结果 30例腭裂术后28例伤口愈合良好，无出现糜烂，2例于软硬腭交界处口腔粘膜侧有糜烂，但肌层及鼻腔侧粘膜层无裂开，未出现穿孔。

In combination with the geological features of the ga wells in West Sichuan, such as multi-payzone high pressure gradients and a large lithological change in channel sand bodies, etc., the casing cementing and perforation completion were adopted for the main well and branch holes in the well group and the interzonal pressure seals of the main well and branch holes, and the separate well fracturing and producing were all realized through a completion string with dual-tubing and dual-packer.

结合川西地区气井多产层、高压力梯度、河道砂体岩性变化大等地质特点，该井组主井眼和分支井眼均采用套管固井、射孔完成，通过双油管和双封隔器的完井管柱实现了主井眼和分支井眼的层间压力分隔和分井压裂、分井采气。

This paper establishes mathematical models of unsteady and Non-Darcy low speed flow through the porous media and the double porous medium, and has obtained their solutions in an infinite reservoir through Laplace transformation, and their long time asymptotic solutions has been worked out, solutions on a bounded reservoir has also obtained through finite integral transformation and Laplace transformation.

从现场上各种水淹的实际资料来看，同一水动力的非均质油层系统中，渗透率相对较高的部分水洗之后，渗透率相对较低部分的油层却可以原封不动。而且，其渗透率可达达西级，含油饱和度可达80％以上。相对流动比(即同一水动力的非均质油层系统中，小层平均渗透率的最大值与其中不流动部分的小层平均渗透率的最大值相比)的比值在各种油层的生产实例中十分相近。一般的分布范围为3—7，常见的为4—6。实验室结果和生产实践基本相同。简单的注水和压裂对这一比值几乎无影响。

Acid-fracturing treatment and testing technology level have great impact for testing production. The reservoir can be damaged easily and the uncertainty for calibrating log interpretation will increase according to testing conclusions.⑶ Lithology complex (quartz sandstone, lithic sandstone, arcose), the reservoir has different characteristics with different lithology. Conventional log interpretation methods can not accurately identify the various sandstone.

酸化压裂和试油工艺水平对测试产能的影响很大，储层容易被伤害，使根据试油气结论进行测井解释标定的不确定性增大；⑶岩性（石英砂岩、岩屑砂岩、长石砂岩）复杂，不同岩性的储层具有不同的特征，常规测井解释方法无法准确的识别各类砂岩岩性等。

According to the space distribution characters of tectonic-sequence-based lithofacies and paleogeography, it is showed that three types of hydrocarbon source-rock including carbonate rock, clay and coal in Permian mainly are developed in transgression and maximal sea flooding of two order sequences, and they deposite respectively on platforms with gentle slope in craton, in rift basins and around old lands.

构造-层序岩相古地理的空间展布特征表明，二级层序的海侵期和最大海泛期是二叠纪烃源岩发育的主要时期，分别在克拉通的缓坡台地上、裂陷槽盆和古陆周缘形成了碳酸盐岩、泥质岩和煤系三类烃源岩。

The results indicate that, the inte r face of laminated composites plays a significant role in fatigue crack growth. T he fatigue crack propagation is arrested by the interface delamination in the ex plosive bonded LY12 laminate.

结果表明，层合板中的层间界面性能对其疲劳性能具有重要影响，在LY1 2 爆炸复合板中，垂直板面L-S取向和L-T取向的疲劳裂纹在扩展过程中都发生了明显的止裂。

Finally, we selected Gemini surfactant GNP, GTB and trimeric surfactant TNP to be used as emulsifier to achieve cationic slow breaking and quick-setting bituminous emulsion.

与结构类同的传统型乳化剂相比，Gemini表面活性剂GNP和GTB以及三聚体阳离子表面活性剂TNP具有更高表面活性和较强的荷电强度，因而更适用于慢裂快凝乳化沥青稀浆封层道路施工技术，其表面活性剂的结构对稀浆封层沥青乳液与矿料的拌和时间有重要影响，其拌和时间由长到短依次为：TNP＞GTB＞GNP。

The refracture orientation depends on the stress field in vertically-fractured gas well.

对于处于高含水期开采阶段的井，由于老裂缝控制的原油已接近全部采出，必须实施改向重复压裂，在油气层中打开新的油气流通道，更大范围地沟通老裂缝未动用的油气层，大幅度增加油气产量，进一步提高油气藏开发效果[1]。

In order to insure performance of intercrystalline corrosion resistant and hot cracking resistant, structure of surface layer of weld metal should be austenite and 4%～12% of ferrite.

为保证复层焊缝良好的耐腐蚀和抗裂性能，采用25-13型铬镍奥氏体焊条堆焊，复层的组织应为奥氏体和（4％～12%）的δ铁素体。

The significant differences existed in lower epidermis among materials:in 2 splitting-resistant cultivars,their anticlinal walls had clearly sinuous ridges and the periclinal walls had equal thick ornamentations of cuticles; the defensive cells were rounded cuticles of projected ridges,and epidermal cells were covered with dense powder.

材料间下表皮微形态存在较显著的差别：耐裂材料的垂周壁上有明显的波状嵴，平周壁上有加厚的条纹状角质层纹饰，保卫细胞四周角质层褶皱较多、起伏较大，表皮细胞上覆盖有大量的粉状或颗粒状蜡质。

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。
