Abstract: Provided are a water-soluble Pd(II) complex, a synthesis method thereof and use thereof as a catalytic precursor. The complex has a chemical name, ammonium dinitrooxalato palladium (II), and a molecular formula of (NH4)2[Pd(NO2)2(C2O4)]·nH2O (n is the number of crystal water). The Pd(II) complex is synthesized by using PdCl2 or [Pd(NH3)2Cl2] as a starting material which is firstly converted into [Pd(NH3)4]Cl2 in ammonium hydroxide, followed by a chemical reaction between [Pd(NH3)4]Cl2 and excessive NaNO2 to produce trans-[Pd(NH3)2(NO2)2] via ligand substitution mechanism, and finally dissolving trans-[Pd(NH3)2(NO2)2] in an aqueous solution of oxalic acid leads to the formation of the target product (NH4)2[Pd(NO2)2(C2O4)]·2H2O. The complex does not contain chlorine and other elements that are harmful to a catalyst, is readily soluble in water and has a low thermal decomposition temperature.

Abstract: The invention relates to an operation diagram-based method for automatically changing a route to turn back in case of interruption. The method obtains an alternative turn-back point according to the position of a fault point and the information of a line turn-back station, calculates a corresponding turn-back plan of the alternative turn-back point according to an operation diagram of the current day, and finally automatically changes an online train route according to the new turn-back plan, so as to realize automatic turn-back of a train after route adjustment in case of interruption. Compared with the prior art, the method has the advantage of being able to keep the compatibility with an existing operation diagram while quickly changing a route in case of partial line interruption, so as to facilitate quick recovery of planned operation after a fault is removed.
