目的研究隐丹参酮皮肤角质类脂体的药效学与其有效成分隐丹参酮的药动学,探讨其药动学与药效学的相关性。方法采用微透析采样法对痤疮大鼠局部组织液进行采样,并用高效液相色谱法测定隐丹参酮的含量;用液相芯片法检测药效学指标IL-1α和AR的含量,以效应-时间-药物浓度绘制曲线并进行相关分析;采用DAS软件对药物效应-血药浓度进行药物代谢动力学与药物效应动力学(PK-PD)模型拟合。结果隐丹参酮皮肤角质类脂体凝胶皮肤局部给药后2 h药物浓度达到峰值,药效动力学指标IL-1α和AR的含量最小值分别出现在大约6 h和4 h,说明药物浓度与药效之间具有一定的滞后性。药效动力学指标IL-1α和AR与隐丹参酮浓度之间的关系符合效应抑制模型。结论初步研究表明,隐丹参酮皮肤角质类脂体凝胶的局部药动学与局部药效学具有一定的相关性。

To study the emission characteristics of typical construction machinery in Chengdu,12 construction machinery (excavators,bulldozers,loaders,and forklifts) under idling mode,moving mode,and working mode,were tested using a portable emission measurement system(PEMS).Under three operating modes,the typical construction machinery in the working mode was higher in the fuel-based average emission factors of PM_(2.5)and NOx,while the fuel-based average emission factors of HC and CO were higher in idling *** the results of investigation on ownership and activity levels of construction machinery,an exhaust emission inventory of typical construction machinery of Chengdu in 2018 was established according to the recommendation *** annual emission of PM_(2.5),NOx,HC,and CO were 1.67×106,1.61×108,3.83×106,and 1.26×107kg,respectively,and the excavator contributed the maximum emissions,accounting for an average proportion of 43.95%.The emission of construction machinery in Chengdu exhibited a clear monthly trend,with the highest from April to October and the lowest from November to *** addition,the exhaust emissions presented an obvious spot-like characteristics,and the high-value areas were mainly concentrated in the surrounding suburban counties such as Shuangliu Wenjiang *** reduce pollution from construction machinery and improve the quality of the atmospheric environment,more effective measures on housing construction and municipal construction should be taken in those districts in Chengdu.

气浮轴承是光刻机等高精度设备的关键部件,其静态特性直接决定设备精度。以真空预载小孔节流静压气浮轴承为研究对象,探究供气压力、真空度、真空腔面积比以及节流孔直径等因素对轴承静态特性的影响。研究发现气膜厚度与轴承的静态特性呈现4个方面相关性:1)当气膜厚度一定时,供气压力越大,轴承承载能力和刚度越大,最大刚度对应的气膜厚度为7~9μm;2)真空度越大,轴承承载能力越小,但真空度对轴承刚度影响较小;3)真空腔的加入使轴承承载能力下降,但为轴承提供了双向刚度,气膜厚度和真空腔面积比与轴承刚度呈负相关;4)节流孔直径越大,轴承承载能力越大,气膜厚度较小时,节流孔直径与轴承刚度呈负相关,最大刚度对应的气膜厚度为6~12μm。当气膜厚度超过20μm时,轴承刚度在上述分析情况下均趋于零。

Science Bulletin 2017年第10期62卷 717-723页

作者： junhui Li Bin Luo Dongyue Yang Longfei Yin Guohua Wu hong Guo astute Key Laboratory of Advanced Optical Communication Systems and Networks School of Electronics Engineering and Computer Science and Center for Quantum Information Technology Peking University Beijing 100871 China stute Key Laboratory of Information Photonics and Optical Communications Beijing University of Posts and Telecommunications Beijing 100876 China School of Electronic Engineering Beijing University of Posts and Telecommunications Beijing 100876 China

When using the image mutual information to assess the quality of reconstructed image in pseudothermal light ghost imaging, a negative exponential behavior with respect to the measurement number is observed. Based on information theory and a few simple and verifiable assumptions, semi-quantitative model of image mutual information under varying measurement numbers is established. It is the Gaussian characteristics of the bucket detector output probability distribution that leads to this negative exponential behavior. Designed experiments verify the model.
