1.large-flowered wild twining vine of southeastern and central United States having pale blue flowers.
2.European annual with pale rose-colored flowers; cultivated flower or self-sown grainfield weed; introduced in North America; sometimes classified as a soapwort.
3.leafy wildflower having fragrant slender white or pale pink trumpet-shaped flowers; southwestern United States and northern Mexico.
4.Any of several woody, usually prickly dioecious vines of the genus Smilax, having greenish, unisexual flowers, heart-shaped leaves, and usually bluish to black berries.
5.tuberous or semi-tuberous South African begonia having shallowly lobed ovate leaves and small white flowers.
6.In order to improve the prediction of numerical tidal model in continental shelf, the open boundary conditions are optimized by assimilating the observed data into the model in which the adjoint method, based on optimal control theory, is used. The nonlinear shallow water equations are considered in which horizontal kinematic nonlinearities, nonlinear bottom friction and horizontal eddy diffusion are included.
7.Abstract: Through analysis and comparison of the influences of the construction of seal grooves, pressure and rotaion speed on the property of mechanical face seals w ith deep and shoal grooves, this paper aims at helping working staff in the field of mechanical seal get a better and thorough understanding of the seal and facilitates its design and models selection.
8.Moreover, by dividing the hydrogeological stractural layer, and infiltration and seepage systems, distinguishing hydrochemical anomalies of shallow groundwater and deep groundwater this paper expounds hydrogeological conditions and hydrogeochemical features of the Kailu basin and their effect to the development of the interlayer oxidation zone, predicts two prospective areas for in-situ leachable sandstone-type uranium deposits, and finally proposes the Daodemiao area as the most favourable metallogenic target for uranium ore-formation.
