The separation conditions for the extract of Herba Lycopi was optimized using reverse phase-high performance liquid chromatography(RP-HPLC).

Objective To optimize the separation conditions of fingerprint for Alpinia officinarum Hance by HPLC.

Using high-efficiency liquid trend colour spectrum L-7100, the method of reverse direction couple ion chromatography, analyzed and defined the separate condition of the V c,V b1,V b2,V b6,niacin , five kinds of water-solubility Vitamins use external-label method,established the way of low pressure gradient elution base on the solution of potassium dihydrogen-carbinol,the trend of flow ability.

Pointing out the foult ofliterature 〔1〕～〔8〕,this paper reanalyses the ball dynamicsin a ball mill and forward its new kinamaticallaw ,separate conditions and separate angle , which are differentfrom preuious absolutly .

The improves Malliavin’s uniqueness theorem on the analytic functions in the right half plane,then obtains a generalization of the discrete Phragmen-Lindelǒf theorem under the complex separation condition.

Study on the separating conditions of Ralstonia solanacearum by high performance ion exchange liquid chromatography analysis;

This paper gives the estimate of upper and lower bound for the first two eigenvalues of Sturmm-liouville problem with general separate type of boundary conditions by setting one-one relation between the eigenvalues of Sturmm-liouville problem and the real roots of one kind of equation.
