Reliable modeling of the atmospheres of cool white dwarfs is crucial for understanding the atmospheric evolution of these stars and for accurate white dwarfs cosmochronology. Over the last decade {\it...
WDS-A微扫测井测斜系统电路设计
微电扫描测斜 接口电路 逻辑控制 帧计数器
2009/5/19
为了完成测斜系统传感器信号调制、控制、三总线信号驱动、转换及上传数据解调电路功能，根据三总线信号特点，设计出一套数据接口、信号采集与控制电路，帧形成及字形成电路.经过室内及十余次野外油田试验，表明：接口及信号调制控制传输电路达到功能设计要求，微电扫测斜系统电子仪传输后转换精度达到4.2‰，表示每帧数据传输时间的时间字偏差不超过0.3‰，说明该短节电路设计可靠稳定，满足功能要求。

In 1829 Struve discovered a double star denoted as STF 2375 AB
later on. Its separation was 2 . 2. It was noticed by Finsen from the Southern Observatory
(Johannesburg) in 1953 that the component...
