The second class absorption heat pump can get hot water or vapour using heat potentialdifferenceof middle temperature exhaust gas and lower temperature sink.
第二类热泵可利用中间温度的废热与低温热源之间的热势差，制取热量少但温度高于中温废热的热水或蒸汽。

Results: the taurine could significantly reduced gastric mucosal injury, inhibited the ET release, increase blood flow and potentialdifferenceof gastric mucosa.
结果：牛磺酸可明显减轻胃粘膜损伤，抑制内皮素释放，增加胃粘膜血流量，提高电位差。
