This has some disadvantages and this paper reports the experience for colon examination in children with an adult gastroscope instead of an adult colonoscope.

但由于小儿结肠疾患相对成人较少，需行结肠镜检查的患者不到所有患者的1%，由于待检患儿数量少，因此许多开展

Secondly, a commentarial review of this field is given to show the last evolution of it. Although many kinds of useful projective invariance have been derived so far, the sorts of 3D object to which they could be used are still very limited. So there are some needs to develop more powerful invariance for the 3D object recognition. Finally, in the last part of this paper, the future researches in this field are proposed.

0引言 众所周知，3D物体识别是计算机视觉研究的一项重要内容，由于其在军事、工业等社会诸多行业中具有潜在的、巨大的应用价值，半个世纪以来受到各国视觉研究者的广泛关注，并提出了众多的理论和方法川，其中基于几何不变性的3D物体识别方法有助于消除由于观察视角、摄像机参数等

Based on the researches of system factors, system characters and the influence of market structure to market behavior, the chapter points out the characteristics and rules of china bond market system variance. On account of the Promoting Effect Government Dominated behavior, compellent system variance runs through the evolution of market structure and act on it. Although derivational system variance also works, it can't be the dominant because of the long variance time and high cost.

根据制度变迁理论研究债券市场结构的制度成因、特点及其对于市场结构和行为的影响，指出中国债券市场制度变迁的特点和规律，由于在中国债券市场的发展过程中，政府主导行为具有明显推动效应，强制性制度变迁始终贯穿于市场结构演变的过程中，并对其形成重要作用；诱致性制度变迁虽然也穿插其中，但由于其变迁时间长、成本高等特点，无法形成主导力量。

Secondly, starting from different understanding to the benefit of the country, the United States and Japan had chosen different strategies and concrete policy. There were serious defects in American East Asia containment strategy, although it seemed to have clear goal with strong globality and continuality.

美国的东亚遏制战略看似目标明确、整体性和延续性都非常强，但却存在严重缺陷，并由于假设与现实之间的偏差、由于军事手段与经济手段的不均衡而不可避免地走向僵化，最终导致美国国家利益的受损。

Since this is only a small percentage of our total output and because different specificatons of our products are differently priced, we are of the opinion that , in the spirit of conpensation trade,it would be incumbent on you to guarantee that you will accept our countersale products each year to a value not less than our instalment payment to you in the same year.

我们也从贵方来函中获悉贵方仅回购有你们机器翻译所生产的30%的产品，并用机器信用证付款。由于回购部分只占总产量的很小部分，并且由于产品各种规格的价格不同，为符合补偿的精神，我方人为贵方必须保证每年返销的金额不低于我方同年内偿付贵方设备的金额。该跳进将写进我方保函。

In recent years,as the quantity of drinked liquor increased year after year, alcohol has become the primary damnous factor for liver lesion. As the technique of image check-up improved, the diagnosis rate of alcoholic fatty liver has been increased year by year with an increased tendency. Because the alcoholic fatty liver are susceptibler to developed fibrosis and hepatocirrhosis than the unalcoholic fatty liver, it is greater threat to people.

近年来由于人均饮酒量的逐年递增，肝脏的受损首当其冲，加上医学影像检查技术的提高，酒精性脂肪肝的发病率及诊断率逐年增加，有上升趋势，并且由于酒精性脂肪肝发生肝纤维化和肝硬化的进程比非酒精性脂肪肝更快，发生率更高，对人体的威胁也更大。

Hong Bo: External environment can affect Internet company to gain the opportunity of investment really, because economic situation is exasperate,this is, bring about investor more careful, in the meantime, because appear on the market to decrease with the opportunity that buys, invest the possibility decrescent that exit.

洪波：外部环境确实会影响互联网公司获得投资的机会，这是由于经济形势恶化，导致投资者更加谨慎，同时，由于上市和并购的机会减少，投资退出的可能性变小。

Firstly, it is difficult to densify CeO2 based solid electrolyte materials and a sintering temperature above 1600℃is required to prepare dense CeO2 based solid electrolyte materials by the conventional solid-state reaction method;Secondly, doped ceria are brittle materials and have weak mechanical strength, which would be susceptible to fracture due to thermal stresses and mechanical stresses during cell fabrication and operation; Thirdly, electronic conduction will be introduced because of the reduction of Ce4+ under low oxygen partial pressure, which would reduce the output voltage and output power of the cells.

其一，CeO_2基电解质材料难以致密化，用常规的固态反应法制备的CeO_2基电解质粉体需要在1600℃以上烧结才能达到致密化；其二，CeO_2基电解质为脆性材料，机械强度低，使其容易在电池的制造及运行过程中由于热应力及机械应力而破裂；其三，CeO_2基电解质在燃料极一侧由于Ce4+还原为Ce3+出现电子导电，降低电池的输出电压和输出功率，影响电池的性能。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

矿石中天然固有的杂质严重影响其后来的质量。矿石的形成是地质变迁的结果，包括地壳运动，火山爆发，沉积作用，冰河作用和风化等等，在这些作用下，生成了火成岩，火山杂岩，水成岩和沉积岩等，一些矿石是由于这些作用共同形成的，这就是自然界中没有纯净矿石的原因。由于这些原因的存在，需要用分离技术和器械，也就是矿石加工设备对矿石进行的分割，迄今为止这些矿石加工设备已经不能够满足冶金工业的需要，科学家们力图用激光把冶金工业提高到一个新的水平。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
