嫦娥四号英语介绍

嫦娥四号到达月球背面大约花了27天，成为首个在月球背面着陆的人类探测器。

嫦娥四号着陆后将记录月球背面的环境信息。

他还会进行生物实验，例如在密闭容器中种植蔬菜和鲜花。

It took about 27 days for Chang'e-4 to reach the back of the moon, becoming the first human probe to land on the back of the moon. Chang'e-4 will record environmental information on the back of the moon after landing. He also conducts biological experiments, such as growing vegetables and flowers in closed containers. 嫦娥四号着陆的地形就比较崎岖，撞击坑大而且分布密集，对嫦娥四号着陆区的选择和着陆精度提出了很高的要求。

The landing terrain of Chang'e 4 is rather rugged, and the impact craters are large and densely distributed, which puts forward high requirements for the selection of landing area and landing accuracy of Chang'e 4.
一个月夜相当于地球上14天。

同时，月夜最低温度可达到零下180度。

在没有光照的漫长黑夜里，对于依靠太阳能提供能量的嫦娥四号着陆器来说，如何依靠自身存储的能量安全度过月夜将是一个很大的挑战。

面对这一难题，研制人员提出了休眠唤醒的概念。

A month's night is equivalent to 14 days on Earth. Meanwhile, the lowest temperature at night can reach minus 180 degrees. In the long dark night without light, it will be a great challenge for Chang'e IV lander to survive the moonlight safely by relying on the energy stored by itself. Faced with this problem, researchers put forward the concept of sleep awakening.
此外，巡视器还要面对月球表面昼夜温差变化大、低重力环境以及细小微尘的污染等问题。

据悉，在整个任务过程中，设计团队为巡视器定义了感知、移动、探测、充电、安全、休眠多种工作模式，以应对不同工作环境、适应不同工作状态的要求
In addition, the inspector has to face such problems as the large diurnal temperature difference on the lunar surface, the low gravity environment and the pollution of fine dust. It is reported that during the whole task, the design team defined a variety of working modes for the patrol, such as perception, movement, detection, charging, safety and dormancy, in order to meet the requirements of different working environments and different working conditions.。
