  quantum size
     Compared with MoO_3 and TiO_2, the edge energy of MoO_3-TiO_2/SiO_2 was improved and a significant rise of the photon absorbing intensity is observed, which proves the coupled structure has stronger photon ability to take in the UV light, hold back the recombination of photoexcited electron-hole pairs and exhibit the quantum size effects.
     与本体MoO3和TiO2相比,复合后MoO3TiO2/SiO2的能隙值有所增加,在紫外光区的吸光强度也明显加强,使得光生载流子的复合效率得到抑制,并产生了一定的量子尺度效应.

Classical control theory and modern control theory have been applied to macroscopic systems.If the size d of controlled systems is small, that is, d has quantum size, then the existing control theory must be transformed into quantum form, i.e ,based on quantum mechanics.It is necessary to reform quantum control theory to satisfy the quantum principles. Some properties of quantum control theory are discussed on the basis of the control theory.

经典控制理论和现代控制理论只适用于宏观系统的控制问题描写 ,而当被控系统的尺度很小 ,以致于具有量子尺度时 ,现有的控制理论必需修改为量子论的形式 ,必需基于量子力学定律 ,重建一种量子论的控制理论 ,使之满足量子论原理 .在此基础上 ,文中进一步讨论了该理论的有关性质

Solid material of supported coupled semiconductors MoO_3-TiO_2/SiO_2 was prepared by the chemical modification method. BET, XRD, TEM,IR, Raman and UV-Vis DRS experiments were used to characterize the ~surface structure, photon absorbing and chemisorbing ability of the material. It was shown that there are some ~extremely small particles of anatase and MoO_3 crystallites dispersed well on the surface of SiO_2, which also can be coupled each other by the bonds of Ti-O-Mo. The active adsorption sites of the material exist on its surface, ~according to IR results, and C_3H_8 can be chemisorbed at the Lewis base sites of the Mo=O bonds to form molecular states. Compared with MoO_3 and TiO_2, the edge energy of MoO_3-TiO_2/SiO_2 was improved and a significant rise of the photon absorbing intensity is observed, which proves the coupled structure has stronger photon ability to take in the UV light, hold back the recombination of photoexcited electron-hole pairs and exhibit the quantum size effects.
