Under imitated daily field microclimatic conditions for heat stress, the rice cultivar "Jinyou63"(which is a hybrid rice combination) was treated with a consecutive 3-day heat stress during meiosis in phytotron. Anther and pollen tissues at different development stages after subjected to heat stress were sampled and analyzed for transverse abnormalities.

We selected the 2nd and the 3rd generation yeast with powerful vitality from the yeast mud fermented in tanks in working field as the ideal species source separated from yeast monoplast in beer and the ways to obtain them were as follows: 24 hours after deoxidisation of diacetyl to threshold value and decrease of its temperature to 5℃ was the best time for selection and sample－extraction location was at the nozzle of pressure－discharge pipes.

摘 要：从生产现场大罐发酵的酵母泥中选取第2～3代生命力强的酵母作为啤酒酵母单细胞分离的理想种源，选取的最好时间为双乙酰还原至阈值后降温至5℃，并让其停留24h时取样位置为排压酵母的管口，最后将所得菌种进行初选、复选或模拟生产恒温培养鉴定，选出优良菌株。

The annual rate of people who had ischemic strokes in Nueces County appears to be lower than the national average—approximately 0.1 percent versus approximately 0.2 percent—but Morgenstern says his study did not compare stroke incidence in Nueces County to that of the U.S.

研究中取样的Nueces县缺血性中风患者占总人群的比例为0.1%，低于全国的0.2%，但Morgenstern说他在研究中并没有将两者进行比较）。
