A test method for testing the thermal mechanical fatigue performance of a test material includes preparing a test specimen of the test material, wherein the test specimen has a base, and a rib extending outwardly from the base. The treatment course, including eye exposure with magnetic field, transscleral low-energy laser radiation with wavelength of 1. The non-ionic hydrophilic polymer is preferably attached covalently directly to the part surface or to a polymer skeleton that is attached to the surface. The service processors can also perform the task of scanning for remote write pending bits to invoke the remote copy task, and checking for invalid track bits to invoke a task for copying data from a known good storage device to the device with the invalid track bit set. If one of the colors is lost, the printed colors change, the letters \u201cNG\u201d become discernable, and color loss can be easily determined. The atmospheric air introducing valve is brought into a valve closed state at times when a negative pressure is generated by the ejector under a condition in which a workpiece is held by the negative pressure generated by the ejector, whereby communication between the vacuum port and the atmosphere is blocked.
