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.

The area is small to the highest ( conversion efficiency 13 - 15%, some have achieved more than 20%) of monocrystalline silicon solar energy cell conversion efficiency, and output power is big, and stability is good, grows ( generally can reach more than 20 years ) service life, but the raw and processed material cost height, the weak light specific property is wronger, and production technology is complicated, hence the selling price is also higher; The polycrystalline silicon solar energy cell is basic identical with the function characteristic of monocrystalline silicon solar energy cell; The conversion efficiency of non- brilliant silicon solar cell than hangs down ( simples about 6 - 8%), the area is than greatly, but because of his raw and processed material cost than hanging down, can be easy to big area industrialize production, what will have hope to be used the generally big area to generate electricity from now on most will be this kind of application that battery is along with manufacture technique and new material, in a single day the practical package photoelectricity conversion efficiency of its big area achieves more than the 10-15%, and the price of every tile electric power-generating equipment is fallen 1 - 2 U.S.dollar of time, and just is enough to that the solar energy cell efficiency that big area the getting extensive use will constantly replace in now convention certainly special use and the laboratory of sources of energy s will high get many.

单晶硅太阳能电池转换效率最高（转换效率13～15%，有的已达到20%以上），面积小，输出功率大，稳定性好，使用寿命长(一般可达20年以上)，但原材料成本较高，弱光特性较差，生产工艺复杂，故售价也较高；多晶硅太阳能电池与单晶硅太阳能电池的性能特点基本相同；非晶硅太阳能电池的转换效率较低（约6～8%左右），面积较大，但因其原材料成本较低，可便于大面积工业化生产，今后最有希望用于一般大面积发电的将是这种电池。随着制造技术和新材料的应用，一旦它的大面积实用组件光电转换效率达到10-15%以上，每瓦发电设备的价格降到1～2美元时，便足以大面积得到广泛应用并将不断取代现在常规能源。当然特殊用途和实验室中的太阳能电池效率要高得多。

As a result, it is convenient for the recognition system to use the simple linear classifier to segment the sample space, so that the accuracy and distortion invariant ability can be easily achieved. The classification structure of a bifurcating tree is utilized to decompose the classification problem of multi-classes to the multi-stage classification of two classes, which simplifies the design of the classifier, and improves the searching efficiency as well. A gray-scale analysis based method for extracting features from optical correlation result is proposed.
