Generally speaking, titanium has poor for geability and therefore the threshold to invest in the titanium forging operatio n is high. Process parameters have been discussed and computer simulation on the forging processes has been conducted and compared with the forging practices. N ormally, titanium rod was preferred billet on titanium golf club head forging, w hich is the case on iron head, but it is not appropriate on wood head because of its large hollow volume. Therefore, a study on wood head forging from titanium plate has been explored and simulation of the forging processes have been conduc ted and shown reasonable results. DEFORM software has been adopted in the study of the forging processes simulation on the titanium golf head forging simulation . Some successful results will be demonstrated in this paper.展开更多

Considering figures, growth habits and ecological characters of landscape plants, various trees, shrubs, grasses, vines and water flowers are arranged reasonably in different functional areas. In terms of plant selection, tree species adaptive to local climate are adopted, more efforts given to the seasonal aspects, lines, colors, layers, balance, and rhythm, so as to create a garden-like golf course in a short term.展开更多

The results show that shallow groundwater and deep groundwater are polluted to different degrees, and the pollution of shallow groundwater is very serious. In terms of distribution space, the monitoring well in the downstream direction of golf course is the most seriously polluted.展开更多

The role of these ecosystems in continental and Mediterranean climates though, is not yet clearly understood because environmental limiting factors and management intensities can strongly influence the overall C budget. The aim of the present study is to improve the understanding of the mechanisms underlying C fluxes in a turfgrass ecosystem and to assess its C sequestration potential by estimating the annual C budget. NEE （Net Ecosystem Exchange） of turfgrass was calculated in its seasonal variation over one year, and compared between areas characterized by different degrees of maintenance. The C sequestration potential of the turfgrass was investigated in a golf course near Verona （Italy）, adopting a small-chamber enclosure approach. The measurements of gas exchanges between biosphere and atmosphere, permitted to estimate the NEE, as a function of different management intensities. The intensity of management seems to have influence on its C balance. This study needs further research to understand which maintenance variables are determinant on turfgrass C sequestration.展开更多

文摘Drag across a golf ball can affect distance traveled when hitting a ball. An average golf ball will have a drag coefficient of, 0.24 CD ReD 35 m/s. This research found that a significantly deeper dimple pattern will greatly affect the boundary layer, thus changing the drag coefficient and boundary layer.
