不能解决问题的

However, because of the manual operation mode, which makes dataread and record randomly and trustlessly, and the diverseness of the detector'scapabilities, the current detecting ways for the train tail devices can't confirm theusing devices well worked. Making sure the reliability of the train tail devices andimproving the working safety have been an urgent problem to be resolved.

但现有的列尾装置检测，均由人工手动完成，读数、记录、随意性强，可靠性低，更由于现场检测人员业务素质参差不齐，责任心有高有低，不能保证投入运行的列尾装置均能正常使用，因此，如何确保列尾装置的可靠性，提高行车安全，已成为急迫需要解决的一个问题。

The main problems that the patient suffered from are: 1. The dejecta is leaked to vagina for unknown reason; 2. The break happened in the suture the fifth day after the 3rd duodenostomy surgery, and therefore, the dejecta is out from here instead of the ostomy tube made in the 2nd surgery; 3. A 15-centimeter-long wound by the surgery does not heal for a long time. All these problems could not be solved for a long time. For these reasons, the patient has already suffered from these and stayed in bed for nearly 3 months.

病人现在的主要问题是：一是阴道内出大便，二是第三次手术小肠缝合处在第五天接口崩开，现所有大便从小肠漏口排出，而原直肠造漏口不再有大便排出，三是腹部长约15公分手术刀口一直开敞而不愈合，国内的医生对病人的病情没有解决办法，致使病人已经卧床将近3个月不能下床，每天遭受着病痛的折磨，过着地狱般的生活。

However, because its feasible region is neither convex nor connected, this problem is intractable. Therefore, the nonlinear programming theory cannot be applied here directly.

然而该问题又是难解的，原因在于它的可行域既不是凸的又不是连通的，所以不能直接用现有的非线性规划理论来解决。

It assuages t he pa he sense of moral panic that has been the handmaiden of prohibition for a century.

但是这不过是政治家之间的一种不负责的承诺，并且不能从实质上所解决问题。

Environmental Improvement is the important element in Western China's Development policies It's an impend task to institute effective environment policies The usual environment policies are only to directly resolve the environment problems,which can't eliminate the fundamental origins In order to achieve the aim of administering both its root cause and symptoms,it's necessary for the direct environment policies to be implemented matched with indirect ones It also should pay more attention to reducing th...

环境治理是我国西部大开发战略的重要组成部分，因此制定切实有效的环境政策是当前的迫切任务。通常所说的"环境政策"仅指直接解决环境问题的政策，但若环境问题背后的本质原因不消除，直接环境政策仅能"治标"，无法兼顾经济发展、社会公平等目标，因此需要与间接环境政策配合使用，从而达到"标本兼治"的目的，同时在政策的执行中要注意最大限度地减少对经济行为的干忧，以保证经济、生态的协调发展。

The problem of multi-objective usually meet many conflict each other and can not use the objective of the same standard unit, then to employ membership function of fuzzy theory,at first each objective function to change fuzzy set and express with membership function, membership function include the maximum constraint, minimum constraint, the decrease function of monotonic property, to become optimal of the multi-objective function, but still to scanty of weighting value with regard to adjustment of objective function, thus this thesis proposes the method of combine orthogonal arrays and particle swarm optimization to solve the problem of multi-objective optimal power flow, each objective function separately add weighting value, to setting each weighting value of objective function in order to the result of anticipating.

多目标最佳化的问题通常会面临到许多互相冲突且不能用同ㄧ标准单位的目标，於是利用模糊理论中的归属函数，首先将各目标函数转换成模糊集合并以归属函数表示，归属函数包含了最大限制值、最小限制值、单调的递减函数所组成，将各目标函数利用归属函数表示，形成单一目标函数的最佳化，但是仍缺乏权重值对於目标函数的调整，於是本篇论文提出ㄧ种权重值设定与粒子群优演算法的方法去解决多目标最佳电力潮流的问题，将各目标函上分别加上权重值设定各目标函数的权重值，得到预期的效果。

He had the feeling I had had years before of being able to go through the motions, writing formulas and doing problems, but without any idea of what they were all about, seeing them only as a kind of mumbo-jumbo, meaningless recipes for getting meaningless answers to meaningless questions.

他跟我多年前的感觉完全相同，觉得自己能够跟上进度，能写公式，也能解题，可对于这些到底是什么，却摸不着头脑，只能当天书，当做是解决毫无意义的问题的毫无意义的答案的毫无意义的秘诀，仅此而已。

In the present paper, two new hypotheses are proposed that the outward normal of the dendrite surface is parallel to the gradient of the actual supercooling, and that the dendrite growth is capable to minimize the solute transfer .

但是，以往的研究中，枝晶组织和枝晶生长这两个密切相关的问题一直被分隔开来进行研究；在稳态枝晶生长理论研究中，由于枝晶界面真实形状问题没能解决，迄今为止，比较有希望的理论模型都是建立在"枝晶界面的旋转抛物面假设"这样一个早已被认定不是枝晶界面真实形状的"基础"上。

The multicast routing problem that finding the minimum cost multicast routing tree with many QoS constraints may be formalized to Steiner tree problem in network, which is a NP-complete problem that an algorithm that finds a Steiner tree can not get the best solution in polynomial time.

寻找有多个QoS约束的最小代价组播路由树可以形式化为网络中的Steiner树问题，它是一个NP完全问题，在多项式时间内不能得到最优解，因此研究者所寻求的是一种次优的、在最差情况和平均情况下的性能都接近于最优的解决方案。

My principal point is this: as a society, we no longer live under the illusion that the government can solve all our problems, that corporations will be fair, or that decency will prevail over profit.

我的基本观点是：作为社会中的一员，我们不应该生活在政府能解决一切问题；公司将是公平的；或正派能战胜利益的幻想中。

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%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
