粉末产物 meaning in Chinese

powdered product

Zny , ni ( 1 - y ) fe2o4 and cobalt substituted ni - zn soft ferrite powders of zn0 . 4ni ( 0 . 6 - a ) coa fe2o4 are synthesized by shs . the shs powders and cycle samples are annealing in 1100 for 2h . their magnetic , and micro structural properties are studied using xrd , vsm and sem techniques . the studies reveal that the value of hc mr and ms of the powder of zn yni ( 1 - y ) fe2o4 are maximal when the value of y is 0 . 4
研究发现：随着zno含量( y值)的增加，粉末产物的矫顽力( hc ) 、饱和磁矩( ms )以及剩余磁矩( mr )先增大(在y = 0 . 4时取得最大值)然后再下降；磁环表面颗粒逐渐长大，孔隙率减少，密度增加；磁环的bs与br先增大再减小，在y = 0 . 4时达到最大；磁环的矫顽力hc是递减的。
