筛

Later on,the opened sieve plate was formed because of callose autolyzing after the protoplasm disappeared completely.Ultimately,the physiological function of SE was lost.

在筛管原生质完全降解消失后，筛板处的胼胝质自溶，最后形成具开放筛孔的筛板，至此筛管完全失去功能。

The process of preparing sterilizing granule capable of generating chorine dioxide in one package includes the following steps: preparing activating agent; mixing inorganic salt and nickel acetate, re-crystallization, sieving and deactivation; sieving and deactivating solid acid; mixing with inorganic salt; mixing sodium chlorite and cobaltous chloride, re-crystallization, sieving and deactivation; and mixing the activating agent with sodium chlorite.

一种可发生二氧化氯的一元包装消毒颗粒制备方法，其特征是制备活化剂：将无机盐加入醋酸镍，经过重结晶后，筛分、钝化处理；将固体酸进行筛分、钝化处理；然后与无机盐进行混合；在亚氯酸钠中加入氯化亚钴后，经过重结晶、筛分、钝化处理；将上述活化剂和亚氯酸钠均匀混合即成。

The kinematics parameters were firstly presented by establishing the mechanical model of relation between the vibration screen and particle to deduce periodicity condition of particle motion,then disturbing function of particle motion for periodic motion was educed by using Poincaré mapping method,and studied motion characteristics of particle in vibration screening in terms of numerical analysis.

利用振动筛与颗粒之间关系的运动学模型，导出颗粒运动的周期性条件；然后利用Poincaré映射方法，推导出颗粒的运动对周期运动的扰动方程；最后对振动筛分过程中颗粒运动特性进行了数值计算研究，得出了筛面上颗粒运动是经周期分叉和概周期分叉通向混沌的演化过程。

These data on ethmoid roof and cribrum should benefit the endoscopic sinus surgery and transnasal ethmoidectomy.

了解筛顶板及筛板的影像解剖对进行鼻内筛窦手术重要指导作用。

Coronal and sagittal images of ethmoid sinus were reconstructed with three - dimensional software in GE workstation.

结果：筛窦常见的解剖变异有5种：筛大泡占52％，Onodi气房21％，眶下气房5％，筛凹低位4％，纸样板过度内移7％。

The matrix differential equation is solved using method of steps and applying Laplace transform. Using this method and exact solution of the matrix differential equation with delayed arguments was....

待流场达稳态后，於注水井筛段注入追踪剂并在抽水井筛段量测浓度穿透曲线，使用适当数学模式分析其浓度穿透曲线及上、下井筛段泄降差，即可同时。。。。

The cortical cells had thin walls and mitochondrium, and nucleus wassurrounded by chloroplasts, and vesicles were next to cell plasmalemma. However, cellwalls of velamen, cortex and exodermis in the mycorrhiza of D. nobile had ring orpapillary thickenings in many cases. The hyphae were surrounded by moremitochondria and vesicles of plant, and the hyphae were digested and their structure waschanged at last. The cell wall of endodermis also had typical ring thickenings, and manysieve orifices in sieve tube elements of phloem were covered by callose, while therewere liaison cords in a few sieve orifices.

金钗石斛菌根的根被细胞的细胞壁多处出现环形圈，外皮层细胞壁加厚，木质化，也有环形圈存在，皮层细胞细胞壁多角形明显，加厚，皮层细胞中存在被消化、失去结构的真菌菌丝，在菌丝周围有较多的线粒体、小泡，内皮层细胞的细胞壁呈现的典型的加厚及木质化环形圈，韧皮部筛管的筛板结构，绝大多数筛孔已为胼胝质所覆盖，仅个别筛孔中还存在连络索。

Aimed at the low screening efficiency of Aiyou Coal Preparation Plant,some technical reforms were done,namely,proper coal feed rate,fitting position of feed trough and regular analysis of screening efficiency ,and the screening efficiency was obviously increased.

针对艾友矿选煤厂筛分效率低的问题，采取制定合理给煤量、合理布置筛网、合理布置给料溜槽和定期取样分析筛分效率等技术措施，使筛分效率得到明显提高。

If a sifter is made to fit in the bottom of the mealworm container, the frass will fall through the sifter, making it easier to clean the container.

筛选机 ：你可以作筛与8号（ 1 / 8 ）的硬体布或尼龙钢筋屏幕上发布木制框，如果筛是装在底部的mealworm集装箱， frass将下降通过筛，使它更容易清洁货柜。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
