Furthermore , a scheme is developed by which a few single - parameter based random perturbation analyses are combined to produce the results for a multi - parameter random purturbation analysis 建立了由单参数变异性摄动分析组合出多参数变异性分析结果的算法。
The software is based on c programming language . it includes the body weight measurement module , fat measurement module , hrv analysis module and lcd display module , etc 软件设计以c语言为平台，进行模块化程序设计，设计了体重测量、脂肪测量、心率变异性分析和液晶显示等软件模块。
The experimental instrument has been developed in order to validate our ideas on physical fitness measurement . it is incorporated with weighting , measuring body composition and analyzing hrv 为了验证上述思想，研制了实验样机，它将称重、人体成分测量和心率变异性分析融为一体。
It is found that there exists significant correlation between heart rate and physical fitness through the study of physiology of physical fitness . so hrv is also selected as a way to evaluate physical fitness 在体能生理学研究的基础上，我们发现人的心率和体能有较显著的相关性，为此我们提出把心率变异性分析也作为评测体能的有效途径。
Aiming at the relatively lagging test situation in china , in this paper it carries a full - scale research on the sub - grade and pavement construction parameters based on the luo - san highway in he - nan , and it analyses the variabilities of them 针对国内检测相对落后的状况，本文以河南洛三高速公路为依托，全面调查了路基路面的施工参数，结合试验段进行施工质量的变异性分析。
As the traditional method of physical fitness measurement is n ' t easy to carry out and popularize , this paper is to research the new static method of physical fitness measurement based on body composition measurement and hrv ( heart rate variability ) analysis 本课题针对目前人体体能测量的传统方法实施和推广的困难，提出了一种以人体成分测量和心率变异性分析为基础的静态体能测量的新方法。
From the results of the experiments on athletes and ordinary people , we can see that the unproved method measuring body composition is of feasibility and it is of validity to measure physical fitness by measuring body composition and analyzing heart rate variability 经自制样机对运动员和普通人人体实验验证，证实了人体成分测量改进方法的可行性，人体成分测量合并心率变异性分析对人体体能测量的有效性，看到了此方法的良好发展前景。
The antigenic and genetic variability of porcine reproductive and respirators syndrome virus ( prrsv ) isolates in china were studied by immunofluoresent monolayer assays ( 1fma ) and restriction fragment length polymorphism ( rflp ) of reverse transcription ( rt ) and polymerases chain reaction ( pcr ) amplified - prrsvorfs fragments among 8 chinese isolates 本研究通过对猪繁殖与呼吸综合征病毒( prrsv )国内分离毒株的gp3 、 gp5和n蛋白的抗原性比较及其orf5和orf7遗传变异性分析，系统研究了国内分离毒株的抗原特性和遗传学差异。
