当代大学生健康成长的思考与探索——中部地区某高校大学生心理健康状况的调查及思考

目的是考察中部地区某高校大学生心理健康状况,并比较心理健康的性别差异,为针对性开展心理健康教育和思想政治教育提供参考.采用了SCL-90,随机抽取352名中部地区某高校大学生(男生187人,女生165人)进行心理健康情况调查,将结果与全国青年人常模、男女生心理健康状况进行比较.本次调查的结论是该校大学生的心理健康状况总体水平偏低,有近三成的学生有轻度心理问题,不同性别的学生在症状上也有差异.     

A Novel Approach to Vehicle Dynamics using the Theory of a Cosserat Point and its Application to Collision Analyses of Platooning Vehicles

A fully three-dimensional, computationally inexpensive vehicular model is presented. In contrast to traditional rigid body models, the vehicle's sprung mass is modeled as a (nonlinearly) deformable body. The formulation of the equations of motion is based on a continuum theory known as the theory of a Cosserat point. These equations largely preserve the relative simplicity of rigid body dynamics but incorporate deformable features. The ease of computer implementation permits the simultaneous simulation of vehicle and collision dynamics of multiple vehicles and highway objects. In this paper, the theory of a Cosserat point is summarized and its general application to vehicle and collision dynamics is illustrated. A three-dimensional collision algorithm is discussed with emphasis on small closing velocities (negligible residual crush, elastic rebound). The novel model is compared to standard procedures.     

对某汽配厂接触噪声工人90项症状自评量表的调查研究

运用９０项症状自评量表（ＳＣＬ－９０）对汽配厂接触高强度噪声［９５ｄＢ（Ａ）～１００ｄＢ（Ａ）］的工人进行调查发现，接触组工人的人际关系、抑郁、焦虑、敌对、恐怖、偏执、精神病性等因子均与对照有显著性差异，同时也高于正常成人组，提示９０项症状自评量表可以应用于噪声接触工人的心理学研究和早期检测指标的职业流行病学的调查。

高职警察学员心理健康状况与影响因素研究

运用SCL-90对270名高职警察学员的心理健康状况进行总体评价，并与270名同校非警察学员、270名公安学员进行对照研究。结果显示，警察学员的心理问题阳性率为35．56％；心理问题发生率列前的有“人际关系敏感”、“偏执”、“强迫”和“敌对”；同校的警察学员与非警察学员心理健康状况无差异，但优于公安学员。在影响学员心理健康的外在因素中，年级、生活费、父母职业作用较大，而学员个性对心理健康起着一定作用。     

海员心理健康状况评估及其结果分析

采用症状自评量表(SCL-90)对335名随机抽取的现职海员进行了心理问卷调查，结果显示有10．27％的海员存在较严重的心理卫生问题。海员的SCL-90总分及各因子分显著高于全国常模，主要的心理问题为强迫症状、人际关系、抑郁和偏执。     

ANALYSIS OF PSYCHOLOGIC HEALTH STATE AND INFLUENCING FACTORS IN COLLEGE AND SECONDARY SCHOOL STUDENTS IN SHAANXI PROVINCE

It is necessary for educationists to knowstudents psychologic health state in colleges andmiddle schools.In recent years,there are lots of in-vestigations and researches on students psycholog-ic health state in colleges and middle schools.Re-sults have shown thatthe percentage ofcollege andmiddle school students psychologic disorder is be-tween1 0 and30 [1～ 5] .Shaanxi province lies in theNorthwestof China,thus its economics is compara-tively less developed.And also,there are lots ofcolleges…

Geometric-based tyre vertical force estimation and stiffness parameterisation for automotive and unmanned vehicle applications

Advanced empirical, and physical-based tyre models have proven to be accurate for simulating tyre dynamics; however, these tyre models typically require expensive and intensive tyre parameterisation. Recent research into wheeled unmanned ground vehicles requiring vertical force analysis has shown good results using a simple linear spring model for the tyre which demonstrate the continued use for simple tyre models; however, parameterisation of the tyre still remains a challenge when load test equipment is not available. This paper presents a cost-effective tyre vertical stiffness parameterisation procedure using only measured tyre geometry and air pressure for applications where high-fidelity tyre models are unnecessary. Vertical forces calculated through an air volume optimisation approach are used to estimate tyre vertical stiffness. Nine tyres from the literature are compared to evaluate the performance of the vertical force estimation and stiffness parameterisation algorithms. Experimental results on a pair of ATV tyres are also presented.     

毒品依赖者心理健康状况与成瘾行为的相关性

揭示毒品依赖者的心理健康状况及其与成瘾行为的关系。方法　采用症状自评量表和成瘾行为及其相关因素调查表对戒毒所收治的 14 3例毒品依赖者进行调查分析。结果　毒品依赖者的心理健康状况明显较正常人差 ,在SCL -90的因子分中 ,躯体化、抑郁、焦虑和精神病性高分的比例较大 ,而性别、有无职业和是否独居的得分无显著性差异。心理健康状况与成瘾行为相关分析发现 ,用毒量、用毒频率和SCL 90总均分及大部分因子分存在正相关关系 ,而吸毒欲的控制力与SCL 90总均分和大部分因子分呈负相关关系。结论　毒品依赖者的心理健康状况较差 ,心理健康状况与成瘾行为关系密切
