When choosing a value for R6, ensure that Q2's base-emitter voltage is less than approximately 0.5V at the maximum permissible value of the load current.

选择R6的阻值时要确保在负载电流的最高允许值的条件下，Q2的基极-发射极电压大约低于0.5V。

In the event of an overload when ILOAD exceeds its maximum permissible value, the increase in voltage across R6 results in sufficient base-emitter voltage to turn on Q2.

当iload超过最大允许值时发生过载情况，R6上的电压增大导致基极-发射极电压足够大到导通Q2。

In cases where an intended procurement specifies the need for option clauses, the basis for valuation shall be the total value of the maximum permissible procurement, inclusive of optional purchases.

如果意向采购需要规定选择性采购条款，那么此类合同的估价基础应是最大限度允许采购的总值，包括期权购买。
