The system is designed such that it can be operated by its own and has the advantage of fast ice making.

本海水液体冰制冰机器则是利用抽水马达抽水，经过冰筒冷却，将内部的水降温后使用冰刀将冰由冰筒下方往上推动，再将其刮出后再回到原来的容器，一直循环到完成结冰为止。

This article describes the application of the pipe-use ultrasonic anti-scaling device in the interstage cooler of the centrifugal air compressor.

针对这种情况，在压缩机循环冷却水入口处安装TC-2-20型高温高声强超声波管道防垢器，进行在线防垢除垢，达到了较好的防垢除垢效果，安装前，压缩机级间冷却器1a清洗2～3次，安装后1a只需清洗1次；同时还起到了一定的强化换热作用，安装后，压缩机二、三级气体入口温度平均下降了2～3℃。

They are "living predicaments","fuses of self-injury","triggers for self-injurious behaviors","positive perception after self-injury", and "interpretation after self-injury". The positive perception after self-injury and subjective interpretation would lead to "habitual self-injurious behaviors". Therefore, they become a circular pattern of adolescents' self-injurious behaviors.

研究结果显示，青少年自伤经验之发展历程：包括「生活困境」、「自伤导火线」、「引发自伤行为」、「转化情绪」、「自伤后的主观诠释」五个阶段，且自伤青少年在自伤后的情绪转化及主观诠释会引发「习惯性自伤行为」，而形成一循环模式。

Portal vein pressure, size of spleen the collateral circulation of portal vein and the fluctuation of hematocyte counts were measured and recorded at the preconcerted time.

实验犬25只，随机分为A组(正常组，n=5)、B组(对照组，n=10)、C组(实验组，n=10)。A组仅予以剖腹探查，B组予以门静脉主干部分结扎建立模型，C组则通过门静脉主干部分结扎附加3周后脾静脉缩窄及其属支结扎的方法建立模型，建模后术前及术后每周动态观察两组动物血象的变化，B、C组在预定时间点(术后第5、第9周)分别随机选择5只动物开腹观测门静脉自由压、脾脏大小、门体侧支循环形成情况，并切取脾脏行组织病理学检查，此外，术前及术后预定时间点了解骨髓增生情况变化。

METHODS: Saliva and serum samples of 5 infected, 7 reinfected and 8 treated rabbits were collected at different times periods. The CAb in saliva and serum was detected by using ELISA.

建立血吸虫兔感染模型，收集感染后不同时期、再感染及治疗后不同时期的唾液和血清，用ELISA 检测其中的循环抗体及其效价，并将检测结果加以比较。

Its working principle is conducting oil in the heater after heating oil transported to the various thermal equipment, heat transfer through after and then back to the furnace to form a closed circle of the process of compulsory in order to achieve the purpose of heating.

其工作原理是导热油在炉内加温后用油泵输送到各个用热设备，经过传热后再回到炉内，形成封闭的强制循环过程，以达到加热目的。

In accord with the promotion in the photosynthetic oxygen evolution and ATP content, the transient increase in chlorophyll fluorescence after the termination of actinic light was increased; and meanwhile, the half-time of re-reduction of P700〓 in the presence of DCMU after a pulse light under background far-red light was shortened by approximately 30%, indicating that cyclic electron flow around PS1 was accelerated by the treatment.

与此同时，我们还发现经NaHSO〓处理后，蓝藻细胞的作用光关闭后叶绿素荧光瞬时上升的幅度增加，同时在远红光背景下和DCMU存在时，饱和闪光后蓝藻细胞P700〓再还原的半时间缩短约30％，表明低浓度NaHSO〓溶液处理能够促进蓝藻细胞围绕PSI的循环电子传递。

The temperature of flue gas out of air preheater in boiler is normally about 120～180℃, the flue gas enter the absorb tower from the bottom via pre-deduster and is accelerated by venturi tube at the bottom of absorb tower, then is taken to circulating fluid bed. The materials are in the circulating fluid bed, due to the effect of flow, the gas-phase and solid-phase generate fierce turbulence and combination and are fully contacted, then form polymers constantly during the ascending and return downward, while the polymers are constantly disassembled during fierce turbulence and elevated by airflow, which makes the slip velocity between gas and solid reach the tenfold times of single slip velocity.

首先从锅炉的空气预热器出来的烟气温度一般为120～180℃左右，通过预除尘器后从底部进入吸收塔，然后烟气通过吸收塔底部的文丘里管的加速，进入循环流化床，物料在循环流化床里，气固两相由于气流的作用，产生激烈的湍动与混合，充分接触，在上升的过程中，不断形成聚团物向下返回，而聚团物在激烈湍动中又不断解体重新被气流提升，使得气固间的滑移速度高达单颗粒滑移速度的数十倍。

Associated with the steam corrosion of Hebei some certain power plant circulating water pump,after analyzed the main reasons of circulating water pump steam corrosion ,brought forwards the effective measures of this problem,to offer the basis of economic safe operation of the power plant.

结合河北某电厂循环水泵的汽蚀情况，在充分分析了循环水泵汽蚀的主要原因后，提出了解决问题的措施，为电厂的经济安全运行打下了良好的基础。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
