The main environment geological question is: The earth"s crust where the faultage and earthquake are active is unstable; collapse , landslide, mud-rock flow and soil erosion ; The underground karst subsides, seepage question; Basic rock expand, expend and compress soil body, the salt deposit corrode out of shape and groundwater"s corrodent harm; The soft soil question of basin; The soft rock body, cracked rock and the weathering rock are relatively poor stability; High and cold regional highways and railways" frozen soils freeze and melt calamity problem; The around rock of tunnel are unstable because of the coal seam gas, spring water, underground developed area; Project cutting slopes, constructed abandon soil and reservoir, lake"s ecology geological environmental protection issue; Thedangerous shoal of the channel % submerged reef question; The problem of rebuilding channel project and dock etc.; And the problem of unstable ground and groundwater corrosivity during building airport; At the same time, with the international big pathways" implementation and completions of constructions, adjusting the cities and counties" constructions , the crowd occupy changing , the cultivated land distribute changing and the adjustments of structure, will cause local environmental geological issues outstanding; According to multiple statistical analysis , value calculate and integrated appraise result, in the northwest and southwest of Yunnan, the traffic relatively low density, traffic engineering is relatively weak impact on environment, It is the area where a environme
主要的环境地质问题是:活动性断裂、地震带的地壳不稳定;崩塌、滑坡、泥石流及水土流失;地下岩溶塌陷、渗漏问题;基础岩体膨胀、胀缩土体、含盐层侵蚀变形和地下水的腐蚀危害;盆地软土问题;软弱岩体、碎裂、风化岩体稳定性较差;高寒地带公路、铁路建设的冻土冻融灾害问题;煤层瓦斯、涌水、地下采空区等隧道围岩不稳定问题;工程切坡、施工弃土及水库、湖泊生态地质环境保护问题;航道险滩、暗礁问题;渠化工程、码头等库岸再造问题;以及机场建设中的不稳定地基及地下水腐蚀性问题;同时,随着大通道建设的实施和完成,城镇建设的调整、人群居落的变化和耕地分布及结构的调整组合,都可能造成局部环境地质问题的突出等等。经多元统计分析数值计算、综合评价结果,滇西北、滇西南地区交通密度较低,交通工程对环境的影响程度较弱,是环境地质状况好的区域;有主要高原湖泊分布区的,包括昆明、个旧、文山的滇东南区域,环境地质状况较好;大姚、楚雄、篙明及会泽、昭通一镇雄的区域,即滇中北部中生界红层和滇东北岩溶区,环境地质状况中等;而包括保山、德宏、大理、临沧的滇西地区及景东一墨江以东、双柏一石屏一河口以西及东川一寻甸一曲靖地段的滇中一滇东地区,环境地质状况较差。云南国际大通道建设涉及全省区域,如何利用地质环境、实现可持续发展,就必须依赖于国际大通道建设与地质环境之间良性关系的建立。应本着对区域地质环境客观存在的科学认识原则、建设过程中环境效益优先的可持续发展原则、法制性原则、对大通道建设中环境地质的因地制宜及其可防治性原则。并且从组织管理、不同类型大通道、不同环境地质问题类型等方面,提出了对策措施。最后,提出了建立国际大通道建设与环境地质良性关系的宏观建议。

Then I took the Pieces of Cable which I had cut in the Ship, and I laid them in Rows one upon another, within the Circle, between these two Rows of Stakes, up to the Top, placing other Stakes in the In-side, leaning against them, about two Foot and a half high, like a Spurr to a Post, and this Fence was so strong, that neither Man or Beast could get into it or over it: This cost me a great deal of Time and Labour, especially to cut the Piles in the Woods, bring them to the Place, and drive them into the Earth.
然后,我用从船上截下来的那些缆索,沿着半圆形,一层一层地堆放在两排木桩之间,一直堆到顶上,再用一些两英尺半高的木桩插进去支撑住缆索,仿佛柱子上的横茶。这个篱笆十分结实牢固,不管是人还是野兽,都无法冲进来或攀越篱笆爬进来。这项工程,花了我不少时间和劳力,尤其是我得从树林里砍下粗枝做木桩,再运到草地上,又一一把它们打入泥土,这工作尤其费力费时。

