不适

Although the standard k-ε turbulence model has been proved to be a model adapting a large range of conditions, it does not fit in with the cases where the normal Reynold stress of fluid is of great importance. As generally known, these cases include at least some cases where recirculation or secondary flow takes place.

在目前多数研究中，采用的湍流模型为标准k-ε湍流模型，这种模型虽已被证实是一种适应范围较大的模型，但其并不适用于流体中雷诺正应力占重要作用的情况，目前所知，具有回流区和二次流的一些流动便属于此种情况。

The reconstruction problem is ill-posed, so two optimal criterions, the least module and the smoothness criterion base on Tikhonov regularization technique, are introduced into reconstruction algorithm. Many regularization parameters choice strategies are investigated, and the TPA(Two—Parameter Algorithm) strategy which is based on the Morozov discrepancy principles, is implemented in two regularization reconstruction algorithms.Numerical experiment results show that the nonnegative and smoothness constraint condition can overcome the difficulty of iteration semiconvergent, preconditioned technique can improve convergence rate and reconstruction accuracy, smoothness regularization criterion can meliorate ill-posed problem of reconstruction and enhance iteration stability, and the TPA is an effective strategy of regularization parameters choice.

数值试验表明：在共轭梯度法中引入非负约束和光滑约束改善了迭代的&半收敛&性，非负约束保证了解的非负性，光滑约束抑制了重建解的振荡现象，约束算法的重建精度与无约束算法相比大幅度提高；在约束共轭梯度重建算法中引入预优技术，可以加快算法的收敛速度，提高迭代的稳定性和重建精度；引入光滑准则的正则化技术可以有效改善图像重建问题的不适定性，加快迭代的收敛速度，提高迭代的稳定性和图像重建质量，计算正则参数的TPA算法在闪光照相图像重建中是有效的。

Because of the stratigraphic conditions of multi-lithologies and thin-bed association, unstability of lithofacies in the vertical and lateral direction, and the particalar conditions of seissmic geology in Inland Basins, Western China, a stratigraphic model of sedimentary facies in which there are many theoretical reflecting seismic interface does not completely display on the seismic section, especially the some the most important stratigraphic information such as toplap, onlap, progradation, erosional truncation and fill of channal, divergent, shingled, ect.

本文在研究了9类沉积相及相组合地层模型的地震模拟记录后证明：现今流行的在地震剖面上划分地震相进而应用国外海相地层反射模式再转换为沉积相这一所谓&相面&方法完全不适用于西部陆相盆地沉积相地层模型的特点，作者首次开辟了用速度参数，合成地震记录、二维地层模型技术研究西部盆地地下沉积相的新途经。

导读：目的探讨医院改制中护士工作不安全感与躯体化不适的关系。方法对348名健康护士采用躯体化评定工具和工作不安全感问卷进行问卷调查，对调查结果进行相关分

During the peroid of applying the tube, the urocystic stimulus syndrome and indisposition on renal region appeared in 21 cases, three cases were urinary system infection, there was no urinary fistula, obstruction of ureter and stoma stenostomia in all patients.

置管期间，出现膀胱刺激征及肾区不适21例，泌尿系感染3例。无尿漏及输尿管梗阻及吻合口狭窄发生。

Stiff neck is also called stiffneck, which is a functional disturbance of the neck muscle because of the uncomfortable pillow. If it is not cured in time, it will become a chronic disease, not just influencing the life quality, but also becoming cervical spondylosis.

落枕又叫失枕，大多指因睡觉枕头不适造成的颈背部肌肉功能障碍，如不及时治疗，转为慢性疾病，不仅影响生活质量，也会发展为颈椎病。

None cases suffered from serious complications such as pharyngeal secondary hemorrhage, infection, pharyngeal paraesthesia,velopharyngeal inadequacy,stomatolalia.

结果 术中仅轻微疼痛及吞咽不适，术后无明显并发症发生，包括出血、感染、组织糜烂，未出现腭咽闭合不全，无发音和吞咽障碍。

Subhealth human health and disease in the transition between the stages of physical, psychological diseases, but there are a number of subjective symptoms and psychological performance experience.

亚健康是人体处于健康和疾病之间的过渡阶段，在身体、心理上没有疾病，但主观上却有许多不适的症状表现和心理体验。

MATERIALS AND METHODS: From September 1997 to September 1999, 56 patients with either infertility (36) or scrotal discomfort (20) who underwent subinguinal microsurgical varicocelectomy were reviewed. All patients were confirmed as having varicocele by pre-operative color flow mapping.

材料与方法：从1997年9月到1999年9月，回顾了五十六个或者不孕（36）或者阴囊不适（20）的患者，接受鼠蹊管下方的显微精索静脉切除手术，所有病人都采用术前彩色血流杜卜勒超音波确定诊断为精索静脉曲张；此外，以Wilcoxon等级测验统计应用於精虫变化的比较。

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。
