It has been shown that transpiration through the stomata amounts to 90% of the transpiration that occurs from a water surface of the same area as a the leaf.

据显示在叶片气孔处发生的蒸腾作用约占同叶片面积相等的水面能够发生的蒸腾作用的90%。

The result indicated that we can get stable homopolymer and copolymer emulsion with uniform size distribution, when the ratio of sodium polyether sulfovinate modified polysiloxane to sodium lauryl sulfate was two, the quantity of the emulsifiers ranged from 6% to 8%, the quantity of initiator ranged from 0.4% to 0.8%, the stirring speed ranged from 200rpm to 250rpm, the polymerization temperature was 80 centigrade degree. As for the copolymer emulsion, the more the TRIS content in the monomers, the larger the water contact angle of their films became, namely, the surface energy of the copolymer films increased with the TRIS content in the monomers. In addition, the glass-transition temperature of the copolymers ranged from high temperature region to low temperature region with the increasing of TRIS content in the monomers.

结果表明:当乳化剂用量在6%~8%、改性乳化剂与十二烷基硫酸钠复配比为2:1、引发剂用量在0.4~0.8%、聚合温度为80℃、搅拌速度在200~250rpm时,得到的均聚物和共聚物乳液稳定,而且粒径分布均匀;对于共聚物乳液来说,随着单体中TRIS含量的增加,所得聚合物膜的水滴接触角增加,即其表面能增加:另外,随着共聚单体中TRIS含量的增加,共聚物的玻璃化转变温度从PMMA的Tg的高温区向PTRIS的Tg的低温区移动。

The existing image matching methods work well in open areas with relatively smooth terrain. However, they still meet many problems in the case of larger scale images of nature, especially in the dense city centers, forestry areas and the textureless regions such as water bodies. The reliability of image matching is still a big issue in these cases. For example, the corners of buildings and some object boundary points sometimes cannot be matched successfully, and there are many blunders in the automatically derived digital surface models that need to be manually removed, which leads to the decrease of the automaticity in digital photogrammetry.

现有大多数立体影像匹配方法对于地形平滑的开阔地带具有较高的可靠性,然而,面对从千变万化的自然界所摄取的影像,现有的匹配方法仍然存在许多问题,尤其是在植被茂密、建筑物密集和水域等区域,影像匹配的可靠性还不高,一些建筑物的角点和地物的主要边界点还不能正确地匹配出来,自动生成的数字表面模型中存在着许多异常值,需要进行大量的人工编辑处理,这在很大程度上制约了数字摄影测量自动化水平的提高。

Among different organ explants from ginger lily, only sheaths and leaves cultured in VW medium containing 5mg/l 2, 4-D、0.5mg/l BA、3% sucrose and 200ml/l coconut water for 3 months could be induced to form embryogenic callus. It could produce lots of germinated or ungerminated somatic embryos per culture directly from the surface of calli after culture in MS medium containing 4mg/l BA and 0.05mg/l NAA. The shoots could develop into intact plants with vigorous appearance after 2 months in culture.

叶鞘及叶培植体在含5 mg/l 2,4-D,0.5 mg/1 BA、3%蔗糖及200 ml/1椰子水的VW固体培养基中,经3个月,可诱导产生具体胚分化能力之愈合组织;并於含4 ms/l BA及0.05 ms/l NAA之MS培养基中,直接由此愈合组织的表面产生数个至数十个数目不等之体胚,2个月后可形成一完整植株。

A critical component in the assessment of the water quality benefits of PFC is whether the relatively low pollutant concentrations observed in this study are a function of removal of pollutants within the pavement, reduced generation of pollutants through reduction in washoff from vehicles, or the lack of accumulation of pollutants on the new road surface.

一个重要组成部分利益的PFC在水质量评估是否相对低污染物浓度在本研究是观察车辆的,缺少或在washoff从功能,通过减少污染物产生的污染物的去除在人行道上,减少污染物积聚在新的路面。

The pollution caused by the washoff of urban stormwater runoff from surface is the critical part of the non-point pollution. With deepened the control of the point pollution, it is serious day by day that the receiving water is polluted by urban stormwater runoff.

城市雨水径流冲刷地面而引起的污染是面源污染的重要部分,随着点源污染治理的深入,城市雨水径流对受纳水体的污染己日益凸现。

Asphalt Pavement will generate various cracks after go into service, because of the immersion of road surface water, the moisture of the pavement structure layer and the subgrade on the both sides of crack will increase, resulted in lower strength of subgrade and pavement.

随着交通量迅速增加,特别是大吨位车辆行车荷载的作用,路基、路面承受不了超载车辆荷载的作用,加快路面的裂缝产生,大大缩短沥青路面的使用寿命。本文对沥青路面裂缝常见形式和裂缝产生的原因进行了分析,同时也提出了相应的防治措施。

The results showed that after the adding starch to the sheet, the viscosity of the PVA solution increased, the dissolution time of the sheet got longer, the rate of enlargement in water was smaller, the rate of moisture became smaller, stretch intensity enhanced and the change of shape diminished; also it could be seen from the surface of sheet that the starch existed in PVA sheet as the shape of conglomerating particle.

结果表明,加入淀粉后,PVA溶液的粘度增大,膜的溶解时间变长,水上伸长率变小,含水率变小,扯断强度增强,形变缩小;通过膜表面观察,发现淀粉在膜中以聚集颗粒状态存在。
