A surface pattern detecting method includes: capturing a surface image of a sample element to be detected, wherein the surface image containing N grayscale pixels and wherein the N is a positive integer; selecting f×N pixels with small grayscale value based on a selection ratio f in order to define a pattern zone and further calculating a pattern mean of the pattern zone based on pixel amount and grayscale value of the pattern zone; selecting f×N pixels with big grayscale value in order to define a background zone and further calculating a background mean of the background zone based on pixel amount and grayscale value of the background zone; and determining whether the surface image has a defect based on the pattern means of the pattern zone and the background mean of the background zone.

A device for making distilled spirit includes a distiller body which has a storage container and a temperature sensor is connected to an outside of the distiller body and located corresponding to the storage container which includes a heater and a condenser connected thereto. The condenser is connected to an outside of the distiller body and has an automatic control switch. A lid is removably connected to the distiller body and a feeding device is connected to the lid. The lid has a control valve for controlling ratio of yeast and glycolytic enzymes. The temperature sensor, the automatic cooling switch, the control valve, the heater and the cooler are connected by the control panel.

The present invention provides a low alloying element-doped titanium and a casting cast therefrom. The doped titanium of the present invention includes titanium and from about 0.01 to 3 percent by weight of an alloying metal selected from the group consisting of bismuth, silver, hafnium, tantalum, molybdenum, tin, niobium, chromium and copper based on the weight of the titanium. The doped titanium of the present invention has improved castability and a decreased surface tension compared with pure titanium.
