In this paper we describe the designing principles of high-quality achromatic waveplates (quartz + MgF 2 ), control of optical quality of crystal materials, control of delay errors and the question of gluing of waveplates.

Polarity-reversed features are features in the chromospheric magnetic field where the polarity is opposite to that of the underlying photosphere. From over 300 pairs of photospheric and chromospheric magnetograms obtained at Huairou Station, the real

During the international campaign of June 1991, the active region AR 6659 produced six very large, long-duration flares (X10/12) during its passage across the solar disk. We present the characteristics of four of them (June 4, 6, 9, 15). Precise meas

The inhomogeneous distribution of brightness in a split-element filter is discussed. This inhomogeneity is caused by the off-axis effect of the birefringent crystal and can seriously affect astronomical observations in the case of a large field of vi

Statistics of solar radio observations during the period 1970 January –1973 June show that for 95% of the solar proton flare events, the region above the flare was already free of meter wave Type-I sources about one day before the event, while if T
