液化气分析,FID程升中温时基线不稳? 回复 2# zyp0009928 谢谢老师指教,我们用的柱子是进口毛细管柱,升温速率是5终温180,基线不稳是170度左右基线就不是直线,而是高低不平,象连绵的小山,还不是峰,主要组分都出完了,密密麻麻全是杂峰,降温后基线就好了,是不是象您说的柱子快坏了呢?(液化气分析)查看更多

好的英语是“读”出来的? 改变人生的100个方法(8) 71. look inside. most of us wait to discover who we are from the impressions we get from other people. "oh do you think i'm like that..." if we get positive feedback, that's great. it helps build us up. but ideally, your journey should be internal. travel deeper and deeper inside to find out your own potential. your potential is your true identity. it only waits for self motivation to come alive. 72. go to war. * research shows during times for war suicide rates go down. we don't to wait for something tragic. we don't have wait until we go to war to attack us from without. we can get the same vitality by challenging ourselves from within. "all battles are first won or lost in the mind." joan of ark. ask yourself what would you do if you had only one year to live. how would i live differently? what exactly would i do? this exercise can reveal skills inside of you that your not using today. 73. make small change. when practicing self motivation, it can be common that you get a lot of different type of mood swings. sometimes you'll be on a real high on the idea of who you can be and set up to change yourself overnight. then your old habits will pull you back to who you use to be and then you become demoralized. you have eventually accept the idea that great things are created slowly. great painting, great building. so why can't you see that great people are also created slowly. so if you willing to see yourself as a masterpiece in progress, then you'll love small changes. you'll be excited by a tiny thing you did differently today. you should celebrate because your moving in the direction of self creation. 74. do something badly. **** sometimes we don't do things because we not sure we cannot do them well. we feel that we are not "in the mood" or our energy levels is not are the right state to do that task that we have. so we put it off or wait for inspiration to arrive. we're so afraid to do things until we're sure we can do them well, we end up not doing anything. this is the source of all writers block btw. "if a thing is worth doing, it's worth doing badly." if your not motivated to do something you know you need to do, just decide to do it badly. add a little self deprecated humor. be comedic about what your doing. and then enjoy what happens to you once your in the process. 75. be a visioneer. the principle of "visioneering." you cannot do anything you cannot picture yourself doing. visioneering is just another word for picturing yourself. once you make the picturing process conscious and deliberate, you begin to create the self you want to be. 76. shine your light. **** taking things lightly was the most spiritually advanced thing you can do to improve your effectiveness in life. after all, it's god's angels that take themselves so lightly that they are able to fly. and if his angels takes themselves so lightly, imagine how lightly he takes himself. your own motivational level will always be lifted with humor. anytime your stuck, ask yourself to take things lightly. ask yourself to look for some funny solutions. laughter will destroy all limits to your thinking. when your laughing, your open to anything. 77. be a list writer. **** never hesitate to site down and make lists. the more you write down what it is that you want, the more you can dictate your future. a goal gains power when you write it down and it gains more power every time you write it down. now we're always looking for motivation in what others have written. but if you become a creative list maker, you'll learn how to motivate yourself by what you've written. 78. be the change. **** don't try to change other people. it doesn't work. you'll waste your life trying. we talk to our children for hours in what we think they should do with their life. but children don't change from what we say, they learn from what we do. by being what you want them to be, you can lead by inspiration. what you tell people to do often goes right by them. who you are, doesn't. the change in you is contagious. when you yourself change, watch how the people around you change. 79. see the gold. **** in every circumstance, we can look for the gold or we can look for the filth. and what we look for, we'll find. opportunities are only available to a careful observer. your opportunities will multiple when and only when you choose to see them.查看更多

请教泵的单双端面机械密封的选择根据? 这个选型是没有一个特殊的标准,主要还是根据你的介质特性等参数来选择,还有就是节省费用方面和寿命的考虑,选单封的工位,一般都可以改成双封,可是价格就高了很多。双封应用的场合一般是介质有毒和危险介质的时候。查看更多
板换和列管式换热器的使用区别? 楼上对板换的理解很是深刻啊,看下我们代理的荷兰apex的板式空气预热器。 其独有的柱塞型流体形态和专利的气幕设计技术可以有效的防止腐蚀,大大延长了设备使用寿命。全焊接的结构由于采用了考登钢,其换热板厚度仅为1.5mm左右,具有较高的换热效率。 整套设备分低温段和高温段双程设计,低温段具有较宽的通道间隙可以减低流体流速,降低换热效率以防止冷端腐蚀,高温段具有较小的通道间隙可以获得较高的换热效率。 [ ]查看更多
