Furthermore, in the CTA rats, compared with water stimulability, FLI neurons of SON and DMV induced by sucrose stimulability had had much more expressions.6 When the same sucrose stimulability was given, FLI neurons expressions of SON, DMV and LH in the CTA rats were much lowwer than that in the control rats.Conclusions:1 CTA had an inhibitory effect on small intestine peristalsis, indicate taste preference has an effect on small intestine peristalsis, and inhibitory effect induced by CTA is corresponded with US, this effect may have relations with vagus efferent never and humoral regulation.2 In the electrophysiology experiment, discharges of vagus efferent never in the CTA rats are much more than that in the control rats, indicates taste and taste preference may regulate small intestine peristalsis via vagus nerve, and dicharge can continude 1 hour, indicate humoral regulation also exists in the regulation.

结论1建立味觉厌恶对小肠运动有抑制作用，提示味觉嗜好性对小肠运动有影响，而且味觉厌恶引起抑制作用是与条件刺激成对应关系的，味觉刺激引起的小肠蠕动的抑制作用可能与迷走神经传出神经及体液调节有关。2在电生理实验中，CTA大鼠迷走神经传出放电高于对照组的大鼠，提示味觉及味觉嗜好性可能是通过迷走神经对小肠运动进行调节的，放电至能持续60min，表明味觉及味觉对小肠运动的调节中还有体液调节的参与。

Computer micro-vision, Mirau microscopic interferometry, stroboscopic photography and laser Doppler vibrator are integrated into this platform. In-plane and out-of-plane periodic motion characteristics of micro-resonator are measured, and out-of-plane transient motion of micro-mirror is analyzed. In-plane displacement, motion phase and resonance frequency can be measured by integrating computer micro-vision with stroboscopic photography, and the repeatable accuracy of in-plane displacement is 30 nm.

实验结果表明，利用计算机微视觉和频闪成像技术能够实现微结构的平面位移、运动相位及谐振频率等周期运动参量的测试，位移的重复精度为30 nm；利用显微干涉和频闪成像技术可实现微结构的离面位移及表面扭曲等周期运动参量的测试，位移的重复精度为3 nm；激光多普勒测振技术具有在频域上对微结构瞬态运动进行分析的优点，是时域上周期运动测试的重要补充。

Blood Pheasan lived in groups in winter In the breeding season the tendency living in groups also existed among non-breeding subadult males, breeding adult males or paired birds.

冬季集群活动。繁殖季节不参加繁殖的亚成体雄鸟、参加繁殖的成体雄鸟或配偶对往往也有集群活动的倾向。

objective: to evaluate the clinical application of helical ct for the location or treatment of maxilla embedded tooth in the dental orthopaedics.method: 18 cases with embedded tooth of maxilla were made with clinical examination, dentomaxillary pantomography, submaxilla lateral projection and helical ct.the operation be done for supernumerary tooth,distorted teeth,inverted tooth.three embedded tooth of non-inverted tooth were done by orthopaedics.result: among the 18 embedded tooth ,there were 11 palatally and 6 labially presented teeth,1 the 18 patients is mediately with completely inverted supernumerary tooth.all preoperative assessment are one and all in operative or orthopaedics and primary wound healing.

四川大学华西口腔医学院正畸科，四川成都 610041摘要：目的：正畸治疗中对上颌埋伏牙如何定性，定位，并要对此是采取手术拔除［1］或者是正畸治疗进行探讨。方法：对18例（其中1例为2颗多生牙，1颗多生牙已长出，另一颗为完全倒置的多生牙），上颌前部埋伏牙采用临床检查以及拍摄全景片、头侧位片螺旋ct轴位和表面成像等检查［2～4］对埋伏的多生牙、畸形牙和倒置牙共15例采用了相应的手术进路拔除，对形态正常且不倒置的3颗埋伏牙采用了正畸治疗。

Methods: Thirtythree patients were reported. Clinical manifestation,imaging findings including the computer tomography, magnetic resonance and digital substruction angiography were analyzed.

对33例椎基底动脉系统脑梗死患者的临床资料进行回顾性分析。1例行CT检查，32例行头颅核磁共振检查。2例行CT血管成像检查，2例行磁共振血管成像检查，4例行脑血管数字减影检查。

Among them,73 genera and 36 families,occupies 80.23% of the total number of the genera and 78.26% of that of the families, were tropically and subtropically distributed genera and families, the other 18 genera and 4 families,merely occupied 19.77% of the total number of the genera and 8.70% of that of the families,were temperately distributed genera and families,which suggested that the variation of the altitude might affect the plant composition of communities in some degree.

热带性成分科、属与温带性成分科、属各有36科、73属和4科、18属，分别占样地种子植物科、属总数的78.26%、80.23%和8.70%、19.77%，表明热带性区系成分在群落中的优势地位，同时一定数量的温带成分的入侵，反映出海拔高度变化在一定程度上对植物区系组成的影响，表明鼎湖山山地常绿阔叶林具有向中亚热带常绿阔叶林过渡的特点。

"Tensor diffusion imaging is a form of MR imaging that the rate and direction of water particles in the white matter structures of the brain," says lead author James Provenzale, MD.

主要作者，Provenzale医师说：「张量扩散成像技术是一种MR成像技术，这种技术可以对脑白质结构中的水颗粒的含量和变化趋势进行『测量』。

In the end of 80s, ABCS has been very popular in America, and it has accumulated experience after years of application, practice, and successes.

有的学者认为，作业成本法在中国将有广泛的应用前景，只是时间迟早问题；另外的学者持保留态度，认为作业成本法尽管对成本的准确性有所帮助，但所花代价太大，在中国企业中不适用。
