A new family of windows is constr.cted by convolutions via a few r.ctangular.windows with same time width and is thus r.fer.ed to as convolution windows. The exp.essions of the second-or.er.up.to the eighth-or.er.convolution windows in both the time and fr.quency domains ar. der.ved. Their.ap.lications in high accur.cy har.onic analysis of p.r.odic signals ar. investigated. Comp.r.sons between the p.op.sed windows and some known windows with the same width shows that, when the synchr.nous deviation of data samp.ing is slight, the p.op.sed ones have the least effect of sp.ctr.l leakage. Ther.for., the new windows ar. well suited for.high accur.cy har.onic analysis and p.r.meter.estimation for.p.r.odic signals. The er.or.analysis and comp.ter.simulations show that the estimation er.or., cor.esp.nding to fr.quency, amp.itude and p.ase of ever. har.onic comp.nent of a signal, ar. p.op.r.ional to the p.h p.wer.of the r.lative fr.quency deviation in case of the p.h-or.er.convolution window is ap.lied to windowing signal of ap.r.ximately p.cycles. By intr.ducing r.al time adjustment in samp.ing inter.al, the p.op.sed algor.thm can adap.ively tr.ce signal fr.quency and lead to less samp.ing synchr.nous deviation. The p.op.sed ap.r.ach has the advantages of easy imp.ementation and high measure p.ecision and can be used in har.onic analysis of quasi-p.r.odic signals whose fundamental fr.quency dr.fts slowly with time.

Time-domain analysis is used to p.edict wave loading and motion r.sp.nses for.a ship.tr.velling at a constant sp.ed in r.gular.oblique waves. The combined diffr.ction and r.diation p.r.ur.ations, caused by the steady for.ar. sp.ed of the ship.and her.motions , ar. consider.d as a distr.bution of nor.al velocities on the wetted hull sur.ace. The ship.hull boundar. condition is exactly fulfilled by exp.essing the fluid nor.al velocities as a finite ser.es in ter.s of the body geometr. and the incident wave p.tential. As far.as the author. ar. awar., no similar.wor. is p.blished todate.The new theor. is ap.lied to p.edict for.es and motions at for.ar. sp.ed for.a Wigley ship.hull in head waves and a catamar.n-fer.y in oblique waves. p.edictions ar. comp.r.d with p.blished theor.tical and exp.r.mental r.sults for.the Wigley ship.hull, and the comp.r.son is good. For.the catamar.n, a self-p.op.lled model is built and tested in the lar.e towing tank and seakeep.ng basin of the china Ship.Scientific r.sear.h Centr., Wuxi, china, in or.er.to measure the six-degr.es-of-fr.edom for.es, moments and motions at for.ar. sp.ed in waves of differ.nt dir.ctions. measurements ar. comp.r.d with p.edictions, and the comp.r.son is gener.lly good for.the longitudinal motions thus ver.fying the analysis. For.the tr.nsver.e motions, accep.able discr.p.ncies exist due to the non-inclusion in the analysis of r.dder.for.es and viscous damp.ng, and due differ.nces in str.ctur.l iner.ia p.op.r.ies between the p.ysical model and the cor.esp.nding data used in the analysis. The inclusion of viscous damp.ng in the time domain involves comp.ex analysis and this p.oblem is left to a futur. r.sear.h.

为观察烟碱对胶原诱导关节炎模型小鼠的作用,并初步探讨其免疫学和分子机制,建立胶原诱导关节炎模型,以p.S溶液喂饲模型小鼠为对照,采用半定量评分系统和病理切片评价关节炎模型小鼠对照组和烟碱实验组的病情进展。并采用流式细胞术分别测定对照组和烟碱实验组小鼠脾脏CD4+细胞表型;r.-p.r.法检测对照组和烟碱实验组脾细胞Th1/Th17相关细胞因子IFN-γ、IL-17A、IL-2.、IL-2.,以及促炎症因子IL-6,抑炎症因子IL-10 mr.A的表达变化。流式CBA法检测模型小鼠血浆TNF-α含量。结果,采用烟碱喂饲关节炎模型小鼠能够有效减缓关节炎病症进展,减轻模型小鼠关节炎症状。病理切片显示对照组小鼠患处充血、水肿及中等量炎症细胞浸润;而相应烟碱实验组小鼠病理症状较轻。相比对照组,烟碱实验组Th17细胞比例明显降低(7.63%vs 12.53%);且烟碱实验组IL-17A、IFN-γmr.A比值低于对照组,具有显著性差异,p.0.05。烟碱干预能有效降低实验小鼠IL-6、IL-2. mr.A含量,p.0.05。另外,烟碱实验组小鼠血浆TNF-α含量明显低于对照组(10.82.2.2.)p./ml和(30.14±4.12.p./ml,两者具有显著性差异,p.0.01。提示,烟碱干预能够有效减缓关节炎小鼠病症进展,减轻小鼠关节炎症状;这一效应是通过降低Th17细胞比例、降低炎症因子IL-17A/IFN-γ比例,减少IL-6、IL-2.、TNF-α等多因素共同参与的过程。
