This paper referred to simulating the supersonic double cone inlet" s flow field of ramjet pill assisted range projectiles at a variety of working circumstances, pressure contours, density contours and Mach number contours of inlet" s flow field were given When cone combination, relative location of cone core and cowl lip, the pressure of outlet, inflow Mach number and angle were changed, flow field and performance parameters of inlet can be affected. Simultaneity, productive mechanism and inducing factors of the inlet surge were also discussed. Then the best working conditions and the best model of inlet were obtained.

But in China, people describe the students' goals as not democracy , per se, but as the end to corruption, the ability to air grievances, and the right to more control over their lives (or, as one person put it, the right to refuse to be shipped off to some dumpy factory for 40 years—a fate that would drive anyone into the streets).

但是在中国，人们并不认为这场学生运动的目的是为了民主，而是，从本质上讲，是为了腐败的终结，获悉真相的能力，以及更多的控制他们自身生活的权利（或者，正如有人所说的，为了拒绝被遣送到一些条件恶劣工厂工作40年——一种能使任何人绝望的命运的权利）。
