Many phytoplankton and autotroph absorb the DIN of the bottom water that decrease content of DIN in bottom water and change the fluxes of the DIN. And the activity of those phytoplankton and autotroph can even change the direction of DINS fluxes.

在有光的条件下，浮游藻类和一些光自养生物对沉积物水界面溶解态的营养盐的直接吸收，从而减少了上覆水中可与沉积物可交换的营养盐的含量；浮游植物的活动甚至有可能改变无机氮在沉积物水界面的扩散方向。

When formed, the internal tides travel away from its generation area. Wherever it reaches, it makes the sea water there mixing heavily and the objects exchange up and down, which influences the distribution of ocean biocoenosis and the action and the safety of submarine and other objects in the ocean. Therefore, it's very important to study internal tides both in application and in theory.

内潮向浅海和深海传播，所到之处，海水会发生强烈的垂直混合，使上下层的物质发生交换，从而影响到海洋中生物群种的分布以及水中工程设施、潜艇等的功能及安全，所以，对内潮的研究有着重要的理论和实际意义。

Firstly, we get the necessary and sufficient conditions for Toeplitz operators that commutes with another such operator whose symbol is a monomial, meanwhile, we completely characterize when the mellin transform of the bounded function on the interval 0,1 is a rational function.

首先得到了以有界函数为符号的Toeplitz算子和以单项式函数为符号的Toeplitz算子可交换的充要条件，同时给出了0，1区间上的有界函数的Mellin变换为有理函数的充要条件。

We found a lot of "good" things: Pai Qishan and the principle of exchange of hot and cold air base station to replace the engine room inside the air-conditioning, to achieve the effect of reducing power consumption, it is really a good idea; education in remote video platforms around the Zu Buchu school teachers teaching skills can be a PK, saving a lot of traffic and the cost of the emissions, conditional schools should have no reason to reject it; use of SMS, MMS study the "scientific concept of development", certainly than Daidai De-in the office listening to read documents more effective leadership, Why not

我们发现了很多"好"东西：用排气扇和冷热空气交换的原理取代基站机房里面的空调，从而达到降低电力消耗的效果，这真是一个不错的主意；在远程视频教育平台上各地的老师足不出校可以进行教学技能大PK，节省了大量的交通成本以及带来的尾气排放，有条件的学校应该没有理由拒绝它；利用短信、彩信学习"科学发展观"，肯定比聚在办公室里呆呆地听领导读文件更有效果，何乐而不为？

In many xerophytes and in some conifers of cooler climates, where soil water may be difficult to obtain in winter, the guard cells-and hence the stoma-are sunk in pits in the epidermis, often protected by hairs form passing air currents. TRANSPIRATION rates are thus greatly reduced, while allowing gaseous exchange for photosynthesis.

一些旱生植物和寒冷气候带的针叶树在冬季很难从土壤中得到水分，因此它们的保卫细胞和气孔在表皮上下陷成为气孔窝，常被表皮毛保护，可以在满足光合作用所需的气体交换的同时防止通过的气流带走大量水分，大大降低了植物呼吸率。

May be impossible. Pan of the reason why these swaps can be done is the willingness of

大自然交换的代价的另一个问题是在一个大的尺度上使用或许是不可能的。

Then, on the basis of modeling the manufacturing cell with the O-O method, the information model of the manufacturing cell is described with XML language. It provides a method of information exchange to the optimization and configuration of manufacturing cell together with the development of application system.

其次，在制造单元信息模型的基础上，使用XML语言对制造单元信息模型进行了描述，为制造单元的优选配置以及应用系统的开发提供了信息交换的方法。

We analyzed and discussed the characteristics of cycle of carbon and water,and after having obtained important physiological parameters based on field experiment,a process-based, multilayer two-leaf model which calculates energy and material cycle separately for sunlit and shaded leaves was developed,then characteristic of CO_2 fluxes above the canopy was simulated.The main results are as follows:1.Characteristics of carbon and water cycle in the relationship of leaf photosynthesis -stomatal conductance-transpiration.

本研究以冬小麦为研究对象，利用LI-6400R光合—蒸腾测量系统、LI-6400-09土壤呼吸室和禹城生态试验站涡度相关系统等高精度仪器设备，对2007年和2008年小麦拔节至乳熟期间涉及碳、水循环过程的叶片光合—蒸腾作用、土壤呼吸作用及相关农田气象要素和植被特征进行了野外试验测定和分析，在试验观测基础上提取了重要生理参数，建立了基于过程的农田与大气间物质输送和能量交换的多层—双叶模型，并对2008年试验期间冠层上方碳通量特征进行了模拟，试验分析和模拟的主要结论如下：1。

With the development of computer technology, a variety of file data also change the size of the growing size of the USB has been far less incompetent at every turn on the GB of file storage and exchange of tasks.

随着计算机技术的发展，各种文件数据的体积也变的越来越大，体积较小的优盘已远不能胜任动辄上GB的文件存储和交换任务。

The last big question on Hollis's research agenda -- whether the cells will reset after having fired -- may not even matter in the group's latest vision for a handheld biosensor: a proposed optical-electronic box would read the photons emitted by a swappable and disposable biosensor chip, which would cost just a few dollars.

在霍利斯的研究日程表上，最后一个大问题在于细胞在发光后是否能够重新设定，按照研究小组最近对手动探测仪的设想，这个问题可能并不太重要：人们拟利用光电盒读取可交换的一次性生物探测芯片发出的光子，而光电盒只需要花费几美元。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
