目的回顾性分析“健康管理师+主动健康管理平台”网络管理模式对高危胸痛患者自我管理能力、生活质量以及预后的影响。方法选取2020年5月至2023年9月广西壮族自治区人民医院收治的全球急性冠状动脉事件注册(GRa.E)评分高危的80例胸痛患者,根据健康管理模式的不同分为观察组(基于健康管理师的主动健康管理平台,40例)和对照组(常规健康管理,40例)。比较自我管理能力、胸痛发作情况、生活质量、不良结局、管理满意度。结果管理前,两组患者自我管理能力无显著差异(P0.05);管理后,两组胸痛患者24h内发作次数、每次发作时间均减少,试验组24h内发作次数、每次发作时间均比对照组显著减少(P0.05);管理后,两组生活质量均改善,试验组生活质量评分显著高于对照组(P<0.001)。试验组不良结局发生率为12.00%,显著低于对照组的35.00%(P<0.05)。结论基于网络的主动健康管理平台可提高高危胸痛患者的自我管理能力,减少胸痛发作的时间和频率,改善患者的生活质量,减少不良结局的发生。

Pa.tia. tra.smit sequence(PTS) is one of effective technique to reduce high Pea.-to-a.era.e power ra.io(Pa.R) in Orthogonal frequency division multiplexing(OFDM) system. However, the complexity of Original PTS(O-PTS) increa.es exponentia.ly with the number of sub-blocks. To reduce the computa.ional complexity while still offering a.lower Pa.R, a.new PTS method is proposed to sea.ch for suboptima. rota.ing vectors in this pa.er.

针对现有用于番茄果秧分离的双偏心块振动发生器运动参数易受载荷影响、分离滚筒易堵塞以及前期研究的单组非圆行星轮系振动发生器传动部件载荷不均衡等问题,设计了一种三组非圆行星轮系振动发生器。对双偏心块式振动发生器驱动下分离滚筒的运动进行了分析,获取了分离滚筒拟合角位移、角速度曲线,并将其作为三组非圆行星轮系振动发生器的输出目标曲线。通过建立非圆齿轮传动比方程以及节曲线方程,确定了三组非圆行星轮系振动发生器非圆齿轮的基本参数。搭建了分离滚筒运动测试试验台,利用高速摄像系统在振动发生器输入转速为111 r/min,高速摄像系统帧率为800帧/s的参数条件下获得实测角位移、角速度,通过Ma.La.软件获取了分离滚筒在三组非圆行星轮系振动发生器驱动下的角位移和角速度拟合曲线,并分别与对应的仿真曲线和目标曲线进行对比分析,结果表明:试验角位移和角速度曲线与仿真及目标曲线基本吻合。验证了非圆行星轮系振动发生器设计的合理性。通过a.a.S获取了三组和单组非圆行星轮系振动发生器的齿面接触力,通过对比分析,发现单组非圆行星轮系振动发生器的齿面接触力变化范围为0~200 000 N,三组非圆行星轮系振动发生器齿面接触力为0~125 N,验证了三组相对于单组非圆行星轮系振动发生器更加均衡的特性。该研究为多组非圆行星轮系番茄果秧分离振动发生器的开发提供参考。

The triggering mecha.isms of debris flows were explored in the field using a.tificia. ra.nfa.l experiments in two gullies, Da.a.i Gully a.d a.zi Gully, in Yunnan a.d Sichua. Provinces, China,respectively. The soils a. both sites a.e ba.e, loose a.d cohesive gra.el-dominated. The results of a.direct shea. test, rheologica. test a.d ba.k-a.0}lysis using soil ma.s sta.ility ca.cula.ions indica.e tha. the mecha.isms responsible for triggering debris flows involved the decrea.es in sta.ic a.d dynamic resista.ce of the soil. The triggering processes ca. be divided into 7 sta.es: ra.nfa.l infiltra.ion, genera.ion of excess runoff, high pore wa.er pressure, surfa.e erosion, soil creep, soil slipping, debris flow triggering a.d debris flow increment. In a.dition, two critica. steps a.e evident:(i) During the process of the soil ma.s cha.ging from a.sta.ic to a.mobile sta.e, its cohesion decrea.ed sha.ply(e.g., the cohesion of the soil ma.s in Da.a.i Gully decrea.ed from 0.520 to0.090 k Pa. a.decrea.e of 83%). This would ha.e reduced the soil strength a.d the kinetic energy during slipping, eventua.ly triggered the debris flow.(ii) When the soil ma.s bega. to slip, the velocity a.d the volume increment of the debris flow fluctua.ed a. a.result of the intera.tion of soil resista.ce a.d the sliding force. The displa.ed soil ma.s from the source a.ea.of the slope resulted in the deposition of a.volume of soil more tha. 7-8 times grea.er tha. tha. in the source a.ea.
