BEING THE CHANGE
A city in central China exemplifies the national vision for high-quality development By Li Qing
在水泥稳定碎石基层施工技术中，对于材料的要求较高，要尽可能选择终凝时间较长、强度较高的水泥，在储存和使用过程中要避免水泥受潮变质，影响到水泥稳定碎石基层施工的质量，水泥质量一定要满足国家的最低标准。在选择粗细集料时，要结合实际情况，可以借助圆锥式破碎机和振动筛网进行破碎筛选处理，保证细集料干燥清洁，不存在杂质，在选择拌合用的水时可以选择饮用饮用水，对水泥稳定碎石进行搅拌和养护，避免水泥中掺入其他杂质，保证水泥砂浆的抗压强度，不符合实际要求的要及时调整，严禁投入使用。
Wuhan, capital of Hubei Province in central China, boasts a large freshwater lake that has become an ecological icon of the city.
Years ago, wastewater was discharged into Donghu Lake, or East Lake, resulting in severe environmental degradation. Then efforts were made to clean up the water and build a greenway. The once stinking lake has been transformed into a popular tourist attraction and a leisure destination for locals.
The over 100-km greenway connects islands, parks and ponds. Trees have been planted by the lake and over 100 species live in the area, including fishes, birds and reptiles. The large-scale ecological restoration program, launched in 2009, highlights the concept of harmony between people and nature.
The FiberHome Technologies Group, a leading equipment vendor in information technology and telecommunications, is one of the largest enterprises in the Optics Valley. From its first product, a communications fiber meeting international standards, it holds nearly all the first records in the field of optical telecommunication in China. About 10 percent of the annual sales revenue is invested in research and development (R&D) to boost innovation for not only the industry but also the development of Wuhan. Many other enterprises with strong R&D ability such as Chinese smartphone maker Xiaomi also have their bases in the zone.
Foreign capital is another engine. Against the backdrop of a turbulent global economic situation, paid-in foreign investment in Wuhan increased by 13.3 percent year on year, totaling $10.93 billion in 2018. Representing the rise of central China, it has become a new magnet for foreign investors.
The East Lake Hi-Tech Development Zone, also known as the Optics Valley of China, is one of the first national-level hitech zones. Located in southeast Wuhan, it is home to emerging industry projects worth 400 billion yuan ($56.7 billion). The 518-square-km zone has several industrial clusters with high technologies such as biology and geomatics.

Opened to the public in 2016, the greenway is car-free, accessible only to walkers and cyclists.
From computer memory to smart cars, and from network security to commercial aerospace, Wuhan is accelerating its pace of innovation, creating new energy for green growth.
Addressing environmental problems has been a crucial measure to pursue high-quality growth. In addition, hi-tech development and further opening up are also at the top of Wuhan’s agenda.
静接动与动接静主要指在后期制作过程中，技术人员可以将固定镜头和运动镜头进行衔接；还可以在固定镜头的运动趋势中寻求合适的剪切点，并且将此剪切点和运动镜头进行衔接。两个镜头之间存在的呼应关系也可以展现运动镜头和固定镜头之间存在的关联。
3.2 光滑面Keyes记分 大鼠牙光滑面龋损只观察到E级、Ds级，Dm、Dx级均未观察到。E级龋损、Ds级龋损中紫地榆不同提取物组与蒸馏水组比较，差异均有统计学意义（P＜0.05）。但紫地榆不同提取物组与NaF组比较，差异无统计学意义（P＞0.05）；紫地榆不同提取物组间比较，差异均没有统计学意义（P＞0.05）。且NaF组未观察到Ds级龋损。见表2。
Earlier this year, the city government adopted 12 policies to attract foreign capital. For instance, foreign-invested unicorns—startups valued at $1 billion or more—will enjoy an incentive of 5 million yuan ($708,700) if they set up shop in Wuhan. R&D platforms led by foreign companies are entitled to a grant of up to 2.5 million yuan ($354,400). In addition, foreign-funded companies enjoy equal treatment as domestic enterprises, improved investment protection, and facilitated registration and other documentation processes.
This year, drawing on the experience of Beijing and Shanghai, Wuhan issued a plan for business environment optimization. It simplifies official procedures, reduces the time needed to complete them, and facilitates trade. This has slashed the time for customs clearance by 10 percent while import and export compliance costs have been cut by more than 10 percent.

“Excluding the first-tier cities along the coast, Wuhan will grow into the most promising, largest, and most competitive emerging city in China,” Yao Yang, Dean of the National School of Development of Peking University, said at a recent forum, expressing the hope that Wuhan would play a key role in the high-quality development of the entire nation.
