LED场地照明电气特性的研究

智能建筑电气技术 2018年第4期12卷 5-10页

作者：李炳华董青徐学民悉地国际建筑设计顾问有限公司北京100013

为了研究LED场地照明的电气特性及其应用,对7款中外不同LED场地照明灯具的电气特性进行了系统性地试验研究,包括LED灯的启动、过载、谐波、熄弧、电压、调光等特性,并通过两个工程实例比较了LED场地照明与金卤灯的节能效果。结果表明,... 详细信息

为了研究LED场地照明的电气特性及其应用,对7款中外不同LED场地照明灯具的电气特性进行了系统性地试验研究,包括LED灯的启动、过载、谐波、熄弧、电压、调光等特性,并通过两个工程实例比较了LED场地照明与金卤灯的节能效果。结果表明,在电气特性方面,LED场地照明灯对比金卤灯全面占优,LED场地照明系统具备替代金卤灯的技术条件。

Half a century—plus 37 seconds—after it was first introduced to the world,the leap second has been scheduled for *** 18 November 2022 at the General Conference on Weights and Measures(CGPM)outside of Paris,France,representatives of governments around the globe decided that astronomical time(known as UT1),which is determined by Earth’s rotation,will be allowed to diverge by more than one second from Coordinated Universal Time(UTC),which is based on the steady ticking of atomic clocks[1].While the change—not to be implemented until 2035—will go unnoticed by most people,it promises to simplify the timekeeping vital to services provided by a wide range of global industries,including transportation,defense,and finance.

作者： chris Palmer Senior Technology Writer

In a year that had already seen dozens of heat and extreme weather records shattered[1]and temperatures approaching the limit of human survival[2],the Intergovernmental Panel on Climate Change(IPCC)published its latest large-scale report,concluding that the world has warmed 1.1℃ above pre-industrial levels[3].Along with dire warnings for the future,the authors of the March 2023 report issued the hopeful message that many feasible and effective options are currently available to reduce greenhouse gas emissions and adapt to human-caused climate change—they just need to be implemented at greater speed and scale.

The heat pump,an old device dating back to the early 1850s[1],has captured new attention for its potential to help meet climate change *** in large part by legislated incentives and bans on fossil-fuel heating in a growing number of countries,the heightened interest has also spawned improvements in the technology’s efficiency and *** unique benefit is for one device to provide,depending on seasonal needs,both heating and cooling.

Objective: Postoperative pain (POP) following abdominal surgery can vary from a few hours to several days. This acute, unrelieved pain can become chronic, requiring patients to take analgesics on an almost daily basis for comfort. Analgesia using general opioids has many side effects and intrathecal morphine is a good alternative. This study was conducted to evaluate the efficacy of intrathecal morphine (ITM) versus conventional analgesia in the management of postoperative pain in colectomy performed by laparoscopic surgery. Methods: Cohort study conducted at the Hôpital Nord in Marseille, from 01 January to 31 July 2021 in patients aged at least 18 years undergoing anaesthesia for scheduled colectomy by laparoscopic surgery. The primary endpoint was postoperative pain intensity and the secondary endpoints were morphine consumption, treatment side effects and length of hospital stay. Statistical analysis was performed using XLSTAT software. Results: We included 193 patients: 131 in the control group (conventional analgesia) and 62 in the ITM group. We observed: a significant decrease in pain (assessed by numerical scale) in favour of the ITM group in the post-anaesthetic care room, i.e. 3 (±4) vs 1 (±2), p 0 and H2: 2 (±2) vs. 1 (±2);p Conclusion: These results suggest that intrathecal morphine (ITM) in laparoscopic colectomy provides effective postoperative analgesia with low morphine consumption, and a reduction in morphine side-effects compared with conventional analgesia.

作者： chris D.Jones Met Office Hadley Centre

The basics are clear:climate is changing,it is caused by human activity and it is affecting everyone and everywhere now[1]. The good news is that we know what to do about it—we can stop global temperatures rising further if we stop emitting greenhouse gases. But because some sectors (such as agriculture or aviation)will have ongoing ‘hard-to-abate’ emissions,
