Objective To investigate the current status of rumination and professional grief among hospice nurses, and to explore the mediating effect of death attitude between the two. Methods A total of 323 nurses in hospitals with hospice services and hospice wards in Hangzhou City were surveyed from April to July 2024 by convenience sampling method. They were investigated with general information questionnaire, Event Related Rumination Inventory, Death Attitude Profile-Revised, and Grief State Scale for Nurses by convenience sampling method. The structural equation model was used to analyze the mediating effect of death attitude between rumination and professional grief among hospice nurses. Results A total of 331 questionnaires were collected, among which 8 invalid questionnaires were deleted, and 323 valid questionnaires were retrieved, with the valid questionnaire recovery rate of 97.58%. The score of intrusive rumination dimension for hospice nurses was 13.34 (7.00, 20.00), and the score of deliberate rumination dimension was 16.92(11.00, 24.00). The negative attitude towards death scored 38.35 (29.00, 48.00) .while the positive attitude towards death scored 62.88(49.00, 78.00). The total score of Grief State Scale for Nurses was 47.05(40.00, 53.00). Hospice nurses' intrusive rumination was positively correlated with negative attitudes toward death, professional grief, and negatively correlated with positive attitudes toward death (all P<0.05);deliberate rumination was negatively correlated with negative attitudes toward death, professional grief, and positively correlated with positive attitudes toward death (all P<0.05). Negative death attitudes and positive death attitudes partially mediated between intrusive rumination and professional grief, with mediation effects of 0.053 and 0.037, accounting for 12.70% and 9.25% of the total effect. Negative death attitudes and positive death attitudes similarly partially mediated between deliberate rumination and professional g

近年来,宽频、大吨位的横波可控震源在油气勘探中的应用日益广泛,横波地震在气云区成像和地质构造解释等方面展现了显著优势。横波对各向异性尤为敏感,然而即使在较为简单的VTI(具有垂直对称轴的横向各向同性)介质中,qSV波的传播特征也相当复杂,例如在较强各向异性条件下(各向异性参数σ> 0.3),qSV-qSV波的时距曲线在中-远偏移距(x/z=1.7~2.0)出现“横波三重波”(shear wave triplication)现象,导致近偏移距与中-远偏移距的时距曲线特征差异显著。现有的qSV-qSV波时距曲线近似方程通常基于小偏移距(x/z=0)处的一阶近似,因而在中-远偏移距范围内精度较低。针对这一问题,本文从qSV波相、群速度表示的精确时距曲线方程出发,结合相、群速度的二阶近似式,以及在x/z=2位置,相、群速度以及相、群角相等的特征,推导出了一种包含改进收敛因子的高精度的时距曲线方程。对比分析表明,在较强各向异性条件下,与现有的近似方程相比,新方程能够在远偏移距更好地收敛至实际时距曲线。本研究为地震横波资料处理提供了更加精确的非双曲时距曲线近似方程,有助于在地震资料处理中保留更多的远偏移距信息,对横波速度和各向异性参数的建模、横波反演等提供了重要的理论支撑。
