The surface of as-prepared LiMn2O4 was modified with ZnO, Al2O3, CoO and LiCoO2 using a simple nitrate melting impregnation method. Transmission electron microscopy （TEM） studies indicated that oxide nano- particles in the range of 10～50 nm are coated on the surface of the spinel. The surface modified samples show better capacity retention than the unmodified LiMn2O4 spinel at both room temperature and 55℃. Among these samples, the ZnO-modified LiMn2O4 shows the best combination of a high capacity and a low capacity fading rate of 0.036% per cycle at room temperature and 0.064% per cycle at 55℃. The improvement for surface modified LiMn2O4 can be attributed to the inhibition of Mn dissolution and O losses on the surface.

This article was to study how TRH receptors in the septal nuclei work inthe analgesic effect and EA analgesia.58 S.D rats were implanted with stainless steel guide tubes into the bilat- eral septal nuclei to provide microinjection, injecting speed 1μl/ 2min. "Zusanli"and "Sanyinjiao" were stimulated bilaterally for ten min, EA parameters were2--15Hz, 2v electric pulses. Using radiant heat teil flick method at 5minintervals for 50min, pain threshold (tail flick latency, TFL) was measured asnociceptive index. The results were as follows:

融合技术接受模型和信息系统成功模型框架,设计了李克特7级量表问卷,探究了不同驾驶场景下驾驶员对生态驾驶诱导辅助系统的使用意愿和对诱导信息的认知偏好。研究表明,驾驶员倾向于接受以语音形式警示非生态驾驶行为的诱导信息类型。在城市道路上,提高诱导辅助系统的感知有用性和感知易用性有助于提高驾驶员对系统的接受度。在城市快速路上,诱导辅助系统的感知有用性和感知易用性仅对高峰场景下的驾驶员使用意愿有显著正向影响,平峰场景下影响驾驶员使用意愿的具体因素仍需在未来诱导实验中深入探究。

It has been shown that analgesic effect caused by EA is related to many neurotransmitters or cAMP in the brain. The aim of this study was to investi-gate whether the analgesic effect of EA antagonized by i.c.v. TRH was relatedto cerebral cAMP.42 female albino rats weighing 180--250g were used in the *** were divided into six groups at random. Bilateral "Zusanli" and "San-yinjiao" of all rats received EA were stimulated. After stimulation with onestrength for 10min, it was stopped and pain threshold (PT) was determinedimmediately by radiant heat-induced tail-flick method. All rats were killed bydecapitation and their brain were quickly removed at 30 min after EA or i.c.v.
