The authenticity - the true reflection of accounting information - should be unified among rationality, legalization, objectivity and equity and shown the character of relativity and development.

By use of the proposed algorithm the reliability evaluation of a certain simple power system under different operating states is conducted. The results show that real-time operating conditions greatly impact the reliability level of power system, and the proposed algorithm can truthfully reflect the reliability level of power system in real-time operation state.

Three-dimensional model was built for second regression calculation to reveal the shrinkage process of body,the best equation obtained was y=A+Bx+Cx2,The calculation was compared with experimental results.

1) when building the model , we ought to the entirety be consider model and the appropriate modeling method, accords with the project model to the full and will be convenient for that the calculation is analysed , and hence when establishing finite element model , in order to reveal mechanics characteristic and the smallest solved time we simplify the model.

Objective To analyze the uncertainty in detecting the chlorine in drinking water by ion chromatography, find out the factors which influence the uncertainty, evaluate the uncertainty and give out the uncertainty of evaluation which faithfully reflects metrical credibility and accuracy.

This paper makes a research on the management network of physical education in rural area of Anhui Province in several aspects,such as,the main sports forms,sports facilities,consumption of sports and so on.

These results suggest that the traditional designations of plantain landraces based on morphotype do not provide a true reflection of overall genetic divergence.

This is probably a true reflection of the different vulnerability of these groups to predation and it may be caused by the different ways in which these fishes use the coral substratum.

MRI and CT give a true reflection of the tumor dimensions.

This is thought to be a true reflection of the variation in activity between closely adjacent cells in this part of the stem.

It is suggested that the classical bell-shaped curve is due, at least in part, to an auxin-sucrose interaction, and that it is not a true reflection of the kinetics of auxin-induced elongation.

The treatment to set the engine body in two pins is comprehensively used on engine body processing line. Errors produced and the width of diamond shape pins (the pin cut in both side simultaneously) are usually determined by the max—therein method. It does not act in accordance with practice. Another method to determine errors produced and the width of diamond shape pins was presented in "Communication of Assembling Machine Tool No.7 1979". Simply it is but a statistical method. However, the author applied this...

The treatment to set the engine body in two pins is comprehensively used on engine body processing line. Errors produced and the width of diamond shape pins (the pin cut in both side simultaneously) are usually determined by the max—therein method. It does not act in accordance with practice. Another method to determine errors produced and the width of diamond shape pins was presented in "Communication of Assembling Machine Tool No.7 1979". Simply it is but a statistical method. However, the author applied this concept in conducting the formula was wrong. In this paper, general formula has been directed by statistical method. The formula could be used to determine errors produced and the width of diamond shape pins. The results are tabulated for reference.

This paper describes the investigation into the calculation of the kinematics and dynamics of main and articulated connecting rods of diesel engines. It is known to all that the swing motion of these rods is very complicated. As to the customary type, side-by-side type or fork type connecting rod, each of them is considered as a specific case. Formulas for calculating the kinematics of any particle of the connecting rods and the inertia of any local minimass are derived. Hence, the lateral push forces acting...

This paper describes the investigation into the calculation of the kinematics and dynamics of main and articulated connecting rods of diesel engines. It is known to all that the swing motion of these rods is very complicated. As to the customary type, side-by-side type or fork type connecting rod, each of them is considered as a specific case. Formulas for calculating the kinematics of any particle of the connecting rods and the inertia of any local minimass are derived. Hence, the lateral push forces acting on pistons and the loads on piston pins, crankpins and their bearings are calculated according to the gas pressure and the piston inertia. The forces acting on the connecting rod bolts and on the parting of big-end bearings are also shown clearly.The method introduced in this paper gives more reliable boundary conditions for the calculation of strength, balance and vibration of any diesel engine.The authors recommend that it has to resort to the elastic contact theory to analyse the load distribution on various bearing surfaces in order to take into account the elastic deformation.

This paper proposes a new operating reliability index—operating risk—employedin the power system.That is the probability of power insufficiency in a given timeinterval owing to the outage of part of the generating units in a system whosespinning reserve is limited.For this purpose,two measures arc introduced—theFirst Outage Replacement Rate and the Start Period Outage Replacement Rate.Theproposed index can reveal the operating reliability of a power system more accuratelythan does an ordinary one which is the...
