The process of feature extraction is to transform the eradiate noise signal to different feature space and extract the feature vectors that reflect the category of the input sample. The extracted features are the input modes to the classifier. Through the inspecting, the author selected three methods of eradiate noise's feature extraction.

本文作者经过考察，采用了三种前期研究中较为有效的水下目标特征提取方法——基于功率谱估计的线谱特征提取方法、基于小波分析的不同频段内能量特征提取方法和基于水声信号分维特性的特征提取方法。

A new algorithm of low bit rate image compression was proposed. Firstly, the edge informations of the input image were detected with SUSAN operator, then the detected edge informations were en hanced with edge enhancement method. Finally, the enhanced edge informations were added to the decoded input image to form the final compressed image.

提出一种新的低比特率图像压缩算法，该算法首先利用SUSAN算子检测出输入图像的边缘信息，然后利用边缘增强方法对边缘信息进行增强，最后将增强后的边缘信息和解码后的输入图像相加形成最终的压缩图像。

Taking the sediment discharge of the Lijin Hydrometric Station as input, increment of area and migration of shoreline of the present subdelta as output, by using the model of linear control system which is individual input and individual output, the author built the dynamic prediction model on the development and evolution of the present subdelta, and then predicted its development and evolution, and analyzed the influences of sediment discharge of the river on its development and evolution.

首先，以黄河利津站的来沙量为输入、现行黄河亚三角洲的面积和岸线增长为输出，采用单输入、单输出的线性控制系统模型建立了现行黄河亚三角洲发育演变的动态预测模型；然后，利用该模型对现行黄河亚三角洲的发育演变进行了预测，并据此分析了黄河来沙量对黄河亚三角洲的发育演变影响。

The organic materials of source rock are mainly from terrigenous plants combined with abundant aquatic organisms input, which reflects the mixed-source of organics input of terrigenous plants and hydrophilous alga.

烃源岩有机母质均以陆生高等植物输入为主，也有水生生物的输入，反映原始母质具有水生生物和陆源高等植物混源的特征。

On the base of the analysis about the cause why this type of systems is hard to be controlled a new FNN, the FNN based on hyper-cylinder clustering, is presented. By comparison with the FNN based on hyper-sphere clustering, for any sample to be clustered, the FNN based on hypercylinder takes not only its input sample but also its output value into consideration. And so it is impossible for any two samples with'close'input samples and'estranged'output values to be clustered in the same cluster.

借助于对非线性系统模型Ⅱ不可逆情形下难以控制原因的分析，提出了基于超柱体聚类的模糊神经网络，与基于超球聚类的模糊神经网络相比，这种模糊神经网络在聚类时不仅考虑样本中的输入向量，也考虑样本的输出值，因此不会将输入向量较接近而输出值差异较大的两个样本聚为一类。

The result indicates that the intracortical synaptic input was unchanged, but the thalamocortical synaptic input was depressed by sensory stimulation and this depression recovered with a time course that matched that of the recovery of sensory responsiveness.

结果表明，电刺激诱导出的皮层—皮层突触反应不受持续的触须刺激的影响，而电刺激诱导出的丘脑—皮层突触反应则由于持续的触须刺激而减小，而且突触反应的恢复时程与皮层细胞适应恢复的时程类似。

For systems with input saturation constraint and invertible static input nonlinearity, a two step generalized predictive control strategy is adopted.

对存在输入饱和约束和输入可逆静态非线性的系统，采用两步法广义预测控制策略。

For systems with input saturation constraint and invertible static input nonlinearity, a two step generalized predictive control strategy is adopted.

摘要对存在输入饱和约束和输入可逆静态非线性的系统，采用两步法广义预测控制策略。

Free version has this software a characteristic, it is every when stepping on a space, can play a draw a frame round of a visa, need input visa is piled up namely meaningless letter, its input need not tire of irritatedly, this coolie to network operation ace be too tired, too undeserved oneself go doing.

这软件免费版本有个特点，就是每踩一个空间的时候，就会弹出一个签证框，需要输入签证码--也就是无谓的字母，需要不厌其烦地输入，这苦力对于网络运营高手来说是太累了，太不值得自己去做的。

It is very important to set up a scientific appraising system for input method not only for justicial evaluation, but also for bringing out perfect Chinese charater input products.

建立科学的输入法评价体系，不仅可以指导编码发明者形成科学的汉字编码方案，而且可以帮助输入系统设计人员对输入法产品进行客观的自我评价，从而推出符合国家规范的更好的输入法产品。

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.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。

On one hand, there are discussions with the works council and union about extension of short time working up to the end of September.

一方面，有讨论，工程理事会和联盟关于延长工作时间短至9月底。
