产生谐波的根本原因是电力系统中器件、设备的非线性，即使供给这些器件、设备的电源是理想的正弦波形电压，电网供给它们的电流也是非正弦波形，即产生了谐波电流，当谐波电流流过线路后，产生谐波压降，使电网电压失真。

So it needs improving or alternating urgently. Some good germplasms for rootstocks for citrus have been picked out and introdcted into. Some somatic hybrids used as rootstocks have been selected through somatoplasm fusion. Some methods in early identification on stability of inherence and copatiblity and dwarf are explored, and they need improving. Rootstocks having some virtues have been selected, but they cannot take the leading place of trifoliate orange. The research method that the rootstocks are only compared with each other should be altered into that the rootstocks and given control measures or environmental conductions are connected to make the rootstocks compared with each other.

在砧木选择研究进展上，中国调查出和引进了一些优良的柑橘砧木种质资源，通过体细胞融合选育出一些可作为柑橘砧木的柑橘体细胞杂种资源；在柑橘砧木资源的遗传稳定性、嫁接亲和性和矮化性等早期鉴定上，探索出一些有待完善的鉴定方法；在砧木选择上，选出一些具有某些优点的砧木，但尚不能冲击枳砧的主导地位，并且选择研究方法有必要把现行单纯的砧木比较改为与砧木种类、栽培技术或环境条件相结合进行比较。
