Also, some patients with chronic hepatitis B have widely fluctuating HBV DNA levels that may vary from undetectable to 2,000,000 IU/ml.117 Thus, serial monitoring of HBV DNA levels is more important than any single arbitrary cutoff value in prognostication and in determining the need for treatment.

而且，许多患有慢性乙型肝炎的患者，HBV DNA水平波动的幅度很大，可从测不出到10'7copies/ml之间变动。因此，为了预测病情和确定是否有治疗需要，对HBV DNA水平的连续检测比任何武断确定的单个临界值更为重要。

Based on the ratio of the minerals, the team reports in tomorrow's issue of Nature that CO2 levels during the Archean could have been no higher than about 1000 parts per million—about three times the current level of 387 ppm and not high enough to compensate for the weak sun.

根据两种矿物的比例，研究小组在明天出版的《自然》杂志上报道说：在太古代期间，二氧化碳的水平决不会高于大约百万分之一千（1000ppm）——大约三倍于目前的水平（387ppm），不足以弥补阳光的弱势。

Results(1) Insulin secretion and mRNA levels of PDX1 were significantly decreased in rats with Type 2 diabetes meilitus compared with the control group.(2) Compared with the diabetic group, insulin secretion and mRNA levels of PDX1 were significantly increased in the medium and high dose of arecoline groups.

结果：（1）高糖作用引起Wistar大鼠胰腺β细胞PDX1 及胰岛素mRNA 的表达水平显著下降（P＜0.01）；（2）1 mg/kg和5 mg/kg槟榔碱处理能显著上调高糖喂养Wistar大鼠胰腺β细胞PDX1与胰岛素mRNA表达水平（P＜0.05，P＜0.01）。

By means of simulation, the authors research the over-voltage level at AC and DC sides of converter station as well as arrestor operation condition caused by last breaker trip occurred in inverter station of UHVDC power transmission project from Yunnan to Guangdong; analyze and reveal the interrelations among over-voltage level, various operation conditions and different action delay of DC protections and propose the requirement to the time of protection coordination to ensure secure and reliable operation of equipments for the project.

文章对云广特高压直流系统逆变站最后断路器跳闸引起的换流站交直流侧过电压水平以及避雷器工况进行仿真研究，分析揭示不同运行工况、不同直流保护动作延时与过电压水平的相互关系，提出对保护配合时间的要求，以确保系统设备能安全可靠运行。

In other words, the government controls the development of a lower price, for example, 3,000 yuan / square meters, the cost is lower than the price level of the developers of course have nothing to say, the cost is higher than the price level of the developer will stand up and tell the truth, reported that the true cost of their own, and then, on the basis of the average cost of developers, coupled with an average profit to arrive at a control price.

换句话说，政府控制的发展，以较低的价格，例如， 3000元/平方米，低于成本的价格水平的开发商当然无话可说，成本高于价格水平开发商会站起来，说实话，报告说，真正的成本自己，然后，根据平均成本的开发，加上平均利润为达成一项控制价格。
