Based on the characteristics and the demands of synchronization, a single nero forecast controller was presented, which was designed to eliminate synchronization error of upset force in flash butt welding. A press feedback loop was designed to solve the problem that it is uneasy to assemble force sensor in flash butt welding.

针对于大截面钢坯闪光焊顶锻阶段的特点和同步要求，提出了一种基于单神经元的同步误差预测控制方案，用于消除闪光焊顶锻过程中的系统之间顶锻力的同步误差；方案中采用液压系统压力反馈的方法解决了闪光焊中不方便安装里传感器的问题。

The flash butt welding parameters, such as flash model, flash velocity and initial clamp distance were analyzed quantitatively. The rule of heat producing and temperature distribution by different welding parameters in coupling with electric and heat was researched.

对钢轨闪光焊过程中闪光模式、闪光速度及起始夹具距离等规范参数的变化规律进行了定量分析，揭示了电热耦合过程中不同焊接规范组合下的产热规律和温度分布规律。

The results of the experiments show that the model simulated the actual process by flash butt welding accurately.Using the electric-heat coupling model built, this work discussed how to get the temperature field with different welding parameters and its effect conditions.

对电阻闪光对焊过程中伸出长度、闪光模式、闪光速度等规范参数的变化规律进行了定量分析，揭示了电热耦合过程中不同焊接规范组合下的产热规律和温度分布规律；利用所建立的闪光对焊热力耦合模型计算了顶锻过程中顶锻接触行为的主要影响因素与规律。

Now, the technology of flash welding has been applying in the engineering of rail welding progressively. The temperature field of flash welding plays a crucial role in the quality of welding joint, so the study of welding temperature field is significant to ensure the traffic safety and quality of welding and reduce the cost of welding.

目前，闪光焊技术在我国钢轨现场焊接工程中的应用正日益增多，由于钢轨闪光焊的焊接温度场对接头质量起着决定性的作用，因而开展钢轨闪光焊温度场的研究，对于控制焊接质量，降低焊接成本，提高列车运行安全具有十分重要的意义。

For many years researchers have been trying to develop a synthetic material with the same light-scattering properties as an opal, by etching patterns into various materials.

B 选项对应于文章第一段，也提到了宝石闪光成分存在使得它可以闪光。 C 选项，第二段提到了这一点。 D 选项，第一段提到是发明的塑料可以用于制作油漆的闪光替代品，而不是蛋白石本身。因此，答案为 A 选项。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。
