Based on experiments, the movement of the wetting front was studied in clayloam, loam, and in sandy soil under point drip irrigation, and the effects of soil types, soil density, soil initial moisture, dripper discharge, and drop water to the movement of wetted front were analyzed.

以试验为基础，针对重壤土、中壤土、砂壤土研究滴灌点源入渗的湿润锋运移规律，分析土壤种类、土壤容重、土壤初始含水率、滴头流量、灌水量等主要因子对湿润锋运动的影响。

By mono-factor analysis of the point drip infiltration,the horizontal and vertical movement distance of soil wetting front were not only in close relation with dripper discharge and drop water,but also had good power functional relation which exists with the soil characteristic ( soil density, soil initial moisture).

以室内试验为基础，测定了重壤土、中壤土、砂壤土在不同滴头流量、不同灌水量下的点源入渗运动过程，通过对点源入渗特性的单因子分析表明，湿润锋水平、垂直扩散距离不仅与滴头流量、灌水量关系密切，与土壤特性(土壤容重、初始含水率)也存在良好的幂函数关系，得出了以土壤物理参数和湿润比及湿润深度为基础的点源滴灌滴头流量的设计模式

The adsorption and desorption behaviors of S-metolachlor in three different soils were investigated using the batch equilibration method.

采用平衡振荡法研究了精异丙甲草胺在粘壤土、粘土及砂壤土中的吸附和解吸附行为。

Soil moisture sensors based on principles of Time Domain Reflectometry,Frequency Domain and a new type of soil moisture sensor based on Standing Wave Ratio developed by China Agricultural University were evaluated with typical sandy loam,loess,peaty sand and leady loam from northern Germany.

该文针对时域反射法、频率分解法型土壤水分传感器和中国农业大学研制的基于驻波率原理的新型土壤水分传感器，在德国北部典型的沙壤土、黄土、含煤沙土及含铅壤土土样上做了试验。

Block the choice of Melon choice Leeward Sunningdale, topography Gaozao, Qiancha not of the Cucurbitaceae vegetables with drainage and irrigation conditions of sand loam or loam plots.

地块的选择厚皮甜瓜选择背风向阳，地势高燥，前茬没有种过葫芦科蔬菜的具有排灌条件的沙壤土或壤土地块。

The column experiments on sandy loam and loam showed (water content from oven-dry to saturation) that different Ts/Ta values lead to water content deviation 0.001?

用烘干至饱和含水量的砂质壤土和壤土的土柱试验结果表明，选用不同的Ts/Ta值，引起的含水量偏差分别为0.001？

Results show that the change trend of growth is homogeneous, but it plays a different role in the growth of seedling height, ground diameter and leaf number; that for seedling height, peat soil is the best and red loam comes the next, for ground diameter, red loam is the best and peat soil comes the next and for leaf number, peat soil is the best, and red loam with nutrient soil named "zhidele" comes the next; and that in a growth season, the law of monthly increment of seedling height and leaf number is "fast-slow-fast-slow-stop" while the monthly increment of ground diameter is relatively stable.

结果表明，4种不同基质条件下油茶生长量变化趋势基本保持一致，但对苗高、径粗、叶片数的生长影响不同，对于苗高来说，泥炭土最好，红壤土次之；对于径粗来说，以红壤土最好，泥炭土次之；对于叶片数来说，以泥炭土最好，红壤土和植得乐营养土次之。在生长期内，幼苗苗高和叶片数月增长呈现出&快－慢－快－慢－停止&的规律，而幼苗径粗增长量相对稳定。

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。
