Because there are the characteristics of uncertainty and mixing meta-pixels in the remote-sensing images, the classical fuzzy c-means method has a low accuracy in the remote-sensing image clustering. This paper improves the fuzzy c-means method. And it adds a-priori information into the patterns to change the method as a semi-supervised clustering. In the clustering process, the unlabelled patterns compare similarities with the labeled patterns, and then the accuracy of the algorithm can be increased.(3)The paper proposes an interactive learning-based image mining in remote sensing.

由于遥感图像各类别在特征空间中散点图的分布的特点，本文对传统的FCM聚类算法进行改进，并且加入先验信息之后，将原来的非监督的聚类变成一种半监督的聚类方法，通过与已标签的样本进行相似性比较，能有效地提高聚类算法的准确度。

Methods:The MSCT datas of 65 mechanical intestinal obstructions confirmed by operation and pathology were collected and reconstructed with multiplanar reconstruction technique,including 43 cases underwent plain scan;the remaining 22 cases underwent plain and contrast-enhanced scan.Results: Contrast to operation and pathology,there were 25 adhesions,24 neoplasms,5 bowel torsions,5 bezoarhs,4 intussusceptions,2 Crohn's diseases in 65 mechanical intestinal obstructions,the diagnostic accuracy of MPR in mechanical intestinal obstruction was 100%,and the accuracy of the pathogeny was 84.6%.

以往在肠梗阻的诊断中应用最多的为腹部X线平片，但因其信息量不足，对大部分病人不能提出肯定诊断，且对梗阻的病因及病变肠管的血供都无法判断。16层螺旋CT在肠梗阻的诊断中具有明显优势，快速、薄层扫描可得到高质量的各向同性后处理重建图像，在显示肠壁、肠腔和周围结构等方面具有较大优势，有利于肠梗阻的梗阻部位及病因、并发症的诊断。

As a kind of precisely inertial instrument, the orientational accuracy of the north-seeking system is decided by the accuracy of the gyroscope it used to a large extent.

在本文中我们研究的这种磁悬浮陀螺寻北仪，就是通过采用自适应控制方法，利用磁悬浮技术实现对单自由度陀螺框架轴的无摩擦悬浮，旨在得到更高的寻北精度，同时提高定向速度。

And Finally according to theprogramed algorithms, simulation and experimental stitchings are porformed for testing thealgorithm accuracy. Results show that, the comprehensive errors of theretical andexperimental wavefront stitchings are less than 10~(-6)λand than PV/10 (where PV refering towavefront peak-to-vally value), respectively. Furthermore, experimental research isconducted on the influence of stitching accuracy by sub-aperture overlapping area andstitching modes, with subaperature real-time stitching test for large plano-optic broughtabout.

第三，对编写的算法程序进行了模拟拼接实验和实际拼接实验，测得该算法程序的精度为：理论拼接波面的综合误差小于10~(-6)λ，实际拼接波面的综合误差小于PV／10(PV为被测波面相位峰谷值)；在此基础上，又就子孔径重叠区域大小和拼接模式对拼接精度的影响进行了实验和分析，实现了大口径光学平面的子孔径实时拼接检测。

The high accuracy time delay estimation of positioning signals is verified through the analysis of the experimental results, which shows that the GPS sonobuoys meet the requirements of the system performance, featuring very high measurement accuracy.

经过湖试和海试的检验，GPS声纳浮标能够满足系统指标要求，具有很高的延时测量精度。

Because the variation of the light source and other errors related to light intensity are not so critical for the measurement in this system and some 1/4λ wave-plates affect on the other wavelengths is very little, the retardance can be measured in high accuracy and high repeatability. In principles, the system accuracy can measure any retardance, and can be used in characteristic spectrum analysis of other phase retarders.

由于此系统可忽略光强的波动及与光强有关的误差，且1/4λ波片对多波长测试误差的影响很小，故其有很高的精度和可靠性，可以测试其精度范围内的任意小延迟量，亦可对其他光学相位延迟器件进行光谱分析。

The clinical therapeutic strategies were changed in 22 cases due to the results of PET/CT,and the influence rate of PET/ CT was 28.6 %(22/77).Conclusion PET/CT can detect the primary lesions, recurrence and metastasis of gastrointestinal tumor with high sensitivity and accuracy. 18F-FDG PET/CT imaging has increased accuracy of the diagnosis, staging, restaging for gastrointestinal tumor.
