To sum up, the research for the first time ascertained INA species in apricot trees and their activities by using the rational method to imatate the temperature dropping process in frost nights--computer temperature controlling with semiconductor cooling and artificial frost box with self-recording. Studies were given to responds of INA to freezing temperature of floral organs, biochemical cold resistance parameters, contents of ABA and IAA, chlorophyll fluorescent parameters of young fruits and tissue structure and ultrastructure of apricot. The mechnism of INA induced frost injury of apricot was found out. And it was demonstrated that INA is a critical factor in the inducing and aggravation frost injury of apricot floral organs.

综上所述，本研究采用能够准确模拟自然界霜夜降温过程的较为理想的方法——半导体致冷电脑控温和自动记录的人工霜箱，首次查明了10个杏树品种上INA细菌种类和冰核活性，从INA细菌对杏树花器官过冷却点、抗寒生理生化指标、激素ABA、IAA含量、幼果叶绿素荧光参数以及组织结构和超微结构的影响等方面进行了系统深入的研究，阐明了INA细菌诱发杏树霜冻害的机理，证明了INA细菌是诱发和加重杏花霜冻害的重要因素。

In order to inquire the causes of occurrence of lipoid pneumonia in rat that were raised in standard SPF animal reproductive area, we used self-reproducing standard SPF rats, male 50 and female 50. All of the rats were divided into 10 groups, raised in standard Barrier system, and fed the standard diets imported from U.S.A.. All animals were divided into 4 stages to sacrifice. Autopsy, histopathological and blood biochemical examination were made at each stage. The results reveal that no lipoid pneumonia were found to occur in the 5, 10 and 26-week-old groups of male and female rats. 40% of male and 60% of female were found to occur slight focal lipoid pneumonia in the 52-week-old groups of rats.
