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。

From the special viewpoint of information and belief, our analysis finds that through refusing free information the current self can restrain future selves' ill tendency when the external information are static stock. This conclusion can be supported by finite or infinite horizon model as well. When external information are dynamic flow, current self's controlling instrument is forestallment, sometimes he would invest even under negative net present value. Selective memory can also serve as a controlling instrument, current self selectively convey information to future selves.

本文选取了信息与信念这一独特视角，深入探讨现期自我的控制手段，研究发现：当信息为静态的存量时，现期自我可通过拒绝外生信息克制远期自我的不良倾向，该结论在有限期或无限期模型中均成立；当信息为动态流量时，时间不一致矛盾将侵蚀等待的期权价值，现期自我会以抢先行动的方式拒绝进一步信息，甚至采取NPV为负的行动；现期自我也可通过选择性记忆向远期自我传递信息，这就是信息传递阶段的控制手段。

The anatomical study deepens the knowledge of G-type conducting cells: 1 It proves the theory of two depositional process for secondary wall (Bierhorst, 1960): the discontinuous cellulose layer is laid down before the continuous lignified layer; the former layer is prone to be broken down, while the latter is highly decay-resistant; 2 It suggests that the cellulose primary and secondary walls of tracheids are not perforated. Instead of longitudinal pits (Li, 1992), the lignified tracheid secondary wall of Hsüa possesses irregular simple perforations; 3 In Hsüa reflexa and Huia gracilis, the perforation casts may represent the thickness of lignified secondary wall; 4 The wall structure of G-type tracheid is diversified. At the genus level, the secondary wall structure differs in the distribution, internal shape and structure of the perforations; 5 Perforations of some G-type tracheids combine the characters of S-type tracheids in their distribution, density and diameter.

解剖学的研究加深了对G-型输水管胞的认识 1）验证了管胞次生壁分两个阶段形成的理论（Bierhorst，1960），即先后形成不连续的纤维质层和连续的木质化层，前者易被分解，后者抗侵蚀性强；2）证明管胞纤维质的初生壁和次生壁不具穿孔，Hsüa管胞的木质化次生壁具有不规则的简单穿孔，而不是纵列的纹孔（Li，1992）；3）Hsüa reflexa和Huia gracilis的穿孔铸体可代表木质化次生壁的厚度；4）G-型管胞壁层结构具多样性，植物属一级的分异主要表现在次生壁穿孔的分布、孔腔形状和结构的不同；5）某些G-型管胞的穿孔在其分布、密度和孔径方面可兼有S-型管胞的特征。

The toxicity of spent potliner is discussed in this paper according to the research on main constitutes,microstructure,tiny section components,ash content and hydrating reactivity of SPL. The result indicates that the toxicity of SPL mostly rests with its leaching toxicity,contaminates in SPL are mainly dissolving fluorides and cyanides,these contaminates mostly come from electrolyze which infiltrate into the potliner and cause erosion,contents of dissolving F— and CN— in SPL are far more than the permitted discharge in national standard. SPL, which seriously does harm to eco-environment is classified as hazardous solid waste and should be detoxified as soon as possible.

本文从废槽内衬的物相组成、微观形貌、微区成分、灰分、水化反应性五方面研究了废槽内衬的危害性，结果表明，废槽内衬的危害性主要在于其浸出毒性，毒害物质主要是可溶氟化物和氰化物，毒害物质主要来自于电解质对内衬的渗透、侵蚀，废槽内衬中可溶F—和CN—的浓度远远高于国家标准规定的允许排放量，因此废槽内衬被认定为固体危险废弃物，严重危害生态环境，必须进行无害化处理。

However, tracheal stent implantation is different from esophageal stent implantation. As patients with airway obstruction are always complicated by dyspnea and hypoxemia, even respiratory failure, which increases risk and difficulty of stent implantation. During tracheal stent implantation, the bronchofibroscope or stent entering the stenosis site may lead to complete tracheal obstruction-induced asphyxia. Corrosion of metal wire of stent to airway mucosa and vessels may result in hemorrhea, leading to postoperative hemoptysis. Stent dislocation is mainly caused by inappropriate selection of stent, inappropriate implantation position or severe cough. Carcinoma tissue growing along stent lumens can induce re-obstruction in stent, resulting in atelectasis relapse.

气管及食管支架置入均属有创性治疗，但气管支架置入不同于食管支架置入，气管阻塞患者均有不同程度的呼吸困难和低氧血症，甚至发生呼吸衰竭，加大了支架置入的风险和难度；气管支架置入者，当纤支镜或支架进入狭窄部位时可造成气管的完全阻塞引起窒息；支架金属丝对气管黏膜血管的侵蚀可引起大出血，导致术后咯血；支架移位主要由支架选择不当、置入不到位或剧烈咳嗽引起；癌组织沿支架网眼长入造成支架内再阻塞可引起肺不张复发。
