In 1917, prompted by a filibuster against Woodrow Wilson's wish to take America into the first world war, the Senate adopted Rule XXII, which said that it could move to cloture if two-thirds of senators present voted for it.

在一九一七年，由于这种filibuster的手段挡下了Woodrow Wilson这位参议员当时希望美国参战一次世界大战的提议，因而刺激了参议院来采用了第二十二号规则，这规则规定如果三分之二出席的参议员同意，可以对辩论做终结。

On July 12th of 2007, the 12th founding anniversary of Hangzhou Diamond Real Estate Co., Ltd, the company cooperated with Hangzhou Wushu Association Marco Polo training field to hold the activity of "get together in Diamond welcome olympics people walk vigorously" to celebrate the birthday of Diamond Company and to wish beforehand the success of Olympics.

二00一年七月十二日，那是杭州达盟物业有限公司成立六周年的庆祝日，是国际奥委会为2008年奥运主办国投票日，也是北京为申奥做最后冲刺的关键时刻。达盟公司组织策划了由社会各界人士六百多人共同参加的登宝石山申奥签名活动，为中国申奥加油助威。活动举行得非常成功，成为杭城在奥运主办权投票表决前一天最大规模的一次申奥签名活动。

Tips: In sharp contrast to other plants, the bamboo only blossoms every 60 to 80 years, and perishes soon after. It takes one to three decades for its seeds to grow. In the past 3 million years bamboos have undergone more than 50,000 extensive blooms. Pandas survived by migrating, but this is no longer an option owing to the sharp decrease of bamboo forests. The last two bloomings of bamboo caused 250 giant pandas to starve to death

小提示：和其它植物相比，竹子每60－80年才开一次花，而且很快就凋谢，从种子长成竹子需要10－30年，在过去的300万年之间竹子经过了5万次的花开花谢，熊猫通过迁移生活了下来，但是由于竹林的减少，在最近的竹子的二个生长期内熊猫的数量减少了250只。

The main contents are as follows:Firstly, starting with the general situation of soil erosion and the harms caused by it, the causes leading to the local soil erosion problem are analyzed comprehensively in the paper. And connecting with the measures taking place, sticking points towards the career of soil and water conservation are expatiated upon.Secondly, Back-Propagation Neural Network, One of Artificial Neural Network is used to set up a modal about the connection of the soil erosion modulus and seven factors impacts on it, such as, rainfall, rainfall largest intensity in 30 minutes, runoff coefficient, vegetation cover percent, rate of granule, rate of physical viscidity-clay, the rate of organic matter. Through the comparison with linear regression model, the second regression model, the Chinese Soil Loss Equation, it illustrated that BP Neural Network modal is more accurate than the other three modals in forecasting the mount of soil erosion, and the BP Neural Network will have some applicability in forecasting in soil erosion.

本文以霍山县作为皖西大别山区的典型区域，主要研究了以下内容：(1)从介绍霍山县土壤侵蚀状况以及所造成的危害入手，全面分析了导致当地土壤侵蚀发生的原因，并结合当地采取的水土保持相关措施，阐述了当地水土保持工作的症结所在；(2)结合上土市水土保持试验站多年实测资料和2005年实验资料，应用BP神经网络理论，建立了次降雨土壤侵蚀量与次降雨量、最大30min雨强、径流系数、植被覆盖度等因子之间关系的模型，并通过BP神经网络的预测模型与一次回归模型、二次回归模型、CSLE模型之间的对比分析，说明了建立的BP神经网络模型在土壤侵蚀预测可以取得较回归模型和CSLE模型更高的精度，也说明了BP神经网络理论在土壤侵蚀预报中具有一定的适用性。

Z XII (Z 12)十二（ 12 ） December 14 , 191412月14日, 1914年 11 attacks in northern France and at the eastern front, dropping 20,000 kg bombs; By the summer of 1915 the LZ 12 had dropped around 9 tons of bombs on the trunk railway line between Warsaw and Petrograd and the stations at Malkin and Bialystok ; one flight carried a load of 3 tons.

11日袭击法国北部和东部阵线，下降二点〇〇〇万公斤炸弹；到1915年夏天的川芎嗪12日已下降约9吨炸弹的主干铁路线之间的华沙和彼得格勒和站金和比亚韦斯托克；一次飞行进行负载3吨。

In 1968 extensive research on direct potable reuse was conducted in Windhoek, Namibia.

自1960年以来，迫于调整压力和水的缺乏，一份深入的调查结果给水再利用工程的健康风险和治疗系统提供了有价值的洞察力。1965年，以色列健康部门出版章程允许对农作物灌溉实行二次污水再利用，还有被排除在外的不用煮可以吃的蔬菜作物。1968年在温得和克和纳米比亚对直接可饮用的再利用进行了广泛的研究。1972年在美国，有一件重要事件就是通过了联邦水污染控制法案（PL92－500）&修复并且维持民族水资源的化学，物理和生物的完整性。&

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
