Back-lying leg raise: Back lying, arms be straight, palms face the floor, and put the arms to the sides of the body.

仰卧抬腿：仰卧，双臂伸直掌心向下放在体侧。

Barrier Gate. Unplug on three porcelain inserted into AC power safety plug, the blowing of the bondid, and fusealways have been resulting in phenomena: on the UN-effectual circuit (pulse－width electrocircuit) has no effect, the work will still be able to make its output stability and normal positive and negative 15 volts DC power supply voltage, and make the control circuit is working properly; and on the high current circuits works have a great effect, make it output a serious shortage, and cause the machine to the highest 速增 not.

关闸。拔下配电不活上的三个瓷插式互换电源保障插头查抄，发掘其洋一相的保障丝还来烧不续，并由此变成了此刻的本体：差小电流电路的处事操纵感化，仍可使其输入安定和变态的侧负15不起直流电源电压，并使把持电路的处事变态；而差不小电流电路的处事有很不小感化，使其输入惨重不敷，并导致机不缓增不到最矮不缓的本体。

In order to determine further the profile of scrolls,the structural characteristics of superchargers with double-sided scrolls were analyzed and the principle of determining initial involute angle s was presented on the conditions of definite initial involute angle s,radius of base circle,and depth of scrolls.

在渐开线起始角、基圆半径和涡旋齿深度确定的条件下，为进一步确定涡旋齿的齿形，对双侧涡旋增压器的结构特征进行分析，提出始端渐开角的确定原则。通过吸气腔和排气腔的容积计算，结合回转角与渐开角的关系，给出涡旋齿始端和终端渐开角的计算方法。结果表明：该计算方法能较准确地确定涡旋盘的结构尺寸，从而可估算出整个压气机的尺寸是否满足汽车上有限的安装空间

Reaction of L-tyrosine with benzyl bromide in the presence of copper sulfate led to the protection of phenol group on the side chain of L-tyrosine to give H-Tyr-OH in 45% yield via a copper complex intermediate.

酪氨酸与溴化苄在硫酸铜存在下反应，选择性地在其侧链酚羟基上引入苄基保护基，通过反应条件的优化，反应产率达到45%。

The countermeasure to lessen flow rutting is advanced and the design idea of coordinated combination design for asphalt layers is proposed. The use of binder course of graded broken stone not only decreases the trend of lateral flow deformation at high temperature but also reduces the lateral displacement of surface layer and middle layer.

给出了减少流动性车辙产生的对策；提出了沥青结构层协调组合设计的理念；指出了级配碎石联结层的使用不仅会减少高温下沥青上、中面层的侧向流动变形趋势，还会减小上、中面层的横向位移。

大小齿轮均采用渗碳淬火钢进行制造，并采用硬齿面加工方法加工而成，强度很高。小伞齿轮和大伞齿轮均通过轴承座装入下壳体中，两轴承座法兰下设有调整垫，用于调整齿轮副接触区的位置和齿侧间隙。

Based on the relevant movement between hard shaper cutter and grinding wheel, the movements of grinding wheel are studied. The shaping grinding point and the shaping grinding edge are made up with. In order to easily compare when shaping errors and cutting edge"s angles are the most excellent, uniform expressions for convex curved rake face of hard shaping cutter and spatial cutting edge curve are separately developed. The distributions of new profiling cutter"s shaping errors and cutting edges angles are analyzed. The relevant grinding wheel and cam are designed. Due to this paper, a new profiling hard shaping cutter has been manufactured successfully. At last experiments are made to test the performance of hard shaping cutter and all kinds of precision of hard gear.

本文直接从插齿刀与砂轮之间的相对运动关系出发，单独研究砂轮的运动，提出砂轮成形磨削点和砂轮成形磨削刃的概念；分别建立圆柱砂轮和圆锥砂轮磨削后硬齿面插齿刀的波形前刀面方程及空间切削刃方程；为便于比较何种情况下插齿刀的构形误差和切削角度能同时达到最优，分别对磨削五种不同硬齿面插齿刀所用的砂轮进行了廓形设计，并分析了插齿刀的构形误差和侧切削刃切削角度的分布规律；为插齿刀波形前刀面的磨削加工设计了相应的凸轮，用所设计的凸轮和近似的砂轮成功地制造出新构形法硬齿面插齿刀；最后进行插齿加工试验，检验新构形法硬齿面插齿刀的抗崩刃能力、耐磨性及被加工硬齿面齿轮的各项精度。
