The current scheduler can only be executed by one processor at a time, which makes it a severe bottleneck, depending on the type of system load. 在同一时刻内，调度程序只能运行在一个处理器上，随着系统的负载量增大，这产生了严重的瓶颈。
The major advantages of these reactions are excellent uniformity, large load size, and ability to accommodate large diameter wafers. 这种反应器的主要优点是优越的均匀性，较大的负载量及适应大直径基片的能力。
