Since the 1960s,the leading shipbuilding countries begin to study on the ship condition monitoring and trouble analysis, Nobodys engine-room shipping on duty appeared .certainly the condition monitoring and trouble analysts system also meets some question ,such as: only give alarm or show the actual value of the parameter, does not possess the function of analyzing and giving operator the direct suggestion function about the complicated trouble reason , Only monitor the present running conditions, does not possess the function of predicting equipment future and run reliability though trouble analysis technology makes good progress in these yeas, onboard the ship is still rare .aiming to improve the shipping safety, this paper make some research work on the ship engine-room, the main innovation are as follows:Firstly, this paper introduces and analyzes the research work and current situation on the condition monitoring, trouble analysis and safety assessment .especially in the maritime fields .

船舶机舱系统结构复杂，故障源多，征兆参数丰富，故障与征兆之间常常不存在简单的对应关系，而是相互影响，关系错综复杂。60年代以来，世界上先进的造船国家都相继开展了船舶机械状态监控和故障诊断的研究，出现了无人值班机舱船舶，但仍存在不足之处，如：只给报警提示或显示参数的实际值，不具备对复杂故障的原因分析并给操作者以直接的提示或建议功能；只监测当前的运行状况，不具备预测设备未来运行可靠性的功能；尽管近年来设备故障诊断技术得到了很大的发展，但真正能成功应用于实船的尚不多见。本论文以船舶机舱为对象，以提高船舶营运安全性为目标，来研究船舶机舱的安全控制技术，主要内容如下：首先，介绍和分析了状态监测、故障诊断和安全评估的研究内容和现状，尤其是在船舶领域的研究近况。

在此基础上，提出了航空发动机全包线内故障诊断的方法，并使用Visual C++编程语言，开发了故障诊断软件模块，可以实现全包线内的在线故障诊断功能。

On the model with reasonable isomorph suppose,a model-based diagnosis is used in program debbuging for logic errors,and compare this model to the other classical models on its advantages.

在此模型上，使用合理的同构假定，运用基于模型的诊断方法对程序进行逻辑错误的诊断，并与经典的诊断模型作了比较。

Secondly, the monitoring and diagnostic integration concept was proposed for the hybrid system, based on this assumption, the monitor and diagnosis technology for running process of DMF recovering vaporizer was analyzed. The hybrid Petri nets information model describing the miscellany characterization for production process and controller model for diagnosis and decision were given. The combined propagation condition between equipment failure and heavy disturbance of continuous parameters was also discussed. The simulation results suggest that the methods in this work are valid.

其次，论文针对混杂系统提出了监控与诊断的集成概念，在此基础上进行了DMF回收蒸发罐运行过程的监控与诊断；建立了描述生产过程混杂特性的HPN信息模型和用于诊断决策的控制器模型，探讨了设备故障和连续参数大的扰动的合成传播问题，仿真结果说明了本文设计方法的有效性。

Secondly, the power system fault diagnosis analytic model which use both protect andswitch action information is proposed in this paper, it can be described as 0-1 integerprogramming with nonrestraint, reshut break is introused in the analytic model and introducethe contribution factor to the protect, this model solve the fault diagnosis problem in which theprotect information is lack in a certain extent, and present the experienced formular which isused to decide all kinds of protect contribution factor.

然后，提出同时利用保护和断路器动作信息的电力系统故障诊断的解析模型，其可以描述为一个无约束 0-1 整数规划问题，将重合闸引入故障诊断的解析模型并且对保护引入贡献因子，给出确定各种保护贡献因子的经验公式。这种模型在一定程度上解决了数据信息不完整时的电力系统故障诊断问题。

Based on adequate survey to faults of sodium pump for The China Experiment Fast Reactor, in order that the advanced diagnosis methods are used in the sodium pump which is under fabrication, different methods of fault diagnosis system of sodium pump are designed and programmed; and the principal component analysisis used to fault diagnosis system of main coolant pump in a nuclear power station. The feasibility of fault diagnosis systems developed have been proved by simulation results.

本课题对中国实验快堆钠泵的故障进行了研究，把先进的诊断方法应用到正在制造中的钠泵上，设计和开发了不同方法的钠泵的故障诊断系统；同时也应用主元分析方法，建立了某核电厂的主冷却剂泵的故障诊断系统，仿真实验证明了以上三个系统的可行性。

The "spiculation"sign raised accurate rate of the diagnosis by 11.8%.Conclusion Real-time three-dimension ultrasound is a good supplement of two-dimension ultrasound.It can give more diagnosis information of the breast mass,especially to the small mass which can not be diagnosed definitely by two-dimension ultrasound.To analyse the characteristics of coronary section will improve the diagnosis accurate rate of the breast cancer.

三维超声是对二维超声检查的一个补充，它为诊断乳腺肿块的良恶性多提供了一些观察的指标，尤其对那些在二维图像上不能明确诊断的小肿块，加用三维扫查，注重分析冠状切面特点，有助于提高诊断的正确率。

Breast cancer is the fourth leading cause of cancer death for Taiwanese women. X-ray mammography is currently the most effective method for an early diagnosis of the breast cancer. The existence of spicules is one of most important visual signs for breast cancer diagnosis. Spiculation is a stellate distortion caused by the intrusion of breast cancer into surrounding tissue. In general, malignant tumors appear with rough and complex boundaries or contours, whereas benign masses present smooth, round, or oval contours.In this paper, we present a technique to detect the contours of spiculated lesions from the regions of interest in a mammographic image.

中文摘要乳癌是是我国妇癌症死亡主因的第四位，乳癌诊断程序中，乳房X光摄影为临床上医生诊断乳癌的利器，在诊断乳房摄影肿瘤的影像时，可用特徵决定为良性或恶性肿瘤，良性肿瘤通常会呈现圆滑的特徵，而恶性肿瘤则呈现星状或不规则不平滑特徵，这种星状或不规则不平滑特徵组织，称为星状物肿瘤，指的是肿瘤周围的乳腺组织，因星状物往外侵犯的关系造成的变形，星状物的存在是恶性肿瘤判断的依据。

objective to study mri diagnostic value on multiple sclerosis.methods mri examination data of 31 patients with multiple sclerosis were analysised retrospectively.results total 184 lesions were detectived in 31 patients.most lesions were located on white watter area beside the lateral ventricle,and a few lesions were located on the spinal cord,cerebellum,brain stem and corpus callosum.the shape of lesion can be circle or ellipse.the lesion showed as slightly long t1 and long t2 signal.the acute stage lesions can have enhancement.conclusions ms have characteristic findings on mri image.mri can show the patholoic changes,and provide strong evidence for clinic diagnosis of multiple sclerosis.

摘 要］目的：探讨多发性硬化（muliplle sclerosis，ms）的mri特征表现及其诊断价值。方法：回顾分析31例临床诊断为ms患者的mri检查资料。结果：31例共发现病灶184个，病灶于侧脑室旁白质区、半卵圆中心及皮层下区最多见，其次见于脊髓小脑、脑干及胼胝体，部分可见视神经受累，病灶呈卵圆形或圆形稍长t1、长t2信号，矢状位像见病灶与侧脑室垂直，急性病灶增强扫描有的可呈结节状、环状或斑点状强化。结论：在mri图像上ms有特征性表现，mri能反应ms病理变化，为临床诊断ms提供可靠依据。
