Although hasten of near future of upriver cooking benzene is firm, but the range that the market rises is not big, each manufacturer is maintained more move smoothly, the amplitude modulation on shipment price is lesser, to suitable anhydride market prop up gradually firm, if crude benzole market goes high further, driving the possibility that cooking benzene rises is not to do not have, the crude benzole stock of manufacturer of each cooking benzene and benzene hydrogenation manufacturer is not at present much, the crop of cooking benzene is not big, market supply of goods is not much, do not eliminate small to walk along high probability.

虽然上游焦化苯近期趋稳，但市场上涨的幅度不大，各厂家多维持平稳运行，出货价格上调幅度较小，对偏苯三酸酐市场的支撑渐稳，若粗苯市场进一步走高，推动焦化苯上涨的可能性不是没有，目前各焦化苯厂家和苯加氢厂家的粗苯库存并不多，焦化苯的产量不大，市场货源不多，不排除小幅走高的可能。

According to ZHUANG 52 block developing character, studying the reservoir remaining oil distribution, finding out a set of technique to excavate the complex block reservoir and offer a good reference to improve the developing effect of maturing oilfield in high water-cut and output decline stage.

In the whole growth period of spring wheat, the response was different in yield and phase growing on climate change, such as the appearing time of sprouting, jointing, tasselling and maturity being ahead but milking being postponed. That is to say, it shortened the spring wheat's nutrition growth stage of seeding-sprouting, elongated the sprouting-jointing stage, cut down the generative growth in the jointing-tasselling phase, prolonged the tasselling-milking stage, and shortened the milking-maturity stage. These finally resulted in the shortening of whole growth period.

在春小麦整个生长发育过程中，其阶段生长和产量对气候变化的响应不完全一致：气候变化使该地区春小麦出苗期、拔节期、抽穗期和成熟期的出现时间均提前，而乳熟期出现时间推迟，导致播种－出苗期的营养生长阶段缩短、出苗－拔节期的营养生长阶段延长、拔节－抽穗期的生殖生长阶段缩短，抽穗－乳熟期的生殖生长阶段延长，乳熟－成熟期的生殖生长阶段缩短，最终造成全生长期缩短。
