Results The endothelial cell and fibroblast of valves and vessel walls in experimental group were completely decellularized, no cell fragments were retained within the matrix scaffold; collagen fiber and elastin fiber had been preserved with intact structure and wavily arrayed; deoxyribonucleic acid content of valves and vessel walls in experimental group were decreased by 97.58%, 97.25% compared with that of control group.

结果 实验组瓣膜及血管壁中内皮细胞、成纤维细胞去除完全，无细胞核碎片；瓣膜及血管壁胶原纤维和弹力纤维呈波浪状排列、整齐，结构完整；瓣膜、血管壁的基因组脱氧核糖核酸含量分别较对照组下降97.58％和97.25％。

New process fabrication designs, multiport divert valves, and modular valve assemblies that are offered by the major manufacturers of weir type diaphragm valves have brought innovation and value to customers with critical applications

新工艺制造的设计，多端口分流阀，阀门和模块化是所提供的集会的主要堰式膜片的阀门制造商带来了创新和关键应用，实现客户价值

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。

The results of this study indicate that changing the angle of the intake port has a profound effect on the flow field during the intake stroke of the engine cycle. For the case with the intake-exhaust valves canted at zero degree (the so-called vertical valves), the tumble ratio, swirl ratio, turbulent intensity, and turbulent kinetic energy in the direction perpendicular to the bisecting plane of the cylinder are at their highest levels than those obtained for the other cases. This effect is most pronounced after the compression stroke of the cycle. As a result of this study, it is observed that the behavior of the overall flow field from the intake to the completion of compression stroke has a major impact on the effectiveness of the mixing of fuel-air prior to the ignition of the engine cycle.

结果显示，改变进排气阀的倾斜角度对进气期间的流场变化有很明显的影响，其中以垂直阀(进排气阀倾斜0度)所得的 Y轴向(Y方向系垂直於将汽缸对分为二平面的方向)滚流强度、涡漩比、紊流强度、紊流动能等流场强度为最强；若以流体经活塞压缩后的流场特性进行探讨，所得结果显示压缩冲程对汽缸内流场的效应是不容忽视的；因此由进气到压缩过程结束的整体流场现象，才是影响引擎点火前的油气混合程度与燃烧品质的关键。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
