为了节省施工成本、加快施工进度，目前在水利工程施工生产中逐步试验并推广的保护层开挖方法有水平预裂法，柔性垫层法等。

Leaf venation usually longitudinal, sometimes pinnate and inflorescences then brushlike; floral units sessile, variously arranged in spikes or clusters.

叶脉通常纵裂，有时羽状和花序然后刷子状；花单位无梗，各式地排列在穗状花序或簇生族。 2 Melaleuca 白千层属

Structural features of west slope region is simply by the study of structural and evolution characteritics inwest slope region, it is eastern slope unicline, structural plane map of each reflection interface express thatslope gradual decrease one by one from bottom to top. Structural evolution can be divided into three stagesof chiasmic, depressed and abortion equilibrium.

通过西斜坡区构造及其演化特征研究，得到西斜坡区构造面貌简单，总体为东倾的单斜，各反射层构造平面图反映出斜坡的坡度自下而上具有逐渐减小的趋势；构造演化可以分为裂陷阶段、沉陷阶段和萎缩平衡3个阶段。

Proteins associated with the membrane and the cytosolic portions of the proteome under different copper ion concentrations were differentially labeled with an acid cleavable isotope-coded affinity tag reagent, and the labeled peptides were separated by two-dimensional chromatography and characterized by electrospray ionization-tandem mass spectrometry.

我们分别将在不同铜离子浓度下的细胞质以及细胞内膜中所有蛋白质标识上酸裂性同位素亲和性标识(acid cleavable isotope-coded affinity tag， cICAT)试剂，用二次元管柱层析将所有标识并酵素水解过的片段分离，并且用电洒式串连质谱(electrospray ionization-tandem mass spectrometry， ESI-MS/MS)以及基因体定序资料库决定蛋白质序列。

Yet in many vertebrate groups, teeth are not restricted only to the oral cavity, but extend posteriorly as pharyngeal teeth that could be derived either directly from the endodermal epithelium, or from the ectodermal epithelium that reached this location through the mouth or through the pharyngeal slits.

但在很多脊椎动物里牙齿的发育不仅只有上述来源，还有向后延伸形成的咽部牙齿，可能由内胚层上皮或经由口腔或口咽裂至此部位的外胚层上皮形成。

Pearl River Mouth Basin, an epicontinental sea and marginal sea basin, is one of depositional basins abundant in oil and gas in China.

该沉积组合反映了张性边缘海盆地的演化特点，盆地演化与资源效应表现在裂陷期、热沉降期及断块升降期的生储盖配置，故勘探目的层段为热沉降阶段所形成的三角洲碎屑岩与陆棚碳酸盐岩。

Methods: Two hundred and forty-seven patients with head and neck lesions were operated on from 1983 to 2001. The surgical procedure was decided on the pathologic conditions. The surgical defects were repaired by pectoralis major myocutanous flap or combined with delto-ectopectoralis flap, split skin flap, laryngotracheal flap, tongue flap, stomach flap, sternohyoid myofascial flap, sternocleidomastoid myoperiosteal flap, epiglottis flap.

1983至2001年手术治疗了247例头颈部肿瘤患者，用胸大肌肌皮瓣或联合其他组织瓣如胸三角皮瓣、裂层皮片、喉气管瓣、舌根瓣、胃瓣、胸骨舌骨肌筋膜瓣、胸锁乳突肌骨膜瓣、会厌瓣等对术中组织缺损进行了整复。

They are inverted to determine parameters such as locations of microseismic sources. The resulted parameters are then used to guide the production activities.

在油气开发领域，该方法主要用于油田低渗透储层压裂的裂缝动态成像和油田开发过程的动态监测，主要是流体驱动监测。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
