Results In comparison with the controls, the nuclei of many neurons were pyknotic or disappeared, the Nissl substance also showed various degrees of abnormality, and the dendrites were stretched in the high-fluoride and low-iodine groups, and in the high-fluoride plus low-iodine group, espacially in the early developmental stage.

结果 与对照组相比，高氟组和低碘组大鼠大脑皮质及海马内有较多神经元核固缩、核溶解及细胞轮廓不清晰。

There are a few defects in existing processes of biomass gasification, for example using air as gasifying medium, N2 and tar content of the gas is high, and the calorific value is as low as 5000kJ/N in3. The technology of a circulating fluidized bed is still tentative at laboratory level. Through direct pyrolyze biomass, we can get product gas with high heating value (l4000kJINm3), but gas yield ratio is low (O.35m3/kg).

目前的生物质热解气化技术的现状是：以空气为气化剂的气化方式，得到的气体N_2和焦油含量高，热值一般在5000kJ/Nm~3左右；流化床气化工艺操作复杂，推广应用存在较多困难；直接干馏热解，虽气体的热值高（14000kJ/Nm~3），但产气率低（0.35m~3/kg）。

with high development of railage,the axle—temperature of train is quite important for the safety of railage.traditional axle—temperature detected methods can′t match the safe needs of railage.this paper introduces a axle—temperature detect system based on wireless sensor network.this system uses low energy consumption mcu——msp430 and wireless communication module nrf905.it′s placed under the boxcars,form network by wireless communication.it has a high credibility,low cost,extensible and long life cycle.

摘 要：随着铁路高速重载战略的实施，准确地检测列车轴温关系到铁路运输的安全。针对货运列车的特点，分析了传统轴温检测方式存在的各种缺陷，提出了一种基于无线传感器网络的货运列车轴温探测系统的设计方法。该系统采用msp430单片机和nrf905无线通信模块，安装于货车车厢底部，可通过自组织的方式形成网络，具有可靠性高、节点成本低、网络可扩展性好、生存周期长等优点。

Meanwhile, root to shoot ratio of the ramet grown in low light intensity and high nutrient availability significantly increased while that of the ramet grown in high light intensity and low nutrient availability greatly decreased.

深度遮光、低养和高盐均显著削弱金戴戴的生长，其生物量、叶面积、分株数、匍匐茎长及叶柄长和根冠比对基质盐分的可塑性大小和格局显示出基株间的差异。

Tests on road performance of SMA mixture with terylene long fiber and xylon fiber were conducted at both high temperature and low temperature. It was found that the resistances of lignin fiber to asphalt run-off, deflection at high temperature, and water damage were higher than those of terylene long fiber, while the effects of lignin fiber and terylene long fiber on anti-dispersion loss performance and anti-cracking performance at low temperature were basically similar.

通过沥青混合料路用性能试验，研究了涤纶长纤维与木质素纤维对SMA混合料高、低温等路用性质影响，发现同等掺量情况下，木质素纤维对SMA混合料抗析漏性能、抗高温变形性能和抗水损害的贡献好于涤纶长纤维；而二者对混合料的抗飞散损失性能和低温抗裂性能的影响基本相同。

Results:(1) The rats produced amphetamine CPP after treated with 2 mgkg^(-1) amphetamine for 4 days. Ketamine and low, middle, high dose rhynchophylline all could eliminate the CPP effect, and the effect of rhychophylline was increased in a dose-dependent manner. Rhychophylline itself could not induce CPP in normal rats.(2) When compared with normal rats, the NR2B expression in nucleus accubens and amygdaloid of the model rats was obviously increased. Ketamine and middle, high dose rhynchophylline could decrease NR2B expression induced by amphetamine, while low dose rhynchophylline did not affect NR2B expression. Rhynchophylline had no effect on RN2B expression in normal rats.

结果：(1)建立了苯丙胺（2mgkg^(-1)，连续4d）诱导的位置偏爱模型，氯胺酮及钩藤碱低、中、高剂量均可消除苯丙胺诱导的位置偏爱效应，随钩藤碱剂量增加其效应加强，且本身无精神依赖性；(2)苯丙胺模型组大鼠伏核和杏仁核NR2B蛋白表达增加，氯胺酮及钩藤碱中、高剂量抑制NR2B表达，低剂量及本身对NR2B表达无影响。
