当满足这两个条件时，会发生扩宽转换(widening conversion)。例如，要保存所有有效的byte值，int类型总是足够的，所以不需要显式的强制转换语句。

耗费很少的逻辑资源，实现起来简单可靠；还可以减小电路处理时延，提高位宽转换的效率。
At the same time said invention also discloses a method for implementing time-division multiplex circuit bit width conversion.
然而，研究人员并非采用加热整个样本的方案，而是使用了原子力显微镜(afm)一个加热探针去转换出一条仅有12纳米宽的导电带。
However, instead of heating the entire sample, the researchers used a hot atomic force microscope (AFM) tip to convert very narrow ribbons, measuring just 12 nm across, into reduced graphene.
在图中，蓝色的宽箭头表示页面转换，黑色箭头表示卡片调用，而桔红色虚线箭头则表示字段引用。
In the diagram, a thick blue arrow stands for page transition, a black arrow stands for card invocation, and an orange dotted arrow stands for field reference.
