采用以下（）措施主要用来降低重力坝坝基的扬压力。

某地区拟建一座500kV变电站，站地位于Ⅲ级污秽区，海拔高度不超过1000m，年最高温度+40℃，年最低温度-25℃，变电站的500kV侧，220kV侧各自与系统相连，35kV侧接无功补偿装置。该站运行规模为：主变压器4×750MVA，500kV出线6回，220kV出线14回，500kV电抗器两组，35kV电容器组2×60Mvar，35kV电抗器2×60Mvar。主变压器选用3×250MVA单相自耦无励磁电压变压器。电压比为（525／）/（230/）±2×2.5％/35kV，容量比为250MVA/250MVA/66.7MVA，接线组别为YNaod11。

本期的35kV电容器组是油浸式的，35kV电抗器是干式的户外布置，相对位置如图，电抗器1L、2L，电容器1C、2C属1号主变，电抗器3L、4L，电容器3C、4C属2号主变，拟对这些设备作防火设计，以下防火措施哪项不符合规程？依据是什么？（）

A.每电容器组应设置消防设施

B.电容器与主变压器之间距离15m

C.电容器2C与3C之间仅设防火隔墙

D.电容器2C与3C之间仅设消防通道

C．可表现为肌肉痉挛性抽搐

D．可表现为肌腱反射减弱或消失

E．可能死于急性脑水肿

D．糖尿病肾病
E．糖尿病合并尿路结石

Motivation is "the driving force within individuals that impels them to action." And goals are the sought-after results (1) motivated behavior.
Motivation can be either positive or negative (2) direction. We may feel a driving force toward some object or condition, (3) a driving force away from some object or condition. For example, a person may be impelled toward a restaurant to fulfill a need, hunger, and away (4) an airplane to fulfill a need of safety. Some psychologists refer to positive drives (5) needs, wants or desires, (6) negative drives as fears or aversions. (7) , though negative and positive motivational forces seem to differ dramatically (8) terms of physical and sometimes emotional activity, they are basically similar in (9) they both serve to initiate and sustain human behavior. (10) this reason, researchers often refer (11) both kinds of drives or motives as needs, wants and desires.
Goals, (12) , can be either positive or negative. A positive goal is one toward (13) behavior is directed and it is often referred to as an approach object. A negative goal is (14) from which behavior is directed away and it is sometimes referred to as an avoidance object. Since both approach and avoidance goals can be considered objectives of motivated behavior, most researchers refer to (15) types simply as goals. Consider this example. A middle-aged woman may wish to remain (16) attractive as possible. Her positive goal is to appear desirable, and (17) she may use a perfume advertised to make her irresistible. A negative goal may be to prevent her skin (18) aging, and therefore she may buy and use face creams. (19) the former case, she uses perfume to help her achieve her positive goal -- attractiveness; in the (20) case, she uses face creams to help avoid a negative goal -- wrinkled skin.
