尿素解吸废液及甲醇残液联合处理工艺的应用

安阳化学工业集团公司(以下简称安化集团)现有2套200 kt/a尿素装置及1套60 kt/a甲醇装置.尿素及甲醇装置在生产过程中会产生大量的尿素解吸废液和甲醇残液,废液中的氨氮(NH3-N)含量和化学需氧量(CODCr)较高,给该公司废水的达标排放带来很大压力.     

溶胶-凝胶法制备Li（MoO4）2：Eu及表征

用溶胶-凝胶法制备了平均粒径为2～3μm的小颗粒、高亮度的Li（2-x）（MoO4）2：Eu系列钼酸盐红色荧光体。用XRD、SEM、粒度分析和分子荧光光度计对荧光体进行了表征和研究。常规的固相反应合成Li（2-x）（MoO4）2：Eux系列红色荧光粉需要在900℃以上的高温才能够形成均一的固溶体，而采用溶胶-凝胶法制取，在700℃就可以形成均一的单相Li（2-x）（MoO4）2：Eux，在750℃就可得到发光亮度最高的荧光体。其亮度是常规固相反应于900℃制得的荧光体的124％。采用溶胶-凝胶法制取Li（2-x）（MoO4）2：Eux系列，可以在相当宽的实验条件范围内得到小粒径、窄分布和高亮度的荧光体，具有良好的颗粒形貌。     

Sirius叠前深度偏移在莺歌海盆地“泥拱模糊带”处理中的应用

在对Sirius叠前深度偏移软件应用开发的基础上,分析讨论了Sirius 2D叠前深度偏移速度模型建立、层析成像及演、叠前深度偏移以及深度聚焦等技术环节的基本原理,并以莺歌海盆地某测线的处理为例,具体分析了Sirius 2D叠前深度偏移处理的流程、主要参数及时效.文中还分析讨论了莺歌海盆地中央“泥拱带”叠前深度偏移处理的地质效果.实践表明,莺歌海盆地广泛发育的与“泥拱模糊带”有关的构造各有其特殊性,只有通过3D叠前深度偏移处理才能从根本上解决“泥拱模糊带”的成像问题.

Thermal and mechanical properties of EPR and XLPE cable compounds

This paper shows that the mechanical and thermal properties of EPR cable dielectrics are very stable with temperature. Commercially available EPR and TRXLPE cable dielectrics typically have about the same thermal conductivity, although the thermal conductivity of TRXLPE above the melting point of the crystallites drops below that of the EPR dielectrics. The mechanical properties of EPR cable dielectrics are much more stable with temperature than those of the TRXLPE, as EPR polymer is essentially amorphous so that EPR cable dielectrics do not suffer from the very large thermal expansion of TRXLPE as its crystallites melt.     

Integrating heterogeneous distributed COTS discrete-event simulation packages: an emerging standards-based approach

This paper reports on the progress made toward the emergence of standards to support the integration of heterogeneous discrete-event simulations (DESs) created in specialist support tools called commercial-off-the-shelf (COTS) discrete-event simulation packages (CSPs). The general standard for heterogeneous integration in this area has been developed from research in distributed simulation and is the IEEE 1516 standard The High Level Architecture (HLA). However, the specific needs of heterogeneous CSP integration require that the HLA is augmented by additional complementary standards. These are the suite of CSP interoperability (CSPI) standards being developed under the Simulation Interoperability Standards Organization (SISO-http://www.sisostds.org) by the CSPI Product Development Group (CSPI-PDG). The suite consists of several interoperability reference models (IRMs) that outline different integration needs of CSPI, interoperability frameworks (IFs) that define the HLA-based solution to each IRM, appropriate data exchange representations to specify the data exchanged in an IF, and benchmarks termed CSP emulators (CSPEs). This paper contributes to the development of the Type I IF that is intended to represent the HLA-based solution to the problem outlined by the Type I IRM (asynchronous entity passing) by developing the entity transfer specification (ETS) data exchange representation. The use of the ETS in an illustrative case study implemented using a prototype CSPE is shown. This case study also allows us to highlight the importance of event granularity and lookahead in the performance and development of the Type I IF, and to discuss possible methods to automate the capture of appropriate values of lookahead.
