Liverpool have a Midlands double-header after Christmas, hosting Wolves on Boxing Day before travelling to Villa just two days later. Although it could be much worse during a congested part of the football calendar, the fixture compilers have been kinder to both United (Hull away on the 26th, Wigan at home on the 28th) and Chelsea (Birmingham away on the 26th, Fulham at home on the 28th). Villa Park has been something of a happy hunting ground for Liverpool in recent years, though. It was 1998 when the Reds last tasted defeat there, after two Collymore goals completed a comeback for the home side who had gone behind to an early Michael Owen penalty. Since then, though, Liverpool are undefeated at Villa's ground, winning six and drawing five of their last 11 visits.

但是利物浦在圣诞节后,有两场重头戏现在节礼日做客狼队,然后两天后飞往维拉,相对于曼联(26号客场胡尔城,主场28号维甘)和切尔西(客场26号伯明翰和28号主场富勒姆),利物浦的赛程要糟糕得多,最近几年维拉公园总是利物浦得分天堂,尽管1998年利物浦1比2在维拉饮恨,当欧文点球首开纪录后,柯利莫尔的两粒进球帮助维拉取得胜利,自那时起,利物浦在维拉未尝败绩,他们在11场做客维拉的比赛中6胜5平。

Main creative points of the thesis are as following:1. It is the first time to apply 2-D and 3-D turbulent model of the air-water two phases flow to the study on hydraulic properties of groyne. It makes description of the turbulent flow field to be possible precisely. This offers a more accurate method to determine the water surface in channel improvement.2. Based on the results of experiment and simulation for 3-D turbulent model of air-water two phases flow, a new formula to compute the height of damming is built.3. Based on the 2-D mode and the formula to compute the height of damming, the subdivision method of 2-D computation for water surface at upstream and downstream.

The book said:"gossip Yang Yao '-' and Yin Yao '--' 3 overlap in the form of something to 'number of days''days of the system' has the meaning" and cited "days Sanko, Sun Moon Star"( Ban Gu,"Bai Hu Tong · Feng Gong Hou") certificates. This argument is also wrong: the ancient's "days" refers to an astronomical count one and not confined to Sun Moon Star Sanko.
