The thermal insulation performance of riser is very important to the shrinkage porosity and solidification structure of ingot,but it is difficult to significantly improve due to the limit of thermal conductivity of riser material.A new type of hollow insulation riser was proposed based on the low thermal conductivity of air,which aims to improve the thermal insulation performance of riser.A 14.5-t steel ingot was prepared using the hollow insulation riser,and the casting temperature was 1500°*** temperature evolution of the external surface of mold during solidification was measured using an infrared temperature instrument.A numerical model was established to simulate the porosity and solidification structure of *** reliability of numerical simulation was verified by comparing simulation and experimental *** show that the insulation performance of the riser can be significantly improved through application of the hollow insulation *** with solid insulation sleeve,the shrinkage cavity depth was decreased and the position of porosity was raised when hollow insulation riser was applied.

Objective: To investigate the anti-inflammatory properties of methanolic extract of Clausena excavata in lipopolysaccharide(LPS)-activated macrophages(J774 A.1) and the effect on skin wound in a rat model through determining cytokine levels and gene expressions. Methods: The effects of methanolic extract of Clausena excavata on in vitro viability and TNF-α, IL-6, IL-10, and nitric oxide release by LPS-activated J774 A.1 cells were determined. In addition, relative expressions of BAX, BCL-2 and COX-2 genes were examined in healed wounds of rats. Results: The methanolic extract of Clausena excavata was not toxic to J774 A.1 cells at the highest dose of 400 μg/m L. It decreased levels of TNF-α and IL-6, while increasing IL-10 level in LPSactivated J774 A.1 cells and in the healed wounds of rats. The methanolic extract of Clausena excavata also inhibited nitric oxide production in LPS-activated J774 A.1 cells. The BAX and COX-2 genes were downregulated while the BCL-2 gene was upregulated in the healed wound of rats. Conclusions: The methanolic extract of Clausena excavata promotes wound healing via its anti-inflammatory and anti-apoptotic activities.

功能改进，模型率定，模型预报的验证以及其结果分析是应用概念水文模型所需要的几个主要部分。考虑到物理模型应用上的复杂，概念模型所代表的主要过程便是对客观现实的高度简化，但因此也带来了大量显著的不确定因素。鉴于此种情况本文将人工神经网络算法同新安江模型相耦合以提高模型预报的精度。计算中使用了近期观测资料以及模型中径流／流量预报产生的误差／残差。本耦合模型的工作原理为：通过人工神经网络来预报模型的误差来提高用新观测资料得到的流量预报精度。从本文研究结果来看，结合人工神经网络算法的新安江模型的预报结果同只单独使用新安江模型时相比，在精度上有相当大的提高。对模型预报残差进一步分析可知，残差的时间序列并不服从正态分布，而是呈现出了逆高斯分布。同样，在误差/残差结构中存在着非常明显的固定模式。

Availability of affordable and widely applicable interatomic potentials is the key needed to unlock the riches of modern materials *** neural network-based approaches for generating potentials are promising;however,neural network training requires large amounts of data,sampled adequately from an often unknown potential energy *** we propose a selfconsistent approach that is based on crystal structure prediction formalism and is guided by unsupervised data analysis,to construct an accurate,inexpensive,and transferable artificial neural network *** this approach,we construct an interatomic potential for carbon and demonstrate its ability to reproduce first principles results on elastic and vibrational properties for diamond,graphite,and graphene,as well as energy ordering and structural properties of a wide range of crystalline and amorphous phases.
