不均匀分布

ISO834 and parametric equation approach are lack of pertinence. The results may be too conservative. The temperature obtained by zone model is low, so that it is not suitable for the performance-based fire protection design on this structure. Field model considers the heterogeneity of environmental temperature, and its result is close to the real fire, so that it is commended to the performance-based fire protection design on steel staggered-truss structure.

国际标准升温曲线和参数化室内升温曲线不考虑火源功率、建筑通风口等因素，缺乏针对性，分析结果偏于保守；区域模型所得温度偏低，不宜用于交错桁架结构的性能化抗火设计；场模型考虑了火源功率及环境温度分布的不均匀性，和实际火灾较接近，计算结果相对较为准确，可用于结构的性能化防火设计。

By analyzing the problem of hydrological 3D spatial dispersion in 3D finite differential numeric simulation of porous groundwater flow, as well as discontinuous spatial distribution and asymmetric thickness of porous aquiferous strata and partitive groundwater stratum, the paper presents the GIS-based technique of 3D spatial dispersion of porous aquiferous stratum system. Besides, the paper puts forward the 3D spatial dispersion method of irregular hexahedral unit based on GIS to guarantee to the greatest degree the uniqueness of the stratum types among the dispersed units and improve the precision of 3D spatial dispersion.

实验结果证明，蜗壳的实际流动情况同理论设计有着相当大的不同，蜗壳的不对称结构导致了其流动周向参数分布不均匀，并且影响了叶轮扩压器内的流动，导致整机工作性能下降。

The aseismic control for pile-foundation bridges considering soil-structure-interaction was studied. There are two problems were solved:(1) The coefficient matrix is singularity because the elements of rotational degree in mass matrix equal to zero due to the flexiblity of the pier.(2) The iteration of control gain was not convergent because the dumped mass of the beam is very large comparing with that of the pier.

为将Smith[162]方法用于桥梁结构，本文解决了如下两个问题：(1)以弯曲变形为主的桥梁结构，其质量矩阵中相应于转动自由度的元素数值为零，由此导致等效固基模型中的系数矩阵奇异；(2)桥梁结构堆聚到顶部节点的梁体质量很大，由于质量分布不均匀导致控制增益的迭代计算不收敛。

The lab findings show, the no-blemish copper deposition can be realized through selective copper deposition in trench. In the process of electro-plating, via and crevice come into being due to the misproportion of the current density inside and outside the trench.

在电镀的条件下，凹槽电镀铜产生空洞和缝隙原因是凹槽内外电流密度分布不均匀，使凹槽内外镀层生长速度不一致，最终导致空洞和缝隙形成。
