A new kind of phenyl-functionalized magnetic fibrous mesoporous silica(Fe3 O4@Si O2.KCC-1-phenyl) was prepared by copolymerization as an efficient adsorbent for the magnetic extraction of phthalate esters from environmental water samples. The obtained Fe3 O4@Si O2.KCC-1-phenyl showed monodisperse fibrous spherical morphology, fairly strong magnetic response(2. emu/g), and an abundant π-electron system, which allowed rapid isolation of the Fe3 O4@Si O2.KCC-1-phenyl from solutions upon applying an appropriate magnetic field. Several variables that affect the extraction efficiency of the analytes,including the type of the elution solvent, amount of adsorbent, extraction time and reusability, were investigated and optimized. Under optimum conditions, the Fe3 O4@Si O2.KCC-1-phenyl was used for the extraction of four phthalate esters from environmental water samples followed by high-performance liquid chromatographic analysis. Validation experiments indicated that the developed method presented good linearity(0.1-2. ng/m L), low limit of detection(7.5-2. μg/L, S/N =3). The proposed method was applied to the determination of phthalate esters in different real water samples, with relative recoveries of 93%-103.4%and relative standard deviation of 0.8%-8.3%.

A dual-wavelength synchronously mode-locked homogeneously broadened bulk laser operating at 1985.6 and1989 nm is presented for the first time, to the best of our knowledge, which delivers a maximum output power of 166 m W and a repetition rate of 85 MHz. The pulse duration was measured to be 16.8 ps by assuming a sech2.pulse shape. The recorded autocorrelation trace showed frequency beating signals with an interval of 3.8 ps and a full width at half-maximum duration of 2.ps, corresponding to an ultrahigh beating frequency of about0.2. THz, which agrees well with the frequency difference of the emitted two spectral peaks. The results indicated that such a kind of dual-wavelength mode-locked Tm:YAlO3 laser could be potentially used for generating terahertz radiations.

在高强度聚焦超声(HIFU)治疗肿瘤过程中,生物组织损伤是疗效的重要表现,基于B超监控方式研究组织损伤辨识对疗效评价有重要意义。首先提取HIFU辐照新鲜离体猪肉组织前后B超图像的灰度直方图统计特征,通过类间距离评价所提取的不同特征识别生物组织损伤的能力;以类间距离最大的特征作为最佳统计特征,最后采用最大类间方差聚类法(Otsu)自动确定辨识组织损伤的阈值。结果表明:偏斜度特征的类间距离最大,与其它统计特征相比较,偏斜度有较好的区分能力;HIFU区域该特征值在0.575附近时,生物组织出现损伤。利用此阈值对实验获得的样本数据进行测定,可以有效地区分出变性组织与未变性组织。

在激光间接驱动的惯性约束聚变(ICF)中,高强度激光与低密度等离子体发生相互作用,会激发两种受激散射过程:受激布里渊散射和受激拉曼散射。它们会损失激光能量、破坏辐射场对称性、产生超热电子,从而危害聚变点火过程。因此,理解受激散射的物理过程并找到抑制其发展的有效方法,是ICF研究中重点关注的问题。介绍了中国激光聚变研究团队为研究受激散射过程而发展的多个理论模型,以及这些模型在实验数据分析中的具体应用。这些理论模型与实验研究一起,为提升受激散射过程的物理理解发挥了重要作用。
