In the near infrared band (λλ8000 to 8725A), the spectra of 10 S-type symbiotic stars and 27 K-M type comparison stars have been observed with a moderate dispertion of 33Amm-1, the resolving power signal to noise raho S/N> 100.
在近红外波段（λλ8100-8725A），对10颗共生星，27颗K－M型比较星进行了分辨本领信噪比S／N＞100的光谱观测，对晚于M2的晚型星，出现了TiO三重头（λλ8432，8442，8452A）吸收带，发现吸收带深度对温度（即光谱型）很敏感而对重力（即光度级）不敏感。
Under the background of socialist market economy and the multiplicity of economy, the value tropism of the people has branded the market economy ,and the value tropism of "both win and both survive" has been formed.
在我国社会主义市场经济体制及经济文化多元化的背景下 ,人们的价值取向已打上了市场经济的烙印 ,逐渐形成了“双赢共生”的价值取向。
