Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.

根据区域构造演化分析，并结合本文及他人高精度同位素年龄，我们对延边花岗岩形成的大地构造环境有了新的认识：1在华北地台北缘并不存在所谓的加里东花岗岩带，因此，建立在此之上的传统的华北地台北缘演化模式及有关西伯利亚板块与华北板块的碰撞拼合的认识也必然是不正确的；2华北地台北缘和兴凯地块南缘不存在加里东期和海西期花岗岩带，表明两地块边缘最早的花岗质岩浆活动始于晚古生代的二叠纪，即不存在传统观点所认为的加里东期或海西期活动陆缘；3晚古生代由于西伯利亚板块与华北板块的俯冲碰撞，致使地壳和岩石圈增厚，导致加厚岩石圈发生拆沉作用，使得软流圈上涌，加热地壳使之熔融形成岩浆，但玄武质岩浆少量喷出地表，大部分底侵于地壳底部，形成下地壳高密度的玄武质底侵层，玄武质岩浆底侵的热能引起中下地壳广泛部分熔融，形成大面积分布的晚二叠世—早三叠世花岗岩。

The uniphase C with W/≤0.3 can be synthesized without being preheated. When W/ is higher than 0.3, the sample expansion increases with the increase of W content, the reaction between W and C is incomplete, the combustion products consist of W〓C, WC, TiC, C, and unreacted W. Preheating mixtures can accelerate the completion of the reaction among Ti, W, and C. The uniphase C with W/=0.4 can be synthesized by SHS at preheat temperature of 600℃. There are two kinds of powders with size of 2-4μm and size less than 1μm in the combustion products.

通过燃烧前沿激冷淬熄试验及产物形貌特征（燃烧块断面组织和产物多晶聚合体颗粒）分析，创新性地提出了两种体系的自蔓延高温反应机制。1熔化—溶解—析出机制：当燃烧温度较高时，燃烧前沿Ti粉熔化，W和C溶解于熔融Ti里，而后C从熔融里析出。2扩散—固溶机制：当燃烧温度不足以使燃烧前沿Ti粉熔化时，通过C的扩散先形成TiC层，其后C沿着热应力导致的TiC层裂纹继续扩散，与固态Ti核反应生成TiC；同时，C扩散至W颗粒，形成W〓C，而后通过C的继续扩散W〓C转变成WC；与此同时，WC固溶至TiC里，形成C固溶体。

Although most studies dealing with the modification of semi-crystalline polymers with inorganic particles reported embrittling effects by comparing ultimate elongation and impact strength of composites materials with those unfilled resins, some researchers showed that the enhancement of toughness in rigid particle filled polypropylene and polyethylene, in which high filler content is generally required (the volume fraction is about 20%).
