正常人尿中可以偶见的管型是（）

A.红细胞管型

B.白细胞管型

C.上皮细胞管型

D.透明管型

E.蜡样管型

答案

参考答案：D

解析：本题主要考查各种管型的主病，正常人尿中偶然可见透明管型，肾盂肾炎肾实质受感染产生白细胞管型。红细胞管型多见于肾小球疾病；上皮细胞管型提示肾小管有病变；蜡样管型说明肾小管病变严重。

For each blank, choose the best answer from the four choices and write down on the answer sheet.

It is claimed that Al applications have moved from laboratories to the real world. However, conventional von Neumann computers are (66) for Al applications, because they are de- signed mainly for numerical processing. In a larger yon Neumann computer, there is a larger ratio of memory to processing power and consequently it is even less efficient. This (67) remains no matter how fast we make the processor because the length of the computation becomes dominated by the time required to move data between (68) and memory. This is called the yon Neumann (69) . The bigger we build the machines, the worse it gets. The way to solve the problem is to diverse from the traditional architectures and to design special ones for Al applications. In the research of future Al architectures, we can take advantages of many (70) or currently emerging concepts. in computer architecture, such as dataflow computation, stack machines, tagging, pipelining, systolic array, multiprocessing, distributed processing, database machines, and inference machines.

（67）是（）
