“frozen soil”是“凍土”的英文表達，指溫度在0℃或以下且含有冰的土壤或岩石層。以下是詳細解釋：
凍土是指溫度長期或季節性低于0℃、并含有冰的土壤或岩石。其形成與氣候、地質條件密切相關，需滿足散熱大于吸熱的條件才能維持凍結狀态。
根據凍結持續時間可分為三類：
全球約50%的陸地面積受凍土影響，其中多年凍土主要分布于北極圈、西伯利亞、青藏高原等寒冷地區。
如需更完整的凍土工程影響或具體案例，可參考地理學或岩土工程專業文獻。
凍土（frozen soil）指受凍而變得堅硬的土地。它是一種特殊的地表覆蓋，主要分布在高寒地區，包括北極、南極、高山及寒帶地區等。凍土通常由凍結土壤和岩石組成。凍土常見于寒帶高山和高緯度地區，也稱為“永久凍土”。
凍土可以用作名詞或形容詞。作為名詞時，它指的是受凍而變得堅硬的土地，如在例句中所示。作為形容詞時，它指的是與凍土有關的或受凍而變硬的物體，如“frozen soil samples”（凍土樣本）。
凍土的近義詞包括：permafrost（永久凍土）、frost-bound（冰封的）、frosty soil（凍結土壤）等。
凍土的反義詞為：unfrozen soil（未凍結土壤）、thawed soil（融化的土壤）、soft soil（松散的土壤）等。
凍結（frozen）指的是液體或固體物質在低溫條件下變為固體狀态的過程。它與凍土的區别在于，凍結是一個過程，而凍土是一種狀态。凍結可以發生在不同的物質上，如水、土壤、食物等。
凍結可以用作動詞或形容詞。作為動詞時，它指的是物質在低溫條件下變為固體狀态的過程，如在例句中所示。作為形容詞時，它指的是已經被凍結的物質。例如，“frozen food”（冷凍食品）。
凍結的近義詞包括：freeze（凍結）、solidify（固化）、crystallize（結晶）等。
凍結的反義詞為：melt（融化）、thaw（解凍）、liquify（液化）等。
