Polymorphism was detected for exon 3 of BMP4 gene in four sheep breeds. For exon 3, three genotypes were detected in four sheep breeds. In Small Tail Han, Chinese Merino, Corriedale and South African Mutton Merino sheep, frequency of genotype AA was 0.017, 0.216, 0.115, 0.429, frequency of genotype AB was 0.102, 0.317, 0.269, 0.500, frequency of genotype BB was 0.881, 0.467, 0.616, 0.071, respectively. Sequencing revealed one singlenucleotide mutation C→A at 305 bp of exon 3 of BMP4 gene in genotype BB in comparison to genotype AA, and this mutation resulted in an amino acid change of alanine→aspartic acid.

对于外显子3的引物，在4个绵羊品种中都检测到3种基因型；统计结果表明：小尾寒羊、中国美利奴绵羊、考力代绵羊、南非肉用美利奴绵羊AA基因型频率分别为0.017、0.216、0.115、0.429，AB基因型频率分别为0.102、0.317、0.269、0.500，BB基因型频率分别为0.881、0.467、0.616、0.071；测序结果表明：BB型和AA型相比在BMP4基因外显子3第305位碱基处发生C→A的突变，该突变导致氨基酸由丙氨酸改变为天冬氨酸；BB型小尾寒羊平均产羔数分别比AB型和AA型多0.61只（P.05）和1.01只（P.05）。

The wave process of sedimentary basin is a form of earth's crust movement,which is controled by both cosmogony and earth evolution.

沉积波动过程是地壳波状运动的具体表现，它是各种天文因素、地质因素共同作用的结果，沉积波动过程的时空演化控制着地层层序的时空展布特点。

The ability of carbon to form stable compounds in such astonishing numbers arises in that it utilizes its four valence electrons completely in the establishment of four covalence,its valence shell becomes saturated.

碳原子能够利用其全部四个价电子构成共价键，并形成稳定的饱和价电子层。这就导致碳元素能构成各类数目惊人的稳定化合物。注意本句使用的是"逆序"的翻译方法。

The group is now covering all production and processing steps from

集团现在已经覆盖所有产品及由原材料处理到终端产品的优化加工步序。

And has selected the most reasonable processing craft, namely: The upper reaches -like tire of the oxygen sludge law and the foreword written comment active sludge law union craft.

并从中选取了最合理的处理工艺，即：上流式厌氧污泥法和序批示活性污泥法结合的工艺。

In this study, critical action research was adopted. Perspectives and theories about installation public art, community empowerment, and cultural reproduction were integrated into the micro society of an elementary school. Results showed that creators could develop their passion for caring the public space and view the champ with empathy during the process. From this activity, the researcher also found potential disorders in the campus champ, which could be a direction of future improvement of art curatorship in campus.

本研究以批判式行动研究法，结合装置公共艺术、社区营造、文化再制理论等观点进入国小微型社会之中，研究结果发现创作者在过程中培养出关注公共空间的热诚，也学会用同理心来看待场域，另外研究者也从活动中发现校园场域的潜在失序问题，可作为日后继续参与校园艺术策展的努力方向。

Two LVRT methods are compared in this dissertation. One is to use VSC valve with larger current capacity, and the other is to use reference current limiter in control system.

对VSC阀在交流电网低电压故障下的过流现象进行分析并提出了一种考虑正负序分量影响的指令电流限制器，保证了故障限流效果。

When short circuit faults occur on one side of a transformer, the sensitivity of current protection on the other side could not be affected.

摘 要：为了避免小电流接地系统中，电流保护的灵敏度受故障类型和相别的影响，提出了一种利用序分量提高电流保护灵敏度的新原理。

The results indicate that wavelet transform is very suitable to the division of cyclic sequences of intermediate order and smaller orders.

划分结果证明小波变换非常适合中期及其以下级别旋回层序的划分。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
