ジャーナル フリーThermomagnetic properties, lattice constants and optical properties of Fe-Ti oxide minerals contained in 31 submarine basalt samples from the Shikoku basin (Site 443 of DSDP Leg 58) were studied. It seems to be clarified by this work that the magnetic properties are not dependent on depth from sub-bottom at the drilling site but on their lithological facies. As the result of the thermomagnetic analysis of the magnetic minerals separated magnetically from these samples, they were classified in four types (i. e. 1. reversible 2. semi-irreversible 3. irreversible 4. high Curie temperature). Specimens in the irreversible type seems to be reconstituted by a certain heat treatment. This fact shows us the necessity of reconsideration of the mechanism of a thermo-chemical change in low temperature-oxidized (non-stoichiometric) minerals.抄録全体を表示PDF形式でダウンロード (7038K) -

ジャーナル フリーThe ionospheric scintillation data obtained at Lunping by use of 136.1124MHz beacon signal transmitted from the geostationary satellite, ETS-II, have been used to analyze the diurnal, seasonal and solar cycle variations of scintillation activity. The effect of the geomagnetic activity on the scintillation activity has been studied by use of superposed epoch method. The effect is not unique but depends on season and solar activity.抄録全体を表示PDF形式でダウンロード (822K) -
