| 1 | Heating performance of a ground source heat pump system installed in a school building显示文摘The heating performance of a water-to-refrigerant type ground source heat pump system is represented in this paper under the actual working conditions of the GSHP(ground source heat pump) system during the winter season of 2008.Ten heat pump equipments with the capacity of 10 HP each and a closed vertical typed-ground heat exchanger with 24 boreholes of 175 m in depth were constructed.We investigated a variety of working conditions,including the outdoor temperature,the ground temperature,and the water temperature of inlet and outlet of the ground heat exchanger in order to examine the heating performance of the GSHP system.Subsequently,the heating capacity and the input power were investigated to determine the heating performance of the GSHP system.The average heating coefficient of performance(COP) of the heat pump was noted to be 5.1 at partial load of 47%,while the overall system COP was found to be 4.2.Also,performance of the GSHP system was compared with that of air source heat pump. | Jaedo SONG Kwangho LEE Youngman JEONG Seongir CHEONG Jaekeun LEE Yujin HWANG Yeongho LEE Donghyuk LEE | 2010 | Science China(Technological Sciences)2010，53，1： | 5 |

| 8 | Sodium iodate-induced retina degeneration observed in non-separate sclerochoroid/retina pigment epithelium/retina whole mounts显示文摘Background:Sodium iodate(SI)is a chemical widely applied to induce retina degeneration in animal models.SI treatment caused formation of rosettes/folds in the outer nuclear layer(ONL)of the rat retina,but it was previously unclear whether SI also forms rosettes in mice.In addition,SI induced retina degeneration was never addressed in non-separate sclerochoroid/retina pigment epithelium/retina whole mount.Here we displayed features of retina degeneration including rosette formation in mice and developed a morphological analytic assessment using sclerochoroid/retina pigment epithelium/retina whole mounts.Methods:SI was intraperitoneally injected in Sprague-Dawley(SD)rats and C57BL/6J mice using a single dose(50 mg/kg)or with a dose range(10 to 50 mg/kg)in BALB/C mice.Rat retinas were investigated up to 2-week post-injection by histology and whole mounts,and mouse retinas were investigated up to 3-week post-injection by histology,fluorescent staining of sections and/or sclerochoroid/retina pigment epithelium/retina whole mounts for the morphological evaluations of the SI-induced retina damage.Results:SI-induced retina damage caused photoreceptor(PR)degeneration and rosettes/folds formation,as well as retina pigment epithelium degeneration and inward migration.It displayed mixed nuclei from choroid to PRs,due to layer disorganization,as shown by single horizontal images in the sclerochoroid/retina pigment epithelium/retina whole mounts.Measurement of the PR rosette area induced by SI provided a quantitative,morphological evaluation of retina degeneration.Conclusions:The method of non-separate sclerochoroid/retina pigment epithelium/retina whole staining and mount allows us to observe the integral horizontal view of damage from sclera to PR layers,which cannot be addressed by using sectioned and separate whole mount methods.This method is applicable for morphological evaluation of retina damage,especially in the subretinal layer. | Soo-Young Kim Yang Zhao Hong-Lim Kim Youngman Oh Qingguo Xu | 2022 | Annals of Eye Science2022，，1： | 1 |
