  混合添加剂
     The experimental results indicated that the mixed additives (M1- DTBP+TBPB, M2-DTBP+DTAP, M3-DTBP+TBPB+DTAP +TBHP) were better than the single additives for HCCI fuel, since the ignition and heat release timings advanced and the peak of heat release rate increased at different engine speeds and steady the operating conditions. Moreover, with the increase of engine speed, the influence of mixed additives on HCCI combustion was more obvious.
     经试验证明,混和添加剂(M1为DTBP与Tert-butyl peroxy benzoate-TBPB的混合、M2为DTBP与Ditert-amyl peroxide-DTAP的混合、M3为DTBP、TBPB、DTAP与TBHP的混合)均优于单一添加剂,即混合添加剂使得着火和放热提前,燃烧放热率峰值升高,并且发动机转速越高,混合添加剂对HCCI的燃烧影响越明显。

It was concluded that the toughening mechanism of mixed additives is to allow the plastic strain of a PBT matrix at very high strain rates.
      


The effects of Li_2O, MgO and Li_2O+MgO on β″-alumina formation, microstructure and electrical properties are investigated. Li_2O has dominant effect on β″-alumina formation and consequently increases the electrical conductivity but is less favorable in controlling grain size compared with MgO. Mixed additives show different effects with different concentrations. Excessive additives are not desirable due to the deposition on the grain boundary and increase in electrical resistivity of the grain boundary....

研究了Li_2O、MgO和Li_2O+MgO等添加剂对β″-Al_2O_3的形成、显微结构以及电性能的影响,与MgO相比,Li_2O更有利于β″-Al_2O_3的形成,因而有较高的电导率,但也较易促进晶粒长大。混合添加剂的效应随组成不同而异。过量的添加剂由于沉积在晶界,增加晶界电阻率,从而产生不利影响。

This paper discribes the degradation phenomenon formed in the long-term cyclic charge and discharge of fast ionic conductor Na-β-Al_2O_3. Besides the rapid degradation (mcdel Ⅰ) generally assumed, there exists also a slower degradation (model Ⅱ)which starts at the grain boundaries or the phases between grains of the materials and accompanied by the recombination of electron-ions as well as the decline in electric properties such as electric conductivity etc. untill the failure of its mechanical structure.In...

This paper discribes the degradation phenomenon formed in the long-term cyclic charge and discharge of fast ionic conductor Na-β-Al_2O_3. Besides the rapid degradation (mcdel Ⅰ) generally assumed, there exists also a slower degradation (model Ⅱ)which starts at the grain boundaries or the phases between grains of the materials and accompanied by the recombination of electron-ions as well as the decline in electric properties such as electric conductivity etc. untill the failure of its mechanical structure.In addition, it points out that calcium ion is a very harmful additive for this sodium--alumina insulater in solid Na/S battery system. The harmful effect not only exists in the material when calcium ions are doped before sintering, but exists when the pure sintered sample is soaked in the molten solution(CaCl_2+NaCl), even the content of CaCl_2 is only 0.1 mol%. The mixed additives are concentrated abundantly around the grain boundary and triple grain junction zones. The activation energy of Nat ions will increase to 0.57 eV when the concentration of Ca~(2+) ions is up to 2.0 mol%, and then it will lead the fast ionic conductor to lose its superionic conductibility.

本文叙述了快离子导体Na-β-Al_2O_3长期往复充放电后形成的衰变现象。除通常认为的快速衰变(Ⅰ型衰变)外,还存在一种缓慢衰变(Ⅱ型衰变)。缓慢衰变开始于材料体内的晶界及粒间相,并伴随着电子-离子的重新组合及电子电导等电性能的老化以至机械结构上的破坏。 文中还指出Ca~(2+)是这种用于固体钠/硫电池系统的Na-β-Al_2O_3隔膜的一种十分有害的附加物。它的有害影响不仅在烧结以前掺入材料时存在,当焙烧过的纯净样品浸渍于熔融的(CaCl_2+NaCl)熔液后亦复存在。后者,甚至当CaCl_2含量为0.1mol%时即很明显。引入的附加物亦常富集于晶粒间界及三晶粒交界区域。当Ca~(2+)的浓度增至2.0mol%时,Na~(2+)的激活能将增加到0.57eV,从而导至快离子导体失去它的超离子电导特性。

An accelerated cyclic test for the positive electrode in lead--acid battery has beencarried out for studying the effect of some additives on the behaviour of the positive activematerials. Two mixed additives selected was found to be more effective, with which thecapacity of the active materials was enhanced by 10--15% and the number of the charge-discharge cycles was increased from 19 to 26. The structure and electrochemical properties of the active materials have been investi-gated by the x-ray differaction, scanning electron microscopy and cyclic voltammetric me-asurements.It was shown that addition of cobalt ion increases the content of α-PbO_2,addi-tion of phosphate makes the crystallite of the active materials finer, but addition of silici-de and fibre only partly strengthens the mechanical property of the material. The effect ofPO_4~(3-), Co~(2+) ions on cyclic voltammetry of the lead positive electrode has been discussedas well.

本文采用加速循环寿命手段,研究了几种添加物对铅酸蓄电池正极活性物质容量,及软化脱粉的影响。筛选出两种较好的复合添加物配方,它们可使活性物质的容量提高10—15%,在加速寿命试验中,循环周期从19增加到26。利用x-射线衍射,扫描电镜以及动电位极化曲线法研究了活性物质结构和电化学性能。 结果表明,添加Co~(2+)可增加αPbO_2的含量;添加PO_4~(3-)可使晶粒变细;添加硅化物、纤维只起机械强化作用。本文也讨论了PO_4~(3-),Co~(2+)离子对铅正极动电位极化曲线的影响。
