blank test solution

The test indicated that the viscosity of test solution is identical with its blank solution and there is not background absorption interference.

试验表明，试液的粘度与其空白溶液的一致，无背景吸收干扰。

The stabilization time of suspension, amount of hydrochloric acid solution(1+1), identity of viscosity for test solution and its blank solution, background absorption interference were studied.
