在国内本实验是第一个研究下降环腔内的流动与传热，在国际上，象这样同时进行了流动可视化，常温常压下传热和高温高压下传热的实验也不多，特别是针对下降环腔内对流换热系数的研究，在公开文献中还没有相类似的实验。

Injection of rhIL-2 (200,100,50,25,12. 5 ku/kg) can inhibit mouse ear swelling, especially when dosage is 25～50 ku/kg. Injection of rhIL-2 (25 ku/kg) can inhibit rat plantar swelling. The function of mononuclear macrophage system was strengthened by hypodermic injection of rhIL-2( 100 ku/kg) once a day for 9 days. The decrease of mouse delayed-type hypersensitivity reaction induced by cyclophosphamide was extenuated by hypodermic injection of rhIL-2(50 ku/kg) once a day for 6 days. IL-2 has anti-inflammatory effects and immunomodulatory effects when administered in certain dosage.

The effects of port injected n-heptane equivalence ratio and iso-octane direct injection timing are investigated experimentally and numerically. The results indicate that the combustion mode of iso-octane is dependant on the iso-octane direct injection timing corresponding to the stage of n-heptane HCCI combustion. In case of direct injection before the low temperature reaction of n-heptane, premixed combustion of the iso-octane occurs. In case of direct injection at the NTC period or the initial high temperature reaction stage of n-heptane, the iso-octane mainly undergoes premixed combustion.
