In this dissertation, three series of hydrophilic-hydrophobic IPNs were designed and successfully synthesized via sequential polymerization followed by chemical conversion, the structures were characterized by FTIR and DSC, and the swelling and adsorbing properties of these IPNs were investigated. 本论文采用分步聚合和化学转化法成功的合成了三个系列的亲水/疏水性互穿聚合物网络,利用FT-IR及DSC进行了结构表征,并对其溶胀和吸附性能进行了研究。
The Application of the Programmable Controller in the Sequential Feed Control by Frequency Conversion Speed Regulation 可编程序控制器在变频调速顺序给矿控制中的应用
In the study, at the same time taking into account the sequential substates and concurrent substates, conversion of sub-state through the state of the complex as a small class diagram using the same conversion method can be realized. 在研究中,同时也考虑了顺序子状态和并发子状态的转换情况,通过把复合状态看作一个小的类图而用同样的转换方法即可实现。
The system includes sequential control circuits and digital signal communication circuits with the core of the FPGA, Butterworth low pass filter circuits and analog digital conversion circuits and so on. 该系统主要包括:以FPGA为核心的时序控制电路和数字信号通信电路、巴特沃斯低通滤波电路和模数转换等电路。
