This article proceed from the basic situation of domestic construction industry and construction enterprise, analyses the favourable circumstances and challenge face the construction enterprise of China after entering WTO, and also present the appropriate measure to accomodate to the situation.

After the definition of appropriate measure is defined, two algorithms are given according to the measure, i.e., the least control nodemethod and the synthesized control method, are presented to quickly ascertain the amount of outage generators and theshedding of loads.

Firstly compares and analyzes the methods on 9 kinds of trees, under the condition of no appropriate measure tables or mathematics models, puts forward that the method of equal trunk of trees diameter class on model tree is the most accurate method;

It is shown that Parkin's pitch, plus an arbitrary constant, is the only appropriate measure of pitch.

In this paper, however, without any assumption for the expression of pitch we ask the question that whether there exist different appropriate measure of pitch other than Parkin's such that all the available finite screws also form a 4-system.

Comparison of the results with the commonly used Palmer Drought Severity Index indicates that the latter is an appropriate measure only when drought is widespread, and cannot be used to identify mesoscale droughts.

On choosing the appropriate measure of association when analyzing rating scale data

Theprocedure also incorporates the shortest rather than the mean squareddistance between a payoff vector and a set of predicted payoff vectorsas the appropriate measure of error.

This paper presents a method of determining the actual average temperature rise of the stator winding of a high-voltage a.c. machine, by measurig-the resistance of that winding under load by means of Kelvin bridge. The method discussed herein has the following special features:1) The installation for measurement is at zero potential, so that safety is assured in operation,2) By taking appropriate measures, disturbance of the a.c. components is Kept away from the bridge circuit, so that the installation...

This paper presents a method of determining the actual average temperature rise of the stator winding of a high-voltage a.c. machine, by measurig-the resistance of that winding under load by means of Kelvin bridge. The method discussed herein has the following special features:1) The installation for measurement is at zero potential, so that safety is assured in operation,2) By taking appropriate measures, disturbance of the a.c. components is Kept away from the bridge circuit, so that the installation of a complicated filter in the galvanometer circuit can he omitted. While the galvanometer still operates steadily.3) A unified method for choosing measuring elements can he applied to various ratings of machines.4) High accuracy of measurement is assured. The maximum error of resistance measurement is within 0.3%, if proper measuring elements were chosen.In the paper the result of measurement and its error are analyzed.

This paper gives the result of a special study of the stability sliding in rock mass on the right abutment of certain reservoir. The breaking face in landslide mass is assumed to be inclined. The ultimate equilibrium of wedge shaped mass is used to calculate the position of breaking face and the sliding force. Through the present calculation of rock mass stability, it is considered that the angle 6 between the force acting on the breaking face and the normal direction of the face would be more appropriate...

This paper gives the result of a special study of the stability sliding in rock mass on the right abutment of certain reservoir. The breaking face in landslide mass is assumed to be inclined. The ultimate equilibrium of wedge shaped mass is used to calculate the position of breaking face and the sliding force. Through the present calculation of rock mass stability, it is considered that the angle 6 between the force acting on the breaking face and the normal direction of the face would be more appropriate to take the angle of internal friction of rock. Finally, the method of equatorial horizon projection is used to analyze and calculate the sliding force and the resisting force in space. Based upon the, results of present calculation, appropriate measures have been proposed, and accordingly are adopted by the engineering projects. To the further verification of these assumptions and results of calculation, plane model stability tests of rock mass consisting of blocks, which stipulated the engineering geological condition of this project have been made. It is fully proved from the test results that the proposed assumptions and method of calculation are close to reality.

Propagation by grafting is an effective means of protecting watermelon-from soil borne diseases and shorten the rotation cycle.An experiment using 3 varieties of Cucurbita moschata,C.maxima and eagenaria lecantha as stocks was carried out to compare their compatibility and also their effect,on yield.It was found from the results that the lagenaria leucantha stock had the highest compatibility,and Cucurbita moschata stock the poorest.Owing to the fact that the root system of the grafted seedling extended extensively...

Propagation by grafting is an effective means of protecting watermelon-from soil borne diseases and shorten the rotation cycle.An experiment using 3 varieties of Cucurbita moschata,C.maxima and eagenaria lecantha as stocks was carried out to compare their compatibility and also their effect,on yield.It was found from the results that the lagenaria leucantha stock had the highest compatibility,and Cucurbita moschata stock the poorest.Owing to the fact that the root system of the grafted seedling extended extensively and had strong fertilizer uptaking ability,there were yield increases in varying degree.Results also showed that for the seedless watermelon and tetraploid watermelon,grafting on even more significant yield-increasing effect.The grafting method used was top-grafting,and 600-800 plants could be grafted each person per day.If appropriate measures such as maintain-ning the proper temperature and moisture and shadimg were taken,more than 90% of the grafted plants might survive.
