propagation
의미: The process by which something spreads, multiplies, or is transmitted from one place or organism to another. In horticulture, the breeding or reproduction of plants.
Propagation spans several fields with distinct but related senses. In physics, wave propagation describes how sound, light, or radio waves travel through a medium. In computing, error propagation and signal propagation are standard technical concepts. In horticulture, propagation refers to the various methods — cuttings, grafting, seed — by which plants are multiplied. In social contexts, the propagation of ideas or beliefs carries more neutral connotations than 'propaganda,' though both share the same root. The word always implies transmission across space or through a population.
예문
- The speed of sound depends on the medium of propagation, travelling faster through water than through air. 声速取决于传播介质,声波在水中的传播速度比在空气中更快。La velocidad del sonido depende del medio de propagación, desplazándose más rápido a través del agua que del aire.音の速度は伝播媒質に依存し、空気中よりも水中の方が速く伝わる。음속은 전파 매질에 따라 달라지며, 공기보다 물을 통해 더 빠르게 전달된다.
- The nursery specialises in the propagation of rare native species, including several that are critically endangered. 该苗圃专门从事珍稀本土物种的繁殖,其中包括几种极度濒危的物种。El vivero se especializa en la propagación de especies autóctonas raras, incluidas varias en peligro crítico de extinción.その苗圃は希少な在来種の繁殖を専門としており、絶滅が危惧される数種も含まれている。그 묘목장은 멸종 위기에 처한 여러 종을 포함하여 희귀 자생종의 번식을 전문으로 한다.
- Neural networks learn through a process called back-propagation, in which errors are transmitted backwards through the network to adjust its parameters. 神经网络通过一种称为反向传播的过程进行学习,其中误差被反向传递通过网络以调整其参数。Las redes neuronales aprenden mediante un proceso llamado retropropagación (back-propagation), en el que los errores se transmiten hacia atrás a través de la red para ajustar sus parámetros.ニューラルネットワークは逆伝播(バックプロパゲーション)と呼ばれる過程を通じて学習し、誤差をネットワーク内で逆方向に伝えてパラメータを調整する。신경망은 역전파(backpropagation)라 불리는 과정을 통해 학습하며, 오차를 네트워크 내에서 역방향으로 전달하여 매개변수를 조정한다.
