The main works of this paper are as follows.First, according to the three-step method, 1-D unsteady flow model in river network is introduced. A new topological structure is presented to describe and store the topology information and data in river network ,which realises the connection between GIS and the numerical program of hydraulic calculating and turns the program into a universal one .A new formula of internal boundary conditions with double-recursion algorithm is deduced, and the relationship of recursive coefficient between imaginary channel length and non-imaginary channel length is presented ,which makes sure that the model can comprise the numerical simulation of the internal boundaries such as side pipe outflow ,barrage, slice gate and drainage pump station.

主要工作如下：(1)根据三级解法建立了一维河网非恒定流模型，并提出了一种新的数据结构来描述和储存河网拓扑信息，方便了GIS平台和数值计算程序的衔接，实现了三级解法程序的通用性；从河段方程组出发，根据虚设河段法推导出了内边界条件的双追赶法公式，指明了虚设河段的追赶系数和非虚设河段追赶系数的关系，从而使模型可以模拟集中旁侧入流、堰、闸、水泵等内边界对行洪过程的影响。

Recent progress in radio prototype has extended the horizons of radio technology by liberating chronics dependence on hard-wired characteristics including frequency band, channel bandwidth, and channel coding. These efforts have led us to the feasibility of dynamically programmable receivers system of software radio.

软件无线电系统的硬件结构与功能相对独立，这样就可以基于相对通用的硬件平台，通过软件实现不同的通信功能，并可对工作频率、系统频带、调制方式等进行编程控制，系统的灵活性大大增加。

Between 4-9L exposures, C2H4 has a desorption channel at 155-180K. C2H4 desorption at 130K maybe results from BrCH2CH2Br absorbs in Br atom toward surfaces, after C-Br bond scission, because C2H4 has no opportunity to touch surfaces so it desorbs at low temperature. C2H4 desorption at 210K is likely to be desorption limited that, BrCH2CH2Br docomposes to C2H4, only to desorb at higher temperature. This C2H4 desorption channel maybe comes from defect site desorption.

曝露量在4-9L之间，C2H4在155至180K的范围内也有脱附的管道。130K的C2H4脱附可能是因为BrCH2CH2Br分子以Br原子朝向表面的方式吸附，在断了C-Br键后，C2H4分子没有机会接触到表面在低温就脱附了。210K的C2H4可能是脱附所决定的，亦即BrCH2CH2Br分解后在表面形成C2H4，随后温度升高至较高温才从表面脱附，此C2H4管道也许是来自缺陷位置上的脱附。

Salty and sour directly transduction by apical channels that are non-gated channel or chemically-gated channel. Bitter compounds in saliva activate particular T2R/TRB isoforms which activate gustducin heterotimers, activated α-gustducin stimulates PDE to hydrolyze cAMP, the decreased cAMP may disinhibit cyclic nucleotide-inhibited channels to elevate intracellular Ca2+.

咸和酸直接通过顶部非门控或化学门控离子通道转导唾液中的苦味化合物激活T2R/TRB同型体，激活导致味导素异聚体的激活，被激活的α-味导素又激活PDE，PDE水解cAMP，cAMP水平的降低使环核苷酸抑制的阳离子通道去抑制，从而使细胞内Ca2+升高。

Finally we combine turbo code with OFDM technology ,then make some emulations under several kinds of channel fading types in the mobile communication ,it has offered new choice for turbo code applying in fading channel.

所以最后我们将Turbo码与OFDM技术相结合，针对移动通信信道的各种不同的衰落类型进行仿真分析，为Turbo码在衰落信道中的应用提供了新的选择。

Determination of reverse link performance may be done in variety of ways, including use of a filter percentage of ACK erasures, measured error rates on the reverse link control channel, reverse link data channel error rates, and other methods.

反向链路性能的确定可以通过各种方式进行，包括利用过滤后的ACK删除百分比，反向链路控制信道上的被测差错率，反向链路数据信道差错率，以及其它方法。

So, channel fadings can be exploited. But the multi-user diversity gains are limited in two ways. First, there may be a line-of-sight path and little scattering in the environment, and hence the dynamic range of channel fluctuations is too small.

因此，信道衰落是可以利用的，但这种多用户分集受到两方面因素的制约：一是在LOS和非散射信道环境，信道变化范围太小；二是如果信道衰落变化太慢，则不能满足对时延要求严格的应用。

Information Theory has shown that if the channel fadings of multiple users are independent and scheduling the transmissions to the users when their instantaneous channel quality is near the peak, the total throughput of system can be maximized and it is direct ratio to the number of users.

信息论分析结果表明，如果多用户的信道衰落相互独立，任一时隙只服务于信道最好的用户，则系统的总吞吐量可以最大化，而且与用户数成正比，对于不同的用户数，衰落信道的容量几乎都能高于AWGN信道。
