On the basis of planting trees and grass on civic waste disposal ground for restoring vegetation, the nutrient elements absorbed by vegetation in landfills are analyzed and examined. In utilization factor, organic composition is 70.28%, N is 60.29%, Y is 81.85%, K is 88.07%, and beneficial ingredients accelerate the plants growth.

The effects of the Average Processor Utilization Factor and the Network Bandwidth on the number of solutions found are shown and discussed through systematic sets of examples.

In particular, the PUT solutions always make the server work at a utilization factor that is no less than that of the PAC solutions.

In the problems bounding the utilization factor of the queue, the solutions are given by essentially linear programs, while the problems with mean queue length constraints are linear programs if the service is exponentially distributed.

We derive a closed-form formula for the expected fraction of busy servers at any time in terms of the number of servers and the utilization factor (defined as the arrival rate times the mean service-time duration).

The relations between the physicomechanical and geometric parameters of the composite are obtained in the form of a system of inequalities, satisfaction of which ensures the obtaining of a high-strength material with a given utilization factor.

A resonable method to estimate energy utilization is suggested by the author who point out the way to improve energy utilization. The author cites a heat energy utilization factor which distinguish reasonable and unreasonable use in energy system. This probably leads to adopts a system combining heat and electrical energy generation. The heat energy utilization factor is originated from the concept of exergie and simplified on the basis of the second law of thermodynamics which is believed to be...

By mathematical analysis, functional formulas of the kiln type modulus M_K relevant tomean intensity of heat transfer((Q_K)/(LD~(1.5)_t), heat utilization factor U_K and temperature of theexit gas of the kiln t_(Exit) have been established. It is stressed that the exit gas temperature of the kiln is the predominant boundarycodition and that the key to match the preheater with the kiln is to derive reasonablekiln type modulus M_K and a system mudulus M. By introducing the heat required to form the clinker and that transferred to the mate-rial, formulas for calculating the producing capacities of various dry-process rotary kilnscan be established.

This article is written in an attempt to describe the utilization factors and characteristics of the literatures cited in the scientific papers published in Fu- zhou University Journal after it resumed publication in 1978. The preliminary conclusion is drawn from the citation analysis based on samples taken from the bibliographies of these papers. The numerical range of the literatures cited in a single one of the papers is from O to 18 and six on an average. 44.4% of all citations attributes to the literatures in English, constitutes a major portion. of the total citations 76.45% goes to the cita tions from literatures from foreign countries, and the rest to the country's own literatures. The information sources, to a greater extend, are English books and jour- nals, while a lesser part comes from lectures, degree-winning papers, text books, internal reference materials, samples and information of products, etc. All these show, on their own merits, the University's efforts on combining theory with practice, and teaching with research, which reflects the objctive reality of the development of science and engineering. Again, the faculty has an eye for the world's now development in science and engineering, so 78% of the citations are from the publications of the re- cent twenty years. It is proper to say that the statistical data are handled by strict hands, and the results of study of this paper are thus reliable.
