wall bars

During the application of cold-rolled and twisted bars,not only should it pledge bars'strength and ductility,but also it should fulfill requirements of bars'standard thickness and panel length.

冷轧扭钢筋在应用中除应保证其强度、延性外，还应满足标准规定的厚度和节距要求。

For canvases over 40", it is best to brace the back or corners, if not using heavy duty stretchers. A major brand for stretcher bars is Fredrix, and these are sold in art stores and some office supply stores. If you are handy with saws, you can make your own stretchers with wood from the lumber yard, a piece of curved molding, and a mitre saw. Me, I'd rather spend my time painting, so I buy pre-made stretchers. You also will need "keys for the stretchers, small wooden angled chips, which are used to make the stretched canvas more snug in the corners. These are free, and are usually found near the stretcher bars, in a box. You need 8 of them; just grab a small handful when you buy your stretcher bars.

The anatomical study deepens the knowledge of G-type conducting cells: 1 It proves the theory of two depositional process for secondary wall (Bierhorst, 1960): the discontinuous cellulose layer is laid down before the continuous lignified layer; the former layer is prone to be broken down, while the latter is highly decay-resistant; 2 It suggests that the cellulose primary and secondary walls of tracheids are not perforated. Instead of longitudinal pits (Li, 1992), the lignified tracheid secondary wall of Hsüa possesses irregular simple perforations; 3 In Hsüa reflexa and Huia gracilis, the perforation casts may represent the thickness of lignified secondary wall; 4 The wall structure of G-type tracheid is diversified. At the genus level, the secondary wall structure differs in the distribution, internal shape and structure of the perforations; 5 Perforations of some G-type tracheids combine the characters of S-type tracheids in their distribution, density and diameter.

解剖学的研究加深了对G-型输水管胞的认识 1）验证了管胞次生壁分两个阶段形成的理论（Bierhorst，1960），即先后形成不连续的纤维质层和连续的木质化层，前者易被分解，后者抗侵蚀性强；2）证明管胞纤维质的初生壁和次生壁不具穿孔，Hsüa管胞的木质化次生壁具有不规则的简单穿孔，而不是纵列的纹孔（Li，1992）；3）Hsüa reflexa和Huia gracilis的穿孔铸体可代表木质化次生壁的厚度；4）G-型管胞壁层结构具多样性，植物属一级的分异主要表现在次生壁穿孔的分布、孔腔形状和结构的不同；5）某些G-型管胞的穿孔在其分布、密度和孔径方面可兼有S-型管胞的特征。

The computational formula of dew point temperature was presented according to the physical feature of water vapor such as Michell's saturated water vapour pressure formula. Surface temperature inside wall body was also calculated. Then the comparison between them verified whether wall body has dew. At the same time, the temperatures of every material layer inside wall body were calculated. The partial pressures of saturated water vapour and actual partial pressures of water vapour for every material layer inside wall body were obtained. The two were compared so as to verify whether condensation appears inside wall body.

根据Michell饱和水气压计算公式等水蒸气的物理特性，给出了露点温度计算公式，再计算出墙体内表面温度，将二者进行比较，从而验证墙体是否结露；同时计算出墙体内部各材料层温度，求出墙体内部各材料层的饱和水蒸气分压力及各材料层实际水蒸气分压力，将两者比较，从而验证墙体内部是否出现冷凝。

Through block wall experimental study we can find out that cracks would appear late and the load of crack-resisting and limit-resisting are increased obviously by the constructional measures in the wall. It is very effective method that the splayed cracks are controlled by sill ring beam, the horizontal bending cracks are controlled by structural column on the side of the wall and the horizontal cracks on the top of the wall are controlled by the whole ring beam. It is the most effective method that wall cracks are controlled by structural column, crout column and sill ring beam.

通过试验主要得到在墙体中采取构造措施后，墙体裂缝推迟出现，开裂荷载和极限荷载都有很大程度的提高，同时发现窗台圈梁在控制窗角的八字缝、墙体两侧构造柱对于防止水平弯曲缝以及全截面的圈梁在防止墙体和圈梁交界处的裂缝的出现能起到很好的效果，通过试验确定在砌块墙体中采取&构造柱+芯柱+窗台圈梁&的构造措施来控制裂缝是最为经济合理有效的。

And the long axis of simple pit Varied along with CMfs orientation of each secondary wall.This paper proposed a structure model of Phyllostachys pubescens cell wall,based on the results of CMfs deposition and thickness of each secondary wall.Secondly, it was a multilamellate structure of parenchyma cell wall,but its thin and thick lamellate was not evident.CMfs orientation on primary wall of parenchyma cell was perpendicular to cell axis.

纤维的细胞壁为典型的薄厚层相间的同心圆多层结构，初生壁CMfs排列方向与细胞轴向垂直90°次生壁中厚层的CMfs均以接近平行的小角度(0～5°沉积；薄层一般以大角度沉积，且薄层的CMfs角度由壁外侧向细胞腔里逐渐增加，直到完全垂直。

Due to their high strength and overall performance, the panels can be used as division and partion wall even the wall is very high and wide. Only steel structure should be used for fixing which is unstalled inside the wall and it is unnecessary to add wall posts. The anti-blast performance is 1.5 higher than that of brick wall.

由于强度高，整体性能好，因此可用作层高高、跨度大的墙体间隔，只要简单地采用钢结构锚固，型钢埋设于墙体内，大跨度，层高高的墙体就无需增加墙面的柱体，其抗冲击性能是一般砌体的1.5倍。

Displacement of wall reduced with increasing of supporting severity, until it reaches the critical valuation.(4) Severity of enclosure wall. With wall thickness increasing, the flexural torque of wall increase, but the body deform are reduced. However, we should consider the economic factor when we use the method which use increase the wall severity to reduce its displacement.

支撑刚度的影响，支撑刚度增大时，墙顶位移减小，直到增加到临界值后影响变小（4）围护墙刚度的影响，围护墙厚度增加，墙身变形就相应减小，围护墙弯矩也进一步增加，但是利用增大围护墙刚度来减小变形时应结合经济因素一同考虑。
