In thistreatment,some embrocyte,which may originate from the nucellus cell,can be foundin few of ovaries in APⅣ.The embryos in most of ovaries in APⅣ and IR36develop normally,but the endosperm,in which many crystal-like substances wereobserved,by spike-spray with 2,4-D 3-hours after pollination.

少数APⅣ子房的"腔"内出现多个"胚状体"，推测可能来自珠心细胞的分裂；在受精后处理的大部分子房胚胎发育正常，但胚乳发育却不正常，胚乳内观察到许多的结晶体。

PFOS induced thyroid follicle cell hyperplasia, the depletion of colloid and even vacuolation with dose-effect relationships after 6 months exposure. Malformations of gonad with intersex, pearling and segmental aplasia were found in all treatment groups. The gonad with intersex showed a testis tissue with a female ovarian cavity like structure.

6个月后，PFOS组甲状腺出现滤泡上皮细胞增生、胶质减少甚至空泡化等现象，且随着PFOS浓度的增加而加重；各组幼蛙性腺出现间性、睾丸珍珠状和先天性萎缩等畸形现象，外观为间性的性腺主要表现为睾丸组织中产生类似雌性个体的卵巢腔。

According to the observation of the microstructure of small diameter lumber with scan electron microscope, there are many bordered pits of the radial trancheidal wall in the small-diameter Larch, and most of them have pit film. The resin is not only in resin canal, but also in some trancheid and ray parenchyma cells. The drying defects of small-diameter Larch lumbers were the most severe in consecution heating, fluctuating-heats 2h in between, and drying defects were nearly not observed in fluctuating-heats 6h. There is tylosis in the vessel of the heartwood of small-diameter Cathay poplar. The bordered pits of the radial trancheidal wall are dense, and the pits between vessels are alternate, most of them have pit film. Different collapse happened in all the small-diameter Cathay poplar lumbers. The collapse of small-diameter Larch lumbers was the most severe with consecution heating, fluctuating-heats 2h in between, the least with fluctuating-heating 6h.

通过扫描电镜观察发现，小径木落叶松的径壁具缘纹孔数目较多，且多具纹孔膜，小径木落叶松除在树脂道中含有树脂外，在一部分管胞胞腔内以及一些木射线细胞中也含有树脂，在产生缺陷的小径木落叶松锯材中，连续加热方式下锯材的开裂缺陷最为严重，波动2时次之，波动6时几乎没有开裂现象；小径木大青杨心材导管中的层状浸填体含量较多，且径壁具缘纹孔较为密集，管间纹孔呈互列方式，绝大多数纹孔具有纹孔膜，干燥后的小径木大青杨锯材均有不同程度的皱缩现象产生，其中连续加热干燥试验锯材的皱缩现象最严重，波动2时次之，波动6时干燥试验锯材的皱缩缺陷最小。

Kaposiform hemangioendothelioma also has slit-like lumina, although they are due to nodules and sheets of compact spindle cells.

Kaposi型血管内皮瘤也有裂隙样腔隙，尽管它们是由于致密的结节状或成片梭形细胞受挤压所致。

Transmission electron microscopy demonstrated that fibroblast was full of endoplasmic reticulums that cisternal-like expanded in the rhEGF nanoparticle group, and collagen proteins were synthesized in cavity.

透射电镜下可见rhEGF纳米微球组成纤维细胞胞质内有大量的内质网，扩张成池状，腔内充满了合成的胶原蛋白。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
