In the present work, based on the mechanism of low-temperature corrosion, an opinion was presented by theoretical analysis and computation, that is the vacuum boiler can not avoid being corroded completely under low temperature, but the corrosion is very weak no matter if the exhaust gas temperature is higher than the flue gas dew point; it was obtained the relationship between the corrosion velocity of metal wall and wall temperature along gas pass of vacuum boiler, and the one between the corrosion velocity of metal wall and wall temperature under the condition that the flue gas temperature is lower than the acid dew point.

本文从锅炉发生低温腐蚀的机理入手，通过理论分析计算并通过实践检验，提出了真空相变锅炉虽然不能完全避免低温腐蚀问题，但不论排烟温度是否高于烟气露点，低温腐蚀的程度都很弱的观点；给出了真空相变锅炉沿烟气流程金属壁面的腐蚀速度与壁面温度的关系曲线，和烟气温度低于酸露点时金属壁面的腐蚀速度与壁面温度的关系曲线；笔者专门从事真空相变锅炉的设计研究已十多年，根据上述观点设计的数百台产品已经过多年实际运行，未发现明显低温腐蚀。

Cryopreservation is an important technology in the field of cryobiology. Nowdays, the quick development of cryopreservation brings great progress. The cryopreservation of tissue isn''t satisfactory yet.It is the key that resolve the damage of hypothermia.

低温保存是低温生物学研究中的一项重要技术，近年来低温保存技术的迅速发展为临床医学带来了许多突破性的进展，但组织的保存并不十分理想，其关键在于解决低温的损伤作用。

And 67. 5% in Xiangnuo 1 and IR50 respectively when they were under chilling for 2days. Chlorophyll fluorescence data showed that the reaction centers with less accumulation of redundant exciting energy and antenna systems in Xiangnuo 1 were less injured under chilling, with higher qP and qNP which were used to dissipate the redundant exciting energy, and protect the reaction centers from chilling injury. Lower qP and higher Ex as well as decreasing qNP in chilling-susceptible cultivars indicated that its reaction centers and antenna systems were damaged severely by chilling, leading to the lower photosynthetic rate.

叶绿素荧光分析的结果表明，低温下湘糯1号PSII反应中心和天线系统受到的伤害轻，反应中心过剩激发能积累少，可藉较高的qP和qNP进行过剩光能的耗散，保护光合机构免受低温伤害，而冷敏感品种qP下降快，Ex增加较多，但qNP却随低温延长而下降，说明它的反应中心和天线系统都受到了严重的低温伤害，导致光合能力下降。
