Their body height, body weight and body surface area were 175cm, 60kg, 1.63m2 in average respectively. The rate of working time was 56.41%, that of energy metabolism was 9.13KJ/min·m2. The results showed that physical intensity of the workers in making bricks is of grade Ⅰ-Ⅱ, that of roast process is of grade Ⅲ.

Since production management information system, we can do management ,and execute, running parameter can rejust by random, unproved running operation, and decrease frequency, it is effort to improve production rate of working ,getting major and direct performance.

The experimental results indicated that the condensation heat transfer coefficient increased with the applied voltage when the high-voltage electric field was exerted on the fluid in condenser under the condition of the same heat transfer surface area and flow rate of working fluid.

RESULTS: Before ischemia, the aortic pressure, left ventricular systolic pressure, the maximal rate of left ventricular pressure change (+dp/dtmax and- dp/dtmax), cardiac output, stroke volume, left ventricular end-diastolic pressure, and heart rate of working hearts treated with Sub 10 umol . L-1 for 10 min were increased by 14 %, 17 %, 17 %, 22 %, 15 %, 32 %,- 200 %, and -11%, respectively.

After giving the specific expression pattern of ANN math model of a fluid coupling,the effects of a fluid coupling upon dynamic characteristics of marine propulsion system are in particular described,they are:the effect of different filling rate of working fluid on the dynamic behavior of engagement process of the coupling;

Rock-stability characteristic based on displacement rate of working contour

We show that Alfvén-gravity waves propagating in a gravitationally stratified atmosphere do not suffer damping as a result of the rate of working of the gravity drift current on the electric field of the waves.

It is shown that Ud(Id) ～ aIdb, where b depends on mass flow rate of working gas and time delay between start of gas supply and discharge switching on.

The algorithm provides a high rate of working efficiency in parallel environment with local memory, even if the communication time is considerably longer than the operation time.

This interesting phenomenon may be achieved when the evaporation rate of working liquid is equal to the condensation rate of hot vapor bubbles.

By using the vector and tensor analysis three dimensional aerothermodynamic equations for viscous flow, the deformation and stress tensors, the rate of work done by viscous forces and dissipation function expressed with respect to non-orthogonal curvilinear coordinates are derived systematically in present paper. Different forms of above-mentioned formulas expressed by other coordinate systems are also given in this paper. These formulas are convenient for the computation of the viscous flow in turbomachines....

Investigations were made on the characteristics of paddy-fields in southern China and the current walking ways of plough-harrow unit. According to the targets of evaluating the walking ways of the unit and the researching method, the rates of working-route on several major walking ways of plough-harrow Unit were calculated and analysed theoretically. At the same time, measurements were made on the field work with various plough-harrow units and different fields in the communes, brigades and farms...

According to the targets of evaluating the walking ways of the unit and the researching method, the rates of working-route on several major walking ways of plough-harrow Unit were calculated and analysed theoretically. At the same time, measurements were made on the field work with various plough-harrow units and different fields in the communes, brigades and farms of Fujian and Jiangxi provinces. Combining the theory with practice, a reasonable choice on working ways of plough-harrow unit has been done. Therefore a correct basis for planning farmland on the paddy-fields in southern China is provided.

The influence of various contents of manganese, carbon and chromium, inoculation process, water toughening and age hardening on microstructures and properties of austenitic manganese steels was investigated, and capability of work-hardening, resistance to plastic deformation and resistance to abrasion under non-severe impact condition were emphatically discussed. Experimental results show that impact value of Mn7Cr2 and Mn9Cr2 steels are equal to 8-10 kgf.m/cm~2 and 13-14 kgf.m/cm~2 respectively; as compared...

Experimental results show that impact value of Mn7Cr2 and Mn9Cr2 steels are equal to 8-10 kgf.m/cm~2 and 13-14 kgf.m/cm~2 respectively; as compared with Mn13 steel, rate of work-hardening under non-severe impact condition, original hardness and yield strength of Mn7Cr2 and Mn9Cr2 steels are increased more than 20%, 40-60 HB unit and more than 15 kgf/mm~2 respectively. Consequently, the durability of Mn7Cr2 and Mn9Cr2 steels are superior to Mn13 steel under non-severe impact condition.
