Input-layer contains seven nerve cells (sailor average maritime experience、average shipping years、average standard wind days、average river velocity 、visibility、water depth and traffic density) and output-layer contains four nerve cells (great accident、large accident、common accident and small accident).The test that use the data of historical occurrence level of maritime accidents in ChongQing water area is done, the result shows the feasibility of the predictive model.

最后本文用VC++制作界面，基于MATLAB的神经网络工具箱建立了水上交通事故的BP神经网络预测系统，采取三层BP神经网络，输入层有7个输入神经元(船员平均水上资历、平均船龄、平均标准风天数、水域平均流速、能见度、水深和交通密度)，输出层有4个神经元(重大事故、大事故、一般事故和小事故)，并通过对长江干线重庆水域的预测来检验模型的效果。

The results revealed a reduction of ICU stay after intensivist staffing, but there was no significant difference in the mortality rate.

结果显示，在实施了专责重症医师照护后，病患的加护病房平均住院天数降低，但是在死亡率上，则不呈现统计上的差异。

This study collected data from 1650 patients, retrospectively from a surgical intensive care unit at a teaching hospital from July, 2002 to June, 2004 to determine whether the presence of an on-site, organized, intensivist critical care service improved care and decreased resource utilization.

这篇研究的目的是对一所教学医院外科加护病房实施专责重症医师照护前后，对於病患照护成效，以加护病房住院天数以及死亡率的变化作了实施专责重症医师照护前后的成效评估。

An independent sample t-test and a one way ANOVA test were used to compare the differences between an ICU stay 1 year before and 1 year after intensivist staffing in July 2003. A Chi-square test was used to analyze the association of mortality.

使用独立样本t-检定及单因子变异数分析来比较实施专责重症医师照护前后在住院天数是否有所不同；利用卡方检定来检查和死亡率有关的因素。

The major index were patient APACHEII Score≧25 (within 24 hours of ICU admission), survival rate, the length of ICU stay, and whether intensivist care had been received; the care efficacy was evaluated and tested by chi-square test and independent sample t-test.

主要指标为患者的疾病严重度分数≧25分者（入院24小时内之APACHE-II Score）、存活率、住加护病房天数、是否接受专责重症专科医师照护，并以卡方检定、独立样本t检定来进行照护成效评估。

The potential cost saving, in particular, has garnered much attention. One estimate, based on an outlay of $0.04 per stick of chewing gum, an estimate of 79,219 colectomies per year, and a mean cost of hospital stay of $1500 per day, suggests that if it were to reduce the length of hospital stay by 1 day, this intervention could result in savings of nearly $119 million annually in the United States Arch Surg .

尤其所能省下潜在的费用更是吸引人的目光；一项研究估计，根据每条口香糖0.04块美金的费用计算，再以每年进行79，219次大肠切除术的数字来看，每天住院的平均费用为1500块美金，显示如果可以减少一天的住院天数，该介入在美国每年将可以节省1亿1900万美金

The perpetual calendar displays a calendar for any month of any year, and the Multiple tool calculates the number of days, weeks and years between a series of events.

永恒的日历显示日历的任何一个月的任何一年，和多元的工具，计算天数，周和年之间的一系列活动。

Two (8%) patients ultimately required mitral valve replacement for recurrent mitral insufficiency.

最初手术的10例患者与后15例患者比较，后者耗时明显缩短：总手术室停留时间分别为318.5分钟和275.1分钟；夹闭时间，97.6对81.1分钟；后瓣切除或修补26.2对15.6分钟；瓣膜成形术，31.9对24.8分钟；住院天数分别为4.2和1.67天。5例患者术后出现房颤，2例患者（占8%）因最终出现二尖瓣功能不全而进行了瓣膜置换术。

However, the contents of Noradrenaline and Dopamine were detected in the culture mediums which were cultured for 10, 14 and 30 days by HPLC.

Asp方差分析显示：随着BMSCs培养天数的增加，培养基中所含的NE和DA无显著性差异（P＞0.05）。

Count the number of upside penetrations during the lookback period, in this case 10 days.

记下本例10天中，上涨穿过的天数。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
