Paper industry the past few years of hard work elites and radical reform of our paper has been the rapid development, but in the second half of 2008 the global financial crisis under the fierce attacks of the paper we are faced with unprecedented challenges, reduce a large number of foreign orders, hydro pulper aging equipment, paper machine operating speed of the slow, low value-added products, filter equipment, up-flow low pressure output screen, high power consumption, coupled with China's increasing pollution of the paper industry environmentally friendly water treatment sludge, objectively, there are difficulties we are now, how fast out of the current predicament?

经过这几年造纸行业精英们的艰苦努力及大刀阔斧的改革我们的造纸业有了飞速发展，但是在08年下半年全球金融危机猛烈的侵袭下我们的造纸业正面临着前所未有挑战，国外订单大量缩减，水力碎浆机设备的老化，纸机车速的运转缓慢，产品的附加值低，筛选设备升流压力筛的产量低，电耗高，加上我国加大对造纸行业污水污泥的环保治理，客观上我们现在是有困难，如何快速走出当前的困境？

Under intense pressure from donors Mr Kibaki removed two ministers accused of corruption, only to reappoint them a few months later.

By systemic researching and simulating experiment, the text gains such results as follows,1. On the base of sufficiency research on the oil-gas hydrocarbon systemic chemistry composing and the physical chemistry characters, we traverse the mechanism of the paraffin's deposition. Then we consider that paraffin deposition is a complex process ofphysical chemistry, which includes more than one single mechanism.2. Traversing and comparing the literature in detail on different factors that has effect on paraffin deposition, the available experimental methods on paraffin deposition, prevention of paraffin deposition, and removing of the deposited paraffin on the spot.3. Ameliorated the laser equipment of solid particle inspecting system and the corresponding test methods. Determine WCT of dead oil and live oil from KS101 well under different pressure with this system. The result implies that dead oil has opposite regulation on paraffin deposition temperature to live oil.4. A vapor-liquid-solid envelop is drawn by superposition regular vapor-liquid envelop and WCT curve thereby explained that the departure and quick raising of the curve in the low temperature zone is caused by the appearance of paraffin in solid phase.5. Estimation is made to determine the depth of paraffin deposition in the well.

通过系统的研究和实验模拟，本文取得了以下研究成果：(1)在充分调研油气烃类体系的化学组成及其物理化学特征的基础上，详细研究了石蜡沉降的机理，认为石蜡沉积是一个复杂的物理化学过程，是多种机理共同作用的结果；(2)深入调研并综合阐述了影响石蜡固相沉积的各种主要因素，对目前国内外常用的有机固相沉积实验研究方法和现场清防蜡措施也做出详尽的描述，并加以对比评价；(3)改进了油气藏开发重点实验室自行研制组装的高温高压下测定固相沉积的激光装置和测试方法，并用该套设备测定出柯深101井的井口脱气油样和凝析气平衡油样不同压力下的析蜡点，实验结果表明，脱气油和平衡油析蜡规律相反；(4)将常规气-液两相相图和析蜡曲线叠加得到了气—液—固三相相图，从而解释了气-液两相等液量线在低温区域偏离正常并快速上翘是由于体系有石蜡固相出现；(5)利用实验测试的析蜡温度预测析蜡位置，表明只有在距井口465m油管以上会有蜡析出。

I had a great repayment pressure this month reluctantly also, we do not know the next month.

我也有很大的还款压力，这个月的勉强还了，还不知道下个月该怎么办。

Here, the author thinks, be not to Yahoo with the collaboration of Microsoft with respect to imply loss or the market is short of break, on one hand Yahoo has been not former times comparing today, want to searching domain reseizure what great progress difficulty comparatives is big, have a strong opponent afore especially Gu Ge, hind the case that pursues arms Microsoft falls, return the awkward situation that will face client prediction of a person's luck in a given year, cooperate with Microsoft or will form " double win " situation, song of collective antagonism cereal; On the other hand, the glides to also give Yahoo high level administrator of company outstanding achievement brings not little pressure, among them this year first quarter, the net gain of Yahoo is 118 million dollar only, than last year the 537 million dollar of the corresponding period glides 78%, how to seek the new point of growth of company profit, also Yahoo CEO Ba Ci is needed to face, and if the collaboration with Microsoft can involve capital level, so Yahoo sells advertisement and search through exchanging relevant business will obtain more battalion to close with respect to may not it is a tickler.

在这里，笔者认为，与微软的合作对于雅虎来说并非就意味损失或者市场缺失，一方面雅虎已经今非昔比，想要在搜索领域再取得长足发展难度相当之大，特别是在前有强敌谷歌、后有追兵微软的情况下，还将面临着客户流失的窘境，与微软合作或将形成"双赢"局面，共同对抗谷歌；另一方面，公司业绩的下滑也给雅虎的高层管理人员带来不小压力，其中今年一季度，雅虎的净利润仅为1.18亿美元，比去年同期的5.37亿美元下滑78%，如何寻找公司利润的新增长点，也是雅虎CEO巴茨所需面对的，而与微软的合作如果可以涉及到资本层面，那么雅虎通过换取销售广告以及搜索相关业务来获得更多的营收就未必是件难事。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
