降低

Because of the aggravation of the competition, the enterprises of various countries are seeking the way to increase the benefit and lower costs ," logistics industry " is known as " the third profit source " of enterprise," circle backmost" of the economic " dark continent " for lowering costs and " key competitiveness " logistics industry in future will play an more and more important role.

由于竞争的加剧，各国的企业都在寻求提高效益降低成本的途径，"物流业"被称为经济的"黑暗大陆"，降低成本的"最后边界"，企业"第三利润源泉"。作为"核心竞争力"的物流业，正发挥越来越重要的作用。

To better understand the roles of LsrA protein in nodulation, a series of analyses of nodules using scanning electron microscopy, genetic and biochemical approaches have been carried out. Our analyses suggest that the lsrA1 nodules contain bacteroids in the invasion and establishing zone only. The lsrA gene expression is active early in the invasion zone and activated later than bacA genes. The lost of LsrA protein dramatically reduced the expression of nifA and fixK, and completely blocked the expression of the nifH gene for nitrogenase. LsrA protein functions early in the bacteroid development and it is essential for the development nitrogen fixing bacteroids.

前期的工作中，苜蓿中华根瘤菌Rm1021中90个候选LysR基因已经被定向插入突变，并筛选在自生生长时期、共生生长时期的表型，以期寻找更多在自生状态或共生固氮中有功能的LysR转录因子。1 针对前期鉴定出的共生固氮必需的lsrA基因，我们应用了一系列扫描电子显微镜技术、生物化学、分子遗传学等方法，发现lsrA基因主要在根瘤侵染区开始表达，表达时序也在侵染阶段左右，但晚于bacA基因表达；LsrA蛋白缺失后根瘤固氮区中缺乏具有固氮能力的类菌体，nifA和fixK基因的转录水平降低，nifH基因的转录被完全阻断，因此LsrA蛋白为根瘤发育所必需，是新的根瘤发育信号传导途径成员。2 通过表型筛选我们鉴定了苜蓿中华根瘤菌的oxyR基因，并研究了它的调节特性。oxyR突变后，苜蓿中华根瘤菌对过氧化氢敏感性提高，适应性降低。

Year-old a critical point when the human body, human growth and physical strength reached its peak during the year, but this is the future gradually to decline, the earliest manifestations began to slowly lose muscle strength and flexibility, and then began to decrease cardiopulmonary skills, physical The basal metabolic rate is a slight decrease year by year.

岁时人体的一个临界点，人的生长和体力在这一年达到最高峰，但这以后就逐渐地走下坡路，最早表现的肌肉开始慢慢丧失力量和弹性，然后心肺的技能开始降低，身体的基础代谢率也逐年稍有降低。

Because the cost total amount receives the active mass the influence, reduces the cost the basic symbol reduces the unit cost.

由于成本总额受到活动量的影响，降低成本的基本标志是降低单位成本。

Decrease of blood viscosity,basification of urine before chemotherapy and hydrotherapy can decrease incidence of early death of HAL.

对HAL降低血液粘滞度、化疗前、化疗中硷化尿液及水化治疗，以降低早期死亡率。

With the increasing of the concentration of alkali, the content of insolubility of the product reduces initially but increases later, the DS of product increases initially then reduces later. The product has good solubility and high DS at 10% content of alkali. The insoluble product reduces at initially and then keeps stability later with the time of basification extending. With the increasing of the content of water in system, theinsolubility of the product reduces initially and then increases later.

随着碱浓度的增加，产物中水不溶物含量先降低后增加，取代度先上升后下降，在10％时，水溶性最好，取代度最高；延长碱化时间，产物中水不溶物含量下降，之后趋于稳定；提高反应体系中水的含量，产物中水不溶物含量先降低后增加，在7％时，水溶性最好，延长分散时间，产物中水不溶物含量下降，取代度提高；醚化剂以少量多次的方式滴加，产物水溶性好。

GUP decomposed to guanidine polyphosphate GPP(at about 180℃), then to ammonium polyphosphate APP (at about 285℃), and in turn to polyphosphoric acid PPA (at about 385℃). The pyrolysis process of basswood was changed by the treatment of FRW or its components. It was discovered that BZ lose weight at quite lower temperature (165℃) than UZ did, and this may attribute to the catalytic effect of B on the pyrolysis of basswood to form char.

FRW阻燃剂及其组分均改变了木材的热解途径，其中，观察到BZ在较低的温度下（约165℃）即发生明显的失重，说明硼酸的阻燃机理除了传统理论认为的物理覆盖作用以外尚存在化学催化作；GUP 处理使紫椴木材的最大失重速率温度从375℃降低到314℃，同时失重率也显著降低，而成炭率升高；FZ的失重率低于其他处理材。

The engine CA6102 bench test results show that fuel carrying charge to assist atomization decreases largely HC content and CO content of engine exhaust emission, and economize a little fuel. It is a new method for automobile to make fuel electrified to improve mixture quality.

在CA6102发动机台架上进行了试验，结果表明，燃油带电荷辅助雾化的方法可以大幅度地降低HC和CO的含量，同时对油耗也有一定程度地降低，为在发动机上节能降排提供了一种新的方法。

Results The benzene series concentration of indoor air was gone down rapidly in 2 months.

结果 苯系物浓度在装修后两个月呈快速下降趋势，而降低到0.2～0.3mg/m3时，则降低趋势缓慢。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
