1·These conclusions aid to measure drainage rate of gas and fixing on maintenance period of coal laneway.

这些结论对于检测煤层瓦斯抽放率以及合理确定煤巷的维护周期具有重要的参考价值。

2·In controlling factors of high permeability, the deformation of coal, coal fracture direction, ground stress and drainage rate were discussed.

在渗透率控制因素方面，从煤体变形、煤层裂隙方向、地应力和排采方面对其进行探讨。

3·While, birch has much faster drainage rate and highest solids content of the wet web, though its low retention properties need to be further improved.

相比之下，桦木浆具有较快的滤水速率和较高的湿部固含量，但其留着性能还有待改进。

4·The drawbacks are acacia's low drainage rate and low initial wet web strength, which are bottlenecks to the high paper machine speed especially at the web forming.

需要改进的地方是：它的滤水速率和湿纸幅强度较低，这些将是现代高速纸机湿部的瓶颈所在。

5·Cellulasepoor xylanases can reduce the content of fines in the light weight coated secondary fibers and increase drainage rate under appropriate enzymolysis condition.

低纤维素酶活木聚糖酶在合适的酶解条件下，能降低轻量涂布纸二次纤维中细小组分含量，增加浆料的滤水速度。

6·The measurement method is demonstrated valid in outburst elimination by the examination of remnant gas pressure, pre-drainage rate and the zonal verification during the coal roadway driving.

残余瓦斯压力和预抽率的检验以及煤巷掘进期间的区域验证，均证明按该方法布置的预抽钻孔，消突效果有效。

7·Incision length, blood loss, operative time, drainage tube removal time, hospitalization time and recurrence rate of 2 groups were observed.

观察2组切口长度、出血量、手术时间、引流管拔除时间、住院天数及复发率等情况。

8·Disturbance of the bedrock changes drainage and runoff patterns, which may increase the rate of erosion. Trenching is the exploration activity that most disturbs bedrock.

干扰的基岩排水和径流的变化模式，这可能增加侵蚀率。挖沟是勘探活动，大部分干扰的基石。

9·The hemorrhage rate of venous drainage unobstructed was lower.

引流静脉通畅者其出血率低。

10·Stone columns installed in clayey soils function as drainage passages. They effect to hasten the rate of consolidation and enhance the shearing strength of the surrounding soils.

植入粘性土中的碎石桩是地基中的排水通道，它们具有加快桩周土的固结速度和增大桩周土的抗剪强度的作用。
