本文通过对双龙砂金砂床的地貌、沉积物、金的粒度及形态、矿床产出特征的研究,认为该矿床是在中晚更新世及全新世初期的冰川的作用及化学作用下而形成的冰水堆积-阶地型砂金矿床。

The tectonic evolution history of Tianshan is an example. In the Triassic, it was once uplifted to form the mountains with thick molasse accumulation on both its sides, Junggar and Tarim Basins. Then it became a peneplain by the exposion and deplanation in the Jurassic, forming the widespread coal-bearing strata which can be correlated. From the Cretaceous to the Early Cenozoic, it was uplifted again, until the Quaternary to build huge mountains with two large sedimentary basins on both sides.

如天山山脉的构造演化,三叠纪天山曾经一度隆起成山,两侧的准噶尔和塔里木盆地中堆积了巨厚的磨拉石;侏罗纪时由於剥蚀夷平成为一个准平原,形成了广泛分布且可以对比的含煤岩系;从白垩纪到早新生代,它再度隆升,直至第四纪时形成雄伟的高大山系,两侧形成相应的大型沈积盆地。

Since polar organic crystals have noncentric structures, the existence of polar axis in the crystals has a significant effect on the molecular arrangement and on the crystal growth.

极性有机晶体在不同的溶剂中具有明显不同的生长习性,主要有两个方面的原因:一是极性有机晶体属非中心对称性晶类,晶体具有极轴,极轴的存在对分子堆积和晶体生长具有重要影响;另一是极性有机晶体的界面结构不同,溶剂与晶体界面的相互作用不同,使得晶体同一面族的生长速率不同,从而导致了晶体习性的改变。

It will fulfill four scientific objectives, including a three-dimensional survey of the Moon's surface, analysis of the abundance and distribution of elements on lunar surface, an investigation of the characteristics of lunar regolith and the powdery soil layer on the surface, and an exploration of the circumstance between the earth and the moon.

它在月球表面将履行四个科学宗旨,包括元素的月亮的表面、分析对丰盈和发行的一次三维勘测月球风化层的特征的调查和粉状土壤在表面和情况的探险分层堆积在地球和月亮之间。

It is thought that the channel bay line evolution processes can be divided into four stages. The first stage is soon of the sea level stable when the bayhead mountines are eroded and developed abrasion geomorphy and the productive materials were transport into the bay deposition by the tidal current and wave current and were reworked into gravel dams. The second stage is characterized by the fluvial output sediments and eroded sediments mixed deposition in channel bay and developed marine accumulation plain and sand riges in the plain under the wave reworked. The third stage developed clay silt marine accumulation plain under the action of the channel current and the wave action is very limited. The fourth stage is marked by human being reclaim which result in the channel bay filled and evoluted into a strait arce coast.

文章认为,峡道海湾的充填经历了四个阶段,第一阶段以峡道海湾湾顶山体在波浪作用下产生的侵蚀物质充填为主,发育了海蚀崖、海蚀洞、海蚀穴等侵蚀地形和湾顶砂砾石堤等堆积地形交替的峡道湾顶地貌,第二阶段以河流输出物质和峡道湾岛屿、礁石侵蚀物质在潮流作用下向峡道湾输运,由潮流和波流共同沉积为特征,发育海积平原,部分粗颗粒泥沙在波浪的改造峡,发育平原沙堤,第三阶段以河流输出物质为主,在涨落潮流搬运下进入峡道和峡道湾沉积,在峡道湾中发育以淤泥质粉砂为主要物质的海积平原,第四阶段以人类围涂造田为标志,加速峡道湾的充填过程,使峡道海湾最终趋于夷平,形成顺直均衡的弧形海岸。

The Mo center of [Mo8](superscript 4)-shows a slight distorted square antiprism coordination environment. The N atoms of cyano groups, acting as acceptors of hydrogen bonds, together with protonate N atoms from organocations and the lattice water, serving as donors of hydrogen bonds, form intricate hydrogen bond interactions, thus generating three-dimensional supramolecular network with the help of π-π interactions of some organocations.

Results: The changes following hydrocortisone intervention of rats could be identified by PCA, and the kidney deficiency syndrome rats entered a state of "hyperfunction", involving a series of changes in metabolic pathway and metabolic network. The response integral area of lactic acid (δ 1.37) increased, indicating the accumulation of metabolites of lactic acid. The amount of dimethylamine (δ 2.72) also increased, indicating that the disorder of kidney function was related to kidney-deficiency syndrome. The response of creatinine (δ 3.87), asparaginic acid (δ 2.83), taurine (δ 3.44, 3.28), and hippurate (δ 7.84, 7.56, 7.64, 3.97) all decreased significantly, indicating that the hydrocortisone might cause adrenal cortex excretion injury. The response integral area of succinate (δ 2.41) and citric acid (δ 2.53, 2.68) decreased, which was usually caused by disorder of the mitochondrial function.

结果:PCA方法处理肾虚证和空白对照大鼠尿液数据显示,两组大鼠的数据可以在得分图实现分类,与对照组比较肾虚组大鼠由于氢化可的松诱导,大鼠机体进入一个过消耗后衰弱的状态,相关代谢发生显著变化,乳酸(δ 1.37)代谢发生堆积;二甲胺(δ 2.72)的含量增加,提示肾虚与肾功能异常是密切相关的;天冬氨酸(δ 2.83),牛磺酸(δ 3.44, 3.25),马尿酸(δ 7.84, 7.56, 7.64, 3.97),肌氨酸(δ 3.87)等的相对积分面积明显下降,这预示糖皮质激素可能引起了肾上腺皮质分泌功能的损害;琥珀酸(δ 2.41)和柠檬酸(δ 2.53, 2.68)是三羧酸循环能量代谢及糖酵解的中间产物,其含量的降低,通常是由于线粒体功能紊乱所引起。

Concentration of silver behenate solution affects the morphology and packing density of silver. The thin silver film of spherical silver particles, with an average diameter of 160 nm has been fabricated by a millimolar solution of silver behenate. The thick silver film is consisting of the regular silver particles with triangular or truncated triangular shape, which is formed at high concentration.
