ON SOME INTEGRATION BY PARTS FORMULATE FOR THE ASP-INTEGRAL

The main results of this paper are as follows；Let F be approximately continuous on[a,b]and g be of bounded variation on[a,b]. Then (APS)∫^ba Fexists if and only if (APS)∫^ba gdf existe. Furthermore,suppose (APS)∫^ba Fdy or (APS)∫^ba gdF exists, then we have (APS)∫^ba Fdg (APS)∫^bagdf=F(b)g(b)-F(a)g(a)     

提高抽送黄河水用泵寿命的重要途径

从保证抽送黄河水用泵（以下简称抽黄泵）的寿命和工作可靠性出发，提出了抽黄泵性能参数选择的原则：限制抽黄泵的单级扬程Ｈ；限制抽黄泵单级扬程Ｈ与转速ｎ的乘积Ｈｎ值。并给出抽黄泵性能参数的Ｈ·ｎ－Ｑ关系曲线和泵的比转速ｎ＿ｓ与单级扬程Ｈ的关系曲线。     

Do the Experimental Violations of Bell Inequalities Require a Non-Local Interpretation of Quantum Mechanics？

Since the data show that Bell inequalities are violated experimentally, we must conclude that any hidden variable theory （which correctly predicts experimental data ） will be non-local. But, to conclude that the experimental violations of Bell inequalities show quantum mechanics to be non-local is unjustified. Specifically, the key assumptions required to obtain a Bell inequality are （ 1 ） locality and （2） the assignment of meaningful （ non- negative） probabilities to seemingly physical correlations （Bell expresses these correlations via ＂ hidden variables＂ ）. Since the Bell inequality is violated by experiment, at least one of these assumptions is wrong. The widespread conclusion that locality must be relinquished is valid only if we retain the previously mentioned correlations （ ＂hidden variables＂ ）. We will demonstrate that the latter are not physical observables - they are not elements of physical reality.     

Construction of the HL-2A Tokamak

HL-2A is the first tokamak with divertor in China. The objectives of HL-2A are to produce more adaptable divertor configurations to study energy exhaust and impurity control, and to study enhanced core plasma confinement by profile control and moderate plasma shaping. HL-2A has well optimized operational flexibility and excellent accessi-bility for the diagnostic systems to facilitate various plasma experiments.
