Intensities of 2358 independent reflections were collected with four circle diffractometer using MoKa radiation. After reduction for diffractometer data, we derived first the position parameters of all the V atoms by direct method using SHELXTL program. The coordinates of all the non-hydrogen and hydrogen atoms were obtained from successive Fourier and difference syntheses. The block-diagonal least-squares refinement for all atoms gave a final discrepency factor R = 0.065.The result of structure analysis shows that all the six protons of each decavana-dic acid are captured by six nitrogen atoms involved in three ethylenediamine molecules. In crystal, the isopoly decavanadate anions, cations and the crystal water are linked together by ionic forces and hydrogen bonding and the chemical content within a unit cell has been identified as4[V10O28]6- · 12[H3+NCH2CH2N+H3] · 24H2O.

U., respectively, we made some long-slit spectral observations using the Cassegrain spectrograph attached to the 1-m RCC telescope of Yunnan Observatory. This paper is only concerned with the six nitrogen-baked Kodak 103a-O plates which have a spectral range of 3000-5100A with dispersion 165A/mm and a resolution no less than 7A. The dispersion curve of every plate is obtained by a polynomial fitting of wavelengths...

In March-April of 1986, while Halley's Comet had heliocentric distances about 1 A. U. and 1.5 A. U., respectively, we made some long-slit spectral observations using the Cassegrain spectrograph attached to the 1-m RCC telescope of Yunnan Observatory. This paper is only concerned with the six nitrogen-baked Kodak 103a-O plates which have a spectral range of 3000-5100A with dispersion 165A/mm and a resolution no less than 7A. The dispersion curve of every plate is obtained by a polynomial fitting of wavelengths versus positions of a sequence of strong cometary emission lines. The result of spectral line identification makes clear that CN, C2, C3, CH, NH, OH exist in this comet, perhaps NH2, H2CO, CH+, N also exist. The fact of a number of strong absorption lines, strong continuum and very few ion lines suggests that Halley's Comet is dust-rich. The discovery of OH (3090) emission gives us a clue in the research of development of hydrogen cloud aroud this comet and indicates that the ultraviolet observations at Yunnan Observatory is in an excellent condition.

1986年3—4月间,哈雷彗星的日心距为1和1.5 A.U.附近。我们使用云南天文台1米RCC望远镜和卡焦摄谱仪,取得了7张长狭缝光谱。这是我国唯一的一组哈雷彗星长狭缝光谱。光谱色散度为165(?)/mm,分辨率不小于7(?)。本文主要给出6张Kodak 103_a-O底片上3000—5100(?)波段的谱线证认结果。光谱片上主要出现了CN、C_2、C_3、CH、NH、OH等分子发射线,还可能存在NH_2、CH~+、N、H_2CO等发射线。光谱中连续辐射、吸收线较强,离子谱线少而弱,表明哈雷彗星是富尘的。OH(3090)发射线的出现既证实了卫星观测结果,又说明云南天文台的紫外观测条件是优越的。
