Most complete wireless weather coverage available : high and low day temperature in celsius or fahrenheit, weather type icon and text, real feel ( rf ) temperature ( what temperature really feels like ), wind direction, gust and speed in mph, km / h or m / s, uv index ( the sun ' s ultraviolet intensity level ), amount of day precipitations in in, cm or mm, pressure, visibility and more
最完整的無線天氣覆蓋可以利用:攝氏和華氏的溫度高低，天氣類型圖標和描述，實際感覺到的溫度（真正你感覺到的溫度） ，風向，風力和風速，時速或秒速，紫外線指數（太陽紫外線強度等級） ，降雨雪量精確到英寸，厘米，毫米，壓力可見的描述，還要其他的嗎More recently, dr. rosanne di stefano also from the harvard - smithsonian centre for astrophysics and i used the chandra x - ray observatory to detect objects dubbed " quasisoft " x - ray sources in nearby galaxies because of their low temperatures, which are at most four million degrees celsius. that is well below the temperatures expected for " hard " x - ray sources such as neutron stars or stellar mass black holes - which run between 10 million and 100 million degrees celsius - and still hotter than " soft " x - ray sources like white dwarfs
最近羅珊迪史提芬路博士她亦來自哈佛大學史密森天體物理中心和筆者利用錢德拉射線天文臺在鄰近星系偵測到一種奇怪的-射線源，我們稱之為類軟射線源，因為它們的溫度最高只有攝氏400萬度，遠低於一般硬射線源，例如中子星和恆星型黑洞溫度介乎攝氏1千萬至1億度，卻又比軟射線源例如白矮星為高。As the most widely used type of slot antennas, waveguide slots arrays have the advantage of tight structure, easily controlled aperture distribution, and wide band for the nonresonant waveguide slots antennas, which make it be one of the preferred form in antenna domain of high efficiency and low side - lobe
縫隙天線在現代天線設計中有著重要的地位，而波導縫隙天線又是縫隙天線中應用最為廣泛的天線形式。波導縫隙天線有結構緊湊、口徑幅度相位分佈容易控制和頻帶較寬（行波式縫隙天線）的特點，成為了高效率、低副瓣天線的優選方案之一。
