一段英译汉
In many physiological processes within cells,Ca2+ plays an essential role in controlling cellular
behavior and functioning in the sense that calcium ions act as a signalling agent for a wide range
of cellular activities.Calcium signaling is mediated through oscillation in intracellular Ca2+ concentration.
Calcium ions can bind to a vast number of proteins and enzymes,and the binding can
initiate a series of reactions that ends in the formation of a chemical called inositol 1,4,5-trisphosphate
(IP3).The diffusion of Ca2+ and IP3 through the cell cytosol can induce further release of
calcium ions from stores in the endoplasmic reticulum (ER) through IP3-sensitive channels.These
channels are sensitive to calcium itself,with fast activation for lower concentrations and comparatively
slower inhibition,thus leading to the calcium-induced calcium release (CICR).Complex

wave characteristics such as plane waves and spiral waves have been observed in experimental
studies using Xenopus oocytes as pointed out by McKenzie and Sneyd [19].However,the detail
mechanisms underlying these oscillation and waves are only partially understood

In many physiological processes within cells,Ca2+ plays an essential role in controlling cellular behavior and functioning in the sense that calcium ions act as a signalling agent for a wide range of cellular activities.
钙离子在很多细胞活动中充当了信号剂的作用,因此从这种意义上讲,在很多细胞内的生理学过程中,Ca2+ 在控制细胞行为和功能方面起到了重要的作用.
Calcium signaling is mediated through oscillation in intracellular Ca2+ concentration.
钙的信号作用是通过细胞间 Ca2+ 浓度的震荡变化来实现的.
Calcium ions can bind to a vast number of proteins and enzymes,and the binding can
initiate a series of reactions that ends in the formation of a chemical called inositol 1,4,5-trisphosphate (IP3).
钙离子可以与很多蛋白质和酶相结合,这种结合可以引起一些列的反应,最终 形成我们叫做三磷酸肌醇（IP3）的一种化学物质.
The diffusion of Ca2+ and IP3 through the cell cytosol can induce further release of
calcium ions from stores in the endoplasmic reticulum (ER) through IP3-sensitive channels.
Ca2+ 和 IP3 在细胞质中的扩散可能会导致通过 IP3 敏感通道进一步释放内质网中储存的钙离子.
These channels are sensitive to calcium itself,with fast activation for lower concentrations and comparatively slower inhibition,thus leading to the calcium-induced calcium release (CICR).
这些通道对钙本身敏感,通过对较低浓度和较低抑制作用的快速活化,以此实现“钙诱导钙释放”（CICR）
