Abstract: According to the properties of influences of geoelectric field on solution seepage, a model of electro-dynamic seepage has been established; and the influences have been investigated through experiments. The results indicate that it is obvious that the geoelectric field affects the seepage properties; and the electro-dynamic seepage properties are affected by factors such as the intensity of geoelectric field, the permeability of rock mass, the characters of leaching solution and so on. Under the same pressure gradient, the seepage velocity of leaching solution well increases with the intensity of positive electric field, and decreases with the negative electric field. The seepage diffusibility of leaching solution and its wetting ability to fractured rock mass can be enhanced or weakened by the electric field.

Abstract: Under the effective mass approximation,some empirical formulas are obtained numerically concerning the correlations between the quantum well widths of finite potential barrier structure and those of infinite potential barrier structure under the circumstance that the ground state energies of two different models are equal in electric field,which match well with the results given by others.Then the wave functions and binding energies of excitons are analyzed,verifying the rationality to replace the effective width in electric field with that in zero field.

Abstract: 目的观察上海市杨浦区美沙酮维持治疗门诊开展动机强化治疗的应用效果。方法60名新近接受美沙酮维持治疗的*********依赖者被随机分为干预组(n=30)和对照组(n=30)。干预组患者接受常规美沙酮维持治疗联合12周的动机强化治疗,对照组接受常规美沙酮维持治疗。比较两组的维持治疗情况、吗啡尿检结果及成瘾严重程度指数。结果经12周动机强化治疗后,干预组与对照组平均服药天数(66 d和54 d)、尿检阴性次数(8.1次和6.2次)的差异均无统计学意义(P>0.05)。但是在24周观察期内,干预组的职业/社会支持状况、毒品使用情况、乙醇滥用情况及家庭/社会关系改善程度显著优于对照组。结论在上海市杨浦区开展的动机强化治疗未明显提高美沙酮维持治疗的依从性,但有助于美沙酮维持治疗门诊的*********依赖者改善其躯体健康状况、职业/社会支持状况、毒品使用严重程度。
: ObjectiveTo explore the effect of enhancing motivation (EM) of methadone maintenance treatment (MMT) clinic in Yangpu district of Shanghai.MethodsA total of 60 heroin dependents who recently underwent MMT were randomly divided into the control group (n=30) and intervention group (n=30). Patients of the intervention group underwent MMT and 12 weeks of EM and patients of the control group only underwent MMT. Results of MMT, morphine test, and addiction Severity Index (ASI) of two groups were compared.ResultsThe differences of average medication days (66 d versus 54 d) and number of negative urine tests (8.1 versus 6.2) between two groups were not statistically significant after 12 weeks of EM (P>0.05). But the professional and social supports, severity of drug use, alcohol addiction, and family/society relation of the intervention group were remarkably better than those of the control group during the 24 weeks of observation.ConclusionThe EM conducted in Yangpu district of Shanghai does not significantly improve the effect of MMT, but is helpful for improving the physical health and professional and social supports of heroin dependents, and decreasing the severity of drug use

Abstract: In the paper, we present the experimental results about the relationship between the plasma parameters' distribution and its target structure. The diagnostic results show that the characteristics of electron temperature and electron density distributions depend strongly on the target structure. The ionization state distributions of different targets are also discussed and compared with the theoretical calculated results for a simple model.

Abstract: The generalized gradient approximation (GGA) based on density functional theory(DFT) is used to analyze the structural and electronic properties of the unclassical endohedral fullerene M@C22(M=Sc, Ti, V, Cr, Mn, Fe, Co and Ni). It is found that the ground-state structure of the unclassical fullerene C_{22 }is a spin singlet cage containing one four-membered ring and the doping of transition metal atom can obviously enhance the stability. It is discovered that the C-M bond have both the covalent and the ionic characteristics. The analyses of magnetism, energy levels, orbital wave functions and density of states show the hybridization between the 3d orbital of M atom and the C atomic orbital in C22. In addition, Ti, Cr, Fe and Ni atoms become non-magnetic after they have been doped into the C22.
