通过在葡萄枝条出土、绑蔓期间设置不同的坐果高度，在葡萄转色期进行摘叶、架面下铺设反光膜等采前栽培技术，研究改变葡萄微气候的技术措施对酿酒葡萄品质的影响。结果表明，采用70cm的坐果高度、对结果部位进行摘叶、在架面下铺设反光膜的处理方式能够使酿酒葡萄的品质得到一定的提高。

Near my home is a small park, threre are many amusement sets free for children incluing swing, sliding board etc. the groud of amusement park is laid wood chips to avoid careless falling children be injuried. I hear about that will be rebuilt plastic ground. There is a tap water for visiter's drinking, the only inconvenience is no a toilet. It will be perfect if there had a washroom.

在我们住处右边附近有一个小公园，有为儿童设置的游乐器械，秋千、溜溜板等，都是免费，那些场地地面用木渣铺设，以免儿童不慎摔下来受伤，听说还要改造成塑胶铺设，这小公园还有为游人设置的自来水饮水装置，这个公园就是缺一个厕所，要是有一个厕所那就更好了。

After the contract signing in Beijing, design work commenced in Shanghai just 22 months before the launch. The keel laying took place in February 2006 when the frst of 282 massive steel blocks was placed in the dry dock.

在出坞前仅22个月，该船体建造合同在北京签署，随后设计工作便紧锣密鼓地在上海展开。2006年2月，282块船体钢铁组块中的首个组块在干船坞内铺设，船体组块铺设工程正式开始。

In order to solve the frost heave and thaw settlement, the model tests were made in Tibetan Plateau. Two kinds of model were designed to horizontal drain structure embankment and the ventilation embankment in suit. The effect of horizontal plastic drain was analyzed in contrast with the ventilation embankment. The mechanisms of horizontal plastic drain were studied in permafrost, such as gravity draining in the superficial layer and structure stiffing in the embankment in the theory. According to the design theory, the parameters of horizontal plastic drain were confirmed in the embankment. The values of deformation were inspected by fiber monitor system in the permafrost embankment.

为了解决青藏高原的冻土浅层雨季雨水下渗和蒸发所产生的冻土冻胀与融沉问题，在青藏高原开展水平排水板结构性路基和普通通风路基的原位模型对比试验，并从理论上探讨水平排水板在多年冻土路基中浅层重力排水和结构加劲的作用机理，确定水平排水板的铺设参数；运用光纤监测技术对水平排水板在多年冻土路基中的变形进行监测，对比分析水平排水板铺设与否这2种条件下冻土路基变形监测结果。
