  channel

Aliasing error bounds are derived for one- and two-channel sampling series analogous to the Whittaker-Kotel'nikov-Shannon series, and for the multi-band sampling series, and a "derivative" extension of it, due to Dodson, Beaty, et al.

Aliasing in the one-channel case is shown to arise from a transformation with similarities to a projection.

An Estimation of the Truncation Error for the Two-Channel Sampling Formulas

Guanidine-type compounds that reached clinical status include amongst others the potassium channel opener, pinacidil and the histamine H2-receptor antagonists (e.g.

The tetra-n-butylammonium cations were stacked to give two columns within each channel with cross-sectional size of about 2.30 nm × 0.93 nm.

  waterway

This important waterway is the subject of considerable international disagreement over whether Turkey possesses the lawful right to regulate vessels carrying goods and petroleum through the straits.

With the rapid development of China's foreign trade, the coastal and inland waterway transport has been increased rapidly.

Although a split and turbulent age, the Wei, Jin, and Northern and Southern dynasties, known as the Six dynasties, witnessed a continuous expansion of waterway communication and transportation between north and south China.

A significant waterway from Hangzhou to Tianjin held the greatest potential for development during this period, eventually leading to the construction of the Grand Canal in the Sui dynasty.

  watercourse

The calculated dependences for determining all the necessary parameters of the seepage flows and constructing the curvilinear watercourse profiles are given.

In the case of a circular basis for the shape of the watercourse profile in the plane of the Joukowski variable these dependences coincide with the well-known exact dependences.

The possible steps for reducing the pollution of water in a watercourse are discussed.

Modification of Pantle-Buck Technique for Assessing Watercourse Pollution Based on Macrobenthos Quality Characteristics

Data collected at 245 watercourses in the central European Russia are used to study the correlation of the new index with the anthropogenic load onto watercourses, as well as with the watercourse type and size and the type of substrate.

A mathematical model for the automatic control system of the unit of the hydropower station with a long complex conduit system is developed in this paper, and analysis of stability and dynamic characteristic for the turbine control system is made with the eigenvalue method of the coefficient matrix A of state equations. This method is also appropriate for general hydrorower stations.

The coast near Jianggang is located in Dongtai County, Jiangsu Province. Its offshore is just in the center of the well-known North Jiangsu Submarine Sand Ridge Field where two tidal wave systems converge. This paper chiefly discusses the influence of submarine ridges on the development of Jianggang coastal zone. In 1974, a great proxigean spring tide caused extremely high water in the coastal zone.

The coast near Jianggang is located in Dongtai County, Jiangsu Province. Its offshore is just in the center of the well-known North Jiangsu Submarine Sand Ridge Field where two tidal wave systems converge. This paper chiefly discusses the influence of submarine ridges on the development of Jianggang coastal zone. In 1974, a great proxigean spring tide caused extremely high water in the coastal zone. The enhanced tidal action cut Jiangjiasha, a large submarine ridge, into two parts, and some main tidal channels were realigned. Subsequently, a series of events took place one after another. For example, the high water level in second-order channels was raized; tidal flat around Jianggang area was seriously eroded; some new channels were formed on tidal flat of offshore banks; some ridges merged and others cut apart, and etc. These facts show that an abnormal change of tidal action, such as the extreme high water under optimum astronomical tide-producing condition and/or large storm, can cause notable changes of the main pattern of tidal channels, at least, in some localities. These changes lead to both increase and decrease of tidal strength in the channels. Consequently, the neighbouring flats must also be adjusted morphologically ot fit the above changes. This adjustment carries out in a large area and over a long period of time Events like the above are important not only in determining the dynamics of the coast, but also in the evolution of the submarine sand ridge field.

江苏海岸的一大特点是岸外内陆架上有一大片水下沙脊群。由于东海前进潮波系统和废黄河口外旋转潮波系统的西翼在弶港岸外相遇,故使东台县沿海一带成为这片沙脊的辐射中心区。 1974年以来,弶港地区海岸动态发生强烈变化。通过现场和卫片分析发现,1974年新发育成的大型潮汐水道把蒋家沙隔为两半,与上述变化有因果关系。而1974年特大天文大潮是造成蒋家沙被分为两半的主要因素。这次突变事件在条子泥西侧所带来的后果如下:1)王家槽西段潮位增高,涌潮加强;2)王家槽向西发展曲流超过了过去的最西界;3)王家槽东段淤浅,使条子泥和蒋家沙在该处并滩;4)条子泥南坡形成了新的潮汐支道;5)死生港大辐度西摆,严重冲刷西侧岸滩;6)川港淤积加速。

Until now, the traditional method of bottom and slope protection is still being used to treat the declination of navigation canal, but it is not effective in the prevention of the destruction due to the hydrodynamic force generated by steamboat movement. Based on the data of the hydrodynamic phenomena, sediment movement and historical investigation obtained along the Nantong-Yangzhou Canal, the process of development and evolution of navigation canal has been studied.

Until now, the traditional method of bottom and slope protection is still being used to treat the declination of navigation canal, but it is not effective in the prevention of the destruction due to the hydrodynamic force generated by steamboat movement. Based on the data of the hydrodynamic phenomena, sediment movement and historical investigation obtained along the Nantong-Yangzhou Canal, the process of development and evolution of navigation canal has been studied. Some efforts have been tried to establish the pattern of evolution of navigation canal network with locks and weirs on plain due to the hydrodynamic force generated by steamboat movement and the way of regulation of navigation canal of this kind.

现代船舶水动力不断侵蚀通航运河水道边界,引起运河航道的日益恶化萎缩,水运界虽然普遍采取了传统的护底与护岸的方法作为对策,但至今国际上尚未能够防治这类水动力的破坏作用。本文在江苏通扬运河航道实测船舶水动力、泥沙运动以及历次航道普查等资料的基础上,研究这类运河航道在自然界中的发育过程,并试图建立在现代船舶水动力条件下平原水网区闸化后通航运河的一套演变模式,从而探索因势利导的整治途径。
