Some sub-models of the original KIVA code were modified, by introducing into the Kelvin-Helmholtz and Rayleigh-Taylor model for spray breakup, the multiple laminar and turbulent characteristic timescale combustion model, the heat transfer model of Han and Reitz, the Hiroyasu and Nagle soot model and the improved Shell auto-ignition model were added to the original KIVA, to improve the predictions of engine spray, ignition, combustion, gas/wall heat transfer and emissions.

为提高模拟精度对标准的KIVA程序进行了改进，引入KH-RT雾化模型、层流和湍流多重特征时间尺度燃烧模型、Han和Reitz传热模型以及Hiroyasu和Nagle碳烟排放模型来模拟柴油机多次脉冲喷雾、燃烧、壁面传热及排放过程，同时增添改进的Shell自燃模型来模拟着火过程。

However, in order to have your tyres retread they have to be kept in good condition as they can only be retread if the tread hasn't worn down too much.

然而，为了您的轮胎翻新它们必须保持良好状态，因为它们只能胎面翻新如果没有拖垮太多。

Attrition needs to waste more energy, but, if two faces can retroflexion, attrition force is met greatly decrease, and the energy that mobile place requires also decreased greatly.

摩擦需要消耗更多的能量，但是，如果两个面可以翻转，摩擦力就会大大的减少，而移动。。。。。。
