In the early morning of the 10th, China successfully launch the Tianzhou-4 cargo spacecraft into space with the Long March 7 carrier rocket, and the construction phase of the Chinese space station began.

At 1:56 a.m. on May 10, the Long March 7 carrier rocket lifted the Tianzhou-4 cargo spaceship into the air. About 10 minutes later, the spaceship and the rocket were successfully separated and entered the predetermined orbit. At 2:23, the spacecraft solar energy The windsurfing board started work smoothly and the launch was a complete success.

This is the first launch in the construction phase of China's space station and the fourth expedition of the space station's cargo transportation system.

The summer night is deep, and the coconut wind is blowing. Inside the Wenchang Space Launch Site, the Tianzhou-4 cargo spacecraft and the Long March-7 carrier rocket are ready for launch.

"Tianzhou-4 is China's first spacecraft to enter the construction phase of the space station. It has loaded more than 200 pieces (sets) of cargo, with a total weight of about 6,000 kilograms. It is responsible for providing material support for the Shenzhou 14 astronauts and the space station. tasks such as orbital operation support and space science experiments," said Dang Rong, deputy chief designer of the cargo spacecraft system of the Fifth Academy of Aerospace Science and Technology Group.

"Attention everyone, prepare in 30 minutes!" At 1:26, the commander of Launch Mission 01, Wang Yuliang, resounded through the launch site.

Wenchang Space Launch Site is the only coastal launch site in China and is affiliated to the Xichang Satellite Launch Center. Since 2017, the Tianzhou series of cargo spaceships have successively flown from here to space.

"5, 4, 3, 2, 1! Ignite!" At 1:56, accompanied by a loud rumbling, the Long March 7 carrier rocket lifted the Tianzhou 4 cargo spacecraft into the air, drawing a gorgeous line in the night sky traces of.

The Long March 7 is China's new generation of medium-size launch vehicles. This is the first time that the Long March 7 has completed the test and launch within one month.

At 1:56 a.m. on May 10, the Long March 7 carrier rocket lifted the Tianzhou-4 cargo spaceship into the air. About 10 minutes later, the spaceship and the rocket were successfully separated and entered the predetermined orbit. At 2:23, the spacecraft solar energy The windsurfing board started work smoothly and the launch was a complete success. This is the first launch in the construction phase of China's space station and the fourth expedition of the space station's cargo transportation system.

"This time, the test and launch cycle of the rocket is 4 days shorter than that of the Tianzhou-3 mission," said Shen Dan, deputy director of the Long March 7 Launch Vehicle Model Office of the Aerospace Science and Technology Group.
About 10 minutes later, the spacecraft and the rocket successfully separated and entered the predetermined orbit. At 2:23, the solar panels of the spacecraft started to work smoothly, and the launch was a complete success.

So far, the curtain of the construction phase of China's space station has officially opened, and the key battle to achieve the "three-step" strategic goal of China's manned space project has begun.

At this moment, the combination of Tianhe core module and Tianzhou-3 of the space station is flying at a height of 400 kilometers in space, waiting for new members to join.

OPP七大原则:

◆开闭原则:对扩展开放,对修改关闭
◆里氏替换原则:继承必须确保超类所拥有的性质在子类中仍然成立
◆依赖倒置原则:要面向接口编程,不要面向实现编程。
◆单一职责原则:控制类的粒度大小、将对象解耦、提高其内聚性。
◆接口隔离原则:要为各个类建立它们需要的专用接口
◆迪米特法则:只与你的直接朋友交谈,不跟“陌生人”说话。
◆合成复用原则:尽量先使用组合或者聚合等关联关系来实现,其次才考虑使用继承关系来实现。

里氏替换原则:

里氏替换原则通俗来讲就是:子类可以扩展父类的功能,但不能改变父类原有的功能。也就是说:子类继承父类时,除添加新的方法完成新增功能外,尽量不要重写父类的方法。
按照里氏替换原则的要求,子类应该保留父类的功能,任何使用父类实例的地方都应该能用子类实例替换,以上的继承机制显然没有不满足该要求,所以从里氏替换原则的角度“正方形不是长方形”。

迪米特法则

又叫做最少知道原则,就是说一个对象应当对其它对象有尽可能少的了解,不要和陌生人说话。
强调只和朋友说话,不和陌生人说话。这里的朋友指的是:出现在成员变量,方法输入,输出参数中的类称为成员朋友类,而出现在方法体内部的类不属于朋友类。
迪米特法则初衷在于降低类之间的耦合。由于每个类尽量减少对其它类的依赖,因此。很容易使得系统的功能模块独立,相互之间不存在(或很少有)依赖关系。

CHECK TABLE tableName;
执行这个,如果表正常是下面的,如果不正常则会报表有错误,需要修复下
check table info

修复方式:

1.到数据目录下执行
myisamchk -r -c table_name.MYI

recovering (with keycache) MyISAM-table 'table_name.MYI'
