The foreign and domestic technology conditions and development tendency of product pipeline were assessed. In allusion to the rapid development of Chinakazakhstan and Chinarussia multinational pipelines, the difference between China and Russia standard were carried out recently. But the oil product pipeline was not involved. The comprehensive operation standard of Russia oil product pipeline was selected. The advantages of the standard were expounded, including detailed oil product arrangement principle, and decreasing the mixing oil by using process buffing piston and limiting the original process mixing oil, and the determination of allowable minimum flow velocity, and strictly controlling the mixing oil cutting concentration, quantitatively blending calculation of mixing oil. Finally, recommendations were made to raise the level of operation standards of Chinese oil product pipeline.

The corn straw was hydrolyzed by diluted acid via microwave radiation under the conditions of the metal salt ferrous sulfate as catalyst. The effect on the reducing sugar production rate was investigated by the concentration of ferrous sulfate, sulfuric acid content, ratio of liquid to solid, the microwave radiation power, time and pressure. The results show that the product yield can reach 38.5% under the best hydrolysis conditions: ferrous sulfate mass fraction of 3%, sulfuric acid mass fraction of 2%, mass ratio of liquid to solid 15, the microwave radiation power 187.5 W, the microwave radiation time 30 min and the microwave radiation pressure 0.3 MPa. Compared to the method without ferrous sulfate or without microwave radiation, this method shows higher yields by 1.1 and 2.8 times, respectively. 
