In this paper full-energy peak (photopeak) efficiency and photopeak attenuation coefficient of 3'' × 3'' naI(Tl) well-type scintillation detector were calculated using gamma-rayisotropic radiating point sources (with photon energy: 0.245, 0.344, 0.662, 0.779, 0.964, 1.1732, 1.333 and 1.408 meV) placed outside the detector well. These energies were obtained from 152Eu, 137Cs and 60Co. The relations between the full energy peak efficiency and photopeak attenuation coefficients, were plotted vs. photon energy at different sources to detector distance, and it found that the full energy peak efficiency decreased by increasing the distance between the source and the detector.

The decay widths of Υ（nS）→d^＊（2380）＋X with n=1,2,3 are studied in a phenom.nological way. With the help of crossing symmetry, the decay widths are obtained by investigating the imaginary part of the forward scattering amplitudes between d^＊ and Υ（nS）. The wave functions of d^＊ and deuteron obtained in previous studies are used for calculating the amplitude. The interaction between d^＊（d） and Υ is governed by the quark-meson interaction, where the coupling constant is determ.ned by fitting the observed widths of Υ（nS）→d＋X. The numerical results show that the decay widths of Υ（nS）→d^＊＋X are about 2-10 times smaller than that of d＋X. The calculated mom.ntum of d^＊ is in the range 0.3-0.8 GeV. Therefore, it is very likely that one can find d^＊（2380） in these semi-inclusive decay processes.

对于各种光学类别的不透明矿物的反射率的性质,目前使用的符号是多样的和矛盾的。为了调研这些符号和推荐一套符号系统,1974年国际矿物协会(ImA)的矿石显微镜委员会(COm)建立了符号和定义委员会。委员会曾提供一个暂时报告,并在1978年新西伯利亚的COm会议上通过。然而,这报告的发表被推迟到和定量资料档案的编辑委员会的报告一起公布。下面是在1980年奥尔良的COm会议上通过的供发表的修改报告。

Hypocreomycetidae is a highly diverse group with species from various habitats. This subclass has been reported as pathogenic,endophytic, parasitic, saprobic, fungicolous, lichenicolous, algicolous, coprophilous and insect fungi from aquatic andterrestrial habitats. In this study, we focused on freshwater fungi of Hypocreomycetidae which resulted 41 fresh collectionsfrom China and Thailand. Based on morphological and phylogenetic analyses, we identified 26 species that belong to twoorders (Hypocreales and microascales) and six families (Bionectriaceae, Halosphaeriaceae, microascaceae, nectriaceae,Sarocladiaceae and Stachybotryaceae). Ten new species are introduced and 13 new habitats and geographic records arereported. mariannaea superimposita, Stachybotrys chartarum and S. chlorohalonatus are recollected from freshwater habitatsin China. Based on phylogenetic analysis of combined LSU, ITS, SSU, rpb2 and tef1-α sequences data, Emericellopsisis transferred to Hypocreales genera incertae sedis;Pseudoacrem.nium is transferred to Bionectriaceae;Sedecimiella isplaced in nectriaceae;nautosphaeria and Tubakiella are excluded from Halosphaeriaceae and placed in microascalesgenera incertae sedis;and Faurelina is excluded from Hypocreomycetidae. Varicosporella is placed under Atractium as asynonym of Atractium. In addition, phylogenetic analysis and divergence time estimates showed that Ascocodina, Campylospora,Cornuvesica and Xenodactylariaceae form distinct lineages in Hypocreomycetidae and they evolved in the family/order time frame. Hence, a new order (Xenodactylariales) and three new families (Ascocodinaceae, Campylosporaceae andCornuvesicaceae) are introduced based on phylogenetic analysis, divergence time estimations and morphological *** character state analysis is performed for different habitats of Hypocreomycetidae including freshwater, marineand terrestrial taxa. The result indicates that marine and freshwater fungi evolved independently from terr

Galvanic corrosion of AZ31B joined with bare or Zn-coated DP590 steel by ultrasonic spot welding or linear friction stir welding was quantitatively studied by pre-defining anode and cathode in the lap joint samples. Corrosion volume and depth from mg anode surfaces exposed to 0.1 m sodium chloride solution was analyzed as functions of cathode surface type and welding method. Characterization of as-welded joints was performed to identify any microstructural feature of the bonding zone that could impact galvanic corrosion *** modeling with modified user subroutine was conducted to simulate the progression of mg corrosion in the same joint and electrode configurations used for the corrosion experim.nts. The experim.ntal results indicated that Zn-coated cathode surface can reduce mg galvanic corrosion significantly as galvanic polarization and cathodic current on Zn-coated surface remained relatively low for mg in the weld *** modeling described the growth of mg galvanic corrosion in a reasonable m.nner but showed limitation by underestimating the corrosion volume as it did not capture self-corrosion.
