The results indicated that the Spisula solidissi ma could reach sexual mature in one year and spawned just one time in one bree ding season.

结果表明，大西洋浪蛤一年能达到性成熟，一个繁殖季节产卵一次，卵为球形，卵径为 50～60μ m；在23℃左右水温下，受精卵经16～20h发育成D形幼虫，幼虫浮游期为16～20d；壳长260～290μ m时为附着变态阶段。

It is, he says,"a document of the tribute system of the empire", with pieces of turquoise from mines that were over 1,000 miles apart, white teeth carved from shells found on both coasts of Mexico, and red details made out of Spondylus, a thorny oyster shell found 60 metres below the surface of the sea.

MacGrego说，双头蛇是&皇朝祭祀的证明&，它身上的绿松石来自与地下1000米的矿藏，白色的牙齿用墨西哥两岸的贝壳雕刻而成，红色的尾巴取自于海菊哈，这是一种在海面下60米才能找到的带刺哈利壳。

The charcoal of rice straw was composed of irregular slices and could be compacted tightly. Rice hull charcoal was full of strumae,which was hard to compact,and probably it was the main reason for the higher electrical resistivity.

cm。在 900。℃以上时，焦炭微观结构与温度关系不大，而随秸秆种类不同而差异较大；稻秆焦炭外表面为层叠的不规则薄片；稻壳焦炭外表面为规律排列的瘤状凸起结构，这使得其在一定压力下难以紧密压实，增大了体积电阻率。

Based on seed-emulsion polymerization, the stable silicon-acralyte core/shell latex with little coagulum were synthesized at lower temperature with potassuim persulphate, sodium formaldehyde sulfoxylate and V-044 as composite initiators.

选用过硫酸钾、甲醛合次亚硫酸氢钠和2， 2'-偶氮二[2-（2-咪唑啉－2-代）丙烷]二氢氯化物(V-O44)为复合引发剂，在低温下通过种子乳液聚合技术合成了生成凝聚物少的硅－丙核／壳乳液。

The varying of expression of Cfos in different phases and different brain tissue including caudate nucleus, putamen, globus pallidus, hippocampus, nuclei ventrolaterales thalami, parvocellular reticular nucleus, and dorso lateral magnocellular nucleus were examined by immunohistochemical technique.

采用Cfos免疫组化染色，在显微镜下观察Cfos于不同时相在脑膜、脑皮质区及相关核团如尾壳核、苍白球、海马、背侧丘脑腹后外侧核、小细胞网状核、背侧旁巨细胞核的阳性细胞数。

Methods The epithelial cells, which were taken from neonate Wistar rat, were cultured into tubiform epithelium together with the frame of shell polysaccharide matrix in vitro.

用Wistar大鼠乳鼠皮肤为细胞来源，结合管状壳多糖基质网架，在体外共同培养成复层皮肤结构，移植到裸鼠皮下。分别于移植的5、7、14、28、35 d收取标本，光镜下观察移植物生长情况。

Effects of appending auxiliary agents on MP Typha latifolia L preservation with chitosans were investigated at normal temperature (20～25℃).

研究了室温下(20～25℃)添加氯化钙和VC等助剂的壳聚糖对鲜切蒲菜涂膜保鲜效果。

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。
