查询词典 dendrite

Our results showed that the total dendrite branch length and arborization of hippocampal neuron were not affected by the inhibition of ASICs for a short time, while the total dendrite branch length was reduced and dendrite development was impaired if ASICs were inhibited for a long time.It suggested that ASICs play a role in the dendrite development,which may help understand how ASICs affect the formation of neuronal networks and participate in higher brain fuctions such as learning and memory.

结果发现短时间抑制ASICs的功能并不影响海马神经元的树突总长度和分支，而长时间抑制ASICs的功能则会降低树突总长度，影响树突的发育，表明ASICs参与调节树突的发育，这将有助于理解酸敏感离子通道如何影响神经网络的形成，并进而参与学习记忆等高级脑功能。

In the present paper, two new hypotheses are proposed that the outward normal of the dendrite surface is parallel to the gradient of the actual supercooling, and that the dendrite growth is capable to minimize the solute transfer .

但是，以往的研究中，枝晶组织和枝晶生长这两个密切相关的问题一直被分隔开来进行研究；在稳态枝晶生长理论研究中，由于枝晶界面真实形状问题没能解决，迄今为止，比较有希望的理论模型都是建立在"枝晶界面的旋转抛物面假设"这样一个早已被认定不是枝晶界面真实形状的"基础"上。

Gscoh gs fsR, gscoh as the solid fraction when the formation of the continuous dendrite framework, fsR as the maximum solid fraction after recalescence,βs as the solidification shrinkage of the primary phase,μas the dynamic viscosity of the liquid, a as the length of L/S coexistence zone,λ2 as the secondary dendrite arm spacing, and tf as the total solidification time. High temperature recovery and recrystallization taking place in these fragments during further cooling results in the further grain size decrease.

本文通过对过冷DD3高温合金再辉过程中累积应力的计算，得到作用于初生枝晶的累积应力σs，可表示为：式中，gl是液相体积分数，gs是固相体积分数，gscoh是连续枝晶网络形成点对应的固相分数，fsR是再辉结束后固相分数，βs是快速凝固中液固收缩率，μ为液态合金的动力学粘度，a是再辉中液固共存区长度，λ2是枝晶二次间距，tf是总凝固时间，即再辉时间。

The mature of pseudo-recalescence is the remelting of dendrites. This leads to apparent refinement of dendrite microstructures. Therefore the experiment support the viewpoint of dendrite remelting for microstructure refinement during supercooling solidification.②Under the condition of supercooling solidification, secondary recalescence cannot show up for single phase solid solution.

伪再辉现象的本质是枝晶熔断所致，由此引起伪再辉试样微观组织被明显细化，从而支持了深过冷凝固过程中组织细化的枝晶熔断说观点；②单相固熔体合金，在深过冷凝固条件下，不可能出现二次再辉。

Experiments show that the formation of tertiary dendrite depends strongly on the alloy type and alloy content. It is hard to form tertiary dendrite for hypoeutectic but easy for hypereutectic.

试验表明，三次枝晶的形成强烈依赖合金类型和合金成分，亚共晶的Pb-Sn合金很难形成三次枝晶，而过共晶的Pb-Sn合金则易于形成三次枝晶。

With the same Fe and Mn content, the primary iron phase in the hypoeutectic alloys is obviously less than that in the eutectic alloys, and α iron phase will form a kind of thin dendrite structure in α-Al dendrite crystal and will have strengthen effect.

在同样的铁锰含量下，亚共晶铝矽合金中的初生铁相明显比共晶合金要少，且α铁相在α铝树枝晶中会形成一种细密的树枝晶结构，可以作为基体的强化相。

Most of such dendrite cores are distributed in the grains with an elliptical morphology; some of them lie in the grain boundaries with triangular or lathy morphologies. There are few dislocations and substructures in the dendrite cores, and there are clear phase boundaries between such dendrite cores and the matrix.

Ni合金过冷熔体中亚稳相和稳定相的竞争形核的计算与实验结果定性吻合，即当熔体过冷度大于某一临界过冷度时亚稳相将作为初生相从过冷熔体中析出，通过分析发现瞬态形核理论能更好的描述深过冷熔体中的竞争形核问题。

The present results showed that both cytoplasm and membrane of neuronal soma and dendrite expressed NKCC1, while KCC2 only expressed in membrane of soma and dendrite. The results also indicated that the dendrites rather than the somata of neurons expressed more NKCC1 in adult rat neocortex, while the level of KCC2 expression in the dendrite membrane was similar to that in the membrane of somata.

结果显示：成年大鼠皮质神经元的胞浆和细胞膜均有NKCC1的表达，而KCC2主要表达在神经元胞体和树突膜上，其中NKCC1在神经元树突上的表达水平比胞体高，而KCC2的表达水平在树突和胞体膜上没有明显差异。

With smaller speed, it refined the dendrite, and, with larger speed, it coarsened the dendrite.

说明流动对枝晶组织有双重作用，流速较小时细化枝晶，流速较大时粗化枝晶。

It was found that boron not only broke up the α-Ti dendrite, but also accelerated Si atoms to spread toward the interface of dendrite of supersaturating β-Ti solid solution and restrained the nucleation and growth of Ti〓Si〓 phases.

研究表明，适量的Al对Ti-Si共晶合金也有很好的强化和韧化作用（σ=1763MPa，ε〓=8.5％）。

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
