This paper studies the change pattern of soil strength in the different water content as an example of silty clay soil in Beijing area. The results have shown that the changes of water content in the scope of 10-20% have greatly influences on soil strength.

结果表明：随着含水量的增大，土的强度降低，但降低的幅度不一样，当土的含水量在10～20％之间变化时，含水量的变化对土的强度影响极为明显。

The ultra-drystorage is the technique,to lower seedmoisture contentless than 5%and store it at ambienttemperature to gain the same storability as seeds with higher MC at coldtemperature.

超干贮藏就是把种子含水量降至传统的安全含水量(5％)以下，并在常温下贮藏以达到高含水量种子在低温下贮藏的相同效果。

A5B4, holard 25%, irrigation 90m~3/hm~2) was best in single plant yield and 15(A3B5,holard 15%,irrigation 120m~3/hm~2) was excellent not only in grains per corncob but also in hundred-grain weight at different holard and different irrigation.

不同土壤含水量及不同坐水量处理时，平均穗粒数和百粒重均以处理15(A3B5，含水量15%，坐水120m~3/hm~2)为最优，单株产量以处理24(A5B4，含水量25%，坐水90m~3/hm~2)为最佳。

The water content of external layer of root xylem of Kalidium foliatum is highest. In the range of root diameter from 0.3cm to 0.5cm,the most roots diameter are between 0.3cm and 0.5cm.

盐爪爪根的皮层含水量在径级为0.3－0.5cm范围内最高，大于0.5cm含水量反呈下降，而盐节木根径级在0.5－0.6cm范围内皮层和木质部含水量均最高，这可能是盐爪爪和盐节木根系径级分别多集中在0.3－0.5cm和0.5－0.6范围内的原因之一。

The result showed that when soil moisture content is 90% of the relative moisture content,it resulted in an increase in plant dry substance accumulation and strong seedling index ,a reinforce in net photosynthetic rate and root vitality ,and a decrease in transpiratory rate ,compared with the nmrmal irrigation which is 100% of th...

结果表明，土壤含水量为相对含水量的90％（PF值1.6），较常规灌至土壤相对含水量100％，植株干物质积累增大，壮苗指数提高，光合速率、根系活力增强，蒸腾速率降低。因此认为番茄苗床灌溉土壤含水量最佳上限为90％。

The rainfall was highest in August, and lowest in September. The temperature was highest in July, and lowest in May. The average soil moisture content in the semi-fixed dune land in June was less than that in August and equal to that in September. The average soil moisture content in the natural reconverted grazing land was lowest in September, and highest in August.

半流动沙地6月平均土壤含水量小于8月，8月平均土壤含水量等于9月；放牧自然恢复地平均土壤含水量9月最低，6月其次，8月最高；退耕自然恢复地平均土壤含水量8月最低，9月其次，6月最高。

Applied with test of potted plant and measurement absorbency for study physiological response of activity of cell defense enzymes and lipid peroxidation of slash pine's half-sib under water stress. There are 7 families comparison with general slash pine. The contents of superoxide dismutase, catalase, antioxidant, malondialdehyde and the rate of superoxide anion(-O2) generating are mensurated under normal water condition while soil water content is 70% and light water stress while soil water content is 55% to 60% and medium water stress while soil water content is 35% to 40% and heavy water stress while soil water content is 20% to 25%. The test result indicate that either water grads or families of contents of SOD,CAT,AsA,MDA are mighty notable difference. The rate of -O2 generating is notable difference within families. The rate of -O2 generating is mighty notable difference within water grades.

为研究湿地松优良半同胞家系保护酶及脂质过氧化作用对水分逆境的生理响应，采用盆栽试验和吸光度测定结合的方法，以普通湿地松种子为对照，测定了七个湿地松半同胞家系在正常水分状态（土壤相对含水量为70%）、弱度水分胁迫（土壤相对含水量为55%~60%）、中度水分胁迫（土壤相对含水量为35%~40%）和强度水分胁迫（土壤相对含水量为20%~25%）条件下的SOD、CAT、AsA、MDA的含量和-O2产生速率，研究结果表明：无论是不同水分梯度还是不同家系水平，SOD、CAT、AsA活性和MDA含量的差异均达极显著水平，不同家系水平间-O2产生速率有显著差异，不同水分梯度间-O2产生速率差异达极显著水平。

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。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
