Therefore, a secondary infiltration or metastasis to the colon and rectum must be excluded before a definite diagnosis of primary colorectal signet ring cell carcinoma can be established.

因此，在原发性结直肠印戒细胞癌明确诊断前必须排除其它器官的直接浸润或转移至结直肠。

Methods: During the April 2003 to December 2004, from the patients with different position colorectal cancer beyond Dukes C stage who were performed laparoscopic radical operation random draw 20 patients as experiment group, and from patients with different position colorectal cancer beyond Dukes C patients who were performed open radical operation 20 patients took randomly as contrast group. We draw thepatients blood about 5 ml from antecubital vein at the time before and after the operation about 30 minutes respectively, preserved the blood in deep hypothermia circumstance,cytrokeratin-20(CK-20) as the micrometastasis maker, using the RT-PCR technique,G3PDH as the intra-contrast gene, quantitatively detect the amounts of CK-20 in the blood with the gelatum imagery system and the computer analyzing software on the gelatum imagery system ,in order to compare the influence of the laparoscopic and the open operation on the micrometastasis.

Results One case with transverse mesocolon pore hernia, one with obturator hernia and one with paracecal hernia were confirmed by exploratory laparotomy. There were six cases whose hernias resulted from the fall of export jejuna into import jejuna after Billroth II anastomoses in front of colons, five from the pelvic bottoms' peritoneal fissure and four from the fissure appearing between descending colon and lateral abdominal wall after Miles' operation, one from greater omental adhesion to sigmoidal wall after sigmoidostomy, and one from inflammatory adhesion on the basis of Meckel's diverticulum. The other 17 cases' hernias (48.7%) were caused by the fissure among celiac adhesive bands, peritonea, celiac organs, enteric walls and intestines.

In this paper, the stress and strain fields of lithosphere in Himalayan Western Syntaxis orogenic belt and its adjacent areas since 10Ma are investigated through using the 3-D finite-element simulation, and deformation and evolution process in former 2Ma are simulated with different rheological parameters and rheological structure. Studies on functions in simulation process of different viscosity parameters, constitutive relation and changes of initial curst thickness show below results:(1) When various viscoelastic models are adopted, the selection of the coefficient of viscosity in the Western Syntaxis area has important influence on the its uplifts and evolutions. The computational results show that the viscosity in the Western Syntaxis area should be smaller than 1023Pa·s;(2) When the elastic model is adopted in relatively rigid Tarim basin, obvious changes are induced to the stress and strain fields of the whole Western Syntaxis area;(3) The existence of mechanical property stable block doesn′t make the propagation of the stress field show obvious decoupling phenomenon.

用数值模拟的方法探讨了自10 Ma以来喜马拉雅弧形造山带的西构造结及邻区岩石圈的形变和位移变化特征，并采用不同的流变参数和流变结构模拟了前2 Ma内的形变和应力场的演化过程，通过对不同黏性系数、本构关系和初始地壳厚度的改变在演化过程中所起的作用研究表明：（1）采用黏弹性模型时，西构造结区黏性参数的选取对西构造结及邻区隆升高度和隆升范围有重要影响，计算结果给出西构造结区地壳黏性系数应小于1023Pa·s；（2）相对刚性的塔里木盆地采用弹性结构时，对整个西构造结区域的应力和应变场均能引致明显变化；（3）力学性质稳定块体的存在并没有使应力场的传播出现明显的解耦现象。

Coffer dams and back berms are often built in the two sides of a roadbed for convenient construction, resulting in obstructing wave but letting tide come into the top of the silt roadbed .

海滩区淤泥长期受周期性的波浪荷载和潮汐荷载作用，在淤泥路基排水固结处理前，为便于施工，一般在两侧填筑围堰，并修建反压护道，波浪作用被阻隔，而潮汐通过排水层进入淤泥路基顶面，对淤泥路基的排水固结过程产生重要影响。

At the same time, the finite staff element method is used to analyze the influence of beam rigidity; and the two new methods proposed are used to analyze the influence of connect way between piles and beam; and the conclusion is obtained that the rigidity ratio between beam and piles being 0.48 is appropriate; the continuative increase of the rigidity ratio is not significant; the worst condition is that connecting way between piles and beam is hinged; the best condition is that connecting way between piles and beam is rigid. Whether is single-row pile or are double-row piles, when the front of single-row pile or the front of the front-row pile(in the double-row piles) needed excavation, it is supposed to that ought to be carefulness to excavate, because it is that the engineering cost increased greatly.

同时，用有限杆单元法，对双排桩的连梁刚度和用文中提出的方法以桩梁连接方式进行了试验和理论分析得出如下结论：在满足不相互影响排桩间距的情况下，桩顶连梁与桩的刚度比不小于0.48是合适的，此时再增加连梁刚度无意义；桩梁连接为铰结时双排桩受力变形性质最差，刚结时受力变形性质最好；不论是单排桩还是双排桩，桩前和前排桩桩前土体需要开挖时应慎重，因为这种开挖对支护结构影响很大，造价增加很多；双排桩省钱，而且抵抗变形的能力强，值得在工程中研究和广泛应用

Hole , and use a stuff to seal the middle hole before the electrophoresis; after product electrophoresis, takes down the stuff and enters the drying oven to roast, when roasting in the hole causes the paint the residual liquid flow to cake in the two ends of the surface.

Seaside silt is always under periodical effect of wave and tide.
