查询词典 primary

For example, some primary and secondary copper smelting plant is still in use behind blast furnace process, sulfur dioxide utilization rate of only 65%; primary and secondary lead smelting enterprises, commonly used sintering pot lead smelting process, flue gas concentration is low, can not use the sulfur into the atmosphere each year up to 25 million tons.

Some characteristic ratios suggest the picrites and ankaramites were derived from asthenospheric mantle, and high Os/Ir ratios reflect the involvements of pelagic sediments. Pd/Ir versus Ni/Cu diagram implies that the picrites and ankaramites were not primary magmas, but MgO-high basalts with excess olivines, whereas Pd versus Cu diagram suggests a S-undersaturated primary magma.

一些铂族元素的特征比值指示了苦橄岩和富辉玄武岩起源于软流圈地幔，而高的w/w比值则暗示了源区中有深海沉积物的加入。w/w-w/w图解说明本区的苦橄岩不是原始岩浆，而是原始的高镁玄武岩中有过剩橄榄石的加入，而w-w图解则说明原始岩浆硫不饱和。

For a constant impedance load or a constant current load, if regulating the secondary voltage by making the changer ratio higher, the primary voltage will get much lower while the load power is restoring, and the power will then lose balance. For a constant power load or a motor load, since the change of OLTC has no or little influence on the load power, the voltage of primary side almost has no change whether the tap operates or not. The influence on the voltage stability with respect to the dynamic restoring load which is sensitive to voltage is also discussed.

对于恒阻抗和恒电流型负荷，在变比上调恢复副边电压的情况下，负荷功率恢复，又使原边电压下降，可使系统功率失去平衡，而对于恒功率负荷和电动机负荷，OLTC的变化不会引起负荷功率的恢复，OLTC的变化对系统电压稳定有利；同时研究了对于一般电压敏感和具有动态恢复特性的负荷，反调分接头对电压稳定性的影响。

Furthermore, the teaching content from the point of view, the teaching of English in primary schools there are two characteristics, one English and Chinese have a completely different pronunciation, writing characters, expressions and sentence structure, which give Chinese-speaking students in learning In a certain resistance to thinking; Second, as a new subject, in a primary school English teaching of the Enlightenment, the entry-stage system there is no need to learn grammar, tone of voice training and day-to-day grasp of the language is still dominant.

再者，从教学内容上看，小学英语教学存在着两个特点，一是英语与汉语之间有着完全不同的发音、字形书写、表达方式和句子结构，这给以汉语为母语的学生在学习中造成一定思维阻力；二是作为一门新学科，小学英语教学处于一个启蒙、入门阶段，系统的语法学习尚无必要，语音语调的训练及日常用语的掌握仍是主导。

Methods:1297 students of primary and middle school were randomly investigated with test anxiety test before graduating examination.results: the higher the grade , the higher the score of tat; the prevalence rate of test anxiety is higher in boy students than girl students and the level of test anxiety in boy students was increasing with grade.conclusions: the prevalence rate of test anxiety is common in the students of primary and middle school before graduating examination .it is necessary to give mental intervention.

对随机抽取的小学、初中、高中毕业班的学生进行考试焦虑测验表问卷调查。结果：随着年级的增加其tat分值也显示出增加；在性别比的构成上则显示出男生的焦虑水平随着年级的增高而增加；男生中、重度考试焦虑的发生率高于女生。结论：考试焦虑的发生率在中考和高考的学生中较为普遍，应予以重视。

In order to control the steam temperature at the outlet of the primary superheater of a 1000 t/h once-through boiler, the start up condition is analyzed in accordance with the concept of " isenthalpic switchover" and it is suggested that the ratio of fuel feed to steam flow through the primary superheater before the switchover during cold startup be used as the criterion for judgement.

为控制1000吨/时直流锅炉低温过热器出口汽温，本文系根据&等焓切换&原理对锅炉启动工况作了分析，并提出以冷态启动切分前锅炉燃料量与低温过热器工质通流量的比值作为判断依据。

The complexity of bodywork decides variety of it's error. The station and primary factor which cause error is inconstant change and using correlation analysis can find out the primary factor.
