Methods： The randomized, single blinded, parallel positive drug controlled method was adopted, with 82 patients assigned into two groups by envelop method. The 42 patients in the treated group received PYQC 3 times a day, 4 capsules each time taken orally; the 40 patients in the control group were given orally Fuyankang tablets （妇炎康片, FYKT） 3 times a day, 6 tablets each time. The therapeutic course for both groups was 2 months, and 2 courses of treatment were given successively to observe the comprehensive effect, changes of symptoms and signs before and after treatment. The effects of PYQC on hemorrheological character in part of the patients and on the pathogenetic chlamydia and mycoplasma were also observed. Results： The total effective rate in the treated group was 83.3%, which was insignificantly different from that in the control group （77.5%, P〉0.05）. However, PYQC could significantly lower the hemorrheologic indexes in patients and showed definite influence on the pathogenetic chlamydia and mycoplasma. Conclusion： PYQC has good therapeutic effect in treating chronic pelvic inflammation of Qi-stagnation with blood stasis syndrome, and showed definite effect on chlamydia and mycoplasma.展开更多

From these data, the dispersion curves of phase velocities of the fundamental mode Rayleigh wave along 209 paths are determined by using the two-station narrowband filtering cross-correlation method. Adopting tomography method, the distribution maps of phase velocities at various peri-ods in Yunnan region are inverted. The maps of phase velocities on profiles along 24N, 25N, 26N, 27N and 100.5E and the distribution maps of phase velocities at 3 periods in the study region are given. The results show that the phase velocity distribution in Yunnan region has strong variations in horizontal direction, and the phase velocity distribution in short-period range is closely related to the thickness of sedimentary layers in the shallow crust. The phase velocity in southern part of the Sichuan-Yunnan rhombic block encircled by the Honghe fault and Xiaojiang fault is obviously lower than that in surrounding areas. The epicentral locations of strong earthquakes in Yunnan region are mainly distributed in transitional zones between low and high phase velocities.展开更多

This arrangement was employed to investigate systematically the mechanism of facilitated potassium ion transfer by an ionophore dibenzo 18 crown 6(DB18C6) across a micro water/1,2 dichloroethane(W/DCE) interface supported at the tip of a silanized micropipette. Our experimental results verify that this facilitated ion transfer across the liquid/liquid interface did occur by an interfacial complexation dissociation process(TIC TID mechanism). The ratio of the diffusion coefficient of DB18C6 to that of its complexed ion in the DCE phase was calculated to be 1.74±0.07.展开更多

By the methods of Atkinson and Moya, the site response of each station and several source parameters are obtained and the inversion results from both methods are compared and analyzed. The frequency-dependent inelastic attenuation coefficient Q is estimated as Q( f )=323.2 f 0.506. The site responses of 14 seismic stations do not show significant amplification, which is consistent with their basement on rock. We also found the dependence of corner frequency on seismic moment, seismic moment on stress drop, source radius on stress drop.展开更多

Nonlinear multiple regression is used to fit the parameters of the modification model. Nonlinear modification function is discovered by BACON system by learning mixture data. Experiment results indicate that nonlinear color conversion by two step learning can further improve the accuracy when it is used for straightforward conversion from RGB to CMYK. An improved separation model based on GCR concept is proposed to solve the problem of gray balance and it can be used for three to four color conversion as well. The method proposed has better learning ability and faster printing speed than other historical approaches when it is applied to four color ink jet printing.展开更多

Then the structure was characterized by means of 1H NMR, IR, UV. By the method of ab initio HF and density functional theory (DFT) B3LYP, the geometric structures of the reagent intermediate, the product and its isomer were optimized and their total energies were calculated. The properties for the frontier molecular orbitals and the rules for energy distribution were analyzed systematically. It was shown that the energy of the nitrogen alkyl compound is lower than that of the oxy alkyl compound and the former is stable than the latter . This result is in accordance with the fact that 6 chloro 2 diethylaminoethyl 3(2H) pyridazinone is synthesized by the reaction of \{6 chloride \}2 diethylaminoethyl 3(2H) pyridazinone and 2 diethylaminoethyl chloride.展开更多

Then the unknown fictitious load functions along the fictitious boundary were expressed in terms of basic spline functions, and the boundary-segment-least-squares method was proposed to eliminate the boundary residues obtained. By the above steps, numerical solutions to the integral equations can be achieved. Numerical examples are given to show the accuracy and efficiency of the proposed method.展开更多
