Although Opec might be tempted to increase production,Currie says the oil price is more of a refinery problem than a production problem.

尽管欧佩克也许会受到高油价诱惑而增产，科里表示，油价更多的是一个炼油问题而不是生产问题。

The air vessel works through twice air releases, solving the problem of inconstant air supply in process of cotton opening and blending. Test and application proves that the multifunctional air vessel can solve the problem of block up caused by the uniaxial cotton opener, keeping smooth operation of the production including effective dust removal, clog and iron seperation, avoiding the disadvantage of the former units including the sporadic cutover, simplifying the blow card flow, thus reinforce quality of the card sliver and the resultant yarn.

该设备通过两次释压，解决从抓棉到开棉、混棉间的气流不平衡问题，通过试验和实际使用，指出多功能气流塔能有效解决单轴流的堵车，保证清梳联的稳定运行；在除尘、重物分离和去铁杂等方面也有着较为理想的效果；能解决原各辅机在输棉管路中分散接入的缺点，简化了清梳联流程；能提高生条、成纱的质量。

The two-dimensional cutting stock problem is an urgent problem in practice, which is very difficult in computation theory.

矩形件优化排样是一个在计算理论上非常困难，在实际上有广泛应用的亟待解决的课题。

The paper uses it to construct optimal algorithms for two dimensional cutting stock problem and parallel-machine problem.

文中采用该模型构造了求解板材套料优化和并行多机调度问题的优化算法。

The nucleus of two dimensional cutting stock problem is to resolve a assembled optimal problem.

In brief, systematic analysis and research on the difficult form-finding problem and cutting pattern problem in tension structures design and construction are given in this thesis. Practical computation method and theory are presented.

综上，本文对张拉结构在设计和施工中的难题——形状确定问题和裁剪问题，进行了系统的分析研究，提出了实用的计算方法和理论。

Set packing problem is originated from the application of cutting problem which is to divide the elements un- der strong constraint condition.

But the problem that brand risk is consumer irritated feeling probably, still perhaps include consumer to know not to know this kind of problem that extends pattern, and look be like the moral risk that has nothing to do with company profit, in 3 get together after a series of incident that cyanogen amine causes, the viewpoint of value of the enterprise can lean gradually in the seating arrangement in sort probably before.

但品牌风险或许是消费者烦不烦感的问题，也许还包括消费者知不知道此种推广方式的问题，而看似与企业利润无关的道德风险，在三聚氰胺引发的一系列事件之后，企业的价值观或许会在排序中位次逐渐靠前。

The problem of finding stabilizer quantum-error-correcting codes can be transformed into the problem of finding classical self-orthogonal linear codes over the Galois field GF(4) under a Hermitian inner product. A classical cyclic code over the field GF(4) is self-orthogonal with respect to the Hermitian inner product iff the generator polynomial of its dual code is a factor of its generator polynomial.

寻找量子稳定子码的问题可以转化为寻找GF(4)上厄米内积自正交的经典线性码的问题；对于GF(4)上的经典循环码，它是厄米内积自正交的，当且仅当它的对偶码的生成多项式是其生成多项式的因子。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
