This paper presents an analy.is of the conditions of stability.of the different forms of internal oxidation of ideal ternary.A-B-C alloy.,where A is the most noble and C the most reactive component, forming insoluble oxide and exposed to high pressures of a single *** treatment,based on an extension to ternary.alloy. of Wagner' s criterion for the transition from internal to external oxidation in binary.alloy.,allows to predict the existence of three different forms of internal *** fact,in addition to the most common kinds of internal attack,involving the coupled internal oxidation of B+C beneath external AO scales and the internal oxidation of C beneath external BO scales,a third mode, involving the internal oxidation of C beneath external scales composed of mixtures of AO+BO,becomes also possible under special conditions.A combination of the boundary.conditions for the existence of these different ty.es of internal oxidation allows to predict three different kinds of complete maps for the internal oxidation in these sy.tems,one of which involves only.two modes,while the other two involve all the three possible modes of internal oxidation.

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 taken with the BESIII detector operated at the BEPCII collider in the y.ar 2010. By.analy.ing the large angle Bhabha scattering events, we measure the integrated luminosity.of the data sample at each center-of-mass energy.point. The total integrated luminosity.of the data sample is 76.16±0.04±0.61 pb^-1, where the first uncertainty.is statistical and the second sy.tematic.

Water wave energy.exhibits great potential toalleviate the global energy.crisis. However, harvesting andutilizing wave energy.are challenging due to its irregularity.randomness, and low frequency. Triboelectric nanogenerators(TENGs) have gained significant attention for harvesting waveenergy.with high efficiency. This study.presents a novelellipsoidal, pendulum-like TENG integrating both liquid-liquid(L-L) and solid-solid (S-S) triboelectricity.(LS-TENG). Thisinnovative design enables continuous wave energy.harvestingand self-powered marine environment monitoring under variousconditions, including temperature, humidity. and light intensity. The binary.immiscible liquids within the LS-TENG’s innersoft balloon create dy.amic, and self-adjustable L-L contact interfaces, significantly.increasing the L-L contact area andenhancing L-L contact electrification (CE). The unique self-adaptive, soft S-S contact increases the S-S contact areacompared to traditional hard point contact, better adapting to the irregular movements of waves and promoting efficient S-SCE. The LS-TENG achieves highly.efficient wave energy.harvesting by.coupling L-L and S-S CE. Furthermore, the uniquesoft contact design protects the S-S interfaces from mechanical wear and damage during long-term work. The LS-TENG’snovel structure provides an innovative and effective way.for water wave energy.harvesting.
