杂志也使年轻导演二人只字不提，是这样说：这项技术的rawness意味着它不容易掌握，但由于射频说'这是一个活物的不同，每次。

OBJECTIVE: To observe the histologic changes of ACL following reefing treatment, so as to investigate the optimal location to exercise RF reefing on.

目的：观察前交叉韧带不同部位进行射频紧缩后的组织学变化，以确定前交叉韧带射频紧缩的最佳部位。

The last 4 dogs were used to obtain 8 ACLs, out of which 2 ones received immediate RF reefing and the following histomorphological observation and the other 6 ones who received no reefing were taken as the controls.

另外4只家犬取前交叉韧带8条，2条用于即时射频紧缩后的组织学观察，另外6条作为空白对照组不进行紧缩。

Then the blood supply of the ACL of the dog was observed. Another 24 dogs were divided randomly by sortition into two groups, one receiving RF reefing on midportion and the other on amph-portions (amph-portions group).

将墨汁灌注液由远端注入，直至下肢皮肤变成黑色，观察家犬前交叉韧带的血液供应。24只犬采用抽签法随机分为射频紧缩中间部组、射频紧缩两端组。

Producted RF and CRF aerogels by process of sol-gel technics, dynamic-exchange, CO2 supercritical drying, and procedural increase in temperature carbonization methods, which have eximious capability and nanometer network structure; Systemic analysis various factors which effect gel course, such as ratio of reactants and the dosage of catalyst, and probed into the better experiments conditions(the concentration of resorcinol and formaldehyde is more than 2% and the value of R/C is between 50 and 300); During gel course , primary investigated the viscosity curve and particle size distribution of sol-solution, and analyzed the reason of catalyst dosage effects particle size of gel, and confirmed that the up-growth of gel follows the theory of " polymerize increase ".The experiment results indicated that ultrasonic with unvarying temperature disposal shortened gel time and optimized quality of gels, and the factors of ultrasonic effect gel reaction velocity were analyzed; Prepared organic aerogels using compounds of resorcin and hydroquinone substitute resorcinol reacts with formaldehyde the first time, and also optimized the proportion of resorcinol and hydroquinone (the proportion of hydroquinone in 10%～40%).
