Ammon.a is gain.n. in.reasin. atten.ion.as a green.altern.tive fuel for achievin. large-scale carbon.emission.reduction. Despite its poten.ial techn.cal prospects, the harsh ign.tion.con.ition. an. slow flame propagation.speed of ammon.a pose sign.fican. challen.es to its application.in.en.in.s. n.n.equilibrium plasma has been.iden.ified as a promisin. method, but curren. research on.plasma-en.an.ed ammon.a combustion.is limited an. primarily focuses on.ign.tion.characteristics revealed by kin.tic models. In.this study, low-temperature an. low-pressure chemistry in.plasma-assisted ammon.a oxidative pyrolysis is in.estigated by in.egrated studies of steady-state GC measuremen.s an. mathematical simulation. The detailed kin.tic mechan.sm of n.3decomposition.in.plasma-driven.Ar/n.3an. Ar/n.3/O2mixtures has been.developed. The n.merical model has good agreemen.s with the experimen.al measuremen.s in.n.3/O2con.umption.an. n./H2gen.ration. which demon.trates the ration.lity of modellin.. Based on.the modellin. results, species den.ity profiles, path flux an. sen.itivity an.lysis for the key plasmaproduced species such as n.2, n., H2, OH, H, O, O（1D）, O2（a1△g）, O2（b1∑g+）, Ar*, H-, Ar+, n.3+, O2-in.the discharge an. afterglow are an.lyzed in.detail to illustrate the effectiven.ss of the active species on.n.3excitation.an. decomposition.at low temperature an. relatively higher E/n.values. The results revealed that n.2, n., H as well as H2are primarily gen.rated through the electron.collision.reaction. e + n.3→ e + n.2+ H, e + n.3→ e + n. + H2an. the excited-argon.collision.reaction.Ar*+ n.3+ H → Ar + n.2+ 2H, which will then.react with highly reactive oxidative species such as O2*, O*, O, OH, an. O2to produce stable products of n.x an. H2O. n.3→ n. is foun. a specific pathway for n.3con.umption.with plasma assistan.e, which further highlights the en.an.ed kin.tic effects.

Reliable calculation. of n.clear bin.in. en.rgies by the Gaussian.process of machin. learn.n.

引用

作者： Zi-Yi Yuan.Don. Bai Zhen.Wan. Zhon.-zhou Ren School of Physics Scien.e an. En.in.erin. Tongji UniversityShanghai 200092China College of Scien.e Hohai UniversityNanjing 211100China Key Laboratory of Advan.ed Micro-Structure Materials Ministry of EducationShanghai 200092China

Reliable calculation. of n.clear bin.in. en.rgies are crucial for advan.in. the research of n.clear physics. Machin. learn.n. provides an.in.ovative approach to explorin. complex physical problems. In.this study, the n.clear bin.in. en.rgies are modeled directly usin. a machin.-learn.n. method called the Gaussian.process. First, the bin.in. en.rgies for 2238 n.clei with Z > 20 an. n.> 20 are calculated usin. the Gaussian.process in.a physically motivated feature space, yieldin. an.average deviation.of 0.046 MeV an. a stan.ard deviation.of 0.066 MeV. The results show the good learn.n. ability of the Gaussian.process in.the studies of bin.in. en.rgies. Then. the predictive power of the Gaussian.process is studied by calculatin. the bin.in. en.rgies for 108 n.clei n.wly in.luded in.AME2020. The theoretical results are in.good agreemen. with the experimen.al data, reflectin. the good predictive power of the Gaussian.process. Moreover, the α-decay en.rgies for 1169 n.clei with 50 ≤ Z ≤ 110 are derived from the theoretical bin.in. en.rgies calculated usin. the Gaussian.process. The average deviation.an. the stan.ard deviation.are, respectively, 0.047 MeV an. 0.070 MeV. n.ticeably, the calculated α-decay en.rgies for the two n.w isotopes ^ (204 )Ac(Huan. et al. Phys Lett B 834, 137484(2022)) an. ^ (207) Th(Yan. et al. Phys Rev C 105, L051302(2022)) agree well with the latest experimen.al data. These results demon.trate that the Gaussian.process is reliable for the calculation. of n.clear bin.in. en.rgies. Fin.lly, the α-decay properties of some un.n.wn.actin.de n.clei are predicted usin. the Gaussian.process. The predicted results can.be useful guides for future research on.bin.in. en.rgies an. α-decay properties.
