The Cu-24 Pb-x sn(wt%)(x=0,2,4,6)alloys with Pb-rich second-phase particles(sPPs)in different shapes show obviously differently mechanical and self-lubricating *** influence of the sPPs’shape difference on the alloys’mechanical and self-lubricating properties was ***-24 Pb alloy with continuously netty sPPs shows much more intensive stick-slip phenomenon during dry sliding than the other three alloys with independently rodlike *** is mainly due to insufficient lubrication resulted by the netty sPPs’splitting *** the sPPs transforming from netty to rodlike shape under the addition of sn,the stick-slip phenomenon was notably weakened,which was proven to be related to the higher self-lubricating property of alloys with rodlike ***,the simultaneous increase of ductility and tensile strength was observed in the Cu-24 Pb-x sn alloys with increasing sn content,which is because the netty sPPs’splitting behavior will be weakened with them replaced by the rodlike sPPs.

1 IntroductionIn this talk,we briefly introduce our recent work[1] on a simple phase spacediscrete version of the symplectic algorithm[2],[3].It is well known that thesymplectic algorithm is very powerful and successful for hamiltonian systemsin comparison with other various non-symplectic computational schemes due tothe symplectic schemes are structure preserving in certain geometrical *** is well known however in the symplectic algorithm the symplectic struc-tures of phase-spaces of the problems being preserved are always taken as theoriginal continuous *** other wards,the ordinary symplectic schemescomplitely ignore the tiny-discretization properties of the phase spaces due to

Motivated by the recent experimental results of branching fractions for D^(+)_(s)→η^(′)l+v_(l) decays,which deviate from their sM predictions,we hve investigated these decays in W' model and scalar leptoquark model to determine potential signatures of new physics(NP) in semileptonic charm decays induced by c→(s,d)l+v_(l) *** recent experimental results of branching fractions for semileptonic D meson decays,new coupling parameters are predicted for the aforementioned NP *** fraction,forward-backward asymmetry,and lepton polarization asymmetry are examined by considering the predicted NP coupling *** results of branching fractions in scalar leptoquark model are found very close to the experimental results and exist around the range of 1σ *** presented a comparative study of the NP models to check their sensitivity on these *** anticipate that further research on these decays will significantly support our findings.
