为有效量化云制造服务共享平台中企业间的合作信任关系,分析了共享平台的运营模式,提出了一种综合考虑服务满意度与服务满意度波动性的服务综合信任评价模型。首先,建立评价指标体系量化服务满意度,以时间衰减函数表征服务满意度随时间的变化关系;然后,利用虚拟资源包的历史服务满意度信息,提出计算全局服务满意度的方法;最后,以服务满意度波动大小作为奖惩依据对全局服务满意度进行修正,得到虚拟资源包的服务综合信任值。数值实验验证了该模型使用的时间衰减函数和奖惩机制的可行性以及对监测企业提供不稳定服务的有效性。

[Objectives] The aim was to study chemical components of cultivated and wild Pinellia ternate(Thunb.) Breit and Typhonium flagelliforme(Lodd.) Blume by metabolomics technology based on UPLC-ESI-HRMS^n. [Methods] Chemical components of 27 samples of cultivated and wild P. ternate and T. flagelliforme were detected by using UPLC-ESI-HRMS^ntechnology. Differential markers between P. ternate and T. flagelliforme as well as cultivated and wild P. ternate were screened and identified by principal component analysis(PCA) and orthogonal partial least square-discriminate analysis(OPLS-DA). [Results]12 components of P. ternate(cultivated and wild variety) and *** and three components of cultivated and wild P. ternate were screened and identified by OPLS-DA. N-Acetyl-6-hydroxy-L-tryptophan and N-Phenylacetylglutamic were not detected in P. ternate,and these two components can be used as potential markers of P. ternate and T. flagelliforme. [Conclusions]UPLC-ESI-HRMS^n-based metabolomics technology could be used to quickly identify the chemical constituents of P. ternate and effectively distinguish P. ternate and T. flagelliforme,which has reference significance for the quality control of P. ternate.

[Objectives] To establish infrared fingerprints of different parts of Boenninghausenia albiflora(Hook.) *** Meissn. and Boenninghausenia sessilicarpa Levl.(two sources of Yi medicine Ebazema) and analyze the similarity between them. [Methods] The infrared fingerprints of powder of B. albiflora(Hook.) *** Meissn. and B. sessilicarpa Levl. were measured, and the common peak rate and variation peak rate of six samples were calculated to establish the sequence analysis method of common peak rate. [Results] There was a very high common peak rate(≥81.3%) and a very low variation peak rate(≤15.4%) between S1 and S4 as well as S2 and S6. There was a low common peak rate between S1 and S3 as well as S3 and S4, and the common peak rate was 42.9% and 47.6% respectively. There was a low common peak rate(≤47.6%) and a high variation peak rate(≥100.0%) between S1 and S3 as well as S3 and S4. [Conclusions] The method is simple and convenient to operate, can quickly identify different parts used as medicine of B. albiflora(Hook.) *** Meissn. and B. sessilicarpa Levl.(two sources of Yi medicine Ebazema), and provide a new method to judge whether the two are equivalent when being used as medicine and quality evaluation.

以什么样的态度对待马克思恩格斯列领导思想是个根本问题。我们对待马克思恩格斯列宁领导思想的态度是科学的态度,即实事求是的态度。作为马克思主义领导思想的重要组成部分,马克思恩格斯列宁领导思想是与时俱进的科学理论。它以辩证唯物主义和历史唯物主义为武器,建立在科学的世界观和方法论之上;它具有开放性,始终处在发展变化中。这种与时俱进的理论品质,正是马克思恩格斯列宁领导思想始终保持蓬勃生命力的关键所在。真正做到以科学的态度对待马克思恩格斯列宁领导思想,需要坚持整体原则、求实原则、历史原则、发展原则、创新原则。

光谱信息和空间信息相结合在高光谱遥感图像分类领域是提高分类准确率的一种手段.因此提出了结合两种光谱-空间特征的分类方法:一种是使用保边松弛算法对图像进行保边去噪预处理,然后使用卷积神经网络提取光谱维的特征;另一种是先对预处理后的图像的光谱维降维,取像素的一定邻域大小形成的图像块,并使用另外一个卷积神经网络提取图像块的空间特征;然后将这两个提取的特征串行拼接,最后使用支持向量机进行分类.为了验证本文提出的方法的有效性,在两个常用的高光谱图像数据集进行分类实验,结果显示提取的两种特征光谱-空间特征结合后能有效提高图像分类准确率.

通过河岸渗滤作用(riverbankfiltration,RBF)诱发河水的补给,增大地下水的允许开采量可以满足更多居民生活饮用水需求.受人类活动的影响,河流等地表水体遭受苯胺污染,可能通过RBF进入地下水,以致饮用该地下水存在健康风险.为研究反硝化条件下,苯胺在RBF中的转化,采集渭河河床沉积物及沿岸地下水含水层的含水介质,装置土柱,进行土柱动态模拟实验.经过153d的实验研究发现,利用苯胺对RBF中土著反硝化微生物进行驯化,大约经过37d菌种完全适应.具有该菌种的RBF系统,对苯胺具有巨大降解能力,在NO3--N约为23.0mg/L的条件下,RBF系统可使40、80甚至400mg/L浓度的苯胺100%降解,矿化率分别达97.99%、91.39%与75.30%.反硝化条件下,苯胺在RBF中的降解仅有少部分经过脱氨作用,绝大部分与腐殖质以共价键形式形成耦合物,该耦合物更易为微生物降解,且降解过程中不产生对研究环境微生物有毒的中间产物,可实现反硝化条件下RBF中苯胺的连续降解.
