查询词典 expression mark

Parentheses are not necessary around the first expression of a conditional expression, since the precedence of ?

条件表达式中第一个表达式两边的圆括号并不是必须的，这是因为条件运算符？

When we embed a conditional expression in a larger expression, we usually must parenthesize the conditional subexpression.

当我们要在一个更大的表达式中嵌入条件表达式时，通常必须用圆括号把条件表达式括起来。

It is easier to read and understand a call to shorterString than it would be to read and interpret an expression that used the equivalent conditional expression in place of the function call.

阅读和理解函数 shorterString 的调用，要比读一条用等价的条件表达式取代函数调用表达式并解释它的含义要容易得多。

Unified expression for the iterative of centers is described as to deduce the conditional probability expression of the centers and data weight functions for FKHM. Finally, the partition similitude is used to evaluate the result of clustering.

在中心迭代聚类算法的统一框架的基础上，推导出FKHM算法聚类中心的条件概率表达式以及在迭代过程中的数据点加权函数表达式。

A logical expression of the form a1︿a2︿…︿an where︿is the AND operation. A particular conjunction of interest is the conjunctive normal form of a Boolean expression involvingn variables x1, x2,…,xn.

一种逻辑表达式a1︿a2︿…︿an，其中︿是AND运算，一个特别重要的合取运算是涉及n个变量x1，x2，…，xn的布尔表达式的"合取范式"。

According to induced response method, the expression in frequency domain of pressure response at the end of pipeline is derived using impulse response method and convolution theorem. The expression indicates that that transfer function is only related to the characteristics of pipeline system and the Fourier transform of flow variable only depends on the operating characteristics, and the pressure response in frequency domain is linear with the Fourier transform of flow variable.

基于激励响应法，应用脉冲响应方法和卷积定理得出了管道末端压力响应在频域中的表达式，此式表明：传递函数只与系统的特性相关，流量变量的傅立叶变换只与操作特性相关，且压力频域响应与流量变量的傅立叶变换为线形关系，根据此式在理论上能够得到管道泄漏点的重要信息。

AIM and METHODS : Immunohistochemical technique in combination with a computer assisted TV-image analysis system were used to measure the expression level of c-erbB-2 and bcl-2 proteins in 37 cases of lung squamous carcinoma and 48 cases of lung adenocarcinoma identified pathologically. The expression of c-erbB-2 and bcl-2 genetic proteins in lung carcinoma and some image signs of invasiveness of lung carcinoma were analysed correlatively.

摘 要 目的和方法：利用免疫组化技术LSAB法和计算机图像分析系统的结合，测定经手术病理证实之37例肺鳞癌及48例肺腺癌组织中c- erbB -2及 bcl -2基因蛋白的表达水平，分析其表达或共表达与反映肺癌侵袭力的影像征象的关系。

Physics concepts, theorems as well as principles are primary content of physics learning, those knowledge take on the forms by proposition . In chapter 3, the study revealed that physics proposition are mainly obtained by reasoning (inductive reasoning such as tallying method, differentiation method and covariant method, deductive reasoning such as negative expression of hypothetical inference, affirmative expression of hypothetical inference ).Then by the means of experiment, the different condition needed when applying those reasoning was explored.

由于定义性概念、定理和定律等命题知识是物理教学的主要内容，所以在第三章中首先通过研究，表明物理命题主要是运用推理策略获得的(归纳推理策略中的求同策略、差异策略和共变策略，演绎推理策略)；然后通过实验等方法研究使用策略需要的条件；最后依据前面的研究提出适合物理命题学习的任务分析方法。

Model group and the normal group were taken distilled water,rats in the Tangshukang group were taken Tanggukang powder, western medicine control group were taken Calcium Carbonateand alpha D3. once a day for 12 weeks. Ca,P, BALP,BGP in blood and bone miner density;bone mineral contents, osseous vitodynamics,the content of Ca and P in the cremains were tested respectively.The femur was taken and detected the expression of TGF-β_1imRNA , the duodenum was taken and detected expression of VDR mRNA and CaBp-D9K mRNA with situ hybridization.

分别给予糖疏康、碳酸钙阿法迪三和生理盐水灌胃给药。12周后取材，测体重、血糖、血清钙、磷、血清骨源性碱性磷酸酶、骨T-羧基谷氨酸蛋白、骨密度、骨矿含量、骨的生物力学、骨干重、灰重、骨钙、磷等指标、组织病理切片骨形态计量学指标测定、并进行维生素D受体mRNA、转移生长因子-β_1(TGF-β_1)mRNA、钙结合蛋白(CaBp-D9K)mRNA原位杂交。

There was BMP4 expression at E10 in epithelium of otic capsule. Later, BMP4 expressions were affluent in condensed mesenchyme, vestibular cartilage capsule and sense epithelium. 3. The expression pattern of Smad4 in vestibule is different from BMP4. It was not conspicuous until E15 that Smad4 expressed in macula and crista ampullaris and until E16 in periotic cartilage capsule.

BMP4从E10开始，在间充质浓聚前就有表达；间充质一开始浓聚，BMP4在其中就有较丰富的表达；早期主要表达在前庭囊及前庭囊周围的间充质，在胚胎发育的后期，其在软骨囊及前庭上皮里有广泛阳性表达。3。
