Jianzhu Gangjiegou Jinzhan, 2017 工业化住宅以住宅设计标准化、部品生产工业化、施工安装机械化及生命周期管理信息化为特征。信息化管理是工业化住宅建造参与方信息传递及时、准确的保障,而住宅部品分类与编码又是实现住宅部品乃至工业化住宅生命周期信息化管理的基础。通过分析现有的信息分类与编码体系,提出工业化住宅部品分类与使用通用码与专用码对住宅部品进行编码的方法,并设计了编码的结构与组成;通过该编码实现住宅部品的唯一标识,可为住宅部品质量追溯提供支持。所提出的分类与编码方法可为我国工业化住宅部品的分类与编码提供参考。

Insights for conservation from the Ecological Knowledge Games project
Conservation Biology, EarlyView.Abstract Environmental conservation research requires robust methods for collecting large‐scale behavioral data and engaging diverse stakeholders in decision‐making processes. We (Y.P., A.B.D., and N.B.) created EcoKnowGames (Ecological Knowledge Games), a transdisciplinary project that develops knowledge games for conservation science and data ...

Shiyou jixie, 2015 针对常规完井工艺不能一趟管柱完成注水井的分层酸化、分层注水施工的现状，设计了分层酸化、注水一体化管柱。该管柱主要由封隔器、酸化注水一体化配水器、定压配水器和洗井阀等组成，通过油管加压以及投球等操作，实现由下至上逐层酸化。现场19口井的应用情况表明，该管柱施工成功率100%，层段合格率均达到85%，实现了2层分注井的分层酸化、分层注水一体化完井，节约了作业成本，缩短了占井时间。该技术不改变现有投捞调配工艺，施工简单易行。

Gaoya dianqi实验室中常采用加速老化方法获得硅油的老化试样，并根据试样中溶解气体组分及体积分数判断硅绝缘油的老化状态，但当前实验中仅能施加热应力或电应力，不能较好地反映硅油的真实工况。为解决这这一问题，文中开展了电热应力对硅油产气特性协同效应的实验研究。文中针对PMX-200型硅油，在200 ℃、25 kV下设计了硅油的热电老化、电热老化和电热联合老化等3组加速老化实验，通过对试样中的气体组分及体积分数分析，发现热电老化方式与电热联合老化方式下试样中溶解气体组分及体积分数最为接近，误差在7.41%~16.86%之间 ...

Dianci bileiqi, 2013 为今后实现自然积污规律研究和防污的差异化,对污秽颗粒等效简化模型、大气总悬浮颗粒物（TSP）的粒径分布函数、绝缘表面污秽主要化学成分对应TSP的粒径分布进行了综述和分析,认为可以污秽颗粒可等效简化为球体,使用空气动力学粒径衡量其粒径;建立TSP粒径分布函数拟合模型;分析认为化学成分Ca2+、SO42-、Cl-、SiO2、Al2O3在TSP中的粒径主要分布在1.810μm,010μm,1.810μm,30-40μm,40μm50μm的范围内,最后对自然积污规律研究和防污的差异化进行了展望。
