So, after reducing her workload, Xiao underwent IVF treatment. Luckily, she got pregnant after just one treatment cycle, but later experienced vaginal bleeding, and rushed to the hospital. I told her to rest and carry on with the treatment (to prevent a miscarriage). As Zubin Zarthoshtimanesh, a yoga guru, demonstrated postures at a high school stadium in Dujiangyan city, Sichuan province, some 200 students sat on colorful mats watching him closely. It was part of the first IndiaChina international yoga festival in the provincial capital, Chengdu, in Southwest China, where more than 1,000 fans from home and abroad gathered for lessons from 20 leading practitioners of the ancient Indian regimen, from June 1721. Yoga is to India what perhaps tai chi is to China. Many countries other than India and China, also held the first World Yoga Day on June 21, after the United Nations last year agreed to Indian Prime Minister Narendra Modi39。 (16)黃維平,我國海上風電場開發(fā)面臨的機遇和挑戰(zhàn)及解決方案 ,第二屆全國海洋能學術(shù)研討會論文集 ,2021 年。 7 參考文獻 (1)吳佳梁 李成峰 .海上風力發(fā)電機組設(shè)計 ,北京工業(yè)出版社。這就需要國家在大規(guī)模啟動海上風電市場前建立較為完善的技術(shù)支撐體系,對海上風電技術(shù)的研究投入足夠的資金,對包括近海風資源、環(huán)境條件分析、適合我國風資源的海上風電機組和近海風電場建設(shè)等的關(guān)鍵技術(shù)開展研究。 新型海上風力發(fā)電機逐步發(fā)展 直接驅(qū)動同步環(huán)式發(fā)電機、直接驅(qū)動永磁式發(fā)電機等新型海上風力機將會得到不斷的研發(fā)和運行,進一步優(yōu)化發(fā)電機的發(fā)電性能,減少槳葉數(shù)量以減少生產(chǎn)和安裝等成本。 韓國將在釜山前海建造一座年發(fā)電量為 35 萬千瓦時的全國最大的海上風力發(fā)
