The flag was first used as an ensign for Russian merchant ships and only became official in 1696. The flag continued to be used by the Russian Provisional Government after the Tsar was toppled in the February Revolution and was not replaced until the October Revolution which established the Russian Socialist Federative Soviet Republic - the world's firstconstitutionally socialist state.
一开始旗子是俄罗斯货船的象征 然后1696年的时候被官方化了
毛子在二月革命推翻沙皇之后旗子继续被使用直到十月革命

The earliest mention of the flag occurs during the reign of Alexis I, in 1668, and is related to the construction of the first Russian naval ship, thefrigate Oryol.
关于这个旗子的起源最早的版本能追溯到1668年 毛子第一艘战船建造的时候

According to one source, the choice of the colours may originate from the flag of the Netherlands[5] and is related to the nationality of the ship's lead engineer Butler.
其中一个资料说明这旗子起源于荷兰 然后跟船的工程师巴特勒有关 后面我懒得复制了反正就是讲建造战船然后选旗子的故事
A different account traces the origin of the Russian flag to czar Peter the Great's visits to Arkhangelsk in 1693 and 1694. Peter was keenly interested in shipbuilding in the European style, different from the barges ordinarily used in Russia at the time. In 1693, Peter had ordered a Dutch-built frigate from Amsterdam. In 1694 when it arrived, the Dutch red-white-and-blue banner flew from its stern.[6] Peter decided to model Russia's naval flag after this banner by changing the sequence of colors.
另外一种说法就是关于彼得大帝1693 1694年去这个什么JB城市。。 彼得大帝对欧洲船只的构造很感兴趣 彼得大帝1693年订购了一搜荷兰产的护卫舰 然后1694年这破船到了 由于荷兰的国旗也是红白蓝三色 于是彼得大帝决定让毛子的海军旗也使用这三种颜色 只是改变了顺序

Many Russians associate white with nobility, blue with honesty, and red with courage or love.
这是大部分毛子认为的正确解释
白色=高贵（吾黄？）
蓝色=正直忠诚
红色=勇气或者爱

至于百度百科说的表示寒带亚寒带温带。。。 不知道是从哪看到的

水的好，我认输

巴黎不是有在俄罗斯的吗。让他抓几个俄罗斯人问问不就清楚了

其实央视的那个说法我一开始也觉得挺搞笑的，要是那样儿创造国旗有啥意思

一直以为颜色是 自由 博爱之类的含义

百度百科也不一定是对的
