The second, the flame shape and color were determined by the concentration gradient of the place near the igniting position.

其次，火焰的形状和火焰的颜色是由点火位置附近的浓度梯度决定的。

These factors include magma composition, convection, diffusion, thermal gradient, oxygen fugacity, temperature, pressure, the shape of magma chamber etc.

影响韵律形成的因素很多，通常包括岩浆成分、对流作用、扩散作用、热梯度、氧逸度、温度和压力等。

For example, you can use a horizontal gradient to fill a shape with color that changes gradually as you move from the left edge of the shape to the right edge.

例如，您可以使用水平渐层，以随著您从形状左边缘移动到右边缘时逐渐变更的色彩来填满形状。
