Laser heating process of materials is a complex heat transfer problem involved with laser beam, workpiece and ambience. In particular, variable convective boundary condition has great influence on temperature field distribution and processing quality. However, in the previous studies of temperature field抯 solution, convective boundary condition was either simplified or ignored which affected calculation accuracy and precision. In this paper, an analytical solution for the temperature field with convective boundary condition is obtained using Laplace transforms. Moreover, the dimensionless parameters are identified appropriately. Influence of dimensionless distance (x′), dimensionless time (t ), dimensionless energy absorption at surface (M) and Biot number (Bi) on dimensionless temperature (T′) have been investigated. The results show: as Bi is increased, the effects of the heat convection become more pronounced and make the location of the peak temperature move away from the surface. The method of thermocamera is used to validate the analytical solution for pulsed laser heating process with convective boundary condition and the ideal results are obtained. The present study provides the theoretical basis for improving the understanding of physical process, exact modelling and quality controlling of laser welding and surface treatment.

Nested-loop secondary linear doubly-fed machine(NLS-LDFM) is a novel linear machine evolved from rotary brushless doubly-fed induction machine, which has a good application prospect in linear metro. In order to analyze the performance of NLS-LDFM, the mechanism and action rules of end effects are investigated in this paper. Firstly, the mechanism of static and dynamic end effects is analyzed in aspect of direct coupling, winding asymmetry and transient secondary current. Furthermore, based on the winding theory for short primary linear machines, the machine parameters are established qualitatively considering pulsating magnetic field of NLS-LDFM. Finally, the NLS-LDFM performance analysis is supplemented by the finite element algorithm(FEA) simulation and experiments under different operating conditions.

A novel zebra mutant, zebra-15, derived from the restorer line JinhuilO （Oryza sativa L. ssp. indica） treated by EMS, displayed a distinctive zebra leaf from seedling stage to jointing stage. Its chlorophyll content decreased （55.4%） and the ratio of Chla/Chlb increased （90.2%） significantly in the yellow part of the zebra-15, compared with the wild type. Net photosynthetic rate and fluorescence kinetic parameters showed that the decrease of chlorophyll content significantly influenced the photosynthetic efficiency of the mutant. Genetic analysis of F2 segregation populations derived from the cross of XinonglA and zebra-15 indicated that the zebra leaf trait is controlled by a single recessive nuclear gene. Ninety-eight out of four hundred and eighty pairs of SSR markers showed the diversity between the XinonglA and the zebra-15, their F2 population was then used for gene mapping. Zebra-15 （Z-15） gene was primarily restricted on the short arm of chromosome 5 by 150 F2 recessive individuals, 19.6 cM from marker RM3322 and 6.0 cM from marker RM6082. Thirty-six SSR markers were newly designed in the restricted location, and the Z-15 was finally located between markers nSSR516 and nSSR502 with the physical region 258 kb by using 1,054 F2 recessive individuals.

新中国成立后,经济工作面临重重困境。陈云勇挑重担,为稳定物价、统一财经、实行统购统销、完成社会主义改造作出贡献,推动了国民经济迅速恢复和发展。能取得这样的成就,与他的全局思维是分不开的。陈云既善于运用全局思维解决经济工作中的复杂难题,也善于运用全局思维处理好经济工作中的各种关系。他还要求经济工作者树立全局思维,避免陷于局部观点和本位主义。陈云从全局高度、用长远眼光观察形势、分析问题的思维方法,在新时代仍具有现实意义。

在社会主义条件下,一切非异化的劳动都应该得到充分的尊重。为此,必须从思想认同、道义认同、法律认同以及道德认同四个方面着手,形成一整套制度和社会氛围。具体而言,因劳称义、劳动权利和生命价值是社会主义最基本的劳动法则。为了贯彻尊重劳动的这三大法则,必须坚守"身份勿先定"等十五条劳动道义。同时,还必须从各个层次的法律体系上进行系统设计。从法律认同来说,最高层次法律必须对三大法则有明确的主张;具体的专门法律应该对劳动道义有系统主张;其他各种法律也要对基本法则和劳动道义加以全面维护;并且,要努力使社会全部规范对基本法则和劳动道义进行竭力宣扬。最后,从道德认同尊重劳动这一核心价值主张来说,人人践行植根于劳动的坚韧果敢精神,树立天职观念,恪尽职守,遵信守时,个体独立地自我创造,通过劳动展现合作与分享的团队精神,以及合理追求劳动幸福,厉行勤俭节约并珍惜劳动成果等,便成为最基本的劳动美德观念。

有史以来,民间信仰仪式及其音乐就是少数民族最为重要的音声表达形式。从基本概念看,民间信仰仪式音乐涵括信仰、仪式和音乐三个不可或缺的文化体系。就音乐分类而言,迄今尚属“空白”,因而笔者初步将其分归为:自然崇拜、植物崇拜、天体崇拜、图腾崇拜、万物有灵、祖先崇拜、鬼神崇拜、消灾与禳解、巫术与占卜九个类别。本文从民间信仰仪式音乐存续方式与表达形式将其分归为声乐、器乐、舞乐三个既独立又关联的部分,认为中国少数民族民间信仰仪式音乐具有鲜明的地域特色与多样性,但也有一些基本规律可循。
