grain size的音標(biāo)是[?gre?n sa?z]，基本翻譯是“顆粒大小”，速記技巧可以是聯(lián)想記憶：grain“谷粒” → 顆粒大小。

英文單詞“grain size”的詞源可以追溯到拉丁語“granum”和“gratus”，意為“顆粒”或“小顆粒”。這個詞在英語中用來描述物質(zhì)中的顆粒大小。

變化形式：

1. 大小（大小）：直接來自英文單詞“grain size”，表示顆粒的大小。

2. 粒度（granularity）：這個詞在計(jì)算機(jī)科學(xué)和統(tǒng)計(jì)學(xué)中常用，表示數(shù)據(jù)或信息顆粒的大小和詳細(xì)程度。

相關(guān)單詞：

1. “granule” - 顆粒，小顆粒，這個詞在生物學(xué)和化學(xué)中常用，表示小的顆粒或晶體。

2. “size” - 大小，這個詞在英語中非常常見，可以指任何物體的尺寸或大小。

3. “particle” - 粒子，這個詞在物理學(xué)和化學(xué)中常用，表示一個小而獨(dú)立的物體或物質(zhì)部分。

4. “coarse” - 粗糙的，這個詞用來描述顆粒或物質(zhì)的大小或質(zhì)地。

5. “fine” - 精細(xì)的，這個詞用來描述顆粒或物質(zhì)的大小或質(zhì)地，與“grain size”相反。

舉例來說，“grain size”可以用來描述土壤中的顆粒大小，也可以用來描述圖像或數(shù)據(jù)集中的像素大小。這個詞在科學(xué)和工程中非常常見，可以幫助我們理解物質(zhì)或數(shù)據(jù)的基本特征。

常用短語：

1. grain size distribution - 粒度分布

2. grain size analysis - 粒度分析

3. fine grain size - 細(xì)粒度

4. medium grain size - 中粒度

5. coarse grain size - 粗粒度

6. grain size range - 粒度范圍

7. large grain size - 大粒度

雙語例句：

1. The sedimentary rocks we studied had a wide grain size distribution. （我們研究的沉積巖具有廣泛的粒度分布。）

2. The riverbeds in the area have medium grain sizes. （該地區(qū)的河床具有中等大小的顆粒。）

3. The sandstone has a fine grain size and is suitable for building materials. （砂巖具有細(xì)小的顆粒，適合作為建筑材料。）

4. The grain size of the soil varies with the climate and soil type. （土壤的粒度隨氣候和土壤類型而變化。）

5. The grain size of the sand in the beach is large enough to make good building sand. （海灘上的沙子粒度足夠大，可以作為良好的建筑用沙。）

6. The grain size of the rice grains varies depending on the variety of rice plant. （稻谷的粒度根據(jù)水稻品種的不同而變化。）

Grain Size and Its Importance in Nature

Grain size is an important factor in nature that affects many aspects of life, from the way plants grow to the way materials behave. From tiny sand grains to large boulders, nature is full of different sizes of matter that interact with each other and influence their environment.

For plants, smaller grains allow for more surface area to absorb water and nutrients, while larger grains provide stability and support for structures such as trees and buildings. In materials science, grain size can affect the strength, hardness, and other mechanical properties of materials. In geology, grain size can help us understand the origin and evolution of rocks and soils, as well as the environment in which they were formed.

Moreover, grain size can also have an impact on the aesthetic value of materials and landscapes. Fine-grained sands are often used for fine crafts and building materials, while coarse-grained rocks can form beautiful landscapes such as beaches and dunes.

Overall, grain size is an essential aspect of nature that plays a crucial role in many aspects of life, from the microscopic to the macroscopic scale. Understanding grain size and its relationship to other factors such as composition, texture, and environment can help us better understand and appreciate the diversity of life on Earth.
