The authors investigate the corresponence between the trace form of a Lie triple system and that of a symplectic ternary algebra.In the progress of the note,the authors make use of the relationships among Lie algebras,Lie triple systems,and symplectic ternary algebras,and construct the relation formula of the forms.By this formula,the authors draw the conclusion of theorem about the forms.

The main purpose of this note is to study a Peirce decomposition for a symplectic algebra.The authors define the symplectic algebra by identities which are modified from the symplectic algebra in the paper on the structure of symplectic ternary algebras of Faulkner J R and Ferrar J C.but it is more comprehensive.Throughout the authors assume symplectic algebras over algebraically closed fields of characteristic zero unless otherwise specified.

The NO fluorescence emission spectrum in DBD (Dielectric barrier discharge) was obtained at low pressure. Through detailed analysis, most of the lines are attributed to the A2∑+→X2П1/2,2/3 transition. The possibility of dissociation of NO during the discharge is proved.
