The microfabrication and performance NiTi shape memory thin films for microdevice applications were studied by microfabrication processes, which were compatible with those of microelectronics fabrication processes. The sputter-deposition conditions, patterning process, and annealing conditions were investigated. The B2 crystal structures of the thin films can be obtained by annealing at 525°C for 30min. The results from x-ray photoemission spectroscopy indicated that the atomic concentration in the surface of the annealed thin films with preferred structures is comparable with those of the as-deposited films.

The existence and limit behaviour of the solution for a kind of nonlocal nonlinear boundaryvalue condition on a part of the boundary is studied for the heat equation, which physicallymeans that the potential is the function of the total flux. When this part of boundary shrinksto a point in a certain wayt this condition either results in a Dirac measure or simply disappearsin the corresponding problem.

Right before the excystment of an Euplotes encysti-cus sawtooth-like folds appeared among the pellicle plas- malemma, the inner and outer alveolar membranes were still sticking together, and were not distinguishable. Mi- crotubular layers already formed at the sites beneath the dorsal cortical pellicle corresponding to vegetative cells,but they still proceed to be organized on the ventral struc-tures. Cristae, highly-tangled with tubular-type struc-tures, appeared on the mitochondria, and were morpho-logically similar to that of vegetative cells. In the cor-tical ciliatures, such as ciliary shafts, kinetosomes, sur-rounding fibrillar cirral baskets, and attached structures of ciliatures, etc., they are different from those in rest- ing cysts which are degenerated or lost. All the cilia- ture microtubules of ciliary shafts are of the 9+2 pattern,but the microtubule-like structure aggregates at triplet - microtubule centers of many kinetosmes, are still under various stages of differentiation. Microtubules beneath the kinetosomal rows are of a developmentally elongated stage; crowded chromatins of various shapes and sizes are found in macronucleus, but there are no nuclear pores (formed by nuclear membrane as in resting cysts) on the nuclear membrane where these chromatins attached.

Let G be a second countable locally compact groupoid with Haar system {λu}, H be a closed subgroupoid containing Go with Haar system {λuH}. *** introduced the C*-Groupoid dynamic system (G, A, α) and its reduced crossed product Cr.d(G, A) in [2], where A is a C*-algebra, α is the homomorphism G→Aut(A). In this paper the author introduces the C*-groupoid dynamic systems (H, A, α|H) and (H\G2, A, α) induced by (G, A, α) and proves that C~*red(H, A) and C~*red(H\G2, A) are strongly Morita equivalent. Moreover the induced representation from C~*red(H, A) to C~*red(G, A) is got.

Restricted edge connectivity of a graph G is defined to be the minimum size |U| of a set U of edges such that G-U is disconnected and G-U contains no trivial component K1. The high order edge connectivity Ni, i1, is the number of edge outsets of size i. TO determine all Ni, i 1, for a general graph is NP-hard. In this paper, the authors evaluated the restricted edge connectivity and the high order edge connectivity Ni, 1 i -1, for any connected Abelian Cayley graphs explicitly.

The notion of ranking was initiated into control theory by Glad a few yearsago. In this paper we mainly discuss one kind of rankings and study its invarianceproperties. This kind of rankings is closely related to the structure algorithm. The relationsbetween invariants of this kind of rankings and the invariants given by other studies, *** invertibility indices of a system and so on, are examined. As applications of rankings,we deal with some well-known problems in "ranking technique". In this paper we mainlyintroduce a new method rather than solve new problems.
