另外针静电分离对废旧电路覆铜板的分离纯度高而产量比较小，我公司开发的多滚筒静电分离机和根据粉碎后的电路板中铜粉与环氧树脂粉的密度比重差距比较大的原理研制的废旧电路板气流分选机解决了分离产量问题。

The resection electrode types include: a hand-crafted, temperature-resistant tungsten wire-cutting loop; a coagulating perforated resector that provides a 40% greater coagulation zone than standard cutting loops and performs cutting and coagulation simultaneously during tissue resection; a dimpled vaporization roller that offers a smoother area of vaporization than a grooved roller while providing deep-tissue coagulation; a roller ball and roller barrel, which are used for coagulation and ablation of soft tissue in the bladder and prostate (the roller ball may also be used for endometrial ablation in the uterus); and a Collings knife that allows urologists access to all areas of the prostate and is most commonly used for ureteral meatotomy and transurethral incision of the prostate.

切除电极包括：手动操作、耐受高温、钨丝切除线圈；凝固穿孔前列腺切除器，比标准切除线圈的凝固面积大出40%，能够在组织切除过程中同时进行切除和凝固；一种漩涡汽化转子，比槽式转子提供更加平滑的汽化区域，同时产生深部组织凝固；一个转子球和转子滚筒，用于膀胱和前列腺软组织的凝固和汽化(转子球还可以用于子宫内膜的消融)；一个Collings刀能够帮助泌尿科医生进入前列腺的所有区域，通常用于输尿管切除术和经尿道前列腺切开。

The rotation of the drum produces a relative motion between the filtering screen and the surrounding water making the filtering screen self-cleaning. Nauplii and rotifers thus could be concentrated at high speed to a high density with little damage.

滚筒的旋转会在滤网与周围的水体间产生相对运动而使得滤网面自净，丰年虾无节幼虫与轮虫因此可以在高速下被浓缩到高密度而不会有太大的损伤。

The continuous operation of the plant has been extended through the improvement in process and equipment, and the excessive workload of the prilling tower has been overcome.

This thesis studies systematically the mechanics problem of the large-torque pulley of belt conveyor.

本文系统地研究了带式输送机大扭矩传动滚筒的力学问题。

U Directly connected to the driven roller or rollers of large diameter, the total elimination of belt slip, and ensure their close contact in the belt

u 直接连接在从动滚筒或大直径的托辊上，彻底消除皮带打滑，保证其于皮带紧密接触

Because you can use a larger force of nano-imprint lithography, so you can get a better image transfer, the DB methods and adopting a single rubber roller business card printing and membership card making business card printing and membership card is very similar to making machine, such as the Heidelberg fast D146／4 business card printing and membership card-making machine, and Indigo Omuins business card printing and membership card that is used in making machine called a color couplers (One-Shot color) technology.

由于可以采用更大的压印力，从而可以获得更好的图像转移，这种DB方法与采用单一橡皮滚筒制卡和会员卡制作的制卡和会员卡制作机非常相似，如海德堡快D146／4制卡和会员卡制作机，也与Indigo Omuins 制卡和会员卡制作机中使用的称之为一次成色(One-Shot Color)技术相似。

The driving drum, the important transmission part in belt conveyorsystem, is often under complex conditions and easily damaged when design parameters are notcorrect. And the capability and reliability of belt conveyor is mainly determined by theintensity and stiffness of the key parts.

传动滚筒是带式输送机的重要部件，承受复杂载荷，一旦设计参数选取不当，很容易在使用中失效，对输送机整体性能和可靠性影响很大。
