本研究结果发现：(1)任务难度对肩部斜方肌活动有显著影响，即随着任务难度的增强，斜方肌振幅指标增强，但平均功率频率和中位频率基本保持不变；(2)时间压力变化对肩部斜方肌活动有显著影响，但在键盘作业中左、右两侧斜方肌肌肉活动变化强度存在差异；(3)心率指标与肌电信号振幅指标AEMG之间存在相当程度的一致性，能在一定程度上反映心理负荷的变化状况，但在低负荷作业中不够。。。

Low temperature tup impact property of plastic profile shapes and dimension change rate of main profile shapes after heating are two typical technical indexes among 15 testing indexes stipulated in standard GB/T 8814-2004 "Non-plasticized PVC-U for door/window".

PVC 塑料异型材的低温落锤冲击性能与主型材加热后尺寸变化率是GB/T8814—2004《门、窗用未增塑聚氯乙烯型材》标准规定的15项检验指标中具有典型代表意义的2项技术指标，探讨这2项技术指标的影响因素及其相互之间的相关性，为综合提高PVC型材的各项性能，提出了对应的调整措施。

Structural reliability usually is analyzed in Descartes coordinates in which the correlated random variables should be converted to uncorrelated random variables by an orthogonal transformation method.

针对正交空间内，对相关随机变量的可靠指标求解时，需要做正交变换的缺点，研究了广义随机空间内结构可靠指标的计算方法，首次提出了广义随机空间内结构可靠指标计算的随机有限元法。

Methods A total of 60 patients with acute stroke of less than 24 h duration were included in the study. Nutrition risk screening was done in all those patients, with nutritional parameters to evaluate their nutritional status. Nutritional parameters were evaluated at admission and after 14, 28 d after the stroke, respectively. Results We found 15 cases with nutrition risk of 60 patients in admission, and incidence rate of undernutrition is 13.3%.

The analyzing system is tested by experimental data from Shanghai Maglev train, including transverse, longitudinal and vertical acceleration under different uniform motions. The sperling value, integrated comfort value and comfort values in three directions are calculated and compared with the analyzing report of Shanghai Maglev train, which proves the reliability of the sytem.

本文利用此分析系统对上海磁浮列车在不同匀速度行驶时的横、纵、垂向加速度的实验数据进行分析处理，计算了磁浮列车的平稳性指标、综合舒适度指标及各向舒适度指标，并将本分析系统的计算结果与上海磁浮列车分析报告中的计算结果进行比较，从而证实了此分析系统的可靠性。

The method could avoid the unilateralist of only using Dead and injured rate and expenditure rate as the cue to determine the floating rate. Could be on the larger degree to materialize the principle " fair" of the employment injury insurance. And urge the enterprise lower the above index to decease the employment injury rate.

该方法能够避免仅用伤亡指标或支收率指标作为费率浮动依据而产生的评判结果的片面性，能够在更大程度上体现工伤保险"公平"的原则，并促使企业通过降低上述各指标数值以降低自身的工伤保险费率，从而更好的发挥费率机制在工伤预防方面的效用。

A new index system of USAR teams ability is proposed, of which each index is evaluated.

建立了构成救援队能力的指标体系，对指标体系中各个指标逐一做出解释。

Through grey relation estimation matrix, the threat sequencing is transformed into a MADM problem. The algorithm for the weight of each threat criteria is proposed by information entropy to reduce the effect of the extreme numerical value. Applied the grey related projection value, the treat sequencing is carried out from the aspect of vector projection. In addition, the effects of the identification coefficient and the criteria weights on threat sequencing are investigated respectively.

首先通过建立灰色关联判断矩阵将威胁排序转化为多指标决策问题；其次为缩小极端值的影响提出了基于信息熵的威胁指标权重算法；最后从矢量投影角度应用灰色关联投影值进行威胁排序；并分别研究了分辨系数和指标权重对威胁排序的影响。
