为了定量分析车辆的侧翻倾向,必需开发一变工况下预测车辆侧翻可靠的动态测试方法。本文介绍车辆侧翻稳定性方面已经开发的动态测试的一些成果。开发车辆侧翻倾向的测试,必需首先确定车辆侧翻所绕的轴线(侧翻轴)的位置。为此应首先进行中心轴概念的研究。如本文所述表明,车辆中心轴位置是不可预测的,导致三种可能的侧翻轴的分析,要进行车辆系统的动能和势能,和其部件变形造成的结果以及过去开发的能量基础函数所谓侧翻防止能量储备(RPER)的研究。RPER的定义为车辆到达侧翻位置所需的能量和车辆回转运动能量可转换成举升车辆的重势的差值。根据这种定义,在车辆侧翻情况下,在到达侧翻位置前,RPER函数值应降至零,通常在非侧翻情况RPER常为正值。本文介绍了开发的计算RPER的算式。RPER函数已经被Missouri-Col.mbia大学,采用全尺寸6辆轻型货车,箱式载货车和轻型箱式越野车辆以及二辆轿车,在不同的控制和侧翻掉纵过程的扩展试验获得的试验结果证实。试验时还采用的路边几何状况,包括路面铺土到铺石子的过渡段。本文对两侧翻和非侧翻情况绘出RPER的性能曲线。

具有美学属性的眼周区域(包括眼睛、眼睑、睫毛和眉毛)一直以来都是人类面部吸引力的核心,也因此而衍生了众多修饰性的化妆品。欧莱雅集团在其中国、法国、印度、日本、南非和美国的6个研发中心对不同年龄、种族女性的3600张高清眼部照片进行了分析,获得了不同种族女性人群的眼部定量参数(眼睛形状,即高度、宽度、椭圆度/倾斜度以及相对鼻中轴的位置等),呈现了其多样性。结果显示,女性虹膜的直径几乎恒定(约11.7~12.4 mm),黑色和褐色虹膜最为常见。作为一种常见的X-常染色体易位现象,内眦赘皮更常见于亚洲志愿者中。

Journal.of Energy and Power Engineering 2010年第7期4卷 9-14页

In partial.y premixed combustion of gas turbine, the combustion temperature shoul. be l.wed in order to reduce NOx. One sol.tion is l.an premixed combustion. However, the probl.m is that l.rge excess air ratio may make the combustion unstabl.. A novel.combustor with circumferential.reverse fl.w of fuel.gas is proposed for settl.ng this probl.m. A 10 kw furnace is establ.shed to test performance of this combustor. Three factors such as primary air ratio, position of secondary air, total.excess air ratio are studied. The emission characteristics and axial.fl.me temperature distribution are studied. Basing on experimental.resul.s, the axial.fl.me temperature and NOr emission increase with primary air ratio and axial.l.ngth of second stream, and decrease with total.excess air ratio. When the total.excess air ratio is l.rger than 1.05, the combustor presents a l.wer temperature fiel. and much l.wer NOx emission （l.ss than 10 ppm）.
