In order to elucidate the effect of the texture, structure and particle size of aggregate on determining its ASR reactivity, the texture, structure and ASR features of zeolitic pearlite and siliceous gravel were examined by optical microscope, XRD and SEM/EDS. It has been found that in addition to the type and amount of reactive constituents in aggregate, the physical structure has also strong influences on the process and expansion behavior of ASR, and the influences of physical structure may be various with particle size of aggregate.

Taken together, our data showed that both the CSF-box and the octamer are important for the LPS-induced G-CSF promoter activity, moreover, the activation of MEK/ERK signaling pathway is indispensible for LPS-induced G-CSF expression in RAW264.7 macrophage.. It seems that LPS-induced activation of MEK/ERK pathway does not directly regulates NF-κB transactivity, but is essential for LPS-induced Oct-2 binding to the octmaer within G-CSF promoter and transcription activation of the G-CSF expression.

透过这些结果，我们认为MEK/ERK pathway的确参与LPS活化G-CSF表现的过程，虽然MEK/ERK pathway都影响了CSF-box以及octamer对G-CSF启动子所贡献的活性，但似乎MEK/ERK pathway的下游并非直接影响NF-κB调控基因转录的活性，而主要是影响了Oct-2对G-CSF启动子的调控。

The effects of soil acidification on the release and leaching of the base ions Al and Si are discussed as well.

METHODS Low-dose Peth 0.01, 0.1 and 1 mgkg^(-1) were given iv 10 min before guinea pigs inhaled 75% cigarette smoke 60 mL. Then, the changes in airway resistance R(subscript aw, dynamic lung compliance C(subscript dyn and vascular permeability in airway tissues were observed. The total leukocyte and the differential leukocyte in bronchoalveolar lavage fluid and nitric oxid e content in BALF were investigated after guinea pigs given iv Peth 0.1 mgkg^(-1) 10 min before cigarette smoke inhalation and consecutively inhaled 360 mL smoke in 2 h.

It is found that the function relationship is affected by initial enrichment, cooling time and burnup range. The function relationship is also affected by irradiation history while the cooling time is shorter than 2 a.

发现幂函数关系中的系数受初始富集度、冷却时间、燃耗范围的影响；如果冷却时间大于2 a，这个关系不受辐照历史的影响；如果冷却时间小于2 a，这个关系受辐照历史的影响。

Thermal characteristics of salty soil are researched by TG-DSC technique. The results show that soluble salts have great influence on thermal characteristics of salty soil; water content gets higher, phenomena gets acuter. Freezing force depends on water content and freezing temperature; the more water content or the less temperature is, the more intensive of freezing force is.

运用TG-DSC技术对冻区盐渍土热特性进行分析并研究环境变化对冻土强度的影响，结果表明：易溶盐对盐渍土热特性有着重要影响，随含水率增大影响愈剧烈；冻结强度随着含水率的增大而增大，随冻结温度的降低而升高。
