There are some problems in the model of negative material circulation operation of electronic products,and the reasons are the technical problems in electronic reclamation and externality of negative material circulation operation of electronic products.
Taking a FORTH self-generator META88 developed by us recently as instance, after discussing the characteristics, current situation and optimal generating method of FORTH, this paper will describe all kinds of technical problems in the specific realization and put forward a technics of construction of self-generator.
The paper introduces the structure of water spray fire extinguishing system,application scope and the requirements for design and explores the technical problem when the water spray fire extinguishing system replaces the CF2ClBr fire extinguishing system.
Analyzed the current status of the biological pharmacy via plenty of the market survey and from the perspective of both theory and practices, and presented on the basic situations of Jishi Company and Shengmingyuan product, analyzed and studied the significant number of the concrete and technical issues confronted in the marketing operation of Shengmingyuan product by the basic theory of the marketing and the up to date marketing philosophy.
The purchase of equipment is an important job in construction of power plants. Through practice the author has understood the key technical issues related to the purchase of equipment as follows: influence of purchase package division, composition of purchase technical specifications, delivery term, subcontract, application of KKS codes and design revision on the purchase.
In view of this, this paper attempts to focus on some technical issues in concrete piano-playing practice, i.e. practice methods, fingering, phrase treatment, part practice and the resolution of some difficult points, etc.
Taking the the system for the study of computer languages as its original source ,the paper analyzed the past and the status in software of CAI and the general law of R&D of CAI software,solved some technological problems about CAI system,especially with respect to the system for the study of computer languages such as the judgement strategy of the testing problems ,the solving scheme for the security of CAI and the application of intelligent Agent in CAI as an emphases
Based on the results of the research in the mechanism of the charge and discharge of the lead battery, combining with accumulated managerial experience in practical work on board, the paper presents an account of the principle and the basis feature of the charge and discharge of the battery, from the application management point of view, and puts forward some technological problems related to daily management to provide reference for the managerial staff concerned.
The “stream medium” and “stream_medium” technology are introduced from three asp ects. The network's current development and the characteristics of education ar e combined to analyzed the technological problems solved by “stream_medium” f or audio and video message transmitting in network teaching. The new chance brought by the “stream_medium” for the network teaching is pres ented.
The problem considered arises in solving various technical problems associated with flows of a viscous fluid in a closed space near rotating plane surfaces, turbomachine disks, thrust bearings, rotational viscosimeters, etc.
In solving several technical problems it is necessary to know what takes place in a closed rotating axisymmetric cavity filled with a nonuniformly heated viscous fluid.
The measured energy spectra were found to be similar to those of neutron fields inside the cores of the nuclear reactors used to solve important scientific and technical problems.
In addition, some methods employed in the field as well as some technical problems are discussed in the paper, together with the means of obviating them.
Key technical problems of extra-high concrete faced rock-fill dam
For creation of an underground coal mine production system computer simulation model suitable for the situation of coal mines in China, some technicality problems such as: the method of track division, tramming control and travelling time calculation were discussed in this paper.
With the wide application of finite-element method to seismic exploration,some technical problems need to be solved urgently.A method for automatically forming the new finite-element grid is put for- ward;both the element information expressed by grid point and the grid point information indicated with element are shown in the paper. The advantage is that two adjustable means can effectively control the number of finite elements and may be compatible with triangular ele- ments and quadrilateral elements. Two...
With the wide application of finite-element method to seismic exploration,some technical problems need to be solved urgently.A method for automatically forming the new finite-element grid is put for- ward;both the element information expressed by grid point and the grid point information indicated with element are shown in the paper. The advantage is that two adjustable means can effectively control the number of finite elements and may be compatible with triangular ele- ments and quadrilateral elements. Two examples of automaticaUy forming the new finite-element grid for two models are given in the paper.This method proved feasible.
