The advantages of blue InGaN light-emitting diodes （LED） with the active region of gradually increased barrier heights from n- to p-layers are studied. The energy band diagram, hole concentration, electrostatic field near the electron blocking layer （EBL）, and the internal quantum efficiency （IQE） are investigated by Crosslight simulation program. The simulation results show that the structure with gradually increased barrier heights has better performance over the equal one, which can be attributed to the mitigated polarization effect near the interface of the last barrier/EBL due to less interface polarization charges. Moreover, reduced barrier height toward the n-layers is beneficial for holes injection and transportation in the active region. As a result, holes are injected into the active region more efficiently and distributed uniformly in the quantum wells, with which both the IQE and the total lighting power are increased. Although it can lead to the broadening of the spontaneous emission spectrum, the increase is slight such that it has little effect on the application in solid-state lighting.

An AR(1) model with ARCH(1) error structure is known as the first-order double autoregressive (DAR(1)) model. In this paper, a conditional likelihood based method is proposed to obtain inference for the two scalar parameters of interest of the DAR(1) model. Theoretically, the proposed method has rate of convergence O(n-3/2). Applying the proposed method to a real-life data set shows that the results obtained by the proposed method can be quite different from the results obtained by the existing methods. Results from Monte Carlo simulation studies illustrate the supreme accuracy of the proposed method even when the sample size is small.

采用新型一体化脱硫工艺和循环流化床烟气脱硫工艺的脱硫灰为吸附剂,使用固定床反应器,在模拟烟气的条件下研究了两种半干法脱硫灰对汞的吸附及催化氧化特性。研究结果表明,吸附于脱硫灰表面的汞主要以Hg2+的形态存在,多数情况下,更高的汞氧化率伴随有更高的汞吸附率,HCl、Cl2、NO2在脱硫灰的催化作用下能有效氧化Hg0,且不同组分对Hg0的氧化作用可以累积,而NO和SO2抑制了脱硫灰对汞的吸附。脱硫灰中未燃尽碳和Fe2O3对脱硫灰吸附和催化氧化气态汞具有显著促进作用。汞吸附率和氧化率在使用两种脱硫灰作为吸附剂时均随温度升高先增大后减小,这是传质过程和反应速率共同作用的结果。
