The amount of heat can be collected by heat pump technique and used in a circle. Under the floor or in the wall can be installed heat or cooling system without any change of the house shape. Some of architects like to design the greensward on the roof of house. But many people would rather to install Solar Water Heaters there.

地板、墙壁加热、制冷、房顶种草皮、更多的是在房顶安装太阳能热水器，热泵技术采集空气中分散的热量"为我所用"，过滤器可有效地收集空气中细小的尘埃，从而能够抑制霉菌等过敏生物繁殖。

The compound 117 is 19-fold more potent than -Hup A and 37-fold more potent than Tactine, its selectivity is 31-fold more potent than Tacrine.

其中化合物117的AChE抑制活性是石杉碱甲19倍、Tactine的37倍，其选择性也是Tacrine的31倍，可作为先导化合物进一步研究。

This system is designed based on SPCE 061A microcontroller to measure the close loop parameters of the amplifier. The system can measure the input offset voltage、the input offset current、the open loop AC differential mode voltage gain、the AC common mode rejection ratio and unit gain bandwidth,using the measure method of assistant amplifier. What is more, data printing is completed in this system.

摘要本系统是基于SPCE 061A 单片机的运算放大器闭环参数测试系统，该系统采用辅助运放测试方法，可对运放的输入失调电压、输入失调电流、交流差模开环电压增益和交流共模抑制比以及单位增益带宽进行测量，并具有将测试数据打印输出的功能。

Since both of the suppression on P5CS and PDH down regulated copper entry, the mechanism of blocking copper entry could be related to the utilization of proline instate of the proline level only.

由於抑制P5CS或PDH基因均可使脯胺酸的利用降低，显示铜逆境下脯胺酸的增加阻挡铜进入植体之机制，可能与脯胺酸含量无关而是与脯胺酸的利用有关。

To explore the influence of reticuloendotheliosis virus and subgroup J avian leucosis virus infection on chicken cellular immunity,the mitogenic response to ConA of blood and spleen lymphocytes tested and analyzed with 3H-thymidine(3H-TdR) incorporation assay at different intervals after infection or co-infection of single or both viruses.

自1974年分离出网状内皮增生症病毒[1]和1991年分离出禽白血病病毒J亚群[2]以来，在我国先后分离出不同毒株的REV和ALV-J，并开展了病原学、流行病学、致病性和免疫反应以及预防诊断等方面的研究，揭示出不同的致病性，并且确认它们都可造成感染鸡群免疫抑制，成为一些

And the rats in the control were executed at 5 months to observe the develope of pancreatic cancer by macrograph and microscopy, The EnVision TM immunohistochemistry was used to assay the expression of EZH 2 and PTEN in above pancreatic specimens.

较大剂量DMBA置入胰实质内可获得较高胰腺癌发生率，TSA能抑制胰腺癌的发生和生长；EZH 2基因的激活及PTEN基因的失活在大鼠胰腺癌发生中可能起关键作用。

This article introduced the antijamming in the NC system design,from the shield (including electric field shield ,magnetic screen and electromagnetic field shield ) designs mentions,added the absorbing circuit to the perceptual load to suppress the transient state noise to give the specify,might avoid the NC system which disturbed creates softly breakdown.

本文介绍了抗干扰在数控系统中的设计，从屏蔽(包括电场屏蔽、磁场屏蔽和电磁场屏蔽)设计谈起，对感性负载加吸收电路来抑制瞬态噪声做了详细说明，可避免干扰造成的数控系统的"软"故障。

The inhibition of Myostatin expression can accelerate the myoblast proliferation and myofibril hypertrophy, which results in the skeletal muscle hyperplasia.

对该基因表达的抑制可引起成肌细胞的过度增殖和肌纤维的肥大，从而引起骨骼肌增生。

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

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
