The influence of different pressure, temperature and flow of CO_2 on extraction yield of the lacquer wax(oil) in kernel was also studied by orthogonal experiment. The optimum conditions are 25 MPa,35℃ and 1 kg/(h·g) in the discharge of CO_2 to lacquer seeds.
The nearer to the surface or the kernel of the grain,the more remarkable the effects were. The sensitivity could be decreased if the doping region was near the iodide. The best doping amount was 1×10~(-6)mol/molAgNO_3.
The kernel of a certain derivation of the polynomial ringk is shown to be nonfinitely generated overk (a field of charactersitic zero), thus giving a new counterexample to Hilbert's Fourteenth Problem.
First we show that the representation ofG×G on eachG-biinvariant irreducible reproducing kernel Hilbert space in Hol(D) is a highest weight representation whose kernel is the character of a highest weight representation ofG.
Using the scalar automorphy kernel ofD, we construct a ?*,G-invariant kernel onD×D×D.
Taking a specific determination of its argument and studying its limit when approaching the Shilov boundary, we are able to define a ?-valued,G-invariant kernel for triples of mutually transversal points inS.
