The thermal conductivity of a system of tetrahydrofuran clathrate hydrate-nanoparticles (carbon nanotubes and copper nanoparticles) was measured under different temperatures (258.15–270.15K), different nanoparticle mass fractions (0.1–10wt%), with and without dispersant (sodium dodecyl sulfate), and different nanoparticle dimensions (25nm and 50nm copper nanoparticles). The results indicated that...
516 Species (including subspecies, varieties, and forms), 167 genera and 58 families of lianas were found in Hainan Island by field survey and data examination. According to the texture of their stems, the lianas in Hainan could be divided into 3 kinds: 387 species of woody lianas, 108 species of herb lianas, 21 species of climbing shrub lianas. The paper reviewed the development and utilization of...
Purple coneflower (Echinacea purpurea (L.) Meonch), a Compositae herb, is known for its immunostimulant and anti-inflammation bioactivities. In order to improve the micropropagation efficiency of this plant, the effects of Iodine and light intensity on in vitro culture of the leaf, petiole, and root explants and on regenerated bud's growth of this plant were tested. Results showed that certain concentration...
To explore the genus Bougainvilleaclassification criteria, comparative analysis of 15 morphological traits collected 18 varieties of Bougainvillea, in order to provide a reference for the promotion of Bougainvillea cultivation, breeding and classification, identification and other research. Q-type clustering results showed that 18Bougainvillea varieties can be divided into 3 categories, including...
Porous polyethylene with nanofiber structure in the form of discrete, freeflowing, micron-sized spheres was formed in high activity by ethylene polymerization with porous polymer supported Ziegler-Natta catalyst. Such versatile porous support catalyst played as a template in two levels. One level is the whole support beads, which resulted in the porous polyethylene spheres. Another level is the porous...
The technology of effective visualization for massive vector data of polygons is a key and difficult-solving problem in the field of Digital Earth and Virtual Reality, etc. In this paper, the technology of rasterization for vector data, raster and vector data integration, and LOD were applied on the digital earth platform. Based upon OSG 3D Engine and ArcEngine, the efficiency of massive polygon data...
In order to improve the testability of electrical system of the armored vehicles of the PLA, the author of this paper elaborates on the concept of DFT (design for test) in designing the fire extinguishing and explosion suppression system of armored vehicles, analyzes the structural characteristics of the system and the test strategies of DFT and puts forward two effective strategies on fault diagnosis...
