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.

无论是人车分流还是人车共存，都不应该是针对整体而言的，它们的出现应该具体到不同的时间段，不同的空间领域，不同使用人群，所以应该把有限的道路空间资源分配到能够发挥他们最大优点的地方去。

However, the solutions of the Cauchy problem of the nonlinear hyperbolic system generally develop singularities in finite time even if the initial data are small and smooth.For this reason, solutions must be found in the space of discontinuous functions. Therefore, one can not directly use the classical analytic techniques that predominate in the theory of partial differential equations of other types. Instead, we construct approximate solutions via the singular perturbation methods. By using the compactness of the approximate solutions, we can obtain the existence of the solutions of original system.

然而一般而言，即使是在初值很小且光滑的情况下，非线性双曲型守恒律的Cauchy问题的解在有限时间内也会出现奇异性，为此，我们必须在不连续函数空间中寻找上述问题的解，因此对这类问题的研究，我们也不可能直接利用在其它类型的偏微分方程中占主导地位的解析方法来解决问题，而是通过奇异扰动法构造近似解，由近似解的紧性得到原问题解的存在性。

Great majority Special Farmers" Cooperation set up by relying on the ability person , group leader business enterprise, or farming technology section, forming the property structure with differences, Hebei province is also the same, with the performance of the higher store capitalization concentration degree, appearing the difference between the big shareholder society member and small shareholder society member, the core society member and non-nuclear heart society member, the investor society member and manufacturer"s society member. the existence of advantage stock is the actual controller in co-operative societies, the surplus of the co-operative societies incline toward advantage shareholder, the Share Capital dividends is comparison far from the sum return according to trade return, Ministry of Finance funds nation the public finance prop up a funds and bring of the income is also basic for the big shareholder of the school store income.

合作社产权结构的同质性是合作社实现成员民主管理、资本报酬有限、盈余按惠顾额返还的基础，而河北省农村现阶段经济社会条件是资本和具有企业家素质的人才相对于劳动是稀缺的生产要素，绝大多数农民专业合作社都是依托能人大户、龙头企业、或农技部门组建，形成了农民专业合作社异质性的产权结构，表现为合作社股金集中度普遍较高，社员中出现大股东社员和小股东社员，核心社员和非核心社员，投资者社员和生产者社员的差别，合作社中的优势股为农民专业合作社的实际控制者，农民专业合作社的利益分配自然倾向于优势股东，按股分红的比例远高于按交易额返还的比例，国家财政扶植资金及带来的收益也基本为合作社的大股东所得。

Recently, Professor Liu Wen and his associates study the strong law of large numbers for Markov chain fields on trees. But for the nonhomogeneous Markov chain fields ,they only study the even-odd Markov chain and non-symmetric Markov chain. However, this article goes in the normal nonhono-geneous Markov chain fields and gets a class of limit theorems for the functions of two variables of finite nonhomogeneous Markov chain fields. Some limit theorems on the frequences of states and ordered state couples are obtained by several corollaries.

Virtually wiped out in the wild due to constant hunting (they were thought to be a threat to sheep and other small farm animals) and the encroachment of humans on their already limited habitat the Thylacine was finally recognized as being in danger of becoming extinct in 1936, too little, too late as that same year the last Thylacine, named Benjamin, died on 7 September as the result of neglect — locked out of its sheltered sleeping quarters and exposed to freezing temperatures at night in Hobart Zoo, Tasmania. 60 years on there are still claims of sightings but all are yet to be confirmed.

由于不断的狩猎（人们认为它们对羊群和其他小农场动物是一种威胁）以及人类侵占了它们本已十分有限的栖息地，袋狼的数量实际已经跌减，最终于1936年被认定为濒危灭绝物种，可是太晚了，袋狼的数量已经极少，也就在那年的9月7日，最后一只袋狼本杰明不幸死在了人类的疏忽之下---塔斯马尼亚的霍巴特动物园将其锁在了卧榻之外，导致本杰明在冰冷的寒夜里挨了整整一宿的冻。60年之后，虽然仍有人声称看到过袋狼出现，但是都没有得到确认。

The result indicated that, although microorganism from paddy soil could directly reduce Cr, the reduecing rate and efficiency were limited; the higher Cr concentration was, the less reducing ability the microbial showed; the microbe from different paddy soils had different effects on Cr reducing abilities; The reducing ability of the microbe from Sichuan paddy soil was higher than that from Jiangxi paddy soil. Cr added could be rapidly reduced in paddy soil under anaerobic incubation, moreover, the process of dissimilatory iron reduction of soil could obviously promote the Cr reduction. The existent of Cr could delay the appearance of Fe; the higher Cr concentration was, the later Fe appeared. The delayed time of Fe appearance was in accordance with the ending time of Cr reduction.

结果表明，由水稻土中提取的微生物虽然能够直接还原Cr，但其还原速率和还原程度有限，且Cr浓度越高，微生物的还原能力越差；不同来源的上壤微生物对Cr的还原能力有所差异，其中四川水稻土中微生物对Cr的还原能力均大于江西水稻土；在厌氧培养的水稻土中，添加的Cr可以较迅速地还原，其中土壤氧化铁的微生物还原过程对Cr还原具有明显的促进作用；Cr的存在导致Fe生成的时间出现滞后，目Cr浓度越大生成Fe的滞后时间越长；Fe产生滞后的时间与Cr还原结束的时间具有一致性。

The effect factors analysis based on FEM shows that: Raising the strength of concrete and the thickness of cover concrete would delay the cracking of concrete; Stress superposition would appear due to the influence of adjacent rebar, and increasing the rebar space would postpone the time of cover cracking; Stirrup could suppress the cracking of cover concrete, however, the effect is limited and the corrosion-degree-ratio and corrosion expansive force would not increase until the cover concrete cracking happens completely.

结合有限元分析结果，对影响锈胀开裂的各因素进行了分析，结果表明：提高混凝土强度、增加保护层厚度有助于延缓保护层的开裂；相邻钢筋的存在会使钢筋之间的混凝土出现应力叠加现象，箍筋对混凝土保护层内由锈胀产生的应力具有抑制作用，但是在保护层完全开裂之前，箍筋的抑制作用有限。
