The results showed that the amounts of base cations leached from calcareous soils and coastal solonchak were lower than the cation exchange capacity and the releasing amounts of Al3+ being lower than 0.40mmol·kg-1 all the way under the treatment of simulated acid rain with each pH value from 2.5 to 5.6,so the H+ buffering...

结果表明，石灰土和滨海盐土的阳离子淋溶量低于阳离子交换量，土壤主要处于阳离子交换缓冲范围和碳酸盐-硅酸盐缓冲范围，Al释放量一般低于0.40mmol·kg~(-1)，铁铝土纲系列土壤在阳离子释放总量超过阳离子交换量后，淋溶液pH值急剧下降，此时Al淋溶量明显增加，质子缓冲转向Al缓冲范围，其释放量决定于土壤富铁铝化程度的高低和活性Al含量的多少，紫色土在低pH模拟酸雨淋溶下，由于含大量硅铝率较高的易风化原生或次生矿物，盐基释放量高于CEC，但Al释放量未明显增加，淋溶液pH也较稳定，土壤尚处于矿物风化为主的硅酸盐缓冲范围。

The spores of Cheilolejeunea ventricosa X.L.He were cultured on MS media (without acid and vitamin, pH=6.2, with 1% agar and 1% sucrose). The sporeling development and oil body ontogeny were observed. After a 55-day-long axenic culture, young plants were obtained successfully. Sodium hypochlorite solution was used to sterilize the capsules. Our results revealed that the sterilizing treatment with 0.1% Sodium hypochlorite solution for a period of 5 seconds was optimal. Oil bodies in primary protonemata are nearly homogeneous, but distinctly compound in the leaf cells of the primary leafy shoots.

首次研究了膨叶唇鳞苔的孢子萌发、原丝体和油体发育及配子体发生的过程，结果表明：(1)使用经过改良的MS培养基（不加氨基酸和维生素，pH值为6.2，琼脂和蔗糖浓度均为1%）能在55 d左右的时间利用孢子培养获得植物体；(2)用0.1%的次氯酸钠溶液，消毒5 s是消毒孢子的最佳方案；(3)油体在孢子萌发初期为均一型，到幼叶发生后，成为可见的聚合型，但聚合的程度比野生材料要弱。

Different surface modifiers (benzoate, stearine acid and organosilane) were used to treat plant cellulose/polypropylene composite systems. Effects of surface treatment agents on mechanical properties ( tensile strength and impact strength) were studied.

采用不同的表面改性剂(苯甲酸、硬脂酸、有机硅烷)对植物纤维/聚丙烯复合体系进行了处理，研究了表面改性剂对体系力学性能的影响规律，探讨了复合材料界面粘接机理，分析了力学性能的变化规律。

The content of stone cell was decreased in the treatment of ZnCl2 spraying, and it had no distinct influence on diameter and density to spray ZnCl2.The content of total soluble solid was increased, meanwhile, the titration acid contents were decreased by this way.

喷施氯化锌可以降低石细胞团含量，对直径和密度影响不大，提高了可溶性固形物，降低了核心比和可滴定酸含量。
