According to core observation and description, many deformation structures with seismite characteristics are recognized within sandstone and shale sedimentary strata of Paleogene continental faulted basin in Yangxin Subsag, such as micro-faults, earthquake fissures, liquefaction sandstone veins, water-escape structure, vibrational liquefaction deformation structure, seismic pillow structure and associated structure, etc. The vertical sequence of seismites in Yangxin Subsag, in ascending order, is underlying unshocked layer, micro-faults layer, autoclastic shattered breccia layer, vibrational liquefaction deformation structure layer, seismic pillow structure and associated structure layer, liquefied homogeneous layer and overlying unshocked layer, which corresponds to different earthquake intensity respectively.

The Orion was a ship that had been ailing for a long time; in the course of its previous cruises thick layers of barnacles had collected on its keel to such a degree as to deprive it of half its speed; it had gone into the dry dock the year before this, in order to have the barnacles scraped off, then it had put to sea again; but this cleaning had affected the bolts of the keel: in the neighborhood of the Balearic Isles the sides had been strained and had opened; and, as the plating in those days was not of sheet iron, the vessel had sprung a leak.

俄里翁号是一条早已有了毛病的船。在它已往的历次航行中，船底上已结聚了层层的介壳，以致它航行的速度降低了一半，去年又曾把它拖出水面，剔除介壳，随后又下海了。但是那次的剔除工作损伤了船底的螺栓。它走到巴利阿里群岛时，船身不得劲，开了裂，由于当时的舱座还没有用铁皮铺底，那条船便进了些水。

The molecular structures of APSP were identified. BAW was selected as the eluent of GC through TLC. After separation and purification, two anthocyanins were obtained.

本文对APSP组分进行了研究，首先通过薄层层析实验选定以BAW体系为柱层析洗脱剂，然后对APSP进行分离纯化，得到两种相对含量较高的组分Ⅰ和Ⅱ，并对组分Ⅰ和Ⅱ进行了一系列结构鉴定实验。

The region within the shell (Figure 3) is called the Brahmanda.

According to the mountain geography, the design use the method of " multiple cancrizans layers " to deal with the horizontal gap, use the enclosing layout to make a big scenery yard in center that make most people in community can enjoy the good sight with the least disturbance, make the transportation, view environment, the flow of people and cars arranged reasonable .

与现场山地地形的结合，以&层层退台&式的设计法处理地形高差，采用建筑围合式布局，以形成中心大尺度景观庭院，使小区主要住宅享有都有较好的景观，令整个小区的交通、景观环境、人流车流等均有较合理的布局，各单体建筑均具较好独立性，各栋建筑之间视线干扰最小化。

These three kinds of Bile extraction were qualitatively detected by using the paper chromatography and infrared spectral scanning method, and the results show that These extractions have the same Rf value and infrared spectra's characteristic absorption peak as choleic acid, glycocholic acid and taurocholic acid standard preparation which can prove that These three kinds of Bile extraction are choleic acid, glycocholic acid and taurocholic acid respectively.

采用薄层层析法和红外光谱扫描法对提取物进行定性检测，结果证明三种提取样品分别与胆酸、甘氨胆酸及牛磺胆酸标准品显色斑点Rf值相同，红外光谱特征吸收峰均一致，表明提取出的三种样品分别为胆酸、甘氨胆酸、牛磺胆酸结晶体。

The free radical scavenging properties of six Aloe species are to be investigated in some modified chemical system. The antioxidant was purified by silica column and thin layer chromatography and analyzed by HPLC. A fraction was purified from A. brevifolia Mill showed the most effective scavenging activities on 〓 and ·OH (66. 01% and 38. 98% respectively). With the analysis of IR spectrum, UV spectrum and mass spectrum, the structure of FA was identifed as 8-C-D-glucopyranosyl-2- [2-hydroxy] propyl-5-methyl-7-hydroxychromone. Its scavenging activity on free radicals is higher than that of aloe-emodin. Its antioxidant activity may be due to the phenoxyl on glucosyl chromone which can be react with free radicals and form relatively stable free radicals.

本研究利用分别产生超氧阴离子自由基和羟自由基的化学模型体系研究比较了不同品种芦荟提取物的清除活性氧自由基的抗氧化作用，进一步利用硅胶柱结合薄层层析法和反相高压液相色谱法，从短叶芦荟叶子中首次分离了具有较强自由基清除能力（超氧阴离子自由基和羟自由基清除率分别为66.01％和38.98％）的成分FA，利用红外光谱、紫外光谱和质谱等仪器分析结果推断出该活性成分的分子结构为8-C-吡喃葡萄糖-2-[2-羟基]-丙基-5-甲基-7-羟基对氧萘酮，它的自由基清除能力高于芦荟大黄素，是一种天然抗氧化剂。

Chromophoric cyclic polyenes including 4H-pyrans, fulvenes, and siloles are designed and synthesized.
