摘要：(一)在描写了鲁镇的人们都在准备着年终祝福的情形之后,作者加了几句注释性的话:“年年如此,家家如此,——只要买得起福礼和爆竹之类的,——今年自然也如此。”——这几句看起来像是赘笔,删去可以吗?[加上这几句注释性的话,是有深意的。它从时间范围(年年)和空间范围(家家)

摘要：近年来,我国城市经济的形成与发展,不断推动着城市基础设施建设、文化旅游、餐饮服务、交通通讯等行业繁荣发展,同时也给媒体行业带来难得的发展机遇。互联网的崛起和新媒体的不断涌现,使得城市媒体的发展空间得到拓展,受众的注意力则变得日趋分散,媒介环境比以往任何时代都更加复杂。在城市空间范围内,一个城市的经济及综合实力,关系到受众生活和传媒基础设施的建设,同时塑造了差异化的受众媒介接触环境和形态,从而产生分级城市间受众媒介接触行为的差异。

摘要：Sampling design(SD) plays a crucial role in providing reliable input for digital soil mapping(DSM) and increasing its *** design, with a predetermined sample size and consideration of budget and spatial variability, is a selection procedure for identifying a set of sample locations spread over a geographical space or with a good feature space coverage. A good feature space coverage ensures accurate estimation of regression parameters, while spatial coverage contributes to effective spatial ***, we review several statistical and geometric SDs that mainly optimize the sampling pattern in a geographical space and illustrate the strengths and weaknesses of these SDs by considering spatial coverage, simplicity, accuracy, and efficiency. Furthermore, Latin hypercube sampling, which obtains a full representation of multivariate distribution in geographical space, is described in detail for its development, improvement, and application. In addition, we discuss the fuzzy k-means sampling, response surface sampling, and Kennard-Stone sampling, which optimize sampling patterns in a feature space. We then discuss some practical applications that are mainly addressed by the conditioned Latin hypercube sampling with the flexibility and feasibility of adding multiple optimization criteria. We also discuss different methods of validation, an important stage of DSM, and conclude that an independent dataset selected from the probability sampling is superior for its free model assumptions. For future work, we recommend: 1) exploring SDs with both good spatial coverage and feature space coverage; 2) uncovering the real impacts of an SD on the integral DSM procedure;and 3) testing the feasibility and contribution of SDs in three-dimensional(3 D) DSM with variability for multiple layers.

摘要：“世界”．真是一个值得玩味的词。它是在人类词汇中除了“宇宙”之外表述空间范围概念的第二大词汇了。但是宇宙的使用量太少．它所包含的内容多与地球无关：而“世界”则不同．它最小的概念所指也与地球本身及人、自然山川有关。如世界的第一解即是全球：第二解即是地区．如阿拉伯世界，第三世界等等：第三解即是种类性质．如动物世界，自然界，生物界，人类世界等等：第四解即是区别范围性质的称谓．如内心世界，宏观世界、微观世界等等。

摘要：Three kinds of possible structures of legged lander including monocoqe, semi-monocoqe and space frame are compared, and the lightest space frame structure is selected as the lander's structure. Then, a new lander with four-legged truss structure is proposed. In the premise of ensuring that the main and assistant structures of landing legs are not changed, six possible lander body structures of the new lander are put forward. Taking the section size of each component of lander as design variables, and taking the total mass of the structure as the objective function, the six structures are analyzed by using the software Altair. OptiStruct and the results show that the mass of the basic structure is the lightest, and it is selected as the final design scheme of lander due to its simple structure and convenient manufacture. The optimization on the selected lander structure is conducted, and the detailed results are presented.

摘要：设计了一种近场聚焦直线阵列天线,并从电磁波中的干涉角度实现在近场范围内的空间聚焦,通过验证并分析了这种阵列天线的空间范围内的聚焦情况.实验从电磁波的干涉角度出发,首先让频率为2450 MHz,波长为12.45 cm的微波,通过一个内衬有可以吸收和防止微波扩散的金属网的波导管,测量波导管内的电磁波在没有圆形反射片的阻挡情况下传输情况.在得知了电磁波在波导管中的传输情况后,根据分析的位置放置圆形反射片.并确定圆形反射片的位置,再根据圆形反射片的透过情况确定反射片偏转的最佳角度.最后测量在长120 cm、宽50 cm,高20 cm空间范围内的聚焦分布情况.通过测量并分析可知利用干涉聚焦的方法设计的近场聚焦直线阵列天线在进场空间范围内取得了很好的聚焦效果.

摘要：在狭小的空间范围内如何能实现既有富有灵气的水池又有娱乐的空间呢?这要求设计师必须充分利用每一寸可用的空间,做到麻雀虽小五脏俱全。应该说这不只是一座闲情逸趣的花草园,更是一座结合了大自然情调与时尚精神的异想空间,一座城市里的绿洲。让人身处其中,乐不思蜀。

摘要：1.构图形式的影响 人们一般所说的西洋绘画,是对欧洲和美国等西方国家绘画的统称,它包括有油画、水彩画、水粉画、素描、珐琅玻璃画,等多种艺术形式。构图，从广义上讲，是指形象或符号对空间占有的状况。狭义上讲，构图是画家为了表现一定的思想、意境、情感，在一定的空间范围内，运用审美的原则安排和处理形象、符号的位置关系，

摘要：在人类的历史发展过程中，美丽的环境是人们无时无刻都在追求的目标。最早的造园造诣可以追溯到二千多年祭奠神灵的场地、供帝王贵族狩猎游乐的场地和居民为改善环境而进行的绿化栽植等。初期的园林主要是植物与建筑物的相结合，园林造型比较简单，建筑物是主体，园林仅充当建筑物的附属品。随着社会的发展，园林逐渐摆脱建筑的束缚，园林的范围也不仅局限于庭园、庄园、别墅等单个相对独立的空间范围，而是扩大到城市环境、风景区、保护区、大地景观等区域，涉及人类的各种生存空间。
