First, based on the measurements of absorption cross-section, the absorption characters of the main polluted gases in flue gas were deeply studied, and found that SO_2、 NO、 NO_2、 NH_3 had a character of approximate periods absorption at some wave band, which is a good chance of a new measurement introduced. Secondly, the factors about absorption cross-section of the gases measured, which affect on the measurement precision of DOAS, is studied deeply. The influence of pressure and temperature on absorption cross-section was given special research, and the compensated measures were given to the gases based on the character of the gases. Thirdly, in practical measurement, it must have been satisfied that the monochromator was consisted with the reference spectrum, which was based on absorption cross-section. In order to satisfy the consistency, the technique of reversion in the image was introduced, the reversions of spectrums were realized with wiener filter and noise elimination based on wavelet transform.

首先从吸收截面的测量入手，对烟气中主要的污染气体SO_2、NO、NO_2、NH_3的吸收特性进行详细研究，发现这些气体在局部区域具有准周期吸收特征，这为引入新的测量方法提供了契机；其次，对决定DOAS测量精度的被测气体吸收截面的诸多问题进行了深入研究，重点研究了压力、温度对被测气体吸收截面的影响，并针对被测气体的特征提出了相应的修正措施；再次，在实际测量中，要求所使用的光谱仪必须与以吸收截面为基础的参考光谱相匹配，为了满足匹配这一条件，文中将图像复原技术引入到光谱复原，使用维纳滤波和小波消噪实现了光谱的复原，将复原后的光谱与所使用光谱仪的仪器函数卷积，即可实现；最后，在对DOAS测量原理详细分析的基础上，对传统的最小二乘—差分吸收光谱法进行了详细的阐述，通过实验证实两点：1。

The marginal division was a flat fan-shaped structure with a volume of (0.48±0.02) mm3, a maximum rostral-caudate axis of 1.6 mm, a maximum dorsal-ventral axis of 2.158 mm, and a widest axis (the diameter at lateral-medial coronal brain section) of 0.17 mm. The marginal division also moved progressively externally from the rostral section to the caudate section, but its scope was larger than that of others. The whole marginal division changed evenly from the rostral section to the caudate one. Its flat structure widened progressively and its dorsal-ventral diameter narrowed gradually and became plate-shaped.

边缘区呈现一个片状扇形结构，体积为(0.48±0.02) mm3，最大嘴尾径为1.6 mm，最大背腹径为2.158 mm，最大内外径为0.17 mm；同尾壳核和苍白球一样从嘴侧到尾侧随着脑平面的增宽边缘区亦逐渐向外侧移位，其移位的幅度亦明显大于脑平面增宽的幅度；整个边缘区从嘴侧到尾侧呈均匀变化，其片状逐渐变宽，长度逐渐变小，从而形成一个盘状结构。

纸机的清洗包括流送部、网部、压榨部、施胶部、干燥部等部分。

On 6, 7, two days, mainly from the short plate and do more, the outflow of funds in the banking section of the main plate, and coking coal plates, steel plates, Transport logistics plate; inflow of funds into the main plate is the real estate section, communications section; In addition, the Fund in the past two days, so the band is the main section of the Securities Insurance plate.

10月6日，7日两天，主要是从短期板，做更多的工作，在主要板块银行流出的部分资金，焦煤板块，钢铁板块，运输物流板块；流入资金流入的主要板块是房地产部分，通信部分；此外，在过去两天基金，以便乐队是证券保险板块的主要部分。

Data and bss define the section to be a data section, analogously to code. Data sections are marked as readable and writable, but not executable. data declares an initialised data section, whereas bss declares an uninitialised data section.

data和bss定义一个数据段，类似code，数据段被标识为可读可写，但不可执行，data定义一个被初始化过的数据段，bss定义一个未初始化的数据段。

For the all classes of dies, if we analyse the fluctuate, tendency of increase and decrease and law which appeared in the die's whole life, we will find that the master of the error are changeless; the error that because the abrade of the cutter and impression will be as the cutter grinding times increased at the same time.

新冲模在指定的冲压设备上投入使用至失效报废的整个寿命过程中，其合格冲件误差的主导部分固定不变即所谓固定误差。其大小就是新冲模第一次刃磨前冲制的合格冲件的偏差，也即冲模的初始误差，而此时的冲模具有初始冲压精度。

For the all classes of dies, if we analyse the fluctuate, tendency of increase and decrease and law which appeared in the die's whole life, we will find that the master of the error are changeless; the error that because the abrade of the cutter and impression will be as the cutter grinding times increased at the same time. And that will cause the error oversize gradually; and also have another part error are unconventional , unforeseen.

对各类冲模冲件误差在冲模整个寿命中出现的波动、增减趋向及规律等进行全面分析便可发现：冲件误差的主导部分是不变的；因刃口或型腔的自然磨损而出现的误差增量随冲模刃磨冲数增加而使这部分误差逐渐加大；还有部分误差的增量是非常规的、不可预见的。

First the math theory of machining simulation is studied, and the set structure of NC machining simulation system whose components, including time, input, output and so on, are defined. Hereby we set up the hierarchy structure, the logical structure, the static model and the dynamic model of simulation system. The construction method of sweep entity of cutter and rotation parts is researched, and their differential geometry invariants are calculated. NC code is unscrambled, and the recursion division arithmetic of time segment is put forward, which is the driven data of the movement or rotation parts. The CLDATA should be interference-free. To examine if there is interference between cutter flank and the work piece, an arithmetic that discussed the existence of intersecting curve between them is put forward.
