But because of their tubular product defect, easy to produce and corrode, get rusty, marry dirt, leaks and all disadvantage of filling etc.s in using because of zinc-plated steel tube, Thus cause serious two pollution to water quality, microcosmic show as water sample large intestine liver fungus and total amount of bacteria exceed standard seriously, The phenomena, such as" yellow water"," black water"," red water",etc. appear on the macroscopic, water quality worsens; Because corrosion seepage has destroyed users inhabitting and working environment on the other hand, Interfere normal life , influence life quality of people , cause water resource enormous to waste, This require one new-type green one substitute products of environmental protection appear urgently.

但由于镀锌钢管因其管材自身的缺陷，在使用中易产生腐蚀、生锈、结垢、泄漏及诸塞等弊病，从而对水质造成严重的二次污染，微观上表现为水样大肠肝菌及细菌总数严重超标，宏观上出现"黄水"、"黑水"、"红水"等现象，水质恶化；另一方面因锈蚀渗漏破坏了用户的居住及工作环境，干扰正常生活，影响人们的生活质量，并导致水资源的巨大浪费，这就迫切要求一种新型的绿色环保的替代产品出现。

During the course of the well-known "new mathematics" campaign, the status of Euclidean geometry was completely overthrown in I960" s. After deeply thought of "new mathematics", the standpoint that geometry curriculum should reflect the content and method of modern geometry and be in touch with the student" s real life was agreed on. Other countries have tried some significant attempts. We can find from some geometry textbooks that the methods of transform and vector have appeared as a normal part. Simultaneous, not only the new developments of geometry such as Topology have been referred , but also the connection between geometry and practice has been strengthened.In China, geometry curriculum is also in the during of innovation.

而学校几何课程在二千年的时间里一直没有多大的变化，直到二十世纪初"克莱因—培利运动"的第一次冲击，到60年代"新数学"运动的全盘改革，以及之后的深入反思，中学几何课程要反映现代几何学的内容和方法以及紧密联系于实践的观点已经受到普遍的重视，国外的几何课程已经在这方面做了不少有意义的尝试，从国外的一些几何教材中可以发现：变换、向量等工具已经作为正式的内容进入几何教学，拓扑学等几何的新发展也开始在教材中有所体现；几何课程与实践之间的联系更是在很大程度上得以加强。

The main results can beexpressed as follows:(1)Based on πtheory, some affected factors about wave forces are given, and therelation between affected factors and wave forces is analysised by experimentalresults.(2) The distribution of wave press at representative time and reflection nature aregiven and their variety charactes are discussed by experimental results.(3)By comparing the wave forces of quarter-circular breakwater and semi-circularbreakwater under the same wave conditions,some approximately wave forcesexpressions of quarter-circular breakwater are given.(4)Based on VOF method to trace water free surface,solve numerical value ofRANS equation,and get the distributions of flow field and wave press ofquarter-circular breakwater at the same time during one period,the mechanism ofwave force is also discussed elementarily.(5) Based on the result that RANS equation of numerical simulation agree wellwith experimental results,a new approach to study hydraulic natures of quarter-circular breakwater is provided.

其主要结论如下：一、通过π定理，确定影响波浪力的无因次参变量，根据试验结果对其影响因素进行分析；二、基于模型试验，给出典型时刻圆弧面防波堤的同步波压分布和反射特性，讨论它们的变化特点；三、通过相同条件下圆弧面防波堤与半圆型防波堤两种堤型试验波浪力的比较，给出了圆弧面防波堤波浪力的近似方法；四、利用VOF法追踪自由水面，数值求解RANS方程，得到圆弧堤堤体周围的流场和压力场，初步分析了速度涡流与压力场的相互影响；五、对比数值分析与试验结果，探讨数值方法研究圆弧面防波堤水力特性的可行性，提供新的研究途径

