This paper is entitled "Garden of Nanning days Han Xin home interior design."
Subject purpose and significance of the residential space framework,functional area,improving the overall style and design,it should be passed on space,form,details,color,works of art to carry out a comprehensive overall design to meet the different functions of the use of ,But also with a specific art form reflected the aesthetic value.And at another level pay more attention to whether the domestic environment to meet the psychological needs.
A successful indoor environment to create,requires in-depth understanding and a master indoor ring,the main habitat,and these factors scientific,artistic,human design,with appropriate language,in a limited space to create functional Mutual coordination and personalized comfortable environment,meet people of interior space in the functional,psychological and cultural aspects of the demand.
The improvement of living standards,people living on the demand from the basic physiological needs
On the needs of their living from the basic physiological needs gradually to meet the psychological and cultural fields of promoting a higher level of residential living is not the function of residential design in general,tend to focus on consideration of the function of living is generally satisfied,the function Reasonable distribution and effective use of the area,the domestic economy.In a variety of residential design style,tenants need to think more about the multi-layered psychological needs.

Ancient architecture to wood,tile-like building materials,wood for the main structural framework of the structure of this structure,the sources,beams,Shun cross-beam construction,and other major components from various components between nodes coincide with tenon and mortise d,a flexible framework.Chinese ancient wooden framework has asked Liang,Chuandou,wells dry three different structures.If style is huge stakes Liang Liang,Liang river also houses,so called "feel Liang-style." Palace,Tanmiao,monasteries and other large buildings often use such structures.Chuandou-wear Santalum album is a link to Row after row of pillars wearing a rack,particularly in Santalum album,the cross-beam to which the Big Dipper,it is called Chuandou ceremony.More for residential and smaller buildings.Wells dry-wood is used by cross-stacking,because the Circuit into space may wells and 得名.This simple structure is the original,now with the exception of a few areas of forest have been rarely used.There are many advantages of wood framework structures,first of all,load-bearing wall structure with a clear division of labour,by the wooden framework to bear the weight of the roof,the external walls of sun,insulation winterization role walls of separation indoor space.The walls are not load-bearing,which gives the structure of buildings with great flexibility.Secondly,for earthquakes,earthquake,wooden framework structure is similar to the framework today,because of the characteristics of wood,and the structure of the framework used by craftsmen and tenon and mortise d also have some latitude,and therefore to a certain extent this can be reduced by the earthquake hazards posed framework."wall would not collapse estate" vividly conveyed this structural characteristics.

解析：静力学公式,由ΣMc（F）＝0；得FBy×2a－Fp×0＝0,解得FBy＝0
其中：Mc（F）表示对C点取距；Fp×0,0是Fp的力臂

模板量的大小取决于每层的模板沾灰面积,有的框架结构可能少一点,如果短肢剪力墙的相对多一点,每层的模板含量除以建筑面积得比例.

没见过日本建筑,听说是木结构房屋居多,因为那里地震频繁,木结构的抗震性能好

不是啊,二力杆是只有两端受力的,这个中间有个交点E,还会给个力的作用
二力杆之所以叫二力杆,就是只受到两个力的作用,如果两端的力的方向不沿杆的方向,那么就会使杆旋转,直至平衡位置,所以二力杆的两端受力方向肯定是沿着杆的

主要写一下主要的工作内容,强调安全的重要性，取得的成绩，以及不足，最后提出合理化的建议或者新的努力方向。。。。。。。工作总结就是让上级知道你有什么贡献，体现你的工作价值所在。所以应该写好几点：1、你对岗位和工作上的认识2、具体你做了什么事3、你如何用心工作，哪些事情是你动脑子去解决的。就算没什么，也要写一些有难度的问题，你如何通过努力解决了4、以后工作中你还需提高哪些能力或充实哪些知识5、上级喜欢主动工作的人。你分内的事情都要有所准备，即事前准备工作。以下供你参考：总结，就是把一个时间段的情况进行一次全面系统的总评价、总分析，分析成绩、不足、经验等。总结是应用写作的一种，是对已经做过的工作进行理性的思考。总结的基本要求1．总结必须有情况的概述和叙述，有的比较简单，有的比较详细。2．成绩和缺点。这是总结的主要内容。总结的目的就是要肯定成绩，找出缺点。成绩有哪些，有多大，表现在哪些方面，是怎样取得的；缺点有多少，表现在哪些方面，是怎样产生的，都应写清楚。3．经验和教训。为了便于今后工作，必须对以前的工作经验和教训进行分析、研究、概括，并形成理论知识。总结的注意事项： 　　1．一定要实事求是，成绩基本不夸大，缺点基本不缩小。这是分析、得出教训的基础。 　 　2．条理要清楚。语句通顺，容易理解。3．要详略适宜。有重要的，有次要的，写作时要突出重点。总结中的问题要有主次、详略之分。总结的基本格式：　1、标题 　　2、正文 　 　开头：概述情况，总体评价；提纲挈领，总括全文。 　　主体：分析成绩缺憾，总结经验教训。 　　结尾：分析问题，明确方向。 　 　3、落款 　　署名与日期

C处受力Fc竖直向上,由系统平衡,B处受力FB竖直向下（即FBx=0）,FB=Fc且以B为矩心,M=Fc*2a,故FB=M/2a.
对AC杆,FE方向竖直,以A为矩心,可得FE=2Fc=M/a,向下.AC杆平衡可得FA=FC,竖直向上.AB杆平衡得FD=2FC,竖直向上. （过程中涉及作用力与反作用力未详细说明）

1维时间与3维空间构成4维时空,说白了就是四个坐标,以前的人类只用3个坐标表示位置,1个坐标表示时间,坐标系变换只变换空间的3个坐标,而4维时空的坐标系变换是时间和空间一起变换,说白了你可以把时间看成一个空间坐标,就是说空间与时间分不开了,是一个整体.

太阳升起大概方向是东边所以不能完全以这个来看.夏半年太阳东北升西北落,冬半年东南升西南落.白天要看方向最好用手表.以当地时间的时针指向太阳,时针于12时夹角(锐角)的角平分线就是正南方.
