Coagulants的英文詞源是拉丁語“coagulum”，意為凝固。這個詞來源于“coagere”，意為“凝固”。

Coagulants的變化形式有：

1. Coagulation - 凝固，凝結

2. Coagulable - 可凝固的

3. Coagulate - 凝固，凝結

4. Coagulase - 凝固酶

5. Fibrinogen - 纖維蛋白原

6. Fibrin - 纖維蛋白

7. Fibrinolysis - 纖維蛋白溶解

8. Coagulopathy - 凝固障礙

9. Hemocoagulation - 血液凝固

10. Thrombin - 凝血酶

Coagulants在生物學和醫學中用于促進血液凝固，防止血液流失，有助于止血。同時，在化學和工業中，它們也常用于水處理和廢水處理，以防止懸浮物泄漏。它們在食品工業中也被用于食品加工，以防止食品中的液體泄漏。

常用短語：

1. coagulation agent 凝固劑

2. coagulant solution 凝固溶液

3. coagulate water 凝固水

4. coagulate water agent 凝固水劑

5. coagulate water additive 凝固水添加劑

6. coagulant chemical 凝固化學物質

7. coagulant water treatment 凝固水處理

英文小作文：

Coagulants play an important role in water treatment, helping to improve the quality of water and reduce the amount of sludge generated during treatment processes. From small domestic systems to large-scale industrial facilities, coagulants are commonly used to ensure effective and efficient water treatment systems. By using a coagulant, water treatment systems can achieve higher levels of clarity and quality, reducing the occurrence of turbidity and other problems that can arise during water treatment processes. Additionally, coagulants can also help to improve the stability and efficiency of water treatment equipment, reducing maintenance costs and ensuring that systems continue to operate effectively and reliably. Ultimately, the use of coagulants can help to reduce the cost of water treatment while maintaining high levels of productivity and efficiency.
