Poverty–stricken populations must be identified precisely in the fight against poverty to implement the strategy of building a moderately prosperous society in all respects by 2020. The analysis based on the household survey in 2013 shows that the targeting accuracy is not high based on the standard of income and the accuracy is higher based on the standard of multidimensional poverty index. But the latter still has a low coverage rate. To gradually achieve integration of the rural poverty line and the rural subsistence allowance line, standards applied to identifying households entitled to subsistence allowances should be changed from the standard of income to multidimensional poverty indexes. A unified standard of subsistence allowances and a unified method for identifying related households should be developed. At the same time, coverage and funding of subsistence allowances should be extended and increased to better meet people's basic needs.

针对齿轮箱的故障诊断的优化问题,提出了一种基于参数优化的变分模态分解(VMD)与卷积神经网络(CNN)相融合的故障诊断方法。该算法首先通过鲸鱼优化算法对VMD算法进行优化,之后通过正交实验法与粒子群优化算法进行了CNN模型中的重要参数进行优化,最后将分解后得到的固有模态分量输入CNN模型中进行训练学习。诊断完成后得到训练与检测结果,其中经过算法优化后CNN模型的训练与检测准确率可达98.7%与95.7%,优于未优化的准确率94.3%与91.8%。通过对结果的分析验证出该算法的可行性以及在诊断成功率方面的优越性,实现了故障特征信息的自适应性提取,并将故障类型进行分类,最终实现齿轮箱故障诊断的智能化。

《普通高中化学课程标准（实验）》指出：有效的化学学习活动，不能单纯的依赖、模仿与记忆。动手实践，自主探索与合作交流是学生学习化学的重要方式。在新课程理念下，我们必须改革课堂教学，把思考还给学生，让学生成为课堂的主人。在课堂实践中尝试让学生进行探究性学习，在探究中思考，在探究中培养学生的思维能力。下面以乙二酸受热分解及产物检验的实验设计为例，谈谈这类探究式教学法的心得。

鼻咽癌(nasopharyngeal carcinoma,NPC)是头颈部最常见的恶性肿瘤之一,对其进行精准的分期有助于指导个体化治疗方案的实施。目前,临床上主要依靠磁共振成像(magnetic resonance imaging,MRI)进行NPC分期,而常规MRI只能根据肿瘤形态学改变进行分期,具有较强主观性。动态对比增强MRI、扩散加权成像、体素内不相干运动成像、扩散峰度成像等功能MRI技术通过定量测量,使得对NPC分期评估更客观,但目前这些技术及其参数值对NPC分期的评估尚未形成统一标准。人工智能从影像图像中挖掘到更多信息,在未来有很好的应用前景。本文通过综述这些技术在评估NPC分期的价值,以期为临床诊治提供可靠依据,并为未来研究提供参考。
