The volatile oil was extracted from water caltrop by steam distillation; it was then analyzed by GC-MS to obtain 16 components, 8 of which were identified. Apocynin was the most abundant one, accounting for 81.41% of the total oil. The in vitro inhibitory effects of the volatile oil on SMMC-7721, MCF-7, Hela, HL-60 cells, and human peripheral blood mononuclear cells（PBMC） were investigated via the MTT method. The morphological changes of the tumor cells were observed and the apoptosis of HL-60 cells was detected by flow cytometry. The proliferation of the tumor cells could be significantly inhibited and the apoptosis of HL-60 cells could be induced by the volatile oil. The proliferation inhibition effect of the volatile oil on HL-60 tumor cells and the induction of the apoptosis of ilL-60 cells had dose-dependent feature.

In this study, a high-carbon nano-bainitic GCr15Si1Mo bearing steel was investigated. Specifically, the effects of content and size of undissolved carbides on the microstructure and transformation kinetics of nano-bainite were analyzed. The results demonstrated that after prolonged austempering at low temperatures, the mixed microstructure composed of nano-bainite (NB), undissolved carbides (UC), and retained austenite (RA) was obtained in GCr15SiMo steel. When the experimental steel was austenitized at 900 ℃, the undissolved carbides gradually dissolved until reaching a stable state with increasing holding time. Furthermore, at the same austempering temperature, despite different volume fractions of undissolved carbides in the substrate, the volume fractions of nano-bainite in the final microstructures remained essentially the same. Moreover, the higher the content of undissolved carbides in steel, the faster the transformation rate of nano-bainite and the shorter the total transformation time.

在体绘制领域和图像分割中,数据集通常具有流形结构,各部分边界连接紧密且伴随局部噪声,给传统聚类算法的应用带来了较大的困难.本文根据非参数密度估计方法提出了一种基于多尺度信息融合的层次聚类算法.新算法通过整合密度差异和边界信息构造了一种多尺度结构信息融合的相似性度量,通过水平集的图连接策略推导出一种层次化的类结构剖析过程以获取稳定的聚类结果.新算法不受数据集形状、密度类型的限制,无需对数据集进行假设,可自动识别数据集常见的聚类结构特征.同时聚类结果较为稳定,算法对噪声具有较强的鲁棒性.从人工数据集和真实数据集以及应用试验的测试结果可以看出新算法的优越性能.

在《德意志意识形态》中,马克思主要向我们阐述了唯物史观的基本观点:从生产劳动看待历史,在劳动发展史中找到了人类发展史的钥匙。因为人的第一个活动是生产劳动,是人为了生存而展开的活动。马克思研究了自己实践哲学新思想与德国思想体系之间的对立,彻底清算了自己的哲学信仰,阐述了自己的唯物史观思想。《德意志意识形态》是马克思实践哲学诞生的标志。
