NVTとは 意味・読み方・使い方

A gradual change value Nvt of the target value Tvt is calculated (S108), and when a difference Δ Nvt (=|Tvt-Nvt|) between the gradual change value Nvt and the target value Tvt is smaller than a predetermined value α (step S110:YES), the determination of no anomaly in the control system is prohibited.例文帳に追加

目標値Ｔｖｔの徐変値Ｎｖｔを算出するとともに（Ｓ１０８）、徐変値Ｎｖｔと目標値Ｔｖｔとの差ΔＮｖｔ（＝｜Ｔｖｔ−Ｎｖｔ｜）が所定値αよりも小さいときに（ステップＳ１１０：ＹＥＳ）、上記制御系の異常なしとの判定を禁止する。 - 特許庁

A connection member 19 at the airtight seal section 18 is composed of insulating ceramics where the amount of swirling is equal to or less than 1.5% in 10^21 nvt equivalent of the amount of dosage of neutron, an electric insulation breakdown voltage of 10 kV or higher, and a thermal conductivity of 15 W/mK or higher.例文帳に追加

気密シール部18の接続部材19はスウェリング量が中性子照射量10^21nvt相当量において1.5％以下、電気絶縁耐圧10kV以上、熱伝導率が15W/mK以上の絶縁性セラミックスとする。 - 特許庁
