Our calculation shows that qa decreasing with the simulationtime can accelerate the convergence significantly,which is somehow similar tointroducing different temperatures for visiting and acceptance probability.

为了增加收敛速率，让原来固定不动的qa随计算机时间作线性下降，对粒子数N＝12，51的Thomson问题的测试表明我们的改进效果是很明显的。qa随计算机时间作线性下降类似于对接收几率引入了单独的温度，这个温度不同于跃迁温度。

The stem flow of spruce and larch had acidulation on the soil, but the soil around the bole of spruce didn't present intensive acidity (the lowest pH of water and KCl immersion were 5.13 and 4.79, respectively), so the acidulation of stem flow is not the direct reason of spruce death.

虽然两树种树干径流对土壤均产生了酸化作用，但由于云杉树干周围土壤PH并没有出现较强的酸性（水浸pH下降到5.13，盐浸pH下降到4.79），因此，还不能认为云杉的衰退死亡与树干径流的酸化作用有直接关系。

If your pixel scale is much larger than the values quoted above, then the quality of the astrometry will suffer. If your pixel scale is too low for your local setup, then the signal-to-noise of the images may be low as each image is spread over a large number of pixels.

如果你的像素分辨率比上面要求大很多的话，那么可能导致天文测量的测量品质下降，但如果你的像素分辨率比上面要求的小很多，则会导致图片的信噪比下降，因为每个目标占据了过多的像素。

To solve the existing problems concerning cone bottom bricks, quenching ring and the vertical pipe in Chinese-built coal gasifiers based on coal-water slurry, countermeasures were put forward from the aspects of technical innovation, operation and equipment management.

针对国产化大氮肥水煤浆气化炉中锥底砖、激冷环和下降筒使用过程中出现的问题，分析了损毁原因，分别从技术改进、工艺操作和设备管理等方面提出了相应的解决对策，可以不同程度地延长锥底砖、激冷环、下降筒的寿命。

From the water pressure test and the collapsing examples, the thesis analysis the force expression of Karst collapse in water table dropping down, and presents that the additional stress from water table descending in overlying soil layer and rock, which is equal to approximately the descending depth of water table, which can be applied to about ten meters descending depth.

针对地下水位波动引发的岩溶塌陷进行了专门性研究。通过试验文章指出了岩溶区地下水位受迫下降至基岩面以下时的力学效应为：附加力在一定范围内，与在基岩面以上一样，等于水位下降的幅度值，并与盖层下基岩中洞穴的形态及体积无关。

This time there's no boat involved, instead participants are lowered down on a rope in a controlled abseil.

Activity of s AChE and GSTs was elevated in 4 strains,of which the activity of AChE and GSTs in KFQ strain and BYS strain was 1.57 fold and 2.33 fold respectively compared with susceptible strain.Activity of AChE and GSTs was decreased in one strain,activity of AChE was elevated but activity of GSTs was decreased in other 3 strains.

有4种品系可使AChE和GSTs活性提高，其中KFQ品系、LD品系与敏感品系相比，AChE的活性分别提高了1.57倍和1.44倍；BYS品系使GSTs活性提高了2.33倍；有3种品系可使AChE活性提高，使GSTs活性下降；另有一种品系使AChE和GSTs活性均下降。

From the above seems to show the failure, the author estimated that the fault is mostly the work of the subsidiary CRT circuit damage occurred because the cathode-ray tube voltage of the focus is very prone to failure similar to the above phenomenon, the phenomenon that gave rise to such failure is due mainly to display work over time, then the CRT focus very near the jack attached to a lot of dust very easily, which encountered wet dust easily lead to the air tubes of focus very significantly decrease the performance of socket contacts, then a cathode-ray tube focus to the natural voltage decline will be affected down, so that we could monitor the performance will be prone to poor focus, image display is a relatively vague.

从上面的显示故障现象来看，笔者估计该故障现象多半是显像管附属的工作电路发生了损坏，因为显像管的聚焦极电压十分容易发生类似上面的故障现象，引起这种故障现象的原因主要是显示器工作时间一长，那么显像管的聚焦极插孔附近很容易附着不少灰尘，这些灰尘遇到潮湿的空气后容易导致显像管的聚焦极插孔接触性能大大下降，那么一来显像管的聚焦极电压自然就会受到影响而下降下来，这样的话显示器也就容易出现聚焦性能不好、图象显示比较模糊的现象了。

Based on the theoretical model coupling Maxwells equation with the rate equation of 4 level inverted population, the numerical simulation is made via the FDTD method and MATLAB programs. The simulation results show that 1. With the increase of the pumping rate, both the localization of the electric field and the spectrum mode numbers will change; 2. The lasing threshold decreases by increasing the size or concentration of the scatters; 3. The lasing threshold also decreases by increasing the size of samples or strengthening the sample randomness.

在理论和实验研究的基础上，利用麦克斯韦方程与四能级反转粒子数的速率方程相耦合的理论模型，采用时域有限差分方法和MATLAB程序对随机激光泵浦阈值特性进行了数值模拟与计算，模拟结果显示：随着泵浦速率的增大，出现了阈值前后电场强度局域态及频谱模式数的改变；随着散射体粒径的增大，浓度的增大，阈值呈现下降的趋势；随着样品长度的增大，随机强度的增强，阈值也呈现下降的趋势。

Labour's vote in Barking (and in the neighbouring, renamed seat of Dagenham and Rainham, held by an influential left-wing Labour MP, Jon Cruddas) has declined sharply, from around 65% in 1997 to around 50% in 2005 as the BNP vote has increased. In 2006 the BNP won a score of council seats.

随着BNP在巴尔金的支持率上升，工党在该区的选票大幅下降（包括在后来重新命名的邻区达格南和雷纳姆，由有影响力的工党左翼议员约翰·克鲁达斯领导），从1997年的65%下降到了2005年的50%。2006年BNP赢得了该区12个地方议席。
