Statistical analysis of the X-ray prop erties of 247 quasars in the 0.5-4.5 keV band observed from the Einstein Satellite,are carried out in this paper which is one of a series of papers devoting to the study of X-ray quasars and active galactic nuclei.The following main results are found:1.Among all the 1619 known quasars of various apparent magnitudes and red-shifts (or distances),those detected as X-ray sources are of nearly equal percentages.2.There exists a weak correlation between the optical radiation...

Statistical analysis of the X-ray prop erties of 247 quasars in the 0.5-4.5 keV band observed from the Einstein Satellite,are carried out in this paper which is one of a series of papers devoting to the study of X-ray quasars and active galactic nuclei.The following main results are found:1.Among all the 1619 known quasars of various apparent magnitudes and red-shifts (or distances),those detected as X-ray sources are of nearly equal percentages.2.There exists a weak correlation between the optical radiation and the X-ray radiation.The correlation coefficients in some cases are shown in Table 1,which shows clearly that the radio emission with frequencies higher than 2.5 GHz correlates strongly with X-ray radiation,implying that the emitting regions in these three bands (optical,high frequency radio anl X-ray bands) are close to one another in order and that their emitting mechanisms are similar.3.There is a strongly correlation between the radio RFW of equivalent widths of the emission lines Hβ and [OIII],and the X-ray luminosity Lx (0.5-4.5 keV) for type I Seyfert galaxies (Fig.10),whose properties are similar to those of radio-quiet quasars.We propose this correlation [equation (5.2)] as a new X-ray luminosity indicator for type I Seyfert galaxies.4.Neither the color index U-B nor B V correlates with X-ray radiation,but U-B correlates with B-V weakly.Acknowledgement: One of the authors (H.S.Yang) thanks Dr.G.Burbidge,Director of Kitt Peak National Observatory (Tucson,Arizona,U.S.A.),for many helpful discussions during his stay at KPNO where part of this work was done.Yang thanks also Mr.J.Wagner for help in using computer.

本文对247个类星体的X射线性质进行了统计分析,这些X射线资料是由爱因斯坦卫星在0.5—4.5keV的能带内观测到的。主要结果是:在各种视亮度和红移(或距离)的已知1619个类星体中,都有百分比相近的部分为X射线源。Ⅰ型Seyferc星系的发射线H_β与[OⅢ]的等值宽度比R_(EW)同X射线光度L_x强相关,这可作为Ⅰ型Seyfert星系的X射线光度的一个新指标。光学辐射以及2.5GHz以上的高频射电辐射都同X射线辐射相关,说明这三种辐射的区域依次相邻而且机制也相似。色指数U-B和B-V都同X射线辐射不相关,但U-B同B-V弱相关。

The concentration of diphenylhydantoin(DPH)on serum in 107 cases of epileptic patients and 51 cases which both in serum and salivawere measured by Radio-Immuno-Assay technique. The results showed that the effective concentration in serum for controlling the epileptic attack was 13.04 5.96ug/ml (X±SD), 1.34 0.67ug/ml in saliva respectively, which was one-tenth in saliva that compare to the serum, and it was strongly correlation between both of them.It is suggested that the moni tor of DPH content in epileptic...

The concentration of diphenylhydantoin(DPH)on serum in 107 cases of epileptic patients and 51 cases which both in serum and salivawere measured by Radio-Immuno-Assay technique. The results showed that the effective concentration in serum for controlling the epileptic attack was 13.04 5.96ug/ml (X±SD), 1.34 0.67ug/ml in saliva respectively, which was one-tenth in saliva that compare to the serum, and it was strongly correlation between both of them.It is suggested that the moni tor of DPH content in epileptic patient is a useful approach for controlling the attack and effective treatment, and finding side effect in early stage. It isa practicalmethod for measurement of DPH from the saliva and can be accepted by patients generally

本文采用放射免疫分析法,对107例癫痫患者进行了149次血清苯妥英钠(DPH)测定,51例同时进行了血及唾液浓度测定。结果表明,DPH对控制发作的最适血清浓度为13.04±5.96 μg/ml(X±SD),唾液中DPH的有效浓度为1.34±0.67μg/ml,血清浓度约为唾液的10倍,血清浓度与唾液浓度成正相关,测定唾液浓度可代替血清浓度,直接反映游离药物水平,根据DPH浓度可进行药物剂量的调整,指导患者正确用药,对提高疗效有重要意义。

Heart rate variability(HRV)was analyzed in 1 004 normal persons who were subdivided by age into three groups. Using short-term(5 minutes)time and frequency domain measures of HRV,standard deviation of heart rate in beats/min(HRSD),standard deviation of the mean of all 5 minutes segments of normal RR intervals(SDANN),percent of difference between adjacent normal RR intervals that was longer than or equal to 50 ms (PNN50),root mean square successive difference between adjacent normal RR intervals(rMSSD),very low...

Heart rate variability(HRV)was analyzed in 1 004 normal persons who were subdivided by age into three groups. Using short-term(5 minutes)time and frequency domain measures of HRV,standard deviation of heart rate in beats/min(HRSD),standard deviation of the mean of all 5 minutes segments of normal RR intervals(SDANN),percent of difference between adjacent normal RR intervals that was longer than or equal to 50 ms (PNN50),root mean square successive difference between adjacent normal RR intervals(rMSSD),very low frequency(VLF),low frequency(LF),high frequency(HF),total power(TP) and the ratio of low to high (LF/HF)were calculated and correlation between the indices of HRV were analyzed.The results showed that HRSD,SDANN,PNN50,rMSSD,VLF,LF, HF,TP were lower in>45 years group than that in <45 years group (P<0.05 or 0.01);HF was correlated positively with SDANN,PNN50 and rMSSD(r>0.7,P<0. 0001);There was strongly correlation between SDANN,PNN50 and rMSSD(r>0.8,P<0. 0001); There was no significant relation between gender and HRV.Thus,the study suggests that HRV decreases with age; SDANN,PNN50,rMSSD and HF are better indices that reflect vagal nervous activity than the others.

将1004例正常人分三个年龄组进行短程(5min)心率变异性(HRV)分析。时域法的参数为平均心率标准差(HRSD),连续5min节段平均正常RR间期标准差(SDANN),相邻RR间期差的均方根(rMSSD),相邻RR间期差异≥50ms的百分数(PNN_(50));频域法的参数为极低频(VLF)、低频(LF)、高频(HF)成分,总功率(TP)及LF/HF比值。各指标间做相关分析。结果:45岁以上组HRSD、SDANN、rMSSD、PNN_(50)、VLF、LF、HF、TP均低于45岁以下两组(P<0.05或<0.01)。SDANN、rMSSD、PNN_(50)与HF呈高度正相关(r>0.70,P<0.0001),其中以SDANN、PNN_(50)相关更好(r>0.75,P<0.001),SDANN、rMSSD、PNN_(50)间高度相关(r>0.80,P<0.0001)。不同性别HRV各参数相比无显著差异。提示:HRV随年龄的增长而下降,以迷走神经张力下降为主;各指标中以SDANN、rMSSD、PNN_(50)、HF能更好地反映迷走神经张力变化。
