论非典型鉴定意见的法律效力——“鉴定咨询意见”、“鉴定检验报告”、“技术证据审核意见”的证据能力问题亟需依法统一认识

“两种意见”和“两种检验报告”的性质和作用问题,在司法鉴定和司法活动中是经常引起争议的理论和实践问题。本文针对当前的争议．对每个问题提出了自己的观点和解决争议的主张。认为“鉴定专家咨询委员会”出具的“鉴定咨询意见”不是鉴定意见．不能作为定案的根据,只能作为侦查、审查起诉、审判的参考。并论证了其中的多方面原因;主张“鉴定检验报告”应当区分法定与法外两种性质,分别属于法定鉴定意见证据和仅供审判部门参考的非法定证据．并提出了对两种不同性质“检验报告”的使用评断原则;认为人民检察院、人民法院的“科技证据审核活动”．属于司法机关对鉴定意见的内部咨询活动,审查的范围仅限于四个方面．技审人员和机构无权对司法鉴定意见进行否定或肯定．只能对四方面的问题提出“审查建议”,“技术审查意见”只能作为检察、审判机关审查起诉和审判的内部参考．不能栽入起诉书和裁判文书。     

高铁沿线突发事件中车站滞留旅客处置研究

高铁沿线突发事件导致的大规模列车晚点或停运会进一步传导引发车站旅客滞留。为建设高铁品牌,回应旅客权利诉求,避免车站衍生事故的发生,基于高铁沿线突发事件导致车站旅客滞留具有事件传导性、危机叠加性、处置迟滞性的特点,高铁相关部门需落实滞留旅客处置工作预案,健全安全综合治理的长效机制;推动各单位面对突发事件的应急联动,拓宽各路局间信息精准共享渠道;优化滞留旅客服务补救流程,制定统一的滞留旅客补偿标准,以期为高铁相关部门依法、高效、妥善处置车站滞留旅客事件提供应急策略,提高旅客对高铁客运服务的满意度。

Analyzing the uncertainty of simulation results in accident reconstruction with Response Surface Methodology

This paper is focused on the uncertainty of simulation results in accident reconstruction. The Upper and Lower Bound Method (ULM) and the Finite Difference Method (FDM), which can be easily applied in this field, are introduced firstly; the Response Surface Methodology (RSM) is then introduced into this field as an alternative methodology. In RSM, a sample set is firstly generated via uniform design; secondly, experiments are conducted according to the sample set with the help of simulation methods; thirdly, a response surface model is determined through regression analysis; finally, the uncertainty of simulation results can be analyzed using a combination of the response surface model and existing uncertainty analysis methods. It is later discussed in detail how to generate a sample set, how to calculate the range of simulation results and how to analyze the parameter sensitivity in RSM. Finally, the feasibility of RSM is validated by five cases. Moreover, the applicability of RSM, ULM and FDM in analyzing the uncertainty of simulation results is studied; the phenomena that ULM and FDM can hardly work while RSM can is found in the latter two cases. After an analysis of these five cases and the number of simulation runs required for each method, both advantages and disadvantages of these uncertainty analysis methods are indicated.     

Response surface methodology and improved interval analysis method-For analyzing uncertainty in accident reconstruction

Methods used to calculate intervals of accident reconstruction results are research hotspot in the word. The response surface methodology-interval analysis method (RSM-IAM) is a useful method for analyzing uncertainty of simulation results in this field, but there are two problems in this method because of the interval extension problem and inaccurate response surface models. In order to tackle these two problems, based on subinterval analysis thought and response surface methodology, an improved interval analysis method (RSM-IIAM) is proposed. In RSM-IIAM, the stepwise regression technique is used to obtain a reasonable response surface mode of the simulation model; and then, intervals of uncertain parameters are divided into several subintervals; after that, intervals of simulation results in accident reconstruction are calculated according to these subintervals. Finally, four numerical cases were given. Results showed that the RSM-IIAM is simple and high accuracy, which will be useful in analyzing uncertainty of simulation results in accident reconstruction.     

螺旋CT三维重建在肋骨骨折法医临床鉴定中的应用

目的探讨螺旋CT三维重建评价肋骨骨折在法医临床中应用价值。方法收集肋骨骨折35例,分别采用X线摄片、CT扫描及螺旋CT三维重建检查。结论35例检查都取得清晰的立体图像,且可以消除周围组织结构,单独观察肋骨骨折情况。结果:螺旋CT三维重建在肋骨骨折的诊断、法医临床学中有较高的价值。     

不同年龄下颌骨应力分布与骨折发病率的关系

目的分析不同年龄的下颌骨正中受力时,下颌骨三维有限元分布的差异。方法选用儿童、中年和老年的下颌骨,采用螺旋CT扫描,MIMICS软件建模,HYPERMESH软件划分单元,ANSYS进行三维有限元应力分布分析。结果三种年龄下颌骨最大的平均综合应力均出现在下颌角;中年的下颌颈有应力的分布,但老年和儿童的下颌颈几乎没有应力的分布。结论下颌骨应力的分布与骨折的发病率相关,不同年龄下颌骨应力的分布与骨折的高发年龄相关。
