两年一次的

We know that the solutions of quadratic, cubic and quartic can be expressed by radicals. As to the solution of the quintic which has became an issue for past two or three hundred years, it was not solved until 1832 a great young Mathematician of French named Galois who recommended group theory that proved a polynomial of degree 5 and over 5 can't be solvable by radicals.

中文摘要我们知道二次、三次及四次的方程式都可以用根式表示，至於五次方程式的解迟迟无法解决，这个问题持续了两三百年，直到1832年，一位法国青年Galois在其决斗前夕，在他的遗书中，这位伟大的青年数学家引进了群的理论，证明了：五次及五次以上的方程式，不可能有公式解。

Based on the samples of over 1000 listed companies at the beginning of Reform of Non-tradable Shares in 2004 and 2006, the share proportion CR1 of the largest shareholder, Z index calculated as the ratio of share ratio of top 2 shareholders and H10 index calculated as the sum of square of share ratio of top 10 shareholders, and Tobin'Q reflecting the value of target company are sele

本文以股权分置改革开始的前后两年即2004年和2006年的一千多家中国上市公司为研究样本，选取第一大股东持股比例CR1、前两大股东持股比例的比值Z指数以及前十大股东持股比例的平方和H10指数作为衡量大股东控制程度的指标，采取托宾Q值来作为衡量公司价值的指标，把公司规模、财务杠杆和第一大股东性质虚拟变量作为控制变量，建立回归方程，实证结果发现三次？

They meet annually at a Council meeting and triennially at a General Assembly at a location within the Asian Region to, amongst others, network and exchange views and information concerning intellectual property protection in the Region.

协会每年召开一次理事会，每隔两年在亚洲召开一次全体会议，就亚洲和其他地区的知识产权保护问题加强联系、交换意见。

Similar experiments, but using Chemical Release Modules, have been launched from Churchill, Manitoba. In 1980, Brian Whelan's "Project Waterhole" disrupted an aurora borealis, bringing it to a temporary halt. In February 1983, the chemical released into the ionosphere caused an aurora borealis over Churchill. In March 1989, two Black Brant X's and two Nike Orion rockets were launched over Canada, releasing barium at high altitudes and creating artificial clouds.

同样的但是采用化学释放模型的实验，在加拿大马尼托巴的丘吉尔被启动。1980年，布瑞安威兰的"水洞项目"中断了一次北极光，使之暂时停止。1983年2月，排放进电离层的化学物质引发了丘吉尔上空的北极光。1989年3月，两艘"黑雁X"和两艘"耐克奥瑞恩"火箭在加拿大上空被发射，在高纬度释放钡产生人工云。

Ma Yun points out when summary ABAC job: Our mainest 2008 job was to organize peak of medium and small businesses to meet, be in Hangzhou, be in Peruvian, gained huge success twice this.

马云在总结ABAC工作时指出：2008年我们最重要的工作是组织了中小企业峰会，一次在杭州，一次在秘鲁，这两次都取得了巨大的成功。

As for the first, which was so vastly big, as I made it without considering before-hand, as I ought to do, how I should be able to launch it; so never being able to bring it to the Water, or bring the Water to it, I was oblig'd to let it lye where it was, as a Memorandum to teach me to be wiser next Time: Indeed, the next Time, tho' I could not get a Tree proper for it, and in a Place where I could not get the Water to it, at any less Distance, than as I have said, near half a Mile; yet as I saw it was practicable at last, I never gave it over: and though I was near two Years about it, yet I never grutch'd my Labour, in Hopes of having a Boat to go off to Sea at last.

这是由于我事先没有考虑到船造好后的下水问题，而这问题是我应该预先考虑到的。现在，那艘独木舟只能躺在原地留作纪念，教训我下一次应学得聪明些。这一次，我没能找到一棵较合适的树，而且，还需把水从半英里以外引过来。然而，当我看到有成功的希望时，就不愿放弃这一机会。虽然造成这条小舟花了将近两年的时间，我却从未偷懒或厌烦。我一直希望，迟早有一天我能坐上小船到海上去。

I was once draftedby Lyndon Johnson and had to live in shit-ass Mexico for 21/2 yearsfor no reason.

威利：我进过一次监狱，结过两次婚，在林顿·约翰逊的招募下不得不在他妈的墨西哥呆了两年半。

In the 5000 years' history of the Chinese culture there have been only two real cultural revolutions. One is the "proscribing all non Confucian schools of thought and espousing Confucianism as the orthodox state ideology" in the Han dynasty, hoisting the only banner of Confucianism through eliminating the other hundred schools.

纵观五千年的中国文化发展史，真正意义上的文化革命只有两次：一次是汉代的&罢黜百家，独尊儒术&，通过革文化百家之命，树儒学一家之帜，儒家文化从此成为中国文化的主流；另一次就是彻底地把儒学掀翻下马的&五四&运动。

I spent a year dueling for first chair on tenor sax with Larry McDougal, who looked as if he should have played backup for Buddy Holly, the rocker who died tragically in a bad-weather plane crash in 1959 along with two other big stars, the Big Bopper and seventeen-year-old Richie Valens.

有一年时间，我和拉里。麦克道戈尔积极争夺次中音萨克斯管的首席。麦克道戈尔神气的不得了，似乎觉得自己该为摇滚乐手巴迪。霍利伴奏。1959年，在一次气候恶劣的飞行中，霍利不幸机毁人亡，同时遇难的还有另外两位大明星，一位是比格。波帕，一位是17岁的里奇。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
