As the wide existence of steady liquid water on the red planet has been more and more clearly proved ,and the idea that bacterielles fossil was brought to the earth by an aerolite from the Mars was incessantily debated over ,the argument concerning whether this planet witnessed the existence of organism which lives till now will be more fierce.

由于越来越多的证据表明红色行星上曾经含有大量稳定的液态水，由于人们对细菌化石是火星上的一块陨石带到地球上的这种观念争议不休，因此，有关该行星上是否曾经存在生命以及生命是否持续到今天的争论更加激烈。

Since the magnesium metal ions with gas phase state abundantly exist in the aerosphere of the earth and around the other planets, recently, there increasing attentions focused in Mg~+ and complexes related with Mg~+.

由于处于气相状态的金属Mg~+以令人惊讶的丰度存在于地球大气层和其它行星周围，近年来，人们对有关Mg~+及与Mg~+形成复合物的研究给予了越来越多的关注。

It revealed that the gaseous oxygen was related to the deep oxidation of hydrocarbon, since the breakage of C-C bond in allylic intermediate didn＇t exist during the process of reaction. This is due to the weak ability of lattice oxygen to attack hydrocarbon molecular.

实验结果指出，烃类的深度氧化反应与气相氧的存在有关，晶格氧对烃分子中碳碳键的攻击较弱，反应中烯丙基中间体几乎不发生碳碳键的断裂。

Nigra, B. oleracea and B. carinata belonged to class 2A according to the classification of karyotypes by Stebbins (1971). According to Levitzky's and Stebbin's view, the more asymmetric karyotype a species has, the more evolved it is. Therefore, B. campestris is the furthest evolved species among the elementary species, and B. juncea and B. napus the furthest among the amphidiploid species. Compared with the previous reports, there is no any cytoplasm in the chromosome sample prepared using this protocol which is very useful for the karyotype analysis, as well as the FISH research on Brassica species.

对上述研究结果分析表明：（1）芸薹属复合种是由基本种相互杂交而成；（2）B基因组与A或与C基因组亲缘关系较远，而A和C基因组亲缘关系较近；（3）芸薹属复合种在演化过程中，发生了染色体结构上的重排现象；（4）芸薹属复合种演化过程中，rRNA基因位点发生了减少；所获结果与国外同类报道相比表明：国内的白菜型油菜存在新的rRNA基因位点，即rRNA基因在芸薹属同一物种不同的品种间具有多态性；有关这类研究国内尚未见报道。

Our results show that the surface antigen kinetics differences in different patients may be related to different genotypes.

我们的研究表明，不同的患者存在HBsAg动力学方面的差异，可能与患者的不同基因型有关。

Recently, many empirical research in growth use average education level as representative human capital index, and most of us to do so in China, but it is many limitations of education variable, especially it is not measure in currency, so cannot compared with other capital, such as physical capital, in appraisal human capital.

近来，多数有关经济增长的实证研究将劳动者的教育水平作为人力资本的代表性指标，我国大多数学者的研究也仅限于这一方法，但是，基于教育代表指标的研究存在很多缺陷，特别是教育指标大多并非以货币为计量单位，在衡量与评价人力资本作用时，难以与其它资本，比如物质资本进行比较。

For decades we assumed that the reddish regions on Mars are related to the water-rich early history of the planet and that, at least in some areas, water-bearing, heavily oxidized iron minerals are present.

几十年来，我们假定火星上的红色区域和这个星球早期富有水的历史有关，至少在某些地区，含水，存在严重氧化的铁矿物。

For formalized lattice implication algebra theoryT, it is proved thatTis preserved under submodels, unions of chains and homomorphisms;Tis neither complete nor model complete, and hence there exists no built-in Skolem function.

讨论有关格蕴涵代数结构的模型论性质，证明了形式化格蕴涵代数理论T保子模型、保模型链之并、保模型同态，理论T不是完备的、也不是模型完备的，因而不存在内在Skolem函数。

Many legendary theories exist concerning the origin of freemasonry, but it is generally believed that it evolved from the medieval guilds of the stonemasons.

许多传奇的理论存在，有关的原产地，自由，但人们普遍认为它演变从中世纪协会的
