The intensity and way of the cold high atmospheric pressure center,Ф568 (the latitude at the nodical point of the 5680 geopotential meter line with the 120°E line in the 500hPa high altitude) and Ф850(the latitude at the nodical point of the 0℃ temperature lute with the 120°E line in the 850hPa high altitude) were closely related to the minimum temperature. The equation of short-term forecast of low temperature weather for Fuzhou, Xiamen and Shaowu was established by stepwise regression analysis. The detemperature rate was estimated by cloud cover, wind velocity, humidity (N20, F20, U20) at 20:00 o'clock.

The increased amount of non--exchangeable NH4^＋-N during the incubation indicated as the following tendency, namely, Eum-Orthic Anthrosols 〉 Los - Orthic Entisols 〉 Hap-Ustic Isohumisols 〉 Ust-Sandiic Entisols. Organic material influenced significantly the increased amount of non-exchangeable NH4^＋-N （P was 0.0002, 0.0004 and 0.0003 when incubated at 20 d, 50 d and 60 d, respectively）. NH4^＋-N increased remarkably when Stlpa bungeana and Medicago sativa were added compared with no addition. The contents of non-exchangeable NH4^＋-N increased significantly when added （NH4）2SO4 compared without addition at 20 d, 40 d and 60d of incubation and P was 0.0037, 0.0033 and 0.0027, respectively. It was the result that the NH4^＋-N from （NH4）2 SO4 was fixed within the soil. The increased amount of non-exchangeable NH4^＋-N increased significantly for different soils, on which different vegetation types grew before the collection of soil samples, when incubated at 20 d （P=0.0434）, but not significantly at 40 d and 60d （P=0.7378 and 0.5375）. The increased amount of non-exchangeable NH4^＋-N in the soil, on which crop straw and nitrogen fertilizer had been incorporated for a long-term period, was larger than that of no addition, but it was not significantly different among these two fertilization models. Soil clay, total N and organic matter were positively correlated remarkably with the contents of non-exchangeable NH4^＋-N, the increased amount of non-exchangeable NH4^＋-N had no correlation with soil clay, whereas it had significantly positive correlation with total N and organic matter.

The health risks for a baby born at week 35, she says, are more like those of a baby born at week 30 than one born at week 37."The perception is that a big baby--even if he's premature--is going to act like a term baby. He's not."

Within 24 hours of delivery, 16 breast milk samples from mothers of term and preterm infants were divided into aliquots. Fresh samples were immediately tested for antioxidant activity based on their ability to inhibit the oxidation of 2,29-azino-di-3- to its radical cation compared with Trolox, a strong antioxidant that is a derivative of vitamin E. The remaining aliquots were stored at –20 C or 4 C for analysis at 48 hours and at seven days.

Each of the four men interviewed works at a different specialty on the floor-one is a floor broker, filling orders for the account of other persons or firms; one is an arbitrageur who trades in spreads, seeking profits in the changing relationships between two different but related markets; one is a scalper, a very short-term player who helps provide liquidity on the floor and who rarely takes a position home overnight; and the fourth is a position trader who, by his own admission,"is looking for the big play, in long-term trends."

接受访问的每个人，在营业厅内都有各自不同的专业领域——其中一位是营业厅经纪人，替别人或公司填交单子；一个是套利者，交易的是差价，从两个相关市场间的价格变化中套取利润；一个是做短线的，在非常短的时间内做短线，这种人对营业厅的流动性很有帮助，所做的仓位很少留到明天；第四个是趋势交易者，他自己说，他找的是&长期趋势中赚大钱的买卖&。

Such parameters as the percentage of ordinary reinforcment, amounts and configuration of unbonded prestressed tendons, the ratio of span to depth and the loading patterns were considered. Based on the results, the fomula for the eqivalent length of deformation zone on the beams at ultimate were developed. A simple formula was developed for the ultimate mid-span deflection of concrete beams with concept of equivalent length of deformation zone, and the deformation of beam before internal reinforcement yielding was predicted by the traditional formula for the deformation of partically prestressed concrete beam. Then an analytical model was deduced for analyzing the ultimate stress increment in those concrete beams prestressed with external or internal unbonded tendons based on the mid-span deflection.(4) Testes were carried out on a thin-walled concrete box beam presressed with external CFRP tendons to study its short-term performances under uniform load, long-term behaviors under uniform load, and full-time performance under four-point load in turn.

But at a meeting on Friday, the Atlantic States Marine Fisheries Commission's Horseshoe Crab Management Board again failed to approve a moratorium on horseshoe crab fishing in the key states.
