摘要：针对转炉钢包机构上水口子母台周围易产生裂纹、上滑板易产生横断、下水口与长水口配合不佳等问题,优化上水口子母口的结构,增加子母台的有效果使用面积,提高上水口与上滑板配合安全系数,在与长水口配合角度不变的情况下,延长配合深度,将装配下水口调整为内装式,从设计上改进了滑板耐材安全系数,减轻了职工劳动强度,缩短了修包时间。

摘要：平均官能度是影响醇酸树脂配方设计的重要参数 .丙烯酸预聚物改性醇酸树脂的配方中 ,只有丙烯酸预聚物的官能度是未知参数 .通过IR光谱、GPC分析以及化学滴定法能估算出预聚物的官能度 .利用测定的官能度对醇酸树脂涂料进行配方设计 ,可以提高设计的可靠性 .

摘要：The SSRF (Shanghai Synchrotron Radiation Facility) home-made digital power supply controller adopts advanced DSP and FPGA as core and precision ADC as data acquisition *** controller which is inlaid in the power supply case is composed of two cards of ADC and *** controller can communicate with IOC by optical fiber through the UART *** controller can easily change the parameter of the power supply to achieve high stability and *** a replacement of the imported PSI controller,the controller is mainly used in the SSRF media power supply (stability less than 100ppm),and can match all of the specifications.
