Considering "addition theorem of probabilities", the above idea can be expressed as follows: Assum that a beam passes through a partition with two slit and arrives a screen. The probability of the event that an indivedual particle falls on somewhere of the screen under the condition that two slit open simultaneously, is equal to the sum of two probabilities of the same event under that two slit open in turn.

考虑到"概率的加法定理"，这种看法可表成："当一个拉子束通过一个带有两条缝的隔板到达一个屏上时，在两条缝同时打开的条件下单个粒子落在屏土某处的概率，等于在两条缝轮流打开的条件下该拉子落在该处的两个概率之和。"

At mid-northern latitudes, Antares sets shortly after nightfall at this time of year.

在中北纬度每年这个时候，心大星在日暮后很快就落下了，在更北方会落得更快。

If the slope＇s rockmass is low counter-inclined or thick-interbedded with soft interlayer, its failure model is inclined to be tilting-collapsing; if the slope＇s rockmass is homogeneous and thin-bedded with hard discontinuity, its failure model is inclined to be splitting-collapsing; if the slope＇s rockmass is low sequence-inclined with densely deep tectonic joints and weathering fissures, its failure model is inclined to be sliding-collapsing.

当缓倾内层状岩质边坡的岩层较厚，岩性呈软硬互层状产出，或岩层间软弱夹层较厚时，常发生倾倒-崩落式破坏；当缓倾内层状岩质边坡的岩层较薄，且岩性较均一，或层间结构面力学性质较好时，常发生拉裂-崩落式破坏；当缓倾角层状岩质边坡岩层倾向坡外时，在陡倾构造节理和风化卸荷裂隙切割下，常发生滑移-崩落式破坏。

The slump and the time of slump are tested through the method of slump test, and the properties of concrete are calculated and analyzed. The study denotes that for C20 grade concrete, the value of the shear yield stress σ0 and plastic viscosity η is the smallest when the fly ash contains 20% weight of Portland cement; for C60 strength grade concrete, the value of plastic viscosity is the smallest when fly ash contains 20% weight of Portland cement and the value of the shear yield stress σ0 is the smallest when fly ash contains 30% weight of Portland cement.

利用改良坍落度筒的实验方法对坍落度和坍落时间进行测试，并进行相应的计算与分析，实验结果表明：强度等级为C20的混凝土，粉煤灰掺量为20%时粘度和屈服应力值最低；强度等级为C60混凝土，粉煤灰掺量为20%时，其粘度最低，而屈服应力值在粉煤灰掺量为30%时最低。

Proposing simple evaluation methods and evaluation values are the key factors affecting the popularizing of self-compacting concrete technology. The advantage and disadvantage of several methods for evaluating the workability of self-compacting pumpcrete, such as slump, bleeding under pressure, slump flow, the outpour time of inverse slump cone, the flow speed of Orimet meter,...

探讨了坍落度、压力泌水、扩展值、中边差、倒坍落筒流下时间、Orimet仪的流出速度、L型流动实验等多种评价免振捣泵送混凝土工作性能的指标及其优缺点；经对比分析并结合实验研究和工程实际，提出了实用的新拌免振捣混凝土工作性评价指标及其合理取值区间：坍落度一般应控制在 230~260mm，倒坍流下时间 8~15s，扩展值 600~700mm，中边差值≤25mm，压力泌水实验中的S10不超过 40%， V140在 40~110mL。

The results show: 96.7% of CG appeared within the range of 40 to 55 dBz, and the center of maximum CG density always coincided with the center of intense echoes, but CGs seldom appeared above 65 dBz. often concentrated around the area with VIL greater than 40 kg · m-2, and the center of maximum CGdensity frequently located around the margin of the center of VIL.

结果表明在 MCS 强雷暴演变过程中：①总地闪数的96.7%集中落在 CR 为45～55 dBz 的回波区域内，在 CR 大于60 dBz 的强回波区域内地闪总数却很少；地闪密集中心的位置与 CR 大于等于50 dBz 的强度中心常常重合；②地闪密集中心与 VIL 中心常常不重合，常落在 VIL 高值中心的边缘或落在 VIL 为20～30 kg · m-2的区域中；在 VIL 小于20 kg · m-2的地方存在较为活跃的地闪。

As for the mid-June 2006 Mei-yu case, the assimilation of both kinds of data can help the simulation of radar reflectivity. Further investigations show that the assimilation of dropsonde and QuikSCAT data produces stronger southerly environmental winds in the Bilis case, resulting in a better simulated track than the runs without these data. In these runs, the simulated tracks are too far to the south compared with the observed. In the Kaemi case, the tracks of simulations without dropsonde/QuikSCAT data assimilation were shifted to the north/south of the observed track, respectively.

从影响实验研究发现，同化投落送及QuikSCAT资料后，碧利斯台风个案於模拟后期具有较强的南风分量，使其模拟路径不至於像未同化该两种资料者过於偏南；凯米台风个案同化投落送资料后於模拟后期具有较弱的南风分量，而同化QuikSCAT资料后则具有较强的南风分量，使其模拟路径不至於像未同化投落送及QuikSCAT资料者过於偏北及偏南，而与观测路径较为接近。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
