Low concentration ryanodine can mimic BDNF to induce growth cone attraction and high dose ryanodine gradient is repulsive to the growth cone.

ryanodine 可以模拟 BDNF 的吸引作用。为进一步研究 Rho GTPases 在轴突转向中的作用，我们将 Cdc42及 RhoA 的显性失活突变基因(dominant negative， DN)及组成性激活突变基因（ constitutively active， CA ）注射到爪蟾胚胎2-4细胞期的一个细胞中，使它们在胚胎神经元中表达，并观察这些突变基因对 BDNF ， LPA ， ryonodine 诱导的轴突转向的不同影响，从而推测 Rho GTPases 是否直接参与并介导轴突导向。

A APDL program is developed for analyzing the contact stress of journal bearing pair of roller cone bit. The 25 contact stress cases of different clearance fit(including clearance of large bearing is bigger, equal to and smaller than that of small bearing) journal bearing pair of the 8 1/2XXX roller cone bit are analyzed. The result is that the maximum contact stress is less when the clearance of large journal bearing pair is smaller than or equal to that of small journal bearing pair.

用参数化设计语言APDL编制了牙轮钻头滑动轴承的ANSYS接触有限元分析程序，根据钻头制造厂方提供的某8 1/2的轴承配合间隙尺寸，分三种不同的间隙配合（大轴间隙大于小轴间隙、大轴间隙等于小轴间隙、大轴间隙小于小轴间隙），共25种情况，对轴承的表面的接触应力进行了分析，得出：大轴间隙小于等于小轴间隙时最大应力比较小。
