On July 27, 2022, a high-precision system for measuring the magnetic field based on a coherent population trapping magnetometer（referred to as the CPT system） was launched onboard the Space Advanced Technology demonstration satellite（SATech-01） by a ZK-1A rocket. The payload comprises a scalar coherent population trapping magnetometer（CPTM）, triaxial anisotropic magnetoresistance magnetometer（AMRM）, and nano star tracker mounted on a non-magnetic telescopic tubular mast. This configuration enables synchronized measurement of scalar and vector geomagnetic fields, as well as the attitude,making the payload with its compact sensors suitable for applications on miniature satellite platforms. On November 7, 2022,the novel telescopic tubular mast was deployed in orbit, extending to a length of 5.28 m. The CPTM, an absolute scalar magnetometer with an omnidirectional sensor, is the first China-developed quantum/atomic magnetometer successfully operating in space. In orbit, the CPTM has sensitivity of ～10 pT/Hz1/2and can automatically operate under complex magnetic field variations. The difference between the scalar fields obtained using the CPTM and CHAOS model has a mean deviation of–3.73 n T and a standard deviation of 26.11 nT（1σ）, without on-orbit calibration or correction. The miniaturized AMRM has a sensitivity of ～0.3 n T/Hz1/2and maintains stable and reliable operation in orbit. The low-power and miniaturized nano star tracker has a measurement uncertainty of 14.23″（1σ） in orbit. The mission has realized the on-orbit technical verification of the integrated and synchronized detection of the vector magnetic field and attitude and fully validated the system's performance,automation level, and reliability.

利用TG-FTIR对松木屑、褐煤及其混合物的共气化过程及气化产物进行了分析,研究了掺混比例、升温速率以及反应气氛对共气化过程的影响。结果表明,松木屑加入后提高了试样的反应活性,随松木屑比例增加,气化失重速率逐渐降低,CO的开始析出温度及析出峰面积ACO呈降低趋势;较低的升温速率有利于CO和CH4的析出,随着升温速率的增加,DTG曲线向高温侧移动,最大失重速率显著增加,褐煤热解对应的峰逐渐消失;CO2气氛对挥发分析出阶段的失重行为影响不明显;空气气氛时挥发分析出阶段的两个失重峰分别对应挥发分的燃烧和固定碳燃烧,该气氛下没有明显的焦炭气化阶段。

以泡沫铝为夹芯,长条薄铝板为面板制备泡沫铝层合梁,对泡沫铝层合梁的三点弯曲变形进行了研究。结果表明:泡沫铝层合梁的三点弯曲变形过程与泡沫铝的相似,层合梁的载荷曲线远远高于泡沫铝和面板的载荷曲线之和,显示出良好的层合效果;泡沫铝层合梁和泡沫铝承受载荷能力随着孔隙率的增大而逐渐减小;且同一孔隙率下泡沫铝层合梁的极限载荷点出现得比泡沫铝极限载荷点迟,极限载荷值约为后者的4～5倍;较厚面板和良好的孔结构可以提高泡沫铝层合梁载荷曲线,载荷分别增加70%和80%左右。泡沫铝层合梁在保持泡沫铝轻质同时,大大提高了其载荷极限,在工程应用中有着良好的应用前景。
