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。

Rule-based and reusebased method is adapted in our system to develop applications. Rules are used to define geometric representation of geographic objects, spatial relationships among geographic objects and map design rules. Reusability is realized through object's inheritance and encapsulation. The basic function related to GIS has been implemented in OOGDB's basic class base. Application related function can be implemented in sub-classes of basic classes and some of basic class' function can even be overloaded.

GIS应用系统的开发采用基于规则和基于重用的方法进行，规则用于定义地理对象的几何表示和空间关系以及地图构造的规则等，重用是通过面向对象的继承和封装机制实现的，GIS实现了一个基本的类库，它完成基本的空间处理和操作，用户通过定义这些类的子类重用类库提供的功能，并增加与应用系统有关的特殊功能，用户甚至可以通过重载修改某些类库的功能。

Results showed that the CO2 absorb ability in the eight Crop systems net productivity process was 4 032 366ta^(-1); the amount of CO2 outlet in the soil was 3981753ta^(-1), less than the CO2 adsorb ability, so that the whole crop system was a weaker carbon sink process in the atmosphere. The continue planting species such as Rice, sugarcane, cassava, and melon crop or high haulm crops have the characteristics of annually crop net productivity CO2 absorb ability bigger than soil CO2 outlet and this systems had bigger carbon sink function ability; the short haulm crop systems of peanut, soybean, flowers, and vegetable annually crops net productivity CO2 absorb ability less than soil CO2 out let, but also carbon sink source. The CO2 absorb ability of fruits and economic parts above ground bigger than that which growth under ground. Except of the CO2 absorb ability less than the soil CO2 outlet in the peanut during growth in procreate period, the other seven crops CO2 absorb ability were bigger than that soil CO2 outlet during procreate period. Most of crops during growth in procreate period had carbon sink function ability, and only in barren period showed the carbon source function phenomenon.

结果表明：2005年广州市8种农作物系统作物净生产力吸收CO2 4032366ta^(-1)，其土壤CO2排放3981753ta^(-1)，吸收大于排放，对大气CO2而言，整个农作物系统是一个弱的碳汇；水稻、甘蔗、木薯和果用瓜4种连作或高杆作物系统每年作物净生产力吸收CO2量大于土壤CO2的排放量，系统具有较大的碳汇功能，花生、大豆、花卉和蔬菜4种矮杆作物系统每年作物净生产力吸收CO2量小于土壤CO2的排放量，系统起着碳源作用；果实或经济产量生长在地上部分的作物其单位面积吸收CO2能力比果实生长在地下的作物大；除花生在生育期间生物量吸收CO2量少于同期土壤排放以外，其余7种作物在生育期间生物量吸收CO2的量大于同期土壤排放，大多数农作物在生育期间具有碳汇功能，在撂荒期才体现碳源作用。

Because we mainly involve visual fields of medical science , have placed more contents on the development in the field of medical image of visual technology and argumentation used. Second part It is the visual technology knowledge, the generalization in such respects as the basic principle , basic functions, function store and three-dimensional animation technology to OpenGL ,etc. The realization of the system using OpenGL functions finish that three-dimension demonstration. The third part It is number value that calculate knowledge, three-dimension rebuild technology is it is it is it punish to fit to go on to need, the research of interpolator technology that cant leave, So this part has quoted the Hermite function principle , define cubic Hermite function to begin, calculate the differential coefficient among them draws cubic spline again.

由于我们主要是涉及医学可视化领域，所以将更多的内容放在了可视化技术在医学影像领域的发展与应用的论述；第二部分是可视化技术方面的知识，主要对 OpenGL 的基本原理、基本功能、函数库及三维动画技术等方面的概括，在系统实现时就是通过调用 OpenGL 函数库实现三维显示的；第三部分是数值计算方面的知识，三维重建技术需要进行拟合处理，离不开插值技术的研究，所以这一部分从埃尔米特函数原理开始讨论，引入三次埃尔米特函数，进一步计算时又引用三次样条函数。
