采用两种常用的粒度反演方法——正则化和Chahine算法,对90nm与250nm单峰分布、50nm与200nm双峰分布、100nm与300nm双峰分布的模拟动态光散射数据,以及105nm、300nm标准颗粒的实测动态光散射数据进行了反演分析.结果表明:噪声水平的高低是影响粒度分布反演准确性的关键因素之一,反演结果的准确性随噪声水平的增加而降低,噪声水平超过某一阈值后,将无法得到有意义的反演结果;不同反演方法具有不同的抗噪能力,在低噪声水平下反演结果无显著差别,随着噪声水平的增加,反演结果表现出很大差异;正则化方法通过正则参数的选择可以有效抑制噪声影响,表现出强于Chahine算法的抗噪能力;与Chahine算法相比,正则化方法不需要假定初始分布,因此,在噪声较大的实验或生产过程中进行颗粒分布测量时,宜采用正则化方法.

Phototherapy, including photodynamic therapy(PDT) and photothermal therapy (PTT), is a promisingmethod of tumor treatment, which has the advantages ofstrong specificity and small side effects. However, PDT willaggravate the hypoxic environment in tumor cells, and PTTwill lead to heat-resistant reaction, both of which will make theorganism quickly produce heat shock proteins (HSPs) toprotect itself, thus seriously hindering the therapeuticefficiency of phototherapy. As a natural HSPs inhibitor,quercetin (QR) provides a feasible way to solve this ***, a kind of metal organic framework (MOF), Fe-TCPP(FT), was used as a delivery material and photosensitizer tobuild a chemo-phototherapy platform, and QR was used as achemotherapy drug and HSPs inhibitor. On this basis, the nanoparticles (NPs) were modified with PEG-CPP30 (a cellpenetratingpeptide that specifically recognizes human breast cancer MCF-7 cells), which showed excellent targetingcapacity and biocompatibility. The combination of chemotherapy and phototherapy significantly improved the anti-cancereffect. At the same time, NPs also showed prominent anti-HSPs effect. The effective connection of the two played acomplementary role in the process of tumor treatment, which provided a new strategy for the accurate and efficienttreatment of tumors in the future.

双基地声呐的接收站因散射主动信号存在暴露的风险,对此提出了基于发射声屏蔽的双基地声呐低截获技术。发射站采用垂直发射阵,利用屏蔽权对原始信号进行预处理,获得的低截获信号在接收站处被自动抵消,从而降低接收站散射信号的能量。仿真结果表明,发射声屏蔽技术能有效增加接收站散射信号到达目标处的能量衰减,而对到达接收站处的待测目标散射信号则无较大影响。该方法突破了以往低截获技术只是改变信号能量时频域分布的局限(在信号处理层面),利用多途结构真实降低了被截获信号能量(在物理层面),并适用于多种信号形式。
