With an ever increas.ng energy demand and environmental is.ues. many s.ate-of-the-art nanos.ructured electrode materials.have been develop.d for energy s.orage devices.and they include batteries. s.p.rcap.citors.and fuel cells. Among thes. electrode materials. L-TMD （layered trans.tion metal dichalcogenide） nanos.eets.（es.0}cially, s.（s.lfur） and s. （s.lenium） bas.d dichaleogenides. have received a lot of attention due to their intriguing layered s.ructure for enhanced electrochemical p.op.rties. L-TMD comp.s.tes.have recently been inves.igated not only as.a main charge s.orage s.0}cie but als., as.a s.bs.rate to hold the active s.0}cie. This.review highlights.the recent advancements.in L-TMD comp.s.tes.with 0D （0-dimens.onal）, 1 D, 2D, 3D and various.forms.of carbon s.ructures.and their p.tential ap.lications.in LIB （lithium ion battery） and s.B （s.dium ion battery）.

Background： Circulating endometrial cells.（CECs. have been rep.rted to be p.es.nt in the p.rip.eral blood of women with endometrios.s.（EM）, p.oviding clear and s.0}cific evidence of the p.es.nce of ectop.c les.ons. In this.s.udy, we es.ablis.ed a method with a high detection rate of CECs. as.es.ed the diagnos.ic value of CECs.for EM and comp.red with s.rum CA125, and p.op.s.d a hyp.thes.s.for the p.thogenes.s.of EM from the new p.rs.0}ctive of CECs. Methods. The p.rticip.nts.were enrolled p.os.0}ctively from October 2015 to July 2016. The p.rip.eral blood s.mp.es.were collected from 59 p.rticip.nts. and the blood cells.were is.lated for immunofluores.ence s.aining via microfluidic chip.. The cells.that were p.s.tive for vimentin/cytokeratin and es.rogen/p.oges.erone recep.or and negative for CD45 were identified as.CECs. The s.rum CA125 level was.tes.ed with electrochemilumines.ence immunoas.ay. Res.lts. The detection rate of CECs.reached 89.5% （17/19） in the EM group. which was.s.gnificantly higher than that of the control group.（15.0% [6/40], p.〈 0.001） and was.indep.ndent of mens.rual cycle p.as.s. Furthermore, a p.s.tive CEC as.ay detected 4/5 cas.s.of s.age Ⅰ–Ⅱ EM. In contras., a p.s.tive CA125 tes. had limited value in detecting EM （13/19, 68.4%） and detected only one cas. of s.age Ⅰ–Ⅱ EM. Conclus.on： CECs.are p.omis.ng biomarkers.for EM with great p.tential for a noninvas.ve diagnos.ic as.ay.

利用多体动力学分析软件对某国产轿车的动力学特性进行仿真。首先建立了包含前后悬架系统、转向系统以及轮胎的整车模型,并对与整车性能影响最大的悬架系统进行模拟测试和优化修改,从而提高车辆的操作稳定性和平顺性。最后用频率正弦扫描的方法测试了整车模型的动力学特性。仿真结果显示,该车辆模型具有转向不足的特性,同时平顺性能也比较理想。用频率扫描仿真方法可以简单快速地获得车辆的整体模态特性,避免了随机振动分析方法要考虑随机振动信号的不确定性,为分析车辆动态特性提供了一种快速便捷的方法。
