The major findings of this paper is the complex of the rat brain cortex in the local super-deep hypothermic effect duration is not more than 5 min, thermostat complex temperature brain blood flow recovered to baseline levels; on the ultra-deep hypothermia continuing role for more than 7 min, heated temperature and cerebral blood flow only recovered to about 75% of baseline values. These results suggest that the ultra-deep hypothermia short duration, low temperature effects on cerebral blood flow regulation function is reversible, and a long period of deep hypothermic effect may cause irreversible damage to the cerebrovascular regulation. The experimental results have laid a good foundation for further study of the ultra-deep hypothermic brain protection mechanisms for the establishment of the ultra-deep hypothermic cerebral protection time window. Laser speckle imaging technique as a non-contact technology. The log of  High Power Laser is referred by the relevant working personnel.
With high temporal and spatial resolution, provides a powerful means for monitoring deep hypothermia duration on cerebral blood flow changes in characteristics. Laser speckle for inspection and correction of non-normal eye. By research by the Department of Physics, Anhui University, Ye Liu, stone municipal joint study has been completed. The statistical properties of laser speckle plane movement at constant speed through the derivation of ground glass in the imaging system is proposed laser speckle movement and the corresponding relationship between myopia and hyperopia, and gives the laser speckle pattern in the vision correction applications. A bunch of collimated laser through the frosted glass in the subsequent surface phase is random, according to Huygens' principle, on the rear surface of the ground glass can be seen as a sub-wave source. The reference of laser pointers is kept in the workshop.
Each sub-wave source at any point in space superimposed on each other, will have a phase length or destructive interference. As the child the Boyuan the phase is random, so the intensity in the space position is also random. Results on the formation of the granular structure of the random distribution of the spot, called speckle. If frosted glass movement in its plane, observation plane speckle along with the movement, this speckle pattern is known as dynamic speckle, dynamic speckle movement mode. Through the derivation of a parallel beam in the imaging system in space - time cross-correlation function obtained observation plane speckle velocity formula, and then come to the characteristics of non-normal eye for myopia, hyperopia, speckle movement proposed correction of non-normal eye. It is to do the related research of laser pointers. Zumba Fitness DVD
The human eye refractive error checking and correction of the human eye is a good imaging system, the crystal is equivalent to the imaging lens, the retina is equivalent to the receiver plane. For the coincidence of the normal eye, the focal plane and the retina of the human eye, L2 = F → V-s = 0. Normal eyes observe speckle stationary state (strictly speaking, for the boiling of pure state "). Because myopia unable to adjust the focal plane on the retina, but in the retina before the L2> F, so the observed speckle pattern in the movement. Its direction of motion with the frosted glass of the direction of movement. The greater the myopia, the greater the distance between the focal plane and the retina, the greater the speed of speckle movement. We can wear a certain lens, makes the observation of speckles in a quiescent state. It is the development of technology of laser pointers.

The study found that brain temperature decreased more low, the less nerve cell energy metabolism and oxygen consumption, the better the brain cells, the protective effect can be effectively blocked serious cerebral ischemic diseases the pathological damage of brain cells process [3]. Brain tissue temperature quickly dropped to the ultra-deep hypothermia (≤ 16 ° C) level, while body temperature remained at normal body temperature, not only to achieve good brain protective effect and to avoid systemic deep hypothermia treatment in the complex heart and lung damage caused by temperature process [3]. But the ultra-deep hypothermic brain protection mechanism is unclear, and need to clear deep hypothermia cerebral protection time window. The clinic is necessary to ensure the normal biological tissues from the damage of ultra-deep hypothermia. The log of laser pointers gathers much information.
