均匀分布

Whether the inner cylinder is drilled or not do not affect obviously the measurement accuracy. The accuracy of the drilled outside cylinder is higher than the undrilled ones, and the drilled holes are better to be equally distributed, further more, the number is less than 36 with the diameter of 3mm. The sealed outside cylinder can lower the measurement accuracy. The thinner material of sealed inside cylinder is and the more ventilative function is, the higher accuracy will be achieved. Moreover, when the space between inside and outside cylinder is smaller, the measurement accuracy also becomes higher.

结果表明：各处理精度均较高，最高达97.40%；内筒打孔与否对测量精度无显著影响；套筒打孔的处理比不打孔的处理精度更高，且孔洞适宜均匀分布，但数目不可过多，直径为3mm时不宜超过36个；套筒封底会降低测量精度，内筒封底材料越薄、透气性能越好精度越高；内筒与套筒的间隔较小时精度更高。

In order to solve this problem, an improved pyramid technique based on fuzzy clustering is put forward. This new strategy uses a certain fuzzy clustering scheme on the original data sets at first, and then it applies pyramid technique on each cluster. By this means, the pyramid technique can be available in not only uniform data sets but also ununiform data sets.

由于该类轧辊工作层基体组织内除含有碳化物和莱氏体外，还存在均匀分布的球状、团状、蠕虫状或片状石墨，正因如此，除自身具有较好的耐磨性外，还具有较好的抗剥落性、抗热裂性。

Isogram addition with line, histogram, and Lorenz plot is latterly realized in HBACIS so that the results of the inquiring, calculating and analyzing of the climate information can be visually displayed. The successful exploitation of HBACIS shows that the B/S system adopted JSP can totally satisfy the requirement of the agricultural climate information system. For one thing, JSP with the characteristics of high efficiency and security, multiplatform and expansibility, basing on the object oriented language-JAVA, can be sustained widely, and is easy to exploit and maintain. The JSP tags can be extended and the components are reused. For another, the client side of the B/S system is all applied with the browser as the interface, which is very simple and wieldy.

The invention discloses an electrochemical method for preparing a hydroxylapatite particle thin coating on the surface of a metal implant, which comprises the following steps: electrolyte is put into a container equipped with a constant temperature heating system and heated to be 30 DEG C to 95 DEG C, and then the temperature is kept; platinum is taken as the anode and evenly distributed around the container, and the metal implant is taken as the cathode, put in the middle of the container and totally soaked in the electrolyte; DC voltage of 2V to 4V is added between the anode and the cathode, the surface of the metal implant has cathode reduction reaction, the pH value is increased and the supersaturation degree of the hydroxylapatite is also increased, so as to crystalize on the surface of titanium; after 0.5h to 5h of deposition, a layer of hydroxylapatite particle thin coating which can be excellently adhered to the matrix metal is formed on the surface of the implant.

本发明公开了一种在金属植入体表面制备羟基磷灰石颗粒薄涂层的电化学方法，在装备了恒温加热系统的容器中装入电解液，并将电解液加热到30～95℃恒温；将铂作为阳极均匀分布在容器四周，金属植入体作为阴极置于容器中间，完全浸没在电解液中，两极之间加直流电压2～4V，金属植入体表面发生阴极还原反应，pH值升高，羟基磷灰石过饱和度增加，从而结晶在钛金属表面；经过0.5～5小时沉积后，在植入体表面即可形成一层与基体金属结合优良的、薄的羟基磷灰石颗粒薄涂层。
