结果表明，传统灌溉方式下，优化氮素处理保证了番茄产量，与传统氮肥处理相比，追施的氮肥数量减少了48%；在番茄的主要生育时期内，采用每次灌溉至田间持水量及固定灌额处理的灌溉量分别比传统灌溉处理减少46%和30%；采用同样指标所推荐的氮肥追施数量也分别减少14%和10%，明显减少土壤–蔬菜体系中氮素的表观损失，减轻了由于过量施氮而对环境造成的影响。

Five-Dragon Resort is an important part Of places Of interest in Mt,WuDang,It lies in the west Of WuDang Mountain,Because Of long history and poor transport facilities,this region iS regarded as a place to be developed,There are more than 10 historical scenic attractions,such as Five—Dragon Palace,the General Temple,Hidden--Immortal Rock,Golden--Flower Cave Humane Dignity Palace,The Langmei Temple etc,and a national park Of about 280,000mu,On the southeast it is connected with the Golden Palace and the Southern Rock Palace,The famous car city Shiyan and a highway from Shiyan to WuHan lie to the north and west Of it,It is favorably endowed by natural forest landscape and also rich in humanism relics,So it has high development value and considerable economic benefits,with the development of tourism economy and improvement of visitors'demands,We have decided to build a road in Five-Dragon Resort to further develop and protect its resources

五龙景区是武当山名胜风景区重要组成部分，位于武当山西神道。由于历史的原因和景区交通不便，该景区属一个尚待开发的景区，景区内有五龙宫、将军庙、隐仙岩、金花洞、仁威观、姥姆祠等10余个文物景点，以及28万亩的国家级森林公园。景区的东南面与南岩、金顶两个景区相连，北、西边与车城十堰、汉十高速公路相依。景区内自然景观、森林景观和人文古迹等旅游资源十分丰富，开发价值大，经济效益十分可观。随着武当山旅游资源的发展，旅客市场的需求，为进一步开发和保护五龙宫的旅游资源，拟修建五龙景区公路。

The substantial behavior of the FCB material is introduced thouroughly in this paper. Generally, the apparent density ranges between 500 and 1500 kg/m3 while the compression strength varies from 0.1 to 1.5MPa. Because FCB is fluid and self-hardening, the flow value is often controlled at about 180?

In the first part, it was investigated the interaction between Pb2+ and La4Ti9O24 ceramic bulk. The result shows that a significant Pb2+ diffusion into La4Ti9O24 ceramic bulk and a significant crystallization of the La2/3TiO3-type phase is clearly observed in the Pb2+ diffusion layer. The reacted zone consists of the La2/3TiO3-type phase exhibits the linear dependence of the square of the thickness, x, on the heat-treated time, t, in excellent agreement with the parabolic law x2 = kt, where k is the growth rate coefficient. The kinetic study thus indicates that the Pb2+/La4Ti9O24 interaction strictly obeys the theory of the reactive diffusion. Furthermore, the experimental k values were used to determine the associated activation energy, Ea, for the formation of La2/3TiO3-type phase using the Arrhenius plot and the following least-square equation, ln =-Ea/RT + A, where T is the annealing temperature, R is the universal gas constant, and A is a constant, resulting in Ea ~ 607 ?b 60 kJ/mol.

首先， 以巨观的方式观察PbO与La4Ti9O24陶瓷体介面的反应现象；利用X-ray绕射分析以及扫描式电子显微镜来观察不同的热处理温度以及不同的持温时间所制作的样品，研究结果发现， Pb2+离子会渗入到La4Ti9O24陶瓷内，同时在Pb2+离子所渗入的区域内会产生新的La2/3TiO3-type钙钛矿斜方晶相；藉由量测不同温度与时间之样品，其因Pb2+离子渗入而产生之La2/3TiO3-type相层厚度之关系，符合反应式扩散机制中 x2 = kt 之关系式(其中 x：扩散层厚度； k：反应速率常数； t：反应时间)；进一步将不同实验条件所得到之反应速率常数值代入Arrhenius方程式ln (k =-Ea/RT + A ，其中Ea：活化能； T：绝对温度； R：气体反应常数； A：常数，可以求得Pb2+离子与La4Ti9O24陶瓷发生反应式扩散所需之活化能为607 ± 60 kJ/mol。

The experimental results showed that, monochloroacetic acid and dichloroacetic acid enhanced photocatalytic hydrogen generation activity, but trichloroacetic acid did not improve it. The amount of produced H_2 increases almost proportionally to the irradiation time within 5 h irradiation. The photocatalytic oxidation of monochloroacetic acid and dichloroacetic acid mainly produced CO_2, HC1 and CH_2O, the photocatalytic oxidation of trichloroacetic acid mainly produced CO_2 and HCl.
