它可以通过振动位移和激振力的相位的变化来判断转子的临界转速；当挠性转子由不平衡力引起振动时，在不同的转速下有不同的振型，根据不同的振型对转子进行有针对性的平衡；另外根据检测到的轴心轨迹图形状，可以分析出造成振动的具体原因，根据不同的原因进行防振和减振。

We prove that the Jordan semi-triple derivable maps of the algebra of all n×n matrices over a 2-torsion free commutative ring with unity is the sum of an inner derivation and A_φ, where A_φis the image of A underφapplied entrywise andφis an additive derivation over R.

This dissertation investigates the construction of pseudo-random sequences (pseudo-random numbers) from elliptic curves and mainly analyzes their cryptographic properties by using exponential sums over rational points along elliptic curves. The main results are as follows:(1) The uniform distribution of the elliptic curve linear congruential generator is discussed and the lower bound of its nonlinear complexity is given.(2) Two large families of binary sequences are constructed from elliptic curves. The well distribution measure and the correlation measure of order k of the resulting sequences are studied. The results indicate that they are "good" binary sequences which give a positive answer to a conjecture proposed by Goubin et al.(3) A kind of binary sequences from an elliptic curve and its twisted curves over a prime field F_p. The length of the sequences is 4p. The "1" and "0" occur almost the same times. The linear complexity is at least one-fourth the period.(4) The exponential sums over rational points along elliptic curves over ring Z_ are estimated and are used to estimate the well distribution measure and the correlation measure of order k of a family of binary sequences from elliptic curves over ring Z_.(5) The correlation of the elliptic curve power number generator is given. It is proved that the sequences produced by the elliptic curve quadratic generator are asymptotically uniformly distributed.(6) The uniform distribution of the elliptic curve subset sum generator is considered.(7) We apply the linear feedback shift register over elliptic curves to produce sequences with long periods. The distribution and the linear complexity of the resulting sequences are also considered.

In fact, everything has these animations: bunny rabbits scratch behind their ear, deers bow their heads and eat some grass, younger NPC's bounce impatiently or outstretch their arms as they run to pretend they are flying in an airplane, and Squirrels groom themselves.

而实际所有东西都有这类动态：小兔子挠它们的耳背，鹿弯下它们的头来吃点草，幼小的NPC会不耐烦的跳动或升长他们的手臂来扮飞机，而松鼠会清洁自己。

Results show that the Spiti shale in Zanskar terminated 15Ma later than that in southern Tibet, while the lowermost Cretaceous quartz sandstone in Zanskar appeared 18Ma later than that in southern Tibet. The age of volcanic sandstone in southern Tibet is very poorly time constraint and their deposition occurred somewhere within Berriasian～early Albian. In Thakkhola, the Chukh Group volcanic sandstone are of late Hauterivian-early Albian age (duration about 20Ma), while in Zanskar, the volcanic sandstones facies only appeared in Albian (duration of less than 10Ma). Therefore, it can be concluded that the onsets of both quartz sandstone and volcanic sandstone occurred earlier in eastern Tethys Himalayas than in western Tethys Himalayas .

侏罗纪末～白垩纪初印度大陆的北缘同时期存在大陆向上挠曲，导致陆源碎屑输入量的快速增加，石英砂岩广泛存在；早白垩世火山岩屑砂岩对应着的印度大陆北缘地层侵蚀加深，使得较深部的深成火山岩暴露并遭受侵蚀；石英砂岩和早白垩世岩屑砂岩所代表的印度大陆剥露时间在空间上的&东早西晚&，说明构造运动首先是从特提斯喜马拉雅的东部开始（大印度与澳大利亚的彻底分离），然后逐渐波及西部的，东西时间差为15～20Ma；由于地壳均衡作用，大陆分离后原先地壳挠曲转变为地壳下沉，发生强烈的构造沉降，故Albian之后沉积一套深水环境下的海绿石、磷酸盐和黑色页岩沉积。
