In this paper, the bump patterns for flip-chip packages are discussed first, then an experiment is setup to study the dispensing phenomena for different bump patterns, and the CAE software is used to analyze and identify with experiment mutually. From these thorough comparisons and analytical analysis, the existence of channel could slow down the flow, the high density of bump could speed up the flow, and it could avoid the air trap by modified the bump and channel's arrangement on flip-chip package. Then flows in rectangular microchannels driven by capillary force and gravity are discussed; furthermore, the theoretical model of flow in microchannel driven by capillary force and gravity is formulated from the Navier-Stokes equations.

本文首先针对覆晶底部充填进行相关理论推导、实验与模拟，探讨不同凸块配置模型所造成的波前不平滑现象对底部充填流动的影响；即依据相关参数建立模型进行底部充填实验，同时以CAE(Computer-Aided Engineering)模流分析软体进行模拟，在完成理论探讨、实验与模拟分析之后，交叉比较理论、实验与模拟分析结果，归纳出影响底胶充填流动之因素，由结果显示在凸块密集度较高的区域，凸块可以帮助流动，但是在凸块区后方的沟槽区域则因为凸块区所提供之流量不足，所以会造成波前落后的现象，另外藉由修改凸块与沟槽配置的关系，可以有效的控制波前形状的变化情形，避免产生包风现象。

The mechanism of PPS accelerating IEC-6 cells migration was also researched with gene-chip technique. The Altas Clontech Rat cDNA Chip which consisted of 1176 spots representing different functional categories such as heat shock/stress, cell cycle, transcription factors, hormones, metabolism, etc was used. Result showed in cell migration model of IEC-6 cell line, compared with control group, expression of 38 genes in total 1176 genes varied in cells treated by PPS, including 21 genes up-regulated and 17 genes down-regulated. Date analyze showed the mechanism of PPS accelerating IEC-6 cells migration mainly related with promoting the numbers and activity of cellular ion channel, especially 〓 channel.

从以上实验结果中我们可以得出以下结论：四君子汤总多糖具有促进IEC-6细胞增殖、迁移、粘附的作用；四君子汤总多糖无论是对IEC-6细胞增殖、或者迁移的作用均优于各单味药多糖，可能是各种单味药多糖综合作用的结果；多糖可能是四君子汤"益气健脾"药效的主要成分；小肠上皮细胞可能是四君子汤总多糖的作用靶点之一，提示临床采用四君子汤及"益气健脾"法治疗"脾虚证"的疗效机制可能与增强机体的整体免疫和肠道粘膜免疫功能有关。

First it produces the pulse signal by the multivibratorwhich is consisted of 555 timer and send in the detecting coil to form the alternating magnetic field, then it asopts UGN3503 linear half-effect as prode to the magnetic field change into the voltage signal change,after enlargement electric circuit and peak value examination electric circuit,the signal be treated to send into ADC0809 modulus converter change moduluses, then the digital signal after the modulus converter is changed is sent into AT89C51one-chip computers afterwards, after the digital filter, AT89C51one-chip computers afterwards compares the data to the reference voltage and judges whether to have detected the metal and alarm.

这个系统是以AT89C51单片机为核心，首先由555定时器构成多谐振荡器产生脉冲信号送入探测线圈以形成交变磁场，然后经过线性霍尔器件UGN3503将磁场变化转换为电压信号的变化，经过放大电路和峰值检测电路，经数模转换之后输入到单片机中，由单片机对数据进行软件滤波之后，与基准值比较之后，判断是否存在金属和报警显示。

Of course, it is Galaxy series product got paying close attention to not just, this year August, the company announced to release 8 kernels, every kernel the Niagara2 chip of 8 lines Cheng, the network that the function of the buy inside Niagara 2 includes per sec. 10Mbps, add communication of close, PCI Express and 4 memory controller to wait amain, it may be said is an example of odd chip system.

当然，不仅仅是Galaxy系列产品得到了关注，今年8月份，公司宣布发布了8内核，每个内核8线程的Niagara2 芯片，Niagara 2内置的功能包括每秒钟10Mbps的网络、全速加密、PCI Express通讯以及4个内存控制器等，可谓是单芯片系统的一个典范。

With the latest chip:The RK2706 of Rockchip, V8 has a strong and powerful processor , containing Microsoft PlayFX, and you can enjoy arioso music of high quality,which is apparently better than those with the chip of Chinachip.

由于采用了瑞芯微RK27系列芯片，处理能力相对较强，内含微软音效设置，为本机增色不少。经过测试，可以肯定的说，比使用华芯飞的机子音质要好，这多亏了微软的重低音功能。如果你并不要求非常专业和苛求的音质，那么可以毫不犹豫的说，V8的效果是可以满足你的大众耳朵的。
