自从提出中国哲学中不存在西方ontology以后,有一种新的观点,试图为不同于西方ontology的所谓中国哲学本体论作辩护,并欲以此会通中西哲学,这实际上涉及到什么是哲学的根本问题。从逻辑上说,在中国哲学中寻找本体论,仍未脱出西方哲学观念的框架,而会通中西哲学的历史任务则必定要求传统哲学观念的更新。根据唯物史观可以初步探讨出新哲学观念的特征。

Scientific attention has recently been focused on the coupling of the earth's upper atmosphere and ionosphere. In the present work, we review the advances in this field, emphasizing the studies and contributions of Chinese scholars. This work first introduces new developments in the observation instruments of the upper atmosphere. Two kinds of instruments are involved: optical instruments(lidars, FP interferometers and all-sky airglow imagers) and radio instruments(MST radars and all-sky meteor radars). Based on the data from these instruments and satellites, the researches on climatology and wave disturbances in the upper atmosphere are then introduced. The studies on both the sporadic sodium layer and sporadic E-layer are presented as the main works concerning the coupling of the upper atmosphere and the low ionosphere. We then review the investigations on the ionospheric longitudinal structure and the causative atmospheric non-migrating tide as the main progress of the coupling between the atmosphere and the ionospheric F2-region. Regarding the ionosphere-thermosphere coupling, we introduce studies on the equatorial thermospheric anomaly, as well as the influence of the thermospheric winds and gravity waves to the ionospheric F2-region. Chinese scholars have made much advancement on the coupling of the ionosphere and upper atmosphere, including the observation instruments, data precession, and modeling, as well as the mechanism analysis.

In order to obtain homogenous Zn-Bi hyper-monotectic alloys and investigate what mechanism the magnetic field functions,we carried out the solidification experiments of Zn-4wt%Bi,5wt%Bi,6wt%Bi,7wt%Bi, 15wt%Bi and 30wt%Bi alloys under a 18T static magnetic field which was set up in *** quenching was also chosen to further damp the segregation caused by Stokes convection and Marangoni *** results indicated that when the content of Bismuth is 5-7wt%,the superimposition of 18Tesla magnetic field can damp the segregation remarkably,and the size of the second phase particles also is ***,to Zn-4wt%Bi alloy solidified in 18T magnetic field,no spherical bismuth particles are found even magnifying 1000 times by microscope, which hints that the 18T magnetic field may change its solidifying *** Zn-15wt%Bi and Zn-30wt%Bi alloy, due to their strong segregation trend,the 18T magnetic field still cannot damp the Stokes settlement thoroughly even by quenching way,however,no layered bismuth and zinc appears when compared to 0T,large Bismuth block are formed in the lower half part of the sample.

Land cover maps are of fundamental importance in studies of the complex interactions between human activities and global change. Mapping land cover using remote sensing is a traditional but still very active field. In the past 45 years, nearly 30000 papers about land cover mapping were pub- lished worldwide, including approximately 10000 papers published in Chinese. However, most of these studies focus on the local scale. A small number of studies focus on glob- al scale land cover maps but at relatively coarse spatial res- olutions （〉300 m）.

Hepatitis C virus (HCV) infects nearly 170 million people worldwide and causes chronic hepatitis, cirrhosis, and hepatocellular carcinoma. The search for a drug regimen that maximizes efficacy and minimizes side effects is quickly evolving. This review will discuss a wide range of drug targets currently in all phases of development for the treatment of HCV. Direct data from agents in phase Ⅲ/Ⅳ clinical trials will be presented, along with reported side-effect profiles. The mechanism of action of all treatments and resistance issues are highlighted. Special attention is given to available trial data supporting interferon-free treatment regimens. HCV has become an increasingly important public health concern, and it is important for physicians to stay up to date on the rapidly growing novel therapeutic options.
