Partly because it takes a very long time to get there, logistically it's quite a challenge. Because you have to spend time acclimatising to the altitude.

这部分是因为要去那里得花上很长时间，原则上说，是极富挑战性的，因为你要花那么多时间才能到达那么高的山。

The technology of electric information is developing very fast and make much more and more electric products teem,which develop in the direction of handy and miniaturization,such as mordern times communication equipmen、handy electric product、luggable computer、electric car、moonlet,and so on.it is used at large that the power supply make use of storage battery.hower most of storage battery can but use appropriative chargers,that need long time in the electrification and can't judge the electrification parameter and spare electrification time.thus it need a have much function and handy intelligent charger device that is a far-ranging application different kinds and types.the text integrate upwards request that will introduce a device and system of intelligent charger base on singlechip.in the power supply loop,the transformer take the voltage from 220v to 12v,then the rectifier circuit take the voltage turn to 14v,it is by way of the voltage of electrification power supply.

内容提要：电子信息技术的快速发展使得各种各样的电子产品不断涌现，并朝着便携和小型轻量化的趋势发展，现代通讯设备、便携式电子产品、笔记本电脑、电动汽车、小卫星等普遍使用蓄电池作为电源，应用非常广泛。然而大多数设备中的蓄电池，只能使用专用的充电器，而且普通的充电器大多充电时间长，无法判断其充电参数和剩余的充电时间，那么就需要一种广泛应用于不同种类和型号的可知道其充电参数和剩余充电时间的多功能便携式通用智能充电设备。本文结合以上要求介绍一种基于单片机的通用智能充电器的设计。

Aimed at some shortages in the existing methods based on piecewise polynomial representation, such as sensitive to noise awl lower computational efficiency, a robust method of optimal segmenting time series is proposed.

针对分段多项式回归方法存在计算效率低和对噪声较敏感等缺点，提出了具有稳健性的最优分割方法，以解决时间序列数据相似搜索及知识发现处理中的长时间序列分割问题。

Over a span of 20 years, the researchers studied a group of 241 healthy elderly volunteers, giving them regular tests designed to measure their thinking or cognitive powers.

在长达20年时间里，研究人员们对241位老年志愿者进行研究，一定时间的对他们进行测试然后对他们的思维和认知力进行检测

However, the pain is very short, because it is subject to the protection of the skin is not easy to be stimulated for a long time.

不过，痛的时间很短，因为它受到皮肤的保护，不容易长时间地受到刺激。
