In culture, spores germinated two weeks after sowing. Gametophyte development is of the "Marattia" type. Gametophyte shape changed from circular, to cordate, to branched. Antheridia and archegonia appeared 10 and 12 months, respectively, after spores were sown.

培养时其孢子在洒播二周后开始发芽；配子体以「观音座莲舅」型发育，配子体生长过程由圆形转心脏形再形成分支。

Scanning electron microscopy showed that the spores were shrinking and collapsing, and the mycelium walls were ramified and nodulated under combined application of Na2SeO3 65.714mg/kg+LaCl3 53.002mg/kg. Furthermore the surface ornamentation of cystidia became fuzzy and disappearing, and some cystidia were disappearing and collapsing.

扫描电镜观察结果表明，与对照相比，中浓度硒镧配施（Na2SeO3 65.714mg/kg + LaCl3 53.002mg/kg）时，孢子由正常椭圆形变成全部萎缩，菌丝粗壮；囊状体在较低硒镧配施浓度（Na2SeO3 43.810mg/kg + LaCl3 35.335mg/kg）处理时表面纹饰模糊、消失，个别囊状体破裂，表面带有藤蔓状的组织。

There is a polarized organelle, Golgi complex consisted of several saccules and some vesicles beside the nucleus and there are some osmiophilic bodies beneath the parasite pellicule.

结果表明，配子体是一渐进发育的单核、惰性虫体，其核旁有一个由扁平囊和泡状小体极性排列组成的细胞器———高尔基体，虫体被膜下有嗜锇小体。

This paper puts forth the method of equivalent section for the analysis of symmetrically reinforced masonry compression member with rectangular section and small eccentricity , studies its accuracy and unifies the methods for such similar sections in reinforced masonry structure and RC structure.

提出了配筋砌体矩形截面小偏心受压构件对称配筋的等效截面法，论证了其精确度，使此类砌体构件和混凝土构件在计算方法上达到统一。

In terms of the obtained values of parameters, it is demonstrated that the covalency of the bonding between Mn〓 and ligands in SrTiO〓: Mn〓 is stronger than the one of the bonding between Cr〓 and ligands in SrTiO〓: Cr〓.

通过分析得到的常压参量值，揭示了在SrTiO〓：Mn〓中Mn〓与配位体之间的共价作用比SrTiO〓：Cr〓中Cr〓与配位体之间的共价作用更强。

Results of non-reducing sodium dodecyl sulphate polyacrylamide gel electrophoresis of the supernatant and aggregate precipitate formed in refolding process show that except being refolded to native egg white lysozymes, the reduced-denatured lysozymes can also form the aggregates with molecular weights being separately about 30.0 and 35.0 kD, while the reducing SDS-PAGE and the refolding results in the presence of sodium dodecyl sulphate show that these aggregates are formed chiefly through the misconnection of disulfide bonds between the reduced-denatured lysozymes, and the aggregate precipitates are formed through the non-covalent interactions between the aggregates with molecular weight being about 30.0 kD.

复性过程形成的上清和集聚体沉淀的非还原电泳结果表明，除了能复性成天然态的溶菌酶分子外，还原变性蛋白溶菌酶同时还能形成分子量分别约为30.0KD和35.0KD的蛋白溶菌酶分子集聚体；而它们的还原电泳和在SDS存在时的复性结果表明，这些集聚体主要是通过还原变性蛋白溶菌酶分子间的二硫键错配而形成，而集聚体沉淀则是通过分子量约为30.0KD的集聚体分子之间的非共价相互作用而形成。

The theory of multibody system dynamics is used to simulate valve trains' kinematics and dynamics characteristics, and the methods of establishing and analyzing the multibody system dynamics model for valve trains are discussed.

运用多体系统动力学的原理来模拟配气机构的运动学和动力学特性，讨论了配气机构多体系统动力学建模和分析的方法。

Campo Vieje has four types of wine: the white wine is fermented in the oak barrel for 4 to 6 months. The wine fluid is refined and fresh, with a fruit and vanilla fragrance. The structure is well balanced and suitable for smoked fish and white meat. Crianze is full of the aroma of ripe fruits, together with the fragrance of licorice. It tastes tender, elegant, and as smooth as velvet and will taste better with half-baked beef steak or mutton chop. Reserva is a very rich and mellow wine, perfect for meat.

帝国田园共出品四款酒：帝国田园白酒，在橡木桶发酵4-6个月，酒体典雅爽快，带野果和香草香味，酒体结构平衡，适合配烟熏鱼和白肉；帝国田园陈酿Crianza富有成熟果实的浓香，加上甘草的香味，饮之如天鹅绒般地柔软优雅，配上半熟的牛排、羊排口感更佳；帝国田园珍藏Reserva是一款非常浓郁、醇厚的葡萄酒，最宜搭配肉类食物。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
