In order to maximize system energy efficiency(EE) under user quality of service(Qo S) restraints in Long Term Evolution-Advanced(LTE-A) networks,a constrained joint resource optimization allocation scheme is presented,which is NP-hard. Hence,we divide it into three sub-problems to reduce computation complexity,i.e.,the resource block(RB) allocation,the power distribution,and the modulation and coding scheme(MCS) assignment for user codewords. Then an enhanced heuristic approach GAPSO is proposed and is adopted in the RB and power allocation respectively to reduce computational complexity further on. Moreover,a novel MCS allocation scheme is put forward,which could make a good balance between the system reliability and availability under different channel conditions. Simulation results show that the proposed GAPSO could achieve better performance in convergence speed and global optimum searching,and that the joint resource allocation scheme could improve energy efficiency effectively under user Qo S requirements.

Cf/Al composites and TiAl alloy were joined by combustion synthesis in different joining conditions. Effects of additive Cu, joining temperature and holding time on joint microstructure and shear strength were characterized by employing DTA, SEM, EDS, XRD and shear test. Results show that the additive Cu in the Ti-Al-C interlayer could significantly decrease the reaction temperature owing to the emergence of Al--Cu eutectic liquid. Reaction degree of the interlayer was influenced by joining temperature and holding time. Due to the barrier action of formed TiAl3 layer, reaction rate of Ti and Al was determined by the atoms diffusion. The reaction between Ti and AI was more sensitive to the joining temperature rather the holding time. The joints shear strength was influenced by joining condition directly. The maximum shear strength of CS joints was 25.89 MPa at 600 ℃ for 30 rain under 5 MPa. Interface evolution mechanism of the CS joint was analyzed based on the experimental results and phase diagram.

喷雾技术在气体净化、粉尘控制、化学合成等领域应用广泛,其中液滴尺寸控制及提高喷雾均匀性是该技术面临的挑战。为此,本文拟利用表面活性剂对水雾的雾化特性进行调控,以提高喷雾均匀性,并进一步探究其对细颗粒物去除的促进作用。本文采用实验研究,首先对三种不同性质表面活性剂(十二烷基苯磺酸钠、十六烷基三甲基溴化铵、吐温80)溶液的雾化特性进行了分析,探究了表面活性剂的种类和浓度对于雾化特性的影响。结果表明,与去离子水相比,表面活性剂的加入可以显著提升喷雾的均匀性,喷雾总体粒径减小,并且非离子型表面活性剂吐温80雾化形成的小液滴数量占比最高。当表面活性剂溶液浓度达到临界胶束浓度(CMC)时,三种类型表面活性剂溶液的液滴数达到峰值,以此作为最佳雾化浓度。此外,通过喷雾去除细颗粒物实验表明,含表面活性剂溶液喷雾可以加快细颗粒物去除速率。

通过考察不同地区、不同年龄和不同性别受试者唇部皮肤基础状态,进行唇部生理参数的多维度分析和研究,并通过唇油对唇部皮肤的干预,来探究影响唇部皮肤性状的主要因素。用无创性评价方法测定了华东地区(73名)和华北地区(50名)受试者(18~35岁73名,35~60岁50名;男性55名,女性68名)唇部下唇的水分含量、TEWL、光泽度、弹性、L^(*)a^(*)b^(*)值和纹理8个皮肤生理参数。研究结果表明,华东地区组受试者唇部基础状态的经皮水分散失(Trans Epidermal Water Loss,TEWL)值(51.99±17.37)、L*值(51.99±8.83)、b*值(15.40±1.56)和纹理值(15.10±6.43)分别显著高于华北地区组(P<0.05)。35~60岁组受试者唇部基础状态的水分含量(56.82±12.63)和皮肤弹性(0.78±0.18)显著高于18~35岁组(P<0.05)。男性组唇部基础状态的TEWL值(52.08±17.68)显著高于女性组(43.48±16.03)(P<0.05)。通过唇油对唇部皮肤的干预,与基础状态相比,受试者使用唇油后其唇部水分含量均是先降低后逐渐升高;TEWL值先显著性降低后逐渐增加;光泽度、弹性和纹理均是先增加后减小;皮肤色泽(L^(*)a^(*)b^(*)值)的变化不显著。由此可知,受试者唇部皮肤生理参数不仅受到地区、年龄以及性别的影响,还与受试者唇部基础状态及唇部产品的使用频率等因素相关。
