Purpose: To compare the incidence and severity of all grades of dysphotopsia in three types of acrylic intraocular lenses: the Acrysof MA30 BA and MA60 BM IOLs (Alcon) and the Akreos Fit one-piece IOL (Bausch and Lomb). Methods: In all 111 patients were prospectively recruited who had undergone uncomplicated cataract surgery in the previous 12 months. Patients were assessed using a combination of a questionnaire and standardised provocation test, and were scored on a grading scale of 0-6 (0 indicating no glare and 6 indicating the most severe symptoms). Results: The overall incidence of dysphotopsia was 77.7%. Patients with absent or mild symptoms (scoring 2 or less on the grading scale) were greater in the group implanted with the Akreos IOLs (49/65 eyes, 75%) as opposed to (44/92 eyes, 48%) of the eyes implanted with Acrysof lenses. Patients with more marked symptoms of glare as judged by scores of 5-6 were uncommon, but more prevalent in the Acrysof lenses (12/92 eyes, 13%) compared to the Akreos lenses (3/65 eyes, 4.6%) respectively. statistically the Mann-Whitney test showed that therewas significantly less dysphotopsia with the Akreos lens when compared to the Acrysof MA30 (P=0.005) and MA60 lenses (P=0.002). Conclusion: This study demonstrates that dysphotopsia symptoms are commonly seen in certain brands of Acrylic IOLs. However, differences in design (not only related to the edge) significantly reduce the incidence of moderate and severe grades of dysphotopic symptoms.

Radiation induced mutagenesis followed by in vitro selection was employed for salt tolerance in popular Indian sugarcane （saccharum officinarum L.） cv. CoC-671. Embryogenic calli were gamma irradiated and exposed to different levels of NaCl （42.8, 85.6, 128.3, 171.1,213.9, 256.7, 299.5, or 342.2 mM）. The relative growth rate （RGR） decreased progressively with increasing salt stress and was the least with a salt stress of 256.7 mM （0.25±0.009）, almost 10 fold lesser than the control. The RGR was significantly lower in 85.6 mM and higher salt stressed calli than the control. The survival percent also decreased, with an increase in NaCl concentration. In case of 10 and 20 Gy irradiated calli, regeneration was observed up to 85.6 mM NaCl selection, medium, whereas, higher treatments （128.3 mM and beyond） exhibited browning initially. However, in the subsequent subcultures, regeneration was obtained in the case of 10 and 20 Gy irradiated calli on 128.3 and 171.1 mM NaCl selections. Higher dose of gamma irradiation （40 Gy） also showed regeneration, but only with 85.6 mM NaCI selection. The unirradiated calli regenerated the highest number of plantlets followed by 10 and 20 Gy irradiated calli on salt selection. A total of 147 plantlets were selected from different salt levels. The salt selected plants are being tested for their field performance.

了解土壤的理化特性和对土壤测定值与作物产量进行相关性研究的传统土壤测定系统,在肥料的经济利用方面已起了显著作用。表示养分有效性的土壤测定参数随作物产量的增加而减小;pH、土壤耕性和理化特性等基本土壤肥力参数,则随产量的增加而增大。在以保持作物高产为目的的集约栽培系统中,除要探明营养元素吸收率及在植物体内运转、分配和代谢外,还需进一步了解保持有效养分平衡的动力学,在土壤中(特别是根吸收区)的移动速率、单位时间(年)来自土壤和其它来源的有效养分数量及达到一定产量目标,作物对各种营养元素的总需要量等等。随着产量的增加,则更要注意通过良好的耕作、植保和有效的施肥措施,保证作物的健壮生长。本文着重介绍了茶树集约栽培系统中进行的典型分析。

作者： v.Rybá s.vohralik 张裕庆

前言在可控硅通断时,尤其是在电阻负载的场合下,应注意使电流上升率不超过所用大功率半导体元件的di/dt最大电流上升率。在电阻负载R通断的最不利场合下,应利用电感L来调整容许的电流上升率,如图1所示,电感与可控硅Ty串联。

浮动式平台对挠性管的疲劳损坏

国外油田工程 1999年第7期15卷 47-49页

作者： J.s.Jang v.A.Avakov 曹峰新疆准东石油勘探开发公司信息研究所

我们已经开发出一个PC计算机模型能够准确预测浮动式平台升降对挠性管劳损的作用。这个模型表明。如果操作中不正确评估和预测浮动式平台升降的作用，挠性管劳损会在几分钟或几小时内导致操作失败。
