Aiming at researching on the theory of the shaft-kind parts form error evaluation and its application, on the basis of the analysis for the geometric model of the roundness error and cylindricity error, the linear programming models of the enclosure evaluation were proposed. According to the features of the proposed models, the solution of the optimization algorithms of linear planning was discussed to obtain accurate evaluation results.

In conclusion, we should keep in mind the possibility of epiglottic hemangioma when confronted with a common epiglottic mass. A hasty intubation, biopsy, and excision can be dangerous. To arrive at an accurate diagnosis and the appropriate treatment, detailed pre-operative evaluations, including magnetic resonance images and angiography, may be needed for differential diagnosis in selected cases.

For example, blood urea concentration as an accurate measure of kidney function and the concept of extrarenal azotemia were first reported at that time.19 It was then believed that the kidney expended considerable energy to excrete urea into the urine and that moderate restriction of protein was beneficial to human patients as contended by Addis.20 This concept fell out of favor in human medicine when it was realized that renal work is tied closely to active sodium reabsorption and that urea is passively handled.

A structured grid partitionfor full scale coal fired tangential utility boiler has been given in this paper. It hasa small amount of grids and can decrease false diffusion effectively as it is inagreement with fluid flow direction. Accurate simulating results can be gainedwith the grid partition. Inverse flows are captured near the wall at four corners incombustion simulating through the above grid and temperatures simulating agreewell with them measured.
