介绍新需要系数法，把常用的需要系数法和利用系数法统一到一个计算公式中；利用原需要系数法的方便和习惯，引入修正系数α后实质上变成了利用系数法，既避免了求有效台数的繁琐，又克服了凭经验选择KΣP的不确定性；利用α值表和Kx、 cosφ、 tanφ表，可以方便地求出干线、变电所、配电所至各级配电点的负荷，整个计算一次完成。
介紹新需要繫數法，把常用的需要繫數法和利用繫數法統一到一箇計算公式中；利用原需要繫數法的方便和習慣，引入脩正繫數α後實質上變成瞭利用繫數法，既避免瞭求有效檯數的繁瑣，又剋服瞭憑經驗選擇KΣP的不確定性；利用α值錶和Kx、 cosφ、 tanφ錶，可以方便地求齣榦線、變電所、配電所至各級配電點的負荷，整箇計算一次完成。
개소신수요계수법，파상용적수요계수법화이용계수법통일도일개계산공식중；이용원수요계수법적방편화습관，인입수정계수α후실질상변성료이용계수법，기피면료구유효태수적번쇄，우극복료빙경험선택KΣP적불학정성；이용α치표화Kx、 cosφ、 tanφ표，가이방편지구출간선、변전소、배전소지각급배전점적부하，정개계산일차완성。
In tro duces a new demand coefficient method, and integrates the general demand coefficient method and the utilization factor method into one formula; in consideration of the convenience and convention of the former demand coefficient method, the former method is converted to the utilization factor method in essence with the introduction of correction coefficientα, simplifying the procedures for determining the active value of the devices, and avoiding the uncertainty in empirical selection of KΣ P; the load, including that of the main line, transformer station, distribution substation and all sub-substations can be easily determined at a time by use of the tables of αvalues, Kx, cosφ and tanφ.
