core sample：核心樣本

音標(biāo)：/?k??rs ?sɑ?mp/

基本翻譯：核心樣本是一種從地層或物體中取出的小塊樣本，用于地質(zhì)學(xué)家的研究和分析。

速記技巧：記住“core”這個(gè)單詞，它還有“核心”的意思，再加上“sample”這個(gè)單詞，表示“樣本”，組合起來(lái)就是“核心樣本”。

使用場(chǎng)景：在地質(zhì)學(xué)、考古學(xué)、環(huán)境科學(xué)等領(lǐng)域中，核心樣本是一種非常重要的研究工具。

Core Sample:

詞源：來(lái)自拉丁語(yǔ)“core”意為“核心”，加上“sample”意為“樣本”。

變化形式：在英語(yǔ)中，核心樣本的復(fù)數(shù)形式是coresamples。

相關(guān)單詞：

1. Core Drilling：核心鉆探，指在地質(zhì)學(xué)中用于采集地下樣本的過(guò)程。

2. Sampling Error：抽樣誤差，是指在樣本數(shù)據(jù)中可能存在的偏差，與總體大小和樣本選擇有關(guān)。

3. Subsample：子樣本，是指在更大樣本中抽取的一部分?jǐn)?shù)據(jù)，用于分析或測(cè)試。

4. Sample Size：樣本大小，是指用于統(tǒng)計(jì)檢驗(yàn)的樣本數(shù)量，決定了抽樣誤差和置信區(qū)間的大小。

5. Bias：偏倚，是指在樣本數(shù)據(jù)中存在的偏差，可能與總體特征有關(guān)。

6. Random Sampling：隨機(jī)抽樣，是指從總體中隨機(jī)抽取樣本的過(guò)程，旨在減少抽樣誤差。

7. Representative Sample：代表性樣本，是指能夠代表總體的樣本，通常用于評(píng)估總體的特征或趨勢(shì)。

8. Non-Response Bias：非回應(yīng)偏差，是指在抽樣過(guò)程中出現(xiàn)的回應(yīng)率差異，可能影響樣本的代表性。

9. Substitution Sampling：替代抽樣，是指用其他方法代替?zhèn)鹘y(tǒng)抽樣過(guò)程的方法，例如使用大數(shù)據(jù)或機(jī)器學(xué)習(xí)技術(shù)。

10. Sampling Frame：抽樣框架，是指用于確定樣本總體結(jié)構(gòu)的數(shù)據(jù)框架，通常包括人口統(tǒng)計(jì)和地理信息等。

以上這些詞匯都與核心樣本相關(guān)，反映了其在科學(xué)研究和社會(huì)調(diào)查中的重要性和廣泛應(yīng)用。

Title: The Importance of Groundwater Sampling

Groundwater is a crucial resource for many ecosystems and human communities, providing clean water for drinking, agriculture, and industry. However, groundwater levels and quality can be affected by various factors, including pollution, climate change, and human activities. To ensure the sustainability of groundwater resources, it is essential to conduct regular groundwater sampling to monitor water quality and quantity. Through sampling, we can identify any changes in water quality or quantity that may indicate a potential problem and take appropriate action to address it. Additionally, groundwater sampling can provide valuable information for planning future water management strategies and ensuring sustainable water use in our communities.
