结果表明：在玉米生长初期以棵间蒸发为主，其后则是以植株蒸腾为主；玉米在30～40 cm土层吸水速率达到最大值；玉米灌水量为田间持水量的70%与85%对土壤0～80 cm土层贮水量的贡献是相等的，并且高肥力在一定程度上可增强根系的吸水能力，高灌水可增强玉米根系对养分的吸收利用，但对于提高水肥利用率来说，理想的处理为中肥中水。

The results indicated that the water resources renewability in the Yellow River Basin was in middle level or below, and the whole basin's water resources renewability was very bad. Water resources social renewability of Presidial Cities in the Yellow River basin was in general level, and the others were worse than Presidial Cities, so the main cities' water resources social renewability in the Yellow River Basin was not good generally.

A pulsator is placed on the inner bottom of a washing/drying tub which is open on its upper side, wash water is introduced through a circulating water passage by the pumping action of the pulsator being rotated, and a discharge opening is provided at the top of the circulating water passage to discharge the wash water toward the center of the washing/drying tub .

一种洗衣机，在上方开口的洗涤／脱水桶内底部设有波轮，通过该波轮的泵作用经循环水道而将洗净水引导至洗涤／脱水桶侧壁高度方向中途，并从设于循环水道上方部的喷出口向洗涤／脱水桶中央喷出。

The study on the hardening mechanism of the soft soil with the materials shows that the hardening procedure can be divided into three stages:(1). Hydrating and dissolving stage, when material A and material B of the high-water-content and quick-setting materials respectively dissolve and balance in water.(2). Gel and consolidating stage, when the materials hydrate into calcium crystal and the ion exchange and aggregation of soil particles occur in an alkaline environment.(3). the structure developing stage, when the calcium crystals connect each other, absorb and crystallize the water around; the hydrate remnants, calcium hydroxide, carbonate continuously in water and in the air.

本文对高水速凝材料-软土硬化机理的研究表明，高水速凝材料-软土的硬化过程可分为三个阶段：①水化溶解阶段：主要为高水速凝材料的甲、乙料分别与水的溶解、维持平衡阶段；②胶凝固化阶段：主要为高水速凝材料的水化反应生成钙矾石晶体以及土颗粒在碱性环境中发生离子交换和团粒化作用；③强度增长阶段：钙矾石晶体相互连接，大量吸收周围环境中的水分，并将水分变成自己的结晶水；水化残余物氢氧化钙在水中和空气中发生碳酸化作用。

According to the feature that deformation resulted from water absorption and mildew appear mainly on the rabbet surface of ccf , this paper adopts rsst to spray a special waterproof sealant on rabbet surface of ccf , so that the sealant can get into fiberboard to certain extent by means of capillarity and penetration , blockage the holes between fibers and capillary , cut up passage of water and change the properties of soakage and sorption to water in capillarity and fiber . at the same time , solidified sealant can form a compact waterproof pellicle on rabbet surface so as to prevent water and humidity from fiber ' s expansion and mildewing

针对吸水变形、霉变主要发生在地板企口表面的特征，采用企口表面全封闭法，在复合强化地板企口表面喷涂特殊的防水封闭剂，使其依靠毛细管作用及渗透作用进入板内一定深度，堵塞木纤维之间的空隙及毛细孔通道，截断水分传递的渠道，并改变毛细孔壁及纤维的表面性质以不利于水的浸润与吸附，同时其固化后能在企口表面形成一层致密的憎水薄膜，防止水分、湿气从企口侵入板内引起木纤维膨胀变形、发霉等现象。

As an often used physical model with good theoretical and practical values, StreeterPhelps model has been widely used to study water quality. However, in some special water areas the utilitization of StreeterPhelps model has some limitation as confirming reaeration coefficient often comes from tests in rivers with fast water flow speed with no consideration of wave effects. Furthermore, in practical research in Three Gorges Reservoir, the changing rule of COD appears abnormally. In some water areas far from pollution source, the value of COD changes with time, but does not follow the exponential attenuation rule. This phenomenon can not be explained by former modified StreeterPhelps model.

StreeterPhelps模型是目前进行河流水质研究常用的物理模型，具有良好的理论和实用价值，然而在某些特定水域，该模型的应用受到限制，主要原因是复氧系数的取定多在水流速度较大情况下得到的，而未考虑水面波动对复氧系数的影响，另外，在实际研究过程中发现三峡库区COD变化的规律出现异常：在离排污口相当远的水域，COD随时间变化趋势并不是指数衰减，而是在某个常值附近微小摆动，以往很多修正过的StreeterPhelps模型都无法解释这个现象。
