The MHUG technology based on the chemistry of diesel hydro-upgrading reactions has the advantages of flexible product slate and excellent product quality that can in- crease the cetane rating of diesel fuel up to more than 15 units. The hydrotreating and hydro-upgrading catalysts associated with the MHUG technology have outstanding performance to meet the demand of MHUG technology for hydro-saturation and selective ring-opening of aromatic rings. New MHUG process flow scheme can further increase the yield and selectivity of target products. Commercial application of multiple MHUG units has revealed that the MHUG technology designated for clean diesel production features good feedstock adaptability and operating stability.展开更多

This phenomenon results in the weakness of college students＇ humanistic qualities, Therefore, cultivating and enhancing students＇ humanistic qualities in universities of science and technolog become the main issues that are viewed intensively by the current educational circles. This paper analyzes th, current situation of English and American literature optional courses in universities of science and technolog3, gives the importance of offering the optional courses of English and American literature, and analyzes the activ roles and important significance of optional courses of English and American literature in the course of humanisti qualities of students in universities of science and technology. This paper also gives the necessities and ne~ methods of giving the optional courses of English and American literature under the circumstances of colleg, English teaching reform展开更多

According to the serious problem that resource consumption and environmental pollution caused by the traditional building materials, green building materials has been the support of the people. Because of its low consumption, less pollution, beneficial to human health, harmony with the environment and other excellent performance, the green building materials has a rapid development in recent years. This paper is based on the thinking of innovation, starting from the environment, energy saving point of view, analysis the advantages and shortcomings of green building materials, explore the developing trend and future of this new type of material.展开更多

Material wealth stimulates self- awareness of rights protection of the citizens, and that＇s the issue of civil rights that we need to carry out in-depth studies on. As important rights of citizens, how can civil rights gain effective legal protection and how citizens themselves fully and effectively exercise the rights are problems asking for attention in the study of civil rights. Civil rights are not only the issue of inherence and existence, and we should also pay attention to its development or whether there is sustainable development. Moreover, how long this sustainability could last is also the issue of sustainable civil rights this thesis is going to discuss.展开更多

It presents a valuable opportunity for the growth and quality advancement of pharmaceutical science journals. As the only comprehensive English journal of the Chinese Pharmaceutical Association, In the new situation, Journal of Chinese Pharmaceutical Sciences （JCPS） plays a critical role in the communication of new discoveries in pharmaceutical researches to the scientific community. To fulfill the roles as an internationally recognized platform for the communication of the new drug discoveries supported by the National New Drug Innovation Programs, the JCPS editorial office will take advantage of its English language specialty, emphasize quality and digital access, and promote the advancement of the journal.展开更多
