【单选题】下列有关支气管舒张实验的描述 错误的 是
A.
通常可在FEV1/FVC<70%可选择做舒张试验;
D.
若FEV1较用药前增加≥12%则为支气管舒张试验阳性;
E.
若FEV1用药后较用药前增加≥12%,且绝对值增加≥200ml,则为支气管舒张试验阳性;
【判断题】Dynamic programming is a table-lookup computing method.
【单选题】传感器包括敏感元件、传感元件、( )元件三个功能部件。
【单选题】"Programming", as in "dynamic programming", means:
【单选题】Dynamic Programming can be described as:
A.
A reductionist method because the problem size is reduced in each step until it becomes small enough to be tackled easily
B.
A constructivist method because we work on small problems first and then build up solutions of larger problems
C.
A parallel processing method because we work on multiple parts of the problem simultaneously
D.
None of the options given
【单选题】A pathological situation possible in a Dynamic Programming algorithm is:
A.
The computation time required to come up with the value of a cell in the table can be prohibitively long
B.
The structure of the partial solution table can be too irregular to fit in the computer’s memory
C.
The size of the partial solution table can be too large to fit in the computer’s memory
D.
None of the options given
