hysteresis

名詞

可算名詞 不可算名詞

A property of a system such that an output value is not a strict function of the corresponding input, but also incorporates some lag, delay, or history dependence, and in particular when the response for a decrease in the input variable is different from the response for an increase. For example, a thermostat with a nominal setpoint of 75° might switch the controlled heat source on when the temperature drops below 74°, and off when it rises above 76°.

日本語の意味

システムの出力が現在の入力だけでなく、過去の状態（履歴）にも依存し、その結果、入力が増加する時と減少する時で出力の応答が異なる現象。 / 入力と出力の関係が単一の明確な関数関係にとどまらず、システムの過去の変化や遅延（ラグ）などの履歴効果が影響する性質。

The thermostat's hysteresis caused the heater to turn on only when the room fell below 74°F and to switch off only after it rose above 76°F, creating a small but persistent temperature oscillation around the setpoint.

サーモスタットの履歴依存性により、室温が74°Fを下回ったときに暖房が入り、76°Fを上回るまで切れなかったため、設定温度の周りで小さく持続的な温度の振動が生じた。

意味（1）

A property of a system such that an output value is not a strict function of the corresponding input, but also incorporates some lag, delay, or history dependence, and in particular when the response for a decrease in the input variable is different from the response for an increase. For example, a thermostat with a nominal setpoint of 75° might switch the controlled heat source on when the temperature drops below 74°, and off when it rises above 76°.

意味（2）

Magnetic friction in dynamos, by which every reversal of magnetism in the iron causes dissipation of energy.
