The number of restrikes can be decreased significantly by using a bipolar load current arc conditioning.

只有通过两个极性负载电流的电弧老炼才能有效地减少真空开关的弧后延时重击穿现象。

The first Chinese atomic device, which had been tested the month before on October 16, had a yield of 22 kilotons and weighed 1,550 kg, far too heavy for the DF-2A (when the 200 kg reentry vehicle aeroshell had been added). On December 13, the Defense Science and Technology Commission, which oversaw both the missile and nuclear bomb programs, demanded the reduction of the weight and size of the first operational atomic bomb in order to fit it on the DF-2 A.

中国人的首个核装置于一个月前，即10月16日进行了爆炸试验，2.2万吨的当量，重1，550公斤，远远超过东风2A的负载能力（考虑到还要加上200公斤的再入段弹头载具）。10月13日，负责监督导弹与核弹两个项目的国防科工委要求减少首个作战用核弹的重量和尺寸以便使其能够装入到东风2A上。1965年11月，两弹合一的导弹成功进行了飞行试验，但核弹头此时仍未完成改进。

The method comprises: when mobile station initiates a joint attach request or a route area/location area renewing request, if the MSC/VLR selected by the serving SGSN needs to be transferred to other MSC/VLR due to heavy load or reset, it returns a location renew acceptance message carrying virtual NRI to the serving SGSN; the according to the NRI carried in the location renew acceptance message, the serving SGSN decides if the MS needs to be transferred to other MSC/VLR; the serving SGSN reselects the serving MSC/VLR in node pool, and re-initiates a location renewing request to transfer the MS to other MSC/VLR.

当移动站发起联合附着或路由区/位置区更新请求时，若服务SGSN选择的MSC/VLR因负载过重或重启等原因需要将MS转移到其他MSC/VLR，则向服务SGSN返回携带虚拟NRI的位置更新接受消息；服务SGSN根据接收的位置更新接受消息中携带的虚拟NRI判断需要转移MS到其他MSC/VLR，服务SGSN在节点池中重新选择服务MSC/VLR，重新发起位置更新请求，将MS平滑地转移到其他MSC/VLR进行附着或位置区更新流程。

Firstly, phenyliodine diacetate was immobilized to the 2% cross-linked polystyrene or the liner polystyrene resin. The more iodine the resin had, the lower conversion to phenyliodine diacetate. We made our endeavor to extend the range of useful application of polystyrene supported phenyliodine diacetate in organic synthesis:(1) the reagent was used as an effective reagent of carbonyl regeneration from oximes and semicarbazones of ketones.(2) the reagent was also applied to the synthesis of 1, 3, 4-oxadiazoles, 1, 3-disubstituted-2-pyrazoline, 2-arylbenzoxazole from aldehyde N-acylhydrazones, aldehyde hydoazones and phenolic Schiff's bases respectively.
