When oversubscription happens, underwriters can reduce the level of discount and increase the bottom price by strategic allocation so that both financing cost and IPO underpricing will be less. It suggests that financial supervisor should allow underwriter to allocate IPO stocks freely to a certain extent in China.3. If independent IPO allocation is allowed in IPO bookbuilding, the underwriter and affiliated institutional investor maybe exploit free allocation and information asymmetry to manipulate.

在发生超额认购时，承销商通过有策略地分配股票可以有效地降低折价水平并保证较高的发行底价，减少了发行成本的同时也减轻了IPO抑价程度，建议我国监管当局可以考虑在适当的时候赋予承销商一定的新股自主分配权。3、在有自主分配权的条件下也可能会发生承销商与关联机构投资者共同进行市场操纵的行为。

In Xinxiang Aera of Henan Province in 1997, the occurrence of cotton pests were investigated in the Bt cotton and common cotton fields The result showed that the numbers of cotton bollworm egg were similarly in both fields, but that of survival larvae on Bt cotton were lower than that on common cotton The occurrence of cotton aphis was no difference but the spider mite were more heavy in Bt cotton field At the same time,control strategy against cotton pests were discussed for the Bt cotton

对河南新乡棉区种植的转Bt基因棉和常规棉棉田虫情进行了定点系统调查和大田普查，结果表明：棉铃虫在两种棉田棉花上的落卵量无明显差别，而幼虫存量差异显著，Bt棉棉花上幼虫存量显著降低；Bt棉对棉蚜的发生无明显的影响，而Bt棉上棉红蜘蛛的发生比常规棉略重，同时初步研究制定出种植Bt棉后的棉虫综防对策

The results demonstrate that ACM-A is capable of intercalating between the base pairs of DNA double helix, the π-π electronic overlapping between π-electron of ACM-A and DNA stabilizes the ACM-DNA adduct, and through electrostatic interaction, the trisaccharide interacts with the minor groove of DNA owing to C(3') amino group.

实验结果表明，ACM-A主要以其蒽环平面嵌入DNA双螺旋碱基对之间，发生-等电子间相互共轭，同时药物糖基上C3'位的-N(CH3)2基团带正电荷，易与带负电荷的磷酸骨架产生静电吸引，从而发生沟槽作用，嵌入DNA的小沟区，这是二者之间的主要结合模式。并且，DNA与ACM-A药物原型的亲和力要强于还原后的药物代谢产物。

In addition, coseismic Coulomb stress changes also have great influence on aftershocks distribution.

同时，由于鲜水断裂带不同断裂间的相互作用，发生地震的断裂在其相邻的断裂上产生同震库仑应力增加，使下次地震发生于其相邻的断裂上，这也可能是鲜水河断裂带地震沿带南北迁移的重要物理机制。

Result 1. CDK4, P16 were expressed in parabasal layers and the upper layer, mainly in the prickle and granular layers of cholesteatoma epithelium. Their positive rates were 68.6% and 88.6% respectively. Statistical analysis showed that there was a significant difference in positive rates between

CDK4与P16在中耳胆脂瘤上皮中均过度表达且有一定程度的正相关性，表明它们在疾病发生中是共同而非单独起作用的，从细胞周期的角度可反映胆脂瘤上皮细胞过度增殖的同时也增强负调控因子来抑制增殖，使凋亡同时加快而达到新的平

Result: CDK4 and P16 were expressed in parabasal layers and the upper layer, mainly in the prickle and granular layers of cholesteatoma epithelium.

CDK4与P16在中耳胆脂瘤发生中是共同而非单独起作用的，从细胞周期的角度可反映胆脂瘤上皮细胞过度增殖的同时也增强负调控因子来抑制增殖，使凋亡同时加快而达到新的平衡。

Nevertheless, in these aPproaches the contact intethee are charactered sboly edstiffeess K. and K.' which is not PerfeCt and rigorous in thc vitw of solidmechanics and rather rough for the description of the behavior of the iDtfores. Incollbet, taken as a contact Problem, the principal chatrs of the iDtCthees can bereflected: the cbntact inifore is of shear strength Which imPlies tha a genericpair of contact points on the inidse will displace coincidentally if the tangentialfbrce at this POint has not reahed the 1imit resistance, else, relative s1ide betwee the\ points will occur along the tangental direction.

本论文在对这两种方法进行认真的分析后，说明它们对不连续面的描述并不合理，也无法反映出不连续面的主要力学特性，同时指出，将带有不连续面的岩土工程问题作为接触问题计算更为合理，它可将不连续面受力变形的主要特点反映出来，即：(1)接触面具有相应的&抗剪强度&，即当接触面上某一点处的切向应力小于该点处的抵抗强度时，点对共同变形；达到强度时，则沿切向发生相对滑动；(2)在整个变形过程中，发生接触的变形体不能相互侵入。

In an attempt to evaluate the safety and efficacy of Healon in trabeculectomy, 20 eyes with Healon and 20 eyes without Healon injection after trabeculectomy are compared. Trabeculectomy using Healon will not induce transient rise of intraocular pressure. By filling the anterior chamber with Healon, a tamponing effect results which will maintain a deep chamber and reduce complications such as flat anterior chamber, choroidal detachment and striate keratopathy in the early postoperative period. In long-term evaluation there is no difference in pressure control, conjunctival scarring and corneal endothelial cell loss between Healon group and Non-Healon group.关键词 trabeculectomy , flat anterior chamber , choroidal detachment , intraocular pressure

为了评估Healen在小梁切除术中之疗效及安全性，选20位接受小梁切除术者，同时注射Healon於前房为实验对象，另20位接受传统小梁切除术为对照组，发现使用Healon并不会引起一过性眼压上升的现象，Healon注入前房，产生填塞作用，最大的好处是可以维持前房深度，减少术后合并症如前房消失，脉络膜剥离及角膜水肿等，然长期追踪，对於降眼压的幅度，不因使用Healon而可达到低眼压状态，也不会减少结合膜瘢痕化而促进房水引流，然Healon系一无毒，无炎性，无抗原性高黏稠性的物质，不因使用而发生炎性反应，同时有保护角膜内层细胞的功能。

The author has made researches on the social occurrence of man's functions of symbols and finds out that the occurrence of babies' self-consciousness is achieved under the conditions babies have possessed dualistic attention-----that is to say, attention can concentrate on two signal sources at the same time or it has two focus of attention.

论文摘要本文作者对人的符号功能的社会系统发生进行了研究，发现婴儿自我意识的发生是在婴儿已经具有二元注意--即注意力能同时集中到两个信号源或者说有两个集中点--的条件下实现的，这种并行性注意使一种称为反身性条件反射建立成为可能，并形成了具有符号功能的神经机能组织--二联体。

In view of easy fusion flaw between connecting of doubler strake and deck plating or bottom plating strengthened, this paper puts forward a fire-new welding technics for the purpose to improve the technics of welding connecting of doubler strake. Under the help of this way, connecting of doubler strake can be penetratingly fillet welded, but not fuse with deck plating or bottom plating strengthened, at the same time the figure of weld surface can also be managed for increasing fatigue strength of connecting.

本文针对复板条对接接头容易和被加强的甲板或船底板发生粘连的缺点，从改善复板条对接接头的工艺入手，提出了新的焊接工艺，使得复板条对接接头既能保证完全焊透，又不会和被加强的甲板或船底板发生粘连，同时对焊缝表面形状进行处理，以提高接头的疲劳强度。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
