过筛

Then is is better for you that you cover your nakedness and pass out of love's threshing-floor

那不如掩盖你的裸露，而躲过爱的筛打

MATERIALS AND METHODS: Arg to Ser mutation was introduced into the 249 position of the p53 gene by knock-in method. These ES cells with this mutation were selected according to the homologues-recombination with PCR and Southern blot. The positive ES cells without a selection marker were injected into blastocysts recovered from Hprt(superscript -/-) mice, which were derived from Hprt-deficient ES cells. The injected blastocysts then were implanted into pseudopregnant females.

材料与方法：利用基因打靶技术在小鼠胚胎干细胞p53基因249编码子中引入点突变，使编码子249由精氨酸变成丝氨酸，然后将含突变的ES细胞显微注射到Hprt小鼠囊胚中，将注射过的囊胚植入假孕的雌性小鼠子宫，到第14d取小鼠胚胎纤维母细胞，用含HAT的培养液筛选出从ES细胞分化而成的鼠EF细胞，经测序证实细胞含有由249Arg到Ser的突变。

Add two cups of sifted flour to one cup of sugar and mix.

The invention provides a sulfur oriented adsorption control method for calcining active lime in a rotary kiln comprising the following steps: the rotary kiln calcines the massive limestone using the mixture of the coal fines and active lime fine silts as fuels, the sulfur in the flue gas is adsorbed using the sulfur adsorption and desulphurizing ability of the active lime fine silts, meanwhile the sulfur-adsorbed kiln dust is separated from the calcined active lime by means of screening to get low sulfur-content active lime.

本发明提供的回转窑煅烧活性石灰中的硫定向吸附控制方法，具体是：回转窑以煤粉与活性石灰微细粉粒的混合物为燃料，在对块状石灰石煅烧时，利用活性石灰微细颗粒所具有的硫吸附与脱硫能力对烟气中的硫进行吸附，同时通过筛分将吸附了硫的窑灰与煅烧过的活性石灰分离，而得到低硫含量的活性石灰。

Clifford had had it newly gravelled with sifted gravel from the pit-bank.

婉蜒地横过大花园直至树林门口。克利福新近才叫人在这小路上铺了一层从煤坑边取来的筛过的沙砾。

Methods Soil was air-dried, grinded, and screened through 100 mesh sieve. Appropriate sample was put in porcelain crucible with 0.5 g Aldrin reagents, and another 2 g Aldrin was used to cover the sample. Then the mixture was burned, cooled off, lixiviated by water, and determined by arsenic-cerium redox spectrophotometry.
