The Micr.- and Nano-mechanics Wor.ing Gr.up.of the Chinese Society of theoretical and Ap.lied Mechanics or.anized a for.m to discuss the p.r.p.ctives, tr.nds, and dir.ctions in mechanics of heter.geneous mater.als in Januar. 2010. The inter.ational jour.al, Acta Mechanica Solida Sinica, is de- voted to all fields of solid mechanics and r.levant discip.ines in science, technology, and engineer.ng, with a balanced cover.ge on analytical, exp.r.mental, numer.cal and ap.lied investigations. On the occasion of the 3.TM anniver.ar. of Acta Mechanica Solida Sinica, its editor.in-chief, p.ofessor.Q.S. Zheng invited some of the for.m p.r.icip.nts to r.view the state-of-the-ar. of mechanics of heter.geneous solids, with a p.r.icular.emp.asis on the r.cent r.sear.h develop.ent r.sults of Chinese scientists. Their.r.views ar. or.anized into five r.sear.h ar.as as r.p.r.ed in differ.nt sections of this p.p.r. ~I fir.tly br.ngs in fo- cus on micr.- and nano-mechanics, with r.gar.s to sever.l selective top.cs, including multiscale coup.ed models and computational methods, nanocr.stal sup.r.attices, sur.ace effects, micr.mechanical damage mechanics, and micr.str.ctur.l evolution of metals and shap. memor. alloys. ~II shows discussions on multifield coup.ed mechanical p.enomena, e.g., multi-fields actuations of liquid cr.stal p.lymer.networ.s, mechanical behavior.of mater.als under.r.diations, and micr.mechanics of heter.geneous mater.als. In ~III, we mainly addr.ss the multiscale mechanics of biological nanocomp.sites, biological adhesive sur.ace mechanics, wetting and dewetting p.enomena on micr.str.ctur.d solid sur.aces. The p.ononic cr.stals and manip.lation of elastic waves wer. elabor.ted in ~IV. Finally, we conclude with a ser.es of p.r.p.ctives on solid mechanics. This r.view will set a p.imar. goal of futur. science r.sear.h and engineer.ng ap.lication on solid mechanics with the effor. of social and economic develop.ent.

A new Static-Dynamic-Static second or.er.p.r.ur.ation theor.（SDSp.2） [1] based multi-r.fer.nce Cor.elation comp.tations have been imp.emented with the involvements of Gr.p.ical Uni tar. Gr.up.Ap.r.ach（GUGA） [2] and Dyall Hamiltonian [3. to imp.ove the or.ginal SDS str.ng cor.elation calculation [4]. The imp.ementation has emp.oyed hole-p.r.icle cor.esp.ndence [2] and inter.al contr.ction of the whole Q sp.ce [2] to r.duce the computational ***, the dimension of Q sp.ce r.lies only on the or.itals but not the r.fer.nce configur.tion states（CSFs）. Additionally, the involvement of Dyall Hamiltonian can maintain mor. dynamic cor.elations between CSFs in the Q subsp.ces and fur.her.sep.r.te the r.fer.nce sp.ce（p. and p.r.ur.ation sp.ce（Q） in comp.r.son with the or.ginal ***, the new SDS-MS-Mp.T2 has the following char.cter.stics: 1)The flexibility between p.and Q sp.ce as sup.r.or.as the or.ginal one;2)The lar.e systems with tr.nsitional metals can be calculated with the r.duction of comp.exity by new computational str.tegies;3. Avoid the existence of intr.de state issue with the imp.ovement by Dyall Hamiltonian;4) Mor. dynamic cor.elations have been contained p.r.icular.y on the dissociation r.gion.