Six experimental stages were designed in our procedure, those are:(1) metabolite recovery and tested sample preparation: the metabolites were recovered by Amberlite XAD-2 absorption, followed by MeOH elution and solvent concentration;(2) antioxidant detection and strain selection: samples were quantitatively analyzed by the inhibition effects on formation of lipid peroxides and TBARS to screen the strains able to produce antioxidants. According to the established screening methods, we chose out a strain of actinomycetes, designed as AMBL-029C;(3) antioxidant purification: the fermentation broth was recovered by a series of separation techniques including centrifugation, Amberlite XAD-2 absorption, followed by MeOH elution and a successive TLC purification. The resulting primary purified compound [temperately designed as AMBL-029C-TS] was further analyzed by HPLC to monitor its purity;(4) physical-chemical characteristics: judging from the acid-base fractionation experiments, and the pH and temperature stability tests, the compound was deduced to be a acidic compound with the properties of low polarity and highly pH and temperature stable;(5) mechanism of the antioxidant: in comparison with some other known antioxidants, TS was subjected to investigate its antioxidant mechanism, together with BHT,-tocopherol, as well as two streptomyces metabolites, homogentisic acid and -phenylpyruvic acid, which were previously isolated as the natural antioxidants in our laboratory.
针对本实验目的,我们设计了以下的实验步骤﹔(1)二次代谢物回收及检测样本处理:我们将发酵所得的培养上清液,利用疏水吸附性树酯Amberlite XAD-2吸附回收,并以甲醇溶离及真空减压浓缩脱水等方式处理,以取得提供抗氧化活性筛选之检测样本;(2)抗氧化活性检测及菌种筛选:以「过氧化脂质」和「硫丙二醯尿」的生成量进行定性定量分析以作为抗氧化物质生产菌筛选之用;经此筛选程序,我们选获了具有抗氧化物质高生产力的菌株,命名为AMBL-029C;(3)抗氧化物质的分离纯化:针对生产菌株的发酵回收处理液,以矽胶薄层色层分离法经物质层析纯化后,并以高效能液相层析法(High performance liquid chromatography;HPLC)分析物质可得一初级纯化物质,命名为AMBL-029C-TS;(4)抗氧化物质的物理化学性质分析:由酸碱转溶(acid-base fractionation)实验得知,此抗氧化物质属於中低极性的强酸性物质,对温度(37℃-100℃)及酸碱度(pH3.0-13.0)均表现出高稳定性;(5)在抗氧化机制探讨方面,我们针对数种不同的抗氧化机制进行探讨,即: 1。

Bio-Ba/Ti, bio-Ba /Al were chosen as the sensitive markers to show the variation of the biogenic/terrigenous suspended particles in MNLS through the correlation analysis of 12 major elements of the suspended particles. Comparing with the overlain waters, the content of terrigenous particles in the BNL was increased significantly, but was lower than that in the surface sediment.
与上覆水体相比,近底雾状层内陆源组分显著增加,但较底质沉积物为低;生源组分则明显降低,但比底质沉积物为高,这一规律说明底质沉积物再悬浮对近底雾状层有显著的影响,表明Ba_/Ti和Ba_/Al值可以作为近底雾状层颗粒物的高精度示踪指标,其中Ba_/Al值尤为敏感。

The trees had a light delicate foliage, the structure of which was different from that of the trees in Europe; it did not grow in bows or cupolas, but in horizontal layers, and the formation gave to the tall solitary trees a likeness to the palms, or a heroic and romantic air like full rigged ships with their sails clewed up, and to the edge of a wood a strange appearance as if the whole wood were faintly vibrating.
树木都长着轻巧而细致的枝叶,它们的构造和欧洲树木的结构不同;树冠并非长成弓形或者球型,而是一层一层的生长,让树看起来就像一个个手掌,或者有一种类似升起风帆整装待发的帆船的豪气而浪漫的感觉,森林的边缘也有一种怪异的样子,似乎整个森林都在轻轻摇摆。
