Loaches were exposed to different extent polluted water with waste cells and the SOD and CAT activity in animals was detected after 48 hours and 72 hours exposed.

将泥鳅暴露于不同浓度的废旧干电池污染液中，于48 h、72 h测定其超氧化物歧化酶及过氧化氢酶的活性，结果显示低浓度、短时间内SOD、CAT活性被诱导，随着废旧干电池污染液浓度的增大和暴露时间的延长，酶活性被抑制。因此SOD、CAT可作为生物标志物来监测水生态系统的污染

As the brazing temperature was low or the holding time was short, lots of low-melting M3B2 were precipitated in the central part of the brazing seam.

当钎焊温度较低或保温时间较短时，钎缝中央生成大量的M3B2；随着钎焊温度的升高及保温时间的延长，钎缝中M3B2、MC减少，M23C6增多、长大。

Long time sliding causes fatigue failure of UHMWPE, a lot of big spalls are produced around the counterpart edge, debris from UHMWPE/PP blend does not show apparent increase with sliding time.

长的磨损时间导致UHMWPE疲劳破坏，产生大量的磨屑，而随磨损时间的延长，UHMWPE/PP表面的磨屑并无明显的增加。

With the extension of heating tine, the radical scavenging rate of Shiitake water extract was increased gradually in five heating groups and was much higher than that in not-heating group when the heating time exceeded 5 h.

随加热时间的延长，香菇水提液的自由基清除率逐渐提高，加热时间超过5h后，香菇水提液的自由基清除率显著高于不加热组，但加热处理对香菇粗多糖的自由基清除率无明显影响。

The reaction temperature and reactants concentration have important influence on the morphologies of the products.

反应温度和反应物浓度对产物的形貌影响较大，反应时间对产物的形貌影响不大，但随着反应时间的延长，产物的粒径有增大的趋势。

Election officials are extending office hours today to give poll voters additional time to pick up an absentee ballot.

选举部延长办公时间使选民能有时间提取一份缺席邮寄选票。

Assessment with a pressure wire also did not add time to the procedure, which took an average of 70 minutes using conventional angiography and 71 minutes with the pressure wire, probably because of the time saved in placing an average of one fewer stent per patient.

此外，采用压力导丝进行评价并不会延长手术时间，采用传统的血管造影术平均需要70 min，而采用压力导丝也只需要71 min，这很可能是因为采用压力导丝，每例患者可平均少用1个支架，从而节省了部分时间。

It was found that the structure parameters and effective volume charge density were influenced strongly by concentration of monomers.

界面聚(来源：A0fBC论f6文网www.abclunwen.com)合时间对复合膜孔径影响不大，随着反应时间的延长，膜的厚度和电荷密度增加。

Business Scope: 1, ONLY licensing carbide circular saw blades, the products manufactured using imported materials, as compared with the same price products to extend the service life of more than 10%; applicable to all kinds of wood (including solid wood, particleboard, MDF and various MDF), aluminum alloy, rigid plastic, acrylic and other materials cutting; 2, the Company may in accordance with customers cutting materials and cutting of different specifications to choose custom-made special carbide circular saw blades; 3, In order to fully utilize resources, reduce costs, the company offers carbide tooth circular saw blades for the overall processing services; 4, the company's carbide circular saw blades used to provide full-service customers, in view of: a, blade matrix used for a period of time will produce deformation; b, saw in the use of the course will be part of tooth loss; c, saw the use of a period of time would not sharp blade; above phenomenon will not only greatly reduce blade life, at the same time will affect the use of effect.

ONLY牌硬质合金圆锯片，该产品全部采用进口材料制造，与同价格产品相比使用寿命延长10%以上；适用于各种木材（包括实木、刨花板、中纤板及各种密度板）、铝合金、硬质塑料、压克力等材料的切割；2、本公司可根据客户切割材料和切削方式的不同选择订做特殊规格硬质合金圆锯片；3、为充分利用资源、降低成本，本公司提供硬质合金圆锯片整体换齿加工服务；4、本公司对硬质合金圆锯片使用客户提供全方位服务，针对：a、锯片基体使用一段时间后会产生变形；b、锯片在使用过程中会出现部分齿脱落；c、锯片使用一段时间后刀刃会不锋利；以上现象出现，不仅会大大降低锯片使用寿命，同时会影响使用效果。

The zero-coupon or PIK bond possesses one additional attraction for the promoter and investment banker, which is that the time elapsing between folly and failure can be stretched out. This is no small benefit. If the period before all costs must be faced is long, promoters can create a string of foolish deals - and take in lots of fees - before any chickens come home to roost from their earlier ventures.

此外零息与 PIK 债券还有一项特点使得支持者与银行家更愿意推行，就是东窗事发的时间可以再延长，这点可是相当的重要，如果交易所衍生的后果要很长一段时间才会浮现，那幺支持者就可以在这段期间做更多的交易，从中赚取更多的手续费，直到事件东窗事发之前。
