according to the mechanism of bitter formation, the bitter taste masking technology is classified into different sorts from different taches that disturb the bitterness formation, include adding the taste correcting substance to confuse the cerebral taste; staving or preventing the drug releasing in mouth and segregating the contact between drug and taste buds; anesthetizing the taste cell to enhance the threshold of bitter taking; preventing bitter taste receptor combining with bitter blocker, cutting off the signal transduction pathways etc.summerize the methods of taste masking technology,besides,describe the method's advantages and disadvantages, and the technology of preparation.provide academic direction for the reasonable use of bitterness taste masking.

依据苦味形成机理，从干扰苦味形成的不同环节将中药苦味掩味技术分为添加矫味剂，混淆大脑味觉掩盖药物苦味；延缓或阻止药物在口腔释放，隔离药物和味蕾的接触；麻痹味觉细胞，提高苦味感受阈值；阻止苦味受体与苦味剂的结合，切断信号传导掩盖苦味等4类，综述掩盖中药苦味的方法，并简述各方法的优缺点和制备技术，为合理应用苦味掩味技术提供理论指导。

There are experimental results as follows:(1) Eriophorum comosum Nees shows strong cold resistance in plasmalemma permeability research. The lethal temperature of Eriophorum comosum Nees is the lowest LT_(50 in comparison with another two plants and is lower than -11.5℃ in August 2005 and December 2005; Soluble protein content of each plant is rising before or after cold hardiness. By SDS-PAGE, Protein band is analysed. Band quantity of Eriophorum comosum Nees is the most and its band color is darkest.(2) Soluble sugar content of three plants after cold hardiness are higher than before cold hardiness, moreover soluble sugar content after cold hardiness shows a decline and there is a narrow range in Eriophorum comosum Nees; Free Proline accumulation is changed by cold stress, and cold resistance is relative to free Proline accumulation; chlorophyll content of both three plants, including chlorophyll a, chlorophyll b and chlorophyll a/b, show a decline tendency along with the descent of temperature. Cynodon dactylon is highly sensitive to cold stress.(3) The soil POD and urease activities' absolute value of Erioophorum comosum Nees and Pogonatherum panideumHack were more than that of Cynodon dactylon before or after low temperature stress, especially POD activities.

实验结果表明：(1)在膜透性的研究中，丛毛羊胡子草抗寒性最强，采用电导率法测得半致死温度LT_(50最低，丛毛羊胡子草抗寒锻炼前后半致死温度LT_(50均小于-11.5℃；在可溶性蛋白含量研究中，抗寒锻炼前后三种植物的可溶性蛋白含量均增加，同时采用SDS-PAGE法，通过对蛋白条带分析，以丛毛羊胡子草条带数最多且着色深；(2)在可溶性糖的研究中，三种植物经抗寒锻炼后叶片可溶性糖含量都比抗寒锻炼前高，且经过抗寒锻炼后三种植物可溶性糖均呈下降趋势，丛毛羊胡子草可溶性糖含量下降较小；从游离脯氨酸含量可知，低温的胁迫影响了植物叶片游离脯氨酸的含量变化，植物的抗寒性与游离脯氨酸有关；低温胁迫下三种植物叶绿素含量随着温度的下降，叶绿素含量、叶绿素a、叶绿素b和叶绿素a／b均呈下降趋势，狗牙根对低温胁迫最为敏感；(3)低温锻炼前后，丛毛羊胡子草和金发草的土壤过氧化物酶与脲酶活性的绝对值均大于狗牙根的，特别是过氧化物酶，说明丛毛羊胡子草和金发草的酶活性大于狗牙根的。
