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。

Section 1 discusses the advantages of medical film printer and USB, and put forward one elementary design scheme of the system. The principle of laser printer and the holistic design scheme of system are presented detailedly in Section 2, while Section 3 expounds the technology of USB. Section 4 discusses design scheme of transfer system of the laser printer - includes the development of USB device and CPLD. The test of holistic laser printer and effect picture of medical image are presented in Section5. In the end, a review of this system and some bugs are put forwards at present.

First,the envelope rectangles set was obtained by equiangular rotation the initial envelope rectangle, and the periphery polygon was constructed by calculating the intersection points between the corresponding edges of the envelope rectangles set.

首先利用等角度旋转方法求得封闭曲线的包络矩形集，利用矩形集对应边的交点得到曲线的外包多边形。

Under normal temperature.the Ca2+-ATPase activity was found on the innerside of the PM.on the vacuole envelope and the chloroplast envelope,and theenzyme activity declined upon heat stress.The Ca2+-ATPase activity on the vacuoleenvelope,PM.and the chloroplast envelope in both Ca2+-and oxalate-treated peppermesophyll cells was higher than that in the control under the same condition.TheCa2+-ATPase was also found at the granum lamella,and it was activatedsignificantly by exogenous Ca2+ and oxalate treatments.Under heat stress.the Ca2+-ATPase activity declined slowly in both Ca2+- and oxalate-treated mesophyll cells.But La3+ treatment inhibited the enzyme activity under both normal condition andheat stress.

常温下生长的叶肉细胞，在质膜、液泡膜、叶绿体被膜等处有Ca2+-ATPase活性，热胁迫后酶活性下降；外源Ca2+和草酸预处理对辣椒叶肉细胞各种膜上Ca2+-ATPase活性具有促进作用，特别是定位于液泡膜、质膜和叶绿体被膜上的酶活性明显比对照提高；在叶绿体基粒和基质片层上也有酶活性，并且Ca2+和草酸预处理对该部位上的酶活性激活作用更明显；La3+处理的作用与Ca2+和草酸处理的效果相反。

But with its variety and specialization , three-axial non-instaneous envelope method had not meet needs. So four-axial non -instaneous envelope method was set forth firstly in this article, which is based on three-axial non-instaneous envelope and spiral rod compressor rotator speciality.

然而随着螺杆应用范围的扩展，螺杆型线不断复杂化、多样化，三自由度无瞬心包络铣削法已不能满足部分型线的加工要求，为此本文在三自由度无瞬心包络铣削法的基础上，针对螺杆压缩机阴阳转子的特性，在国内首次提出四自由度无瞬心包络铣削螺旋曲面的新方法，赶超国际螺旋曲面加工技术水平，具有重要的理论和现实意义。

In the past, the high frequency resonance technique is usually applied in the envelope detection for a vibration signal with amplitude modulation. When applying the Hilbert transform in the high frequency resonance technique for the envelope detection of vibration signals, the computing burden is very high. On the other hand, when applying the linear least squares analysis method, the computing burden is lower. When applying the envelope detection in the lowest vibration mode, an accelerometer with the low-pass filtering cutoff frequency at 4kHz should be choose.

在过去的研究方法中，振动讯号之振幅调变通常以高频解调分析法应用於包络讯号侦测，而高频解调方法应用希尔伯特转换的包络分析，所需要的计算量是非常的高，若以线性最小平方分析法应用於高频解调分析法中，则所需要的计算量较小，如果以最低模态来估测包络讯号时，可以适当的选取加速规来代替低通滤波器，而加速规的截止频带必须在4kHz左右。

This work produced large amounts of high-purity envelope protein antigens and envelope-specific antisera, and established detection systems for envelope antigens as well as antibodies.
