形态发生

The chemical characteristics were obtained when silicic acid existed in the iron hydrolyzed solution.

实验结果表明：硅酸的存在使Fe水解溶液的pH弛豫特征产生了一定的改变，表现出低OH/Fe摩尔比时的阻聚效应和高OH/Fe摩尔比时初期的促聚效应，并使Fe在溶液中的形态分布及转化特征发生了一定的改变。

And the percents of apoptosis and necrosis increased. The morphology and microstructure of SiHa cells changed significantly after treated with 20 μmol/L β-sitosterol.

与对照组比较，20μmol/L的β-谷甾醇使SiHa细胞出现S期聚集、凋亡和坏死细胞增加，细胞形态和超微结构发生显著改变。

From the modeling results,following conclusions are drawn:(1) By trimming the reactor channel walls into streamlined shape,the recirculation cells can be minimized so that the smoot...

对于优化后的反应器，发生对流涡旋的临界高度提高到2~2.5 cm，对应的反应器直径增加到40 cm；(3)在相同温差、不同衬底温度的条件下，反应器内的流动形态不同。

Under such a solidification condition that the growth rate is low and the temperature gradient ahead of the solidi fication front is steep, a large amount of α-Al nuclei can be produced by peritectic reaction, during which only metastable Al〓Zr particles or very fine equilibrium Al〓Zr particles rather than larger equilibrium Al〓Zr partiles are involved.

在低的生长速度和高的界面前沿温度梯度条件下，结晶前沿Al〓Zr粒子与液态铝发生包晶反应（只涉及亚稳Al〓Zr或尺寸极小的平衡Al〓Zr，而不涉及尺寸较大的平衡Al〓Zr）产生大量α晶胚，α晶胚呈球面生长，最终形成等轴非枝晶形态。

According to these, not only copper but also cadmium had chemical specie transformation during the occurrence and development of cancer.

由此提示了不仅铜，而且镉在癌症的产生与发展中发生了化学形态的变化。

Spermiogenesis is a crucial process for germ cell formation, which ensures the efficient transmission of the paternal genome by the spermatozoa to the ooctyte at fertilization.

它包括染色质的压缩、顶体和鞭毛的形成以及去除多余的细胞质，是精子发生的一个重要环节，确保了成熟精子具有正确的形态和完整的功能。

To screen resistant rice varieties in Liaohe Valley to the rice stem borer Chilo suppressalis Walker, development of and damage by the borer larvae on the varieties were examined using intact-plant resistance evaluation method, and morphological and biochemical characteristics and number of silica cells of the rice varieties were determined to explore the potential resistance mechanisms.

采用活体成株鉴定法测定了辽河流域主栽水稻品种对二化螟发育和为害的影响，同时测定了不同品种的主要形态特性、硅细胞数量和主要生化特性，评价这些品种对二化螟的抗性、分析其发生的可能机制。

Results The hela cells which transfected with HSV-TK and IL-12 gene was obviously changed in appearance after 24 hours which added GCV, but the normal control cells growthed prosperity. The survival rate of the hela cells which transfected with HSV-TK and IL-12 gene was fall-off with the plus of tile GCV. The killing effect of GCV for the hela cells transfected with HSV-TK and IL-12 gene was more strengthener than that for the normal cells.

结果 加入GCV后体外培养联合基因转染的Hela细胞，24h后细胞明显发生形态上改变，正常对照组细胞生长旺盛；随着GCV剂量的加大，转染联合基因的Hela细胞的存活率呈逐渐下降的趋势，GCV对转染细胞的杀伤作用较对正常细胞的杀伤作用明显增强。

The result of regression analysis shows that urban land expansion mostly locates in the strip area near the Songhua River, and the urban form appears as a strip city in shape.

回归分析结果表明，城市用地扩展主要发生在距离松花江较近的带状区域内，城市总体形态为带状城市。

Seasonal alternation of the dominant and the subdominant winds reduce migrating rate and keep the height of the primary ridges, and maintain a certain extent and position of the secondary ridges on windward slope of the primary ridges.

沙丘形态与区域气流相互作用产生的沙丘表面气流在迎风坡向丘顶加速使丘顶输沙率成倍增加和沙物质运动加强，且其程度随原始风入射角和坡形系数而发生变化。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
