The optimal operation condition of Friedel-Crafts acylation for product Ⅰ was determined by orthogonal experiment: 0.02mol N-ethyl- carbazol, n Benzoyl chloride/n N-ethyl- carbazol=1.2, n AlCl3/n N-ethyl- carbazol=1.2 , at 25 oC for 3.5h. The yield was 94.6%.

通过正交设计实验，探讨了产物Ⅰ的Friedel-Crafts 酰化的最佳反应条件：N-乙基咔唑为0.02mol时，反应物苯甲酰氯与N-乙基咔唑摩尔配比为1.2。，催化剂AlCl3与N-乙基咔唑摩尔配比为1.2， 25℃下反应3.5h，产率可达94.6%。

Reaction of L-tyrosine with benzyl bromide in the presence of copper sulfate led to the protection of phenol group on the side chain of L-tyrosine to give H-Tyr-OH in 45% yield via a copper complex intermediate.

酪氨酸与溴化苄在硫酸铜存在下反应，选择性地在其侧链酚羟基上引入苄基保护基，通过反应条件的优化，反应产率达到45%。

I remember when I was born my daughter's doctor told me that I fetal position is not correct, it is necessary to open, when I am well aware that section, then if the baby might not奶吃also very detrimental to their own, so I decided to shun the middle, into the delivery room did not expect less than half an hour on the birth , and all are smooth, when I came to realize that the most important strength and confidence...

记得我生我女儿时医生说我胎位不正，要剖腹，当时我很明白如果剖腹的话宝宝可能没奶吃也对自己很不利，所以我下定决心顺产，没想到进产房不到半小时就生下了，而且一切都都有顺利，这时我才明白坚强和信心最重要。。。

Summary: Hainan seeking sea iron wood bracelet related presentations, Hainan under the locals know that, thank you!

求海南产的海铁木手链相关介绍，有海南本地人知道的说下，谢谢！

Study on the effects of the pressure, temperature and time on the extraction rate of the essence oil from the cinnamon by supercritical CO2 extraction.

研究了超临界CO2萃取肉桂精油时压力、温度、萃取时间等因素对提取效果的影响，通过正交实验确定最佳的萃取工艺条件为：萃取压力15MPa，温度40℃，时间2h，此条件下肉桂精油的产率为3.69%。

Generally speaking, as long as you are a good measure of the total width of the window and the job can calculate the required amount of cloth, but if the measure on its own, then have to pay attention to some details, such as the window of a high degree of measurement from the start Chuang Lianhe To outweigh the lower edge of the window will not be emptied of its width is also probably have to pay more on the side of 5-10 cm, but if they are Banyao have to pay attention to whether there is a window sills, to be done within the window frame, then have to carefully Measure may not yield more than half a centimeter card does not go in and a half centimeters or less emptied of the situation, the track can be installed on the wall or ceiling should also note that some tracks can be linked to the ceiling can also be linked to the walls, some not I suggest you bring home a good-size windows notes, the regional states, take good pictures of each window to the stores, they will suggest you how to use the track and practice

一般来说只要您丈量好窗户的总宽和总高就可以计算所需的布量，但如果自行丈量的话有些细节得注意，比如说窗的高度得从窗帘盒内开始丈量到盖过窗的下缘才不会走光，宽度也是，大概一边都得多加个5-10公分，但如果是半腰窗就得注意是否有窗台，要做在窗框内的话就得仔细丈量不然有可能产多了半公分卡不进去或是少了半公分走光的状况，轨道可以安装的墙面或是天花板也要注意，有些轨道是可以挂天花板也可以挂墙壁的，有些不行，建议你把家里的窗户尺寸做好一份笔记，写明区域，拍好每一窗的照片给店家看，他们会建议您用怎样的轨道和做法
