串

The binary + operator performs string concatenation when one or both operands are of type string. If an operand of string concatenation is null, an empty string is substituted. Otherwise, any non-string argument is converted to its string representation by invoking the virtual ToString method inherited from type object.

由此可知 C#的加号运算子预设就支援字串串加的功能，只要一群字串串接的物件中只要有一个以上的物件型别是「字串」的话，就会全部变成「字串相加」，只要遇到「非字串」的物件，预设会使用继承至 object 物件的 ToString 方法进行转型，让所有物件都变成「字串」后进行相加动作。

Maybe daily to see the printer that you are printing a parallel port or USB interface and the computer is connected to; however, the printer prints in addition to the parallel port or USB interface, you might have a serial port, we must not think that this is just a well-display serial interface, because as soon as the printer of the parallel port or USB interface experience a breakdown in normal use, the serial port can make their own role, help printer to serial communication fashion emergency printing.

或者我们常日见到的打印机，都是堵住打印并口或USB接口与计算机拆开的；不过也有的一些打印机除了具有打印并口或USB接口之外，还不定具有一个串口，我们万万必给以为这个串口不光是个部署而已，因为一旦打印机的并口或USB接口碰到障碍不克不及变态搁置时，该串口不离能阐发自己应有的功用，帮忙打印机以串行通讯的方法来达不败济急打印。

The results are as follows.(1) Long train electrical stimulation at the dMNF facilitated myoelectric activities of genioglossus and phrenic muscle.(2) Short train electrical stimulation of dMNF, when delivered in the inspiratory phase, caused prolongation of myoelectric activities of genioglossus and phrenic muscle; but when delivered in the expiratory phase, myoelectric activities of genioglossus and phrenic muscle were shortened.(3) Long train electrical stimulation at the vMNF inhibited myoelectric activities of genioglossus and phrenic muscle.(4) Short train electrical stimulation of vMNF caused shortening of myoelectric activities of genioglossus and phrenic muscle, when delivered in the inspiratory phase, but a prolongation when delivered in the expiratory phase.(5) The effects of microinjection of glutamate to dMNF and vMNF were similar to those of electrical stimulation.

结果如下：(1)长串电脉冲刺激dMNF引起颏舌肌和膈肌肌电活动明显增强；(2)短串电脉冲刺激dMNF，当刺激落位于吸气相时，引起颏舌肌和膈肌在吸气相的肌电活动延长，当刺激落位于呼气相时，引起颏舌肌和膈肌在呼气相的肌电活动提前终止；(3)长串电脉冲刺激vMNF使颏舌肌和膈肌肌电活动明显被抑制；(4)短串电脉冲刺激vMNF，当刺激落位于吸气相时，引起颏舌肌和膈肌在吸气相的肌电活动提前终止，当刺激落位于呼气相时，引起颏舌肌和膈肌在呼气相的肌电活动延长；(5)在dMNF和vMNF分别微量注射谷氨酸钠，其效应与电刺激结果基本一致。

In the presence of L-isoproterenol (through local infusion into area CA1), the theta-pulse stimulation with the parameter of 10 Hz, 150 pulses/train, 1 train, a frequency weakly modifying synaptic strength, induced a robust LTP, and this effect was blocked when DL-propranolol was co-administered. By contrast, the theta-pulse stimulation with the parameter of 5 Hz, 150 pulses/train, 3 train, a frequency strongly modifying synaptic strength, induced a significantly smaller LTP when DL-propranolol was administered into area CA1. Accordingly, DL-propranolol impaired rat's spatial learning in the water maze when infused into area CA1 20min pretraining.

正常情况下对突触传递效能仅有微小调制作用的10Hz的θ节律刺激（每串150个脉冲，1串），在CA1区局部给予L-异丙肾上腺素后，显著地诱导出LTP，这一效应可被DL-心得安所阻断；相反，正常情况下对突触传递强度有显著调制作用的5Hz的θ节律刺激（每串150个脉冲，3串），在CA1区局部给予DL-心得安后，所诱导出的LTP被显著压抑。

The result shows that the more component an insulator string has, the less uniform the distributed voltage is. The u max of side-string is 6～7% lower than that o...

结果表明：绝缘子串元件数越多，其分布电压越不均匀；边相串的umax值比中相串的约低6％～7％；双串的umax值比单串的约低5％～7％。
