countercurrentsとは 意味・読み方・使い方

When using the immersion nozzle 2 to perform continuous casting of molten steel while applying a static magnetic field produced by electromagnetic brakes 4, MHD countercurrents, which flow toward the discharging holes 3, ascend toward a surface level 5 through a central flow passage formed between the two dispersion preventing plates 6, so that the MHD countercurrents become hard to come into contact with a solidification interface at the center part.例文帳に追加

この浸漬ノズル２を用い電磁ブレーキ４による静磁場を印加しつつ溶鋼の連続鋳造を行えば、吐出孔３に向かうＭＨＤ対向流は２枚の分散防止板６に挟まれた中央の流路を通じて湯面５に向かって上昇し、センター部の凝固界面との接触が生じにくくなる。 - 特許庁

To provide an immersion nozzle capable of effectively reducing the generation rate of surface defects in the center part of a cast slab, which are caused by MHD countercurrents, and of which the structure is simple and the maintenance is easy, and to provide a continuous casting method using the immersion nozzle.例文帳に追加

ＭＨＤ対向流による鋳片のセンター部の表面欠陥発生率を効果的に減少させることができ、しかも構造が簡単でメンテナンスも容易な浸漬ノズル及びこれを用いた連続鋳造方法を提供する。 - 特許庁

This control is so performed as to let normal and reverse countercurrents flow to each of the armatures of the two DC motors M1 and M2 at the time of operation when torque does not work on the rotary shafts 6 of the two DC motors M1 and M2.例文帳に追加

この制御は、２台の直流電動機Ｍ_____1 ，Ｍ_2 の回転軸６にトルクの働かない運転時に、２台の直流電動機Ｍ_1 ，Ｍ_2の電機子のそれぞれに正逆対向電流を流すようなされる。 - 特許庁