Leifeng Pagoda was first built in Northern Song Dynasty 977 AD, two years of peace and rejuvenating the country, originally for the King of Wu and Yue Feng Qian-shu Tibetan Buddhism as a relic to pray for peace and prosperity Luo Ji-fat built, the original name of Princess tower, tower of brick-wood structure leifeng well-known high tower, and Chinese folk legend of White Snake widespread myth is closely related to the story in the embodiment of white snake Bai Suzhen have been a result of the pursuit of true feelings and sea monk imprisoned in Leifeng Pagoda, the Leifeng Pagoda and therefore the statement of history far and wide Leifeng Pagoda on the fire hit twice, the first declared in the Northern Song Dynasty and years, because of Fang La uprising, a torch outside the wooden structure burned to the tower to the Southern Song Dynasty years, have been rebuilt Leifeng Pagoda, West Lake, one of Dusk is the leifeng circulated Leifeng Pagoda at that time subjected to fire the second Jiajing in the Ming Dynasty, when the pirates violation of Hangzhou, Leifeng Pagoda burnt again, remaining tower stands on the shore of West Lake, this case continued until the end of the Qing, Leifeng Pagoda finally collapsed due to overwhelming cause of the collapse on the Leifeng Pagoda in history is also very controversial, in general there are two versions of the previous two years in the clean-up sites Leifeng Pagoda time, found that a considerable portion of the tower of brick side of a small hole in the cave there are Buddhist in the past, people have incorrectly relay erroneous messages will pass into a gold brick by brick, the tower blocks have take-home, resulting in the collapse of the tower argument argument, one of the two, due south is the land of plenty since ancient times, but Hangzhou is the House of silk and tea, the history of Hangzhou on the rich silk, and every year when the silkworms cocoon silk, a variety of reasons, tend to have a large number of cocoon death, Over the past superstition, misconception that cocoon cursed, while the Leifeng Pagoda is a town of white snake demon, thinking that would be the Pagoda bricks at home, they can withstand the erosion of Yao Xie, you have to take a sericulture, his family wealth take a course of time, in particular, Taki shaft damage due to the common people, coupled with those in power are indifferent Leifeng Pagoda finally at 13:40 on September 25, 1924 came crashing down

雷峰塔初建于北宋太平兴国二年公元977年，原本为吴越国王钱淑为奉藏佛螺髻发舍利子以祈祷国泰民安所建，原名叫皇妃塔，塔为砖木结构雷峰塔的知名度之高，与中国民间广泛流传的神话传说白蛇传密切相关，故事中白蛇的化身白素贞因追求人间真情而被法海和尚囚禁于雷峰塔下，雷峰塔因而声明远播历史上的雷峰塔曾两次遭遇大火，第一次是在北宋宣和年间，因方腊起义，一把火把外面的木结构塔身加以焚毁到了南宋年间，曾重修雷峰塔，西湖十景之一的雷峰夕照就是在那个时候流传的雷峰塔第二次遭受火烧是在明朝的嘉靖年间，当时倭寇侵犯杭州，雷峰塔再次把火焚，仅剩塔身屹立于西湖之滨这种情形一直持续到清末民初，雷峰塔终因不堪重负而倒塌了关于雷峰塔倒塌的原因，历史上也很有争论，一般来讲有两种说法，前两年在清理雷峰塔遗址的时候，发现有相当一部分的塔砖一侧有一个小洞，在洞里有佛经而在过去，老百姓们以讹传讹将经砖传成金砖，纷纷将塔砖拿回家，从而导致塔的倒塌此说法之一说法之二，由于江南自古就是鱼米之乡，而杭州又是丝茶之府，历史上的杭州就盛产丝绸，而每年蚕宝宝吐丝结茧之时由于多种原因，往往有大量的蚕茧死亡，过去的人迷信，误以为蚕茧中了邪，而雷峰塔是镇妖的白蛇，以为将雷峰塔的砖放在家里，就可以抵挡妖邪的侵蚀，你家养蚕拿一块，他家求财拿一块，久而久之，塔身特别是塔基由于老百姓的破坏，加上当权者的漠不关心，雷峰塔终于在1924年9月25日下午1点40分轰然倒塌

Mr. I and plans for half a year want a BB but have not been pregnant this month to the hospital for an examination has been found pregnant as a result of six months but were not pregnant so there is no care to protect their early physical illness is as follows吃了药specific menstruation is the last time I was on the 4th to January 2 (can not recall the specific date that the last two days anyway) cycle for 29-32 days as a result of Kim Jong-January 16 Doctor hospital was opened two days of ofloxacin吊针two bottles a day and oral inflammation hundred net service for three days or not some of the symptoms also had oral Lowe four days after 28 No. Because when cooking large half fingernails cut off after two days due to inflammation of eating cefradine BB always wanted as a result of another failed as Friend introduction has been gradually taking ginseng cream until February 3鹿胎feeling some discomfort to the hospital post-mortem examination urine was very weakly positive on the drug problem at that time ask the director of hospital doctors when she helped me just as long as the operator told me to eat before February 5 in medicine are not all right to ask whether she was in the comfort me?
