There is provided a surface treated product that moves relatively in a fluid, wherein a surface of the surface treated product has continuous dimples, each dimple having a diameter of 10 to 2500 \u03bcm and a depth of 50 \u03bcm or less. The swing contains an elevated support having two hooks spaced apart perpendicularly to the direction of motion of the swing. The infrared radiation from the test layer has a period having a length which is indicative of growth rate of the layer. Each macrostate represents a state that the computing system is able to enter as a whole. The second layer of solder balls electrically and mechanically connects the interposer to the board.
