harmonic mean diameterとは 意味・読み方・使い方

The increase in the harmonic mean grain diameter is performed by decreasing the using ratio of the small grain sintered ore having not larger than a prescribed grain diameter.例文帳に追加

調和平均粒径の増加は、所定粒径以下の小粒焼結鉱の使用割合を減少することにより行う。 - 特許庁

A relation among the RDI of the sintered ore, harmonic mean grain diameter and the ventilation in the blast furnace, is obtained and the ventilation in the blast furnace is kept well by increasing the harmonic mean grain diameter so as to secure the ventilation in the blast furnace according to the increase in the RDI.例文帳に追加

焼結鉱のＲＤＩと調和平均粒径及び高炉内通気性との関係を求め、ＲＤＩの増加に応じて高炉内の通気性を確保できるように調和平均粒径を増加して高炉内の通気性を良好に維持する。 - 特許庁

The granulated product of the waste plastic to be blown into the rotary kiln has an average index δ of a strength of ≥49 and preferably has a harmonic mean diameter of the granulated product immediately before being blown into the rotary kiln of ≥2 mm.例文帳に追加

ロータリーキルン内に吹き込む廃プラスチックの造粒物の平均強度指数δが４９以上であり、かつ吹き込む直前の前記造粒物の調和平均径が２ｍｍ以上であることが好ましい。 - 特許庁
