Coal company adopts new technology to produce cleaner power By Li Xiaoyang
脱离教材的语文实践活动是盲目的。应针对单元教材的要求,设计相应的活动。这样,才能在激发兴趣的同时,完成教学任务,达到教学目的。在语文教学中,我针对初中学生的特点开展了形式多样的语文实践活动。如课前演讲、朗诵比赛、广告设计、找广告牌匾中的错别字、写观察日记等。这些活动,改变了传统教学结构,使语文教学与学生生活密切联系起来。学生感受到了语文学习离不开生活,生活也离不开语文。学生体会到语文学习的价值和意义,将有助于激发学生学习语文的兴趣。
The year 1952 was a memorable year for both Wang Xuezhen, who is an 85-year-old retired coal miner today, and the industry he was engaged in for most of his professional life. That year, Wang, then 18, got his first formal job in a coal mine after a string of badly paid jobs, working for landlords.
It was also the year when China's coal production reached a then record high of 66.49 million tons. It was the culmination of three years' efforts since the founding of the People's Republic of China in 1949 to revive the old mines that had been destroyed or fallen into disuse during the War of Liberation (1946-49).
The mines needed strong workers like Wang, as machines had not yet been introduced to extract and transport coal.
Wang became a new recruit at the Rujigou coalfield in Ningxia Hui Autonomous Region in northwest China, one of the country's oldest mines. It was the start of a lifelong career in coal mining. Later, he became a director.
(1)课程内容的整体性。教师需要在第一次授课时,整体上介绍课程内容,让学生了解整门课程信息,不要形成碎片化知识。这就需要教师十分熟悉课程的能力培养目标,了解每一堂课的教学目标,同时也需要清楚知识体系的前后逻辑关系,让学生对所学知识形成一个详细的脉络。《计算机网络技术实训》课程,需要老师在第一次授课时向学生讲解计算机网络架构,让学生知道每次学习的都是其中一层的知识点。
Advanced technology
In 2018, the total coal production in China was 3.55 billion tons, more than 100 times the volume seven decades ago.
According to a 2018 report by the International Energy Agency, China has been the world's largest producer of coal since 1985.
With progress in technology and equipment modernization, the hard manual labor is a thing of the past. Today, workers staff computers, monitoring the work of automatic machines that are doing their job.
“This makes the production and transportation of coal more efficient,” Li said.
Today, a sophisticated system is employed to monitor the loading of coal on the conveyor belts to avoid potential accidents in transportation. Remote monitoring and control and unmanned machinery rooms have substantially improved production efficiency and safety.
还可以用梨和百合、银耳炖个甜品,如果没有糖尿病,可以加点冰糖,每次15克百合、三四朵银耳、一个梨,一起炖煮,这是一天的量,连续吃上几天,嗓子、鼻子的干热也能缓解。
综上所述,PPP项目的资本结构是融资内容的关键,股东构成和债本比例直接会影响到政府与企业双方的经济效益。对于公共设施的建设,不仅耗时长,资金的使用量也巨大,这就需要政府与社会企业通力合作,每一方都负责自己应尽的职责,做出各自的贡献,能够有效促进建设项目的顺利完成,并且还能够获得一定的经济效益,对促使政府与社会企业长久的合作有积极的作用。
Li Wei, director of the monitoring center of Hongliu, told Beijing Review that in the past, when there was a problem, it would take at least an hour to identify and rectify it. But now, remote control technicians can make the malfunctioning equipment start working in minutes.
When the Hongliu coal mine, another mine under CHN Energy in Ningxia, was opened in 2011, almost 50 percent of its operations were automated, according to Zhao Zhizhi, Manager of Hongliu.
Green efforts
Liu Baohua, deputy head of the National Energy Administration, said at a press conference that over 70 percent of the coal-fired power plants in China have achieved ultralow emissions.
In 2016, Rujigou Anthracite Co., a subsidiary of CHN Energy that operates the mine, began to clean up the pollution caused by mining. It stopped all coal mining in the ecological buffer zone of the Helan Mountain National Nature Reserve and invested 83.36 million yuan ($11.6 million) to restore the local environment.
“Excessive mining in the past led to environmental pollution, while chaotic competition pushed coal prices overly low. After a ban on overexploitation, the environment and profits of local coal mines have both improved,” Wang told Beijing Review .
4.作文课堂单调少趣,作文评价轻描淡写。丰富多彩的作文课堂不仅能调动学生写作兴趣,还能有效提升学生写作能力。当前我校作文课堂模式较为单一,先理论后写作,作文教学方法如何创新化、多样化、轻松化是急需思考的。作文评价是作文教学的重要环节,是师生双向交流的主要形式。有的老师轻视作文评价,轻描淡写,寥寥数语。忽视了应带着学生去发现问题、总结问题、反思问题,以致作文批改“徒劳无功”。从调查中可以发现,绝大部分同学希望能亲身参与到作文评价中,因此我们教学应多创造学生自评,学生互评,师生互动的环节,让学生在实践中思考,参与中提高。
The quality of the air in the mountains has improved over the past when workers needed to wear masks, said Wang Baoming, chief engineer of Rujigou Anthracite. Over 2,000 willows have been planted this year to make the black mountains green.
To reduce emissions caused by coal burning, coal-fired power plants under CHN Energy are upgrading their production systems. All its coal-fired power generation units meet the national emissions standards, which parallel those of Japan and are stricter than the United States' and the EU's. Also, the group has 180 million kw of installed thermal power capacity, accounting for 15.8 percent of the country's total.
“Those days, we mostly used shovels to dig out coal. I would haul 2 tons of coal from the mine every day,” he told Beijing Review . “Now, everything has changed. Trolleys and shovels have become history. The whole industry has been overhauled with modern equipment, advanced technology and scientific management.” The Rujigou coal mine is owned by CHN Energy, the largest coal mining company in the world with its annual production capacity totaling 560 million tons.
Around the time Wang retired, outdated and depleted mines began to be shut down to improve the environment and cut overcapacity. In the Rujigou coalfield, only one mine is still in operation.
风电齿轮箱是风力发电机组中应用广泛的重要大型机械部件,表面防腐、防蚀涂装是其生产制造必不可少的一道重要工序[2]。如美国GE WIND公司、西班牙GEMESA公司、法国ALSTOM公司以及国内中船重工海装风电公司、东方电气风电公司、华锐风电公司等多数风电齿轮箱使用企业,均将油性漆作为齿轮箱表面涂料指定用漆。本文以某大型高速齿轮制造企业年产2 917台风电齿轮箱涂装生产线为研究对象,运用工业代谢分析方法分析风电齿轮箱涂装生产线的资源代谢过程,定量分析涂装过程中的资源流动,剖析资源代谢特征,从优化代谢过程和减少污染排放的角度,对涂装线工艺代谢系统优化设计提供建议。
In the production zone of CHN Energy Taizhou Power Generation Co. in Jiangsu Province in east China, the smoke issuing out of the chimneys is almost as white as the clouds in the sky, thanks to improved technology. It is a sharp contrast from the earlier coal-fired power plants belching out black smoke and ash.

According to Chen Xuwei, general manager of the company, the white stream is actually steam as a result of technologies such as the desulfurization of coal for ultralow emissions, notably carbon emissions.
The company has also installed nets to prevent the spread of coal ash, Chen said.
