不变化地

I saw the earth mother wore a white sweat shirt, my brother trees are magically changed hairstyle, her sister is very finicky grass before more cold My God, she refused to come out of hiding at home.

我看到了大地母亲穿上了白色的绒衣，大树哥哥都神奇地变化了发型，小草妹妹十分娇气，才多冷的天呀，她便躲在家里不肯出来了。

Methods The mouse thymocyte model of apoptosis was induced by dexamethasone. The apoptosis ratio was observed with flow cytometry technique.

方法采取体外细胞培养 Balb/c小鼠(体质量 20 g左右的 Balb/c小鼠，雌雄不限)胸腺细胞的方法，制备地塞米松诱导的细胞凋亡模型，通过流式细胞仪观察凋亡细胞数量的变化情况。

These changes have come about not because human beings have suddenly and unaccountably improved, but because positive steps have been taken to change the present laws.

发生 这样的变化不是由于人一下子不可思议地变得好了起来，而是因为人们采取了积极的措施来改变现行法律。

From the tests,we have obtained some structural variant features related with salt resistance and demonstrated the successful introduction of Rhizophora apicularta DNA into tomato.This thesis contains two parts. In the first part,the morphological and anatomical structures of the leaves were investigated. As to the morphology,some difference between control and transformed tomato were found. The leaf dimensions of the transformed tomato with unextended leaves were smaller than that of control. These structure changes should help to decrease the evaporation of water effectively and release the physiological drought resulted from saline.

本实验分两部分：第一部分、对转化番茄的形态及细胞显微结构进行观察与分析，实验表明转化番茄形态与对照相比有明显的变化，其叶面积变小，叶形收拢，这种结构可有效地减少水分的蒸发，缓解由盐胁产生的生理干旱；组织解剖结构结果显示，耐盐番茄在细胞结构上发生了明显的变异：其气孔器倾向下陷，表皮毛增多，叶脉微管组织不发达，微管束周围出现增多的贮水细胞，叶缘及其它部位表面分化出大型的多细胞分泌型结构，这些结构与转化番茄后代较强的耐盐能力有关。

The fired nerves and the unfired nerves of PCNN corresponding to pixels of image are considered as target and the background respectively. The between-cluster variance between the target and the background is calculated at each process of iteration.

在PCNN中，具有相似输入的神经元同时发生脉冲，能够弥补输入数据的空间不连贯和幅度上的微小变化，从而较完整地保留图像的区域信息，这对图像分割无疑是非常有利的。

Grounded on the first chapter, new and original in content, the second and the third chapters, employing the theories in phonetics, writing, rhetoric, semantics and aesthetics, further discusses the rhetorical and the semantic functions of the comma in English and Chinese: rhetorically speaking, the comma can be used to clarify, to expound, to substitute, to emphasize, to contrast, to complement, or to vivify; semantically speaking, the comma itself can carry information to indicate certain meaning, or the presence and absence of the comma can cause semantic changes. The fourth chapter applies what has been discussed in the previous chapters to English-Chinese translation.

在此基础上，本文第二、三章标新立异，运用语音语调原理、写作、修辞、美学、语义学等方面的知识，通过详实的文献实例，全面地论述了英汉语逗号的修辞和语义功能：从修辞功能的角度看，逗号可以用以进行澄清、解释、替代、强调、对比、补充，或是取得生动和幽默的效果，等等；从语义功能的角度看，逗号本身可以作为信息载体，暗含特定的意思，在更多的情况下，它本身不含意义，但它的使用与否会引起整个句子意思的变化。

On the basis of analyzing the law of variation of the zero order current , the zero order voltage and the zero order power in the isolated neutral system, a synthetic criteria principle of selecting the grounded fault line according to three criterias at the same time was put forward.

在对中性点不接地系统单相接地故障情况下零序电流、零序电压以及零序功率的变化规律做了认真分析的基础上，提出了采用3个判据同时判断的故障选线三合一综合判据原理，这个综合判据可以大大提高接地选线的准确率，具有一定的推广利用价值。

Recently, people already do many research to shotdetection. But it still have many issue not to solve due to video peculiarity, such ashow to confirm the accurate translate frame, how to detect the amphibolous gradualshot translation, how to select suitable automatic threshold, those still have auniversal effectively method.

近年来人们已经对镜头检测做了大量的研究，但由于视频的特性，镜头检测中还有很多问题没能很好的解决，例如如何确定精确的镜头转换帧，如何检测变化不明显的渐变，如何自动地选取合适的自适应阈值都还没有一个通用有效的方法。

Thoracic surgery doesn't affect blood viscosity of patients. The anticoagulative drugs are not necessary to protect pulmonary embolism postoperation. We should select treatment according to the patients concrete conditions.

开胸手术后对血粘度变化的影响不大，对胸科手术病人预防术后发生肺动脉栓塞，不一定要常规地给予预防性抗凝等治疗，而应该根据病人具体情况考虑治疗方案。

The climatological behavior of the front cannot be reliably ascertained from just two years of monitoring.

仅仅从这两年的的监测来看，锋面的气候变化不能完全可靠地被确定下来。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
