后成的

Instead, it folds into itself as the enormous creature matures, creating a rounded rudder called a clavus.

它的尾鳍自出生后就不再生长得更大更长，却折成自身庞大的身躯，形成一个圆舵，也被叫成 calvus。

Cutting reproduction experiments of Codiaeum variegatum were conducted by dipped treatment of Carbendazim and Thiram mixture with different concentrations （300-3 000 mg/L）.

文章摘要：用多菌灵与福美双按有效成分1：1的比例配制成混剂，并稀释成浓度为300～3000mg／L的10种溶液，分别浸泡变叶术插穗后进行扦插试验。

The reaction products between disubstituted phosphinosilane and alkynes were those eliminating SiMe3 after addition rather than those via normal addition.

二取代膦基硅烷和炔类化合物之间的反应不是一般的加成产物，而是加成后SiMe3被H消去的产物。

Majority of aderent cells from BM were fibroblast-like cells, and small parts were endothelioid cells. Aderent cells from PB and CB at the fifth generation contained more endothelioid cells and mononuclear and macrophage-like cells besides fibroblast-like cells.

初始培养和传代培养后，骨髓间充质干细胞多为成纤维样细胞，仅有少量内皮样细胞；而传至第5代的外周血、脐带血间充质干细胞除有成纤维样细胞外，还有较多的内皮样细胞和单核－巨噬样细胞。

To avoid the low yield in direct hydrosilylation addition of allyamine, 1, 1, 1, 3, 3, 3-hexamethyldisilazane is used to protect the amino groups, and the protective groups are removed easily after hydrosilylation addition, then the high yield of ladderlike copolymethyl-aminpropylsilsesquioxane was obtained.

为了克服将烯丙基胺直接与聚氢基甲基倍半硅氧烷进行硅氢加成反应接枝效率低的缺点，探索用六甲基二硅氮烷对烯丙基胺预保护，硅氢加成反应后再脱保护，从而以较高产率制备了含胺丙基、甲基的反应性梯形共聚倍半硅氧烷。

Results In define induction envioroment, HPMSCS can diferentiate into lipoblast、after 2 weeks, the induced cells are full of lipid droplet;HPMSCS can differentiate into osteoblasts, after 4 weeks, we can see calcified tubercle in the cells, calcium in the calcified tubercle can be dyed black by Von Kossa and ALP dying is positive reaction above 95%.

结果 HPMSCS在培养基中持续培养后，在特定诱导环境下，成功使其向成脂肪细胞转化，培养2周时，可见融合成团的脂滴充满整个细胞；成功使其向成骨细胞转化，培养4周以上可见明显钙化结节，von Kossa染色可将骨结节中沉积的钙染成黑色，碱性磷酸酶染色呈强阳性反应达到95%以上。

Methods: The fibroblasts companying human hepatoma were primarily cultured with explant culture method, first passaged after they spread to the bottom of the culture bottle, and pured by enzyme digestion and repeated strapping the cells were identificated through observing the morphologic change using invert microscope and detecting expression of vimentin, keratin by iMmunohistochemical method.

应用组织块培养法进行人肝癌伴生成纤维细胞的原代培养，细胞铺满培养瓶底后首次传代，通过胰酶消化法和反复贴壁法进行成纤维细胞的纯化；通过倒置显微镜观察细胞形态、免疫组织化学方法检测细胞膜波形蛋白、角蛋白表达情况，对细胞进行鉴定。

The results were:① The number of pCREB immunoreactive neuclei and total amount of pCREB in the subnuclei of rat amygdala, Dentate gyrus and Cornu Ammonis 3(CA3) were increased after FS.

在DG颗粒细胞层内，对照组的pCREB阳性细胞核数目很少，成线状散在分布；而FS后pCREB阳性细胞核的数目明显增多，成带状密布于整个DG颗粒细胞层。

The sensitivity of the stdA-specific primer set was demonstrated on a Salmonella-free swab sample from a pork carcass surface, which was then artificially contaminated with different concentrations of S. Typhimurium. Inoculation studies showed that stdA-specific primer set detected Salmonella in samples having initial 4.4 × 100 CFU/ml of Salmonella inoculum prior to the enrichment step in the presence of 4 × 107 CFU/ml of non-Salmonella florae.

并且进行接种试验，屠体液中非沙门氏菌细菌数量为4× 107 CFU/ml，当4.4 × 100 CFU/ml的沙门氏菌加上屠体液於培养液中增殖后，可以使用stdA成对引子藉由PCR方式看到stdA的产物，表示stdA成对引子在PCR反应液中存在沙门氏菌及其他菌种时，仍然可以顺利进行反应，而不会受到影响。

At the end of Mingshui Formation, hydrocarbon generated by Qingshankou source rocks migrates down along open boundary faults of concentrated ribbons at the force of overpressure,then short lateral-migration along channel sand, finally accumulated on horsts and fault terraces of the uplifted side of both sides,but in the intensive fault zone,most of the units are grabens,so it is not good for accumulation.

明水组末期青山口组源岩生成的油气在超压作用下，沿开启的断层密集带边界断层幕式下排后通过河道砂体短距离侧向运移，在两侧上升盘地垒或断阶圈闭中聚集成藏；而断层密集带内多为地堑式组合，不利于油气聚集；在成藏模式指导下刻画出47个油气富集目标区，预测石油地质储量0.5 亿t。
