查询词典 addition

Because of the associative law for addition, we can define multiplication based on addition, a b means a+a+…+a,adding a with b times.

正是由于加法的结合律使得我们可以在加法的基础上定义乘法，就是重复加法的简便运算：a b=a+a+…+a，对a重复相加b次。

In the 2nd one we have already a+(b+1)= a+b'='=+1,this is the first step of associative law for addition,further more we can verify the associative law and commutative law for addition.

而在第二条中已经有a+(b+1)= a+b'='=+1，就是加法结合律的第一步，进而可以验证加法交换律和结合律。

We cannot always have associative law for operations, for instance, we did not have this law for mixed addition and multiplication,neither for subtraction, 2+3 2+1≠(2+3)(2+1)=5 3,（2-3）- 2≠2-（3-2）,this is why we have to set the rule in operations that "doing inside bracket at first and out side afterwards, doing multiplication and dividing first and addition and subtraction afterwards".

注意运算的结合律并不是永远对的，比如加法和乘法的混合运算就没有结合律，减法也没有，2+3 2+1≠5 3，（2-3）- 2≠2-（3-2），因此我们运算中总是规定先括号内再括号外，先加减后乘除。

Besides, compounding bacteria was preferred for highland barley wine production by liquid fermentation with its addition level 0.4 %～0.6 % of the total weight of highland barley powder, fermentation time between 40～72 h, and water addition level 4～6 times of the volume of highland barley powder.

结果表明，优化发酵工艺条件可提高青稞酒的出酒率，对酒的色泽、口感等感官质量无影响；复合菌种适宜于液态发酵生产青稞酒，添加量为青稞粉重的0.4 %～0.6 %；发酵时间为40～72 h；加水量为青稞粉的4～6倍。

The inclusion of George Winston (the label founder and a friend of Beamer, aside from his status as a new age virtuoso) is an addition to the album, but perhaps not the addition one might wish for.

George Winston (公司创始人和Beamer的朋友，他在new age上有一席之地)的参与为专辑增光添彩，但他的参与也许并不是听众们希望的那样。

RVA's 139,200 sq foot East Wing addition, which unites the historic 1916 Beaux-Arts building and the 1971 Marcel Breuer addition, is the first of three planned wings.

In addition, this paper deals with the influence of technological conditions, especially the addition of bentonite.

Sb can combine with Cu and P to form a low melting point compound which lowers the melting point of binary Cu-8P eutectic alloy by nearly 200℃. Bi and Cu can create compounds with low melting point(270℃) distributing at the boundaries and that is the reason why the melting point of (Cu-8P)-Bi is lower than that of binary Cu-8P eutectic alloy. The eutectic cluster can be refined with the addition of Fe, and that is the reason why the addition of Fe can decrease the melting point of Cu-8P alloy. Two means of decreasing the melting point of Cu-8P are found.

一定量的Sb与Cu， P形成低熔点相，从而大幅降低了Cu-8P合金的熔点，使其熔点降低近200℃；加入少量Bi后， Bi与Cu在共晶团晶界上形成熔点为270℃左右的低熔点化合物，且Bi的加入明显细化Cu-8P合金共晶团，从而使Cu-8P合金的熔点降低；加入Fe能明显细化Cu-8P合金的共晶团，使层片间距由8μm减为2μm以下，并使共晶团由层片状向短棒状转变，虽然Fe与Cu形成熔点为806℃的高温相，但Fe的细化作用使得Cu-8P合金的熔点降低，但降低幅度不大。
