The changes of freezing point and super-cooling point of a series of PM vitrification solutions was investigated in the process of slow freezing at a ratio of 5℃/min. This experiment showed that the vitrification solution over 41% had not freezing point, while the vitrification solution under 40% had freezing point and could ice.

对PM系列玻璃化液在5℃/min慢速降温过程中冰点、过冷点的产生和变化进行研究，发现浓度在41%以上的玻璃化液降温时不产生冰点结晶，而40%以下玻璃化液在慢速降温时在冰点出现了结晶。

This effect is probably related to the interaction between amorphous PE in PP copolymer and PE phase in mPE and EPDM. T〓 of mPE decreases with increasing the octene content, and maximum damping of the glass transition relaxation increases.

PP／SEBS共混物中SEBS的玻璃化温度随SEBS含量的增加而降低，表明共聚PP中的PE相对SEBS中丁二烯嵌段的玻璃化松弛转变影响很小。mPE中的辛烯含量越高，其低温损耗峰的强度越高，玻璃化温度越低，低温韧性越好。

Two-component waterborne polyurethane paint composed of acrylic dispersion and hydrophilically-modified polyisocyanate has fast dry time, good adhesion, flexibility, impact resistance, but poor water and chemical-resistance. The dry time becomes shorter with the increase of glass transition temperature and the decrease of acid value; the gloss of the film decreases with the increases of hydroxyl value, acid value and Tg of emulsion polymer; higher Tg polymer leads to harder film.

将制得的丙烯酸分散体与亲水改性多异氰酸酯组分配制水性双组分聚氨酯涂料，发现漆膜表干和实干比较快，干燥时间随玻璃化温度升高而缩短，随酸值的增加而增加；附着力、柔韧性和冲击强度比较好；光泽随分散体羟值、酸值的增加和玻璃化温度升高而降低；硬度随玻璃化温度升高而升高；较高的酸值使涂料的耐化学品性和耐水性较差，羟值在100mgKOH/g时较好，而酸值应尽可能低。

Based on this relationship, we can change the Tg of starch by changing its molecular weight to meet the pratical needs.The DSC technique is used to estimate the consistence character of starch with different additives. The glass transition behavious of starch blended with water and Xanthan gum are examined respectively. An expirical expression is obtained for the Tg of starch blendee with additives according to the blending model of polymers and verified with the experimental results.

The endurance abilities of the embryos of sea perch, flounder and turbot at different developing stages to vitrification solutions were studied. The result showed that sea perch at tail-bud stage, heart-beating stage and pre-hatching stage had more endurance abilities to VSD2, flounder at 4-5 somites, 16-20 somites and tail-bud stage had more endurance abilities to PM3, and turbot at 4-5 somites, 16-20 somites and tail-bud stage had more endurance abilities to PMP1. The feasible equilibration time of three marine fish embryos in vitrification solutions was determined, which guided the dealing process before freezing.
