在1 Au处，对Imp 6合并的等离子体和磁场数据的前4个月进行了搜索，以寻找太阳风热通量（Q）局部调节的证据。从几个延长时间段的数据以及统计分析表明，阿尔芬速度有时是Q的主要调节因子，其关系为Q ΔVc = αVA。其中ΔVc是低能电子峰值与体等离子体速度之间的速度差，VA是局部阿尔芬速度，α是1阶无量纲参数。
The first 4 months of Imp 6 merged plasma and magnetic field data have been searched for evidence of local regulation of the solar wind heat flux (Q) at 1 AU. Data from several extended time periods as well as a statistical analysis suggest that the Alfven speed is at times a prime regulating factor of Q through the relation Q ∝ ΔVc = αVA. Here ΔVc is the velocity difference between the peak of the low-energy electrons and the bulk plasma velocity, VA is the local Alfven speed, and α is a dimensionless parameter of order 1.
