea sediments were made ; it has been found that they mainly occur in the two sediments: red clay and calcareous ooze, and are rich in the former. Finally, the authors preliminarily discuss the formation process of the phillipsite on the basis of this study results, together with the view points of predecessors. 展开更多

Objective:Objective:To observe the therapeutic effect of cross-shaped moxibustion on the conception vessel and belt vessel for dysmenorrhea due to qi and blood deficiency.Methods:Taking Shenque(神阙CV8)as the center,up to Zhongwan(中脘CV12),down to Zhongji(中极CV3),and both sides to Daimai(带脉GB26),the above mentioned were treated area.The patient’s umbilicus was filled with the herbal powder for moxibustion and the powder was also scattered in a straight line along the treated area.The two sheets of mulberry paper were put in a cross way on the herbal powder for moxibustion,and the cross-shaped moxibustion box was put on the paper.The ginger paste was put into the box to a height of 3 cm and pressed tightly with a tongue depressor,the margin of the ginger paste should be clinged to the moxibustion box.The moxa cones were put end to end in the groove on the median of the ginger paste and ignited orderly.When the cones were burnt completely,the new cones were used and ignited.Three cones were adopted in succession in each treatment.The treatment was given once a week,and three treatments as one course,the therapeutic effect was evaluated after two courses of treatment.Results:There were 16 cases cured,5 cases effective and 2 cases non-effective in all.The total effective rate was 91.3%.Conclusion:Coss-shaped moxibustion on the conception vessel and belt vessel has sound effect for dysmenorrhea due to qi and blood deficiency. 展开更多
