The invention discloses a method for manufacturing a precise photoconductive film cavity of backlight modules, which is characterized in that: an ultraviolet laser beam is reflected on a digital micro mirror after being expanded and collimated, the digital micro mirror is controlled according to the shape of a light guide network to be produced, and reflected light etches the light guide network on the surface of an ultraviolet photoresist dry plate via a projection optical system with 4F light paths; the relative positions of the reflected light and the photoresist dry plate are changed in turn to complete the etching of each needed light guide network; and the etched photoresist dry plate is electroformed after the process of surface metallization, so as to obtain the needed light guide film cavity. By inputting the shape of the light guide network via the digital micro mirror and etching the light guide network on the photoresist dry plate directly via the ultraviolet laser, the invention can evaluate the network design and provide sample products in a rapid manner, and improve the manufacturing quality of the cavity; at the same time, the invention is propitious to the manufacture of large-sized light guide plates.

Method for preparing dandelion absolute oil and application of dandelion absolute oil in cigarettes

The invention discloses a method for preparing dandelion absolute oil and an application of the dandelion absolute oil in cigarettes. The method for preparing the dandelion absolute oil comprises the following steps of dandelion raw material obtaining, drying and smashing, solution extracting, extract liquid concentration, cold storage and standing, dewaxing through centrifuge, liquor concentration, freezing and standing and separation, wherein the process of liquor concentration is conducted until no alcohol smell exists, and the absolute oil is obtained after separation. The dandelion absolute oil is applied to cigarette production as spice for the cigarettes. When the cigarettes are burnt and smoked, the smoke concentration is improved, flavor is rich, foreign flavor and stimulation are reduced, and the content of parts of harmful ingredients in cigarette smoke can be reduced. The method for preparing the dandelion absolute oil is characterized in that a refined preparation technology for dandelion extract is provided, through an appropriate separation purification technology, the dandelion extract undergoes refined processing, and therefore the product quality and the effects are improved obviously. The method has the reference value for refined processing of natural spice. The method for preparing the dandelion absolute oil and the application of the dandelion absolute oil in cigarettes have the advantages that production raw materials are abundant and easy to obtain, the production technology is simple and easy to operate, the product quality is stable and easy to control, the production cost is not high, and therefore practical production significance and value are achieved.

Capsaicin beta-cyclodectrin inclusion-compound and liposome and gel of inclusion-compound

The invention discloses a capsaicin beta-cyclodextrin inclusion compound, as well as liposome and gel thereof. The capsaicin beta-cyclodextrin inclusion compound is prepared by the following method: (1) beta-cyclodextrin is dissolved in an aqueous phase and prepared into a solution, and the solution is added with capsaicin or a capsaicin solution so as to obtain a mixed solution of capsaicin and beta-cyclodextrin; and (2) the solution-type capsaicin beta-cyclodextrin inclusion compound is obtained from the mixed solution prepared in a step (1) through at least one treatment mode of standing, heating, stirring, ultrasound or grinding. The apparent solubility of the capsaicin of the inclusion compound increases by 2 to 20 times. In vitro transdermal study shows that the capsaicin inclusion compound can obviously raise the transdermal rate of medicine by 5 to 20 times as compared with cream and hydrogel, and obviously reduce the irritation of capsaicin at skin. Besides transdermal drug administration, the prepared inclusion compound and the inclusion compound liposome can also be orally taken, injected or administrated in bladders. In addition, the invention is simple in production process, and the quality is stable and easy to control.
