遵义会议后，在毛泽东的指挥下，四渡赤水河，穿插于敌人重兵之间，歼灭大量敌人，随后出敌不意南渡乌江，直逼贵阳，抢渡金沙江，摆脱了数十万国民党军的围追堵截，取得了战略转移中具有决定意义的胜利。5月，顺利通过大凉山，强渡大渡河，翻越终年积雪、空气稀薄的夹金山，6月中旬，与同年5月从川陕苏区长征的第四方面军在四川西部懋功地区会师，后因张国焘的反党分裂活动，红一方面军先行北上。

The results show that the air crossing pressure pulse magnitude of the container generated in the tunnel is 3.46 times that generated in open air when container flat wagon at the speed of 160 km/h passed by EMU moving at the same speed. Both the lateral force and overturning moment of the container train during the crossing induced in open air and tunnel are approximately proportional to the square of running speed of the passing train. The pressure of crossing side and uncrossing side for the container flat wagon is almost equal since the one-dimensional characteristic of pressure distributing induced in the tunnel is not faintish. Consequently, the value of the lateral force and overturning moment of the container train generated in open air is greater than that generated in the tunnel, about 1.1 times.

研究结果表明：集装箱平车以160 km/h的速度与动车组等速交会时，在隧道内会车时车载集装箱中部压力变化幅值是在明线会车时的3.46倍；在明线和隧道内会车时，集装箱列车受到的侧向力和侧滚力矩均与交会列车运行速度近似成平方关系；因隧道内压力分布一维特性较强，集装箱平车交会侧与非交会侧压力相差并不大，因此，在明线会车时集装箱平车受到的侧向力和侧滚力矩均比隧道会车时的大，大约是其1.1倍。

The university library strategic plan evaluation designed by this paper is divided into 2 first grade indexes, 9 second grade indexes, and 33 third grade indexes. The two scales are the plan's design and content. The second grade indexes are clarity, attractability, democracy overall, feasibility, etc. This scale is the third class, which contains 33 evaluation questions, such as logical structure, document layout, librarian participation, strategic emphasis and strategic target, etc.

Cultivated land quality was assessed by BP neural network in Dazu County, Chongqing. The assessment results showed that paddy lands were mainly of the second-grade and third-grade, while dry lands were mainly of the first-grade and second-grade. It illustrated the high natural quality of the cultivated land, but the natural quality only reflected land natural characteristics. Therefore, influence coefficient was used to modify natural quality index based on the investigation to households. At the same time, by using the household income as the value of cultivated land, the impact of natural quality and investment structure on the value were further discussed. The results showed that trinomial equation and binomial equation were fitted to reflect the relationship between natural quality and income.

该文采用BP神经网络模型对重庆市大足县耕地自然质量进行评价，发现研究区水田自然质量等级以二等地和三等地为主，旱地以一等地和二等地为主，耕地自然质量总体偏高；但耕地自然质量仅仅是耕地自然属性的反映，因此在基于对研究区农户行为调查的基础上，采用"影响力系数"对耕地自然质量进行修正，并将农户收益作为耕地质量货币化价值的表现，进一步讨论了耕地自然质量和农户投资结构对这种价值的影响以反映对耕地质量的影响。

Because of the eleven-plus the physical education in class was taken into physicaltraining in grade. Many courses were not taught to the students.
