逆向

Some likely reasons for the greater proportion of tuskless Asian elephants compared the African elephants may be due to strong selection in the past by humans killing the tusked male elephants and a gene in Asian elephants which is not as recessive.

与非洲象相比，由于人类过去过分捕杀有长牙的公象。形成非逆向基因淘汰的现象，而造成亚洲雄象无牙的比例较大的原因。

Unfortunately for us reversers, there are quite a few cases where the conditional codes are used in unintuitive ways.

但是对我们逆向工程人员来说很不幸，只有很少一部分条件转移控制是用这样直观的方法实现的。

This idea about reverse engineering your own simple files makes it somewhat easier than trying to reverse engineer a large file with unknown and unmapped

这是关于逆向工程自己的简单文件，使比较容易比试图反向工程大文件与未知的概念映射

These results suggest that the products of the novel gene,mNHX1,on the vacuolar membrane,functions as a Na~/H~ antiporter and may be one of the most important factors determining salt tolerance in mulberry trees .

根据已报道的At-NHX1同源基因的功能推断，mNHX1所编码的细胞液泡膜上Na+/H+逆向运转蛋白是桑树抗盐性能的一个极其重要的因素。

After forward checking, backward checking is carried out to checking the validness of the configurations, which is a reachability analysis.

在正向检查后，使用逆向搜索来检验格局的可达性，设计了一种启发性算法来提高收敛速度。

The dissertation modifies the model of Holdridge's indexes of lifezone according to the features of the ecological climate of Xinjiang. The influence of the variation of vegetation caused by the climate variation of Xinjiang in recent decades is also analyzed. In recent 40 years, the type of life zone hasn't changed, the area and number of patch changed only. The diversity changed but not too much..That is, diversity of life zone changed in little range, the whole entiroment is still be a rather stable state, whill be goo for desertation expand contrandictorily.

根据新疆生态气候特征和生物地理规律对Holdridge生命地带分类模型进行修正，分析新疆近几十年来气候变化所引起的植被变化对于新疆土地荒漠化的影响。40多年来，新疆生命地带的类型数量并没有产生变化，只是各类型的面积和斑块数的变化，多样性有所波动，但是波动不大，也就是说生命地带多样性的震荡幅度不大，整个生态环境处于一种相对稳定的状态，这种稳定的生态环境状态有利于荒漠化的逆向发展； 7。

At the same time, based on the extracted total RNA from the leaves of Zostera marina L., the cDNA clone could be obtained and the Na+/H+ antiporter gene could be studied by applying the techniques of RT-PCR and RACE. Its expression profile could be studied when applying the Northern technique.

同时在所成功提取出的大叶藻叶片组织的总RNA基础上，做出cDNA克隆，再通过RT-PCR和RACE技术等研究方法，来试图探究大叶藻的Na~+/H~+逆向转运蛋白基因，然后可结合Northern技术来研究其表达情况。

Secondly, the genomic DNA is extracted from Zostera marina L. and then amplified by PCR with two oligonucleotide primers synthesized to obtain the partial nucleotide sequences of the Na~+/H~+ antiporter gene. The Na~+/H~+ antiporter gene clone was obtained after a series of manipulation: purificatioin of PCR product, ligation and transformation of recombinant plasmids, blue-white selection and so on. DNA sequence analysis shows that its DNA sequence is highly homologous with the genomic DNA sequence of E.

其次，通过提取大叶藻基因组DNA，根据设计的简并性引物进行PCR扩增，纯化PCR产物，连接，重组质粒转化，蓝白斑筛选等操作，并测序，提交测定序列到NCBI进行BLASTN，结果表明：该序列与大肠杆菌的基因组序列相似性较高，而与其它物种的Na~+/H~+逆向转运蛋白基因没有相似性。

Antiport A membrane transport protein in which the energy liberated by the passive movement of H+ ions across the membrane is coupled to the active transport of another solute, e.g.

逆向转运：物质跨膜运动所需的能量来自膜两侧离子浓度梯度。

In the recent few years, reverse logistics has also aroused more and more interest in china.

近几年来，在中国，逆向物流也引起了越来越多的关注。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
