光点

There is normally a base specular, which is the absorbed light.

The results infer that the spatialfrequency has nothing to do with the position of spherical wave and the attribute of reference beam and object beam.

空间频率与参考光和物光的属性、球面波会聚点的位置无关。

The light saturate point and light compensate point of seedling were 1841.67nmol m-2s-1 and 155.18 mol m-2s-1 respectively, but the LSP and LCP of the young trees were 1810.00 m-2s-1 and307.07 mol m-2s-1.(3) Comparing with other three tree species, the tree of heaven had special leaf POD isozyme patterns related with the characteristic of insect-resistance.

幼苗、幼树叶片的净光合速率日变化具有两种变化曲线，均出现"午休"现象：幼苗的光饱和点与光补偿点分另伪1841.67μmol·m~(-2)·s~(-1)和155.18μmol·m~(-2)·s~(-1)；幼树的LSP与LCP分别为1810.00μmol·m~(-2)·s~(-1)与307.07μmol·m~(-2)·s~(-1)。

Some approved aneugens Trip terygiuwlIypogaucum (evelHutch, colchicine, thiabendazole, a tropine sulfate,d-ubocurarine was added into the reactive system respectively and the changes of their absorption values were taken down during different periods under the conditions of 37 0C and 350nm .

本研究通过多步聚合和解聚合反应从猪脑中分离纯化微管蛋白，建立微管蛋白的体外聚合和解聚合反应平衡体系，并将已证实的非整倍体诱发剂（昆明山海棠根部水抽提物、2-（4′-噻唑）苯丙咪唑、硫酸阿托品、d-筒箭毒碱）分别加入此反应平衡体系中，于37℃、350nm条件下，记录此体系不同时期的吸光值变化，与阳性对照物和溶剂对照处理平衡体系后的吸光值在相同时间点作比较，以此评估这几类非整倍体诱发剂对离体条件下的微管蛋白聚合的影响，寻求这几类非整倍体诱发剂是否可通过抑制微管蛋白聚合作用途径而诱发非整倍体。

And the leaf photosynthetic rate of acclimated seedlings were always higher than those of unacclimated seedlings during the different duration of low temperature stress.

结果表明：与未驯化苗相比，冷驯化苗叶片的光合速率和光补偿点下降，但光饱和点有所增大；在低温胁迫下的不同时间里，驯化苗的光合速率均高于未驯化苗。

It is difficult to be simulated and analyzed due to the excessive surfaces, complex structure and locomotory parts in zoom lens. All the transmission planes taken as the partial reflection and partial transmission planes were simulated with ASAP（advanced system analysis program）and the stray rays on "dangerous surfaces" which easily generate the ghost images in zoom lens were analyzed. Based on it, the zoom lens was optimized and the quality of image was improved by changing the curvature and refractive index of the second reflection planes.

利用ASAP软件模拟每个透射面作为部分透射、部分反射的表面，对变焦光学系统非轴上光进行分析，模拟出变焦系统的光学元件表面和光机内壁，实行实际光线追迹，然后以像面为研究对象，进一步实施实际光线追迹，模拟出全部散射光在像面上的能量分布，找出鬼像形成的原因，并在此基础上通过改变二次反射所在面的曲率或改变所在面的折射率两种方法对变焦光学系统进行优化，减小鬼点数目，以提高系统的成像质量。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
