什么是bar code?

去过酒吧(bar)吗?去酒吧还需要什么口令(code)吗?不太可能吧,酒吧又不是什么军事基地。那么,bar code又是什么意思呢?bar除了作“酒吧”讲外,它还有“细长条的形状”的意思,code是“密码”,因此二者组合起来就是“条码”。

Analysis of 3D curve expansion of conical cam with oscillating tapered roller follower

This paper focuses on the analysis of running conditions and machining processes of conical cam with oscillating follower. We point out the common errors existing in the design and machining of the widely used plane expansion method of conical cam trough-out line. We show that the motion can be divided into two parts, i.e. the oscillating motion of oscillating bar and the rotary motion of oscillating bar relative to the conical cam. By increasing the rotary motion of oscillating bar, the motion path of tapered roller on oscillating bar (i.e. contour surface of conical cam) can be expanded on the cylinder. Based on these analyses, we present a creative and effective designing and machining method for 3D curve expansion of conical cam with oscillating follower.

Numerical Analysis of Quality Inspection of Anchorage System

Sonoprobe method has been applied in non-destructive inspection of anchorage project.The fundament is that dynamic transient excitation causes the elastic vibration of an anchor bar,and flaws can be estimated or deduced by determining transient response of the anchor bar.FEA numeric solution of hyperbolic equation indicates that deductions must comply with acoustic parameters such as velocity of sound,vibration range,wave shape etc when inspecting interior flaws in the grout of an anchor bar,Based on wavelet packet analysis,the energy eigenvector is a flaw vector,which could be regarded as the basis in the nondestructive inspection of anchors,As a non-linear dynamical system,artifical neural networks dealing with quality insection of gray system have been proved efficient.

喷油器结构对电控柴油机性能及排放影响研究

在电控柴油机上研究了喷油器突出高度、孔径、开启压力等喷油器结构参数对电控柴油机性能及排放的影响,并通过对比实验确定最优参数。试验发现,合理选择喷油器突出高度能够在油耗、NOx和烟度之间获得较好均衡;较小喷孔直径的喷油器对缸内气体流动强度的依赖较小,有利于柴油机低速性能改善,启喷压力从255bar提高到300bar对经济性影响不大,碳烟排放有所改善,但NOx排放变差。     

气相甲醇合成二甲醚生产过程优化研究(Ⅰ)--二甲醚分离塔的计算机优化

采用AspenP1us模拟软件对二甲醚（DME）生产流程进行了模拟,并对DME分离塔的操作条件进行了优化。当塔顶压力为8．3bar,塔底压力为8．5bar时,计算得到最佳理论板数为20,最佳回流比为0．521,最佳进料塔板为8。在最佳条件下操作,DME回收率为99．8％,DME纯度为99．95％以上,达到了优化目标。
