Examples
- On - off keying ook
通断键控 - On - off keying
通断键控 - A hydrogen and argon ions mixing beam was implanted into the deposited vanadium oxide film . after annealing , vo2 film with tcr ( temperature coefficient of resistance ) as high as 4 % was obtained . the bombardment of ar + could break v - o bond of v2o5 molecule in deposited film and implanted h + resulting in the deoxidization of v2o5 , so the vo2 thin film could be prepared by proper control of the dose of ar + / h + implantation
利用离子束增强沉积设备，在ar ~ +离子束对v _ 2o _ 5靶溅射沉积的同时，用氩、氢混合束对沉积膜作高剂量的离子束轰击，使得被氩离子轰击后断键的氧化钒分子，再被注入氢降价，然后经适当的退火，成功地制备了热电阻温度系数高达4的vo _ 2薄膜(国外报道值为2 - 3 ) ，并研制了单元悬空结构探测器和8 1 ， 16 1线性阵列。 - Ultrafine a - ahoa powder with average crystalline size of 27nm and spherical secondary partical shape of 40nm has been prepared by the method of adding dispersant before reaction . after discussing the agglomeration mechanism , the paper studies the way to eliminate the hard agglomeration . it thinks that main reasons to lead to agglomeration are larger specific surface area and high reactivity of nanopowder
认为导致团聚的主要原因是：纳米粉体颗粒的表面有许多断键，相互之间或与其它物质之间容易产生毛细管力、氢键、化学键等多种作用力，在采取措施消除团聚的过程中必须全方位考虑，实现全程控制。
