The learning model of WBQ bases on the investigative internet study .In this learning model , in the circumstance of internet , the investigative learning activity of learner is self-antimating ,self-guiding and it must have the definite cognitive inquirment and learning direction ,and it is an internet learning behavior . A learner can search for the correct starting point ,basing on self-level and the choice of study materials ,the establishment of study goal can be made by his need .In the course of study ,the learner can have a self-reconsideration, have a self-evaluation, and can expand the free space of study activity .

WBQ（Web-based Query）学习模式是基于因特网的探究式学习，在这种学习模式下，学习者在环境下的探究学习活动是自我驱动、自我引导的，具有明确的认知需要和学习方向，是一种内在的学习行为，学习者根据自身的水平，寻找适当的学习行为起点，学习材料的选择、学习目标的确定由学习者根据自己的学习需要而定，在学习过程中学习者进行自我反思、自我评价，真正扩大了学习者学习活动的自由空间。

The enzyme activity of LpsA2 was increased to 250% or above by 1 mmol/L Co2+, Hg2+ and Zn2+, respectively. The activity was also elevated to 110.7% and 138.0% by 15% dimethylformamide and dimethyl sulfoxide, and 352.7% and 189.7% by 0.1% and 1% Span-20, respectively. The enzymatic properties of LpsA2 from S. avermitilis were characterized that may provide the fundament to the screening of bio-engineered bacteria and the industrial applications in food processing and drug synthesis.

avermitilis的脂肪酶基因lpsA2进行了异源表达和酶学功能鉴定，不仅为脂肪酶的研究积累了更多数据，也为具有优良性能的脂肪酶生物工程菌的筛选奠定了基础，更为其在食品加工、药物合成等工业生产中的应用提供了依据。

Based on the assessment of mycelial biomass, xylanase activity and content of xylose-equivalent reducing sugars in their liquid cultures, the isolate CY4786 was best for xylanase production in a basal medium containing birchwood xylan (10.0 g/L)as a sole carbon source, yeast extract (2.5 g/L) and sea salts (15.0 g/L) with initial pH 7.8. When assayed at the optimized regime of 50℃ and pH 4.6, the activity of xylanase produced by CY4786 in 7d liquid culture at 25℃ reached 1.07 × 104 unit/mL.

根据培养液中菌丝生物量、木聚糖酶活力和木糖等价还原糖含量等指标的测定，菌株CY4786在起始pH 7.8的木聚糖-酵母膏-海盐液体培养基中25℃下震荡(100r/min)培养7d产酶最佳；粗酶液在50q℃和pH 4.6的优化条件下进行测定，木聚糖酶活力达到1.07×104U/mL。

This is not to say that there was no top-down activity or that all bottom-up activity will produce the desired effect.

这并不是说没有由上而下的活动，或者一切由下而上的活动都会带来理想的效果。
