More children with headaches were in the highest quintile of risk for these factors, as well as in the highest quintile of risk of having at least 3 or more of these factors.

更多有头痛的儿童，他们这些因子的风险处於最高的四分位数，且有3种以上这些因子的风险也是最高的。

At least half of participants who were in the top quintile of glucose homeostasis variables in childhood were above the 60th percentile for these variables in adulthood.

在儿童血糖恒定变项四分位数最高的受试者中，至少有一半在成人时，这些变项超过所有受试者的60%以上。

In the special case of GLM—normal linear model with classical link function,we compare our methods with existing ones and our methods perform more excellently.Finally,sequential detection of structural changes is studied in nonparametric regression models o Based on Nadaraya-Watson estimator of regression function,we calculate the residual series and construct "residual cumulative sum process" with weight values of kernel estimator of "long-run average density function".

在随机模拟一节中，给出了布朗桥的h-增量过程的"Max-Max"泛函统计量的经验分位数表，并在随机模拟中验证了文中所提"部分和"与"滑动和"方法的有效性，同时在广义线性模型取"典则连接函数"时的特例—正态线性模型场合，与已有方法进行了对比，结果显示文中所提方法表现更优。

"We decided to quantify the calcium findings in the aorta and stratify calcium by total score, as well as scores in suprarenal, laminar, and bifurcation segments," Dr. Davila said. In general, the highest calcium scores were found in the laminar area, but "these scores did not correlate with a statistically significant increased risk." By contrast, a total calcium score or bifurcation score above the 75th percentile "correlated with a 10-fold increase in risk of cardiac event," he said.

Davila医师表示，我们决定主动脉钙含量的发现、利用总分来分类钙含量，以及肾脏上方、薄层、分支区段的指数；一般而言，指数最高的位置在於层状区域，但是这些指数与心血管风险的增加之间并没有显著的关连；相反的，总钙含量指数或是分支区段指数高於四分位数前75%者，与增加10倍心血管疾病的风险有关。

This paper mesents the method that can calculate concrete compressive strength of non-batch member through its 5% fractile and revising coefficient if its material strength is in obedience to normal distribution.

本文结合工程实例提出对材料强度为正态分布的非批构件按其分布5%分位数并考虑样本容量修正系数确定构件混凝土强度推定值的方法。

In this paper the errors in formula (2) are detected by analysis made on the principle of area substitution,and methods for reducing errors is presented which are capable of a higher degree of accuracy in maximum proximation for Gaussian distribu- tion and fractile formula.

从而得到精度很高的 Gauss 分布函数极大迫近式和分位数公式，并指出精确度明显优于 Hastings 和 Shannelerlan 公式。

Intratest variability and intrasession CV represented 79.1% to 98.6% and 77.1% to 95.0% of test-retest variability and intervisit CV, respectively, for the average and quadrant RNFLT and the GCC parameters.

对于平均和四分位数RNFLT和GCC参数，测试间变异性和期间CV中再测试变异和访视间CV占79.1％至98.6％和77.1％至95.0％。

Subjects with plasma Aβ42/Aβ40 ratios in the lower quartiles showed significantly greater risk of MCI orAD(P=.04, adjusted for age and apolipoprotein E genotype).

血浆Aβ42/Aβ40比值在下四分位数者，MCI或AD的患病风险明显增高(P=0.04，按年龄和载脂蛋白E基因型进行校正)。

Quantile estimation using the extended P^2 algorithm for weighted and unweighted samples.

分位数预估对加权和非加权样本使用了扩展的 P^2 算法。

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。
