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。
