Based on the analysis of its basic characteristics, this article investigated the disparities of Chinese service industry among the three regions （the eastern China, the western China and the middle China） and inter-provincial disparities of that in the three regions by Theil coefficient and cluster analysis. Then, major factors influencing its spatial disparity were explored by correlation analysis and regression analysis. The conclusions could be drawn as follows. 1） The development of Chinese service industry experienced three phases since the 1980s： rapid growth period, slow growth period, and recovery period. From the proportion of value-added and employment, its development was obviously on the low level. From the composition of industrial structure, traditional service sectors were dominant, but modem service sectors were lagged. Moreover, its spatial disparity was distinct. 2） The level of Chinese service industry was divided into five basic regional ranks： well-developed, developed, relatively-developed, underdeveloped and undeveloped regions, As a whole, the overall structure of spatial disparity was steady in 1990-2005. But there was notable gradient disparity in the interior structure of service industry among different provinces. Furthermore, the overall disparity expanded rapidly in 1990-2005. The inter-provincial disparity of service industry in the three regions, especially in the eastern China, was bigger than the disparity among the three regions. And 3） the level of economic development, the level of urban development, the scale of market capacity, the level of transportation and telecommunication, and the abundance of human resources were major factors influencing the development of Chinese service industry.

对于无铁心动铁式长行程直线电机,其动子Halbach永磁阵列长度小于定子线圈沿运动方向的长度,为线圈切换简单及提高磁场的利用率,使得通电线圈范围大于永磁阵列产生的磁场范围,此时通电线圈数目不发生变化,需利用到永磁阵列的端部磁场。由于端部磁场的畸变产生端部效应,引起的推力波动将影响电机的运动精度。为此,需要建立准确的包含端部效应的Halbach永磁阵列磁场模型。以无铁心动铁式永磁同步直线电机为研究对象,考虑端部效应,采用修正的傅里叶级数形式推导出了伪周期内完整的Halbach永磁阵列磁场解析模型,并利用Maxwell应力张量法建立了电机推力模型。通过磁场有限元仿真、推力测试,对比结果验证了所提方法的准确性和有效性。

对于无铁芯动铁式长行程平面电机,其动子Halbach永磁阵列端部磁场的畸变将产生端部效应,由其引起的推力波动将影响平面电机定位与运动精度。建立准确的包含端部磁场的Halbach永磁阵列三维磁场数学解析模型,是电机推力建模、避免推力波动、提高端部磁场利用率及降低单个线圈能耗的基础。以无铁芯动铁式永磁同步平面电机动子Halbach永磁阵列为研究对象,分析了Halbach永磁阵列中磁场类正弦区与端部畸变区的磁场特性,通过将Halbach永磁阵列外边缘磁场衰减至零的特征边界间距定义为机械伪周期,并采用新的傅立叶级数及空间积分技术,推导出了完整的Halbach永磁阵列全空间磁场三维数学解析表达式。通过与有限元计算及现有磁场解析计算方法的对比,结果验证了提出的磁场建模方法的准确有效性。

思政课作为落实立德树人根本任务的关键课程,具有覆盖大中小学学习全过程、融入大中小学学生生活全领域等特性,在学生的成长成才过程中发挥着不可替代的作用。但长期以来,思政课在育人过程中却存在诸如学段间、课程间内容过度重复衔接性不高,大中小学教师"各管一段"、"背靠背"教学,中小学思政课教师不顾后、大学思政课教师不瞻前等问题,忽视了思想政治教育的整体性、连贯性,无法实现思想政治理论课教学的总体目标。面对世界百年未有之大变局,思政课建设必须站在为党育人、为国育才的高度,统筹推进大中小学思政课一体化建设,厘清各学段的课程目标,明确不同学段教材的难易度和区分度,根据学生成长规律推进大中小学思政课教学内容兼顾交融,搭建平台,为实现大中小学思政课教育教学三个层级的循序渐进和有效衔接,提供相应的政策指引及体制保障。
