I think the car stand out, make a U-turn and turn a problem.

我觉得这辆车进出站、转弯和掉头都成问题。

The thickness of the ice cover on the wall surface heat transfer is greater than the thickness of it on the air heat transfer form. The thickness of the ice cover on the wall surface heat transfer along the way changes slowly, but it on the air heat transfer along the way changes significantly. Reducing the entrance velocity, lowering the wall surface or air temperature, the formation of the thickness of the ice cover will increase; in the 3D circumstances, The thickness of the ice cover was relatively uniform in the import of the U-turn model, the ice cover was gradual accumulation in the convex bank when the stream traversed the import of the U-turn model, the thickness of the ice cover in the convex bank was significantly bigger than the thickness in the concave bank. The temperature field under the ice cover tends to be complex because of the existence of the secondary flows. The temperature in the convex bank is greater than it in the concave bank. Compared with the data from experiments, the laws in the numerical simulation are similar with them in the experiments

模拟结果显示：二维情况下，运用壁面传热形成的冰盖厚度大于运用空气传热形成的冰盖厚度，壁面传热形成的冰盖厚度沿程变化缓慢，而空气传热形成的冰盖厚度沿程变化明显，减小入口流速，降低壁面或空气温度等，形成冰盖的厚度都会增大；三维情况下，弯道入口处凸、凹岸形成的冰盖厚度基本相同，进入弯道后，凸岸形成的冰盖厚度逐渐增大，而凹岸的冰盖厚度逐渐减小，受横向环流的影响，冰盖下水流的温度场趋向复杂，并且凸岸的温度小于凹岸的温度；与实验室实验所得数据相比较，数值模拟研究得到的规律基本符合实验规律。

Human rights crisis may turn up in the unintegrated human-right society characterized by a vicious circle of infringement of human rights caused by that people cherish their own rights but turn a blind eye to others'.

人权社会是社会成员共同创建的，是大家从爱护本身的人权到热爱社会的人权而做起。

You could turn belly rings and unsoiled the entire length of it better than if you were to obtain barbells, but once your belly have already recovered, you could always turn to barbells.

你可以把肚子环和干净的了它的整个长度比，如果你是获得杠铃，但一旦你的肚子已经康复，你总是可以从杠铃。

I cut this down to two for Anaheim simply because I wanted to be able to cast my Birds of Paradise of Llanowar Elf turn one and follow it up with a turn two Viridian Shaman.

在Anaheim我只用了两张，因为我想确保在第一回合能放下罗堰或鸟，接第二回合的暗碧族祭师。

AEther Vial is particularly annoying if it comes down on the first turn, as it not only allows them to come out quickly, but also lets them sneak creatures past your countermagic or play Arcbound Ravager at the end of your turn to protect it from Viridian Shaman.

第一回合的以太瓶尤其恼人，它不仅能加快共鸣下兽的速度，还能废掉你的康牌，甚至可以在你回合结束放出吞吃兽，以躲过你的祭师。

It provides high resolution satellite images, aerial maps and detail street maps from Yahoo, Microsoft Virtual Earth, Ask.com and other sources, as well as local search, turn-by-turn directions and additional services.

它提供高解析度卫星图像，航空地图和详细的街道地图，从雅虎，微软虚拟地球， ask.com和其他来源，以及本地搜索，转弯路口方向和额外服务。

To be the leader of the saving cause. Although we do not contribute to the country too much, we can turn off the lights and the fans before leaving our classroom, we can reject the one-off chopsticks. Lunch boxes can be used to contain food instead of plastic bags. Use the notebooks which have been used a half and drink the rest water in the bottle . Turn off the running water tap and the working watering trough in time ...... wasting of energy is not far away from us, but saving is so close to all of us.

虽然我们暂时不能为国家贡献很多，但可以在离开教室时顺手关灯，关电扇，可以拒绝使用一次性筷子，可以用饭盒代替塑料袋来盛装食物，用完才用了一半的作业本，喝完瓶里的矿泉水；虽然我们暂时不具备开办节能企业的条件，但我们可以及时关掉还在滴水的龙头，可以及时关闭午休时还在工作的饮水器……能源的浪费离我们不远，节约也近在咫尺！

For me,it's well that Obama posed "change".There is an old saying that goes"eprivation leads to changes, changes in turn lead to finding a way out, and in turn becomes sustainable",that is,we should discard the old thinking model,and do our own thing well,and actively involved in responding to global issues, and to be responsible global citizens, and build a nice and harmonious "One World" in the future(by confucious,the utopia humanrace is longing for).

我认为奥巴马提出"变革"是对的，所谓"穷则变，变则通，通则久"，也就是要抛弃旧有的思维模式，做好本国的事情，积极参与应对全球问题，做负责任的全球公民，建设未来和谐美好的"大同世界"（孔子语，人类时代向往之理想国也）和"大容世界"。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
