This conclusion is based on three groups of experiments with detached root tips of wheat seedlings: By following the time course changes of NO synthase , superoxide synthase and ABA accumulation under dehydration stress, we found that ABA accumulation was preceeded by the changes of NOS and superoxide synthase. ABA accumulation induced by dehydtrion stress and osmotic stress can be blocked by NO scanvegers and NOS inhibitors, while only dehydration stress-induced ABA accumulation can be blocked by ROS scanvegers. Exogenous applied NO or ROS induced ABA accumulation in root tips of wheat seedlings, and synergistic effects were found between NO and NO. The in planta expereiments also proved that ROS and NO are involved in water stress-induced ABA accumulation.Ⅱ.

证据主要来自以离体根尖为材料的实验：(1)通过检测干旱胁迫下小麦根尖NOS活性、O〓合成酶活性和ABA积累的时间变化进程，发现ABA积累滞后于ROS和NO的变化；(2)抑制剂实验表明，NO清除剂和NOS抑制剂可以抑制自然干旱胁迫及渗透胁迫诱导的小麦根尖ABA积累，ROS清除剂抑制自然干旱胁迫诱导的ABA积累而不抑制渗透胁迫诱导的小麦根尖ABA积累；(3)在非胁迫条件下施加外源的ROS或NO可以诱导小麦根尖积累ABA，ROS和NO之间具有协同作用。

The acidity of HZSM-5 was due to the non-framework aluminum species, i.e., SiAl. The intensity of acid sites of HZSM-5 declined while the quantity of acid sites increased with dehydration temperature, with optimal intensity and quantity of acid sites and maximum toluene conversion of 28.2% at dehydration temperature of 400℃.

HZSM-5分子筛的酸性变化主要是由于非骨架铝物种SiAl的变化而引起，随着脱水温度的升高，HZSM-5分子筛酸中心的强度下降，但酸中心数量增加，当脱水温度为400℃时，HZSM-5分子筛的酸中心强度和数量达到最佳，甲苯转化率为28.2%。

The cause of hard agglomerate formation and its effect on sinterability were investigated. The water-washed ZrO〓-Y〓O〓 powders were found to be greatly made up of hard agglomerates. The ethanolwashed powders also contained a few of hard agglomerates because of uneffective dehydration. Beside, ethanol volatilizes in advance of water during drying because ethanol has a lower boiling point than water, so steric effects of ethanol won't act. However, nearly no hard agglomerate formed in the azeotropic distilled powders, because of effective dehydration and higher boiling point for n-butanol.

研究指出，水洗工艺所得ZrO〓-Y〓O〓粉末几乎完全由硬团聚组成；乙醇洗涤工艺的脱水效果不是很好，并且由于乙醇的沸点比水低，以致在干燥过程中残留乙醇比水先挥发，乙醇的空间位阻效应不能有效地发挥作用，因此，仍然可以导致产生一定量的硬团聚；而共沸蒸馏工艺的脱水效果最佳，且正丁醇的沸点比水高，干燥时残留正丁醇比水后挥发，从而正丁醇的空间位阻效应可有效地发挥作用，因此避免了在煅烧过程中形成Zr-O-Zr键，即共沸蒸馏粉末中不含硬团聚。
