Taking n-heptane as the raw matrials, under the conditions of the constant reacting temperature and the liquid space velocity of 10h-1, the regularity of selecting activity of CRC-3 catalsts changing with steam treating times was observed by using micro-reactor equipment.

On the basis of the simplified models for excitation radiatfon,it is stud-ied that the selective excitation produced by controlling the electron energy can be used to realize vari-able color luminescence under the condition of suitable variable color luminescence media.

A new multiplexing technique for polymer optical fiber is proposed,which is based on the principle that selective excitation can effectively decrease the modal dispersion and increase the bandwidth.

Variable color luminescence in ionized gases can be obtained by controlling the electron energy to produce selective excitation in a suitable variable color luminescence medium.

AIM: To evaluate the clinical efficacy on reduction of IOP using a Q-Switched 532nm neodymium (Nd): YAG laser, also known as "selective laser trabeculoplasty" to lower intraocular pressure (IOP) on patients with open-angle glaucoma (OAG).

And by use of these systems, the three selective stimulation methods using biphasic pulses proposed before(monopolar,bipolar and tripolar method)were studied on the models of mammalian myelinated nerve fibers.

The power of associative punishment doesn\' t come from the state power but the social power,so the associate punishment is lack of the support of state violence,and the generative logic is the selective incentives of collective action theory.
