总结出了适合这种混合沉积层序的相模式，依据这种相模式对本剖面石炭纪的岩相古地理进行了简单分析。

The influence on absorption coefficient brought from shape choice with cylindrical or cone-shaped cavity, square or hexagonal profile, from different closure as air or water, from different material properties and structure sizes, are analyzed based on the numerical calculations. Some general characteristics are summarized. It shows that lowest resonance frequency of sound absorbent coefficient is inversely proportional to volume of cavity and sound absorbent coefficient is proportional to perforated percentage.

2通过数值方法研究了吸声结构内腔为圆柱腔和圆锥腔、基材的剖面形状为正四边形和正六边形、不同背衬、基材材料特性、尺寸大小对整体吸声效果的影响，总结了这些情况下非旋转对称吸声结构的声学特性变化规律，得出腔体体积越大，吸声系数最低共振频率越低；穿孔率越大，吸声系数越大的结论。

Therefore, the subsidence analysis presented here is truncated at the top of the continuous Cenozoic stratigraphic section.

因此，这里提出的沉降分析被截断在连续的新生代地层剖面顶部。

The system consists of four parts such as Data Management of Product Model,Finite Element Analysis, Optimal Design and Graphics Drawing; and its main work is searching for an optimal scheme of chief axis with Sequential Quadratic Programming Method by finite element static and dynamic characteristical analysis of the axis and saving the results of design as documents or outputing them.

系统出产品模型数据管理、有限元分析、优化设计和图形绘制四部分组成。通过对车床主轴二维垂直剖面力学模型的有限元静、动态特性分析，采用序列二次规划的优化设计方法寻求主轴设计的优化方案，并将优化设计结果形成文档或输出。提出产品设计模型的概念，通过它可自动生成有限元分析模型、优化设计模型和图形模型三个子模型，将有限元分析、优化设计、图形绘制三部分结合在一起。

The border of Ehuling group and Daguding group was renewed.it concluded that volcano rocks of former subcycle and latter subcycle volcanic activities all came from the same source of magma,according to their chemical compositions and their chondrite normalized REE patterns.

对如意亭剖面鹅湖岭组与打鼓顶组的界线进行了重新厘定，对早晚两个火山活动旋回火山岩的化学成分、稀土配分特征进行了比较，得出了两旋回火山岩系属同一岩浆源的不同阶段演化产物的认识。

The Chondrite normalized REE pattern shows typical enrichment of LREE, with ∑REE peaking up to 318 mg kg^(-1) in central layer of the profile. Both Ce and Eu have a similar trend of variation in the profile, i.e. positive anomaly-negative anomaly-positive anomaly from bottom to top. The highest ∑REE value occurs where negative Ce and Eu anomaly and relatively higher Fe(superscript 2+)/Fe(superscript 3+) values also occur.

剖面稀土元素分布型式为轻稀土富集型，∑REE在风化壳中部达到最高值318 mg kg^(-1)，剖面上Ce和Eu均呈正异常－负异常－正异常变化趋势，∑REE最高值出现在Ce和Eu负异常和Fe(上标 2+/Fe(上标 3+)较高层位，∑REE与Fe2O3显著正相关。

Tunnel boring machine is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata.

隧道掘进机是一台机器，被用来挖掘一个横截圆剖面的隧道，穿过各种土壤和岩层。

Through observations and measurements, and collect and record claypan from boundary strata section, We analyze the composition of trace element geochemistry.

通过对广元、江油、峨眉山、攀枝花4个地区6个界线地层剖面的实地观察和测量，采集界线附近的粘土岩，分析了该区微量元素地球化学的组成特征。

The coefficient of variation of bulk density and field capacity fluctuate with depth of soil.

饱和含水量和田间持水量的块金值在剖面上变化趋势相同。

In cold desert soils, rubification results in relatively high concentrations of Fe〓 in soil profile. Stained depth increases progressively with time.

土壤剖面上部的染色作用也比较显著，是由于土壤母质中含铁矿物的氧化作用造成的。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
