可保持的

The enterprise sustainable development is that in course of the enterprise development, the enterprise not only achieve its business target and enhance the market status, but also gained the ability of success in the one-up competitive field and the to-be outstretched management condition, and make the enterprise be prosperous in long-term. And there are many theoretic about the sustainable development.

企业可持续发展，是指企业在追求自我生存和永续发展的过程中，既要考虑企业经营目标的实现和提高企业市场地位，又要保持企业在已领先的竞争领域和未来扩张的经营环境中始终保持持续的盈利增长和能力的提高，保证企业在相当长的时间内长盛不衰。

The content of GA exhibited on imbalance in different tissue of seedling. The content of IAA, GA and ZR of male sterile lines were lower than maintainer lines to some degree, especially in the stage of archesporial and meiosis. IAA, GA and ZR are the important plant hormone which regulates lots of activity of plant. Their deficient must interfere on the development of anther and result in abortion.

在花期叶片激素含量在保持系和不育系之间变化较大，蕾期不育系的IAA、GA和ZR含量出现不同程度的亏缺，尤其是从小蕾期到大蕾期阶段，ogura不育系、改良萝卜不育系的IAA、GA和ZR含量都极显著低于保持系IAA、GA和ZR是植物体内重要的信号物质，可调节植物的多种生命活动，其亏缺影响花粉的正常发育，从而引起败育。

We suppose that there is a presently undefined subfraction of stem cell population that exists in a number of tissues beyond embryonic development. We term them postembryonic pluripotent stem cells. They differ from embryonic stem cells in that they gradually lose some differentiation potentials during development and adopt some special phenotypes once within a certain tissue. They can give rise to different kinds of stem cells; therefore, help to maintain balance during development and metabolism. They provide cells not only for the damaged tissues they reside, but also for damaged tissues different from them by migration triggered by proinflammatory cytokines or growth factors.

我们认为在胚胎发育后的多种组织中都存在一类原始干细胞群体，它们和造血干细胞、神经干细胞等多能干细胞不同，后者只能分化为特定胚层的细胞，而这类原始干细胞可分化为不同胚层的组织细胞；另一方面，它们区别于胚胎干细胞，在妊娠期间会逐渐失去部分分化潜能，并且会出现一些特殊表型或者分子标志，我们称其为胚胎后亚全能干细胞，这类干细胞具有下列特性：可分化为不同胚层的细胞，分布于身体的所有组织和器官，具有相同的表型或标志；他们在胚胎期存在于一些或全部的组织和器官中，可分化为不同类型的多能干细胞并在生长发育和新陈代谢中维持这些多能干细胞保持平衡；可以参与机体自我修复和更新，不仅能分化为所在器官的组织特异性细胞，参与器官重塑，也可以在炎症因子或者生长因子的趋化作用下，远处转移修复受损组织。

FYB---double-direction angular contact thrust ball bearing is a bearing unit composed of an integral outer ring, a group of sectile inner rings, steel balls, cage assemblies and sealing.

FYB—双向推力角接触球轴承是由一整体外圈、一组剖分式内圈、钢球和保持架组件及密封组成的轴承单元，其结构紧凑体积小，可双向受力，旋转精度高，并可在承受很高径向负荷同时承受一定的轴向负荷。

The results showed that the decreasing of the hardness was inhibited, the 1st fracture drop off was maintained, and those such as the production of the ethylene , the degrading of the chlorophyll, the decreasing of the titratable acid were inhibited, as well as the changing of the enzyme activities. And 1-MCP can keep a better condition of the inner structure of the tomato.

结果表明，1-MCP的处理减缓了硬度的下降，在一定程度上可以保持果实的脆度，抑制乙烯生成，阻止叶绿素的降解，降低可滴定酸的减少，对酶活变化起到了一定的抑制作用，同时较好地保持了番茄果肉组织结构的完整性。

A stainless steel roof reflects the sunlight, while airconditioning will maintain cab temperatures at 25℃, even with ambient temperatures of 55℃.

不锈钢的顶棚可反射太阳光，即使外界环境温度高达55℃，空调也可使驾驶室的温度保持在25℃。

These results indicated that the 1600 bp band derives from CMS mtDNA and can be used as a RAPD marker to distinguish A and B plants at seedling stage,and the bands other than the 1600 bp can be used to distinguish WA and DA cytoplasms.

这些结果表明1600bp带源于线粒体DNA，可用作苗期鉴别不育系和保持系的RAPD标记；1600bp以外的带可用于鉴别野败细胞质和矮败细胞质。

But, if I may even flatter myself that they may be productive of some partial benefit, some occasional good; that they may now and then recur to moderate the fury of party spirit, to warn against the mischiefs of foreign intrigue, to guard against the impostures of pretended patriotism; this hope will be a full recompense for the solicitude for your welfare, by which they have been dictated.

如果我们在一个称职的政府领导下保持团结，在不久的将来，我们就可以不怕外来干扰造成的物质破坏；我们就可以采取一种姿态，使我们在任何时候决心保持中立时，都可得到它国严正的尊重；好战国家不能从我们这里获得好处时，也不敢轻易冒险向我们挑战；我们可以在正义的指引下依照自己的利益，在和战问题上作出抉择。

Based on the performances of different varieties, it is considered that the Guangxi landrace, African landrace, Myanmar landrace and ICPL87119 adapted to Karsts stone mountain areas and hilly lands, and could be used for feed, water and soil conservation and ecological protection, firewood forest and so on.

根据不同品种的表现：广西品种、非洲品种、缅甸品种I、CPL87119比较适应喀斯特石山区荒地、山地种植，可作为饲料、水土保持、生态保护、薪炭林等用途，ICPH8、IC-PL87091可作蔬菜和粮食用，其中ICPL87091是一个比较有希望的品种。

The results of yield and water use efficiency in field show that yield can not reduce, butwater use efficiency can increase significantly from 〓 to 〓 when alternateirrigation by interval furrow compared to the well-irrigated plant. In 1997 and 1998,the resultsof field trails show that seeds yield is above 8000kg/ha meanwhile irrigation water can save from〓 to 〓 or 〓, about more than 33% water can be saved, water-saving profit is significant.

大田小区试验产量和用水效率结果表明：隔行交替灌溉后灌溉用水效率明显增加，可由常规灌水的〓提高到〓以上，总用水效率〓以上，1997-1998年两年试验结果表明籽粒产量保持8000kg/ha以上高产水平的同时灌溉用水量可由〓降至〓，甚至〓，节水达33.3％以上而不引起产量下降，节水效益显著。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
