volume table
3.This article uses fixation swatch founding for second-class investigation to obtain character of 207 sample trees, by which mathematics model of ground diameter volume table of Chinese Fir were deduced by regressing and imitating with five of equations respectively, and used unitary and binary volume tables of timber respectively to reckon an unitary ground diameter volume table, then compared the two ground diameter volume tables, so that a ground diameter volume table of Chinese Fir in Yanping District was compilated to satisfy essentially the precision demand of forestry production, and to serve forestry production.
4.The variable parameter taper equation, which was suitable to Pin us elliottii plantation form changing law, was built with the sample wood datas on the basis of the research of about form shape in the tree mensuration, one-dimensional volume table, two-dimensional volume table, one-dimensional timber-produced rate table for timber assortment, and two-dimensional timber-produced rate table for timber assortment were complied based on the above.
5.Determining the Terminal Radius of Measuring Buret of Drop-Volume by V/r￣3-F Table
9.optimum formula for AbM in shaking flask culture was determined, which consist of 3 % of corn starch, 0.8 % of soybean cake meal, and 0.15 % of wheat bran, and its pH was 5.0. The optimum culture conditions are as follows, temperature 30 ℃, velocity of shaking table 120 r/min, fed volume 50 mL/250 mL and culture duration 7 days.
