求翻译：图1中，为计算备用容量和备用电量被调度的概率和切负荷概率，从0点开始到+∞，按△P为步长等分，由于是正态分布，衰减很快，只要到一较大值截至就可以保证较好的精度。是什么意思？

Figure 1 for the calculation of the probability and the probability of load shedding reserve capacity and reserve capacity is scheduled from 0:00 to + ∞, △ p step decile, normal distribution, decay very quickly, just go to a more large value as of the can to ensure better accuracy.

In Figure 1, for the purposes of calculating reserve capacity and a spare battery is scheduling the probability and probability, all loads from 0 to +∞, and press & # 9655 ;P sub for the step length, because it is a normal distribution, the attenuation is very fast, as long as a larger value as

In Figure 1, the probability which dispatches and cuts for the computation reserve capacity and the spare electric quantity the load probability, from 0 starts to +∞, according to △P is the length of stride division, because is the normal distribution, weakens very quickly, so long as up to may guar

In Figure 1, for calculating capacity and standby power is scheduling probability and probability of load-shedding, starting at 0 o'clock to + ∞, for steps such as p, as is the normal distribution, decay quickly, as long as the larger value as you can to ensure better accuracy.
