It is concluded that the precision of these points is attenuated equidistantly as concentric circles. Its center is the weighted average of the coordinates of known points with the radius determined by the precision, the quantity and the distribution of known points. The precision of station points is almost independent of intersection angle, and the precision of known points is almost independent of station point. In some circumstance, the detail points may be more precise.

Certainly,--and we make no attempt to dissimulate the fact,-- the observing physiologist would have beheld an irremediable misery; he would, perchance, have pitied this sick man, of the law's making; but he would not have even essayed any treatment; he would have turned aside his gaze from the caverns of which he would have caught a glimpse within this soul, and, like Dante at the portals of hell, he would have effaced from this existence the word which the finger of God has, nevertheless, inscribed upon the brow of every man,--hope.

In the aspect of experiment research: for engineering ceramics such as ZrO2^Si3N4experiments are carried out by a diamond face mill cutter. Cutting force and machined surface roughness are measured, they indicate:(1) Based on the experiments of scratching and ultra-precision face-milling, it is considered that micro-milling depth is the most important influence factor to realize brittle/plastic transition.

The aniline HDN was strongly stressed by the presence of quinoline and DHQ and the HDN of quinoline proceeds exclusively via a pathway which involves fully saturated intermediates on the MCM-41-supported nickel phosphides. The HDN activity of nickel phosphide catalyst was dramatically reduced by the presence of H2S and DBT, probably due to the strong adsorption of H_2S and DBT on active sites which inhibited the adsorption of quinoline.
