    摘要： A relaxor ferroelectric solid solution single crystal is capable of making transitions, at temperatures below the Curie temperature, between a first state which has a high permittivity and blocks optical transmission and a second state which has a low permittivity and allows optical transmission. The relaxor ferroelectric solid solution single crystal undergoes a transition to the second state if an electric field above a threshold is applied thereto in the first state. The relaxor ferroelectric solid solution single crystal undergoes a transition to the first state if heated to or above the Curie temperature in the second state.

    摘要： Amino acids having masked amino groups react with amino acids having masked carboxyl groups to form peptide derivatives in good yields if the reaction medium contains an isonitrile. Isonitriles also are effective in causing condensation of amino acids having masked amino groups with compounds having active hydroxyl groups to the corresponding amino acid esters. The yields of the first-mentioned reaction are enhanced if the reaction mixture additionally contains one of the compounds having active hydroxyl groups. Both the peptide derivatives and the amino acid esters of the compounds having active hydroxyl groups are useful for peptide synthesis.
