太阳能光伏炼钢实验技术的探索

对在钢铁生产过程中使用清洁能源进行了探讨.提出的太阳能光伏炼钢概念在技术层面上有2个特点:一是光电转化,转换过程直接迅速,而不会伴随任何物质转变和化学变化;二是"脱网",即不与常规的输供电电网相搭接,其目的在于保证系统在能量方面的独立性.采用系统工程方法,对工艺过程、电热转换方式、炼钢反应器和蓄能方式进行了评选、分析和集成,经反复设计和核算,确定了光伏炼钢概念炉的基本参数,独立自主地制成了第一台公称容量为1 kg的概念炉,并成功地进行了多次炼钢实验,完成了太阳能光伏炼钢从理念到现实的跨越.

Tai Ji Quan as antihypertensive lifestyle therapy: A systematic review and meta-analysis

BackgroundProfessional health organizations are not currently recommending Tai Ji Quan alongside aerobic exercise to treat hypertension. We aimed to examine the efficacy of Tai Ji Quan as antihypertensive lifestyle therapy.MethodsTai Ji Quan interventions published in English and Chinese were included when they involved healthy adults, reported pre- and post-intervention blood pressure (BP), and had a non-exercise/non-diet control group. We systematically searched 11 electronic databases for studies published through July 31, 2018, yielding 31 qualifying controlled trials. We (1) evaluated the risk of bias and methodological study quality, (2) performed meta-regression analyses following random-effects assumptions, and (3) generated additive models representing the largest possible clinically relevant BP reductions.ResultsParticipants (n = 3223) were middle-aged (56.6 ± 15.1 years of age, mean ± SD) adults with prehypertension (systolic BP (SBP) = 136.9 ± 15.2 mmHg, diastolic BP (DBP) = 83.4 ± 8.7 mmHg). Tai Ji Quan was practiced 4.0 ± 1.4 sessions/week for 54.0 ± 10.6 min/session for 22.3 ± 20.2 weeks. Overall, Tai Ji Quan elicited significant reductions in SBP (–11.3 mmHg, 95%CI: –14.6 to –8.0; d₊ = –0.75) and DBP (–4.8 mmHg, 95%CI: –6.4 to –3.1; d₊ = –0.53) vs. control (p < 0.001). Controlling for publication bias among samples with hypertension, Tai Ji Quan trials published in English elicited SBP reductions of 10.4 mmHg and DBP reductions of 4.0 mmHg, which was half the magnitude of trials published in Chinese (SBP reductions of 18.6 mmHg and DBP reductions of 8.8 mmHg).ConclusionOur results indicate that Tai Ji Quan is a viable antihypertensive lifestyle therapy that produces clinically meaningful BP reductions (i.e., 10.4 mmHg and 4.0 mmHg of SBP and DBP reductions, respectively) among individuals with hypertension. Such magnitude of BP reductions can lower the incidence of cardiovascular disease by up to 40%.
