采用四川和江西水稻土为供试土壤，通过接种土壤微生物的混合培养及土壤悬液培养试验，测定厌氧培养过程中Cr和Fe的浓度变化，研究了不同浓度铬酸盐的微生物还原能力及不同铬酸盐浓度下氧化铁的还原能力。

During the whole course of the dynamitic development and evolvement of redox zones, concentrations of TOC, sulfide, NH+4-N, HCO-3, CO2 and Fe2+ increased with time and decreased with distance; concentrations of NO-3 and DO decreased with time and increased with distance; SO2-4 concentration decreased first and then increased over time; but decreased with distance.

在氧化还原带的整个演化过程中，各带中TOC、硫化物、NH+4-N、HCO-3、CO2和Fe2+等物质的浓度随时间的推移而升高，随离污染源距离的增加而降低；NO-3和DO等物质的浓度随时间的推移而减小，随离污染源距离的增加而升高；SO2-4的浓度则随时间的推移先减小而后增加，随离污染源距离的增加而降低。

Results showed that cultivation of milk vetch significantly lowered concentrations of heavy metals and soil comprehensive pollution index, and more or less the same as the treatments of organic reagents, except for effect on decreasing Zn and Cd concentrations and comprehensive heavy metal pollution index, which were not so big in scale. When compared with the treatment of milk vetch + organic reagents, the treatment of milk vetch did not differ much in heavy metal concentrations and comprehensive pollution index.

结果表明，紫云英处理显著降低土壤重金属浓度和土壤综合污染指数，下降幅度与CK比呈极显著差异；除土壤Zn、Cd浓度和土壤重金属多因子综合污染指数的下降幅度显著低于有机试剂处理，其他与有机试剂处理均无显著差异；紫云英处理与&紫云英＋有机试剂&的交互作用处理相比，土壤重金属浓度和土壤综合污染指数的下降幅度无显著差异。

Blood samples were collected twice a day at the time of administration,and then these patients were submitted to operation for removal of hydatid cysts with collection of cyst fluid and endocyst wall of solitary hydatid cysts.

测定不同部位，不同状况下的每只囊的囊液、囊壁中的 AlbSO 浓度，分别作出囊液—血浆；囊壁—血浆；囊壁—囊液的 AlbSO 相对分布图，得出了血药浓度和囊液、囊壁药物浓度均有正比关系的结论。

The results showed that BTH, SA, OAA and Na2SiO3 had significant induction effects, and the optimum concentration of four chemicals for resistance induction of melon against Erysiphe cucurbitacearum were 0.35, 1.0, 30 mmol/L and 10 mmol/L respectively.

各种诱导剂的最适诱导浓度分别为BTH 0.35 mmol/L、SA 1.0 mmol/L、OAA 30 mmol/L、Na2SiO3 10 mmol/L；适宜浓度下的诱导效果分别为：72.4%、49.9%、43.4%和34.9%。磷酸氢二钾(K2HPO4)在供试浓度范围内对甜瓜抗白粉病的诱导作用不显著。

The finer sizes have lower minimum explosible concentrations and higher explosion intensity. When particle sizes of coal dust are less than 75 μm,minimum explosible concentrations and explosion intensity approach a limiting value. In the concentration range measured ( less than 700 g/m3), maximum explosion pressures, maximum rates of pressure rise and explosion indices increase along with the increase of coal dust concentrations. Explosion intensity rapidly enhances along with ignition energy augmenting. Explosion reaction is weak while ignition energy is less than 1 kJ.

煤粉越细，其爆炸下限越低，爆炸烈度越大，但煤粉细到75 μm以下后，这种变化趋势趋缓；在所测浓度范围内(小于700 g/m3)，最大爆压、最大压力上升速率和爆炸指数均随煤粉浓度增大而增大；爆炸烈度随点火能增大而迅速增强，点火能小于1 kJ时各煤样在不同浓度的爆炸都很微弱。

Fifty-seven kinds of polycyclic aromatic hydrocarbon were detected by qualitative method,and sixteen kinds of those were mensurated by quantitative method.The results suggested that the average concentration of chry was the highest,21.83 ng/m3;the average concentration of fluoranthene was the second highest, 21.14 ng/m3; the mass c...

并对16种多环芳烃定量测定，结果表明：以屈艹为最高，平均值为21.83ng/m3；荧蒽次之，平均值为21.14ng/m3；苯并芘的质量浓度为14.52ng/m3，不满足GB3095-96中的质量浓度限值。2001～2003年检测结果对比表明，部分监测点空气中多环芳烃的浓度有下降的趋势。

Detector the gas strength which examines the sensor transforms the electrical signal, passes commits a footfault the cable to transmit the controller, the gas strength is higher, the electrical signal is stronger, when the gas strength achieves or surpasses the alarm point which the warning controller establishes, the alarm apparatus send out the alarm, and may start the solenoid valve, the exhaust fan substandard association equipment, removes the hidden danger automatically.

探测器将传感器检测到的浓度转换成电信号，通过线缆传输到控制器，浓度越高，电信号越强，当浓度达到或超过报警控制器设置的报警点时，报警器发出报警信号，并可启动电磁阀、排气扇等外联设备，自动排除隐患。
