At high-frequency voltage, a transformer winding is equivalent to a linear, bilateral passive network which consists of linear resistance, capacitance and inductance. The equivalent model of a transformer winding in different frequency bands can be known by studying the bilateral network.

变压器绕组在较高频率的电压作用下，每个绕组本身均可视为一个由线性电阻、电容、电感等分布参数构成的无源线性双口网络，通过对该双口网络的研究可以得到变压器绕组在各个频段的等效模型。

In order to measure the passive network's conduction automatically, a network conduction instrumentation based on FPGA technology was designed and implemented according to the design principle of Virtual Instrument. System adopted FPGA technology building a digital flat-top to imitatively produce the high quality sine signal. Under the control of C8051MCU, measurement, calculation and display of the port network's conduction were automatic implementation. Furthermore, the system has the function of frequency step measurement.

摘 要：为了实现对无源端口网络的导纳进行自动测量，根据虚拟仪器设计思想，设计实现了基于FPGA的网络导纳测量仪，系统以FPGA作为数字平台模拟产生优质的正弦信号，在单片机C8051的控制和处理下，自动实现端口网络导纳值的测量、计算、显示，同时具有频率步进测量功能。

Because it influentes the masticate function seriously、affects the face shape and brings tremendous of sufferings, the patients request to be repaired urgently.

One, suck phlegmy the preparation before works 1 should make sure negative pressure attracts plant above all each conduit joins correct, close together, unobstructed, assure significant negative pressure, general adult 10.64~15.96Kpa, the baby should be controlled in 7.98~10.64Kpa. 2 preparation rinse the asepsis physiological saline that smokes phlegmy pipe 2 bottles, 1 bottle wash pump technically with Yu Chong the suction inside tracheal spile is phlegmy canal , additional 1 bottle rinse those who had sucked mouth, nasal cavity technically to smoke phlegmy pipe . 3 equipment are very different the asepsis of model sucks phlegmy canal and asepsis glove. 4 because suck phlegmy itself,be a kind of stimulation to the patient, sober patient is not willing to suck normally phlegmy, and the family member of insensible patient also thinks to suck phlegmy special anguish.

一、吸痰前的预备工作1首先要保证负压吸引装置各管道连接正确、紧密、通畅，保证有效的负压，一般成人10.64~15.96Kpa，婴儿应控制在7.98~10.64Kpa.2预备2瓶冲洗吸痰管的无菌生理盐水，1瓶专门用于冲洗抽吸气管插管内的吸痰管，另1瓶专门冲洗吸过口、鼻腔的吸痰管。3备好不同型号的无菌吸痰管及无菌手套。4由于吸痰本身对病人是一种刺激，清醒的病人通常不愿意吸痰，而昏迷病人的家属也认为吸痰非凡痛苦。

The differentiation states of costae indicates the ways they absorb and transport water, and their ability adapting to the dry conditions, which was elucidated by the following examples: Brachythecium plumosum, because of its thin cell-walls in the costae and the absence of hydrome, assistant and steroid cells, can absorb water and nutrition under shady and moist conditions; Plagiomnium rostratum, though often grows in shady and wet condition, has hydrome and steroid cells, a feature similar to those of xeric mosses, which endows it to grow in the conditions with periodical drought stress during its life cycle; Hygrohypnum luridum is characterized by its slender leaves with only one layer of cells, the thin cell-walls, the absence of filaments on the leaf surface, and the fewer layer cells in the costae, the absence of hydrome and steroid cells. These features make it adaptable to aquatic environments. For Pogonatum inflexum and Atrichum undulatum, their ventral surfaces covered with lamella, while for Racomitrium japonicum, Thuidium cymbifolium, Macromitrium ferriei, Diphyscium fulvifolium, Barbula unguiculata and Ceratodon purpureus, their leaves are strongly mammillose or papillos. Such appendiculate structures made them adaptable to thy conditions.

例如，荫湿生环境下的羽枝青藓Brachythecium plumosum，其中肋细胞胞壁较薄，无导水主细胞和副细胞的分化，也没有厚壁细胞分化，能够在阴湿环境下吸收水分和养分；钝叶匍灯藓Plagiomnium rostratum具有与旱生藓类植物相似的中肋结构，叶片较厚，中肋具导水主细胞，中肋背面具厚壁细胞，这些特点使该种藓类植物能够分布于间隙性干旱胁迫的环境中；水灰藓Hygrohypnum luridum叶片纤细柔弱，仅1层细胞，细胞胞壁薄，叶表无附属结构，中肋细胞层数少，无导水主细胞分化，也没有厚壁细胞，这些特点使得水灰藓'能够生长在水生环境中；东亚小金发藓Pogonatum inflerum和波叶仙鹤藓Atrichum undulatum的叶腹面覆盖着栉片，东亚砂藓Racomitrium japonicum、大羽藓Thuidium cymbifolium、福氏蓑藓Macromitrium ferriei、东亚短颈藓Diphyscium fuhifolium、扭口藓Barbula unguiculata和角齿藓Ceratodon purpureus的叶片表面有乳头状突起或疣状物，这些附属结构使它们能够适应于旱生的环境中。

Here's a reminder check your tims they probably say "made in china" don't make me get on this tip and straight kill ya his name is sterling cause all he rocks is silver dude, you, stop followin trends your girl must love alcohol cause she be swallowin' jin yo imma bout to flip the when it's comin' to it aye yo you see me spittin on the block you runnin to it this is 106 and park, i'm a hard act to follow you a amateur, you go to the apollo cause i'm freestyling know when i'm done son, you ain't a baller tell the audience the truth i saw him breakdancing for spare change on 40-deuce

你那靴子上写着&中国制造&呐让我一下抓住你这个错把你说得无语你那亮闪闪的银链子比你名字拉风多了我说哥们，别见样学样你的妞肯定喝高了，因为她正suckin jin's dick（就不写中文了，大伙都明白。呵呵）我走哪你跟哪我吐口痰你都狠不得过去舔两口这是在106 and park，想学我可不容易你要是个业余的就去apollo吧我正freestyle呢，孙子，好好听着就快完了跟观众说实话吧，你屁也不是我看见这孙子刚才跳霹雳舞了！
