Five of their single crystals were obtained and their structures were determined by X-ray diffraction. By comparison, it was found that dithiocabamate complexes often formed an exactly planar MS4 unit, such as [Mo(R2dtc)2]; and also formed a special MS 5 unit, such as [Cu2(R2dtc)4], the copper atom lies in a distorted square-pyramidal environment.Four kinds of heteropoly acids were prepared and characterized; a series of solid superacid catalyst of supported heteropoly acid were prepared and characterized; regioselectivites of chlorobenzene mononitration with nitric acid with different heteropoly acid on different supports and reaction conditions have been investigated.

培养并解析了5个该类配合物的单晶结构，通过比较，发现二硫代氨基甲酸盐与过渡金属容易形成四配位结构，金属原子与4个硫原子共平面，比如二乙基二硫代氨基甲酸钼；也能形成比较特殊的五配位结构，比如二乙基二硫代氨基甲酸双核铜，Cu原子与5个S原子相连，处于一个变形的四方锥结构的配位环境。

Methods:Based on the principle of finite element method and getting three-dimensional coordinates from lateral and frontal cephalometric X-ray films by Baunrind,the landmarks on cephalometric X-ray films were selected as nodes,by which the hard tissue was divided into four noded and pyramidal elements according to anatomic structures and their relationship.

基于有限元分析和Baunrind用头颅正、侧位定位片获取标志点三维坐标的原理，以硬组织标志点作为节点，按照解剖结构及结构间关系对硬组织进行单元划分。

Amongst these, 26 had symptoms compatible with spinal cord involvement. However, two cases with primary progressive pyramidal paraparesis were excluded because after the diagnostic work-up they were found out to have other possible underlying causes (one had constrictive meningeal thickening because of a very remote subarachnoid haemorrhage, and the other had positive family history suggesting an autosomal dominant disorder).

其中，26例有脊髓受累症状，但其中有2例表现为原发进展性痉挛性截瘫的患者，其症状可以用白塞病以外的其他原因来解释，因此，这2例患者被排除在本研究之外（1例患者因蛛网膜下腔出血而出现脑膜增厚，另1例患者因有阳性家族史而怀疑为常染色体显性遗传性疾病--遗传性痉挛性截瘫）。

RESULTS: The layer of CA1 pyramidal cells in both AO groups became thinner with pyknotic nuclei than control.

结果：与对照组相比，各氯化铝组均可见海马CA1区细胞层变薄伴明显核固缩。

In the stratum pyramidale of AD hippocampus, the puncta of synapsinⅠwere larger in size, surrounding both pyramidal cells and pretangles.

以上结果表明晚期AD患者海马synapsinⅠ仅表现为选择性区域性丢失。

Var. pyramidalis is not positively correlated with ion concentration in growth environment, the capacity of selective absorption and transport of ions in Populus alba L. var. pyramidali under salt stress in drainage canal is higher than Populus alba L. var. pyramidal is of normal growth in irrigation canal. Under salt stress, the concentration of K(superscript +)、Na(superscript +) of roots and leave of Populus alba L. var. pyramidalis have changed, the concentration of K(superscript +) of roots and leave dropt the concentration of Na(superscript +) of roots markedly increased, the concentration of Ca(superscript 2+), Mg(superscript 2+) have slightly changed, the concentration of Ca(superscript 2+) of roots dropted, the concentration of Mg(superscript 2+) increased, the concentration of Ca(superscript 2+), Mg(superscript 2+) of leave increased.

主要结论为：新疆杨各器官的离子含量与生长环境中的离子浓度不存在正相关趋势；排渠盐胁迫下生长的新疆杨对离子选择吸收和运输的能力高于灌渠正常生长的新疆杨；盐胁迫下，新疆杨根和叶中K、Na的浓度发生了明显的变化，K浓度在根和叶中呈下降趋势，Na浓度在根中明显增加，根和叶中Ca(上标 2+)、Mg(上标 2+)浓度的变化趋势略缓，根中Ca(上标 2+)浓度下降，Mg(上标 2+)浓度增加，叶中Ca(上标 2+)、Mg(上标 2+)浓度有所上升。

结果发现，Mg2+浓度的提高虽可抑制正常的突触传递，但对LFS诱发LTD并无影响，A-PS的降低幅度仍显著大于S-EPSP。

The secrection of the pyramidal secretory cells is ejected into the spermathecal cavity through secretory canals. The preliminary histochemical stainings shows that the secretion is a kind of glycoprotein and probably plays an important role in storing sperms.
