After NMDA stimulation, he concentrations of Ca~2+ and NO in both nuclear and plasma rise observably, especially in the netlike structures; the change of Ca~2+ concentration in nuclear is larger than that in plasma,however the changes of NO concentration in nuclear and plasma are similar. We also observed comparative increases of the concentration of Ca2+ and NO in neurodendrite after NMDA stimulation.

NMDA刺激后神经元细胞核和细胞质内Ca~(2+)和NO都明显升高，尤其在细胞核和细胞质内的网状结构处；细胞核内Ca~(2+)升高幅度大于细胞质，而细胞核内NO的升高幅度却与细胞质相近；另外，树突内的Ca~(2+)和NO升高也较明显。

Firstly, the reaction thermodynamics was analyzed. Then, the reaction mechanism was studied, and the results are as following:① Ca moves to the surface of Dy〓O〓 by vapor phase;② Dy〓O〓 reduced to Dy by Ca is fast;③ Dy moves to the Fe surface mainly by vapor and various Dy-Fe alloys are produced gradually;④ The forming process of DyFe〓 may be described by Contracting Core Model;⑤ The rate-controlling step of the reaction is the Dy diffusing toward contracted and nonreaction nuclear center Fe.

首先考察反应的热力学可能性；其次探讨反应机理；通过实验确定：①Ca主要以气态形式迁移到Dy〓O〓表面参与反应；②Dy〓O〓被Ca还原为Dy的速度很快；③Dy主要以气态形式迁移到Fe表面逐级生成Dy-Fe合金；④DyFe〓的形成过程可以应用收缩核模型来描述；⑤Dy通过DyFe〓产物层向缩小的未反应核中心Fe的扩散是反应的控速步骤，通过动力学计算确定：还原扩散反应的表观活化能E〓=45kJ/mol。

It is probably that there were not Ca〓 channel on the guinea pig sperm PM, because the Ca〓 channel blockers verapamil, nifedipine, diltiazem and D600 promoted acrosome reaction in synchronous and nonsynchronous cultural systems.

豚鼠精子质膜可能无Ca〓通道，因为verapamil、dilliazem和D600等对获能和未获能的精子的顶体反应均具有显著的促进作用。

Spikelets 3–5(–6) mm, dark purple; glumes lanceolate, subequal or lower glume slightly shorter than upper, lower glume 1-veined, upper glume 3-veined, scabrid, apex acuminate; callus hairs ca. 1/3 length of lemma; lemma 3–4.5 mm, papery, hyaline at margins and apex, sometimes scabrid; apex irregularly 4-toothed; awn arising from upper 1/3 of lemma back or above, 1–2.5(–6) mm, straight or slightly curved; palea ca. 2/3 as long as lemma; rachilla conspicuously penicillate, 1.5–2 mm, including hairs up to 5 mm. Anthers 1.4–2.3 mm.

When cellular Ca~(2+) concentration increased, Ca~(2+)与can combinewith calmodin create compound, the latter arose VSMC shrinking through phosphated, and can accelerate express of many cancer gene, such as c-fos、c-myc、c-myb, consequently bring the multiplication and plumped of VSMC.

当细胞内Ca~(2+)浓度升高后，Ca~(2+)与其细胞内受体钙调素(Calmodin，CaM)结合生成复合物，后者通过一系列磷酸化过程引起平滑肌细胞收缩，并可促进多种癌基因的表达，如c-fos、c-myc、c-myb等，从而引起血管平滑肌肌细胞的增殖和肥厚。

Petals yellow; flowers ca. 7 mm; middle outer sepal and apical appendage of keel pocketlike; stems without leaf scars and lenticels; leaf blade membranous, elliptic-lanceolate, ca.

花瓣黄色花约7毫米；中间外部萼片和龙骨瓣顶端附属物口袋状；没有叶痕和皮孔的茎；叶片膜质，椭圆状披针形，约3厘米宽，先端渐尖。

A number of microplants with spherical, triangular, polyangular and boat-like shapes have been found both from the early Palaeoproterozoic Dashiling and Qingshicun Formations (ca. 2500- 2400 Ma) of the Doucun Subgroup of the Hutuo Group and the late Palaeoproterozoic Changzhougou and Chuanlinggou Formations (ca. 1800 -1700 Ma) of the Changcheng Group in North China. According to the features of these fossils, such as size, external shape and internal structure, they may belong to unicellular eucaryotic planktons.

在华北地区古元古代滹沱群豆村亚群的大石岭组、青石村组(约2500～2400 Ma)和长城群的常州沟组、串岭沟组(1800～1700 Ma)中存在着大直径的球形和形态呈三角形、多角形及船形微古植物，根据它们的大小、外部形态和内部结构等综合判别，它们可能属于单细胞真核浮游生物。

The network space is the typical form of abstract space when it comes to the digital stage.

网络空间是抽象空间数字化阶段的典型形式。
