As illustrated in Figure 1-5 a binary digit in any position other than the unit's position has weight depending on its position in the number. A Has a weight of 1 in the units position, 2 in the 2'sposition, 4 in the 4's position and so on.

The results indicate that multiple reflections are favorable to the increase of depth. When the focal position is above the surface, the absorptive intensity on the front decreases, so the cutting depth decreases. When the focal position is below the surface, the position on the front with the maximum power intensity is downward. The intensity distribution is toward the deeper position, the cutting depth increases. But if the negative focal distance is extremely big, the intensity of the deeper position attenuates sharply with the increase of focal radius and light distances, so the depth deceases.

正离焦切割时，前沿吸收的总激光功率密度减小，切割深度减小；负离焦切割时，最大激光功率密度值的位置下移，使得前沿功率密度分布朝着深部推进，切割深度增加，若负离焦量过大，表面光斑直径和光程增加，更深位置的功率密度减小，切割深度减小；随着激光功率增加、切割速度减小，则前沿弯曲程度减小，被激光直接照射的前沿部位增长，前沿吸收激光功率密度增加，切割深度增加。

S1 is then changed to position 1. The voltage stored on C1 is inserted between the output and inverting input of the amplifier and the output of the amplifier changes by VIN to maintain the amplifier input at the input offset voltage. The output then changes from (VOS + IbiasR2) to (VIN + IbiasR2) as S1 is changed from position 2 to position 1. Amplifier bias current is supplied through R2 from the output of the amplifier or from C2 when S1 is in position 2 and position 1 respectively. R3 serves to reduce the offset at the amplifier output if the amplifier must have maximum linear range or if it is desired to DC couple the amplifier.

接着 S1 拨到位置 1，使 C1 的电压加在放大器的输出端和反相输入端之间，(由于电容端电压不能突变，所以)输出端的电压将产生大小等于 VIN 的变化，使放大器输入端维持输入失调电压，即当开关 S1 从位置 2 拨到位置 1 时，输出端电压将从(VOS + IbiasR2)变为(VIN + IbiasR2)。S1 处于位置 2 时，放大器的偏置电流是由输出端经电阻 R2 提供的，当 S1 转向位置 1 时则由 C2 提供。R3 的作用是降低输出失调电压，如果要求放大器具有最大的线性范围，或者采用直流耦合，就应该使用该电容。

Initially the following measures are taken for association of the angle positions to physical reflectors, and for determination of the position of the vehicle (10): i at least three angle values with a suitable distribution over the search sector is selected, ii the angle values are associated to reflectors and a position is determined for the vehicle on the basis of the known position of the assumed reflectors, iii if the vehicle position determined in this way is within a certain part of the transport area the other angle values are associated to reflectors, iv for each angle value, existing deviation is determined between detected angle values and angle values expected between the vehicle position and known reflectors, v the measures taken are repeated for each possible combination of selected angle values.

最初使用下列步骤使这些角位与反射器关联以便确定车辆（10）的位置：i）在该搜索扇形上选择至少三个合适分布的角度值，ii）使各角度值与各反射器关联，根据假设反射器的已知位置确定车辆的位置，iii）如果如此确定的车辆位置在该运输区的某一部分中，则使其他角度值与反射器关联，iv）对于每一角度值，确定所检测角度值与车辆位置与己知反射器之间预期角度值之间的偏差，v）对于所选择的角度值的每一种可能组合反复进行这些步骤。

In the process of laboratory study, oxycodone was prepared by oxidating thebaine at 6,14-position under oxydol, hydrodeoxidizing 7,8-position double bond and 14-position ether under palladium catalyst. Furthermore, N-methyl of oxycodone was isolated byα-chloro-ethyl chloroformate under anhydrous condition and protection of 14-position hydroxyl to obtain noroxycodone, which was further converted into methylnaltrexone by N-alkylation in presence of cyclopropyl bromomethane, then by isolating 3-position methyl of methylnaltrexone under boron tribromide, becoming hydrochloride to prepare target compound, natrexone hydrochloride.

实验室工艺方面，本文首先用双氧水氧化蒂巴因的6-位和14-位、在钯炭催化下加氢还原7-8位双键和14-位醚合成羟考酮，然后提出并优化了在无水和14-位保护的情况下，用氯甲酸-α-氯乙酯脱去羟考酮的N-位甲基合成去甲羟考酮，再用环丙甲基溴将去甲羟考酮的N-位烷基化合成甲基纳曲酮，最后采用三溴化硼脱去甲基纳曲酮的3-位甲基和成盐酸盐合成盐酸纳曲酮。

In the Xizhou dynasty to Xihan dynasty ,the physician's position was inferior than that of witch physician though they already had high social position. From the mid of Xihan dynasty to Tang dynasty, the physician's position is markedly went down and caused the negative influence to the development of medicine as Confucianism became the orthodox ideology of the feudal society. From Song dynasty to Yuan dynasty ,the dynasts paid high attention to medicine ,so the physician's social position was greatly upgraded ,which promoted the development of medicine . The position of physician in the Ming dynasty and Qing dynasty were unprecedentedly debased. It became a very negative factor to the development of medicine.

经过本课题研究认为：医生的职责在夏至西周时期是由巫医兼任的，巫医在当时有着极其显要的社会地位，并在一定程度上对医学的发展作出了相应的贡献；东周至西汉前期，随着医巫的分离，医生的社会地位较巫医有所下降，但仍有相当的地位，并且活动相对自由；西汉中期以后至唐五代，随着儒家思想成为封建社会的正统思想，这一时期医生地位明显下降，对医学的发展产生了消极的影响；宋金元统治者重视医学，医生社会地位大为提高，推动了此期医学的发展；明清时期医生社会地位空前下降，是这一时期医学发展的一个消极因素。
