It was no coincidence that the announcements of the two findings — distant quasars and normal galaxies — were made together at a meeting of the American Astronomical Society (AAS) Jan. 9.

在1月9日，美国天文学会的一次会议上，两个发现——关于遥远的类星体和常规的星系——被同时公布，这并不是巧合。

A new interface was designed for connecting a model 8031 chip microprocessor with H_508 atomic absorption spectrometer and the computer control of the AAS instrument was realized with very low cost.

用自行设计的接口电路将8031单片机与H＿508原子吸收分光光度计连接，以很低的成本使仪器计算机化，灵敏度提高且效果良好。

The rear of the device has a power input, for those times when you don't want to burn through AAs and the bottom has a battery door (thankfully not protected by a screw).
