制备得到的BN为无定形态，合成率较高，残留尿素分解缩聚物较少。
The amorphous BN obtained had a higher yield and less residual condensation product of urea decomposition.
它必须被分解成为尿素，这时也要消耗能量。
该模型的计算值与实验数据和文献数据较一致，可用于尿素合成反应进程中、达化学平衡及高压分解时的气液平衡计算。
The results of calculation are accordant with the data taken from experiments and documents, which can be used for vapor-liquid equilibrium calculation in the course of urea reaction, chemical eq.
