In addition , the model of interaction of water and temperature between field water vaporization and soil water storage , temperature and millet weight is gotten by field trial . 2 . the ammonia volatilizing of fertilizer is suit to the dynamic equation as y = a + bt , the coefficients in the equation are related to the kind of fertilizer , temperature and water content of soil , and the dynamic equation about ammonia volatilization including water and temperature and the is developed 肥料氨累積揮發量符合零級反應動力學方程y = a + bt ,方程中系數與肥料種類、溫度和土壤含水量有關,碳銨a 、 b值均比硫酸銨高,土壤含水量增大, a 、 b值降低,溫度升高, a 、 b值增大,并由此得到含溫度或土壤濕度因子的肥料氨揮發動力學方程,并建立了含水、熱因子的肥料氨揮發水熱耦合效應動力學方程。

On base of the theory studied , the author developed a package of applied mosaicking software , using microsoft visual c + + 6 . 0 and opengl graphic techniques . the software was tested with field trial data of h / hcs - 017 . digital sea charts generated by the software are satisfactory and meet the hydrographic surveying principles 在理論研究的基礎上,本文利用visualc + + 6 . 0語言和opengl圖形編程技術,開發出一套適用于多波束測深數據的拼圖軟件,可用于h hcs - 017型條帶測深儀數字海圖的生成。

Having established an understanding of cyberculture and its influence on education from intellectual and moral aspects in general , the fourth chapter is to propose a solution on the problem of how to adapt internet for quality education . virtual university . a model under field trials would be introduced , which would help readers make comparison between learning in traditional classroom and the virtual classroom 在對網絡文化有了清楚的認識,并了解了它對德育及智育造成的影響之后,第四章將對如何利用互聯網進行素質教育提出一個解決辦法:虛擬大學,并具體介紹一個正在現場試驗中的模式。

It is also demonstrated in the field trials that some exotic substance have substantial influence on as uptaking by pteris vittata , indicating the significance of applying proper chemicals into the soil to be remidiated in improving remediation efficiency 研究表明,不同地域生長的蜈蚣草外形指標和砷富集能力存在著很大的差異;另外,一些外源物質也影響蜈蚣草對砷的吸收,添加外源物質是提高蜈蚣草砷污染土壤修復效率的一個有效措施。

Although most field trials of such insects are years away , experts say that the science has advanced rapidly and that regulators need to begin establishing rules now for assessing their potential effects on the environment and public health 即使這些基因改造昆蟲的相關田野研究已有數年,專家卻認為隨著科學的快速進展,管理者必須著手建立相關法規,以評估基因改造昆蟲對環境與民眾健康的潛在影響。
