中胚层的

Because of its production of raw materials is not all fine flour, but a mixture of wheat flour has been milled down the process of the cortex, germ, aleurone layer and a small amount ...

由于其制作的原料并不全是精面粉，而是混合了小麦在磨粉过程中被碾下来的皮层、胚芽、糊粉层及少量。。。

Binzhou Vocational CollegeAbstract: Using environmental scanning electron microscopy and X-ray electron probe microanalysis, the Pb relative content was studied in cortex, aleuronic layer, scutellum, plumule, hypocoty, radicle and endosperm in 20 genotypes of wheat grains.

从Pb与各元素在不同部位的相关性比较看，Pb与Mg等其它6种元素的相关系数较大的部位均是糊粉层，而胚芽中Pb与其它6种元素的相关系数较低。

Results: Mast cells in uterus were mainly distributed in the myometrium, only a few in the endometrium. After ovum implantation ,the mast cells were comparatively less at the place of implantation. The number of mast cells of early and late pregnancy(1～5 dyas, 15～19 dyas) was apparently higher than that during middle pregnancy(P＜0. 05). Stained by alcian blue-safranin, both red and reddish blue mast cells decreased gradually in number during pregnancy, but the proportion of blue mast cells was increased. Critical electrolyte concentration of mast cells decreased as time went on.

结果：(1)肥大细胞主要分布于子宫肌层，子宫内膜较少，且胚泡植人部位的肥大细胞明显少于非植入部位；(2)妊娠早期(孕1～5d)和妊娠后期(孕15～19d)肥大细胞数显著多于妊娠中期(P＜0.05)；(3)Alcian蓝藏红组化染色后，可见妊娠过程中红色和红蓝混合色肥大细胞逐渐减少；蓝色肥大细胞所占比例逐渐增大，孕9～19d肥大细胞几乎全部为蓝色；(4)肥大细胞临界电解质浓度值随妊娠时间的推移而变小。

GFP fluorescence was visible early at the 2-cell stage and then became stronger in the blastocysts of all three species. However, the distribution of the GFP signals was restricted to the cells of inner cell mass and no fluorescence was detectable in trophectoderm cells.

结果显示：牛Oct-4启动子驱动的GFP基因在3个物种的2-细胞胚胎就已经开始表达，在囊胚期表达加强且只特异表达于内细胞团中，而不表达于滋养层。

Herbicidal active ingredient extracted, isolated and identified from Paulownia tomentosa Steud against Amaranthus retroflexus L., Lactuca sative var.capitata L.

采用活性追踪和柱层析技术，以对杂草反枝苋、生菜、黄瓜种子胚根生长的抑制作用为指标，对泡桐花中除草活性成分进行了提取、分离和鉴定。

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％。
