By implementing spectrum factorization on the half-band filters, all the analytic and synthetic filters were constructed.

再对半带滤波器进行谱分解，构造出了各分析和综合滤波器。

The Baichuan Dalian filter media products are made from many different types of synthetic fibres and each fibre has its own spectrum of characteristics.

大连百川滤料产品由多种合成纤维制成，每种纤维都具有自己的独特性能。

RESULTS: the yield of synthetic product, the infrared spectrum of which was conformable to the chemical structure of sodium taurocholate, was over 50%.

结果：合成法制备牛磺胆酸钠收率在50%以上，其红外光谱与结构相符。
