It was reported in the literature that the main products from the reaction of LnCl3 and C5Me5M were anionic complexes of the type （ML2）(（C5Me5）n LnCl4-n), where L is Lewis base.

During our study on the reaction of （HP（C2H5）3）2CeCl6 with 4 molar equiv, of C5Me5Na, we have recently succeeded in isolating a neutral species （C5Me5）2Ce Cl （Ⅰ）. （Ⅰ） was identified by elemental analysis, IR and 1H-NMR.展开更多

Burlaga, et al. showed that for increasing heliocentric distance, the frequency range with the spectral indexes around —5/3 is extending to low frequencies. To make an explanation for the observed results, a theoretical study is needed. What mechanism controls the properties of the Alfv(?)nic fluctuations in the solar展开更多
In former works, I proved the followingTheorem 1. Let f（x）, r（t） and δ（x） be three functions satisfying the following conditions: f（x） is non-decreasing and f（x）≥t0 for x≥x0; r（t） is positive,

They were discovered in the silt clay of Xiadian Formation, lower Pleistocene.These insect fossils are of Asilldae (gen. et sp. indet.), Harpalidae (gen. et sp. indet.), Lyetidae (gen. et sp. indet.) and Melolonthinae, Subgen. Holotrichia Reitter. The latter is a new species of the subgenus Holotrichia (s. str.) under the name of Holotrichia (s. str.) beijingensis Wang sp. nov.. It has the same eharacteristics with subgenus Holotrichia as well as the modern Holotrichia (s. str.) szechuanensis in spite of some difference.展开更多
