何时进行SMBF6蓄电池的手动再充电和均衡充电?如何进行?

答案

参考答案:

当因某种原因整流器不能浮充或停电时间较长而引起电池电压降低时,需要对电池进行再充电,以均衡蓄电池的电压。

当蓄电池在事故放电时,整流器能自动给蓄电池充电,直到正常值转为浮充电运行。在事故放电后,运行人员应检查整流器是否能够进行强充。在事故放电后,运行人员应将开关置手动位置,然后以该组电池额定容量的10%的电流进行充电。待电压的密度正常后,再继续稳定3h以上,并通知有关人员对整流器进行检查。

名词解释
单项选择题

Cooperation is the common endeavor of two or more people to perform a task or reach a jointly cherished goal. Like competition and conflict, there are different forms of cooperation, based on group organization and attitudes.
In the first form, known as primary cooperation, group and individual unite. The group contains nearly all of each individual’s life. The rewards of the group’s work are shared with each member. There is an interlocking identity of individual, group, and task performed. Means and goals become one, for cooperation itself is valued.
While primary cooperation is most often characteristic of preliterate societies, secondary cooperation is characteristic of many modern societies. In secondary cooperation, individuals devote only part of their lives to the group. Cooperation itself is not a value. Most members of the group feel loyalty, but the welfare of the group is not the first consideration. Members perform tasks so that they can separately enjoy the fruits of their cooperation in the form of salary, prestige, or power. Business offices and professional athletic teams are examples of secondary cooperation.
In the third type, called tertiary cooperation or accommodation, latent conflict underlies the shared work. The attitudes of the cooperating parties are purely opportunistic; the organization is loose and fragile. Accommodation involves common means to achieve antagonistic goals; it breaks down when the common means cease to aid each party in reaching its goals. This is not, strictly speaking, cooperation at all, and hence the somewhat contradictory term antagonistic cooperation is sometimes used for this relationship.

Which of the following is an example of the third form of cooperation as it is defined in Paragraph 4

A. Students form a study group so that all of them can improve their grades.
B. A new business attempts to take customers away from an established company.
C. Two rival political parties temporarily work together to defeat a third party.
D. Members of a fanning community share work and the food that they grow.
