三维荧光光谱因其数据量大、灵敏度高等优点,在食品科学、分析化学、生物化学和环境科学等领域应用广泛。然而,因为同时存在瑞利散射和拉曼散射,给三维荧光光谱的定量分析和数据显示带来了困难。因此,在数据处理前期,消除散射干扰对其具有重要意义。在已有方法中,对较低浓度溶液和散射峰与物质荧光信号重叠严重光谱的去散射算法的研究相对空白。针对现有问题,提出了一种自适应的三维荧光光谱去散射方法。首先,该方法通过减去每次实验获取的溶剂的光谱基线来校正拉曼散射和背景干扰。然后综合考虑散射峰与物质峰的荧光强度和重叠程度将光谱分为五类情况对应三个重叠等级:无重叠、微弱重叠和严重重叠,分别采用置零法、分段三次Hermite插值多项式算法和高斯拟合-分段三次Hermite插值多项式耦合算法对瑞利散射进行校正处理。此方法基于一维插值,仅对单个发射光谱进行研究,降低了算法复杂度,计算时间较短。通过对酪氨酸、黄腐酸、萘乙酸和罗丹明B四种典型有机化合物进行实验,评估了该方法扣除散射干扰的有效性。并且与现阶段研究中使用最多的Delaunay三角形内插值法进行比较,以重叠区域散射校正后的数据对四种有机化合物分别进行浓度回归,此自适应方法所得的平均决定系数为0.9962,相比于Delaunay三角形内插值法提高了5.04%。同时,通过对比天然有机化合物黄腐酸分别经此方法和Delaunay三角形内插值法进行散射校正后的三维荧光光谱,进一步证明了该方法更好地保持了物质荧光光谱区域的结构特征,有效地避免了过拟合现象的发生。最后,利用该方法对模拟突发污染水样进行监测,验证了此方法具有很好的普适性,有实际应用价值,为三维荧光光谱去散射提供了一种新的思路。

Our previous research results have shown that the Ti-O films with ap.r.priate characteristics possess great potentials for biomaterials application. In this pap.r. using plasma immersion ion implantation and deposition (pIII-D), titanium oxide thin films are fabricated onto silicon wafer. The antithrombogenesis of films is evaluated in vitro through the platelet adhesion investigation. The biological behavior of human umbilical vein en-dothelial cells (HUVEC) on the film surface is investigated in vitro by endothelial cell (EC) culture. Our results reveal that the crystalline Ti-O films exhibit attractive blood compatibil-ity. The in vitro HUVEC-cultured investigation of Ti-O film surface has justified that the biological behavior of HUVECs on different structure surfaces is significantly different. The adherence, growth and proliferation of HUVECs to the crystalline Ti-O film surface are in order, by forming a p.r.ect single layer, preserving the natural original shape and dis-playing the cobblestone road metal rank, and obviously sup.r.or to that on the amorphous Ti-O film surface. According to our study, the crystalline Ti-O film, with prop.r.microstruc-ture, is helpful for seeding ECs and can be used as a functional surface for the adherence and growth of ECs.

Endodontic diseases are a kind of chronic infectious oral disease. Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-p.r.ha. However, it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(rCT). recent research, encompassing bacterial etiology and advanced imaging techniques, contributes to our understanding of the root canal system’s anatomy intricacies and the technique sensitivity of rCT. Success in rCT hinges on factors like patients, infection severity, root canal anatomy, and treatment techniques. Therefore, improving disease management is a key issue to combat endodontic diseases and cure p.r.apical lesions. The clinical difficulty assessment system of rCT is established based on patient conditions, tooth conditions, root canal configuration, and root canal needing retreatment, and emphasizes pre-treatment risk assessment for optimal outcomes. The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for rCT. These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

陶瓷工业的节能降碳对于环境保护和可持续发展具有重要意义,而余热回收是实现节能降碳的有效途径,为了提升陶瓷窑炉中烟气余热的回收效率,研究将纳米陶瓷氧化铝粉和水组成的Al_(2)O_(3)-水纳米陶瓷流体与肋柱结合来协同强化微通道换热器换热性能。采用了非正交多松弛(MrT)格子玻尔兹曼方法(LBM)研究了含肋柱的微通道内Al_(2)O_(3)-水纳米陶瓷流体的流动传热特性,并通过与前人相关工作结果进行对比验证了该模型的准确性与可靠性。具体研究了在肋柱换热总面积不变的情况下,不同肋柱高度hi以及纳米颗粒体积分数φ对微通道流动传热特性的影响。研究结果表明,与平直流道相比,肋柱的加入显著增强了微通道的换热性能。此外,随着φ增大,微通道换热性能增强。在肋柱换热总面积不变的情况下,随着hi的增大,微通道换热性能逐渐减弱,当hi为0.3125时热性能因数TpF最大,综合传热性能与压力损失的表现最好。虽然添加肋柱使得微通道传热性能得到提升,但综合压力损失与传热性能却小于平直表面。研究结果能对微通道换热器内的结构设计与优化提供一定参考。
