undulation

what it means

An undulation is one rise and one fall of a smooth, rolling movement — and the word almost always turns up in the plural, because that kind of movement never happens once. Watch a field of wheat when the wind crosses it. The whole surface lifts and drops in slow lines, and nothing is actually travelling except the shape. That is the picture, and it holds everywhere: a snake moves by undulation, so does a ribbon, so does a long piece of cloth held at one end. Then the word leaves the physical world. Land undulates, a voice undulates, a year's sales undulate — anything that goes up and down gently instead of jumping.

Una undulation es una subida y una bajada de un movimiento suave que se repite; por eso casi siempre aparece en plural. Mira un trigal cuando lo cruza el viento: la superficie sube y baja en líneas lentas, y en realidad no viaja nada, solo la forma. Así se mueve una serpiente. Y un terreno o un gráfico también undulate.

Uma undulation é uma subida e uma descida de um movimento suave que se repete; por isso quase sempre aparece no plural. Olhe um trigal quando o vento passa: a superfície sobe e desce em linhas lentas, e nada viaja de verdade, só a forma. É assim que a cobra anda. Um terreno ou um gráfico também undulate.

Une undulation, c'est une montée et une descente d'un mouvement souple qui se répète — d'où le pluriel, presque toujours. Regardez un champ de blé quand le vent le traverse : toute la surface se lève et retombe en lignes lentes, et rien ne se déplace, sauf la forme. C'est ainsi qu'avance un serpent.

Undulation adalah satu naik dan satu turun dari gerak halus yang berulang — karena itu hampir selalu jamak. Lihat ladang gandum saat angin lewat: seluruh permukaan naik dan turun dalam garis lambat, dan tidak ada yang berpindah kecuali bentuknya. Begitulah ular bergerak. Tanah dan grafik pun bisa undulate.

Undulation, yumuşak bir hareketin bir yükselişi ve bir alçalışıdır; bu yüzden neredeyse hep çoğul gelir. Rüzgâr geçerken buğday tarlasına bakın: yüzeyin tamamı yavaş çizgiler hâlinde kalkıp iner, gerçekte yol alan bir şey yoktur — yalnızca biçim. Yılan da böyle ilerler.

undulation は、なめらかな動きの「ひと上がり、ひと下がり」です。一度で終わらないので、たいてい複数形で出てきます。風の渡る麦畑を見てください。表面全体がゆっくりした線になって上下しますが、動いているのは形だけです。蛇もこの動き方をします。土地も売上のグラフも、跳ねずに緩やかに上下すれば undulate します。
