自1985年以来，由苏必利尔湖上的浮标测量到的水表温度以每10年增长1.2度的速率上升，比湖面上方的空气升温速率快15%，并且是湖周围陆地升温速率的2倍。
Since 1985, surface water temperatures measured by lake buoys have climbed 1.2 degrees per decade, about 15 percent faster than the air above the lake and twice as fast as warming over nearby land.
结论：地尔硫对人体房室结功能影响具有快频率依赖性特点，这种作用使其在心动过速时选择性抑制房室结。
Conclusion: Diltiazem depresses human atrioventricular nodal function in frequency-dependent manner, these effects lead to highly selective depression of AV nodal function during tachycardias.
