【導(dǎo)讀】不由它本身決定，由與之相連的負(fù)載電阻決定。在近似恒壓源供電系統(tǒng)中，負(fù)載獲得的功率P=UI=RU2，負(fù)載增加既是負(fù)載電流增大，相當(dāng)于負(fù)載電阻減小。說(shuō)，對(duì)同一外部電路而言，二者的伏安特性相同，那么兩種模型可以等效互換。件上所產(chǎn)生的電流和電壓的代數(shù)和。疊加定理只能分析計(jì)算線性電路中的電流和電壓，不能用來(lái)計(jì)算。的大小有直接關(guān)系。出的功率全部是有功功率，電源設(shè)備得到充分利用。的大小說(shuō)明了電源設(shè)備的容量被利用的程。度，低功率因數(shù)將造成電源設(shè)備的浪費(fèi)。性能，使起動(dòng)轉(zhuǎn)矩增大，起動(dòng)電流減?。换蛘哂脕?lái)調(diào)節(jié)異步電動(dòng)機(jī)的轉(zhuǎn)速。于500V的稱為低壓控制電器。
【正文】 ious, and thus have a much older audience base. If we were to run this program on Hunan, we may attract twice as many viewers, says Zhang. But since we didn39。t make it there, we now have to make the best out of the given conditions. And it means we have to make certain promises. When the current season of Rising Star ends, Zhang says his pany will conduct an overall evaluation of the program and make adjustments for future seasons. Although audience ratings haven39。t lived up to Zhang39。s expectations, he says the program has already helped CCTV attract more young people. According to Enlight Media, the number of people ages 15 to 35 who watched the first episode of Rising Star was 76 percent higher than the usual audience for CCTV entertainment productions. In order to attract young audiences, CCTV has been working with independent production panies. As one of CCTV39。s closest partners, Enlight Media has produced several entertainment and reality shows for the pany39。s channels, including the Chinese version of The Biggest Loser on CCTV39。s business channel and an original teenager talent show Shaonian Zhongguo－ qiang (Strong Young Chinese) on CCTV1. This year CCTV also licensed EEMedia, the producer of the popular Super Girl talent shows, to produce the talk show Hi! 2020, hosted by Taiwan pop star Harlem Yu and one of China39。s most popular TV stars Xie Na. The show is geared toward younger audiences. Canxing Productions, which rose to fame with the success of its Voice of China series on Zhejiang TV, also produced two talent shows for CCTV. One is an original production called Songs of China, which ended up as one of CCTV39。s most watched programs of 2020. The State Administration of Press, Publication, Radio, Film and Television announced earlier this year that, starting in 2020, only one music talent show can be aired nationwide during prime time each season, and there can be only one program based on foreign formats each year. However, domestic media report that such policies don39。t apply to CCTV, meaning it will bee a highly desired platform by production panies. Wang Changtian, CEO of Enlight Media, confirmed to the Shanghai Securities News that its programs scheduled to air on CCTV next year, which include at least two reality shows, won39。t be affected. A kung futhemed reality show, produced by Canxing, is also reportedly scheduled to run on CCTV next year. CCTV is very active. The level of its acceptance of new ideas is even beyond my imagination, says Zhang Hang. Our cooperation with CCTV will surely continue. When winter es, nothing is more relaxing than a hot spring bath. For thousands of years, natural mineralrich hot spring baths have also been used to relieve health ailments.
