, 2014 為探討大顆粒尿素（USG ）在水田之肥效，分別在田間、溫室及室內進行研究。 一、田間試驗： （1 ）同氮素施用量處理USG 深施，不論在榖產量或稻稈產量均為最高。 （2 ）田間試驗除埔心試用外，以66∼88公斤氮／公頃用量深施所得的穀產量與其 它對照肥料施用較高的氮素處理，可以得到較高經濟效益的穀產量。 （3 ）氮肥深施可以獲得較高氮素回收率，而同樣的氮素施用量，均以USG 的氮肥 回收率最高。 （4 ）分析生長期間之植體，USG 深施處理者植體內含氮量皆高於臨界濃度，因此

, 2004 采用以尿素水解为基础的水热合成法制备了Mn取代的镧六铝酸盐催化剂，研究了尿素加入量对所制备催化剂的化学组成、相结构、孔结构及甲烷催化燃烧活性的影响，n(尿素)/n(M^+)(其中M^+为带单位正电荷的金属离子)为1．0时，Mn^2+离子沉淀不完全．所得催化剂甲烷催化燃烧活性较低,n(尿素)/n(M^+)增加到2．0时,Mn^2+离子沉淀完全,催化剂中六铝酸盐相增加，平均孔直径增大。甲烷催化燃烧活性提高,n(尿素)／n(M^+)再增加至4．0时,比表面积降低，六铝酸盐相减少，平均孔直径降低 ...

プリンおよびピリミジン塩基を給与したラットの尿中窒素化合物について
ラットにプリン塩基およびピリミジン塩基を経口給与し尿中の窒素化合物をしらべ次の結果を得た. 遊離のアデニンおよびグアニンを与えた場合,尿中に排出される窒素は尿素アンモニア態のものがアラントイン態よりも多かったが,AMPをアデニン相等量給与した場合はアラントイン態のものが尿素,アンモニア態より多かった.
