1. 含义和定义
LCST是英文 "lower critical solution temperature" 的缩写，中文意为“下临界溶液温度”。指的是溶液在一定条件下的温度，低于此温度时，溶液是一种透明的单相液体，高于此温度时，溶液则会分成两个相，即水相和聚合物相。
2. 应用领域
LCST在材料科学、高分子化学等领域被广泛应用。比如，可以用于制备智能材料，如控释型药物递送器、可逆荧光探针、可操控的液晶等等。
3. 形成机理
LCST的形成机理是由于随着温度的升高，溶液体系中的热运动加剧，导致聚合物的自由度增加，聚合物链间相互排斥作用增强，导致聚合物相互聚集，最终形成了两相体系。
4. 实验研究方法
常用的实验研究方法包括：荧光光谱法、紫外可见光谱法、动态光散射(DLS)、差示扫描量热法(DSC)、核磁共振(NMR)等。
5. 相关术语
与LCST相关的术语还有：UCST（upper critical solution temperature）上临界溶液温度、TLCST（thermoresponsive lower critical solution temperature）热敏下临界溶液温度、TCP（temperature-controlled phase transition）温度控制相转移等。
中英例句：
1. The LCST of this copolymer was found to be 13 ℃ in a water/ethanol mixture.
这种共聚物在水/乙醇混合物中的LCST为13℃。
2. The LCST behavior of this hydrogel can be modulated by varying the pH value of the solution.
通过改变溶液的pH值，可以调控这种水凝胶的LCST性质。
3. The LCST phenomenon is a typical phase separation behavior of polymer solutions.
LCST现象是聚合物溶液的典型相分离行为。
4. The DLS results showed that the nanoparticle dispersions above the LCST exhibited a remarkable increase in particle size.
DLS结果表明，在LCST以上的纳米颗粒分散液中，颗粒大小显著增加。
5. The thermoresponsive polymers with a TLCST in the range of 20-30 ℃ have attracted extensive attention.
TLCST在20-30℃范围内的热敏聚合物引起了广泛的关注。
lcst的中文翻译是“最长公共子序列”。读音为“艾尔西艾提”。
例句：
1. 计算机科学中的lcst问题是一个非常重要的问题。
2. 在机器学习中，我们经常需要计算两个序列之间的lcst。
Translation:
The Chinese translation of lcst is "最长公共子序列", and its pronunciation is "ài ěr xī ài tí".

2. In machine learning, we often need to calculate the lcst between two sequences.
lcst通常被翻译为"临界溶液温度、线路控制选择表"的意思，在英美地区还有"低临界溶解温度"的意思，发音音标为[lcst]，在英语中以名词出现较多，在《英汉简明词典》中，共找到60个与lcst相关的句子。
