In a real application of the optical fiber sensor, there is no spark or discharge, but convenient way of building long-distance measurement.

与传统传感器相比，它具有灵敏度高、响应速度快、抗电磁干扰、耐腐蚀，在测量过程中自身不会出现火花、放电，易于实现远距离在线检测等优点。

At present there exit many problems on pulverized coal combustion technology, for example, poor flame stability (including for low-grade fuels and low load), low combustion efficiency, serious pollution, furnace slagging and high temperature corrosion, etc. Therefore solving these problems is very important for pulverized coal-fired utility boilers.

目前我国煤粉燃烧技术中存在的主要问题是燃烧不稳定（包括劣质煤稳燃和低负荷稳燃）、燃烧效率低、污染严重、结渣和高温腐蚀问题等，解决这些问题是煤粉锅炉安全、稳定、高效和清洁燃烧的基本保证，也是今后煤粉燃烧技术的发展方向。

As the important accessories of seawater pipes system, seawater pump and valve usually made of tin bronze and silicon brass were not able to meet the high reliability requirement for seawater pipes, because they were liable to serious electric coupling corrosion as they were coupled with the currently popularized B10 alloy in sea water.

海水泵阀等附件是海水管系的重要部件，国内常用锡青铜、硅黄铜制造，与目前推广使用的B10合金在海水中偶合时，电偶腐蚀较重，不能满足海水管系对高可靠性的要求。

Because of the high sand, high water content, high salinity, high temperature steam heavy oil exploitation, mining and strong polymer injection corrosion media environment factors, piston pump wells pump an average of more and more short-cycle, and some do not even to the required 30 days on the pump seized, severely affected by oil field development.

由于高含砂、高含水、高矿化度、高温蒸气稠油开采、注聚合物开采及强腐蚀的介质环境等因素影响，柱塞泵井平均检泵周期越来越短，有的甚至不到30天就需要检泵，严重影响油田开发。

Corrosion products formed by these reactions can prevent normal valve operation and can become embedded in the elastomeric stem tip, preventing the valve from making a complete seal.

这些反应产生的腐蚀产物会阻止正常的阀门运转，深入到人造橡胶阀杆顶端，造成阀门不能完全密封。
