When the concentration of the essential oil was 5.00,2.50 and 1.25 mg/L, the non-selective antifeedant effect was 86.70,74.36 and 70.93%,respectively,after 24 h,and was 82.36,71.40 and 60.40%,respectively,after 48 h.
The laser head uses He-Ne laser with output power 2 milliwatts, the collimated laser beam diameter less than 14mm and the rotating speeds 0-500 r/min. The omnisensor is composed of 6 layers with 54 sensitive detectors, which oprating range 150m, the working precision coarse ±40mm, fine ±10mm.
The influence of heating temperature(1 200 ℃,1 180 ℃)of 180 mm cast slab,rolling passes for 2.3 mm hot coil(7 pass and 5 pass),finishing rolling temperature(780～860 ℃)and coil temperature(≤710 ℃)on iron loss and magnetic intensity of 0.5 mm cold rolled non-oriented silicon steel 50W600 has been tested.
Glutathione was representatively selected to test the precision of this method.
The limits of detection (S/N = 3) ranged from 0.70 to 1.18 mg L-1, the recoveries ranged from 87% to 102% and the precision expressed as % RSD intra-day and inter-day varied from 0.9 to 3.9 and 1.2 to 5.6, respectively.
Numerical experiments demonstrate its effectiveness, easy implementation and high precision.
Furthermore, all the states approach the equilibrium in arbitrary precision by choosing some design constants appropriately.
Experimental results show a closed test precision of 98.64 % and an open test precision of 95.01 %.
A Time Domain Characterization of the Fine Local Regularity of Functions
We also show that, if ξ f(ξ) satisfies Daubechies' criterion, then L f(L)δ generates a frame for any sufficiently fine latticesubgroup of G.
Moreover, we show that the ratio of the frame bounds approaches 1 nearly quadratically as the dilation parameter approaches 1, so that the frame quickly becomes nearly tight (again assuming that the lattice subgroup is sufficiently fine).
In particular, if the dilation parameter is 21/3, and the lattice subgroup is sufficiently fine, then the "Mexican hat" wavelet, Le-L/2δ, generates a wavelet frame, for which the ratio of the optimal frame bounds is 1.0000 to four significant digits.
This algorithm involves solving one nonlinear system on a coarse grid and one linear problem on a fine grid.
Consideration was given to the problems of constructing schedules for oil product mixing with the aim of determining the mixing sequence, the times of starting and finishing each mixing, and the amounts of products to be prepared at each mixing.
