The calcination of the catalysts at high temperature may easily result in theformation of tetrahedral structure Mo species before sulfidation,and decrease theamount of octahedral coordination Mo species.The sinter and loss of the activecomponents would take place during the calcination at overhigh temperature. Meanwhile,the active component could react with support,thus made the activecomponents entered into support bulk phase.

7催化剂在硫化前进行高温焙烧，容易形成四面体结构的钼物种，而八面体配位钼物种减少，且过高的焙烧温度易使活性组分发生烧结，同时可能发生活性组分的流失或与载体发生反应进入载体体相。

The PROTHALLUS of Lycophyta, Sphenophyta, and Filicinophyta, which may be a green structure on the soil surface or a subterranean mycorrhizal structure, is the gametophyta.

石松门、楔叶门、真蕨门的原叶体是位于地表的绿色结构或是位于地下的菌根结构，这些结构便是蕨类植物的配子体。

The fern spore, the original cell of the gametophyte, carries out asymmetrical mitosis to produce a large cell and a small cell. The small cell geminates to a rhizoid by tip growth, and the large cell further divides and develops to become a prothallus.

蕨类植物孢子作为配子体的原始细胞，通过不对称的有丝分裂产生一大一小两个细胞，小细胞萌发出极性生长的假根，大细胞继续分裂发育为原叶体。

The present sandpile experiments with an one-side slope show that the self-organized criticality of granular mixtures is strongly influenced by the non-uniform degree of granular materials.

不同级配散粒体单面坡的已有试验表明，散粒体的SOC与非均匀系数有关。

Ulva, the sea lettuce in which the alternating generations of the life cycle are morphologically identical.

同形性：在某些具有世代交替生活史的藻类中，其孢子体和配子体形态完全相同的现象。

This paper studies the reconstruction of the 3D solidi model based on ICT slicing and presents a new edge matching method and a reconstruction method of solid-model based on surface identification, Volume cell construction and volume mergence.

研究了基于工业CT 切片图形的实体模型三维重构技术，讨论了边界配准技术，提出了基于表面识别、通过逐层体元构造和体元粘合来构造实体几何模型的重建思想，并给出了一个成功的重构实

After 3 years of culture, only 3% of the gametophytes produced a sporophyte.

经过三年的培养，只有3%的配子体产生孢子体。

Which are divided into sporophyte developed special-shaped generational and generational shaped gametophytes developed.

其中又分为孢子体发达的异形世代交替和配子体发达的异形世代交替。

The development of a gametophyte directly from a sporophyte without the occurrence of meiosis or spore formation.

无孢子形成，无孢子生殖，无孢子状态没有经过减数分裂或孢子形成而直接由孢子体进行的配子体发育

The results showed that the techniques could increase gametophyte adhesion rate by over 80%, made the seedlings stronger and the germination quality reach state standard of Class Ⅰ. The growth speed of clone adhesion (8~16 rows) was about 20 days faster than that of normal sporophyte seedling adhesion.

结果显示，这样的措施可使配子体附着率达到80%以上、幼苗健壮、出苗质量达到国家一类帘标准，使克隆采苗自8～16列c期间的生长发育速度较常规孢子体采苗后的生长发育速度快20 d。

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。
