A sensitivity study on the measurement of the CKM angle γ from B_(s)^(0)→D^(+)^(0)Ф decays is conducted us-ing the D-meson reconstructed in the quasi flavour-specific modes Kπ,K3π,and Kππ^(0),as well as CP-eigenstate modes KK and m,where the notation DO corresponds toa D0 or D0 *** LHCb experiment is presented as a use case.A statistical uncertainty of approximately 8°-19°can be achieved with the pp collision data collcted in the LHCb experiment from 2011 to *** sensitivity to r should be of the order 3°-8°after accumulating 23 fb^(-1) of pp collision data by 2025,whereas it is expected to improve further by 300 fb^(-1) by the second half of the 2030 *** accuracy is dependent on the strong parameters r and og,which together with ydescribe the interfer-ence between the leading ampliudes of the B_(s)^(0)→D^(+)^(0)Ф decays.

采用数值模拟与工艺实验的方法,研究了双阶梯无过渡锥角管件的内高压成形过程。在总轴向进给量与进给压力均为定值条件下,研究了管端左右进给量分配比对成形结果的影响,分析了成形不同阶段管坯的形状变化与壁厚分布,以及管坯不同部位应变在成形极限图上的变化轨迹。结果表明,双阶梯管件左侧与右侧轴向进给量存在合理分配比;无过渡锥角管件易出现折叠现象;双阶梯管件可以通过起皱成形,但皱峰与皱谷的应变路径不同,壁厚变化也不同。

Frontiers in Energy 2017年第4期11卷 493-502页

作者： Bin HU Di WU L.W. wang r.z. wang Institute of refrigeration and Cryogenics Shanghai Jiao Tong University Shanghai 200240 China

In this paper, the simulation approach and exergy analysis of multi-stage compression high tempera- ture heat pump （HTHP） systems with r1234ze（z） working fluid are conducted. Both the single-stage and multi-stage compression cycles are analyzed to compare the system performance with 120℃ pressurized hot water supply based upon waste heat recovery. The exergy destruction ratios of each component for different stage compression systems are compared. The results show that the exergy loss ratios of the compressor are bigger than that of the evaporator and the condenser for the single-stage compres- sion system. The multi-stage compression system has better energy and exergy etticiencies with the increase of compression stage number. Compared with the single- stage compression system, the coefficient of performance （COP） improvements of the two-stage and three-stage compression system are 9.1% and 14.6%, respectively. When the waste heat source temperature is 60℃, the exergy efficiencies increase about 6.9% and 11.8% for the two-stage and three-stage compression system respec- tively.
