Two one-ply weaves should be compounded to a two-ply weave at first, then one two-ply weave and an one-ply weave should be compounded to a three-ply weave, at last, the two three-ply weaves can be compounded to a six-ply weave.

设计时先由单层组织复合为双层组织，复合时在表经和里纬的相交处填上分层符号，再分别由一个双层组织加一个单层组织复合为一个三层组织，最后由两个三层组织复合为六层组织。

The nuclei were clear and the cell was well-stacked. Double layer structure could be seen in part of areas, displayed as monostratal keratinocytes linked with string-like cells. Most of keratinocytes differentiated into double layers, and cells linked with others with cable-like structure. The nuclei still could be seen.

部分区域细胞出现双层结构，表现为单层的角质形成细胞上面铺有连接成条索状的细胞。3周的角质形成细胞大部分为双层结构，异层及同层细胞之间彼此衔接，呈索形结构，细胞核仍然清晰可见，细胞不如2周时饱满。4周的角质形成细胞部分区域为三层结构，且细胞较前变得萎缩，表现为细胞浆减少，细胞核变小。

A lot of organelles such as mitochondria, rough endoplasmic reticula and Golgi bodies were observed in fiber cell. Then, double karyotheca disappeared, and the organelles disintegrated. Multivesicular bodies appeared in fiber cytoplasm. With the further development of fiber, fiber wall underwent continual thickening with aging, and polylaminate structure gradually appeared. While the agglutinated nucleus, transfer vesicles, plasma membrane and plasmodesmata still presented.

研究发现，次生壁形成早期，细胞核具有双层核膜，染色质凝聚，可见大量的线粒体、粗面内质网和高尔基体等细胞器存在于纤维细胞中；随后，双层核膜消失，细胞器将逐渐解体，多泡体开始出现在纤维细胞的细胞质；随着年龄的增加，纤维细胞壁逐渐增厚，并出现多层结构现象，而运输小泡、细胞膜、胞间连丝和凝聚的染色质将持续存在。

The main experimental methods and results of determining water potential distribution and variation for unsaturated water vadose passing through two-layer porous media made of loess and quartz sand are introduced in this paper in order to analyze and explain further detouring flow phenomenon observed in former work.

本文主要介绍非饱和水通过以黄土和石英砂组成的双层孔隙介质渗流的水势分布和变化的实验方法和主要实验结果，用以进一步分析解释以前工作中观察到的非饱和水在双层孔隙介质中的绕流现象。

In this paper, the research has been given on the double weldable ceramic cutting tool by means of the acoustic microscope .

利用声学显微镜对双层可焊接陶瓷刀具材料进行研究，对双层材料界面及影响材料品质一致性的因素进行了分析，发现了两种材料在界面结合处分布不均匀及成块状分布等现象，并提出了改进材料设计的思路。

The device consisted of an array of 6×6 cell culture chambers, a drug gradient generator and fluidic control valves. Micro-dam structures of the chambers were able to trap cells while loading and drug gradient network generated drug gradient of 6 different concentrations. Also we applied hydraulic valves to control the microfluid and simulate the microenvironment of cells.

本研究介绍了一种利用SU-8负性光刻胶模具和PDMS制作双层结构的微流控细胞阵列芯片的方法，该芯片通过C型的坝结构将进样细胞拦截在芯片的细胞培养的固定区域，键合双层PDMS构成阀控制层，阀网络的开关作用成功实现了芯片通道内微流体的操控，同时芯片设计了药物浓度梯度网络，产生6个不同浓度的药物刺激细胞。
