时间序列上下文中“信封”的含义
Meaning of `envelope` in context of time series
在检查 TIMESAT 时，更具体地说

然后我读到：
"The fits are affected by a number of options for detecting spikes, adapting to the upper envelope..."
信封是什么意思？
In physics and engineering, the envelope of an oscillating signal is a
smooth curve outlining its extremes. The envelope thus generalizes
the concept of a constant amplitude. The
envelope function may be a function of time, space, angle, or indeed
of any variable.
