为了降低微生物絮凝剂M-25的生产成本，以查氏母液为基础，采用替代碳源和氮源的方法，开发出了廉价的替代碳氮源：淀粉和尿素。

The results show that: the degree of deformation and yield-region will decrease as the fraction coefficients increasing; the influence of fraction coefficient f1 between clip-pieces and anchor plate is more remarkable than f2 between anchor plate and under board, the influence of f2 can be negligible.

有限元分析结果表明：随着摩擦系数的增大，锚环的变形和塑性屈服区域面积将逐渐减小；夹片与锚环之间摩擦系数f_1对锚具特性的影响要比垫板与锚环之间摩擦系数f_2所产生的影响要显著得多，后者的影响几乎可以忽略。

The result from the QDA test showed that incubation at 50℃ for 1 weeks can accelerate the flavor formtion and decrease the off-flavor of Anchovy sauce.

感官分析结果表明，鱼露发酵的后期阶段，在50℃短期保温可以起到加速风味成熟与降低不良风味的作用。

Results show that:(1) For each particle size of andalusite, variation tendency of the properties of the material is generally the same: the maximum of bulk density, compressive strength and rupture strength appears in the range of 5%-10% content of fiber, these properties of the material remarkably decrease as the fiber content exceed 10%; while at the same fiber content, the properties of the material increase with the increase of firing temperature.

结果表明：(1)对于不同粒度的原料，性能变化规律大致相同：在同一烧成温度下，体积密度、常温耐压强度、常温抗折强度在5％～10％之间出现峰值，加入量超过10％之后材料的性能明显下降；在相同的纤维含量下，随着烧成温度的提高，试样的各项性能均有所上升。

Androgynus was a kind of hyperaccumulator in Cd, with critical value of 50 mg/kg, above which would cause poison in S. androgynus, and even dead when it was up to 800mg/kg; transfer coefficient would decrease with the increase in treated concentrations, which show that plant would protest Cd against transferring to above-grounds and causing poison.

以上结果说明五指山野菜是Cd超积累植物，且50 mg/kg时是五指山野菜正常生长的临界值，高于此浓度，将对其产生毒害，当浓度为800 mg/kg时，植株出现死亡；随处理浓度的增加，转移系数逐渐变小，说明植物在高Cd胁迫下阻止Cd向地上部分转移而产生更严重的毒害。
