板层

Through this veil , the aluminum plates inside with various colors deliver an aesthetic feeling of haziness .

外面一层是由穿孔铝板组成的网罩，透过这层"面纱"，里面的不同颜色铝板渗露出来，有一种朦胧的美感。

Compared with results of two methods, GA method is much better than the 'isotropy' method .

本文通过对层合板热膨胀系数的研究和设计，指出了过去常用的零膨胀系数的工程设计方法在精度上的不足，应用遗传算法进行优化设计的层合板更加接近真正意义上的零膨胀。

Furthermore, GA method also overcomes the shortcoming of the'isotropy'method that can be only used for laminate composed with one kind of material.

另外应用遗传算法对由多种材料组成的层合板进行了零膨胀系数的设计，弥补了工程设计方法只能对由单一材料构成的层合板进行设计的不足。

Crack is one of the most common damages in composite laminated plates,and it is the chief factor of causing failures.

裂纹是复合材料层合板的主要损伤类型之一，也是造成复合材料层合板失效的主要原因。

Carbon/epoxy is one of lamination composite which is made of carbon

碳环氧是碳布与环氧树脂构成的一种层合材料，可以将该材料近似看成是由单向碳纤维增强板叠合而成的层合板。

For more than 10 years,through continuous exploring and improving of bamboo and wood pancl,we developed a series of excellent products.including bamboo veneer sheet for all kinds of carriage and container.high-strength double-tunica bamboo templates,and timberwork plywood,etc.

十多年来，企业通过对竹木材胶合板不断探索、改良，开发出一系列性能优异的产品，其中有各种车厢、集装箱用竹材积层板、竹编胶合板、高强度双履膜竹质模板、木材层压板等。

In addition, the influence of the pressure applying moment and precure conditions on the quality of S2 glass fiber/cyanate resin composite laminates was analyzed for hot press process.

在此基础上，针对S2玻璃纤维/氰酸酯复合材料层板，采用热压机工艺考察了加压时机和预固化对层板成型质量的影响。

In order to investigate the basic heat transfer characteristics of the platelet regeneratively cooled thrust chamber, the second chapter focussed on the developed flow and heat transfer in the long straight regenerative cooling channels with rectangular sections.

为了解层板再生冷却推力室在传热上的基本特征，第二章重点研究流动和热充分发展的矩形截面长、直再生冷却通道内的传热问题，建立了层板再生冷却推力室二维流固耦合传热过程的数理模型，采用通用形式控制方程描述冷却剂紊流传热和通道材料内导热的共轭传热问题，从而避免了流-固区域之间的反复迭代，大大缩短了计算时间。

Methods Fifty healthy SD rats were fed for twentytwo months in order to build the model of aging rats, the histology of femoral bone, tibial bone and lumbal vertebra was used to observe, then we evaluated the indexes which reflect the degeneration of intervertebral disc including the quantity of collagen type Ⅱ,Ⅹ of intervertebral disc by the immunohistochemistry methods, the relative area of vascular bud, the thickness of calcified layer and uncalcified layer on cartilage endplate and the indexes which reflect the osteoporosis including the thickness ratio of cortical bone, the relative area of bone trabecula, the bone density, the max stress and straining of bone.

50只健康纯种SD大鼠，喂养22个月，建立老龄大鼠模型，进行股骨、胫骨、腰椎等组织学观察，并评价椎间盘退变的相关指标(椎间盘软骨Ⅱ型和Ⅹ型胶原表达、软骨终板血管芽相对面积、软骨终板钙化层/非钙化层厚度)与骨质疏松的相关指标(骨皮质厚度指数、骨小梁相对面积、骨密度、骨最大应力和应变)的相关性。

For comparison, the unnotched laminate coupons are also tested. Although both notched and unnotched coupons fail in the mode of buckling, there are still some apparent differences in the features of the failure process.

作为比较，对无缺口层压板也进行了压缩试验，尽管2种层压板试样随载荷增加到一定值时都会发生屈曲，但它们的破坏过程仍有着显著的差别。
