We will obtain some basic properties of the two-parameter quantized enveloping algebra $U_{r,s}^{+}(\\mathfrak g)$. In particular, we will verify that the algebra $U_{r,s}^{+}(\\mathfrak g)$ satisfies many nice properties such as having normal separation, catenarity and Dixmier-Moeglin equivalence. We shall study a concrete example, the algebra $U_{r,s}^{+}(B_{2})$ in detail.
