Thin-wall box structures are applied widely in long-span or mid-span bridges and it is difficult to calculated box beams.

大中跨预应力混凝土桥梁工程中广泛采用的箱形截面，其薄壁效应成为计算中的难点。

Keeping Green Lacertas outdoors in the mid-northern US requires that they be able to dig deep enough for hibernation, and that in winter the terraria are protected from excessive rainfall so that the hibernating animals will not drown under ground.

在美国中、北部的户外饲养捷蜥，需要能让它们挖至地底足够深的地方进行冬眠的环境。并且在冬季需要防止捷蜥冬眠的地方被雨水淹没导致冬眠中的捷蜥淹死（这点在室内饲养就不必担心了，只要别倒水进饲养箱就行）。

采用与土木工程施工特点相适应的传感器安装工艺与保护方法，将光纤B ragg 光栅埋于正在建设的呼兰河大桥预应力箱梁中，测量了预应力张拉过程中混凝土结构内部的应变变化。

Large air separation plant 40000m3/h, This plant adopts molecular sieve system to adsorb CO2, C2H2, moisture and CnHm in air to pre-purify air, by use of air booster compressor, to pressurize some of purified feed air by two sections, pressurized air to warm up high pressure liquid oxygen in high pressure coil heat exchanger to ambient temperature and delivere out off cold box to coal gasification, some pressurizrd air by first section is drawn from middle part of coil heat exchanger and expanded in medium pressure expander then led into lower column, other part of pressurized air by second section is drawn from cold end of coil heat exchanger and led into lower column after throttling, un-pressurized feed air is cooled by return gas in plate fin heat exchanger and led into lower column.

产品描述：采用常温分子筛空气预净化系统吸附空气中的CO2、C2H2、水份和一些碳氢化合物，使用单独的空气增压压缩机将部分净化后的原料空气分为两段增压，增压后的空气在高压绕管式换热器中将经液氧泵加压的高压液氧汽化并复热至常温送出冷箱直接供煤气化工序使用，第一段增压后的空气，部分从绕管式换热器中部抽出经电机制动的中压透平膨胀机膨胀后送入下塔，另一部分经第二段增压后从绕管换热器的冷端抽出节流后送入下塔，未经增压的原料空气在板翅式换热器中被低压返流气体冷却后进入下塔。

Contrarily, I'd like to believe all of this has perhaps been mysteriously arranged by the God of our unseen world. Just like the puppet player, Alexander, who always prepared an alternative puppet in the event of an unforeseen accident, we just might catch Him during this show's performance.

我反倒更愿意相信这是上帝在冥冥之中的安排，就像那个表演木偶的亚历山大，为了防止木偶在&表演&的过程中发生损坏而措手不及，所以总有一个备用的静静地躺在道具箱中做B角。

B. comparison of vertical and horizontal butterfly valve in the large butterfly valve, the valve shaft there is the difference between vertical and horizontal, vertical butterfly valve casing is usually deep, debris in the water easily spiral shaft, affecting Kai closed; horizontal butterfly valves for variable speed gear box in the side near the valve well on the road account for the wide flat position, influence the arrangements of other pipelines.

b。立式与卧式蝶阀的比较在中、大型蝶阀中，过滤器阀轴存在立式与卧式的区别，通常立式蝶阀的覆土较深，水中杂物容易缠绕轴端，影响启闭；卧式蝶阀的变速传动箱在侧旁，阀井在道路上占的平面位置较宽，影响安排其它管线。

Commonly used white and other light-colored Shoushan stone, soak in nitrite iron [Fe (NO3) 2] solution, and then out to dry; also be directly used yellow, orange and light red Shoushan Stone carving, and placed in the shell fire or electric rice chaff box, temperature 3000C ±, about 12 ~ 30 hours, you can get red ocher ~ thick ocher.

通常使用白色及其他浅色寿山石雕，浸泡于亚硝酸铁[Fe(NO3)2]溶液中，然后取出使其干燥；也可直接用黄、橙和浅红色寿山石雕，置于稻糠壳炉火或电热箱中，恒温3000C±，约12~30小时，即可获得红赭~浓赭色。

When the oil level in the lower casing reaches the intermediate mark in the oil window (not stop feeding oil to the gear reducer from filter press), startup oil pump in the lubricating station to feed oil to lower casing. In order to assess the oil level in the upper casing, it is allowed to remove the plug screw of observation hole at thrust bearing oil sump in the upper casing.

较为方便的方法是拆除减速机箱体中分面法兰上的呼吸器，利用其安装孔对减速机下箱体进行加油，当减速机下箱中的油位到达后油窗中间刻线时（不停止滤油机对减速机的加油），可以启动润滑站油泵对减速机上箱体进行加油。

Encourage him/her to lighten the load in the school locker during the day.

在白天上课时，就把背包中的东西寄存在学校的存物箱中，以减轻背包的重量。

A development and fecundity study of the almond moth, Cadra cautella, reared on brown rice, pearl barley and Sue's artificial diet was conducted at 28±1℃ and 65±5% RH with a 12L: 12D photoperiod.

在28±1℃、65±5%RH及12L：12D光周期之定温箱中，分别以糙米、薏仁及苏氏人工育粉斑螟蛾Cadra cautella (Walker，比较其在同食物中之发育与繁殖情形。
