强劲的西南风场、低空急流，向英德地区源源不断地提供了充足的水汽；近地面层处于低槽边缘，位势不稳定能量增多，为持续性强降水的产生提供了足够的触发机制。

Has a remarkably wide range, though it is difficult to achieve (the high b makes the first string very taut such that it will break easily), and may not play well on an acoustic guitar (the low C is too low to resonate properly in a standard guitar's body). Luthier Todd Keehn claims to have been the first guitarist to adopt an all-fifths tuning, his being arranged G-D-a-e-b'-f#', and he has made an all fifths tuned guitar that can be seen at his website, http://tkinstruments.com/.

这个调弦的音域相当地宽，但是也很难达到要求（高音B使第一弦崩得非常紧，容易断）这个调弦在原声吉他上的效果也不理想（低音C太低在普通的箱琴上无法产生共鸣）据说Luthier Todd Keehn是第一个用这种调弦的吉他手，他还用 G-D-a-e-b'-f#调弦，他的全五调弦的琴可以在他的网站上看到 http：//tkinstruments.com/。

The test result shows that the furfural refining lube oil from Liaohe low-freezing crude oil has low wax content and can be processed into qualified LVI base oils after removing a little naphthenic wax .

试验结果表明：辽河低凝原油润滑油糠醛精制油蜡含量很低，脱除少许环烷蜡即可生产出合格的LVI基础油，润滑油溶剂脱蜡有一最佳油剂比，随着脱蜡温度的下降，润滑油脱蜡量增加，脱蜡油凝点明显降低。

Study participants included 19 women ages 22 to 55 who were allowed to select the diet plan they preferred - either a low-carbohydrate diet or a low-calorie, macronutrient balanced diet recommended by the American Dietetic Association.

参与研究的包括19名妇女年龄22至55谁被允许选择的饮食计划，他们宁愿-无论是低碳水化合物饮食或低热量，均衡饮食元素所建议的美国饮食协会。

The optimized projects of eliminating low frequency torque ripple in this subject are to make use of low speed and high torque permanent magnetic synchronous motors.

给出了低速大转矩无齿轮传动系统消除低频转矩脉振的优选方案是采用低速大转矩稀土永磁同步电动机的结论。

Similar to the border trap capacitance at low-frequency C-V curves, additional recombined charge per cycle at low-frequency charge pumping measurements could be attributed to the repetitive recombination of majority and minority carriers which instantly tunnel into and out of the border traps located near the high-k/oxide interface.

如同在低频电容—电压图形中的边界缺陷电容值一般，在低频电荷泵浦方法中所量测到的额外每单位循环再结合电荷载子数目，皆可归因於反覆的多数与少数载子再结合，而此一现象主要发生於高介电常数介电层/二氧化矽氧化层介面附近的边界缺陷。

This technique has many advantages such as easy operation,high reso-lution,high repetition,low man-hour ,and low cost etc.

此项技术具有操作简单、分辨率高、重复性好、费时少，成本费用极低等优点。

According to the experiment results of degradation in field, degradation mechanism of the biodegradable mulch film can include four stages: the first, the material surface appeared deficiency while the surface area and interstice increased of material in the action of natural environment and microorganism; the second, along with the surface area and interstice of material increased and the gap strengthened, the chemical chain of the high polymer's principal chain broke as a result of the hydrolysis or the enzymatic effect in the action of hydration, causing the molecular weight and mechanics function descended; the third, the molecular of high polymer split the low polymer after its physical mechanical function descended, the material decomposed the fragments, the mass defect intensified; the fourth, the low polymer of fragments form in the natural environment, the microorganism, the biological enzyme became the smaller fragments, thus absorbed by the phagocytes, or further turn into CO2 and H2O due to hydrolysis.

根据田间降解试验结果推测，生物全降解地膜的降解机理可能包括四个阶段：第一，在自然环境、微生物作用下，材料表面出现缺陷，同时表面积增大、空隙增多；第二，随着材料表面积的增大、空隙的增多，吸水性增强，在自水合作用下，高聚物主链由于水解或酶解而使化学链断裂，导致分子量和力学性能下降；第三，在其物理机械性能下降后，高聚物分子链断裂为低聚物分子，材料裂解为碎片状，质量损失加剧；第四，碎片状低聚物在自然环境、微生物、生物酶作用下进一步水解变成尺寸更小的碎片，从而被吞噬细胞吸收，或进一步水解，生成CO2和H2O。

Because music elements tended to be hard-panned to one side, this caused some serious problems; if any low frequency boost was added to the music on just that one side, the imbalance in low frequency energy would cause the cutting stylus to cut right through the groove wall when the master lacquer disc was cut.

因为音乐元素倾向于被很猛烈的放到一边，这导致了相当严重的问题：如果一边增加了低频的能量，那么两边的低频不平衡性就会立刻显现出来。
