使确定

After verification of the program, the mathematical models of the suspension bridges were studied by means of the program, as well as the determination of the main cable's shapes and its internal forces at different stages, the calculation of the cable's unstrained length and the analysis of the construction processes, of which some new approaches were presented in the mean time. Thus makes the structural analysis results of suspension bridges more reliable and in accordance with reality.

在用算例验证了程序分析结果正确性的基础上，应用该程序对悬索桥的数学模型、各阶段缆索几何形状及内力状态的确定以及缆索无应力长度的计算和施工过程分析进行了研究，提出了确定缆索在成桥状态下的几何形状及其内力状态以及缆索无应力长度计算的新方法，使悬索桥的结构分析结果更加符合实际情况。

In chapter seven, the pricing regulation model of power transmission and distribution is studied. In this paper, the incentive mechanism models are designed under asymmetry information about product cost and market demand, which can induce the utility company to report true private type and control the over price successfully. The models can the incentive compatibility constraint and participation constraint required for participants and can maximize social welfare.

本章对管制者分别在企业成本和消费需求两种信息不完全的情况下，运用激励理论对需求确定和需求不确定两种状况设计对垄断输配电企业在满足参与约束和激励相容约束的激励机制真实披露真实成本的私人信息以使社会福利最大化的目的展开研究。

This is also a new idea wich is differ from former uncertain reasoning and more valuable for practical applications.

这也是本文不同于以往不确定推理的新构思，使不确定推理更具实际意义。

Butt Weld and docking and corner combinations Weld, in Weld ends located arc plate and extraction plate in igniting board then leads to the welding seam, joint halfway shall weld joints in front of 2.0 mm Department Firing arc, welding pieces after preheating rod will return to weld the origin, pool filled to the required thickness, before forward welding; Welding speed : Isokinetic welding requirements to ensure weld thickness, width uniform, which masks to look for hot metal and slag bath equidistance (2-3 mm)%; Arc welding rod length : different models and determined that the general requirements of arc length is stable, acid electrode generally 3-4 mm, 2-3 mm normally alkaline electrode%; Welding perspective : According to determine the thickness of two pieces of welding, welding angle has two aspects : First, the angle between the direction of the rod and welding of 60-75 ; The second is the angle between two electrodes and welding around, the same thickness as welding, welding and welding pieces incident angle of 45 ; When the thickness ranging from welding, welding electrode and thick and thin pieces of welding electrode side angle greater than the angle between the side pieces; Arc : admission to the end of each weld should be filled crater, in the direction opposite to the direction of the back-arc welding, arc welding unchanged inside pit in 1974, to prevent the crater bite of meat.

对接焊缝及对接和角接组合焊缝，在焊缝两端设引弧板和引出板，必须在引弧板上引出后再焊到焊缝区，中途接头则应在焊缝接头前方15～20㎜处打火引弧，将焊件预热后再将焊条退回到焊缝起始处，把熔池填满到要求的厚度后，方可向前施焊；焊接速度：要求等速焊接，保证焊缝厚度、宽度均匀一致，从面罩内看熔池中铁水与熔渣保持等距离（2～3㎜）为宜；焊接电弧长度：根据焊条型号不同而确定，一般要求电弧长度稳定不变，酸性焊条一般为3～4㎜，碱性焊条一般为2～3㎜为宜；焊接角度：根据两焊件的厚度确定，焊接角度有两个方面，一是焊条与焊接前进方向的夹角为60～75 ；二是焊条与焊接左右夹角有两种情况，当焊件厚度相等时，焊件与焊件夹角为45 ；当焊件厚度不等时，焊条与较厚焊件一侧夹角应大于焊条与薄焊件一侧夹角；收弧：每条焊缝焊到末尾，应将弧坑填满后，往焊接方向相反的方向带弧，使弧坑甩在焊道貌岸然里边，以防弧坑咬肉。

While no one is certain what causes these changes in the brain's nerve fibers,their effect is certain .

虽然没有人可以确定到底是什么使大脑的神经纤维发生了变化，它们的作用却很确定。

In the process of constructing the EDRI, we define the entropy weight on the basis of the theory of information entropy, and the synthetic weight of evaluating indicators, which is more rational for the model, is determined by combining the entropy weight with the expert's subjective weight.

在地震灾害风险指数的建立过程中，根据信息熵理论计算熵权，采用熵权与专家意见相结合的方法确定风险指数的综合权重，从而使模型权重的确定更加合理。

The provision in Food Safety Law that law-breakers are responsible only for food which don't reach fond safety criterion goes against consumers' protection and violaters' punishment. The compensation standard set in Fond Safety Law is so low that the functions of punitive damages cannot be on the full play. We should adopt comprehensive standard in consideration of concrete situations, in stead of fixed amount of ten times of fond price.

食品安全法》中规定以生产或销售不符合食品安全标准的食品作为适用惩罚性赔偿的前提不利于对消费者的保护和对违法者的惩罚；并且惩罚性赔偿标准偏低，并不能使惩罚性赔偿的多重功能得到完全释放，不应以食品价金来确定赔偿标准，应根据具体情况采取综合性标准来确定具体的赔偿数额。

Therefore, the true origin of any piece of wood packing material is difficult to determine and thus its phytosanitary status cannot be ascertained.

因此，所有木质包装材料的真实原产地难以确定，从而使其植物检疫状况也不能确定。

3Based the trait of the vegetable gum drilling and completion fluid, used LV-CMC,FJ-03, polyglycol, JL-α and SMP-Ⅰas the filtration control agents which should be optimized. Finally this paper optimized LV-CMC and polyglycol as the filtration control agents. In order to form a tough impermeable cake, this paper used QS-2 as the inflexible filling material according to the mechanism of fluid loss control.

根据植物胶钻井液完井液的特点，确定LV-CMC、FJ-03、聚乙二醇、JL-α、SMP-Ⅰ为降滤失剂的优选对象，通过实验优选出LV-CMC、聚乙二醇为植物胶钻井液完井液体系的降滤失剂，并根据钻井液的降滤失机理，为使形成更加坚韧致密的泥饼，确定QS-2作为刚性填充粒子。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
