散束

The experimental results show that the increase of the centroid transverse displacement in the beam-pulse flattop duration is confined and the bigger energy-sweep beams are partially rejected in the alternate focusing solenoid field.

实验结果表明，采用交变极性聚焦场聚焦，抑制了束脉冲顶部质心横向运动的发展，同时可剔除束脉冲前后沿能散度较大的那部分束。

The radius of the focal point will gradually rise and the amplitude of the beam wave will reduce as the beam transmits in the channel.

选择适当的系统参数，可调节束聚焦点位置和聚焦点半径的大小，实现电子束的长距传输并且减少电子束的耗散。

When the time for cutting the sheaf had arrived, that is, on the evening of the 15th Nisan, even though it were a Sabbath, just as the sun went down, three men, each with a sickle and basket, set to work.

当时间为削减束已抵达，即是对晚上的十五大尼散，即使它是一个安息日，正如孙下降了，三名男子，每一个镰刀和篮子，设置工作。

The pathological study showed diffuse muscle fiber atrophy predominating in PM and perimysium atrophy in DM.

PM的病理改变主要表现为散在肌纤维萎缩；DM以束周萎缩多见。

At that moment, when you are at the mercy of someone's fingertips, there is nothing that a stargazer or philosopher can teach you, nothing to be gleaned from the hieroglyphics on the inner walls of pyramids.

有时，一束月光穿过冷雨簌簌拍打在窗棂格栅，掸散丝丝蛛网。那是你的心吗？

Methylene blue-basic magenta staining and electron microscopy Regenerating nerve were arranged in bundles in group A and B, there were minifascicle formation and a large amount of proliferated collagen in between the minifascicled, no cicatrices form, regenerating vasa spread randomly, electron microscopy show a large number of myelinated and unmyelinated fiber arranged in buddies.

亚甲基蓝-碱性品红染色及电镜观察两组均见再生神经纤维呈束状分布，有多个神经束，每一个神经束内见大量密集、粗大的有髓神经纤维，神经束之间充满增生的胶原，未见瘫痕形成，再生血管散在分布。

When the stream is collisional, the negative energy nature changes to negative dissipative nature.

流束存在碰撞时，负能性质改变为负耗散性质。

The concept of using this controlled rocking with steel tendons that behave elastically and these energy-dissipating fuses is a general concept that could be applied in different materials and in different forms.

使用这种控制的钢束的弹性地晃动的行为，而这些能量耗散保险丝的概念是一个总的概念可以适用于不同的材料和不同的形式。

The experiment was performed at the Asterix IV iodine laser with a prepulse 5 ns before the main pulse. Under optimum focusing conditions for main pulse and prepulse the X-ray laser beam splits into two beamlets along the target surface at its output end of the 2.5 cm long plasma column. The splitting was still observed when the prepulse alone was defocused.

实验发现在抽运激光主、预脉冲最佳聚焦条件下， X射线激光束在2.5 cm长的线状等离子体输出端沿靶面方向分裂成两束；在抽运预脉冲单独散焦条件下，仍然观察到这一分裂现象；但是当抽运主、预脉冲同时散焦时，这一分裂现象逐渐消失并获得了半宽度只有40 μm的非常窄的近场像。

The accelerator physics problems of the upgrading program were discussed here, which include the space charge effect on the very low energy beam line, non-parity acceleration at the injector cyclotron SFC, longitudinal match between two cyclotrons, strong magnetic field leakage afluence on the beam transfer at low and very low energy, residual first harmonic magnetic field in the main cyclotron SSC injection region, the low efficiency and beam quality of heavy ions after through stripper etc.

主要问题有：超低能束流传输的空间电荷效应的影响，扇聚焦回旋加速器SFC高频加速电压不对称对束流轨道的影响，用半频聚束的方式补偿两台回旋加速器的纵向不匹配，前束线上聚束器的工作模式的选取，强杂散磁场对超低能和低能束流传输的影响，分离扇回旋加速器SSC注入区过垫补磁场对注入束流轨道的影响，SFC和SSC的单圈引出，重离子通过剥离膜后的束流损失和束流品质的变坏等。
