The deep water deposition means the deposition in the area where the water depth is larger than 30 meters, in which the major sediments are coarse sand and gravel. This kind of deposition is the relic deposition formed by the Pleistocene alluvial-lacustine deposition reworked under modern channel currents actions, and ususally the Holocene acummulation lack in the deep waters. The transitional zone deposition is the deposition between the low tidal level line and the 30 meters isobath, where the sediment types is changeable and the grain sizes are gradually coarsening from the low tidal line to the deep water area. This kind of deposition is developed by the deep water eroded sediments sorting under the transitional zone current action. The different types distributed along the isobath. The tidal flat deposition is the fine sediment deposition on the tidal flat which is flo sedimentation of the silty clay under the tidal flat dynamic action and ususally developed fluid mud on the lower tidal flat. The channel mouth deposition is the deposition in the channel mouth area. According to the sediment types, it includes sand deposition where there are coarse sediments supply and silt deposition where there are only fine sediments surpport.

Based on the aberration theory of AWG, a new-type flat-field AWG is designed. The focal signals of all wavelengths of operation are focusing along a straight line perpendicular to the propagation direction. Three stigmatic points restrain three dominant geometry parameters. Furthermore, a new-type flat-field wavelength router with both flat input field and flat focal field is also designed.

基于阵列波导光栅的像差理论，利用三个无像差点约束三个主要结构参量，设计了新型平场聚焦阵列波导光栅，使得所有工作波长的输出信号都聚焦在与光束传输方向垂直的直线上，并进一步将其拓展为同时具有平输入场和平聚焦场的新型平场波长路由器。

The main target stratum has the following characteristics: dominated by barrier-free clastic tidal facies, tidal facies are divided into three subfacies: supratidal zone, intertidal zone and subtidal zone. The tidal facies in Tazhong Area are mainly dominated by intertidal sand flat, sand-mud-mixed flat, intertidal mud flat and supratidal mud flat subfacies.

The chelate structure was examined by AFM scaning, single strand structure at AFM gram is Ala-Gln, two combined single strand is Ala-Gln-Zn~(2+), and atomic radius of Ala-Gln-Zn~(2+)'s conjunctive atom is about 0.24 to 0.25nm, which is near to Zn~(2+), so the conjunction atom is Zn~(2+). Thus the coordination reaction and the molar ratio 2:1 is proved again.

原子力显微扫描指出，大量出现的单一弯曲链状结构是Ala-Gln分子，而两两组合连接的链状结构，则是Ala-Gln-Zn~(2+)螯合物，且连接两个链状结构、半径约为0.25nm的中心原子是Zn~(2+)，证明Ala-Gln与Zn~(2+)形成配位比为2：1稳定螯合物。
