据权威性的报道,去年由于无线系统和嵌入系统市场蓬勃发展,许多关键的电子元器件缺货,交货也受影响。也许,这并没有多少新闻价值,但它提醒人们,按照惯例,对整机产品的需求周期与元器件供应周期并不合拍,时间也不同,所以这个供需关系有时会超前,有时会滞后。最新的微处理器或高密度存储器集成电路等等高级的器件,常常会出现短缺,因而价格上扬,或者由厂商分配供货。更不寻常的是,不仅仅是高级的集成电路如今出现短缺,像二极管和 According to authoritative reports, due to the booming wireless system and embedded systems market last year, many key electronic components were out of stock and deliveries were also affected. Perhaps, this does not have much newsworthy, but it reminds people that according to the usual demand cycle of the whole product and parts supply cycle is not in the same time and different, so the supply and demand sometimes lead, and sometimes lag. Advanced devices, such as the latest microprocessors or high-density memory integrated circuits, are often short-circuited, so the price goes up, or they can be allocated by vendors. Even more unusual, not only are high-level integrated circuits now in short supply, like diodes and
