This period, the economic and cultural development in the six major areas: First, large-scale long-term Dynasty, greatly promoted the development of agriculture; Second is the backbone of the Jialing River waterway and road construction all over the conduct of a larger scale; Third, Emblem, bands such as the West and establish a state school official, and promote the prosperity of the education and culture; Four Tea-Horse Division is operated by the main tea plantation, Song, the national grasslands and tangutica highly active border trade; Fifth, City flood prevention-oriented care and the dam construction to start large-scale river training works; Sixth, the development and utilization of mineral resources from the project to the scale of all new development.

这一时期，经济文化的发展主要表现在六个方面：一是长期的大规模屯田，大大推动了农业发展；二是以嘉陵江为主干的水路和各地道路建设更大规模地进行着；三是徽、阶、西和等地正式建立起州学，促进了教育文化的繁荣；四是以茶马司经营的茶场为主，宋、金与甘青草原民族的边境贸易高度活跃；五是以防汛护城为主的堤坝修筑和河道治理工程大规模展开；六是矿产开发利用从项目到规模都有新的发展。

The underground root systems and the plenty of adventive roots growing on basis trucks can greatly reduce soil erosion by reservoir water. The 1 m×1.5 m allocation density of the Salix viminalis showed the best protection, and sediment yield was 8.64 kg/m^2, which decreased 74.38% compared to CK.

Large amount of geological material was studied with statistics and geomechanics method,and the distribution law of factures in Cuijiagou mine has been found out:the main fracture s are along NNE and SN directions,other small fractures are controlled by the main fracture s.

利用统计分析、相关因素、地质力学分析方法对崔家沟井生产中积累的大量实际地质资料进行分析研究，找出了崔家沟井田范围内断层发育展布的规律，即近SN向及NNE向断层是本区的主干断层，共它小断层为其派生产物，小断层的展布受主干断层的控制。

Results:(1) The two nerves were found anatomically related at 5～10 mm and 26～30 mm respectively following hypoglossal nerve entering the muscle.(2)The diameter of the two nerves were observed to match well with each other or with the main branches at 10 mm following the branching of hypoglossal nerve.(3) At 6～10 mm prior to the branching of hypoglossal nerve there was a branch going to the lingual muscles and plexiform of lingual nerve.

结果：(1)舌下神经与舌神经之间有二个恒定的联系部位，即舌下神经分支进入舌肌后最初5～10 mm处和26～30mm处；(2)舌下神经与舌神经最佳吻接部位，我们认为应在舌下神经主干分叉后10 mm左右；神经直径测量也发现神经直径与舌神经主干和分支直径较为匹配，且此区有利解剖，便于神经吻合；(3)舌下神经分叉之前，在神经干上方距分叉约6～10 mm处有一较固定分支，参与分布舌肌并与舌神经呈丛状结构。

This article through to the small leaf oak branch moisture contentdetermination and the analysis, take the small leaf oak's bough highlyas an independent variable, take the corresponding high branchmoisture content as the dependent variable,Uses the linear theory to construct the bough moisture contentestimation mathematical model, studies the small leaf oak boughmoisture content the distributed rule.

本文通过对小叶青冈主干含水率的测定和分析，以小叶青冈的树干高度为自变量，以相应高度的主干含水率为因变量，采用线性理论构建树干含水率估测数学模型，研究小叶青冈树干含水率的分布规律。

The measures of cultivation of disease-free seedling, reduction of wound of stem and twig, wound sterilization after peeling diseased patch of stem and twig, cutting down badly diseased twigs are effective control method.
