Grain size is small after intermediate annealing. Small and homogeneous grains are obtained after decarburizing annealing.
中间退火后晶粒细小，脱碳退火后晶粒细小均匀。

The intermediate tillers could increase grain number per ear by over 5.44% at the same planting density. This indicates that it has a great potential for increasing yield.
在相同密度条件下，利用中位蘖栽培，能提高每穗粒数5．44％以上，表现出具有较大的增产潜力。

In polycrystalline samples, the intermediate-frequency mechanism is interpreted as the grain-boundary conduction mechanism.
