Experimental results of three-bit latching ferrite phase shifter are provided.

给出了三位锁式铁氧体移相器的实验结果。

The results show that the toughness of over-heated zone increased greatly because of austenite film lying in lathy martensite and a few ferrite.The toughness of fine grained zone decreased due to many factors,such as acicular martensite,a small quantity of austenite film,carbide separation and so on.

结果表明，10Ni8CrMoV这一新型钢种的模拟焊接热影响区的过热区和细晶区表现出与绝大多数材料完全相反的规律，过热区存在少量的铁素体组织，马氏体板条束之间形成了一定量的奥氏体薄膜，这些韧度相的存在使得过热区的冲击韧度与基体相比有了较大的提高；细晶区部位奥氏体含量很少，细小的板条马氏体端部呈针状特征造成应力集中，易于诱发裂纹。

A ferrite effectively even with a significant net DC or low frequency magnetomotive force input.

在输入一显著的净直流电或低频生磁力之下，铁氧磁体能仍可能有效的运作。

And manganic manganous oxide is the main material to produce ferrite.

而四氧化三锰是生产软磁铁氧体的重要原料。
