The new BMW 3 Series has very well-equipped chassis protection, and the use of large-area protective plates prevents the oil pipeline from being directly exposed to the bottom of the vehicle.

If the production is arranged from the front process to the back process according to the traditional processing sequence, the higher the production efficiency of the process, if its rhythm is not suitable for the back process, the more waste of manufacturing surplus will be generated. Therefore, JIT production reverses the traditional way of transferring parts from front to back, and puts forward the order requirements from the back process to the front process according to the order method. The front process only provides the necessary products in the necessary quantity when necessary. Users can supply as much as they need, thus realizing "zero inventory" and not occupying working capital. Commodities that users do not need will not be produced, which can avoid overstock, obsolescence and deterioration of commodities, and can also avoid the costs of loading and unloading, handling and inventory.　　自从《蓝色星球》2001年开播以来，我们对大海之下生命的理解被彻底颠覆了。从北极熊出没的北冰洋到焕发着勃勃生机的蓝色珊瑚环礁，本系列纪录片同大家分享一些令人吃惊的新发现；邂逅在南冰洋深处神出鬼没的奇怪章鱼，观赏巨大的鲹鱼跳出水面，飞跃到半空中捕鱼；骑在虎鲸的背上，同它一起冲向鱼群。《蓝色星球2》带领我们体验让人敬畏称奇的新地方，见识魅力四射的新物种，了解非同寻常的新行为。
