In contrast,the disturbed power system trajectories recorded by data measuring instruments as Phasor Measurement Units(PMU) can reflect the real dynamics of power systems.

Take the NGFW4000UF firewall as the test object to form the basic Client/Server model,thus we designs the test system to carry on the implementation analysis the applieation process in satisfies the transmission data measuring error under the premise.

The design project of GPS attitude data measuring and acquisitioning system based on DGPS and GPS/INS is proposed. With the analysis of the difficulties and parts of the software, the development of this software was done with the interactive software development platform C++ Builder 6.0. The test shows that this system meets the engineering needs and is something useful.

Based on above, a kind of rheometer was develoed, by which data measuring and storing and rheological parameter calculating could be done automatically.

It is pointed out that the higher functions of harmonics can be further developed using this harmonic meter,such as harmonic data measuring,harmonic database establishment,harmonic power flow calculation,harmonic resonance analysis,harmonic simulation,etc.

According to the idea of modem industrial control theory, control function should be more distributed, and so the design idea of'the more distributed the control, the less the danger' will be arrived. In the filed bus control system, the control is performed basing on data measuring and the danger of control becomes more distributed. Therefore, it can meet the safety demands of control which modem industrial production needs.

The system proposed is just for the rope travel measurement purpose. The system adopts AT89C52 as the kernel, including the data measuring component, the data storing component, the clock chip component, the LCD display component, the data communication component, the system supervising component, and so on.

An analyzer has been designed for the analysis of ion density for cobalt. The instrument is based on flow-injection and Lambert-Beer theorem. The MCU 89C52 is the core of the instrument,so that the automatic control of functions,such as liquid stream driving,sample loading and injection,detection,data measuring,data processing and display were realized.

This paper examines the combined use of a prospective view of length of stay (LOS) using life table analysis and examinations of point-in-time data measuring the LOS of individuals hospitalized on a given day.

The approaches among these states to collecting on-site monitoring data (measuring compliance) and evaluating sites are variable.

Engng Sci.44, 2881-2897) is applied to literature data measuring chemotactic bacterial population distributions in response to steep as well as shallow attractant gradients.

We urge production of comparable country data measuring progress towards clear sustainable production and consumption targets.

We tested our model with annual data measuring the budget balance of the ten Canadian provinces.

The present study is a part of the studies to search for the concrete approaches of rice breeding for improvimg the efficiency of photosynthesis. In 1975-1977, net photosynthetic rate (Pn) of flag leaves of 329 varieties of rice were measured with infrared CO_2-analyzer at full heading stage. The followings were clarified:1. The range of varietal differences of Pn was wide. The ratio of the maximum value to the minimum one was about 2 or more. Pn of variety Pearl Dwarf which was extensively cultivated...

The present study is a part of the studies to search for the concrete approaches of rice breeding for improvimg the efficiency of photosynthesis. In 1975-1977, net photosynthetic rate (Pn) of flag leaves of 329 varieties of rice were measured with infrared CO_2-analyzer at full heading stage. The followings were clarified:1. The range of varietal differences of Pn was wide. The ratio of the maximum value to the minimum one was about 2 or more. Pn of variety Pearl Dwarf which was extensively cultivated in Kwang tung province was nearly equal to the average of all measured varieties.2. On the basis of calculation of data measured under the same conditions with 51 varieties, the variation coefficient of Pn of individuals within the same variety lies mainly in the range of 6-12% and that among varieties was 15.82%.3. By means of analysis of variance with experimental results obtained at three growth seasons in two years, it has been found that the difference of Pn among varieties of rice was significant at 1% level.4. By means of analysis of correlation with experimental results obtained at four growth seasons in two years, it was recognized that the ranking of Pn among varieties of rice was for the most part relatively stable.(writer: Tu Tseng-ping)

In this paper,we discuss the structure and stress analysis of the penstock wye with the internal crescent web reinforcement which has been studied and used as an important part of the hydrostation in our country since the year of 1974.As it is constructed of some cones and plates, which is a combined structure of plates and shells;there exists no any analytical method,as yet,to solve for its stresses.Thus,the finite element method is used and the results are obtained with the aid of the computer, which are compared,in...

This paper describes the time-domain electromagnetic response above the surface of a homogeneous earth for the application of the impulse type airborne electromagnetic method. The formulations of the response are developed from the those of the frequence-domain by the Fourier transform. Both the horizontal and the vertical component of the secondary field were computed with the parameters of the home-made impulse type airborne electromagnetic system.

This paper describes the time-domain electromagnetic response above the surface of a homogeneous earth for the application of the impulse type airborne electromagnetic method. The formulations of the response are developed from the those of the frequence-domain by the Fourier transform. Both the horizontal and the vertical component of the secondary field were computed with the parameters of the home-made impulse type airborne electromagnetic system. According to the computer results of the time-domain, the diagrames of interpretation are presented in this paper. It can be used to solve two major problems. The first is to interpret the time-domain airborne electromagnetic data measured at different flying altitude so that the earth resistivity will be provided. The second is to estimate the time-domain airborne E. M. response, if the earth resistivity is given; therefore the pseudo-anomalies caused by the change of the flying altitude will be corrected.
