Chapter 2 centres around the spiritual contents of her works. It penetrates through the skin to their core, that is, the tragic sense. Her works take the most ordinary people as characters. Unexpectable elements befall on these people, change their fate considerably. The helplessness of being fooled by destiny overshadows most of her works, leaving readers sign in vain. Then, her portrayal of characters bears a tinge of rootlessness, unsteadiness loneliness, filling the works with deep pensive mood. And finally, she exposes the ugliness of man from this covering of brilliance. Man dares not face his true being. What he shows and sees of himself tends to be his bright side. But his ugly side steels out, which gives himself a deadly blow.

第二章围绕作品的精神内蕴展开论述，侧重于由表及里的层层挖掘，悲剧意识构成王安忆作品精神内蕴的核心，其作品多写芸芸众生，在展现这些人的人生际遇时，难以预料的偶然因素总是改变着他们的命运，宿命感使作品笼罩在虚无的阴影之中，令人怅然；其次作家在写人物时，那种无根的漂泊感、孤独感，使作品有着深深的悲凉意蕴；再次就是对隐藏在绚烂表象之下的人的丑陋本质的发现，人总是无法面对自己真实的存在，看到的或表现出的总是冠冕堂皇的一面，但是那丑陋的一面总会在不经意中呈现出来，给人以毁灭的打击。

Methods One hundred and twenty teeth （140 canals） scheduled to be endodontically treated were randomly selected, 78 canals with apicitis.

In situ micro-suction cups were used to collect samples of soil solution with Arundo donax Linn and typha latifolia from defined segments at rhizosphere in field.The experiment was conducted to elucidate the contribution of iron plaque while wetland plants were used to remove phosphorus.

在田间条件下，运用土壤溶液原位抽提和毛细管电泳分析等技术，比较了芦竹和香蒲根表铁氧化物胶膜数量、土壤根际溶液磷质量浓度、根际土和根际溶液pH及根膜比等的差异，阐明了湿地植物根表铁氧化物胶膜对磷素从非根际土壤-根际土壤-根际溶液-根表铁氧化物胶膜-根系的迁移过程的影响以及在磷素净化中的根际调控机制。

Radiograph of teeth in mesiodistal direction were taken.

随机选择需行根管治疗术的单根管恒前牙、双尖牙 2 30颗，分为A、B两组，A组采用RootZX 根管测量仪测量根管长度，根管预备后，根管充填时加试尖步骤，调试出最适主尖后侧压充填根管，摄牙片

Root border cells are recently defined alive population sloughed from root tips and loosely adhered in the water soluble mucilage, and the root tip is just the target of Al toxicity, thus it was guessed that border cells might function crucially in the response to Al toxicity.

根边缘细胞是从根尖脱落下来并聚集在根尖周围的一群特殊的细胞，在根际周围起着至关重要的作用，国内外研究表明铝毒对植物影响最快的部位是根尖，而根边缘细胞在根尖产生并聚集根尖周围，因此推测根边缘细胞在根对铝毒响应中起重要作用。

The paper further analyzes and explores the ontological origins of "The world becomes an image" and "Man turns intoasubject", which is of determining meaning to the basic process of modern history, and points out, it is the western two-value logical nature and the abstract subjective principle of "objective thinking", while grasping "the being" as an entitative "object", that cancels the actual historical nature, excludes and overshadows the whole sensible richness of man and man"s sensible existent area which can not be objectified so that the freedom to use reason turns into rigidified rational external coercive power, resulting in the loss of meaning world as "the root of human life.

论文进而分析探讨了对于现代历史的基本进程具有决定性意义的&世界成为图像&和&人成为主体&的存在论根源，从而试图指出：正是西方&对象性思维&的二值逻辑本性和抽象主体性原则，在其将&存在&把握成实体性的&对象&时，也就取消了本真的历史性，排除和遮蔽了不能被对象化的人类感性的全部丰富性和人的感性存在领域；致使运用理性的自由转变成僵化之理性的外部强权统治，进而导致作为人类生命之&根&的意义世界的失落。

Comparison of different types of stem cutting in rooting induced and analysis the cDNA clones which may be associated with the occurrence of adventitious roots of P.euphratica,the model of ARF were initial establishment of exogenous IBA controlling endogenous IAA occurred threshold and equilibrium,that is,exogenous IBA receiving by receptor of stem cutting,and transfer into the cells,then turn into active IAA by the effects of the POD enzyme.

通过对胡杨3个不定根发生调控培养体系的比较和与胡杨不定根发生可能相关的差异基因的克隆分析，初步建立IBA调控胡杨不定根发生的内源IAA阈值和激素间平衡的模型，即外源IBA通过插穗受体接收，转入细胞内并在POD酶作用下转化成具有活性的IAA，当IAA的水甲在促根的阈值内并保持相对平稳时，则有利于生根；当IAA的浓度增高超过阈值且不稳定时，则抑制不定根的发生。

The fury and cruelty of this battle is quite revealed in the figure's complexion and body, or we say that to create these faces and bodies, Yin retrospected the genealogy from Goya to Francis Bacon, including many expressionists, such as Van Gogh, Munck, Oskar Kokoschka. All these artists painted 'anxious people', their brush touches looked intense and sensitive, their paints gave a horrible sense of solidity. The faces and bodies they painted are distorted and twitched under the burden of mental nightmare, so the organs are deformed, or even blurred; in 'Myth', the mental nightmare is incarnated as a stone, a battle between man and stones. Therefore, the deformed and distorted bodies look more vivid, when man strives to raise up a stone, all his muscles and expression are in an intense condition.

这种搏斗的激烈与残酷也充分表露画中人的表情和肌体之中，不妨说，在对这些面孔和身躯的塑造中，尹朝阳回顾了一个从戈雅到弗朗西斯·培根的谱系，其中应该包括了众多的表现主义者们，例如凡高、蒙克、奥斯卡·科柯施卡，所有这些画家都绘制了&焦虑的人&，他们的笔触显得激烈而敏感，颜料有一种可怕的实体感，他们所绘制的人物面孔和身躯，都具有精神梦魇的重负之下引发出的扭曲和抽搐感，器官因此而变形，甚至模糊不清；在《神话》之中，精神梦魇具化成了石头，具化成了人与石头之间的搏斗，人体的扭曲和变形的理由因此来得更为具体，当人奋力地举起一块石头时，他全身的肌肉和表情都自然地处在极度紧张的状态之中。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
