研究了氮含量为0.83%的高氮奥氏体不锈钢在经冷压缩处理后对拉伸性能的影响和微观组织的演变。对不同冷压缩率的样品进行了准静态拉伸实验。结果表明:在整个冷压缩率范围内,该材料具有良好的强度和延展性。高氮奥氏体不锈钢受冷压缩影响很大,随着冷压缩率的增加,强度急剧增加,塑性大幅下降,主要是因为冷压缩后微观组织的演变。高氮奥氏体不锈钢经85%冷压缩处理后,屈服强度较固溶态提高约3倍,达到1507 MPa,抗拉强度较固溶态提高了约2倍,达到1659 MPa。

作者： Qin HUANG mingxu zhang Zulin WANG Xuanwei zhang School of Electronic and Information Engineering Beihang University Collaborative Innovation Center of Geospatial Technology

This paper focuses on the advanced Forward Error Correction(FEC) based on LowDensity Parity-Check(LDPC) codes for remote control and data transmission of Aeronautic and Astronautic Vehicles(AAV). It shows that the nontransparent LDPC codes with odd row weights are able to resist phase inversion with a small computational overhead. To the best of our knowledge, it is the first time to use FEC to resist phase inversion. Then, a high hardware-efficient FEC design for AAV, which is capable of correcting random errors as well as phase inversion, is proposed based on circulant decomposition with circulant size of 2s. Such a(4096, 2048) LDPC code has been adopted in a data transmission system due to its excellent error performance and hardware efficiency.

作者：徐子芳 zhang mingxu HU Wenpei School of Material Science and Engineering Anhui University of Science and Technology

Super plasticizer was synthesized by using coal coking by product washing oil and industrial naphthalene. The results show that sulfonationt time （2.5 h）, sulfonation temperature （160 ℃） and condensation time （5.0 h） are key factors. Adding oxidizing agent MO in the course of synthesis can decrease the emission of SO2 in exhaust （20%）. Compared with NF, NF-30 have some advantages in lower cost, high water reducing rate （19.7%） and optimum early strengths. Moreover, TGA-DTA and SEM analysis were adopted to research the NF-30 modified concrete on hydyation mechanism. The analysis show that, compared with NF, there are a large number of hydration products such as Ca （OH）2, C-S-H, AFt etc of NF-30, the structure of NF-30 is dense and the performance is good.

中熵合金具有多种优异性,同时具有高强度和延展性。冷轧变形是提高中熵合金力学性能的一种即经济又有效的方法。对CoCrNi中熵合金进行室温不同变形量(25%,37.5%,50%,62.5%,75%)的冷轧,通过X射线衍射分析、显微组织分析和拉伸试验研究了室温下不同变形量对合金显微组织和力学性能的影响。结果表明:在室温不同变形量冷轧下CoCrNi中熵合金的组织仍为单一的FCC结构。CoCrNi中熵合金室温抗拉强度较低,随着变形量的增加,抗拉强度显著提升,但延展性相比铸态变差。
