Taking the characters of Road Transport Service in information-based war into consideration, analyzing the necessity of road transport service training simulating system, the paper puts forward total and particular plan. At last, the simulating system of training based on road transport service validates the possibility with a concrete training item.

We study the squeezing and the amplitude-squared squeezing of radiation field in the interaction of squeezed vacuum state with two two-level atoms, and discuss the effects of the relative value of two atom-field coupling constants on them. The numerical results show that the presence of one additional atom introduces nontrivival cooperative effects into the squeezing and the amplitude-squared squeezing of radiation field.

In multi-hop self-organizing tactical data link system, some real-time message streams need more than one slot to transmit in a frame, and have strict rate requirements and distance constraints. It is very difficult to guarantee Quality of Service (QoS) in thus system. To solve the problem , we propose a TDMA slot assignment protocol, named adaptive-frame-based dynamic slot assignment protocol (ADSAP), which can change the frame length dynamically by setting frame length as a power of 2 slots. ADSAP assigns one or multiple unassigned slots to a node according to its message stream model. If there is no unassigned slot available, the frame length can be enlarged to generate unassigned slots, and if there is too many unassigned slots in the frame of a node, ADSAP can shrink the frame to improve channel utilization. Furthermore, we verify the effectiveness of our proposed protocol by simulation experiments. The results show that our proposed protocol can meet the needs of the information delivering in tactical data link, and has better performance as compared with the conventional protocols.

The human skin is a complex organ in structure and function. There are at least four types of cell present in the epidermis. The skin keratinocytes are the major epidermal cells. This cell or a related stem cell has the capacity to form both the stratified epithelium of the epidermis and the epidermal appendages found largely in the dermis.

Emission spectra of two atoms coupled by dipoie-dipole force in two-mode cavity fields are studied. It is found that emission spectra manifest the following new properties when two-mode cavity fields are initially in various-number states. When two fields are all in vacuum states, the spectrum shows six peaks and five peaks alternately, with the increase of δ＝ｇ a ／ｇ. Furthermore, the non-symmetric five peaks appear in the spectrum when δ is very small, which reflects the atomic dipole-dipole interaction more sensitively compared with the spectrum of two atoms in a single-cavity. The spectrum consists of symmetric six peaks and distance between each two symmetric peaks is proportional to (2ｎ 2 ) １／２ ｇ when one of the fields is in the vacuum states and the other is a strong field. However when one of the fields is in the vacuum state and the other in number state and δ＝2 １／２ ，the spectrum will generally show non-symmetric six peaks structure, but when ｎ 2 ＝５, it becomes non-symmetric five peaks structure.

In this paper, we show that: when the wave vector Q is not infinitesimal but sufficiently small, there exist mobility edges in the region of V < 2 in the Aubry model of one-dimensional incommensurate systems. On the condition of Q tending to zero the mobility edges are Ec=±|2-V|, The result is different from that of duality theory.
