The educator’s job is not increase motivation per se(本身）but to discover, initiate, and sustain student’s motivation to learn, and to engage in activities that lead to learning

5.1 Edward Chace Tolman (1886-1959) Born in Newton,Massachusetts. Received his B.S.degree fromthe Mass.institutes of Technology inelectrochemistry in 1911

Note that in the case of repeated roots of the denominator, a pole of multiple order contributes only a single residue. To evaluate F(s)ds by integrating around a closed contour enclosing the entire left half plane, note that if F()0 faster than-for large s, the integral along the curved part of the contour is zero

1范围 本方法适用于地面水、地下水及生活污水造纸废水、石油化工废水、炼焦废水与印染 废水等中的溶解性的H2S、HS、s2以及存在于颗粒物中的可溶性硫化物、酸溶性的金属硫 化物

The operational amplifier (hereafter OP-AMP)is developed in the 1940s primarily for use in analog computers, made cheaply and readily available in the late 1960s through integrated-circuit technology. The actual construction of a modern OP-AMP is indeed very complex, involving many transistors, diodes, resistors and capacitors

光的波长与频率的关系由光速确定，真空中的光速 c=2.99793×1010cm/s，通常c≈3×1010cm/s。光的波长 λ和频率ν的关系为 ν的单位为Hz，λ的单位为cm
