민족주의는 세계 근대역사상 가장 강력한 정치?사회역량의 하나이다. 중국의 근대혁명과 건설 과정에서 민족주의 사조는 몇 번에 걸쳐 부침하면서 중요한 역할을 했다. 개혁?개방이후 국제(국내) 형세가 변화해감에 따라 중국사회는 계속해서 일련의 민족주의 사조와 민족주의 행동을 출현시켰다. 민족주의는 당대 중국의 하나의 우월한 역량이 되었으며, 또한 날로 학계와 사회의 중시를 받고 있다. 본문은 당대 중국의 민족주의 사조와 민족주의 사건에 대해 정리하고 귀납시켜 보고자 하며, 그렇게 해서 당대 민족주의 사조의 기본적인 표현을 밝혀보고, 당대 민족주의 사조의 기본적인 특징을 분석해보며, 당대 민족주의 사조가 홍기하는 심층적인 원인을 규명해 보고자 한다. Nationalism is one of the strongest powers in politics and society, and it was an important factor during the Chinese modern revolution. Reform and openness are examples of the changing international situation the Chinese society showed with a nationalistic behavior. Therefore, the Chinese nationalism was one of the most predominant in the academic world. This paper suggests that the case of Chinese nationalism transformed through the cumulative and collective force of economic, social, and cultural evolution. It also suggests that Chinese nationalism will continuously emerge.

The agglomeration behaviour of Mo powder, especially fine Mo powder, has been a major concern. The degree of powderagglomeration is directly related to the uniformity of Mo and its alloy powder mixtures and related target materials. Thisstudy mainly focuses on how to efficiently reduce the soft agglomerates behaviour of Mo powder. Analysis of the micromorphologyand median particle size (D50) of modified Mo powder showed that the soft agglomerates behaviour of Mo powdercan be divided into three stages: drawing, gathering, and sticking. Modification of the Mo powder surface by the polymersurfactant PVP-K30 can effectively prevent the agglomeration of the Mo powder. Additionally, the surface hydroxyl groupsof the Mo powder disappeared, the agglomerate factor decreased from 13.02 to 5.04, and the flowability of the Mo powderwas significantly improved. This is important for improving the grain uniformity and application performance of Mo targetmaterials synthesized from Mo powder.

A novel multifunctional plasticizer, cyclohexyl triethylene glycol oligo-lactate (CTLE) was designed by atwo-step esterification reaction using green non-toxic biomass lactic acid as raw material. Its structurewas characterized by 1H NMR, FT-IR and TOF-MS. Thermogravimetric analysis (TGA), tensile test andleaching test were used to evaluate the plasticizer effect of PVC or PLA blends. Compared with commercialplasticizers, CTLE showed more outstanding thermal stability, flexibility and migration stability. Under the same condition with the addition of 50 phr plasticizer, the CTLE plasticized PVC film hadthe lowest glass transition temperature (TgCTLE-50 = 24.6 C) and the highest initial decomposition temperature(TiCTLE-50 = 265.4 C). In PLA blends, only the CTLE plasticized PLA film could recover after fracture,and the stress relaxation test results showed that the stress value of PLA-CTLE-20 drops sharply to anon-zero value, showing elastic characteristics. We estimate that the excellent plasticity of CTLE is due toits molecular structure. Among them, a large number of polar groups form intermolecular forces withPVC chain segments to make the binding tight, and the ring structure increases the free volume betweenPVC chain segments.
