查询词典 ring

Based on both the strong-weak model and the strong-strong model, the instability caused by ions in equilibrium is simulated, some useful results are obtained. The results include the relation between instability growth rate and neutralization factor, the relation between instability threshold and neutralization factor, and the incoherent tune shift, the tune spread, the ion cloud distribution, the ion loss mechanism, as well as the ion accumulation limitation in the storage ring. With this understanding, we have carried out theoretical and experimental study for some ion clearing methods and their effects for the HLS ring. The minimum static clearing voltage is determined through calculating beam electric field and measuring ion current.

在上述基础上，我们对各种离子清洗的方法及清洗效果进行了理论和实验的研究：通过计算束流电场和测量清洗电极上的离子流来确定直流清洗电极所需的最小清洗电压；通过测量离子引起的频移来计算储存环的中性化系数；用模拟计算和实验测量证实了高频清洗能有效地克服储存环上离子俘获不稳定性；对由高频剔除系统形成的储存环部分束团填充模式下的离子俘获问题进行了初步研究，证实采用束团部分填充模式能在一定范围内克服离子俘获效应；并对各种离子清洗方法进行了比较。

The bearing inner ring and the axis tight fit, the outer ring bearing hole is a more loose with the non-separation-type bearings installed, press the bearings can be installed on the shaft, then shaft with bearings packed together into the bearing hole inside, if the bearing is small, can also be lighter than the soft metal hammer blow set

对无油轴承内圈与轴时紧配合、外圈轴承座孔是较松配合的非分离型轴承进行安装时，可用压力机将轴承先安装在轴上，然后将轴连同轴承一起装到轴承座孔内，若轴承较小时，也可用较软的金属锤轻击套

Based on the-references on the thermal imidization of polyand the polymer composition analysis,the thermal imidization mechanism of SMA with aniline was demonstrated to be a two-stage consecutive reaction,in which a second-order reversible ring-opening reaction of SMA to produce poly(styrene-co-N-phenyl-maleamic acid)and a first-order irreversible intrachain ring-closing reaction to form SNPMI were involved.
