Three Mb class three-cylinder 4-8-0 locomotives were built by NOHAB for HNJ in 1931, based on an older type, the 2-8-0 M class built in Germany in 1922. [1] [2] HNJ changed their type designations the year after, and the Mb class became the G12 class, where G meant that they were intended for freight trains (Swedish: godståg). …

The Mb, later G12 class of Halmstad – Nässjö Järnväg (HNJ), known after nationalization in 1945 as the E9 class of the Swedish State Railways (SJ), was a type of steam locomotive built primarily for freight traffic. They were the basis for the nearly identical SJ E10 class.

För att hantera den ökande godstrafiken på HNJ utvecklade Nohab en kraftfull godstågsmaskin som ändå hade ett förhållandevis lågt axeltryck. Loken gavs inledningsvis littera Mb. Tre lok levererades 1931 och ytterligare tre 1936, under tiden hade litterat ändrats till G12 1932. Loken var trecylindriga och hade överhettare, Walschaerts ...

MB：兆字节，就是一种存储单位，1MB=1024KB。 KB：计算机中表储存容量大小的单位，用中文表示就是“千字节” 。 大小对比：从大到小顺序为MB（兆Zhao）、KB。 扩展资料. 基本数据单位换： 1B（Byte字节）=8bit. 1KB (Kilobyte 千字节)=1024B， 1MB (Mega byte 兆字节 简称“兆 ...

GB、MB、KB分别是：GB：吉字节（GB、Gigabyte，在中国又被称为吉咖字节或京字节或十亿字节或戟），常简写为G，是一种十进制的信息计量单位。 MB：兆字节（Megabytes）是计

毫巴 （简写mbar或mb）即1/1000巴, 这是一个用于测量压力的物理单位。1毫巴等于1帕 （hPa）。用单位面积上所受水银柱压力大小来表示气压高低的单位。 物理学上，压强的单位是用"巴"表示的:每一平方厘米面积上受到一达因的力，称为一巴。

注意s小写，是floating point operations的缩写（s表复数），意指浮点运算数，理解为计算量。 可以用来衡量算法/模型的复杂度。 Image大小为 5x5，卷积核大小为 3x3，那么一次3x3的卷积（求右图矩阵一个元素的值）所需运算量： (3x3)个乘法+ (3x3-1)个加法 = 17，要得到右图convolved feature （3x3的大小）：17x9 = 153. FLOPs = [ (C_ {in}*K_w*K_h)+ (C_ {in}*K_w*K_h-1)+1]*C_ {out}*H_ {feature\_map}*W_ {feature\_map}
