2According to requirement of suppressing stray light in two-mirror system, vertex coordinate formulas of inner baffle are deduced based on geometrograph in the case of certain obscuration, viewing field and vignetting. In order to reduce the obscuration, conical baffle of secondary mirror is ameliorated into a shutter one. Outer baffle is designed when angle of stray light suppressing is foregone and the vanes are designed in C-language program. Finally, the same-height vanes in drawtube between primary and secondary mirrors are designed for further suppressing the stray light in two-mirror system.

According to study on UV-Vis opitical property、qualitative antibacterial experiment 、quantitative antibacterial experiment of anatase nano-TiO_2 and antibacterial powder (adulterated by Ag ion and Ce ion) we turned out that antibacterial powder's diffuse reflection spectrum obviously Einstein shift which makes it can absorb more visible-light. Not only irradiated by UV-light but also irradiated by visible-light antibacterial powder both possess photocatalytic capability, which brought new functions that improve latex's quality.

通过对锐钛型纳米二氧化钛和抗菌粉等光催化纳米材料的UV-Vis光学分析、定性抗菌试验、定量抗菌试验的研究表明，复合掺杂银、铈等稀土离子的锐钛型纳米二氧化钛，其UV-Vis漫反射光谱明显红移，大大加强了它对可见光的吸收能力，因此除了在紫外光为光源的条件下具备光催化能力，在普通光源条件下也具备光催化能力。

The light on our convention meaning is visible light, this part light is the one fraction of electromagnetic wave spectrum only.

我们常规意义上的光是可见光，这部分光只是电磁波波谱的一小部分。

Current peaks for different spins in the Ⅰ-Ⅴ curve split. The confined"light"hole energy levels of the QW turn out to be an effective tunnelling channel for both"heavy"and"light" holes. Although considerable tunnelling current originate from the"heavy"hole state in the emitter region, the current in the collector is mainly carried by the"light"hole state.

无论对重空穴还是轻空穴来说，量子阱中轻空穴的束缚能级都是有效的隧穿通道，虽然隧穿电流有相当大比例由发射极重空穴态提供，但在集电极端大部分电流又由轻空穴态传导。

When the power was 40J/cm2, the situation was similar to that with 30J/cm2 but more severe.CONCLUSION:① the blue light intensity in 30J/cm2 and 40J/cm2 could both induce the acute retinal light injury,② AcrySof one piece IOL and other PMMA IOLhave no obvious effect no retina comparing to direct eradiation,③AcrySof Natural can weaken the injury of blue light to some extent.

30J/cm2与40J/cm2蓝光光照强度均可造成新鲜离体猪视网膜的急性光损伤；Acrysof一片与直接光照相比对视网膜的光损伤形态学没有明显改变：Acrysof Natural与Acrysof一片相比具有减弱光损伤的作用。

The exterior of the product is of double-globe shape, light-transmittable shade and luminous source is closed in with round high-transparent organic glass shade, and double luminous sources are adopted; the above is a lighting main lamp and a auxiliary light-changeable lamp of cylinder shape is at the below. The entire light fixture full of modern air and practical value is the product with comparatively more favorable ratio of function and price.

本产品外型设计采用双圆形灯具造形，透光罩和光源用高透明度有机玻璃园罩封闭，并采用了双光源系统；一只照明主灯在上，一只变光圆柱副灯在下，当天黑后主副灯同时开始工作，深夜副灯关闭，主灯工作至天亮自动关闭，整个灯具极具现代气派和实用价值，是目前太阳能灯具中有较高性能/价格比的产品。

In the course of the calendering, pressure bearing steel strip temperature is too high, the local Polish film flacherie it appropriate to reduce the pressure of the pressure and temperature light; or possibly finish and calendering technology conditions do not match the business card printing and membership card making products for layer on the surface cools, the same as the above band of light, laymch avulsing is poor technical condition so that it matches on, reducing the calender speed, to improve the optical layer on the light that is between the avulsing: same as above.

温度偏高，使制卡和会员卡制作品在压光过程中脱水过多，含水量降低，因而纸张纤维变脆，应降低压光的工作温度，并采取有效措施，保持制卡和会员卡制作品中—定的含水量；压光中压力过大，使制卡和会员卡制作品的延伸性和可塑性降低，韧性变性，可减少压光中的压力；若因为上光油的后加工适性不良，则应重新选择加工适性较好的上光油；后加工工艺条件选样不合适，可调整后加工工艺条件，使其与制卡和会员卡制作品压光后的适性相匹配。

The spectral features of apple florescence mainly presented as absorption of blue light and red light, reflection of green light, and the strong reflection of near-infrared between 750 nm to 1300 nm.

C Thermally controllable light valves:As described above, the clearing temperature of PDCLCs can be increased by UV-curing because of the reduction of impurity concentration. Therefore, when the texture of a CLC cell in the UV-cured region are changed to focal conic one, the scattering of light from the sample is maximum. However, the clearing temperature of PDCLCs can be increased continually with continually irradiating with UV light onto the sample, but the scattering is unchanged.

当PDCLC照射紫外光的时间超过某一特定时间，则表面配向被聚合物薄膜破坏而达成散射态之穿透度最低状态，若持续照光聚合时，因仍然处於focal conic态，故穿透度不再改变，但单体聚合造成相变温度上升，直到单体全部聚合为止。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.
