线心线心
  1. 线心都可以看作是Doppler加宽;

    The line center of HeI 10830 A line can be taken as Doppler broadening .

  2. 以往对K线的研究表明:K1形成于温度极小区(TMR),K1到线心的距离以及K1的强度分别与温度极小区的位置和温度密切相关。

    It is now widely accepted that K 1 is formed in the temperature minimum region ( TMR ) and that the distance of the component K 1 from the line center and the intensity of K 1 is well related to the position and temperature of TMR , respectively .

  3. 测试结果表明:NiO纳米线为面心立方结构,平均晶粒尺寸为50nm,纳米线直径约90nm,与模板孔径相当;

    XRD results indicate that the NiO nanowire has a face-cubic structure and its average crystal size is about 50 nm . According to SEM , the diameter of the NiO nanowires is about 90 nm , equivalent to the diameter of template pores ;

  4. 通过半经验半理论的方法对射流z轴方向流速分量w等值线流团涡心运动轨迹方程进行了推导,分别建立了涡心运动轨迹x分量与z分量随时间变化的表达式。

    Deduced the track formulas of the jet flow velocity z component w isoline patch vortexes centers movement , and through semi-empirical method , got vortexes centers movement track x component and z component equation with time .
