More than ten Triassic syenite plutons are revealed to be distributed in North korea along the boundary to south *** Tokdal Complex is one of these but is unique in its incorporation of early pyroxenite cumulate in the clinopyroxene/amphibole/biotite/nepheline-bearing syenite main body.A SHRIMP U-Pb zircon age of 224±4 Ma was obtained from a biotite syenite sample. Clinopyroxene in pyroxenite is zoned,with either phlogopite and apatite inclusion or ilmenite and magnetite exsolution,and may have resulted from crystallization at high pressure in an active continental margin arc environment followed by ascent and *** pyroxenite and syenite are enriched in light REE and LILE,but strongly depleted in HFSE,with Sr/860Sr values of～0.7115 andεNd values of -14 to -20(t = 224 Ma).The Tokdal Complex could have originated from an enriched lithospheric mantle and undergone assimilation of juvenile materials during differentiation. It indicates an extension of post-collisional magmatism in the Sino-korean *** complex along with many other Triassic plutons in the Sino-korean craton together constitute three syenite belts along the northern,southern and eastern margins of the craton,possibly resulting in its final configuration in eastern Asia.

Considerable debate on whether and how the Sulu Orogenic Belt extends eastward to the korean Peninsula has remained over the past decade. New results reported here include the following:(1) an eclogite and retrograded eclogite-bearing complex(Hongseong Complex) is discovered in south korea,in which the eclogite occurs as lenses in circa～810-820 Ma granitic *** zircon dating of the eclogite yields～230 Ma for the metamorphic age and～880 Ma for the protolith age;(2) The basement of the Rangnim,Gyeonggi and Yeongnam massifs have affinities to, the basement of the North China Block(NCB).However the Gyeonggi Massif encloses a minor amount of large or small slabs of the Hongseong Complex that are similar to the rocks of the Sulu Belt.(3) Two main Paleozoic basins within the Rangnim and Gyeonggi massifs have a similar Paleozoic tectono-stratigraphy to the NCB.(4) The Imjingang and Ogcheon belts do not exhibit any metamorphic characteristics of collisional orogenic *** on these facts,we propose a crustal-detachment and thrust model and suggest that the collision belt between the Yangtze Block(YB) and NCB(Sino-korea Craton) is preserved along the western margin of the korean *** lower part of the UHP metamorphosed lithosphere of the YB was subducted under the korean Peninsula and not uplifted to the *** lower crust of the YB(the Hongseong Complex) was detached from the subducted lithosphere and thrust over the korean Peninsula,and inserted into the basement rocks of the Gyeonggi *** upper crust of the YB possibly was detached from the lower crust and overthrusted along the Honam and Chugaryong shear *** Imjingang and Ogcheon belts possibly represent the detached upper crust of YB and their present occurrences are controlled by a Mesozoic strike-slip shear *** these detached lower and upper crustal slabs were strongly deformed during the Late Jurassic and Early Cretaceous tectonic event leading to their present geologi

将零维(0 D) Si 69改性的二氧化硅纳米颗粒(MS)和KH 550官能化的二维(2 D)多层氧化石墨烯(KGO)组成的纳米复合物通过胶乳法制备了天然橡胶(NR)纳米材料,研究了纳米材料的多尺度增强和界面强化。结果表明,通过MS和KGO表面活性极性官能团之间良好的H键相互作用形成了0 D/2 D杂化复合物(即MSKGO),后者与异戊二烯单元通过Si 69的硫化物相互作用和非极性相互作用与氧化石墨烯(GO)形成NRMSKGO的三维网络结构;在干燥和固化过程中,H键网络结构转化为共价键网络结构,同时GO部分转变为还原氧化石墨烯(RGO)。含有质量分数为3%GO的复合材料的200%定伸应力和拉伸强度分别提高9. 47倍和1. 36倍;仅使用10份含质量分数1%GO的复合材料替代10份NR制备的轮胎胎面,不仅使炭黑降低5份,且耐磨性和抗湿滑性分别提高了44. 5%和14. 6%,滚动阻力下降了5. 1%

The decay channel ψ′→ π 〉＋π^-J/ψ（J/ψ 〉 γp^-p） is studied using a sample of 1.06 × 10^8 ψ′ events collected by the BESIII experiment at BEPCII. A strong enhancement at threshold is observed in the p^-p invariant mass spectrum. The enhancement can be fitted with an S-wave Breit-Wigner resonance function with a resulting peak mass of M = 1861-13^＋6 （stat）-26^＋7 （syst） MeV/c^2 and a narrow width that is Г 〈 38 MeV/c^2 at the 90% confidence level. These results are consistent with published BESII results. These mass and width values do not match with well established mesons.
