生长曲线

The recent advances in the studies of phototropism are reviewed in this paper:more and more evidences support Bruinsma-Hasagawa hypothesis that tissues within the plant are affected by the Pfr gradient and express growth redistribution; Fluence-response studies of phototropism indicate that fPIPP and TDP are general types of multiple response types of phototropism; several photoreceptors involving phototropism have been characterized; four genetic loci affecting phototropism have been identified by mutants of Arabidopsis thaliana .

本文综述近年来植物向光反应研究方面的进展：（1）植物内部组织感受Pfr梯度引起生长再分布，越来越多的证据支持Bruinsma-Hasagawa假说；（2）光强-反应曲线的研究表明，向光反应存在多种反应类型，其中第一次正向光弯曲和第二次正向光弯曲最为普遍；（3）已鉴定了几种参与向光反应的光受体；（4）通过拟南芥突变体的研究确定了影响向光反应的4个基因。

The model of programmed crystallization of SPM was proposed based on the moment transformation of the population considering the agglomeration. The optimal temperature-time curves in a batch crystallizer which maximized the terminal mean size and mean weight size can be determined from the application of the Pontryagin Maximum Principle. The calculated crystallization results heating under optimal temperature were compared with ones under linear or natural heating temperature.

The aim of this study was to reveal the adaptation response of limestone plants to light and water. The light response curves of limestone plants Alchornea trewioides, Bauhinia championii, Pteroceltis tatarinowii, Sapium rotundi folium were measured with Licor-6400 Photosynthesis Analyzer in Karst area, and parameters of photosynthesis were simulated by non-rectangle hyperbolae function.

为阐明石山植物对光与水分的适应能力，采用Li-6400光合作用测定系统，对岩溶区石山植物红背山麻杆、九龙藤、青檀和圆叶乌柏生长盛期的光响应曲线进行了测定，并利用非直角双曲线模型对4种植物光合作用生理参数进行拟合。

Meanwhile, result comes out that seven fossil samples are mostly evergreen Araucarioxylon, deciduous species prapably exists, but their fixed numbers of growing year are extraordinarily variant; Analysis of ariance indicates that, imposing ray cells, radial tracheid diameters-, the ratios of ray cells to radial tracheid diameters on distinguishing seven samples is doable as a whole, while not fitting for individuals.

经方差分析可以看出，利用射线直径、管胞直径和射线管胞比可以在总体上区分各标本，但对个别样本不适用；射线高度这一性状在各标本间差别很小，不能区分；结果认为：标本2和标本6的性状最相近，为相同的种类；标本1、4、7可能为同一属；对方差和CSDM曲线的综合分析认为，标本1、3、6的生长年限存在一定的区别，可能导致在方差分析上出现些许误差。
