The fundamental problems of TOF SIMS applications to the hydrocarbon generating study of source rocks, such as the techniques of sample preparation, the relationship between the abundance and the content of fragment ions, and the necessity of the high resolution of TOF SIMS were discussed.

This paper studied the procyanidins double-coated microencapsulating technology by double emulsion-spray drying, using soybean protein isolated, malt dextrin, sunflower seed oil, emulsifier et al.

White light-emitting diode was obtained based on polymer bilayer structure of poly(N-vinlycarbazole)(PVK) and green light-emitting copolymer(PFSeH) of 9 9-dioctylfluorene(DOF) and selenophene(SeH).

A numerical model for bilayer organic light-emitting diodes (OLEDs) is developed under the basis of trapped charge limited conduction.

Study of Double layer Inclinde-Tubes in a Settling Pond;

A type of double layer suspended spiral inductor was fabricated by the MEMS technology,and the performances of the inductor were measured at 0 05～10 GHz,and the effects of micro line width to Q-factor and the inductance were also studied.

Based on the structural features of a DV tape package and the characteristics of raw material,a set of hot-runner injection mould with double-layer and four-cavity in a layer was designed for forming the package.

The research status of electroless Ni–P composite plating on magnesium alloy was introduced, including the electroless double-layer composite plating, electroless multicomponent alloy composite plating and electroless powder composite plating.

The results indicate that the double-layer type Absorber may improve the Absorbing property of the CNTs composites at C1 band,which made of surface layer of CNTs coating,bottom layer of dielectric composites with low dielectric constant,high intrinsic impedance.
