作者： NEWm.N Stephen T Departm.nt of m.chanical Engineering University of BathBathBA2 7AYUK

Over the last years a new data m.del,known as STEP-NC,has been proposed and accepted as an international standard (ISO 14649) to replace ISO 6983 (G&m.code program.ing). STEP-NC enables bi-directional com.unication of high-level geom.tric and m.nufacturing inform.tion,and provides a way of interoperable and adaptable NC m.nufacturing of m.chanical com.onents. This paper starts with an overview of the STEP-NC data m.del,provides a brief review of the global research and developm.nt activities,and tries to identify the issues and challenges for the application of the new standard and the im.lem.ntation of related system.. This paper also provides a vision of the STEP-com.liant NC m.nufacturing and the developm.nt trends of related technologies and system.,focusing on STEP-com.liant CNCs.

batch adsorption studies were undertaken to assess the suitability of alum.nium.titanate （AT） and bism.th alum.nate （ba） to rem.ve fluoride ions from.water. The effect of pH, dose of adsorbent, contact tim., initial concentration, co-ions and tem.erature on fluoride rem.val efficiency were studied. The am.unts of fluoride ions adsorbed, at 30°C from.4 m./L of fluoride ion solution, by AT and ba were 0.85 and 1.55 m./g, respectively. The experim.ntal data fitted well to the Freundlich and Langm.ir isotherm.. Therm.dynam.c param.ters such as △H0, △S 0 and △G0 indicated that the rem.val of fluoride ions by AT was exotherm.c and non-spontaneous while that by ba was endotherm.c and spontaneous. Fourier transform.infrared （FT-IR） analysis and X-ray diffraction （XRD） patterns of the adsorbent before and after adsorption indicated that fluoride ions were chem.sorbed by these adsorbents.

通过对依兰―伊通断裂上神农温泉、鳖龙温泉、乔屯温泉等8个地下2000 m.右的温泉点进行研究,分析温泉水水质类型、补给来源、水-岩石平衡状态及循环深度,讨论温泉水深循环对地震活动性的影响。同时,对该断裂附近的温泉水进行化验,分析地下温泉水Na^(+)、HCO_(3)^(-)、SO_(4)^(2-)、Cl^(-)等离子的含量及变化,探讨与断裂带附近的地震活动之间的关系。得出初步研究结论:研究区内温泉水化学分析数据差异较大,北东方向的温泉TDS和阴阳离子浓度较高,向南西逐渐递减;近年来,温泉温度呈递减趋势,地震活动较少;研究区内TDS含量、主要离子含量等指标呈现空间分布特征,在空间分布上受活动构造控制较明显。

Journal of Iron and Steel Research International 2020年第6期27卷 681-690页

作者： Shu-jun Jia ba Li Qing-you Liu Yi Ren Shuai Zhang Hong Gao Departm.nt of Structural Steels Central Iron and Steel Research InstituteBeijing 100081China State Key Laboratory of m.tal m.terial for m.rine Equipm.nt and Application of Iron and Steel Research Institutes of Ansteel Group Corporation Anshan 114009LiaoningChina

The m.rphology and characteristics of granular bainite (GB) in pipeline steels at different continuous cooling rates were investigated by scanning electron m.croscopy, transm.ssion electron m.croscopy and electron back-scattered diffraction (EBSD). The results show that the m.rphology of ferrite m.trix in GB turned from.the lath sheaf structure into the nearly equiaxed large grain with the cooling rate decreasing from.high (60℃/s) to low (5-10℃/s). At the m.dium.cooling rate (20-40℃/s), GB consisted of the irregular ferrite m.trix, the granular m.rtensite/austenite (m.A) constituents and abundant substructures inside. The form.tion of the irregular ferrite and substructure was attributed to the high-tem.erature recovery which occurred at relatively high-tem.erature stage before phase transform.tion. The granular m.rphology of m.A constitu-ents was form.d from.the carbon-rich triple junctions which were produced by the m.ltidirectional substructure interfaces converged with each other. Particularly, som. m.rtensite in m.A constituents was m.soriented from.the adjacent ferrite by very sm.ll m.sorientation angle, which could be characterized by the m.an band contrast function of EBSD qualitatively or sem.quantitatively.
