It is rare in an OLTP query for the lookup tables to be selected as the primary query tables requiring an index on the dependent table to support the join. OLTP查询中很少需要选择查找表作为需要相关表上的索引来支持联接的主查询表。
In this paper, pressure is used for a primary dependent variable and SIMPLE algorithm is used to simulate the3-dimensional turbulent flow. 本文采用SIMPLE方法,以压力为基本求解变量对三维可压缩湍流流场进行数值求解,并采用密度延迟修正将SIMPLE算法扩展到可压缩流动的计算。
Note: if claim is for the primary insured, please do not fill out dependent information. 注:如果理赔人是第一保险人,无需填写被保险人亲属信息。
To study the effects of a primary immune response to T-cell dependent antigens on central serotonin (-HT) metabolism, keyhole limpet hemocyanin ( KLH) was administered intraperitoneally to F male rats. 在F雄性大鼠腹腔注射血蓝蛋白(KLH),研究T细胞依赖抗原初始免疫反应对中枢神经系统羟色胺(HT)代谢的影响。
Economic development has transformed these ancient structures: primary education has become ever more universal and higher education ever more common; the economy has become dependent on individual creativity; knowledge has spread; and communications have become more dynamic. 经济发展彻底改变了上述古老的社会结构:初等教育变得越来越普及,高等教育越来越普通;经济开始依赖于个人的创造性;知识传播开来;交流变得更加活跃。
We model the galactic chemical evolution of primary metal element by using the instantaneous recycling approximation and the yield metal dependent which enable the problem to be handled analytically. 利用瞬时循环近似,考虑元素产率随金属丰度的变化,得出了主要金属元素星系化学演化的分析解。
This article analyzes the two primary performance parameters ( noise, longitudinal resolution) of spiral CT. The noise, independent of pitch, is a dependent function on applied interpolation algorithm. 本文分析了螺旋CT的噪声和纵向分辨率两个主要性能参数的性质:1.噪声与插值算法存在确定的函数关系,与螺距无关;
A numerical method, where the pressure is used as a primary dependent variable, is presented for the solution of the two-dimensional steady Navier-Stokes equation in general curvilinear coordinates. SIMPLE ( Semi-Implicit Method for Pressure Linked Equations) is mainly accepted. 本文给出了二维任意曲线坐标系下,以压力为主要求解变量对Navier-Stokes方程进行数值求解的方法,主要应用SIMPLE方法。
The primary trisomics from isolated microspore culture of autotetraploid Chinese cabbage and its cytological basis were studied. The results showed that ① Embryogenesis were genotype dependent. 以同源四倍体大白菜为试材,进行了游离小孢子培养获得初级三体、及其细胞学依据研究,结果表明:①游离小孢子胚胎发生能力因供体基因型而异。
Changes of synaptic terminal number of primary afferent fibers in spinal cord lamina ⅱ of morphine dependent RAT-AN EM quantitative study 吗啡依赖大鼠脊髓Ⅱ板层初级传入纤维突触性终末数量变化的电镜定量研究
Fusion protein could specifically react with the primary anti ovarian carcinoma monoclonal antibody ( COC166 9) and rat anti mouse GM CSF monoclonal antibody, respectively, and fusion proteins could also stimulate murine GM CSF dependent cell line NFS 60 cells to proliferate. 表达的融合蛋白分别能与COC166-9单抗和大鼠抗小鼠GM-CSF单抗特异结合,并能刺激mGM-CSF依赖株NFS-60细胞增殖。
The results are as follows: ( 1) The growth of wheat primary root was inhibited by the treatment of SAM, and the inhibition was dependent on the dose of SAM as well as the treated time. SAM处理对小麦初生根的生长具有抑制作用,而且这种作用存在一定的剂量和时间依赖性,即随着SAM浓度的增大和处理时间的延长,抑制作用呈现加强的趋势。
Accounting earnings is the primary information, as opposed to cash flow, dividend policy and other indicators, the information user is more dependent on earnings data. 会计盈余是公司的首要信息,相对于现金流量、股利政策等指标,信息使用者更为依赖盈余数据。
Higher export intensity goes with smaller range of enterprise productivity promotion; its primary cause is that export enterprises are too dependent on export market, especially after controlling the processing trade influence, this kind of causal relation obtains a promotion in high export intensity sector. 出口密集度较高反而对企业的生产率提升作用较小,其主要原因在于过度依赖出口市场,尤其是在控制了加工贸易的影响之后,这种因果关系在出口密集度较高的区间得到提升。
According to the actual national conditions that our country is in the primary stage of socialism, it is unrealistic to be totally dependent on the Government to ensure the resettlement in form of money as compensation. 根据我国尚处于社会主义初级阶段的实际国情,完全依靠政府通过货币形式进行安置保障补偿是不现实的。
