 We have set up a universal threemolecule autocatalysis reaction model having nonlinear end, and emphatically studied the stability of reaction system having dual nonlinear end in this paper. This paper is divisded into two parls. In the first part, we disscuss the evolutal stability of reaction system having dual nonlinear end of different kind intermediate preducts and its fluctraction character at the critical point. It makes clear that the steadystate solution and unstable limit of its... We have set up a universal threemolecule autocatalysis reaction model having nonlinear end, and emphatically studied the stability of reaction system having dual nonlinear end in this paper. This paper is divisded into two parls. In the first part, we disscuss the evolutal stability of reaction system having dual nonlinear end of different kind intermediate preducts and its fluctraction character at the critical point. It makes clear that the steadystate solution and unstable limit of its reactivediffusive equation and nonlinear Master equation are analysed and researched: The fluctuationdissipation character in evolutal process is varying between the threemolecule model having different dual nonlinear end and the threemolecule moldel having linear end. The stability condition of their thermodynamic bifurcation also have difference. Furthmere we see this reactien systenm having many unstable limit points.  我们建立了一个具有非线性终结的三分子自催化反应的普适模型,考察其中所含的二重非线性终结反应系统的稳定性,本文(Ⅰ)讨论非同种中间产物,同种中间产物在文(Ⅱ)中讨论。本文对非同种中间产物的二重非线性终结反应系统的演化的稳定性及其临界失稳点的涨落特征进行了分析,对其反应扩散方程及非线性主方程定态解和失稳极限的研究表明:异二重非线性终结三分子模型与线性终结的三分子模型的涨落耗散特征有所不同,其热力学分支的稳定条件也有差异,同时还发现该三分子反应系统具有多个失稳极限点。  The thermal decomposition of some liquid energetic materials such as TEGDN,TMETN,NG,and GAP and some energetic materials that could melt when they are heated such as HMX,RDX,PDADN,DATH and TNT are investigated when they were at liquid state by using the differential scanning calorimetry (DSC) and the pressure differential scanning calorimetry (PDSC).At different pressure,the different changes of the thermolysis enthalpy, ΔH ,and the peak temperature of the DSC curve, T m,are discussed.With pressure increasing,... The thermal decomposition of some liquid energetic materials such as TEGDN,TMETN,NG,and GAP and some energetic materials that could melt when they are heated such as HMX,RDX,PDADN,DATH and TNT are investigated when they were at liquid state by using the differential scanning calorimetry (DSC) and the pressure differential scanning calorimetry (PDSC).At different pressure,the different changes of the thermolysis enthalpy, ΔH ,and the peak temperature of the DSC curve, T m,are discussed.With pressure increasing, ΔH will increase and T m will be larger because pressure can restrain the sublimation or volatilization of these energetic materials.The autocatalysis reaction,the second reaction between gaseous products and the competition of the decomposition between backbone and branch are intensified by increasing pressure. T m of DSC curves of the compounds containing N 3 will not chang after pressure restrain their sublimation or volatilization and the thermolysis of these compounds shows special laws compared with other energetic materials.  利用常压差示扫描量热 (DSC)和高压差示扫描量热 (PDSC)的方法研究了HMX、RDX、TEGDN、TMETN、NG、PDADN、DATH、GAP和TNT等含能材料液态热分解时的分解放热焓、分解峰温在不同压力下的变化规律。结果表明 ,压力可以抑制这些含能材料的升华 (挥发 ) ,从而使其分解放热焓增大 ,分解峰温相应发生后移。压力可以使某些含能材料 (如TMETN、TEGDN、PDADN、DATH等 )液态分解时的自催化反应、气相产物之间的二次反应、主侧链竞争分解等一系列反应加强 ,并使其分解表观活化能发生变化。含叠氮基 (—N3)的化合物在压力抑制其升华 (挥发 )后 ,分解峰温不再受压力影响 ,其热行为呈现较特殊的规律  The kinetic investigation of hydrazine reduction chemical plating nickel on the surface of hexagonal boron nitride with the average diameter 104 μm particles has been carried out. A model, extensioncontraction autocatalysis reaction interface, was created which can demonstrate the curves of deposited nickel with time.

The kinetic investigation of hydrazine reduction chemical plating nickel on the surface of hexagonal boron nitride with the average diameter 104 μm particles has been carried out.
