For example, alkaline elements can affect diffusion velocity of Zr, Si and O ions although these alkaline elements cannot exist in crystal structure of zircon. However, K rich media and Na rich media exert different effects on the growth of crystal form: in the K rich media, growth speed of prism faces in the vertical direction is much higher than that of pyramid faces, and {111} growth speed in the vertical direction is higher than {311},which decides the formation of bipyramids dominated by {311} pyramids; in the Na rich media, both prism and pyramid grow to a certain extent, but the former is smaller than the latter.{100} growth speed in the vertical direction is lower than {110}, while {111} growth velocity in the vertical diredtion is lower than that of {311},resulting in the growth of the crystal form characterized by {100} short prism and {111} pyramid.
例如,尽管碱性元素并不进入锆石晶格,但它们可以影响Zr、Si、O离子的扩散速度,但是富钾和富钠的介质对锆石晶形发育的影响是有差别的,表现为:在富钾的介质中,将导致柱面的法向生长速度较锥面快得多,而锥面中,{111}的法向生长又较{311}快,由此决定了形成以{311}锥为主的双锥状晶体;在富钠的介质中,柱面和锥面都有一定程度的发育,但前者弱于后者,而柱面中,{100}的法向生长较{110}慢,由此决定了形成以{100}柱和{111}锥为主的短柱锥状晶体。

In this paper RoboCup Mid-size Robot are the object of study from the two sides of the robot system and the system of multi-robot cooperation, the main research results are as follows: First, this paper reasearches the problom of the hardware and software architecture of Mid-size robots. According to the real-time requirements of the competition, the paper designs the mechanism of omni-direction wheels, which achieves a great improvement on the traditional mechanism of two wheels robot, and a more flexible response. This mechanism can adapt well to the increasingly rapid pace of the competition. In allusion to the mechanism of omni-direction wheels, this paper designs the electrical control system of three nodes in the bottom, which could communicate fast to the laptop with serial port and match the real-time requirements well. According to the problom of hitting power and speed of robot when shooting, this paper designes a motor-driven tongue-shaped spring shooting mechanism, which has a simple mechanical structure, smaller space in size and simple control circuit. This shooting mechanism meets the real-time requirements of the competition better.
