The suggestion of improving the lamination forms and sheet shapes is presented in accordance to the status of the transformer industdry at home and abroad.

Results The sensitivity, specificity and across reaction of DDIA using 10 μl of sample sera were 95.7%, 96.0% and 20.0% respectively and COPT were 72.9%, 100.0% and 0 respectively.

The piece-shaped castings were invested with self-cured resin into the blocks with the volume of 50mm×15mm×10mm, and a 25mm×10mm, round seat was made for each block.

It was suggested that arachidonic acid metabolites PGE 2、TBX 2 and 6 keto PGF 1α existed in Fasciola hepatica flukes and the metabolites may produce some role for the host.

Although these alloys exhibit excellent soft magnetic properties, their thin sheet shape, which is a consequence of the low glass forming ability, limits significantly their engineering applications.

Although these alloys exhibit excellent soft magnetic properties, their thin sheet shape, which is a consequence of the low glass forming ability, limits significantly their engineering applications.

In this case, the initial vortex sheet shape of Figure 4.la was modified by including a longitudinal perturbation.

Pullin formulated the problem in self-similar variables and solved for the vortex sheet shape numerically.

The Table gives the initial vortex sheet shape and circulation density for the three cases presented.

A sheet-current approach to coronal-interplanetary modeling

These currents form the basis for the sheet-current model.

The present aritclc reports a new species of trematode from domestic duck in the small intestine for which the name Psilotrema fukienensis sp. nov. was proposed. Its specific cheracters are briefly geven as follows:The body is linguiform with cuticular spines, 1.6-2.4×0.6-0.78mm (1.78×0.78mm). Oral sucker 0.13-0.18×0.15-0.19mm (0.15×0.156mm). Acetabulum round 0.274-0.35×0.28-0.35mm (0.314×0.32mm). Oral and ventral suckers ratio 1 ; 2.1×1: 2; Prepharynx and oesophagus present; Pharynx strongly developed, 0.093-0.15×0.13-0.16mm....

Acetabulum round 0.274-0.35×0.28-0.35mm (0.314×0.32mm). Oral and ventral suckers ratio 1 ; 2.1×1: 2; Prepharynx and oesophagus present; Pharynx strongly developed, 0.093-0.15×0.13-0.16mm. Testes unequal, anterior testis measures 0.16-0.35×0.22-0.43mm (0.24×0.32mm). Posterior testis 0.19 -0.34×0.23-0.51mm (0.245×0.364mm). Cirrus pouch 0.48-0.67mm in length, with prominent prostate glands. Genital pore sinistal to equatorial level of pharynx. Ovary round, situated submedian-body, The distances of the ovary from the midbody, anterior testis and acetabulum are greater. Ovary 0.104-0.17×0.099-0.18mm (0.12×0.125mm). Vitellaria large and follicular, starting between preacetabulum and equator of acetabulum and extending to-near posterior end. Eggs asymmetrical, 0.103-0.121×0.69-0.083mm (0.113-0.072mm).Psilotrema fukienensis is closely related to P. acutirostris Oschmarin, 1963, P. brevis Oschmarin, 1963, but may be distinguished from body spines, size and shape of body, the size and position of testis and ovary, position of genital pore and size of eggs.The life cycle of Psilotrema fukienensis is elucidated in the present study and all stages are described in detail. At room temperature of 28-32℃,miracidia hatched from eggs after 14-15 days of incubation. The miracidia of P. fukienensis developed into sporocyts and two generations of redia in the snail host, Parafossarulus striatulus. At temperature of 28-35℃, it was found that mature cercaria emerged from its snail host in 45 days after exposure to miracidia. The cercaria may encyst on various aquatic plants, some of cercaria encyst also on the surface of water. The cysts encysting on the surface of water possess infection strongly.Based on the studies of the life cycle of P, fukienensis showed that Family Psilostomidae Odhner, 1913 is closely related to Family Echinostoma-tidae Poche, 1926 and Faciolidae Railliet, 1859. The relationship of threefamilies were briefly discussed. The pathogenicity caused by P. fukienensis is-briefly described.

In this paper,a method of shift of dyadic cycle sequence has been offered in order to optimize the scheme of switching pieces in electromechanically follow-up control system. As a consequence, all the configurations of switching pieces of automatically follow-up shifter will be able to find out when the number of position shiftings Z are given. For the convenience of directly selecting an appropriate scheme, all of the available options corresponding to the number of position shiftings Z, such as the eycle sequence...

In this paper,a method of shift of dyadic cycle sequence has been offered in order to optimize the scheme of switching pieces in electromechanically follow-up control system. As a consequence, all the configurations of switching pieces of automatically follow-up shifter will be able to find out when the number of position shiftings Z are given. For the convenience of directly selecting an appropriate scheme, all of the available options corresponding to the number of position shiftings Z, such as the eycle sequence and especially the numerical combinations of K, are tabulated and appended. The symbol K here is defined aswhere θ0-an unit center angle between two nearby control positions withequal interval on a switching piece;θ-shifting angle from a control end to another;Z-realizable number of position shiftings.The relation between Z and the number of control ends n is presented asZ = 2n-twhere t means the number of codes ought to be removed. Two instances in illustation of scheming are cited.

Based on a series of experiments, formulas are established for calculating the drag coefficients, the velocity dampings and the penetrations into red pine, of fragments of various shapes, including square, triangular, cylindric and spheric fragments. By applying these formulas and the accompanying diagrams and tables, the effective lethal radius for each kind of fragments can be pre dicted and calculated easily and effectively, thus providing a theoretical basis for the optimization of preformed fragment designs....
