Results: Everyone's center of gravity was distributed in A zone while they were in seat. At standing with opening eyes and closing eyes, the center of gravity in A zone were in 429 subjects( 96.4%) and 436 subjects( 98.0%). Most parameters have significant difference in the women and the men, opening eyes and closing eyes, left-foot standing and right-foot standing, different age groups. The stability in closing eyes was better than in opening eyes, right foot standing was better than left foot standing.

Please not that a 250 mm wide die opening will produce a film or sheet with less width since you have a "neck in" effect when you pull out the melted resin from the die before it reaches the surface of the chill roll. the width you can achieve depends on the melt strength of the resin as well as the distance between the die lip opening and the chill roll. but in general, about 80% of the die opening width can be achieved.

注意：250毫米宽开口的模头只能获得小于此宽度的薄膜或片材，因为当熔体树脂被从模头拉至冷辊上时会产生&颈缩&效应，最终获得的实际宽度依赖于树脂的熔体强度以及模唇开口同冷辊之间的距离，但总而言之，可获得模头开口宽度80%的产品宽度。
