查询词典 P-C

"Logicians distinguish two main types of implication, material and strict. Proposition p materially implies proposition q if and only if the material conditional p q (read "if p then q") is true"

逻辑学家将蕴涵分成实质的和严格的两种主要类型。p命题实质蕴涵q命题，若且唯若实质条件pq为真

Mele (2001), drawing on empirical research regarding lay hypothesis testing, argues that selectivity may be explained in terms of the agent's assessment of the relative costs of erroneously believing p and ~p.

Mele(2001)，基于对普通假定测验的经验研究，认为选择性也许可以从代理者对去错相信了p和去错相信了-p中的相对成本评估上来解释。

Szechuanensis had mesophyte characteristics which were different across elevations; these differences contributed to their adaptation to a range of drought environment; the leaf thickness, vein thickness, vessel number, palisade mesophyll thickness and the P/S ratio were increased, while vessel diameter was reduced with increasing elevation, but no significant differences in epidermal thickness and spongy mesophyll thickness were found along the elevations.

随着海拔的升高，叶总厚度、栅栏组织厚度、P/S值和主脉厚度以及导管分子数目等均呈增大趋势，而导管分子直径减小；表皮厚度、海绵组织厚度等无明显差异。2多元统计分析显示，叶肉组织厚度和叶片总厚度主要受温和度的影响，并随着温和度的降低而增大；P/S值和导管分子数目主要与年降水量和土壤含水量的变化有关，随着水分增加，P/S值和导管分子数目增大，而导管分子直径减小。

Calculations indicate that Ni-Ni interaction in Ni81B19 alloy is stronger than metallic bond in pure Ni. However, the Ni-Ni interaction in pure Ni is stronger than that in Ni80P20 alloy. Direct B-B contact in Ni81B19 alloys appears in our simulation, however no direct P-P contact in Ni80P20 alloys is found.

其次，在Ni的d电子和B的p电子之间存在着强烈的相互作用，形成Ni原子和B原子间的强共价作用。B和P的加入后使催化反应中的活性位Ni的活性d电子数增加，在合金中起修饰作用。

Results 58 cases all appeared amenorrhea.hystera and hysteromyoma grow downwards obviously.the minification are 29.0% and 40.1%(p.01).the fsh、lh、e2、p in blood also lower than before treatment.

结果：58例患者在治疗期间均出现闭经，子宫及子宫肌瘤体积均明显缩小，缩小率分别为29.0%和40.1%(p.01)。血fsh、lh、e2、p测定治疗后平均水平也较用药前下降。

A fast algorithm for computing the linear complexity and the minimal polynomial of a binary sequence with period 2〓p〓 is proposed, and generalized one for determining the linear complexity of a sequence with period p〓q〓 over GF .

提出确定周期为2〓p〓的二元序列的线性复杂度和极小多项式的一个快速算法，并推广为计算GF上周期为p〓q〓序列的线性复杂度和极小多项式的快速算法。

Utilizing the controlling parameter λ, we integrate p=1 and p=∞ the two minimizing diversion method...

使用控制参数λ将p=1和p=∞两类极小化偏差量的方法结合起来得到了一种更加灵活且适用范围更广的模糊判断矩阵的互补一致性修正方法。

Now this two-premiss argument7 is simply an instance of modus tollens: if p then q; not-q; therefore not-p.

现在这两个前设的论证也就是归谬法：如果p那么q，非q，所以非p。

Using Pell equations on A,we give a new proof of the well-known fact that ifthe ideal class number of a real quadratic function field K = k equals to 1,thenD must be P or QR, where P,Q,R∈A are monic and irreducible ,and Q,R have odddegrees.

二我们应用A上的Pell方程这一初等方法重新证明一个已知的结果：实二次函数域K = k理想类数为1时， D只能为P或QR，其中P，Q，R∈A首一不可约且Q，R次数为奇数。

This paper has firstly defined the factor struture M/P of commutatiuely residual monoid M by its sub-monoid P, then we have studied its properties and given out some isomorphism theorem.

本文首先定义了交换剩余幺半群M相对于其子半群P的商结构M／P，然后研究了它的性质并给出了一些同构定理。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
