A three-dimensional simulation method based on Matlab was designed. Moreover its better simulation was verified by a contrast diagram from different fiber finesses and a figure after three dimensional mapping. Finally, the main applications and their development directions for the two methods were prospected on a simulation based on lines and a three-dimensional map.

Four classes of partition models , empirical models , functional equilibrium models , optimal control models , and source-sink models were reviewed in this paper. The empirical models were widely used with minimal mechanistic assumptions. The function equilibrium models were successful in the simulation of the rootPcanopy ratio at the periods of the vegetative growth , but were poor to simulate portioning among other organs. The optimal control models were suitable for the modeling under the equilibrium state. The source2sink models were the most powerful and mechanistically based models capable of simulating dynamic photoassimilates partitioning between any organs of the plants.

对于同化物分配模型按照经验模型，目的性模型，源汇关系模型进行了总结归纳，分析指出：经验性模型应用最多但机理性差；功能平衡模型在模拟营养生长阶段同化物在条与根之间的分配很成功，但应用于其它器官之间很困难；最优化模型适于模拟平衡态下同化物的分配；源汇关系模型机理性最强，可模拟任何器官间的同化物分配，应用范围最广泛。

The speech semaphore analogs wave form and delivers a speech through IP method and ignore to is a real time appliance a traffic still a non- real time applied traffic, the pass looks shore wants to steer a simulation data convert to the speech semaphore first, is also vs simulation the speech semaphore steer 8 or 6 quantizes, then send go into to buffer store ward amid, the dimension of dampener can be sur the request select of the delay and the encode.

语音信号是模拟波形，通过IP方式来传输语音，不管是实时应用业务还是非实时应用业务，道貌岸首先要对语音信号进行模拟数据转换，也就是对模拟语音信号进行8位或6位的量化，然后送入到缓冲存储区中，缓冲器的大小可以根据延迟和编码的要求选择。

Whenyou find out the world simulates that world is again just a simulation, what will you do?

当你发现模拟出这个模拟世界的世界也只是一个模拟出来的世界，你会怎样？

The numerical model is capable of handling both subcritical, supercritical and transcritical flow, free surface and surcharged flow.

为了验证所建立的数学模型的可行性，本文计算了多个具有解析解或试验结果的算例，并对利用不同计算参数获得的计算结果进行了分析比较，结果表明：明满流模拟中，采用较小的狭缝宽度和较小的空间步长能够提高解的精度；跨临界流模拟中，采用删减对流项法模拟急流需要补充自由出流水位流量关系作为下游边界条件等。

A simulation's complexity has to be within the ballpark of the complexity of the modeled; otherwise the model can't keep up with the zig and zags of the thing modeled.

模拟的复杂程度必须在它所模拟的东西的复杂性的活动领域之中，否则，模型就跟不上它所模拟的东西的曲折路线。

A simulation's complexity has to be within the ballpark of the complexity of the modeled; otherwise the model can't keep up with the zig and zags of the thing modeled.

对于一个模拟来说，它的复杂程度，必须在它所模拟的那个东西所具有的复杂性的活动领域之中。否则，模型就跟不上它所模拟的东西的曲折路线。

A simulation's complexity has to be within the ballpark of the complexity of the modeled; otherwise the model can't keep up with the zig and zags of the thing modeled.

对于一个模拟来说，它的复杂程度，必须停留在被它所模拟的那个东西所具有的复杂性的活动领域之中。否则，模型就跟不上它所模拟的事物的曲折路线。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
