A large range of IRZ and intense fluctuating velocity area around the boundary of IRZ is measured and thought to be important to keep the excellent ignition and combustion characters of the new kind swirl burner. Together with temperature trace method, different structure and operation parameter of the burner are studied in this paper about their effects on turbulent and mixing characters of swirling jet. The structure variation includes different blade angle, use of central gear shape baffle, variable outer length and angle of lean primary air outlet, use of wedge outlet of lean primary air.

在中国，权力大到不受控制，掌握生死大权的人要么等同于我上面所说的向较远的中心脉动；要么，等同于中国道德史学家和大家都用的"混乱"、"乱"-----或者"暗"-----一个道德败坏，充满剥削，没有节制的世界需要中心来恢复秩序。

K: So , first we have to get feeling with our board , start doing one foot exercises on the floor before take the lift , don't have fear and feel positive , you have to listen to the feedback from your feet and use the edges (back / front) correctly on the snow , before start you have to be able to brake the board ..

想滑得好，你必须要能抓到板子的感觉；上 lift 前先在家里练习单脚站立，下 lift 会比较轻松；学滑雪之前，先学会煞车；用心体会从板子传到你脚上的脉动，正确地使用板边来操控滑雪；心理建设是很重要的一环，别害怕，摔跤是必然的，打不过它，就用愉快的心情来面对它；只要你有心，就一定会进步，其实 90%的困难都是你自己在吓自己，没那麼困难的啦
