I am still hesitating on spending much time on it because I am doing some other compusory projects as well. Yes, you are right. From struggling on the papers, we can learn a lot by ourselves. Sorry for the massy words. I cannot type Chinese in labs.

我这次做毕业论文也顺便自学了一些相关的东西，好好做一次论文下来还真是在好几个方面都收获不少，真羡慕你这样专们学习的呀，虽然功课重一些，作业所一些，但到底能够更加深入，是多莫难能可贵的机会亚！

A non-linear programming model was established which considered both assignment of machine and time arrangement for the production environment with multi-stage, multi-machine and different refining number. The hybrid intelligent optimal scheduling method was presented which included assignment of machine based on expert system, neighborhood search based on man-machine interaction, and time optimization based on model conversion.

针对多阶段、多设备以及精炼工序重数不同的炼钢连铸生产调度问题，建立了综合考虑工序设备指派和作业时间安排的非线性规划模型，提出了基于专家系统的设备指派、基于人机交互的邻域搜索与基于模型转换的时间优化相结合的三阶段炼钢连铸混合智能优化调度方法。

My father encouraged me to redo my homework.

Andy: I'll just reformat my hard drive and reinstall the operating system.

安迪：我只想将硬碟重新格式化，并且重灌作业系统，这样就可以解决了。

The experiments showed that both rotary belt cutter and the jagged chain cutter can realize high speed cut with high ground speed, the former cut speed and operating speed can reach 17 m/s and 15 km/h separately, and the latter can reach 7 m/s and 13 km/h responsively.

试验表明，回转带式切割器和齿形链式切割器均可实现高速切割和高速作业，前者(来源：ABC55论文网www.abclunwen.com)的切割速度和作业速度分别达17m/s和15km/h，后者的切割速度和作业速度分别达7m/s和13km/h；工作平稳，割台振动小，割茬整齐，无撕裂、漏割、重割和堵刀现象；适于收割小麦、水稻等细茎秆作物和牧草。

Based on the principle of ship statics, the authors deduce a method to calculate the metacentre height and the inclined angle when a heavy cargo is loading or unloading by a derrick on board the ship.

基于船舶静力学理论，推导了重大件货物装卸过程中船上重吊在任意位置时船舶稳心高度及横倾角的计算方法，分析了影响船舶稳性及横倾的基本要素，并给出了调整船舶横倾的具体方法，为船方掌握重大件货物作业中船舶稳性及横倾的变化规律并采取恰当的安全措施提供了理论依据。

The steel armored electric cable logging truck owner asked that the truck should consists of electric cable driving machine, goose neck guider, winch, hydraulic driver, depth detector, weighing display, instrument display panel, and data collection system. It can solve the problem of pulling force for the down hole instrument in horizontal, sticky oil and high pressure wells. The practice shows that it is a device with high efficiency, low cost, strong suitability to environment, reliability and safe.?

钢铠电缆测井车主要由驱缆器、鹅颈形导轨、绞盘、液压驱动、测深、指重装置、仪表显示操作盘及数据采集控制处理系统等组成，能解决水平井、稠油井、高压油井等特殊井类在测井过程中仪器下行牵引力的问题，是一个作业效率高、测试成功率高、成本低、适应环境能力强、作业安全可靠、具有环保效益的新技术。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
