parameter
Meaning: A measurable factor or variable that defines a system or sets the limits within which something operates; in mathematics, a quantity that influences the output of a function.
Parameters are used across many disciplines. In science, they are the variables or conditions of an experiment. In computing, they are values passed to a function. In business and policy, 'parameters' often means the limits or boundaries within which a decision or activity must operate. The word is sometimes confused with 'perimeter' (the outer boundary of an area). Common collocations include 'key parameter,' 'within the parameters of,' and 'set the parameters.'
Examples
- The researchers adjusted several parameters in the model to improve the accuracy of the predictions. 研究人员调整了模型中的几个参数,以提高预测的准确性。Los investigadores ajustaron varios parámetros del modelo para mejorar la precisión de las predicciones.研究者たちは予測精度を向上させるため、モデル内のいくつかのパラメータを調整した。연구자들은 예측의 정확도를 높이기 위해 모델의 여러 매개변수를 조정했다.
- The project must be completed within the parameters set by the budget and timeline. 该项目必须在预算和时间表设定的参数范围内完成。El proyecto debe completarse dentro de los parámetros establecidos por el presupuesto y el calendario.そのプロジェクトは予算とスケジュールで設定されたパラメータの範囲内で完了しなければならない。그 프로젝트는 예산과 일정으로 설정된 매개변수 범위 내에서 완료되어야 한다.
- Water temperature is a critical parameter in determining the rate of the chemical reaction. 水温是决定化学反应速率的关键参数。La temperatura del agua es un parámetro crítico para determinar la velocidad de la reacción química.水温は、化学反応の速度を決定する上で重要なパラメータである。수온은 화학 반응의 속도를 결정하는 데 있어 핵심적인 매개변수이다.
