查询词典 first quartile

Following is the main contribution of the dissertation. 1 Based on quartile and first order differential, a new outlier detection algorithm is presented, Experiments show that the method combining with low pass filter can remove gross error and unwanted frequency components.

本文的主要工作与创新点在于： 1）将分位数方法与一阶差分法相结合，提出了一种基于一阶差分的粗差剔除方法，该方法与低通滤波器的结合可以有效去除两相流压力波动信号中的粗大误差以及信号频带以外的频率成分。

Mild" outliers – that is, those observations which lie more than 1.5 times the IQR from the first and third quartile but are not also extreme outliers are indicated by the presence of an open dot."

温和的"外围之物- i.e，说谎超过1.5倍IQR从第一和第三方照，但的那些观察不是极端外围之物由一个开放小点的出现也表示。"

After adjustment for age, Killip class, and reperfusion status, compared with patients in the first aldosterone quartile group, those in the highest quartile were at higher risk of death (hazard ratio 3.28, 95% CI 1.09 to 9.89, P=0.035) and resuscitated cardiac arrest (hazard ratio 3.74, 95% CI 1.40 to 9.98, P=0.008)during the follow-up.

在对年龄，KILLIP分级和再灌注治疗等因素进行了调整之后，我们发现与低血浆醛固酮水平患者相比，高血浆醛固酮水平者有较高的死亡风险（危险比3.28， 95% CI 1.09 to 9.89， P=0.035）和随访期间较高的心跳骤停发生率(危险比 3.74， 95% CI 1.40 to 9.98， P=0.008)。

In adjusted models, NRG-1β was independently associated with an increased risk of death or cardiac transplantation over a median follow-up of 2.4 years (adjusted hazard ratio, 1.58; 95% confidence interval, 1.04 to 2.39; P=0.03 comparing fourth versus first NRG-1β quartile).

在校正的模型中，NRG-1β与死亡风险增加或心脏移植独立相关（平均随访2.4年，NRG-1β第四分位数与第一分位数相比，校正的风险比为1.58；95% CI，1.04~2.39；P=0.03）。

Extreme outliers, or those which lie more than three times the Inter quartile range from the first and third quartiles, respectively , are indicated by the presence of an asterisk.

极端超过说谎的外围之物或者那些三倍相互方照范围从第一和第三方照，分别，由星号的出现表示。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
