新型缩氨基硫脲席夫碱CuCl2配合物<br /> 催化C-N偶联反应<br />
应用香草醛缩氨基硫脲希夫碱(L1)作为一种新配体与 CuCl2形成配合物成功催化了咪唑类化合物的芳基化反应,重要的是该类配体与 Cu(Ⅱ)配合而形成的催化体系得到了较 Cu(Ⅰ)更好的催化效率。因为,Cu(Ⅱ)的经济性和稳定性都大大优于 Cu(Ⅰ),所以...
Model study on in-situ detection of inclusion in liquid metal by ultrasonic waves
The possibility of using ultrasonic waves to in-situ detect the inclusions in liquid metals is researched by a water model. The effects of inclusions with different properties on ultrasonic waves propagating through wate...
Research on the method of medium-long baseline solution only using Fr(φ)
Because of the lack of cycle slips detection and restoration as well as integer ambiguity determination, dual-frequency observation can not be adopted in the method of baseline solution only using Fr(φ) to correct ionosp...
A fast arc detection method for scanned line-drawing recognition based on discrete curvature
This paper presents a fast arc detection method which is used for scanned line-drawing graphics recognition. It is a kind of method which is from arc supposition to arc verification. Firstly extract the skeleton of the l...
