循环流化床锅炉如何进行一、二次风机性能测试？
参考答案：
为了保证锅炉运行时风机调节的准确性，防止出现偏差，循环流化床锅炉在投入运行前必须进行一、二次风机性能测试，为以后提供可靠依据。其操作步骤是开启吸风机、一次和二次风机，调整炉膛负压，分别按25%、50%、75%、100%额定负荷所需风量，调整所测风机入口挡板开度，改变烟风系统阻力，记录风机出口风压、风量及电流，分别绘制出风机运行特性曲线。
You have probably heard it before, most likely from your English teacher. If you want to become a good writer, read good writing. Unluckily, you may not have understood what did good to you and even what you were supposed to get from that experience. As you start reading a book, poem, or story, do so with no thought at all and the experience will improve your writing. you may not have understood what did good to you and even what you were supposed to get from that experience. or to learn. As you progress through the work, think about whether it is “easy” reading or not. Do you become so interested in the subject and flow of the writing that you completely forget the person who wrote it, or does the composition sometimes call too much attention to itself through words and phrases that seem out of place or unexpected? The second situation is a chance to learn from the writer’s mistakes. In fact, the reader should not have to worry about how a writer does “his thing” ... he should be able to just enjoy and learn. Every time a word strikes you as poorly chosen, stop to consider why it has this effect. Also, do not spend a lot of time analyzing (分析) the passage but put more efforts in enjoying it from the whole. Another thing I do, particularly with nonfiction (非小说) books, is to select a part to read as if it is a completely separate work. Once again, read as a common reader rather than a critic (批评家). For learning how words and phrases work together on the most basic level, however, nothing is more suitable than devoting yourself to reading poems. A poet is often trying to put a book’s worth of meaning and feelings into lines, and every side of the work shows a very close attention to craft (工艺). As you can see, there is no simple way of reading to improve your writing. The key is not to make it boring. Select writers you admire or like most, and enjoy their works as anyone else would. As long as you are reading, you are improving yourself as a writer.
