The results reveal that the annual volume of surface water resources out of the debouchure of the Shiyang River has been decreased by 15.91% compared with that during the period from the 1950s to the 1990s, the volumes of groundwater recharge, spring water resources and inflow to the lower reaches have been decreased by 42.92%, 84.3% and 75% respectively, but the volume of pumped groundwater has been increased by 10 times.

结果表明：自20世纪50~90年代，石羊河流域出山地表水资源减少了15.91%，地下水补给资源减少了42.92%，地下水开采量增大了近10倍，泉水资源衰减了84.3%，进入下游的水资源减少了75%。

PUC19 plasmid were successfully enriched and purified from the E. coli DH5α under the magnetic fields. The obtained plasmid retained native the bioactivity to be used for restriction enzyme digestions and cell transformations.

用这种方法成功地从大肠杆菌DH5α浓缩和纯化得到了pUC19质粒，该质粒具有生物活性，可直接用于限制性酶切和细胞转化等分子生物学下游操作。

Upon FGF binding, specific membrane receptors dimerize and autophosphorylate, then activate several downstream signaling pathways including Ras-MAPK.

FGF通过结合细胞表面的FGF受体，使其二聚化并自体磷酸化，活化后的FGF受体具有酪氨酸激酶活性，进而活化胞内下游多条信号通路。

To achieve this, the or each steam generator pipe (22, 50, 60) has a respective downpipe section (34, 52, 62, 64), which is approximately vertical and through which the flow medium can flow downwards and a respective riser pipe section (36, 54, 66, 68) connected downstream of the downpipe on the flow medium side, which is approximately vertical and through which the flow medium can flow upwards.

为达到此目的，按本发明这一根或每根蒸汽发生器管(22、50、60)分别包括一个近似垂直布置可被流动介质沿向下的方向流过的下降管段(34、52、62、64)和一个沿流动介质流向连接在该下降管段下游的、近似垂直布置并可被流动介质沿向上的方向流过的上升管段(36、54、66、68)。

In order to better study important role of CaM in cell cycle regulation is necessary to try to find CaM downstream effectors in a cycle of cells.

为了更好地研究CaM在细胞周期调控中的重要作用，就要试图找到CaM在周期细胞中的下游效应因子。

The results showed that OsAgpS1a transcripts and the reporter gene GUS driven by the OsAgpS1a promoter had a similar expression pattern that abundantly expressed in endosperms but very low in leaves, whereas OsAgpS1b transcripts and the reporter gene GUS driven by the OsAgpS1b promoter own other similar expression pattern that expressed at a low level in leaves, roots and early development endosperms of rice.

结果表明，两个启动子与其下游转录本的表达模式完全一致，即OsAgpS1a转录本和OsAgpS1a上游启动子控制的GUS基因主要在胚乳中高水平表达，在叶片中有很低水平的表达；而OsAgpS1b转录本和OsAgpS1b上游启动子控制的GUS基因主要在叶片和胚乳发育早期低水平表达。

Currently, vitamin prices have jumped has a very small space, the key is how long it can maintain a state of high prices, which will be subject to two factors, on the one hand, the domestic raw material prices of the leading business-to-vitamin weak, if the international correlation Game industry inversion occurred, the performance of domestic enterprises will also be affected, on the other hand, feed the downstream industries affected by the economic downturn, demand for vitamins, but also will affect the performance of the company.

目前，维生素价格上涨有一个非常小的空间，关键是如何能长时间保持高价格，将会受到两个因素一方面，国家，国内领先的业务原材料价格上扬维生素弱，如果国际相关游戏行业反转发生后，国内企业的业绩也将受到影响，另一方面，饲料受经济衰退影响的下游产业，对维生素的需求，而且会影响性能公司。
