By recognization of paleo crust of weathering, ravinement surface, and analysis of sedimentary sequence and stratigraphic stacking patterns, many sequence boundaries are discovered.

层序地层研究认为，陆上风化暴露面、地层截切面的识别及沉积相序、地层堆积类型的分析是鉴别该套地层层序界面的主要方法。

Highprecision sequence stratigraphy was applied to divide and correlate the different sequence stratigraphical units from the Upper Cretaceous to plaeogene in the Biyang depression, and a sequence stratigraphic framework which can correlate the different sequence stratigraphical units was set up to point out that the ramp region of the northdepression is an oil and gas reservoir featured by altitude progradational delta and complex fault blocks, the inner belt of the north slope hinge zone is a low order faultlithologic oil and gas reservoir, the development stages and high order terms of the deep depressed area is a fluxoturbidite and sublacustrine fan lens trap, and the south actic region is a lithologic hydrocarbon reservoir development area.

运用高精度层序地层学的理论，系统地划分和对比泌阳凹陷上白垩统至古近系不同级别的层序地层单元，建立了凹陷内各级层序地层单元的对比框架，指出凹陷北部斜坡带为高位进积三角洲复杂断块群油气藏，北部斜坡枢纽带内带为低位扇断层-岩性油气藏、深凹区湖扩展期和高位期为滑塌浊积体及湖底扇透镜体圈闭，南部陡坡带为岩性油气藏发育区。

A set of spectific primers was syn thesized according to HBV DNA sequence of Chinese strain, the whole X region was amplified by PCR method from the serum of 9 patients with chronic HBV infection , and then the PCR products were subcloned into pGEM Teasy vectors. Clones were randomly selected to be sequenced. Comparison of the cloned sequence was made to find the difference. After being compared, each sequence of selected clones is o f difference. The point mutation scattered through X region. Deletion mutations were detected in 19 clones of 37(51.4%), which caused different carboxyl endings of X protein. There is a hot region (after 123 aa code) where deletion mutation frequently happens.

以中国株HBV基因序列为依据，设计特异性多聚酶链反应引物，自9例慢性HBV感染患者血清中扩增HBV X基因，克隆入pGEM Teasy质粒，随机挑选克隆进行D NA测序以确定病毒的变异程度。37例测序结果提示来源于不同患者HBV X基因序列高度保守，但每个序列均不一致。X区除了存在广泛的碱基点替换突变外，序列的缺失突变占测序克隆总数的51.4％（19／37）；氨基酸缺失及移框突变多发生于123位氨基酸残基之后，可导致X蛋白多种羧基端形式。

Marsh made important contributions to it later. Titman and Wessels combined the capital structure influence factor theory with the pecking order theory until it became part of the mainstream capital structure theory.

Titman和Wessels把资本结构影响因素理论与Myers等人的优序融资理论结合起来，既用优序融资理论来支撑资本结构影响因素理论，又用资本结构影响因素理论来印证优序融资理论，这才把这个非主流理论融入到资本结构的主流理论里。

This model is incompact and unorderly.

序编又可分为形式序编和实质序编。

In the eastern platform and its marginal reef tracts, it consits of TST composed of 4-7 aggrading parasequences and HST composed of 2-3 minor-prograding parasequences and condensed sections, 35-40 parasequences can be recongnized in the Late Permian.

东部的碳酸盐台地和台地边缘区，由4-7个副层序叠复加积的海进体系域和2-3副层序叠复的弱进积的高位体系域或密集层组成，整个晚二叠系包括35-40个副层序。

We identified the most conserved sites in the GLUT1 and found out a new motif which is probably crucial for the selectivity of GLUTs for the transported sugars like QLS motif.

在GLUT1中，除已经验证QLS和QLG这两个重要的模序外，我们还发现了另外新的一个非常保守的模序，该模序的功能可能和QLS类似，是GLUT1转运葡萄糖所必须的。

The hardware circuit of detecting and rectifying phase sequence is designed and the software design method is given.

设计了矿井电网综合保护中相序检测和相序调整的硬件电路，提出了相序检测在软件设计中的实现方法。

One second-order stacked sequence usually consists of a retrograding stacking third-order sequence set and a prograding stacking third-order sequence set.

一个二级叠加层序内通常发育一个退积的三级层序组和一个进积的三级层序组。

The authors took the Maocaojie section as a typical Permian section, which includes 13 grade 3 sequences that can be divided into two groups: the early craton basin sequences and the late interpolate rifted basin sequences.

以建始县茅草街二叠系剖面为典型研究剖面，将研究区二叠系划分为13个Ⅲ级层序，可分为早期克拉通盆地层序和晚期板内裂陷盆地层序两种类型。

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。
