Comparison was made between the biological classification system for soil borne plant parasitic nematodes of the Tylenchina suborder and with a nonbiological one (Chinese Soil Taxonomy as an example) in biodiversity characteristics by calculating the power law distribution and Lognormal distribution of the two systems to analyze their similarities and differences.

本文通过计算两种系统分类的幂律和对数正态分布，对土壤植物寄生的线虫类分类体系和非生物系统分类的多样性特征进行了比较，进而分析它们之间的相似性和差异性。

Results show that nonspiral plate may adjust the optical intensity distribution in focal region considerably, so we can alter and control the optical intensity distribution in fbcal region by changing the vary rate of phase variation. This technique can be used to carry particles in optical tweezers system

数值模拟结果表明：通过调节相位片的相应变化率，可能方便地调节焦点区域光强分布，因此可通过调节相位片的相位变化来控制和改变焦点区域光强分布，这种技术方法可应用于光钳系统中控制搬运微小颗粒。

At the same time, the distribution mode of the strand shallow lake and the delta deposition system have been established in this region. The research on type and distribution regulation of subtle trap combining with geologic strata structure indicates that the south slope belt, ditch valley belt, Guangbei slope break and southwest of noselike conformation belt are the more advantageous belt to find subtle trap.

在层序地层格架内，通过古地貌研究和沉积体系研究，识别出低位沟谷带和坡折带等控制沉积的两种地貌，建立了本区滨浅湖沉积体系和三角洲沉积体系的分布模式，结合地层结构特点，对隐蔽圈闭类型及分布规律进行研究，指出南部斜坡带、沟谷带、广北坡折带及鼻状构造带西南端是寻找隐蔽圈闭的有利区带。

The water chamber takes the shape of tilting cube, in favor of uniform distribution of cooling water on tube plate surface. The tube bundle is divided into two groups of zygomorphy according to the bisection system and it has eight support clapboards. The siphonopore center of each clapboard increases a certain distance corresponding to that of two tube plates and the cooling tube takes the shape of arch. The two-way cooling water of bisection flows through the condenser in opposite direction so as to improve the distribution of heat load for tube bundle. Around the throat of condenser, the final stage low-pressure heater, air extraction tube, intake device of bypass exhaust and the like are deployed.
