含水率

The study show that the frozen earth in this area is mainly silty clay. The content of the dissolvable solt is relative high,which is 12.01%, and the main salinity is NaCL and KCL. The research also revealed that frozen intensity would ascend jumpily when the water contend in the soil reached its optimization( 10.61%) and kept rising,and this phenomena got more obvious with the decrease of the temperature. Between 0C and 10C, the frozen intensity vared very obviously, when the temperature is under -10C, the variety of frozen intensity got gently, and the change is not obvious. The frozen strength was influenced by the solution thickness in the soil hole.when the thickness increased, the frozen intensity decreased.

研究表明：那曲河地区冻土区冻土主要为颗粒较细小的粉质粘土：土样易溶盐含量较高，为12.01％，主要盐分为氯化钠NaCL和氯化钾KCL；该地区冻土土内水分达到最优含水率10.61％并继续增大时，冻结强度有个跳跃式的上升，这种现象随着温度的降低而愈明显；由0℃到-10℃时，冻结强度变化十分明显，温度下降到-10℃以后，冻结强度变化趋于平缓，变化不甚明显；冻结强度受土样孔隙中盐溶液浓度的影响，盐溶液浓度增加，冻结强度减小。

In the process of wood drying, because that the dry rate on the surface of wood is ten times than which inside, the moisture content of wood on the surface reduce to the fiber saturation point first, and begin to shrinkage, but the moisture inside content of wood is far higher than the fiber saturation point, the higher the standard criterion in wood drying, the more obvious of shrinkage.

摘 要：在木材干燥过程中，由于木材表面水分的蒸发速度比木材内部水分移动的速度大10倍左右，因此木材表面的含水率首先降低到纤维饱和点，并开始发生干缩，而此时木材内部的含水率还远远高于纤维饱和点，干燥基准越硬，这种现象越突出，木材发生开裂的可能性就越大。

The free water in wood is very closely related to the density change of wood during drying, so that the sound speed measured by tap tone completely obeys the physical law relating sound speed and properties of solid materials. 2. When moisture contents are higher than the fiber saturation point, the weight changes or the moisture content changes of the wood can be estimated with high accuracy by measuring the changes of sound speed using the tap tone method.

试验结果显示：木材中之自由水分在打音时完全表现在生材之密度变化上，因此打音音速完全遵守音速与材质关系之基本物理定律，故在含水率高於纤维饱和点之生材状态，利用音速变化来推定木材重量变化或含水率变化具有相当高的精度，是合理可行的。

Control in 25 ％ normally without dry wooden keel moisture content, and eligible wooden floor moisture content is in commonly 12 ％, humidity has differred congress to make wooden floor sucks tide quickly, cause blowout of face of the arch since the floor, lacquer.

未经干燥的木龙骨含水率通常在25％左右，而合格的木地板含水率一般在12％，湿度差过大会使木地板快速吸潮，造成地板起拱、漆面爆裂。

Keel is not moistureproof: Be in normally without dry wooden keel moisture content 25% the left and right sides, and eligible wooden floor moisture content is in commonly 12%, humidity has differred congress to make wooden floor sucks tide quickly, cause blowout of face of the arch since the floor, lacquer.

龙骨未防潮：未经干燥的木龙骨含水率通常在25%左右，而合格的木地板含水率一般在12%，湿度差过大会使木地板快速吸潮，造成地板起拱、漆面爆裂。

The result indicated that, The small leaf oak bough moisture contentand bough's height above terrain has the remarkable relations, itsmoisture content distribution elevates along with bough's on positionbut gradually rises.

结果表明：小叶青冈树干含水率与树干的离地高度有着显著的关系，其含水率的分布随着树干上的位置升高而逐渐上升。

Delineation result based on the improved ant clustering indicated that the study area could be partitioned into two irrigation management zones. Soil field capacity, saturation moisture content and permanent wilting point in Zone I were greater than those in Zone II, which indicated that soil in Zone I had stronger drought resistance than that in Zone II under the same climate conditions. Delineation of irrigation management zones could provide references and data support for site-specified irrigation management.

改进的蚁群聚类分区结果表明，研究区可划分成2个灌溉管理分区，I区土壤的田间持水率、饱和含水率和凋萎含水率均较II区大，表明在相同的气候条件下，I区的土壤耐旱能力较II区强，分区结果可以为精准灌溉的分区管理提供参考依据和数据支持。

By field and indoor test, the paper measures soil physical property, soilmoisture constant and soil water movement parameter, provides the soil specificgravity , the soil apparent density, the soil fraction, the soil field moisturecapacity, the soil saturated moisture capacity, the soil percent moisture content ofcom germination and seedlings emergence, the corn wilting point, and alsoestablishes the equation of soil water retention curves, the equation of soil waterdispersion coefficient and the relationship between pressure and soil apparentdensity, and so those provides the parameter for numerical simulation.

Through an analysis on mud-clogging mechanism of suction nozzles on wet type sweeper, a concept is suggested, that water ratio in dust nearing the wall of suction nozzle duct should be decreased so the mud stickiness can be controlled under a critical value and not sticking to the duct wall whereas water ratio in central dust passage of the duct is properly increased to satisfy effective dust absorbing. On the basis of the concept, a water spraying device is designed with improvement for suction nozzles. In the device, the water hole numbers, diameters and distribution along the nozzle circumference as well as initial direction of water spraying are all determined according to concrete suction nozzle structures.

通过对湿扫型道路清扫车的吸嘴易被泥土堵塞的机理分析，提出降低吸嘴流道近壁的尘土的含水率，控制泥块的黏性处于临界黏性以下，使泥块不黏附于流道壁面；而将吸嘴流道中心部位的尘土的含水率适当加大，以满足有效压尘的解决思路，并根据这种思路改进设计了一种吸嘴喷水装置，按不同吸嘴的具体结构确定孔数、孔径、孔沿圆周的分布规律和喷水的初始方向等要素。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
