Although CMOS technology offers low cost alternative, they suffer major problems such as large size in output transistors, stability issues on driving low resistive in parallel with high capacitive load at high bandwidth, noise and so forth. 虽然CMOS技术具有低成本的优点,但是较大的输出管尺寸,驱动低阻抗负载时稳定性问题,驱动高容性负载时带宽问题以及噪声干扰等一直限制了CMOS应用技术的前进步伐。
Officials in the coastal Peruvian province of Callao on Monday hailed the Guinea pig as a low cost, low fat alternative to a traditional turkey or roast pork Christmas dinner. 秘鲁的沿海省份卡里奥的官员在周一宣布天竺鼠可以摆上圣诞餐桌来代替传统的火鸡或是烤猪。天竺鼠更加的便宜,而且脂肪含量较低。
Piezoelectric materials possess high degree of high power density, greater efficiency and potential for low cost manufacture in comparison with alternative electromechanically coupled materials. 与其它相应的力&电耦合材料相比,压电材料不但具有造价较低的特点,而且压电材料好具有更高的能量密度、更高的效能和更广阔的发展空间。
The whole separation was achieved in less than 10 min. The simpler sample pretreatment and relatively low running cost make CZE good alternative to existing methods. 整个电泳分离过程在十分钟内完成。本文的方法因其简单的样品处理过程和相对低的运行费用,为唾液中这些离子的测定提供了一种可供选择的方法。
However in view of the very low cost of PIOs, this can be indeed a very inexpensive alternative. 然而由于PIO价格低廉,故这种方法是非常经济的。
