To analyze the response of pavement structure under moving loading, a quarter vehicle model with single freedom degree and unevenness model are established. The dynamic loads are calculated through combining different pavement conditions and speed. When the incentive frequency which is passed to vehicles by the road is close to its own vibration frequency, vehicles will produce the greatest dynamic load.

Results:①In normal extracellular solution, the non-selective cholinergic agonist acetylcholine and the muscarinic agonist muscarine both caused the increace of [Ca2+]i in separately 21 out of 25 and 14 out of 18 VHCs I, while only 3 out of 20 and 2 out of 16 VHCs I had a weak increase of [Ca2+]i if investigated in calcium free extracellular solution; nicotine could increase the [Ca2+]i in 7 out of 32 VHCsⅠonly at enough high concentration(up to 10 mmol/L) in normal extracellular solution, this [Ca~(2+)]_i increase by nicotine at high concentration could not be investigated if at calcium free solution.

结果①非选择性胆碱能受体激动剂乙酰胆碱、M型胆碱能受体激动剂毒蕈碱在正常细胞外液中均可引起大部分(21/25， 14/18)单离VHCⅠ[Ca~(2+)]_i的升高，但无钙外液中ACh、muscarine仅使少部分(3/20，2/16)VHCⅠ[Ca~(2+)]_i升高且作用减弱；正常外液中，N型受体激动剂尼古丁仅在高浓度(≥10 mmol/L)时引起部分(7/32) VHCⅠ[Ca~(2+)]_i升高，在低浓度时对胞内钙离子浓度影响不明显，无钙外液中，10 mmol/L nicotine对胞内钙离子浓度影响不明显。

Metallurgy School, UST Beijing, Beijing 100083, China）ABSTRACT The negative thermal expansion in some complex oxides has beenattributed to transverse thermal motion of A-O-M linkage composed of two-coordinate oxygenbridge bond, and the librationsand tilts of essentially rigid polyhedral blocks in openframework structure. The isotopic NTE materials have been finding moresubstantialapplications in composites and other relative technique fields.

氧化物材料负热膨胀机理邢献然摘要氧化物的负热膨胀性是由于在其开放式的骨架结构中，有二配位的桥氧键产生横向热运动，以及引起的多面体热摆动和耦合作用使非键合M-M1键距变短，导致单胞体积缩小；各向同性NTE氧化物在复合材料及其相关技术领域具有更广泛的应用价值。
