传统河段洪水预报结果展示普遍为预报时间、预报值以及过程曲线,静态展示的是预报断面预报洪水过程,洪水到达前当前洪峰所在位置并不明确。为此,基于Vue框架和OpenLayers客户端,结合洪水预报结果和区间河道经纬度坐标集,使用turf进行洪峰位置实时坐标更新计算,提出一种新的河段洪水预报动态可视化展示设计。通过利用该设计对大渡河丹巴水文站至猴子岩水电站河段进行预报模拟,实现了预报洪峰“动起来”的效果。结果表明,该设计能够更直观地可视化展示预报洪水传播情况。

Improving turfgrass drought resistance and save-water features are very important to solve water deficiency in turfgrass production and management. This research did some surveys of systematic literature review about turfgrass drought tolerance morphological characteristics, physiological characteristics and water use efficiency, and provided the detailed information for enhancing turfgrass drought resistant and water use efficiency in the future.

Background: Artificial turf is considered a feasible global alternative to natural turf by many sports governing bodies. Consequently, its ability to provide a safe and consistent playing surface regardless of climate becomes essential. The aims of this study were to determine the effects of artificial surface temperature on:(1) mechanical properties of the turf and(2) the kinematics of a turf-sport related ***: Two identical artificial turf pitches were tested: one with a cold surface temperature(1.8°C–2.4°C) and one with a warm surface temperature(14.5°C–15.2°C). Mechanical testing was performed to measure the surface properties. Four amateur soccer players performed a hurdle jump to sprint acceleration movement, with data(contact time, step length and hip, knee and ankle kinematics) collected using CODASport(200 Hz).Results: The temperature difference had a significant influence on the mechanical properties of the artificial turf, including force absorption,energy restitution, rotational resistance, and the height where the head injury criterion was met. Both step length(p = 0.008) and contact time(p = 0.002) of the initial step after the landing were significantly longer on the warm surface. In addition, significant range of motion and joint angular velocity differences were ***: These findings highlight different demands placed on players due to the surface temperature and suggest a need for coaches,practitioners, and sports governing bodies to be aware of these differences.

Ground fire is an igniting phenomenon that is difficult to control and lightning is the main cause of ground fire. The mechanism of lightning-ground fire is very complex. Daxing'anling Mountains forest region is the place that lighting-groundfire occurs more often and regularly. Our study on lightning-groundfire of this zone in 2002 shows: much more soil near the surface and the ground fuel is the matter preconditions of lightning-groundfire, and the weather conditions hasten the occurrence of lightning...

Subtle changes have occurred in China, and interventional radiology has gradually become an independent specialty, separated from diagnostic radiology. This has been called "Interventionalogy", "interventional medicine(IM)", or simply Intervention by our team,and "Interventional Radiology" is used no more. It has even been given the name "Third clinical Medicine" by us. Chinese intervention has established an independent association for interventional doctors, as well as independent interventional societies in many provinces. The national interventional society will likely be set up at some point in time. Chinese interve ntion has set up their own clinical wards, with much attention paid to a clinical, professional, and normalized direction for development, and established special nursing units. According to us, turf battle is meaningless. "The Third clinical Medicine" belongs to all human beings. It could also be predicted that interventional history will follow the same evolutionary rule as other disciplines, i.e., "long divided, must unite; long united, must divide".
