We have developed a simple and easy-handling procedure for copper-catalyzed cyanation of aryl halides using K4[Fe_6] as the cyanide source. The present procedure has ligand- and base-free advantages, and was accomplished under the conditions of exposure to the air without degassing of the solvent.4. We carried out the selective control of preparation for phenyl ether and phenol from iodobenzene with 10 mol% of Cu_2·H_2O as the catalyst under the condition of exposure to air.

This method can make sure the structure radiant sound status in total noise and the detail phonate part quickly and correctly.(3) Study on the control mechanism of structure noise radiated from rotary machines, we build a common model of rotary machine structure noise analysis relied on the general characters of rotary machines. Based on this model, we analyzed various influence factors to structure radiant noise using the union of revolution and numerical calculation method. We found that the joint stiffness between the rotor and the frame is the most sensitive parameter of structure radiant noise by calculating and analyzing.
根据本文对于旋转机械结构噪声控制技术的研究结果和惯性振动筛工作的特殊要求,对有关参数的选择进行了讨论,并通过试验为降低惯性振动筛噪声找到了两个新的方法:即,在轴间相对运动要求不高的情况下,可以在激振器与筛体之间安装一组减振器,通过适当选取减振器参数,既可以使机体在工作频率附近获得稳定振幅,保证振动筛正常工作,又可以使机体的高频响应减小,降噪效果显著;反之,如果轴间相对运动精度要求(来源:1aABC论文网www.abclunwen.com)较高,可以采用空心滚动体轴承,在保证滚动体强度的条件下也可以获得较好的降噪效果。

PID control has been successfully used in many fields such as aviation, spaceflight, missile and other industry control system. The study object in the thesis is missile that flies hedgehopping over sea at minimum altitude. Many interference problem must be solved when missile flies at minimum altitude, otherwise the missile would be dangerous of bumping into the sea under the circumstances of bad weather and wave. The different kinds of interference factors are contradictions with requirements of control system, which can not be solved by PID control.

According to the change of the kinds of elements content in slag, F in slag volatilizes in the form of KF and NaF, KF volatilizes much more easily than NaF, KF plays a leading role in the F volatilization, theoretical analysis shows that the saturation vapour pressure of KF in the test slag is 31. 4 times of NaF; when F content is far more than K, KF volatilization is first order grade reaction, it is dominated by K content, the apparent activate energy is 275. 30KJ/mol.
