  1. 423 persons answered the questionnaires and 139 out of them were identified as ecotourists. the result of classification is proved to be effective by prediction validity test, content validity test, theory validity test and convergence validity test. in addition, the ecotourists were classified as hard ecotourists, frequent ecotourists and occasional ecotourists farther according to the times they traveled to nature - based destinations every year and their new ecological paradigm grade which is used to evaluate the visitors attitude to environment. frequent ecotourists and occasional ecotourists both fall category of soft ecotourists, so the " hard - soft " classification system is founded, which will help propel ecotourist studies in china to develop towards the current international mainstream of the field

    以北京市百花山自然保護區為例，在總結國外相關研究經驗的基礎上，採用k階最近鄰knn和反向傳播bp前饋型多層神經網路所構成的綜合分類器對百花山遊客中的生態旅遊者進行識別，又根據「每年去相對原始的自然區域的旅遊次數」和環境態度尺度nep得分兩項指標將生態旅遊者進一步細分為嚴格的生態旅遊者經常的生態旅遊者和偶爾的生態旅遊者，其中經常的生態旅遊者和偶爾的生態旅遊者歸為一般的生態旅遊者，從而構建起嚴格的一般的生態旅遊者分類體系。
  2. Based on the study on ree distribution characteristics of sinian low grade metamorphic rocks of the basement and cover volcanics, the author makes a discussion on the material source and the genesis of xiangshan volcanics, and suggests that xiangshan volcanics came mostly from the remelting of the upper crust, and the genesis should be attributed to the category of remelted granites

    摘要本文通過對相山火山盆地基底震旦系淺變質巖、蓋層火山巖稀土元素分佈特徵的研究，探討相山火山巖的物質來源及巖石成因，認為相山火山巖主要是上部地殼重熔的產物，其巖石成因應屬于重熔型花崗巖的?疇。
  3. The explosion grade of combustible gas in the environment shall not be more than category

    2適用於環境可燃性氣體或易燃氣體的爆炸等級不高於類
  4. 2. the explosion grade of combustible gas in the environment no more than category ii b, the self - combustible

    2環境中可燃性氣體或易燃氣體的蒸汽爆等級不高於b類。
  5. So, we can draw some conclusions as follows : the method of upgrading the seismic - measures which is adopted by gb50223 - 95 is effective and is more effective than the method of upgrading the earthquake - design - level for those category frames of which seismic - measures are needed to be upgraded from grade 2 to grade 1. but for those category frames of which seismic - measures are not upgraded from grade 2 to grade 1 ( e. g. those frame of which seismic - measures are needed to be upgraded from grade 3 to grade 2 or from grade 4 to grade 3 ), whether the method of upgrading seismic - measure is more effective than the method of upgrading earthquake - design - level needs further research

    因而可以有如下結論， gb50223 - 95對乙類建築所採用的提高抗震措施等級的設計思路是有效的，並且，對于抗震措施需從二級提高到一級的乙類建築，該方法比提高設計地震力的方法更為有效；但對于抗震措施不是從二級提高到一級（如從三級提高到二級、或從四級提高到三級）的乙類建築，提高抗震措施等級的方法是否一定比提高設計地震力的方法更有效尚需作進一步探討。
  6. Shanghai great world international travel service was found in 1982. we are one of the highest grade travel services in china - category a travel service. and we are also the category a air ticket agency

    上海大世界國際旅遊公司建立於1982年，是中國最高等級的旅行社-國家一類社-之一，同時，我公司還是國家航空客運一類代理商，並有權自組中國遊客出境旅遊。
  7. So, the method, that is, determining adjusting coefficient of moment capacity of column - to - beam according to actual reinforcement of beam, which have been adopted by framework of gradel intensity - category 8 and of grade 1 intensity - category 9 can effectively form advantageous energy - dissipation mechanism under intermediate earthquake and rare earthquake

    因此， 9度一級和8度一級框架按梁端實配鋼筋確定樑柱抗彎承載力級差系數的方法能較為有效的引導框架在中震及大震下形成有利的耗能機構。
  8. The main task of the thesis is to judge availability of corresponding seismic measures after code revise through processing inelastic dynamic analysis with the method of multi - waves import for these framework of grade 1 and 2 intensity - category 8 and of grade 1 intensity - category 9 designed in terms of the revised criterions of gb 50011 - 2001 and gb 50010 - 2002. the results show that over - reinforcement of beam because of detailing is the most important reason disturbing framework from forming effective energy - dissipation mechanism

    本文的主要任務是嚴格按修訂后的規范gb50011 - 2001和gb50010 - 2002設計8度一級、二級框架和9度一級框架，通過多波輸入（每個結構輸入5條天然波和一條人工波）對所設計框架做非線性動力反應分析，然後按結構的反應結果檢驗抗震設計措施加強后的結構抗震性能，由此對修訂后規范相應措施的有效性做出一定的評判。
  9. Grade is “ a category or rank given to cntities having the same functional use but different requirements for quality ”

    等級是「對功能用途相同但質量要求不同的實體所作的分類和排序」 。
