Maryland and the surrounding confusion compared to other cities: the color of buildings, how would like to brush on how brush; had momentary excitement Qingyang Road, not a complete outline of the horizon line, developers here take the greatest volume rate; To date, no claim to be an architectural landmark building in Lanzhou.
马里兰州和周围的混乱相比,其他城市:颜色的建筑,如何想如何刷子刷;曾一时兴奋庆阳路,而不是一个完整的轮廓线的地平线,开发商在这里采取的最大容积率;迄今为止,没有人声称是一个里程碑式的建筑在兰州建立。

A large number of results from the study indicate that there is a close connection between stock price and trading volume. This paper uses econometric tools, draws on the plasticity and elastic conceptions in the mechanics fields and considers the relation between stock prices and trading volume in different aspects, in order to set up complete stock price plasticity and elasticity theory and apply this theory by carrying on empirical researches.
首先,本文介绍了股价波动的塑性和弹性理论的思想来源,定义股票均衡价格、股价塑性、股价弹性等新概念,通过选取某些个股在不同时段上的股价和成交量的走势图,分别说明了塑性和弹性现象的存在;然后建立了股价的塑性模型、弹性模型及弹塑性交叉模型,应用计量经济学方法对这些模型进行参数估计和检验,对模型进行理论解释,分析模型与现有投资分析理论的一致性;最后是对股票价格塑性模型和弹性模型的应用研究。

The purpose of this study was to examine the difference between using bladder scan and catheterization on 87 rehabilitation patients to evaluation the amount of residual urine. After voiding, each subject was scanned with a BladderScan BVI 3000, then catheterized for postvoid residual urine volume. Repeat measure ANOVA analysis showed that the factors of gender, diagnosis, posture, the thickness of abdominal fat, bladder shape, the amount of urine, and the interval of operation time have no difference in this study. It takes 45 ± 18 seconds (range: 17-119) to accomplish a bladder scan, and it takes 280 ±106 seconds (range: 136-664) for nursing staff to complete a catheterization for patient. However, the catheterization process takes nursing staff 3-8 times longer then operating a bladder scan. This would diminish unnecessary catheterization and save on medical staff resources.
本研究对87位需做余尿量评估的复健病人,在排尿后以膀胱超音波BVI 3000机型测量扫描余尿量,然后接著给予间歇导尿,以repeat measures ANOVA分析,结果发现膀胱超音波及导尿测量所得尿量是无差异(F=0.38 p=。68),再以性别、诊断、姿势、腹部脂肪厚度、膀胱形状、尿量、操作间隔时间等因素做分析,以repeat measures ANOVA检定亦无差异,同时测量两种测量方法所花费护理时数:膀胱超音波平均为45±18秒(range: 17-119秒),导尿为平均280±106秒(range: 136-664秒),结论是膀胱超音波与导尿方式对余尿量的测量一样好,膀胱超音波与导尿时间相差约3-8倍的护理时数,先以超音波来测量余尿量可以减少不必要的导尿次数及节省医疗人力成本。
