位置正常

Sometimes the stability is stated in terms of the added rearward travel possible without instability.

有时，稳定性是用重心从正常的后部位置再向后移动，但仍然保持稳定状态的附加移动量来判断的。

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。

In addition,CT virtual endoscopy allows structural visualization of the paranasal sinuses and distal portion of obstruction with unconventional angles and locations not accessible with rhinoscopy.

Normal size, shape and position of the supra and infra-tentorial ventricular system.

在上和infra-tentorial 心室系统的正常大小、形状和位置。

Normal position, that is, belonging to the physiological, the talipes.

正常位置的，就是属于生理性的内、外翻足。

The airplain is falling ,please come back and sit down ,tie belt ,retrack your teapoy,and adjust your seat back on normal position

飞机正在下降，请您回原位坐好，系好安全带，收起小桌板，将座椅靠背调整到正常位置。

The flying height of this plan is declining now,please go back to seat,tie safty belt well,pick up the teapoy,turn the seat backrest in common position.

飞机正在下降，请您回原位坐好，系好安全带，收起小桌板，将座椅靠背调整到正常位置。

Resul ts:Besides the structural changes caused by operation,barium meal rev ealed:①decreased gastrointestinal tonicity and abnormal configuration.②hypokin esis and incoordination of stomach.③moderate gastric retention but with normal emptying of liquid.

结果：除手术引起的胃肠结构改变外，胃肠钡餐还显示：①胃肠张力降低、形态失常；②胃肠动力减弱，运动不协调；③中等量胃潴留，但液体排空正常；④胃肠位置呈中线性变化但无出口狭窄梗阻。

TO USE TREMOLO: Rotate arm into playing position and use normally.

使用方法颤音：旋转位置和玩弄正常使用手臂。

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.
