However, the CMOS image sensors can provide stronger anti-radiation capacity than CCD as well as Single Chip Integrating with image sensors array, drive and control circuit, signal processing circuit, A/D conversion circuit and Completely Digital Interface Circuit. The CMOS image sensors also possess high quantum efficiency, wide spectral response, good response uniformity, low supply voltage and low request of clock. At the same time, the small bulk, high reliability, low power consumption and low cost are the prominent advantages of the CMOS image sensors too, thus CMOS image sensor has more exploiture foreground in X-ray real-time radioscopy imaging system.

由于CMOS 图像传感器比CCD 具有更强的抗辐射能力，还具有将图像传感器阵列、驱动和控制电路、信号处理电路、模数转换电路、全数字接口电路等实现单片集成以及量子效率高、光谱响应宽、响应均匀性好、工作电压低、对时钟脉冲要求低、体积小、重量轻、功耗低、高可靠、低成本等优点，因此在X 射线实时检测中更具有开发前景。

But they have done so by pushing prices down so that margins are razor-thin.

但它们的手段是压低价格，因此利润率极低。

Whether there was a correlation between the peak value at the elevated ST segment in infarction area and the valley value at the reciprocal depressed ST segment was mainly related to the time lasted for the restoration of depressed ST segment.

梗塞区ST段抬高的峰值与对应导联ST段谷值之间有无相关性主要与压低的ST段恢复时间有关，半月以内恢复者有显著相关性，半月以上恢复者则无相关性。

We used reduced Bethe-salpeter equation to study the properties of heavy flavor mesons at a finite temperature.

我们采用约化的Bethe-Salpeter方程讨论了重味介子在有限温度下的性质，并基于Charmonium谱的统计性质提出了J／Ψ压低的一种新的机制。

The government-oriented land reserve model has achieved some good results, but it is still going under way and some problems do exist, which can be listed as follows: 1 The legal rights of the people whose land has been purchased may be infringed upon because of the government's monopoly over the land purchase price; 2 Aimed at increasing land remise income, the local government reduces land supply for the purpose of raising land price, which arouses people's suspicion upon land reserve system. 3 The government-oriented land reserve model needs large funds and it is difficult to meet the demand for funds mainly by bank loans, which results in more risks in the operation of land reserse funds.

在肯定成效的同时，还应看到政府主导型土地储备模式还处在发展初期，实际工作中也遇到了一些问题：一是要求所有进入城市流转的土地必须由政府统一收购，容易引起地方政府利用垄断权利，压低土地收购价格，侵犯土地被收购者的合法权益；二是政府牢牢掌握城市土地供应的主动权，一切土地经由政府垄断供应，但由于土地供应与地方财政收入密切相关，为增加土地出让收益，地方政府采用"饥饿供地法"来达到提高土地价格的目的，引起了人们对土地储备制度的怀疑；三是政府主导型土地储备模式需要巨额资金加以支持，但以银行贷款为主的融资方式难以满足其资金需求，增加了土地储备资金运行的风险。

They told me they had to boil the rice in a pressure cooker.

他们说，这里气压低，做饭得用高压锅。

By late 2005, this battle had pushed rates for ropy borrowers down to a little over 7%.

到2005年后期，这场厮杀已经使对资信较差借款人的利率压低到了略高于7%的水平。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
