This paper proposes a metalanguage TrapML for transformational programming, which is designed based on the analysis of its design principles, structures and functions. It has the facilities to describe the syntax of object languages, the set of transformation rules and strategies. The behaviour of transformation systems can be conveniently expressed. Both accurate and vague strategies can be written in TrapML. Metaprogram is of higher reliability.

Passive location and tracking (PLAT) of a moving emitter can be implemented by multi-sited observers or by single maneuvering observer using DOA measurements only. In this article, the principle and method of passive location and tracking of a moving emitter by a single non-maneuvering observer using DOA and TOA measurements are presented and described. computer simulation of PLAT of a moving emitter in two dimensional plane was implemented. It is shown that convergent and accurate tracking data can be obtained.

A microcomputer software determining the crystallite orientation distribution functions (ODFs) and inverse pole figures of hexagonal materials with or without orthorhombic physical symmetry has been worked out the first time. The texture measurements and the ODF calculations were performed for a multidirectionally cold rolled α-Ti alloy (TA7) sheet by the application of this software. It is shown that the rolling planes of most grains in the sheet tend to be parallel to (0001) with a deviation to the extent of 40° and is shown a predominance of the orientation zone containing (1016), while the rolling directions are, as a whole, uniformly distributed along all the directions over the rolling planes. Of all the texture components, (2¯117) [01¯10] is slightly stronger than the other.

An in-situ end-point detection technique for ion-beam etching is presented. A laser beam of the same wavelength and polarization as those in the intended application of the grating is fed into the vacuum chamber, and the beam retro-diffracted by the grating under etching is extracted and detected outside the chamber. This arrangement greatly simplifies the end-point detection. Modeling the grating diffraction with a rigorous diffraction grating computer program, we can satisfactorily simulate the evolution of the diffraction intensity during the etching process and consequently, we can accurately predict the end-point. Employing the proposed technique, we have reproducibly fabricated multilayer dielectric gratings with diffraction efficiencies of more than 92%.
