apertures的音標為[??p??t??(r)]，基本翻譯為“孔；孔洞；開啟；開口”，速記技巧為“ap-er-tures”表示“開孔”。

Aperture這個詞的詞源可以追溯到拉丁語apertura，意為“開口，洞”。它的變化形式包括aperture（名詞，表示孔洞，開口），apertural（形容詞，表示與孔洞或開口有關的），以及apertively（副詞，表示在孔洞或開口處）。

相關單詞包括：

1. aperture（孔徑）：指物體表面上開口或孔洞的大小。

2. iris aperture（光圈）：在攝影中，光圈是鏡頭上可控制的孔徑，用來控制光線量。

3. slit aperture（狹縫光圈）：在光學中，狹縫光圈是指像狹縫一樣的光線路徑，通常用于控制光的強度和方向。

4. ocular aperture（眼睛孔徑）：在生物學中，眼睛的孔徑可以影響視覺效果。

5. aperture angle（孔角）：在光學中，孔角是描述光線通過小孔或狹縫時的角度。

這些相關單詞都與aperture這個詞有著密切的聯系，并且可以用來描述各種與開口或孔洞有關的現象和概念。

常用短語：

1. large aperture 大口徑

2. small aperture 小口徑

3. focal length aperture 焦距光圈

4. iris aperture 瞳孔光圈

5. adjustable aperture 可調光圈

6. fixed aperture 固定光圈

7. wide-open aperture 全開光圈

雙語例句：

Title: The Magic of Aperture

Aperture is an essential component of photography and other optical devices, determining how much light enters the lens and how much is captured by the sensor. A large aperture allows more light to enter, resulting in a brighter and clearer image, while a small aperture can result in blurred images in low light conditions.

In photography, the choice of aperture also affects depth of field, with a larger aperture resulting in a shallower depth of field, which can be used to emphasize the subject and blur the background. Conversely, a smaller aperture results in a greater depth of field, allowing more elements in the background to be captured clearly.

Adjustable aperture allows for precise control over exposure, making it possible to capture images in various lighting conditions with ease. Fixed apertures, on the other hand, are less versatile and may limit the photographer"s creativity when trying to capture a wide range of scenes effectively.

In conclusion, aperture plays a crucial role in optical devices and photography, determining how much light enters the lens, how much is captured by the sensor, and how much depth of field is captured by the camera. Understanding aperture and its effects is essential for creating beautiful and effective images.
