First,since the signal is very feeble, so we designed a kind of high performance amplifier; and for theneed of the power supply of the output system, we designed an eximious boost circuit.

针对肌电信号特点，设计制作了高增益、高性能的微弱信号放大器；针对输出系统供电的需要，设计并实现了良好的升压电源模块。

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。

"The extragalactic background is very faint, and it is easily confused with the bright emission from the Milky Way," says Ackermann. With the background isolated in their studies (these background measurements are published in the 12 March edition of the journal Physical Review Letters ), Ajello and Ackermann then began to compare it with observations of relatively nearby active galaxies with black holes (called active galactic nuclei, or AGN).

系外伽玛射线背景是非常微弱的，而且很容易受到系内辐射源的干扰，（ Ackermann 等人对背景值的测量公布于3月12日的《物理评论快报》上）， Ajello 和 Ackermann 同时将这个测量结果与附近已被观测过的相对活跃的星系黑洞参数进行比较，这些参照对象有个专有名词，称为活动星系核， AGN 。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
