作者采用绝对均值法和莱因达法分别对三组实测数据进行坏点数据的剔除处理，对处理结果的分析对比表明运用绝对均值法剔除动态测试数据中的坏点数据比莱因达法效果更好。

Compared with traditional invasion detection system has a lot of advantages to invade the detection system distributed: Distributed IDS is that a lot of measures the land to different data sources, adopts different measuring algorithms, measure together, cooperate and deal with, has improved the accuracy measured ; But distributed IDS can be used in the extensive network environment; Distributed IDS may use the special package to be punish and audit datum safely, help the system to be produced and invade the rule of measuring and produce and unusually measure models ; Distributed IDS analyses the behaviors of a lot of control points in coordination, may measure out and attack distributed in coordination ; The measuring of distributed IDS right a certain control point can be regarded as the early warning of other check points .

分布式入侵检测系统跟传统的入侵检测系统相比有很多优点：分布式IDS是多个检测域针对不同的数据来源，采用不同的检测算法，共同检测，协作处理，提高了检测的准确性；分布式IDS却可以用于大规模的网络环境；分布式IDS可以使用专门的组件处理安全审计数据，帮助系统生成入侵检测规则和生成异常检测模型；分布式IDS协同分析多个监控点的行为，就可能检测出分布式协同攻击；分布式IDS对某个监控点的检测可以作为对其他检测点的预警。

For example of the Shiyang River Basin along the Hexi Corrider,in Gansu province,made the imitial research of the major crop water production function and irrigation schedule optimal model,the results are following: 1Based on the related experimental datum gathered,drawing the relationship curve of several major crop yield and evapotranspiration,such as spring wheat,spring wheat-corn strip field,seed melon,sweet melon,cotton and flax and so on. The result shows these there:linearity and non-linear between crop yield and evapotranspiration.

本研究以甘肃省河西走廊石羊河流域为例，对其主要农作物的水分生产函数及灌溉制度优化模型作了初步研究，取得了以下成果： 1 根据收集的有关试验资料，绘制了春小麦、春小麦-玉米带田、籽瓜、白兰瓜、棉花和亚麻等几种主要农作物产量与耗水量的关系曲线，结果表明，产量与耗水量之间一般存在着线性与非线性的关系。

As mentioned Live/Google maps use a Mercator projection, but although their datum is based on WGS84, they use a sphere instead of an ellipsoid.

上文所说Live Map / Google Map 使用墨卡托投影，但虽然他们的大地基准应该是基于WGS84的，他们用球体模型替换了椭球体模型。

Because heart-sound is a highly nonstationary signal, this paper presents the application of adaptive filter method to the elimination of noise, and at the same time, employs the datum of heart-sound plot as the reference noise.

针对心音信号的非平稳性，提出了以自适应滤波方法来消除干扰，并提出了以心音间隙期的样值作为参考噪声的分析方法。

By analyzing the datum, it is necessary for us to set up the fund for motor vehicle insurance.

本文通过对数据的分析，说明建立我国机动车辆保险赔偿基金十分必要。

Because only two parameters were used and the datum was small, the moving vehicles in the frame were tracked and located the position quickly.

该算法处理参数少，数据量小，因而能够及时跟踪到车辆在图像中的位置。

This is especially a problem on multiprocessor systems where more than one process may be accessing a datum.

这尤其是在多处理器系统方面的一个问题，超过程序可能存取一个资料项目哪里。

Input nodal point s can represent each datum so it is a must to find accurate data resources. If there are too many false or irrelevant data in the data resources, the proper training of the network[12, 13] will be obstructed.

输入节点能够代表每个数据，所以要弄清楚正确的数据源，如果数据源中包含大量虚假或不相关的数据，那必将妨碍对网络的正确训练。

All kinds of solutions including precision estimations can be transformed each other by means of the normal equations and the datum conditions.

经典自由网平差、附合网平差、普通秩亏自由网平差、加权秩亏自由网平差等都可以用附有条件的间接平差统一表示。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
