In order to interpret the test results of crossweld specimens for application in practical welded components, the present paper studies.t.e high temperature behavior of laboratory cross weld specimens in terms of the uniax.al material tests and numerical simulations. It is found that the crossweld specimen may be used for the high temperature strength assessment, but can hardly be used for life assessment of the practical welded components, which depends on the loading conditions of the components.

Creep deformation localization is generally found in structures at high temperamture,typically in weldments. As.t.e heat affected zone (HAZ) in a weldment is very narrow, deformation in HAZ region can hardly be measured by conventional displacement gauge. A new method for measuring long-term local creep deformation was developed by quartz optical fiber and technique of digital image analysis. the creep deformations of base metal, weld metal and HAZ in weldments are thereby determined with crossweld specimens.

to investigate the nature of the Ψ（3770） resonance and to measure the cross section for e^＋e^-→DD, a cross-section scan data sample, distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV, was.t.ken with the BEsIII detector operated at the BEPCII collider in the year 2010. By analyzing the large angle Bhabha scattering events, we measure the integrated luminos.t. of the data sample at each center-of-mass energy point. the total integrated luminos.t. of the data sample is 76.16±0.04±0.61 pb^-1, where the first uncertainty is statistical and the second systematic.

there has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. this renaissance has been driven in part by the discovery of a plethora of charmonium-like x.Z states at BEsⅢ and B factories, and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related x.1835) meson state at BEsⅢ, as well as.t.e threshold measurements of charm mesons and charm baryons. We present a detailed survey of the important topics in tau-charm physics and hadron physics.t.at can be further ex.lored at BEsⅢ during the remaining operation period of BEPCⅡ. this survey will help in the optimization of the data-taking plan over the coming years, and provides physics motivation for the possible upgrade of BEPCⅡ to higher luminos.t..

Using inclusive decays of j/ψ aprecise determination of the number of j/ψ events collected with the BEsIII detector was *** the two data s.t. taken in 2009 and 2012,the numbers of j/ψ events were recalculated to be(224.0±1.3)×10^(6) and(1088.5±4.4)×10^(6),respectively;these numbers are in good agreement with the previous measurements. For the j/ψ sample taken in 2017-2019,the number of events was determined to be(8774.0±39.4)×10^(6).the total number of j/ψ events collected with the BEsIII detector was determined to be(10087±44)×10^(6),where the uncertainty is dominated by systematic effects,and the statistical uncertainty is negligible.
