First, in the composite hypothesis testing, circular dispersion error which is more practicable than horizontal and vertical error is used to discuss some problems of the dispersion of impact points; and the critical area of decision in the dispersion problem is analyzed; the specific expression of Bayesian risk is worked out, which ameliorates the method that only can get the approximate solution by calculating numerical integration.

由此，本文主要应用Bayes方法对以下几方面进行了探讨：首先，在复杂假设下，本文利用圆散布误差这一精度指标对落点散布鉴定问题进行研究，它比以往所用的纵、横向偏差精度指标更具现实意义；分析了此鉴定问题的决策临界区域；给出其Bayes风险的具体表达式，对用数值积分进行近似求解的方法进行了改进；在此基础上，通过极小化试验的风险确定最优试验数n，并讨论了决策中犯两类错误的概率，给出了验前信息的表示。

In order to be convenient for management, Internet has been divided into a great number of small parts, namely autonomous system .

出于管理的需要，当今的Internet被划分为众多的小的区域，即自治系统。

The key points of sensorless technology in PMBLDCM are to study a method which can detect rotor position accurately by simply method in whole speed range. After analyzing current sensorless methods of the PMBLDCM, it is found that those methods are successful at middle and high speed, but they often fail to detect rotor position at low speed when the back electromotive force is small or zero.

纵观目前的永磁无刷直流电机的无位置传感器控制方法，比较成熟而可行的方法多集中于电机在中高速区域运行时，能够较准确估计转子位置；电机处于低速、极低速、静止状态时电加热管，因为反电动势幅值较小或者为零，而无法正常工作。

There, Endeavour will execute a slow backflip maneuver, presenting its belly and other areas of its heat protective tiles to station residents Barratt and Padalka, who will use digital cameras equipped with 400 and 800 millimeter lenses to acquire detailed imagery.

在那儿，奋进号将完成小速度机动，将翻转机腹和机身其他区域的隔热瓦面向位于空间站上的Barratt 和Padalka，他们将使用400和800毫米镜头的相机对航天飞机进行详细拍照。

A new regional remote image fusion method based-on wavelet transform is presented.

提出了一种基于小波变换的区域遥感图像融合方法的改进。

It is one of the most suffered project sites in the earthquake. People there are desperately in need of medicines, tents, beddings, and daily appliances.

这是小母牛川渝区域项目点中遭受"512汶川大地震"破坏最为严重的地区之一，现任急需药品、帐篷、棉被、生活用品等。

The development of cladistic biogeography has three directions. While improving the methods, the methods should be used in more organism species and be used in the lower level area relationships.

目前支序生物地理学的发展有以下3个方向：不断完善方法体系；在更多的生物类群和地理范围得到应用；在更小的区域范围方面的应用。

Besides choose the bath that contains salicylic acid answers blain of small red blain with the product that protect skin besides, it is particularly advertent and easy that you still need the cleanness of area of long blain blain, not allow especially Yi Qingjie's back.

除了选用含水杨酸的沐浴和护肤产品应对小红痘痘之外，你还需要特别留意容易长痘痘区域的清洁，尤其是不容易清洁的背部。

Baldwin's equation gives the depth of the zone of brecciation for such a crater as about 75km.

基于测量过的小环形深坑的深度，鲍德温的等式给出brecciation区域的环形深坑的深度大约应为75公里。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.
