| 1. | Estimating structural safety of existing container crane
现役集装箱桥吊结构安全评估 |
| 2. | The most eye - catching things at this port are these bridge cranes
港区里最显眼的就是这些桥吊。 |
| 3. | The design and construction of boxed cofferdam of the zhujiang bridge
珠江特大桥吊箱围堰设计与施工 |
| 4. | Combining with a concrete subject , the first chapter presents the communication in plc control system in crane will be studied and why must it be studied
而无论是单台桥吊内部的控制，还是对于多台桥吊的远程监控，所要研究的都是它们的通信问题，即内部通信和外部通信。 |
| 5. | In the past , the study and design were centered on the interaction of the wharf and yard , while the crane was considered as stationary , passive and of secondary importance
以往集装箱码头设计研究过程中，比较注重码头，堆场的能动性，而将桥吊放置在静止，被动的从属地位。 |
| 6. | By analyzing the hardware and software of plc control system in crane , the second chapter makes clear that the objects of communication are plc and inverters . profibus is used in plc control network in the subject
第二章首先从硬件和软件两方面具体的分析了单台桥吊的plc控制系统，指出了内部通信问题所涉及的对象是plc与变频器之间的通信。 |
| 7. | Container wharf is a large system , in which wharf , container yard and quayside container crane are the three most important factors , and their proper configuration will determine the handling capacity and efficiency of the wharf . .
集装箱码头是一个大系统，在这个系统中，码头、堆场、桥吊，是三个最重要的要素，合理的配置决定了码头能力均衡性和效率。 |
| 8. | This thesis draws to the conclusion by the methods of model system ? experiment analysis and comparison that the latter one is of more theoretic significance and deeper application background . then we can say the attribute theory is superior to neural network method in the domain we concerned
这表明，为解决桥吊的状态监测与安全评估的系统建模计算机实现的问题，属性论方法提供了一个比神经网络更优越的新模型和新思路，具有理论意义和重要的应用价值。 |
| 9. | Long - term practice shows that handling capacity can more directly and effectively demonstrated if the crane configuration is studied as primary parameter , while the size of yard , other supporting facilities and equipment could be subsequently determined . a preliminary research was conducted based on this concept , and no literature on this topic was found which slows my study progress
通过长期实践，我发现如果以桥吊的配置作为一个码头能力研究点，能更简洁，更有效地反映出其能力大小进而对码头，堆场大小，设计具有很强的指导意义，其它相关配套设施、设备就能以其而定。 |
| 10. | - the focal point of this paper is studying the problem of cargoes ? weight measurement , besides the component of mechanical system , the component and control of electric - control system , the full - digital dc speed adjustment system and the hardware and software design of plc control system . this paper puts forward the project of current static measurement method and corrects it with acceleration dynamic measurement
本文除分析介绍了集装箱桥吊的机械系统组成、电控系统的组成及控制、全数字直流调速器以及plc控制系统的软硬件设计外，重点研究了集装箱装卸桥中的货物称重问题，提出了应用电流静态测量法的称重方案，并且采用了加速度动态测量法对其进行动态校正，在实际应用中取得了令人满意的效果。 |
