查询词典 sieve

The results are as follows:Defatted wheat germ was micronized useing both hammer mill and colloid mill to increase the extraction rate of protein, followed by alkali extraction and ultrafiltration, respectively. A quadratic mathematical model was statistically constructed by using of Box-Behnken central composite design and response surface methodology. Under the optimized processing parameters of 23μm particle sizes, pH 9.5 and 51℃, a maximum extraction rate, 68.6%, was achieved, which is 30.63% higher than that of non- micronized wheat germ (passing through 80 mesh sieve).

For if a question is absurd in itself and calls for an answer where none is required, it not only brings shame on the propounder of the question, but may betray an incautious listener into absurd answers, thus presenting, as the ancients said, the B83 ludicrous spectacle of one man milking a he-goat and the other holding a sieve underneath.

因为如果一个问题本身是悖理的，而要求的答案又是无所谓的，这样的问题就不但是提问者的耻辱，而且可以使不注意听话的人陷入悖理的解答里去；从而呈现出一种可笑的光景，像古人所说的那样，一个人在挤公羊的乳，另一个人拿着筛子去接。
