基本范例  (2)

测试一个对象是否为有效的事件序列：

Wolfram Language code: EventSeries[{"sell", "buy", "sell"}, {{DateObject[{2025, 1, 9}, "Day"], DateObject[{2025, 10, 6}, "Day"], DateObject[{2025, 12, 23}, "Day"]}}]
Wolfram Language code: EventSeriesQ[%]

测试这个日出事件序列是否有效：

Wolfram Language code: Sunrise[DateRange[Today, Today + Quantity[7, "Days"]]]
Wolfram Language code: EventSeriesQ[%]

范围  (1)

计算连续 100 年的三月春分点时刻：

Wolfram Language code: FindAstroEvent["MarchEquinox", DateRange[DateObject@{2001}, {2100}, "Year"]]
Wolfram Language code: EventSeriesQ[%]

属性和关系  (2)

空 EventSeries 对象是有效的：

Wolfram Language code: EventSeries[{}]
Wolfram Language code: EventSeriesQ[%]

有效的 TimeSeries 对象不是有效的事件序列：

Wolfram Language code: ts = TimeSeries[{30, 42, 50}, {1}]
Wolfram Language code: TimeSeriesQ[ts]
Wolfram Language code: EventSeriesQ[ts]
