At the same time, the rhizosphere is favourable to the nitrification, the rhizosphere effect R/S is about 4.5;②The loss rate of -N in 24 h in flooded and anaerobic incubation is 52%?

58％，占第10天的55％？71％，且表土层-N的消失率比底层土大；③参与同化反硝化作用的还原酶活性较强，在培养24h后，被还原的基质数量占加入基质数量的70％？

The special thing about Prego is that it offers the most complex variety of patterns and, of course, the composition of its materials that are made of an original composite of layers.

prego特别之处在于它提供了多种模式和最复杂的，当然材料所组成的复合材料制成的一种原始土层大量的一部分地板是一种防水材料，其目的是提供均匀、尺寸稳定性。

Duration of inversion temperature near ground surface is longer, air temperature is lower, air humidity is higher and water surface evaporation of 20cm standard pan on the top of canopy is generally lower under sprinkler irrigation condition than those under surface irrigation condition.

喷灌跟地面灌溉相比，喷灌条件下近地面出现的逆温时间长，空气温度低，离地面1～4米高度范围内空气湿度大；冠层顶部20cm蒸发皿水面蒸发量小；喷灌条件下0～60cm土层内土壤含水量较高且变幅较小，白天地表温度低，晚上地表温度高。

Lanyang Plain is covered by the Holocene alluvium of the Quaternary Period, which is relatively young in geological age, with various thicknesses of soil layers. The soft soil layers are easily to be compressd under construction loading and subsequently cause the settlement problems.

兰阳平原为第四纪全新世冲积层所覆盖，地质年代轻，土层厚度深浅不一，其组织质地较疏松软弱，易受外力影响而发生地层压缩，进而形成地层之垂直变位等问题。

An optimized approach for single-hole method of shear wave velocity measurement is presented.

针对工程中广泛采用的单孔法剪切波速测试，提出了一种基于互相关函数计算土层剪切波速的优化算法。

Due to the different nature of soil layers in the foundation, causes of embankments landslide on soft ground are complicated.

水利建设中的基础土层性质差异较大，所以软基上的堤防滑坡成因复杂。

Burrowing in the dry, hard soil of the Kalahari Desert in southwestern Africa is tough work, so the lazy group spends this time eating and sleeping.

在西南非洲的喀拉哈里沙漠中，挖掘干燥坚硬的土层是项艰巨的工作，而懒惰的那帮鼹鼠群却在睡眠和吃喝中打发着时间。

The red clay and mantle rock soil distributed on the both sides of gully with rich ground water were better for shallow-root trees to grow,and could obtain better effects if planting in scientific mixed planting.

由于长期水蚀切割作用，土层依次流失，使底层土壤逐渐被暴露了出来，从而形成了从山顶到沟底依次为黄绵土、红

Lay a ground cloth on the fire site and then spread the soil into a circular, flat-topped mound at least 3 to 5 inches thick.

在生火的地方平铺上一块地席，然后撒上沙土成一个圆形，覆盖的土层至少需3-5英寸厚，沙土的厚度对土地的隔热保护作用至关重要。

The shear modulus and damp ratio characteristics of typical strata are achieved in the dynamic test, based on GDS triaxial dynamic system.

利用GDS三轴仪对工程场地内的原状土样进行了室内动力试验，获得了各主要土层的动弹性模量与阻尼比。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
