Based on the spectral characteristics of underlying-surface and the principle of satellite observation, a simple and effective method for waterbody identification using MODIS data is put forward, which is the ratio band of channel 2 by channel 1. The effect result of waterbody identification in the ratio image can be obtained. Using this method, water can be identified not only in cloud-free areas, but also under semitransparent cloud.

Simple minded tells us to arrive from the development at the beginning of 2008 now, a year of time of half, the locomotive condition of whole company, to us character, itself invests a website, more than it is net of a wisdom room, still still have an economy channel other, itself still has other channel to be in gain, we are to be on the foundation that lasting effect expands, so whole gain is this disappear those goes up.

老实讲我们从2008年初发展到现在，一年半的时间，整个公司的运转情况，对我们而言，本身投资一个网站，不止是一个智房网，还有一个经济频道还有别的，本身还有别的渠道在盈利，我们是在长效壮大的基础上，所以整个盈利是此消彼涨。

The numerical simulation of two-phase flow field in the reactor is carried out in this paper. The distribution of shearing strength in the channel is systematically obtained:① The shearrates of wall, vortexcore, vorticity and non-vorticity regions are descending sort.② With Re number increasing, the average of shearing strength becomes linearly increasing tendency in the back step expand channel.

通过对涡旋波膜生物反应器中的两相流流场进行数值模拟，系统地研究了反应器内的剪应力的分布规律：①壁面、涡心、旋涡生成处及非旋涡生成区的剪切应变依次降低；②随着Re数的增大，扩张区内剪应力的平均值呈线性增加趋势。

For example, an inexpensive 2-channel sound card may be good enough for someone initially, but down the road they may decide that something like the 7.1 channel Sound Blaster Audigy 2 offers the sound quality they really want.

举例来说，一个便宜的双声道的声卡对于初用者来说就足够好了，但是接下来他们可能决定他们所需要的是能给他们提供真正想要的声音品质的7.1声道声霸卡2。

In order to overcome the disadvantage of volume effect and improve prospecting precision of MT, the paper puts forward a multi-channel telemetry method of stratum resistivity for linearity processing exploring depth and electromagnetic frequency in the local area, which creates a crresponding relationship between stratum resistivity and sounding line, and a multi-channel observation system is designed accordingly to explore the resistivity of underground ledge.

为克服大地电磁勘探中"体积效应"的缺点，提高探测精度，提出多道遥测地层电阻率法，该方法是在一个局部区域内，将勘探深度和电磁波周期进行线性化处理，使得地层电阻率和测深曲线建立对应关系，并据此设计了一个多道探测地下矿层电阻率的观测系统。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.
