求翻译：如果1是什么意思？

If a < 2 , the node is considered ideal for PV node .

If 1 <2, is of the opinion that the node is the ideal PV node. The threshold value can be through theoretical analysis, for example, when a = 0.02, the voltage fluctuations on the system relatively comprehensive dynamic equivalent resistance or reactance calculation error is only 2 per cent.

If 1<2, thought this node is the ideal PV node.其中阈值可以通过理论分析得到，例如，当取=0.02时，电压波动对系统相对综合动态等值电阻或电抗计算误差的影响仅为为2%。

If 1<2, the node is considered ideal for PV nodes. Threshold values can be obtained by theoretical analysis, for example, when you take =0.02, voltage fluctuation on comprehensive dynamic equivalent resistance or reactance calculation system error only for 2%.
