激光

For laser use in pulp capping and pulpotomy, an appropriate parameter must be selected. If the laser energy is too strong, the treatment will be unsuccessful.

为了能使激光应用于盖髓术和切髓术，必须选择合适的参数，因为如果激光能量太强，治疗就不会成功。

Thus endodontic treatment of choice comprises pulpotomy and subsequent dressing with calcium hydroxide.

如果能在此过程中使用激光，因激光具有蒸发凝固并封闭小血管的作用，则易形成无血的区域，治疗伤口表面，同时达到消毒的目的。

Methods:Pulpotomy and pulsed Nd∶YAG laser irradiation with different energy and exposure time on the exposed pulp tissues were performed in 3 dogs.

一组对照，一组切髓后激光照射断面，条件40Hz、60mJ(2.4W)，另一组切髓后激光照射断面，条件为40Hz、40mJ(1.6W)。各组均用盖髓剂盖髓。

Methods 230 cases of lacrimal duct obstruction with chronic dacryocystitis divided randomly into two groups.90 cases in group 1 were given operation of laser assisted dacryocytoplasty combining local drug remedy after dashing out the pyoid secretion at once,140 cases in group 2 were not only dashed out the pyoid secretion but also given antibacterial drug, then given operation of laser assisted dacryocytoplasty combining local drug remedy after inflammation was stable. All cases were callback after a week, and followed up more than 6 months.

方法随机选择230名患有慢性泪囊炎泪道阻塞的患者分为两组。1组90名患者冲出脓性分泌物后马上行泪道激光手术联合局部药物治疗，2组140名患者不仅冲出脓性分泌物，且加强抗感染，炎症稳定后再行泪道激光手术联合局部药物治疗，一周后复查，观察两组疗效，追踪半年以上。

We think the hydrophobic force in water is the main reason for nanoparticle reassociation, and it can decrease the production efficiency. 3. Under the fluence of 50, 120 and 200mJ/cm〓 the VOPc nanoparticles have been prepared by laser irradiation.

在对酞菁氧钒纳米颗粒的制备中，发现过长时间的激光照射并不能继续提高纳米颗粒的产量，溶液在低温环境下进行激光消融更有助于提高纳米颗粒的制备效率。

Four laser beams used for ~ 40 K and ~ 87 Rb cooling and repump lights are obtained by using acoustic optic modulators to offset the frequencies from the three external cavity diode lasers.

三台ECDL通过声光调制器产生四束光，分别作为40K和87Rb原子的冷却光和再抽运光，四束不同频率成分的激光分别注入锁定四台从激光器，然后Rb冷却光、K冷却光和K再抽运光再同时注入半导体激光放大器进行放大。

The Laser 350C combines the Cartes laser cutting system with the practicality and compactness of an integrated unwinder and rewinder.

激光350C智能卡相结合的激光切割系统的实用性和简洁的综合unwinder和复卷机。

The results indicated that:1. The temperature of dry and wet seeds rosed to different extent after irradiated by He-Ne laser with power density 3.5mW·mm~(-2) or CO_2 laser with power density 6.62mW·mm~(-2) correspondingly.

结果如下： 1。以功率密度为3.05mW·mm~(-2)的He-Ne激光和6.62mW·mm~(-2)的CO_2激光分别照射不同时间后，小麦种子都有不同程度的温度升高。

In this paper, the threshold behaviours of the self-pulsing instability for the class B lasers with saturable absorber are studied.

对含有可饱和吸收体的B类激光系统的自脉冲不稳定性的阈值行为进行了研究，并就各种激光参量对其阈值的影响进行了数值计算。

It has manifested originality、scientificalness and practicability of the reseach and may supply the correlation research too.

在研究过程中，我们自行设计了简易激光照射装置，并采用了照射菌膜的激光方法，体现了本研究的创新性、科学性和实用性，可供相关研究借鉴。
