A multi-line wavelength sweep techniqueand a weighted averaging technique were proposed for better gas detection. By selecting appropriatesystem parameters, 6 strong absorption lines near 1 530 nm of C2H2 were obtained with good spectrumresolution in one scanning period. One group with higher absorption coefficients was used for relativelylow gas concentration detection and the other with lower absorption coefficients was used for relativelyhigh gas concentration. Both the groups can be used for medium gas concentration detection. For variousconcentration cases, by choosing proper absorption lines and performing weighted averaging, detectionaccuracy can be obtained over an extended detection range. The minimum detection limit could be verylow after optimization.展开更多

Methods: A total of 90 cases of knee osteoarthritis were evenly randomized into Ba-He technique group (observation group) and common technique group (control group), with 45 cases in each group. Zusanli (足三里 ST 36), Heding (鹤顶 EX-LE 2) and Dubi (犊鼻 ST 35 ) were punctured respectively in Ba-He technique and common technique in the two gr oups. The therapeutic effects of the two groups were compared after one course o f treatment (10 sessions) in accordance with Japanese assessment criteria for kn ee-joint functions. Results: After treatment, among the 74 and 7 1 affected knees in the observation and control groups, the therapeutic effect was excellent in 42 (56.8%) and 26 (36.6%) knees, fine in 14 (18.9%) and 20 (28.2%), OK in 10 (13 .5%) and 11 (15.5%), and poor in 8 (10.8%) and 14 (19.7%) respectively. The ther apeutic effect of the observation group was significantly better than that of co ntrol group (P<0.01). Conclusion: The Ba- He technique of acupuncture applied to the above-mentioned three acupoints exerted remarkable therapeutic effect for k n ee osteoarthritis, which is obviously better than that of the common needling te chnique.展开更多

Cultural dimension, as one of the three key dimensions of eco-translatology, plays a very important role in translating. With its basis on cultural dimension of eco- translatology, this paper aims to present transformation techniques of parataxis and hypotaxis between Chinese and English. It is suggested that, with the cultural dimensional transformation techniques of parataxis and hypotaxis, translators should exert their subjectivity and creativity to achieve in maximizing the degree of holistic adaptation and selection for achieving successful translations.展开更多
