The Study of Application of ZST Microwave Dielectric Ceramics Used to Dielectric Oscillation

ZST微波陶瓷在介质振荡器上的应用研究

The effects of composition of ZST system microwave ceramic on dielectric properties are studied .

研究了ZST系微波陶瓷的组成对介电性能的影响。

The result shows that the diversity of ZST is high but the evenness is low .

结果表明，紫金山风景区以阔叶林景观为主体，且斑块较大而连片，其它景观小而分散，多样性较高但均匀度较低。

ZST-80A型织物折皱弹性仪简介

The ZST & 300 is a SCR inverter arc welding power sou - rce .

ZST&300是可控硅逆变式弧焊电源。

In 2013 , Mr. Seiden received a call from a lawyer representing a large investor in ZST Digital Networks , a Chinese equipment maker .

2013年，塞登接到中国设备制造商神阳科技公司一名大额投资者的代理律师的电话。

The secondary phase of Bi_2Ti_2O_7 were segregated at grain boundaries when the amount of Bi_2O_3 addition was more than 2 % , and the microwave properties of ZST ceramics were decreased .

掺入量大于2%（质量分数）时，ZST系微波陶瓷在晶界偏析形成了Bi2Ti2O7新相，微波性能下降。
