Influence of low energy He Ne laser on spinal motor nerve cell .

低能量-氖激光对脊髓运动神经细胞的影响。

The results show that the atmosphere has a big influence on the thermal stability of C_(60).C_(60) begins to decompose at 423.5℃in the air,the deomposed peak temperature is 668.5℃,but very stable in the helium atmosphere,only sublimate,the crystal shape of C_(60) has a certain influence to its thermal stability.The synthesized nine kinds of nitro-fullerene derivatives all have good thermal stability and their decomposed peak temperatures all exceed 350℃.The thermal explosion temperature for 5 seconds delay of product 4 is 253℃.The category,number and position of nitryl group in nitro-fullerene derivatives all have influence on their thermal stability.

利用差热分析仪和DSC-TG综合热分析仪对C_(60)及其硝基衍生物的热稳定性进行了研究,结果表明,环境气氛对C_(60)热稳定性影响很大,C_(60)在空气中423.5℃开始分解,放热峰值温度为668.5℃,在气中很稳定,仅表现为升华,C_(60)的晶型对其热稳定性也有一定的影响;合成得到的九种硝基富勒烯衍生物都具有较好的热稳定性,分解峰值温度均高于350℃;产物4的5秒爆发点测试结果为253℃。
