The single wheat school and Taiwan school are the largest with lie in that Denmark pays attention to groups discussing very much, it is possible in 40% of the time of school Make groups report of panel discussion, remaining time was not used for having a class , but the school of Denmark quite paid attention to students view on anything In not giving a lesson, teacher will ask student issue constantly, even very much enthusiastical to is it is it say out their idea to make a speech to raise the hand student have, and just opposite in Taiwan We have few panel discussions, have an examination outside having a class, idea say come out us seldom too, compare as if passive study, the school of Denmark has not had uniforms like school of Taiwan either in addition, the reason with the uniform of school of Taiwan is , do not hope that students spend too much time in disguising oneself , they hope that students spend more time on the lessons , I think this is Taiwan with the biggest difference of Danish school.

单麦学校和台湾学校最大的不同就在於丹麦非常注重团体讨论，有可能在学校40%的时间都在作小组讨论小组报告，剩余的时间才用来上课，而丹麦的学校也相当重视学生对任何事情的看法在上课当中，老师会不断问学生问题，学生也很踊跃的举手发言把他们的想法讲出来，而台湾正好相反我们小组讨论很少，上课之外就是考试，也很少把我们想法讲出来，比较像是被动的学习，另外丹麦的学校也没有像台湾学校一样有制服，之所以台湾学校有制服的原因是，不希望学生花太多时间在装扮自己上面，他们希望学生花多一点时间在课业上，我想这是台湾跟丹麦学校最大的不同。这些东西我没有办翻译的很详细很到位所以可以请大家帮我翻译一下吗谢谢唷很感谢

For frequency information fluid identification technology:the basic theory of fluid identification based on frequency information has been introduced,for inner and external factor affecting frequency,some steps have been proposed to attain reserved amplitude and frequency analysis data with high resolution,high S/N ratio;through the comparison of time-frequency analysis method, the high accuracy time-frequency analysis method has been selected to extract time-frequency attributes;the analysis method flow of common single frequency fluid identification has been proposed,according to the data of full frequency band,several anomaly zone modes of common single frequency attribute have segregated; incorporating converted wave and compression wave,fluid identification method based on PS wave combined time-frequency analysis has been proposed;the AVO property of various fluid type in frequency domain has been studied;the generalized fourier analysis method,Proni absorption filter has been introduced,and researched for anti-noise and for the seismic processing interpretation flow.The above technology have been applied to fluid identification of organic reef in WBT area in the east of Sichuan and fluid identification of clastic rock in GUANGAN area in the middle of Sichuan,the results show that the above methods are effective.

另外因为路线转向上方队员就在下方队员斜上方，岩石松动的季节还是有滚石击中队员的可能，垭口上50-100米路段，是整块整块的岩面交错的地带，岩面平均高6-7米，坡度70-80度，很光滑直接攀上太费力不可取，由于雪大看不出好的路线，只有绕着岩面走，在跨越岩面时有部分路段是贴着山脊走，最近的离悬崖仅一米，而且脚下如果结冰或者是硬雪时很容易滑下山脊，比较危险。

Because defends external national the invasion, must need the quite firm fortification or the castle, therefore the ancient babylonian can not but use crops' as well as bushes and so on plant's the straw stalk makes the fuel, makes certain shape the soil to burn the quite solid brick bat to do for the main building material, uses for the building big city wall and the fortress, and displayed the acme, therefore only then north two river basin edge mountainous area, only then appeared certain scale stone system construction, but compared the ancient Egypt's stone system creation on "big Wu Jianxiao" Wu, because the soil burn brick or at that time burns the technical limit, basicIs unable to compare with the hard rock, although the brick uses, extremely nimble and may the rapid construction broad in scale building or the urban cluster, but radically is unable to achieve actually Shi Zhi constructs that kind of altitude as well as in time eternal degree, therefore is called by the historian the world ancient times one of seven wonders of the world "the airborne garden" has become on the ruins historical miracle, now only then also in continues in the decency the remnant brick to break the tile to relate once magnificently with glory, long-time, all vestiges could even more be not much left.

由于防御外来民族的侵扰，必须需要比较坚固的防御工事或者城堡，因此古巴比伦人不得不用农作物以及茅草等等植物的秸秆做燃料，把制成一定形状的泥土烧制成比较结实的砖块来做为主要的建筑材料，用来建筑高大的城墙和堡垒，并发挥到了极致，因此只有在两河流域北部的边缘山区，才出现了一定规模的石制建筑，但相比古埃及的石制创作就&大巫见小巫&了，由于泥土烧制的砖或受当时烧制技术的限制，根本无法与坚硬的岩石相比，虽然砖使用起来，非常灵活并可以迅速的建造规模宏大的建筑物或者城市群，但却根本无法达到石制建筑的那种高度以及在时光中的永恒程度，于是被史学家称为世界古代七大奇迹之一的&空中花园&就成了废墟上的历史奇迹了，如今只有还在继续风化中的残砖断瓦在诉说着曾经的辉煌与荣耀，更长久一点，一切遗迹就会更加的所剩无几了。
