Research and Weaving of 田 Shape 3-D Woven Fabric;
田字形立体机织物的研究及织造
On the basis of the principle of variation parameter oscillation, this paper introducesthe research in and making of the 25Hz ferromagnetic frequency demultipliert by using the mixedtesseral iron core, Its dominant feature is the low temperature rise, about 10℃ - 30℃, and its50Hz harmonic separation is less than 25%.
本文根据变参数振荡的原理，介绍了采用混合田字型铁芯的方式，研究制作25Hz铁磁分频器的方法。
