atmospheric propagationとは 意味・読み方・使い方

A sound collecting system collects the sound by using the change of an atmospheric pressure accompanied with sound propagation that changes optical speed in the region.例文帳に追加

音収集システムは、音の伝播に伴う気圧変化がその領域における光の速度を変化させることを利用して音を収集する。 - 特許庁

To provide more accurate simulation of receiving performance of a satellite-ground laser communication, especially while considering a case where a propagation path is blocked due to cloud or the like or changed due to atmospheric fluctuations.例文帳に追加

衛星−地上間光通信の受信特性を、特に伝搬経路が雲等による遮断され、或いは大気のゆらぎにより変化する場合を考慮しつつより正確にシミュレートする。 - 特許庁

A liquid, that is a substance in which an ultrasonic propagation velocity is higher than that in the atmosphere (atmospheric air) inside the pipe 100, is put between a main body 21 of a dimension measuring instrument 20 and the pipe 100, and an inside diameter of the pipe 100 is measured noncontactly by a sensor 29 using an ultrasonic wave.例文帳に追加

寸法測定装置２０の本体２１と配管１００との間に、配管１００内の雰囲気（大気）よりも超音波の伝播速度の高い物質である液体を入れておき、超音波を用いたセンサ２９により非接触で配管１００の内径を計測する。 - 特許庁

To provide a ventilation path opening/closing device capable of smoothly executing the opening/closing operation and reliably preventing propagation of the differential pressure in a ventilation path even when the atmospheric pressure is fluctuated even when the device is used in a place where unexpected differential pressure is generated such as a ventilation path for ventilation of a railroad vehicle which is driven at a high speed.例文帳に追加

高速で運転される鉄道車両の換気用の通風路等、不意の差圧が生じる箇所に用いた場合においても、開閉動作がスムーズで、気圧変動が生じても差圧が通風路を伝播するのを確実に防ぐことのできる通風路開閉装置を提供する。 - 特許庁
