多变化的

For example if you had a clothes shop specifically for women you will want to only stock women's clothes which will allow you to get more styles and variations giving them more choices.

例如，如果您有一个服装店专门针对妇女的你会想只股票妇女的衣服，让您获得更多的款式和变化给他们更多的选择。

And this causes a frequency change Δf. The resonant point tracing algorithm describes how to detect Δf. So it can introduce a feedback frequencydifference -Δf through a closed loop to realize the resonant state o In the digitaldetection scenario, using staircase wave to replace saw tooth wave, it can overcome a lot of shortcomings in the analog system. The character of the staircase wave affects the detection precision directly. This thesis analyzes a high precision scenario producing a staircase waveform in detail. It can reduce the number of the bits in D/A converter greatly. This thesis proposes another method to improve the detection precision in case that the A/D converter has comparatively little number of bits, while this method will not increase the cost of the system greatly.

在谐振式光纤陀螺中，环形谐振腔的旋转使得谐振腔的谐振频率发生了变化，从而产生了一个与旋转速度成正比的频率变化值△f，谐振点跟踪算法描述了如何检测出△f，从而可以通过闭环在系统中引入反馈频差-△f，实现光路的谐振状态；在数字闭环检测方案中，用阶梯波作为反馈信号来代替锯齿波，可以克服原来模拟系统中锯齿波的很多缺点，阶梯波的性能直接影响着系统的测量精度，本论文详细分析了一种高精度阶梯波生成方案，使得所需D／A的位数大大降低；本文还分析了A／D转换器对系统测量精度的影响，提出了一种A／D转换器位数较少的情况下提高系统测量精度的措施，同时又不会增加太多的系统成本。

The content ofone liver protein band (R_f=0.79) at 1℃was significantly higher than at room temperature (P＜0.05).On the 2-D native-PAGE/SDS-PAGE gel, the content of P spot (MW=51kDa, R_1=0.47on the 1D native PAGE gel) at 1℃was significantly higher than at room temperature (P＜0.05), and the content of N spot (MW=65 kDa, R_f=0,94 on the 1D native PAGE gel) at roomtemperature was significantly higher than at 1℃. These protein spots may be related with the adaptation to the low temperature of the Heilongjiang wood frog.

黑龙江林蛙肝脏蛋白电泳显示，胶浓度6％的肝脏PAGE图谱分辨率高、谱带多，可分辨出15～19条谱带，其中1℃组R_f=0.79蛋白含量比室温组显著增加(P＜0.05)。2-D native-PAGE／SDS-PAGE电泳时，胶浓度为12％时分离效果较好，蛋白斑点较多。1℃组中P蛋白斑点(MW=51kDa，一向PAGE的R_f=0.47)显著性上调(P＜0.05)，N蛋白斑点(MW=65kDa，一向PAGE的R_f=0.94)显著性下调(P＜0.05)，推测这两种蛋白可能与黑龙江林蛙在低温环境下的适应性变化有关。

The manner of death was deduced comprehensively based on all above findings. Results: There were 85 cases determined as drug abuse death in Shaanxi area from Oct. 1995 to Oct. 2001, including 63 males and 22 females. 70% of the subjects detected in postmortem biological samples were heroin /morphine. Hyperaemia, edema, hemorrhage and arteriolar sclerosis of multi-organs; cells denature and necrosis; foreign body in pulmonary, as well as needle puncture tracks on skin and dermapostasis, were common pathological observations. Incidences of tuberculosis(21%),cirrhosis(12%) and hepatitis(9%) were higher than those found in general autopsy population. No AIDS case was found.

例如，Greenamyre和他的同事在2000年报道了经大鼠颈静脉慢性灌流鱼藤酮复制了帕金森病的主要特征，包括选择性黑质纹状体多巴胺系统变性，Lewy小体样细胞浆包涵体形成和一些行为变化，例如运动减少和僵直等。从发病机制上考虑，鱼藤酮诱导的多巴胺神经通路损伤被认为是由鱼藤酮抑制线粒体复合体Ⅰ活性引起的。

The results indicated that the typical apoptosis was induced by PRRSV in lungs and uteri. The ultrastructural changes showed different characterizations at different stages of the infection. During the early stage from 8th h to day 3 postinfection,the apoptosis cells shrank,the cytoplasm concentrated,the chromatin condensed,the kernel disaggregated and the endoplasmic reticulum dilated. During the middle stage from day 5 to day 9 postinfection,the apoptosis cells evidently shrank,the cell membranes protu berated,the plastosome manifolded,and apoptosis bodies were found. During the last stage from day 10 upwards postinfection,the apoptosis bodies degenerated and disappeared,and no inflammation occurred. Few apoptosis cells were necrotic.
