The aerosol number concentration and size distribution were measured with the newly developed Wide-range Particle Spectrometer in summer and winter of 2006 at the urban site of Jinan City. Here reported the characteristics of fine particles of the different observation seasons. Relative high number concentrations for the particles in the diameter range of 10-500 nm were observed in both seasons. It was found that the dominant number distributed in particle diameter smaller than 100 nm and the percentage over the number concentration of all air particles is much higher than what has been measured in other urban sites over the world. The number mean diameter in summer was much smaller than in winter, strongly suggesting the different origin of ultrafine particles in different seasons. That is, particles in ultrafine mode mainly came from nucleation and new particle formation in summer while from traffic emission in winter. The diurnal variation also supported this point. Number concentration in the diameter range of 10-200 um got their peak values at noontime, well correlated with the mixing ratio of SO2 and the intensity of solar radiation in summer. While in winter, those in the same diameter range showed the main peaks during the traffic hours happened in the morning and evening.

Polymeric microwave actuators combining tissue-like softness with programmablemicrowave-responsive deformation hold great promise for mobile intelligentdevices and bionic soft robots. However, their application is challenged by restricted electromagneticsensitivity and intricate sensing coupling. In this study, a sensitized polymericmicrowave actuator is fabricated by hybridizing a liquid crystal polymer with Ti3C2Tx(MXene). Compared to the initial counterpart, the hybrid polymer exhibits unique spacechargepolarization and interfacial polarization, resulting in significant improvements of230% in the dielectric loss factor and 830% in the apparent efficiency of electromagneticenergy harvest. The sensitized microwave actuation demonstrates as the shortenedresponse time of nearly 10 s, which is merely 13% of that for the initial shape memory polymer. Moreover, the ultra-low content of MXene (upto 0.15 wt%) benefits for maintaining the actuation potential of the hybrid polymer. An innovative self-powered sensing prototype that combinesdriving and piezoelectric polymers is developed, which generates real-time electric potential feedback (open-circuit potential of ~ 3 mV) duringactuation. The polarization-dominant energy conversion mechanism observed in the MXene-polymer hybrid structure furnishes a new approachfor developing efficient electromagnetic dissipative structures and shows potential for advancing polymeric electromagnetic intelligent devices.

民用燃气加臭是安全供气的必要措施,我国《城镇燃气设计规范》(GB50028-2006)中明确规定城镇燃气应进行加臭。民用燃气加臭工艺技术在西南地区运用尚不十分广泛。针对重庆市万盛、南川两地民用燃气加臭装置,从选型及运行状况等方面着手,通过对加臭装置手动及自动加注量、加注浓度的对比分析,发现现有民用燃气加臭装置手动加注中存在的加注量过大、浓度不稳定等不足,提出手动加臭程序分时段设定的改进建议,以有效地减少手动加注量,减少加臭剂的浪费,降低加臭成本,并对民用燃气加臭装置应用中如何控制好装置选型及自动控制两个关键点进行了探讨,为民用燃气加臭工艺技术的推广应用与改进提供参考。

目的探讨采用改良腰椎后路椎间植骨单侧椎弓根螺钉固定术式在腰椎融合手术中的临床效果,并比较与传统腰椎后路椎间植骨椎弓根螺钉固定术式的术后疗效和并发症。方法随机选取2007年2月至2009年5月行腰椎后路融合手术96例进行回顾性研究,改良术式组(A组)40例,其中男14例,女26例,平均年龄(52.23±9.75)岁;传统术式组56例,其中男22例,女34例,平均年龄(56.02±10.25)岁。比较两组手术ODI评分、VAS评分、手术时间、出血量、住院时间、住院费用、植骨融合率、椎间隙高度等多项指标。结果两组术式术后短期ODI、VAS评分、椎间隙高度变化无明显差异。改良术式组较传统术式组手术时间短、出血量少、住院费用少(P<0.05)。术后12个月两组植骨融合率均为100%。结论改良腰椎后路椎间植骨单侧椎弓根螺钉固定是一种切实有效的腰椎融合术式,与传统术式相比具有创伤小、风险小和医疗费用少的优点,但远期疗效仍需进一步随访与研究。
