To address the low conductivity and easy agglomeration of transition metal sulfide nanoparticles,FeCoS_(4) nanoparticles embedded in S-doped hollow carbon(FeCoS_(4)@S-HC)composites were successfully fabricated through a combination of hydrothermal processes and sulfidation *** unique bowlshaped FeCoS_(4)/S-HC composites exhibit excellent structural stability with a high specific surface area of 303.7 m^(2)·g^(-1) and a pore volume of 0.93 cm^(3)·g^(-1).When applied as anode material for lithium-ion batteries,the FeCoS_(4)@S-HC anode exhibits efficient lithium storage with high reversible specific capacity(970.2 mA·h·g^(-1) at 100 mA·g^(-1))and enhanced cycling stability(574 mA·h·g^(-1) at 0.2 A·g^(-1) after 350 cycles,a capacity retention of 84%).The excellent lithium storage is attributed to the fact that the bimetallic FeCoS_(4) nanoparticles with abundant active sites can accelerate the electrochemical reaction kinetics,and the bowl-shaped S-HC structure can provide a stable mechanical structure to suppress volume expansion.

To solve the volume expansion and poor electrical conductivity of germanium-based anode materials,Ge/rGO/CNTs nanocomposites with three-dimensional network structure are fabricated through the dispersion of polyethylene-polypropylene glycol(F127)and reduction of *** interesting phenomenon is discovered that F127 can break GeO_(2)polycrystalline microparticles into 100 nm nanoparticles by only physical interaction,which promotes the uniform dispersion of GeO_(2)in a carbon network structure composed of graphene(rGO)and carbon nanotubes(CNTs).As evaluated as anode material of Lithium-ion batteries,Ge/rGO/CNTs nanocomposites exhibit excellent lithium storage *** initial specific capacity is high to 1549.7 mAh/g at 0.2 A/g,and the reversible capacity still retains972.4 mAh/g after 100 *** improved lithium storage performance is attributed to that Ge nanoparticles can effectively slow down the volume expansion during charge and discharge processes,and threedimensional carbon networks can improve electrical conductivity and accelerate lithium-ion transfer of anode materials.

Background Pressure therapy improves hypertrophic scar healing, but the mechanisms for this process are not well understood. We sought to investigate the differential expression of matrix metalloproteinases （Mmps） and collagen in post- traumatic hypertrophic scar tissue with mechanical pressure and delineate the molecular mechanisms of pressure therapy for hypertrophic scars. Methods Fibroblast lines of normal skin and scar tissue were established and a mechanical pressure system was devised to simulate pressure therapy. Reverse transcription-polymerase chain reaction （RT-PCR） and Western blotting assays were used to compare differences in the mRNA and protein expression of Mmps and collagen in scar fibroblasts before and after pressure therapy. Results The expression differed between the hypertrophic scar cell line and the normal cell line. RT-PCR assays showed that Collagen I, highly expressed in the hypertrophic scar cell line, decreased significantly after pressure therapy. Mmp2, Mmp9, and Mmp12 expression in the hypertrophic scar tissue increased significantly after pressure therapy （P 〈0.05）. Western blotting assays further revealed that Mmp9 and Mmp12 expression increased significantly in the hypertrophic scar tissue after pressure therapy （P 〈0.05） but not Mmp2 expression （P 〉0.05）. Conclusion Mechanical pressure induces degradation of Collagen I in hypertrophic scar tissue by affecting the expression of Mmp9 and Mmp12.

针对单次扫描角度不同引起的夹杂检测误差较大、稳定性低等问题,提出了一种低密度粉末材料的多角度数字化X射线摄影(DR)扫描夹杂检测方法。首先对被测对象进行多角度DR检测;然后采用尺度不变特征变换(SIFT)特征匹配的方法寻找不同角度下夹杂的图像,自动选取不同角度下夹杂尺寸的最大值作为近似值;最后建立不同角度下夹杂面积和旋转角度的关系,并预测出夹杂的最大面积和旋转角度。实验结果表明,所提方法解决了计算机断层扫描(CT)效率低的问题,相比单次扫描检测方法,进一步提高了检测的准确性和稳定性,并且较小旋转角度下的预测具有较高置信度,能够满足实际生产检测需求。

使用二维CT图像与设计模型通过比对进行制造误差分析时,必须知道CT图像在设计模型中的位置,而位置的确定往往需要在工件上找到一个和设计模型相匹配的基准位置,并对该位置进行精加工,这增加了工件加工的周期和制造成本。针对该问题,本文提出一种自动搜索CT图像的设计模型来完成工件制造误差检测的方法。该方法首先提取CT图像的边缘,然后把点云设计模型分层切片;接着通过Hu矩匹配,ICP配准自动搜索到与CT图像相匹配的点云切片;最终根据两者的配准结果,计算工件误差分布,完成工件的制造误差检测。为验证该方法的可行性,采用已知尺寸的标准工件进行检测,结果表明,检测误差集中分布在0~0.25 pixel之间,具有较高的检测精度。并对两个实际工件进行检测,验证了该方法的适用性。本文在无须确定工件基准位置的情况下,使用工件二维CT图像与设计模型完成工件的制造误差计算、分析与显示,具有很高的实用意义。

针对传统的铸件缺陷检测不能对缺陷进行分类分级等问题,提出了一种基于Mask R-CNN的铸件X射线DR图像缺陷检测算法。首先对原始图像进行预处理,采用引导滤波进行图像平滑,平滑图像与原图像进行差分得到差分图像,将差分图像与平滑图像相加运算使图像增强,再利用Labelme进行图像标注,形成训练数据集。送入Mask R-CNN深度学习网络,通过特征提取网络生成建议区域,分类、回归网络生成边界框和掩码,经多次参数调节后得到训练网络模型,最后测试数据集。实验数据结果表明,气泡1~5级的检测率分别为:66.7%,71.4%,77.4%,88.9%,87.5%;疏松1~5级检测率为:62.5%,72.2%,77.1%,83.3%,81.1%。检测结果证明应用Mask R-CNN结合引导滤波增强方法的缺陷检测方法可以较好的实现对铸件X射线DR图像的缺陷检测的分级分类,为工业铸件缺陷检测提供了应用深度学习方法的解决方案。
