查询词典 on the beam

The uncovered tracts and the liver wound surface were managed by some of the methods combined such as high frequency electrocoagulation, titanium clamp, suture, hemostatic gauze oppression, argon-beam coagulation, protein glue adherence, and Endo-GIA switcher. The total operative outcome, operating time, blood loss, postoperative complications and postoperative hospital stay were summarized in order to assess feasibility and safety of the clinical laparoscopic liver resection.Results: 1. Laparoscopic liver resection with clamp dissection method needs only the ordinary laparoscopic equipment. It has a low cost but causes a little more bleeding. 2. Laparoscopic liver resection operated by microwave tissue coagulation method had very little bleeding when dissecting hepatic parenchyma. The operative field is clear and the cost is low. It is a safe, convenient and effective method. 3. Ultrasound dissector is a relatively ideal appliance for laparoscopic liver resection at present because ofless bleeding during operation. But the speed is slow thus prolongs the operation time. Its separating intensity is not strong enough, and it can only be applied to patients without hepatic cirrhosis. 4. Ligsure has clamp dissection and electrocoagulation functions. It can carbonize hepatic tissue including the tracts whose diameters are less than 7mm. It has some advantage in dissecting. However, it has the shortcomings of the clamp dissector during coagulating. 5. Hand-assisted laparoscopic liver resection can make use of the flexibility and feeling of the operators left hand.

结果：1、钳夹分离切肝法不需特殊仪器设备，只要具备常规的腹腔镜器械即可实施，成本低，肝断面较易渗血；2、微波固化切肝法肝实质出血很少，视野清晰，成本低，操作简单，是一种安全、简便、有效的方法；3、超声刀是目前较为理想的切肝器械，术中出血少，但是，切割速度慢，手术时间长，而且，切割强度有限，适用于无肝硬化的肝切除；4、Ligsure具有挤压粉碎及高频电凝止血两大功能，可使包括7~以下管道的肝组织碳化、形成焦痴，具有一定的优势，但是，也存在分离钳电凝止血的缺点；5、手辅助腹腔镜肝切除可以利用术者左手的灵活性及手感，便于术中显露、分离、控制出血等，可随意协助右手及助手的主要操作，缩短了手术时间，大大提高了腹腔镜肝切除的安全性，李朝龙等的改良方法，同样达到了手辅助目的，又节省了费用；6、小切口腹腔镜辅助切肝法可以使用剖腹肝切除常规器械及剖腹肝切除技术，操作简单、可靠，适用于肝左外叶切除及右肝第V段切除；7、Endo一GIA切肝法在离断肝组织的同时闭合管道结构，多用于肝左静脉、门静脉分支、管径较大胆管的切割，缺点是不能用于较厚肝组织的切割，而且价格昂贵；8、临床巧例腹腔镜肝切除均获得成功，手术时间最短1.5h，最长sh，平均125 min，多数在100 min左右，手术出血量最少50 ml，最多500 ml，平均1 78 ml，除2例合并严重肝硬化的原发性肝癌患者术后出现少量腹水，1例术后发生胆漏外，其余无并发症，发生胆漏的1例患者术后住院40d，多数在术后一周左右出院，术后住院时间5一40d，平均gd。

In the laser engineering system,a beam expander and an annular aperture were taken as the equivalent of the Cassegrain telescope system.

在激光工程系统中，把卡塞格林望远系统等效为一个扩束器和环形光阑的组合形式，研究了激光束的光腰半径与卡塞格林望远系统的参数匹配问题。

A CAT scanner, however, uses a beam of X-rays to give a cross-sectional view of a specific part of the body.

然而，CAT扫描仪却可以利用一束X射线照出一幅体内指定部位的断面图。

Typical catamaran will have a beam to length ratio of about 50%; Meaning that a 45' catamaran will be about 22' wide.

典型的双体船的宽长比为1比2。这就说明45英尺长的双体船大约22英尺宽。

Outlines the J2476 electron beam demonstration to use the JG-4 gasification electrostatic deflection cathode ray demonstration tube i.e.

J2476型电子束演示器采用JG-4充气型静电偏转阴极射线演示管。

In cathode ray tube display, the continuation of light emission from phosphor after excitation by the electron beam.

在阴极射线管显示器中，用电子束激励后荧光物质光发射的持续现象。在这些教材中出现过。。。

The secondary backscattered electron current is used to modulate the intensity of an electron beam in a cathode ray tube.

二次电子或背散射电子的电流被用来调制阴极射线管中电子束的强度。

Luminescence evolutions of GaN irradiated by low energy electron beam before and after hydrogenation has been investigated by means of cathodoluminescence, combined with the diffusion properties of hydrogen in GaN.

本文结合氢在GaN中的扩散特性，运用阴极荧光谱，对氢化前后低能电子束辐照下GaN带边发光强度的演变进行了研究。

In 1974, the first such experiment was carried out by Clauser, who reported a violation of a classical Cauchy–Schwarz inequality. In 1977, Kimble ''et al.'' demonstrated an analogous anti-bunching effect of photons interacting with a beam splitter; this approach was simplified and sources of error eliminated in the photon-anticorrelation experiment of Grangier ''et al.

尽管到了二十世纪七十年代支持光子说的物理和化学实验依据已经相当丰富，证据可能还是不能被认为绝对确凿；因为这些实验都依赖于光与物质的相互作用，而一个足够复杂的关于物质的量子力学理论则仍然有可能去解释这些实验现象。

The results show that an electron efficiency over 27% is predicted for suitable dimensions for the complex cavity and magnetic field coefficient and current and the velocity ratio of the electron beam.
