The systolic time intervals (STI) in 210 normal subjects (110 males & 100 females) were measured on the simultaneously recorded electrocardiogram, carotid pulse tracing and phonocardiogram. The results are as follows: 1. The intervals of Q-S_2 (total electromechanical systole), LVET (left ventricular ejection time) and PEP (pre-ejecfion period) are remarkably inversely related to heart rate; ICT (isovolumic contraction time) and Q-S_1 (electromechanical delay) are slightly correlated with heart rate; PEP/LVET...

The systolic time intervals (STI) in 210 normal subjects (110 males & 100 females) were measured on the simultaneously recorded electrocardiogram, carotid pulse tracing and phonocardiogram. The results are as follows: 1. The intervals of Q-S_2 (total electromechanical systole), LVET (left ventricular ejection time) and PEP (pre-ejecfion period) are remarkably inversely related to heart rate; ICT (isovolumic contraction time) and Q-S_1 (electromechanical delay) are slightly correlated with heart rate; PEP/LVET and ICT/LVET ratios do not correlate with heart rate. 2. There are significant sex differences in the parameters of Q-S_2, PEP, LVET, Q-S_1 and PEP/LVET, while ICT and ICT/LVET do not show any sex difference. 3. Q-S_2, LVET, ICT and ICT/LVET are dependent on ages. If STI are corrected with heart rate, the influence of ages may be neglected.For the purpose of correcting STI with heart rate and sex, the linear regression equa tions of STI with heart rates in male and female groups were calculated respectively. Substitute different heart rates into the equations, the values obtained will represent the normal values of STI under corresponding heart rates, the upper and lower limits being obtained with±1. 645 times standard error of estimate. Thus we constructed a table of normal values of PEP, LVET and PEP/LVET with their upper and lower limits.For practical use it is benificial to propose a rough range of normal values under moderate heart rate. According to our study, the normal values of ICT, Q-S_1, PEP, LVET, Q-S_2 are 25-45 ms, 60-80 ms, 80-110 ms, 260-340 ms and 340-440 ms respectively. ICT/LVET ratio is 0.09-0.15. PEP/LVET ratio is 0.29-0.34 in male and 0.30-0.35 in female. But it needs to correct the values with heart rate when the latter is too fast or too slow. By estimating the function of the left ventricle, one ought to keep in mind the upper limits of ICT, Q-S_1, PEP, ICT/LVET and PEP/LVET and the lower limits of LVET and Q-S_2. We considered it abnormal if the values measured are above or below these limits. Actually the more they exceed the normal ranges and the more abnormal indices appear, the greater clinical significance they have.

用同步快速记录ECG,PCG和CPT的方法,测定了210名正常人(男110名,女100名)的心脏收缩时间间期(STI),并分析其与心率、性别和年龄的相关。结果如下:1.Q-S_2,LVET,PEP与心率呈负相关非常显著,ICT和Q-S_1与心率相关较小,这两个指标不必与心率相校正。2.Q-S_2,LVET,PEP,Q_S_1与PEP/LVET的性别差异显著,而ICT/LVET和ICT不存在性别差异。3.Q-S_2,LVET,ICT与ICT/LVET存在着年龄的影响,PEP,Q-S_1与PEP/LVET不存在年龄差异,与心率相校正后,年龄对STI的影响可以不予考虑. 为了与心率、性别相校正,分别求出了男、女组与心率有关的直线回归方程式,以不同的心率代入,所得的数值再加、减1.645倍标准估计误差作为正常值的上限或下限,并据此制作了PEP,LVET,PEP/LVET的正常数值表。 为了在实际工作中便于记忆和掌握,在中等心率时制定一个大致的正常范围是有用的。我们提出ICT,Q-S_1,PEP,LVET,Q-S_2的正常值分别为25—45ms,60—80ms,80-110ms,260—340ms和340—440ms,...

The influence of different cooling rate on thermoelastic martensitic tarnsformation of Cu-Al-Ni alloy has been studied by means of resistance method and X-ray diffraction method in this paper.

The ratio between martensite and parent phase also changes with different cooling ra(?)e. There is a maximum ratio for a suitable cooling rate, and if the cooling rate is too fast or too slow it will decrease.

Fingerprints, which has been regarded as "the first material evidence"for a long time are of astonishing stability, characteristics.Everyone has different fingerprints, which never change in his life, and can mark on anything if one touch it.Because of the characteristics mentioned above, fingerprints are still an important material evidence in modern criminal-case solving and detecting.However, the conventional method of comparing fingerprints is too slow to meet the needs of the modern society.In order to satisfy the need,as application base on ALTOS-ACS system has been developed, ALTOS-ACS system is a 16 bits digital microcomputer-of 68000 series.This is named fingerprints management system which is as efficient digital system for storing and managing fingerprints. In this system, hierarchical model and model block structure are adopted.It has been proved that,this system is quick in query,low in duplication and high in precision.It has a great practical value in analysing the results and vague processing.This paper mainly introduces the function of the system, the method of analyzing fingerprints codes,and the entire logical design of composing System.The determination of the data structure,command programme system and vague processing on the spot and query etc.,are also introduced here.

指纹,具有惊人的稳定性、特殊性和反映性,很早就被尊为“物证之首”。由于指纹有各人不同、终生不变、触物留痕的特点,在现代侦察破案中,仍具有重要的证据作用。在现行的人工对比指纹,已远远不能满足现代化社会的需要。为了实现用户需要,我们在ACS—68000型高档微机上研制开发了应用库——指纹管理系统。指纹库是对指纹进行有效存贮管理的数据系统,它采用分层模型、模块结构。本系统经使用验证,具有检索速度快、重复率低、准确等特点,对样本或分析结果进行模糊处理,均有很好的实用价值。 本文主要介绍系统功能、指纹编码分析方法、系统组成总体逻辑设计、数据结构的确定、命令程序系统、现场指纹模糊处理与查询等技术与实现。
