There are many skin folds in human body which are adapted to the need of movementand also the important marks to divide anatomic regions.i.e.the groin is the skin fold whichexists between lower abdomen and anterior thigh,the gluteal-thigh sulcus is skin fold whichexists between buttocks and posterior thigh.Correspondingly,the skin fold which existsbetween pudendum and superior-medial thigh is named pudendal-thigh sulcus,and flapsharvested from pudendal-thigh territories can be called the pudendal-thigh flaps.

人体体表有许多皱褶，这些皱褶是为了适应运动的需要，同时也是解剖学分区的重要体表标志，如存在于下腹部与股前区的皮肤皱襞称为腹股沟，存在于臀部与股后区的皮肤皱襞称为臀沟，相应地，存在于大腿内上方与会阴部之间的皮肤皱褶可称之为阴股沟(pudendal-thigh sulcus)，在阴股沟区切取的皮瓣即称为阴股沟皮瓣(the pudendal-thighflap)。

据了解，新发现的两处岩画分布于上沙窝镇三眼井村老鸦崖和红水镇原松林村西岔湾，这是继2007年普查队在红水镇的姜窝子沟、中泉乡的板形沟、正路乡的拉牌沟、寺滩乡的画鹿沟之后又新发现的古代岩画。

The relationship of slope and upslope drainage area of the study area is S = 0.074 A-0.1895, and the gully initiation process is an interaction process of hydrological erosion, melt erosion and landslide erosion, the initiation threshold is increased by the biomass.

研究所得的切沟发育临界地形条件为S = 0.074 A-0.1895，研究区切沟发育的过程是受水力侵蚀、冻融侵蚀和重力侵蚀的交互影响的过程，而沟头植被覆盖的增大会导致切沟发育临界条件的增大。

An introduction is made on the application of an air supply low pressure jet aeration system in an improved oxidation ditch in the treatment of the liner board effluent with a detailed introduction and analysis on the commissioning of the operational process.

介绍了采用供气式低压射流曝气系统的改良型氧化沟用于箱纸板废水处理，并对整个调试运行过程进行了分析。改良型氧化沟采用全好氧曝气，沟中不存在缺氧区和厌氧区，抑制了传统氧化沟中的硝化与反硝化作用，降低了营养盐的投加成本，具有很强的抗冲击能力。

Cusp-shaped trenching is China Agricultural University in the course of the study of conservation tillage in the introduction of screening test the Australian soil, and it has buried a strong ability to form a narrow groove (small amount of ground-breaking), ability to automatically back to earth, simple structure, reliable, low cost and so on.

尖角形开沟器是中国农业大学在保护性耕作研究过程中引进、试验筛选的澳大利亚开沟器，它具有入土能力强，沟形窄，自动回土能力强、结构简单、工作可靠，价格低廉等特点。

Chestnut soil in an elevation of 2200-2800 meters ditch horse business, Jackdaws small ditch on the south side of the fire northwest of Chung Ling, Donggou, Zhang Bailu, XIAOLIUGOU, West Osaka Liang, Yan Hua stockade on the south side, the north slope of the Qilian Alluvial fan, a total of 202.56 million.

栗钙土 分布在海拔2200-2800米处的马营沟、小寒鸦沟南侧、火松岭西北侧、东沟、白露掌、大柳沟、西大坂梁、严家花寨子南侧、祁连北坡冲积扇上，共202.56万亩。

From 1998 to 2000, soil moistures of all the positions in the gully watershed reduced continually.

从1998-2000年，随降水量减少，切沟所有部位土壤湿度持续下降，即使在水分条件较好的沟顶和沟坡下部，土壤湿度也仅为8.1%～8.8%，其它部位则都接近于凋萎湿度。

Compared with bed planting,there was higher soil water storage in wheat furrow planting field,however,there was lower dispersion of soil water storage at the same stage on 0~90 cm layer of furrow planting field and the similar dispersion of soil water sto...

从沟播和垄作麦田土壤贮水量差值的分析可以看出，沟播麦田土壤贮水量要明显高于垄作麦田，沟播的同一时期沟垄间的土壤水分差异在0 90cm土层要低于垄作的，而10 0 12 0cm土层就极其相近。

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.
