A survey of Schick's test was made in three village and towns among 1015 people whose ages and occupations were different,of whom 332 (32.71%) were positive.This showed that only about 67.29% of the total population had immunity.The immune level can't control diphtheria epidemic.If source of infection enters the area,an outbreak of diphtheria may occur.The positive rate between various age groups showed that there were remarkalbe differences (X~2=52.58,P<0.01).General tendency is that with increase in age positive...

A survey of Schick's test was made in three village and towns among 1015 people whose ages and occupations were different,of whom 332 (32.71%) were positive.This showed that only about 67.29% of the total population had immunity.The immune level can't control diphtheria epidemic.If source of infection enters the area,an outbreak of diphtheria may occur.The positive rate between various age groups showed that there were remarkalbe differences (X~2=52.58,P<0.01).General tendency is that with increase in age positive rate will goes down.This shows that it is important to protect chiildren below ten in our future immunity plan.Artificial positive rate in controlled group was very low (1.87%) and disappeared in 72 hours.So we think it unnecessary to have contrast groups.An observation after an interval of 96 hours has no effect on immune level.

本次对郯城县三处乡(镇)不同年龄和职业的1015人做了锡克氏试验观察,阳性332人(32.71%),这表明仅67.29%的人具有免疫力,尚达不到控制白喉流行的水平,一旦有传染源传入,仍有流行的可能。并显示各年龄(?)间阳性率有显著性差异(X~2=52.58,P<0.01),总的趋势是随着年龄的增长而阳性率降低,提示我们在今后的计划免疫中,应重点保护10岁以内儿童.关于锡克氏试验设对照方面,本次观察证明假阳性率很低(1.87%),并多于72小时内消失,故认为可不设对照,若在注射后96小时一次观察,并不影响免疫水平估计

This paper presents two new CFAR detectors based on Ordered Statistions(OS)and Cell-Averaging(CA)forming local estimates,using Greatest-of(GO)and Smallest-Of(SO) selection respectively to form interference power level estimate Z in test cell(OSCAGO.OSCASO).Under the Swerling Ⅱ assumption.we derive the analytic expressions of P_(fa).P_(cl) and ADT of the two detector,analyze its detection performance in homogeneous background and in strong interfering targets envi-ronment.and compare them with OS- GOSGO- GOSSO-CFARs. Results show that the detection performance of OSC AGO in homogeneous background and multiple target situations are all obvi-ously better than that of OS and GOSGO When the number of interfering targets is equal to certain value the CFAR losses of OSCAGO are about 3bB less those of GOSGO In homogeneous background.OSCASO possesses the similar performance to GOSSO But in multiple target situa-tions,the performance of OSCASO under certain conditions even exceeds that of OS and GOSGO

本文提出两种基于有序统计(OS)和单元平均(CA)产生局部估计,并分别应用最大选择(GO)和最小选择(SO)产生检测单元干扰功率水平估计Z的新的恒虚警检测器(OSCAGO)和(OSCASO)。我们推导出了它们在SwerlingⅡ型目标假设下的P_(fa),P_(cl)和度量ADT的解析表达式。分析了它们在均匀背景和强干扰目标环境之中的检测性能,并把它们与OS-、GOSGO-、GOSSO-CFAR进行了比较。结果表明,OSCGO在均匀干扰背景和多目标情况下的检测性能与OS和GOSGO相比,都有很明显的提高。在干扰目标数为某些值时,OSCAGO的CFAR损失比GOSGO小近3bB。在均匀背景中,OSCASO的检测性能与GOSSO相近。但是,在多目标环境中,一定条件下的OSCASO的检测性能甚至超过了OS和GOSGO。

The authors compared two dietary survey methods using the data from 1991 China Health and Nutrition Survey.

Data were collected over 3 consecutive days by 24hour dietary recall and a household inventory method for 3563 households with 13606 individuals. After using household cooking oil and condiments consumption to modify the individual recall results, there was only a 0. 31 MJ (74 kcal)difference between...

The authors compared two dietary survey methods using the data from 1991 China Health and Nutrition Survey. The objective of this study is to evaluate the accuracy of the 24-hour individual dietary recall method. Data were collected over 3 consecutive days by 24hour dietary recall and a household inventory method for 3563 households with 13606 individuals. After using household cooking oil and condiments consumption to modify the individual recall results, there was only a 0. 31 MJ (74 kcal)difference between these methods for average daily calorie intake. The relative difference was 1%. Rations were 5% and 2% for average daily protein and fat intake, respectively. Analysis of covariance was used to compare the means of the nutrients intake when adjusting for other confounding variables. The biggest difference was in households with guests eating at home,where fat intake was significantly higher, Particular importance was an adjustment for household cooking oil consumption used to modify the recall results. Removing this adjustment greatly expanded differences between these two methods.

利用1991年中国健康与营养调查中家庭膳食称重法和24h个人膳食询问法结果的准确性,通过对8省的3563户中13606名居民进行连续3天的24h个人膳食询问和家庭称重调查结果比较表明:在用全家称重法所得的食用油和其他调味品修正24h个人膳食询问结果后,两种方法平均每标准人日热能摄入仅相差0.31MJ,相对误差只有1%,蛋白质相对误差较大为5%,脂肪为3%。协方差分析比较除掉混杂因子的影响之后的标准人均每日几种营养素的摄入量,差别最大的是家中有客人的组,脂肪摄入明显较高。本研究说明,用全家称重法调查所得食用油的消耗量,对24h个人询问结果进行修正,调整了两种方法的差异,从而得到较准确的个人膳食及营养素的摄入水平估计
