The remanence, coercivity and maximum energy product decrease with deteriorated grain alignment.

Metal magnetic powder with fine particles and relative higher coercivity and remanence are ideal materials for high density magnetic recording.

In the steel tube nondestructive inspection by using magnetic technique,the steel tube needs to be magnetized,thus the magnetized steel tube has remanence.

It is pointed out that the vibration with main frequency of 50 Hz is greater only in part of this transformer on load, and the switching surge current has maximum value of same kind of transformer, which have the possibility of obvious residual magnetism in this transformer.

The closing excitation inrush current was large because the residual magnetism of the transformer was overly large.

Checking and analysis revealed at last, that it was caused by residual magnetism after repair, the polarity of which was opposite to that effected by direct current in the rofor.

On the Reasons of Macroeconomy Total Output Surplus;

Recent years has seen periodic surplus of refining capacity in Asian Pacific region.

In this article,Bruno production function is selected for the two step analysis of the Chinese agricultural output,which has taken the country s surplus labour force and its transfer into full consideration.

There is no doubt that Chinese economy has to face a fact------excess liquidity now.

After that, Japan take measures to encourage foreign investment and make yen internationalized which, to some extent, ease the situation of excess liquidity.
