Two kinds of cross-linked polyacrylate latices with relatively narrow distribution of particle diameters, which are abbreviated to P and P/P, were synthesized by seeded emulsion co-polymerization, respectively. Butyl acrylate and 2-ethylhexy! acrylate were used as comonomers of ACR core, styrene and methyl methacrylate were employed as comonomers of ACR shell, and 1,4-butanediol diacrylate was used as cross-linking agent.

采用丙烯酸丁酯和丙烯酸2-乙基己酯(2-EHA)为核层单体、苯乙烯和甲基丙烯酸甲酯为壳层单体、1，4-丁二醇二丙烯酸酯为交联剂，通过多步种子乳液聚合方法合成了P、P／P两种具有窄粒径分布的共聚丙烯酸酯胶乳。

Inflorescence spikelike, cylindrical, composed of spiny or bristly deciduous burrs arranged along an angular, often sinuous rachis; burrs sessile or with an obconical basal stipe, each composed of 1 or more sessile spikelets surrounded by an involucre of spines and bristles; bristles flexuous or more often spinous,± flattened, grooved on the outer face, united below, the degree of union varying from a small basal disk to a deep cupule, inner spines or bristles often ciliate around spikelets. Spikelets lanceolate, acute; glumes unequal, shorter than spikelet, lower sometimes suppressed; lower floret membranous, staminate or neuter; upper floret firmer, protogynous.

花序穗状，圆筒状，由落叶的毛刺沿着一具角安排的具刺的或具刚毛，通常波状的轴组成；毛刺无梗或具基部的倒锥状柄，每一个由1无梗或更多组成以总苞的刺和刚毛包围；或更多的刚毛曲折通常spinous，多少扁平，在外面上具凹槽，下面的合生，协会的度从一小的基部的花盘变化到一深的壳斗，小穗披针形，锐尖；不等长的颖片，短于小穗，降低有时压抑；更低的小花膜质，雄蕊花的或中性；坚定的上面小花，雌蕊先熟。

Every family was resolved monophyletic except Tellinidae and Solecurtidae. The paraphyletic Tellinidae and polyphyletic Solecurtidae mixed together, indicating the close relationship between two families.

双壳纲各科都构成了单系群，樱蛤科和截蛏科除外，前者并系发生，后者则多系发生，二者可能具有较近的亲缘关系。

The chitosan-based microsphere delivery system enhanced the humoral immune response induced by polytope DNA vaccine.

壳聚糖微球疫苗投递系统可提高多表位DNA疫苗的免疫应答效果。

In the basal ganglia, internal and external capsule, corona radiata, centrum semiovale, periventrical, the incidence rates of HSIs in hypertensive patients aged from 60-69 were greater than that of the group with normal blood pressure P""

高血压患者多在60～69岁时表现明显脑损害；慢性高血压大鼠直到鼠龄较大时，尾壳核区域出现明显的病理改变，才在MRI上显示出来。

Lobes of leaf blade 9-14 cm, apex long acuminate; calyx subcampanulate, ca.

小叶9-15；壳平滑成脊状深具洼点的具和洼地和2突出脊或更多 6 F。

The knowledge obtained here as well as the new morphologies identified provide useful information for future rational design and synthesis of novel multicompartment micelles.5. A superstrong segregation regime theory model for core-corona micelles and core-shell-corona micelles is developed.

这些信息对将来合理设计和合成新型多隔段胶束提供了指导。5、建立了用于描述核-冠胶束和核-壳-冠状胶束的超强分凝形式理论模型。

In order to study the effect of chitosan coating on keeping fresh to Typha latifolia L., the sensory quality of T. latifolia L. as well as its rate of weight loss, decay index, Vitamin C content, fibrin content and polyphenol oxidase activity, were determined after treated with chitosan coating.

在蒲菜贮藏过程中，通过评价其外观品质及测定其失重率、腐烂指数、维生素C含量、纤维素含量和多酚氧化酶活性等指标，研究壳聚糖涂膜对蒲菜采后生理和品质的影响。

We feel that this complicates paper case-making much better strength, quality is also better.

我们觉得这比单纯的纸面书壳强度好得多，质量也好些。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
