Have expected much the water level of the steam dome like this.

这样对汽包水位要求就更高了。

And this course of change of water level of steam dome caused to perturbation of water flow can pass experiment test and receive the accurate mathematics model with data processing , can design the routine controller to control like this, and can reach very good result.

而给水流量的扰动造成的汽包水位变化这一过程可以通过实验测试和数据处理得到精确的数学模型，这样就能够设计常规控制器来控制，并能达到很好的效果。

The majority in these accidents is improper in control because of the water level of the boiler were caused, can see the importance in the equipment control system of the boiler of control of water level of steam dome of the boiler.

这些事故中的大部分是由于锅炉水位控制不当引起的，可见锅炉汽包水位控制在锅炉设备控制系统中的重要性。

Then, use the fuzzy control theory and design a boiler steam dome water level fuzzy control system, have realized the fuzzy dynamic feedforward , through making emulation in simulink, have reached better control effect.

于是，应用模糊控制理论，设计出一个锅炉汽包水位模糊控制系统，实现了模糊动态前馈，通过在simulink下仿真，达到了较好的控制效果。

And this course of change of water level of steam dome caused to perturbation of water flow can pass experiment test and receive the accurate mathematics model with data processing , can design the routine controller to control like this, and can reach very good result.

并通过常规三冲量PID仿真与模糊控制仿真进行了一系列对照，结果证明对于那些过程复杂，具有时变性和明显滞后以及难以取得精确的数学模型的系统，模糊控制比传统的三冲量控制更容易实现全自动并且控制作用相当有效。

In some designs, the effect of spraying which advances the steam condensation is not all, or not fully, considered. In fact, the increased surplus steam dome volume due to this effect has been taken into consideration as a safety factor in the equipment design.

有些设计在计算中不考虑或不完全考虑喷水促进蒸汽凝结的作用，实质是将这种作用客观上所增加的多余蒸汽容积，作为设备设计的安全裕量。

Other equipment, for instance: Water treatment equipment, oxygen-eliminating device, volume type water heater, dividing the steam dome, etc..

其他设备如：水处理设备，除氧器、容积式水加热器、分汽包等。

The modern industry boilers all develop in the direction of the large capacity high parameter, the general boiler is the larger in capacity, person who holds water of steam dome relative and light, water demand fluctuated to allow less .

现代工业锅炉都向着大容量高参数的方向发展，一般锅炉容量越大，汽包的容水量就相对越小，允许波动的蓄水量就更少。

So Cable dome is appropriate for large span roof structures very much.

因此它非常适宜于大跨度建筑的屋盖设计。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
