The software of this system consists of the recording programme abbreviated BCJLfor importing the contrast surveyingF、Z) data acquired by two proton precession magnetometers into a PC-1500A-CAS in the field,the data transfer programme(named BCTX-1) which transfers the data from a PC-1500A-CAS to a PC, and the data receiving programme(named BCTX-2) with a PC to receive data from a PC-1500A-CAS.
Adopted radio automatic record method, the system includes 12 remote survey sites and stations, 1 central receive and control station, 2 transmit stations and 3 leading unit receiving systems.
2.Research all time transient electromagnetic response affected by primary induction voltage and its transient process, and analyze all time transient response changing with the receive coil electrical parameters, also demonstrate to gain all time secondary field by removing primary field and reduce earliest sampling time in order to achieve smaller exploration depth.
According to the circs of a bunch of rays set up from the source to the receive point, the try-shooting method gets the traveltime at the receive point by the interpolation between two traveltime of rays close to the receive point.
During DDL-Ⅲ cement bond logging tool is compatible with China-made SKH2000 computerized logging system, there are several problems, e.g., their different power supplies, different reception and transmission mode of CCL signal and how to process CCL signal.
Through utilizing hardware interfacing,debugging,database and network technologies, this paper developed a set of real-time hydrologic information processing software which have such functions as real-time reception, visual display, accurately storing information, warning when observed hydrologic values being over their limits, and sending hydrologic information to the offices of higher level via the network without the human intervention.
3. Aiming at the complicated earth's surface condition of front-zone of mountain, how to select the exciting method and the parameter, how to optimize the environment of exciting method and reception, how to pledge the normal combination of the datum of different exciting method;
In common circumstances, the omployment of seismograph with wide frequency band reception,proper record fourth and suitable traverse span as well as large dynamic range will help to obtain reflection wave of deep stoeply-dipping interface;
This paper deals with a secretary problem on fuzzy sets, which allows both the recall of applicants and the uncertainty of a current applicant receiving an offer of employment.
Without the need of any manual programming, the metal arc spraying and brush plating (if necessary) processes can be performed automatically and efficiently after receiving the 3D CAD data of the pattern.
With a digital sampling and processing system designed with VC++ in Windows platform, the real-time controlling procedure, high-speed receiving and sending data can be carried out, and the results can be displayed too.
Seven seeds receiving hits of HZE (high atomic number and high energy) particles from space were selected for further analyses and variable genomic polymorphisms were detected in all plants that developed from these seeds.
Compared with the dynamic threshold method, the balance encoding scheme can be implemented more easily, and is more robust to the channel time variant characteristics, the channel estimation of RAKE receiver and the combination techniques.
However, in this case, due to the rapid time-variability of the underwater channel, and the influence of inter-symbol interference (ISI) and inter-channel interference (ICI), the conventional rake receiver may fail to function.
One is a verifiable scheme which each participant can verify his own share from dealer's distribution and ensure each participant to receive valid share.
To receive habitus accurately and to obtain the reorganization and decision information of the object fully, spatial and temporal fusion must be taken into account.
It is shown that on fulfilling sufficiently soft conditions of the "valid competition," all local market agents can receive an appreciable increment of the profitability.
The fast exhumation (0.34 mm/a) at 23.7 Ma, which recorded the tectonic uplift of West Qinling, led to the formation of the Neogene Tianshui basin and initiated the reception of alluvial deposits.
Correlation reception and its matched filtering are shown to be particular limiting cases of the spectral-time filter, whose operation is explained in terms of the properties of the spectral correlation function.
Sciatic nerve damage led to a defective functioning of the renal mineralocorticoid receptors due to the disturbed neurotrophic supply of this organ: the reception of distorted nervous stimuli.
At the same time, the pharmacological stimulation of the sympathetic nervous system leads to an even more defective aldosterone reception by the kidney.
The physical characteristics of whistler ducts in Earth's magnetosphere is inquired theoretically. By using two kinds of model of ducts in which the VLF electromagnetic waves are guided, we obtain the distributions of magnetic field and current in the whistler duets. When the magnetic field deviates from potential or force-free field, the field-aligned current can be produced, and it relates closely with the intensity and lifetime of ducts. On the basis of these results, we may conclude that a stronger fiel...
In 1978, we designed and made SH-1 pquipment for receiving whistlers and VLF emissions. In order to study the spectrum characteristics of whistler intensity, the frequency response of the equipment including antenna is paid special attention, and the frequency response of the loop antenna is rectified. This equipment has been used in Beijing (Geomag. Lat. 28.9#N) since the summer of 1979, and some new results were obtained. They are: 1. the maximum of relative intensity of whistlers is situated between 1 kc...
Based on the data of whistlers and tweeks observed at San Ya (18.24° N, 109.5° E; magnetic latitude 7.04°N), Hainan, China, the physical features of low-latitude whistlers are studied. The results of observations and theoretical analysis show that the ducted whistlers propagating along the field-aligned ducts can be received at low latitudes. The results show indirectly that the ducts of whistlers also exist in the ionosphere. The critical cutoff latitude of ducted whistlers may be located at the region wit...
