1.Gauss distribution function was utilized to describe the distribution of the mean percentage of the equivalent sphericaldiameter (BSD) of marine phytoplankton.
2.Its dispersibility was the best when pH was about 4.5, the particles were spherical, its diameter was about 20~30nm, the particles’ fringe were clear and its diameter was not change after annealed 500℃ for 4h.
3.Scanning electron micrographs showed that most of Fu GBM were spherical. The diameter of Fu GBM ranges from 0.35～2.17 μm. The span was 0.80. GD and DL were 23.7, 4.86%, respectively.
4.The resulted powder was characterized with Transmission Electronic Microscope (TEM) and X-ray Diffraction (XRD). The particles of nano-crystalline LaF_3 were spherical with diameter of 15nm~25nm and narrow size distribution.
6.There are two morphological types of thisvirus. One is spherical,having a diameter of 40-45 nm,and is similar to Dane par-ticle under electronmicroscope.
此病毒有两种形态:一种是直径为40～45毫微米球形颗粒,外貌与 Dane 颗粒相似,结构清晰;收藏指正
7.The shape of A-type and B-type crystallite is basically spherical, and their diameter is 2~10μm. Their relative crystallinity is 80% and the polymerization degree (DP) of peak values is 14~19.
8.RESULTS:The niosomes were spherical with the diameter over 2.21～6.78 μm and the extent of entrpment of the INH NS was 24.95%. The INH NS was stable for three months when stored in refrigerator or at room temperature.
9.Results:The study results showed that the GBN were spherical with an average diameter of 316.3 nm. The DL and DTE was 3.12% and 91.82%, respectively. 55.71% of adriamycin could be released from GBN over a period of 48 h.
10.2) Nano-particles of CaCO3 and rare earths appeared in spherical powder with the diameter of 40nm and 11 nm, respectively. They have different functions on friction surface, CaCO3 nano-particles work similar to "tiny ball bearing", which can support loads;
