The specimen horizontally into two of the instrument, sample between the edge of the circular underpan between the minimum distance of not less than 50-mm, measurement should be gently 2 ~ 3 mm/min will activities on blank sample in order to avoid any impact, and make sure the piece and thickness measurement plane parallel.

将试样水平地放入仪器的两个平面之间，试样的边缘与圆形底盘边缘之间的最小距离不小于50mm，测量时应轻轻地以2～3mm/min的速度将活动平面压在试样上，以避免产生任何冲击作用，并保证试片与厚度仪测量平面的平行。

The changes include:(1) Put the urediniospores into the tube with two steel balls and 1. 6 g/L Chelex-100,the uredinia may be picked up with airing host tissues.(2) Add KOH into the extraction buffer instead of NaOH and vortex the tube violently for 30 min.(3) Prick a hole under the bottom instead of picking out of the steel balls, then centrifuge the tube to toss the liquid into the sheathed tube.

改进的 内容包括：(1)在有二钢珠和1.6 g／L Chelex的离心管中加入夏孢子，夏孢子可以来自带有风干寄主叶肉组织的夏孢子堆；(2)在离心管中加入KOH而不是NaOH，然后剧烈斡旋30 min；(3)将离心管管底穿一小孔，套上一新离心管，短暂离心甩出内容物。

To have the level of fourth-generation technology, thanks to good fortune by the German-made automatic winding machine AC338 for example, with the third-generation type of comparison, the practical winding speed of nearly 30 percent, most can be as high as 2 000 m / min;筒纱quality increased yarn Uster CV value of the two machines are basically the same though, but the quality of yarn, such as details of 1000 meters from 14.5 to 12, 17.24 percent lower; km thick section from 134.3 to 121.7 , 9.38% lower; Neps kilometers from 121.6 to 115.5, lower 5%; 3 mm in length Hairiness (months / 10m) from 135 down to 102, reduced 24.4%; 14.36% increase in production; production efficiency 8.5%, not筒纱the use of high-quality, the following procedures brought about by economic interests.

以具有第四代技术水平的，由德国赐来福公司制造的AC338型自动络筒机为例，与第三代型机比较，实用卷绕速度提高了近30%，最可高达2 000 m/min；筒纱质量大幅度提高，乌斯特条干CV值两机虽然基本相同，但纱的质量如千米细节由14.5降至12，降低了17.24%；千米粗节由134.3降至121.7，降低了9.38%；千米棉结由121.6降至115.5，降低了5%；3 mm长度毛羽(个/10m)也由135降到102，降低了24.4%；产量提高14.36%；生产效率提高8.5%，这还不算使用高质量的筒纱后，后道工序所带来的经济利益。

Firstly, A precise batch-distilling tower, which would be adaptable to operate in industry or middle scale experiment, has been designed and set up. The optimized operation conditions of reflux (80?1), vaporing quantity ( 9~10 mL?min-1), and raw material concentration (60% mass of 2-methyl-1-butanol) were found.
