The different kinds of coal ash have obviously different influences on concrete slump and concrete slump losses because of the different fineness, water requirement ratio and ignition loss, and the fine coal ash with low ignition loss can more obviously restrain the concrete slump losses.

随着粉煤灰掺量增加，混凝土早期强度随着粉煤灰掺量而变化，当掺量在20％左右时，对7天强度影响不大，而当掺量＞30％时，早期强度明显降低；但掺粉煤灰混凝土后期强度增长较快，而且在掺量＜30％范围内随粉煤灰掺量增加而增大。 3。粉煤灰混凝土具有十分良好的工作性，流动性及填充性，易于泵送。

As for the direct reactions of ketones or aldehydes and DyI_2, the formation of products can be controlled by adjusting the quantity of DyI_2, when DyI_2 is used as 1 equiv.

对于醛、酮直接与DyI_2的反应，则可以通过调节DyI_2的计量来控制产物的生成，当DyI_2的用量和醛或酮是等当量时，得到的是频那醇偶联产物；而当DyI_2的用量是两倍当量时，得到的就是相应的醇。

For example. If I were to touch a hot coal, an unwelcoming burning sensation would trigger a signal in my brain telling me to drop it, and the next time given the opportunity, I would not touch another red coal again.

举个简单的例子，当我触碰一块燃烧着的煤球时，那种可恶的灼痛感会向我的大脑发送一个信号让我去丢掉它，那么以后当我再次面对这种红热的煤球时，我就绝不会再贸然伸出我的手臂。

When you shift to a thread that is a close vibrational match to your present one, the change may be barely detectable; when you shift to a vibrationally different thread of possibility, it may suddenly seem you are living an entirely different life.

当你转换到一条接近你当前的时间线上时，改变机会不可能被察觉，当你转换到一个存在不同可能性的时间线上时，你可能立刻看起来向过着一种完全不同的生活。

Oregano is a useful decongestant when inhaled; it also helps trigger the release of digestive enzymes when consumed.

当吸入时牛至是一种有用的解充血药；当食用时它也帮助激活消化酶的分泌。

另一个声波的类型是周期波，当你击打一个铃时，击打下去的那一个瞬间跟拍手有一点相像，声音由铃的振动产生，当铃持续发出声音时，它的震动是以一个特别的频率进行的，这个频率与铃的大小和形状有关，而这个振动造成了铃周围的空气也以相同的频率振动，这使得铃声透过空气的压力波传递到更远的地方，以声音的既有速度进行，持续震动的压力波看起来跟以下这个图很像

Based on radiative transfer theory,the reflection properties of cirrostratus consisting of hexagonal ice crystals or equivalent spheres are computed by using the adding-doubling method,respectively.The results show that the Mie scattering calculations at the region of λ≈3.0 μm give good agreement with the hexagonal ice crystals.

根据辐射传输理论，应用累加法，分别计算了由冰晶粒子和等效球形粒子构成的卷层云的多次散射特性，计算结果表明当入射波长λ≈3.0 μm时，等效球Mie理论可以很好地用于计算卷层云的反射特性，但是当λ。8 μm时，尤其在可见光区，将引起显著的误差。

When you have a short-term investment goal you need to know that the money will be there when you need it; that means keeping the money in low-risk investments such as bank C.D.

当你有一个短期的投资目标时你需要知道：当你用钱时钱在哪里，也就是说你应该把钱投到低风险的地方比如银行 C.D。

The experimental results show that when TCAR is about 700 ℃ XN for limestone is maximum, and the optimum TCAR for dolomite is about 650℃. Although XN for limestone is much higher than dolomite, the difference of their YN is little when TCAR is in 650~700 ℃. And if TCAL is beyond 1050 ℃ XN for limestone decays sharply, but it is negligible to dolomite. XN for dolomite is far higher than limestone in the high TCAL. XN for limestone decreases with the particle size increasing, and there is an optimum particle size range with particle size increasing which XN for dolomite reaches maximum in. The particle size plays a more important role in limestone carbonation process than dolomite.

结果表明：TCAR为700℃时石灰石的XN最高，白云石则在650℃时XN最高，在650～700℃时白云石的XN远高于石灰石，但它们的YN相差不大；当TCAL超过1050℃时石灰石的XN急剧衰减，而白云石的XN则衰减程度不大，在高温煅烧时白云石的YN比石灰石更高；随粒径的增大，石灰石的XN逐渐减小，而白云石则存在最佳的粒径分布使XN最大，粒径的变化对石灰石的XN影响更大。

The intersection problem of simple directed triple systems with λ=2 is completely solved, namely, it is proved that for v ≡0,1 (mod 3), v ≥3,there exist two simple DTS( v ,2)s intersecting in s triple if and only if, s∈{0,1,2,…,2v(v-1)/3},s≠[2v(v-1)/3]-1, while v≥4 s∈{0,2,4},while v

解决了单纯二重有向三元系的相交数问题。即证明了对于任一正整数v≥3，v≡0，1（mod3），存在两个单纯二重有向三元系相交于s个公共区组的充要条件是：当v≥4时，s∈｛0，1，2，…，2v（v－1）／3｝，s≠［2v（v－1）／3］－1；当v＝3时，s∈｛0，2，4

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
