内珠孔

The quantities of starch grains in the two"cells"in micropyle part of embryosac gradually decrease and become unclear.With the further development of embryosac the starch grains in the central cell and antipodal cell disappear in succession,however,the egg cell does not.

在准极核移向胚囊中部前后，不同的功能性细胞有不同的表现，珠孔端的两个"细胞"淀粉粒数量逐渐减少并变得不明显，随着胚囊的进一步发育，其中中央细胞和反足细胞内的淀粉粒相继消失，但卵细胞内却一直保存着。

Female flowers: tepals 5 or 6 or several; carpels 2 or 3; ovary superior, 2- or 3-locular; styles 2 or 3, free, persistent; stigma broadly recurved; interstylar nectaries present or lacking; ovules 2 per locule, pendent, anatropous, bitegmic, crassinucellar; micropyle formed by inner integument or by both integuments.

雌花 花被片5或者6或者几个；心皮2或3；子房上位，室2或3；花柱2-3，离生，宿存；宽的柱头下弯；花柱间的蜜腺有或者无；胚珠每室2，下垂，倒生，具双珠被，具厚珠心；珠孔由内珠被或者两层珠被形成。

Synergid cells Two haploid cells located near the egg cell at the micropylar end of the embryo sac in flowering plants.

助细胞：存在于开花植物胚囊内，是位于珠孔端的卵细胞两侧的两个单倍体细胞。

Female flowers: tepals 5 or 6; carpels 3; ovary 3-locular; styles 3, free; stigma often decurrent; interstylar nectaries or nectariferous tissue present; ovules 2 per locule, pendent, anatropous, bitegmic, crassinucellar; micropyle formed by inner integument, rudimentary aril.

雌花 花被片5或者6；心皮3；子房3室；花柱3，离生；柱头经常下延；内花柱蜜腺或分泌蜜汁的组织宿存；胚珠每室2，下垂，倒生，具双珠被，具厚珠心；珠孔形成于内珠被，假种皮不发育。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
