In many ultrafast imaging applications, the reduced field-of-view(r FOV) technique is often used to enhance the spatial resolution and field inhomogeneity immunity of the images. The stationary-phase
Single-element combustor experiments are conducted for three shear coaxial geometry configuration injectors by using gaseous oxygen and gaseous hydrogen(GO2/GH2) as propellants. During the combustion
The Positron Emission Mammography imaging system(PEMi) provides a novel nuclear diagnosis method dedicated for breast imaging. With a better resolution than whole body PET, PEMi can detect millimeter-
当一种植物遇到干旱时,它通过激活一组名为受体的蛋白质分子对这种压力做出最好的回应。这些受体一旦被激活,便开启了帮助植物在这种压力下生存的程序。一个细胞生物学家研究小组发现了如何重新接通这种细胞机器以提高植物的应激反应,利用这个发现可以设计作物,使它们在干旱条件下得以生存并增加产量。由加州大学河滨分校的植物细胞生物学副教授肖恩·卡特勒(Cutler)实验室进行的这项研究,将耐旱
To describe both the way in which a wave spectrum grows and the growth processes of realistic wave conditions,the dependence relationship between the spectrum parameters and wind parameters must be ob
Aquarius is the second satellite mission to focus on the remote sensing of sea-surface salinity from space and it has mapped global sea-surface salinity for nearly 3 years since its launch in 2011. Ho
Upper ocean heat content is a factor critical to the intensity change of tropical cyclones(TCs). Because of the inhomogeneity of in situ observations in the North Indian Ocean,gridded temperature/sali
The application of ensemble optimal interpolation in wave data assimilation in the South China Sea is presented. A sampling strategy for a stationary ensemble is first discussed. The stationary ensemb
The principle of ocean wave spectrometers was first presented several decades ago to detect the directional wave spectrum with real-aperture radar(Jackson,1981). To invert wave spectra using an ocean
The first Chinese microwave ocean environment satellite HY-2A was launched successfully in August,2011. This study presents a quality assessment of HY-2A scatterometer(HYSCAT) data based on comparison
