Methods Monoclonal antibody against the glycophorin A was used to identify nucleated erythrocytes in the peripheral blood of pregnant women.Candidates fetal cells from 3 pregnancies at 16 to 24 weeks of gestation were isolated successfully.Sorted cells were also confirmed using Y-special probe (PY3.4) repeated sequences in maternal blood from women carrying male fetuses were detected by polymerase chain reaction.Results The PY3.4 position hybridization rates were 31.5%0 and 38% respectively in sorted GPA positive cells of 3 samples by FISHand the results of GPA+ cells of the 3 cases by PCR were positivenegative and positive respectivelywhich were manifested by the gender after aborticide.

选用红细胞特异单克隆抗体Glycophorin A结合流式细胞术成功地从3例妊娠16～24周的孕妇血中分离出NRBCs，并用Y-染色体特异重复序列DNA探针(PY3.4)荧光原位杂交及聚合酶链反应技术检测Y-染色体特异序列结果 FISH结果，3例分选出的GPA阳性细胞中PY3.4杂交阳性率分别是31.4%、0、38%；其PCR结果，分别为阳性、阴性、阳性，并在引产后得到性别证明。

A method of target detection in infrared image sequences is proposed based on the least absolute deviation background predication.

本文提出了一种基于最小一乘背景预测的红外小目标检测算法。

Thus, a method of weak and small target detection in infrared image sequences is proposed based on the least absolute deviation background prediction and the genetic algorithm.

因此提出了基于最小一乘估计和遗传算法进行背景预测的红外弱小目标检测方法。

Sequences of 28S rDNA across Acari, though with variable region, were not randomly distributed, with the expansion segments being more variable than the core regions and with an increasing sequence divergence with taxonomic distances.

散布图显示，转换取代与颠换取代有类似的线性变化；支序分析及群聚分析的亲缘关系显示，同科及同属内的成员都群聚的很好，全爪蟎属与小爪蟎属的亲缘关系近，与叶蟎属较近的是岩蟎属。28S rDNA的序列特性显示，其核心序列适合分析较高阶的蟎蜱亲缘，而展延区则可应用於低阶的分析。

In this study,~3000 bp of 28S rDNA sequences from nine tetranychids, two tenuipalpids and two acarid mites were used to probe the essence of this gene and its applicability to the delineation of phylogenetic relationship of these species.

本文分析9种叶蟎、2种拟叶蟎及2种根蟎28S rDNA约3000个核苷酸的序列特性，并评估此基因在蟎蜱高阶亲缘关系的应用。28S rDNA序列在蟎蜱的变异并不是逢机的，其核心区段变异较其两侧的展延区小，且分类关系离越远其序列差异就越大。

These sequences have been submitted to GenBank with Accession number EF554399, EF554400, EF554400, EF554401, respectively.

将这些序列提交GenBank分别获得登陆号为：EF554399，EF554400，EF554400，EF554401。

本文报道的氨肽酶cDNA序列已提交GenBank，AY346383和AY279535分别是Bt抗性和敏感品系的Haapn2。

So I have to spend time thinking about the action sequences, about which shot can help the action sequence be more exciting. It's been a lot of work for me.

所以，我需要花些时间想想一连串的动作设计，如何可以令这些动作更加刺激，这让我有很多工作呢。

Crew members made a model of the set according the requirements in the script. The director and I discussed the details of the script while examining the model of the set; how things should be done and how the action sequences should be shot etc. We exchanged many ideas and it was extremely constructive.

工作人员根据剧本的要求做了一个场景的模型，我和导演看着模型在研究剧本的细节，应该怎样做，动作又怎样等等，交流了很多意见，非常有建设性。
