查询词典 presence

However, the action variable is a more conspicuous presence, insofar as its name as well as what it does—the code is easier to understand. The per- son and howmany variables are used for their values while the action vari- able is used as a flag.

然而，action变量代表了一种更明显的出现，不光是它的名字还有它的作用—其代码很容易理解。person和howmany变量都是对其值起作用，而action变量则被用作一个标志。

MQO silicone resin as raw material,one kind of conformal coating with high stability for electronic circuit board assemblies was developed,which showed short cure time in presence of a functional additive.

涂覆液固化时间短(20min内完全表干)，涂膜具有良好的粘附力且阻燃性好(氧指数为49%)，介电强度高(37kV/mm)，完全可以满足实际电路板涂覆生产线要求。

At the same time, sufficient and necessary conditions for holding the control system robust stability are analyzed in the presence of the process additive and multiplicative uncertainties often encountered in practice, and correspondingly, the on-line rule for tuning the adjustable parameters of the decoupling controller matrix is provided.

同时，对于实际中常见的被控过程的加性和乘性不确定性，分析了控制系统保证鲁棒稳定性的充要条件，从而给出在线整定解耦控制器矩阵的可调参数的规则。

该论文的结果对研究CdSe 量子点与DNA的相互作用有一定的指导意义，但是：1。

Results: The most common locations of PIP were at the margin of both lower lobes and associated with local pleural thickening and adhesion. The density of nodule in which CT attenuation value was 15~60 HU (26.9±13.5HU) was lower than that of PLC. Most of them were round/round-like and irregular in shape. The interior density of lesion was inhomogeneous. The presence of calcification or multiple cavitations, straight margin sign, hole sign and without hilar and mediastinal adenopathy were of great significance in the diagnosis of such kind of disease.

结果：炎性假瘤多位于两肺下叶，邻近胸膜增厚、粘连，病灶密度偏低（平扫CT值15~60HU，平均26.9±13.5HU），与周围型肺癌比较有统计学差异，其形态以圆形／类圆形和不规则形多见，病灶内密度多不均匀，可见钙化及多发空洞，边缘呈平直状、周围见毛玻璃样改变及肺门纵隔无淋巴结肿大等征象对本病的CT诊断有意义。

However, chloroplast matK genes are indispensable since in nonphotosynthetic parasitic plant, Epifagus virginiana and fren, Adiantum capillus-veneris which chloroplast genome has rearrangememt, the chloroplast matK is functional even being a free-standing from with dismissed trnK exons.The chloroplasts of Psilotum, moss and liverworts all have trnK5'-matK-trnK3' structure, but it is found that matK is a pseudogene in hornwort Anthoceros formosae. Little is known in other lower land plants, it is the purpose of this thesis to examine the presence of chloroplast matK gene is these taxa.

叶绿体trnK5'-matK-trnK3'的结构在高等植物相当一致，但先前研究发现两个matK脱离trnK而存在的例子，像是叶绿体严重退化的寄生植物Epifagus virginiana及因叶绿体基因重组而导致trnK外显子丢失的铁线蕨，它们的matK仍然具有完整的开读框，显示了matK的确十分重要而不可缺失，藓苔类和松叶蕨也被证实具有trnK5'-matK-trnK3'的结构，但是在角藓中却发现其matK是伪基因。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
