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。

Several antigens of pathogenic microorganisms, such as C subunit of tetanus toxin and the Brucella abortus ribosomal protein L7/L12, were successfully expressed in Lactococcus lactis.

破伤风毒素片段C、布氏杆菌L7／L12蛋白等多种病原微生物抗原已成功在乳酸乳球菌中表达，并已证明部分重组乳酸乳球菌作为黏膜免疫疫苗可以同时刺激局部黏膜免疫应答和系统免疫应答。

Adaptive α-β filter algorithm was introduced, and then it was compared to ISR filter algorithm and Kalman filter algorithm, the mean square deviation of distance, position, speed and direction of these algorithms on the flight line was analyzed to discuss the specific use of the three filters in straight-line flight and about-ship straight-line flight.

介绍了一种改进的α-β滤波算法，然后将它和最小二乘滤波算法、卡尔曼滤波算法进行比较，对三种算法跟踪空中目标的直线飞行、改变航向的直线飞行两种情况的距离、方位、速度和航向等参数的均方差加以分析，证明了改进的。

Many pseudo-scholars have taken out the above story to justify mean acts of conning and treason.

许多伪学者已经采取了上述的故事来证明是指行为的指挥操舵和叛国罪。

With the automatization of degree have improved in the industry, the demand of the mechanism continuity and security also have increased, the reason that cause the operation of mechanism to invalidation is the wear by the friction, which abrade the movement component and joint component.

随着工业自动化程度的提高，对机械零件工作的连续性、安全性要求也提高，而实践证明，导致机械运转失效的主要原因是由于活动构件或者联结件在摩擦力的作用下产生的磨损，磨损导致机械的运转失效，更可能引发安全隐患，这其中磨料磨损占整个磨损总量的50％，故越来越多的研究者对抗磨料磨损的材料进行了一系列的研究。

How to improve corrosionresistance and abrasion resistance is also discussed in this paper.
