The paper discusses various factors which can affect DASY zeolites filtration and exchange by using filtration basic equation, mass transfer equation of heterogeneous reaction and zeolite exchange mechanisms in the production of DASY with vacuum belt filter, finally optimizes the belt filter's operation conditions.

Methods Wistar rat and Kunming mouse were used as experimental animals. Osteoporosis was induced by orally given retinoic acid ( 70 mg · kg-1 · d-1) to the rats for 14 dasy.

方法：维甲酸（70mg·Kg-1·d-1）给大鼠灌胃14d，可导致大鼠的实验性骨质疏松，然后观察药物对动物骨密度的影响；

The LT50 decreased to 4.3 days at the dose of 134.9 conidia per mm2 from 5.1 dasy at 57.7 conidia per mm2. The results indicate that the millet cultures of Z.

在57.7～134.9个孢子/mm~2的接种剂量范围内，致死中时LT（50）从5.1天下降到4.3天。

Gen. Rodzali Daud described the report as inaccurate and incorrect, and said Malaysia's air force is still examining all possibilities.

Rodzali Daud称该报道“失实”，说马来西亚空军仍在调查所有的可能性。

So it was with a sense of mission that Daud turned to working for peace – first with non government organizations and later joining the World Bank.

带着一种使命感，Daud开始为争取和平而努力-起初，他与非政府组织一道开展工作；后来，他加入了世界银行。

" Farmers were barely able to work three or four hours a day, four times a week on average ( during the conflict)," calculates Daud.

“（冲突期间）农民们每周平均只能下地干活四次，每次几乎干不足三、四个小时，”Daud说。

General Daud Daud was killed along with a provincial police chief, two bodyguards and three German soldiers.

杰尼罗•多德多德被杀的时候身边还有警察局长，二个贴身保镖，三个德国士兵。

The relations of the two country appeared twists and turns after Daud came into power, but their relations were normal.
