Machine of concealed source sex turns a sex pneumonic is one kind a qualitative sex that names with clinical pathology is pneumonic, COP was 1985 Epler [the pathology performance that 1] offers is pulmonary alveolus inside, fine bronchus of sex of alveolar canal, breath and eventually the independent disease that end fine bronchus has granulation organization to form inside antrum is planted, say to send a gender especially again machine of fine bronchitic companion turns out-of-the-way sex the gender is pneumonic , will nearly 20 years report gradually grow in quantity, easy infection, n/med tuberculosis, tumour, as nodal as lung disease, other a disease of qualitative sex lung promiscuous, reached my courtyard to received vivid check of treated bronchus lens lung 2008 2007 now (8 case that TBLB) wins pathology to confirm are analysed as follows.

概要： 隐源性机化性肺炎是一类以临床病理命名的间质性肺炎，COP是1985年Epler等[1]提出的病理表现为肺泡内、肺泡管、呼吸性细支气管及终末细支气管腔内有肉芽组织形成的独立病种，又称特发性闭塞性细支气管炎伴机化性肺炎，近20年来报道逐渐增多，易和肺部感染、结核、肿瘤、结节病、其他间质性肺疾病等混淆，现将我院2007年至2008年收治的支气管镜肺活检获得病理证实的8例病例分析如下。

Incorrectly low external cartridges will speed up the formation of a bubble ink chamber, even using the original cartridge of EPSON CISS, the same will happen over failure.

错误地将外置墨盒放低同样会加速墨腔泡沫的形成，即使使用了 EPSON 原装墨盒的连续供墨系统，同样会发生以上故障。

Described is a chemical feeder comprising a housing having a base and upwardly extending side walls that define a cavity for containing solid chemical material, e.g., calcium hypochlorite.

化学品输送器具有一个壳体（10），其上有一底件（12）和向上延伸的侧壁（14），形成一个空腔（8）可容纳固体化学材料如次氯酸钙。

In the paper, the simulation model of port plate/cylinder block frictional pair in which the lubricating film forms was established according to force balance equation and flow continuity equation with SIMULINK of MATLAB. The frictional pair includes of damp groove type continuous oil supply port plate /cylinder block frictional pair and semi-perimeter double oil groove type periodical oil supply port plate /cylinder block frictional pair.

本文根据配流副数学模型中的力平衡动态方程和流量连续方程，利用数学仿真软件MATLAB中的SIMULINK工具包分别对阻尼槽型连续供油配流副和半周槽双油腔间歇供油配流副建立了润滑膜形成的仿真模型，并对不同工况下的这两种配流副润滑膜的形成及变化规律进行动态仿真研究。

The binding of different halide anions to four strapped calix[4]pyrroles was studied by means of molecular mechanics and molecular dynamics simulations methods. The results indicate that the anion binding ability of calix[4]pyrrole-type systems could be effectively tuned by modifying the length and nature of the bridging straps. In this process, it was the most stable conformation upon anion binding due to the formation of four NH\|halide hydrogen bond, simultaneity, the difference of cavity by modifying straps adapted themselves to different halide anion.

模拟结果表明，加入带状修饰链和调节链长可以增强对某种特殊卤素阴离子的识别，在这个过程中，卤素阴离子与杯[4]吡咯NH上的氢形成的多氢键使主体分子与阴离子形成稳定复合物，同时带状修饰链通过改变杯吡咯空腔大小影响主体分子与卤素阴离子的氢键相互作用，从而调节了对不同阴离子的识别能力。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
