Capillary phenomena was studied and discussed by the scholars about 200 years ago, but the progress was slow due to the limited equipments and manufacture precision of the microchannel.In recent years, because of the rapid development of MEMS and micromachining, many applications of the capillary flow is widely developing in some modern processes, such as underfilling of flip chip, flow in microfluidic chip or biochip, and a variety of other fields.

摘要 毛细现象大约在200年前便断断续续被欧美学者所研究讨论，但由於当时微细加工受到仪器设备和制造精度的限制，因此发展极为缓慢；近年来由於微机电系统与微细加工之精进，许多具有微流道的应用设备，陆续被制作问世，加上光学显微镜与影像撷取设备的普遍，对於研究此课题的推展极有助益；且随著微生医、覆晶底胶充填与微流体系统等领域之受到重视，毛细现象导致的充填问题、驱动原理及液体流动的控制，都变得相当的重要；本研究基於如此的动机与目的，进行微流道内液体之毛细流动现象及时间的探讨。

System modeling involves with both functional modeling and timing modeling, which relate with computation model (eg, Data-flow-oriented vs. Control-flow-oriented, Uni-processing vs. Multi-processing), time model (eg, Continuous vs. Discreet, Time vs. Untimed, Cycle-based vs. Non-cycle-based, State-based vs. Event-driven, Branching-time vs. Linear-time, Single-rate vs. Multi-rate) and communication model (eg Shared Variable vs. Messaging Passing).

涉及系统建模与功能建模和时间建模，涉及的计算模型（例如，数据流导向与控制流为导向，统一处理与多处理），时间模型（例如，连续主场迎战Discreet公司，时间与Untimed ，周期为基础的与非周期为基础，以国家为基础与事件驱动，分枝时间与线性时间，单率与多速率）和通信模型。

Firstly, MRED compares the send rate upbound of the TCP throughput modal with the tartet rate of the UDP flows, and then the relation curves can be gained about throughput and packets drop probability. Secondly, by controlling the packets drop probability on the network nodes, the throughput of the UDP flows can be adjusted and transforms the response manners to the network congestion.

MRED算法根据TCP吞吐量模型发送速率上界与UDP业务流的目标速率比较，得到吞吐量与数据包丢失率关系曲线，通过在网络节点控制数据包丢失率来调节UDP业务流的吞吐量，可以改变其对于网络拥塞的响应方式。

The inadequacy that exists in this domain is, the method that the three-dimensional parameter of clipper-built flow path changes the aspect that build a model exists to use a sex indeed mostly not strong, perhaps cannot be opposite model antrum curved surface undertakes parameter changes three-dimensional parameter of pilot defect; to change flow path model to not was aimed at its function feature to undertake differentiating, go against optimize a design further.

该领域中存在的不足是，流线型流道的三维参数化建模方面的方法大多存在着实用性不强，或者无法对型腔曲面进行参数化控制的缺点；三维参数化流道模型没有针对其功能特征进行划分，不利于进一步的优化设计。
