As we known, common Loran - C receiver employs a fixed da- tum - mark in order to avoid interference caused by skywave, as the SNR is often poor at this point due to the amplitude limit of the pulse envelope, so it greatly increases time for tracking the datum - mark.

常规接收机为了防止天波干扰，将基准点设置在一个固定位置上，导致基准点处信噪比受包络限制而较低，从而大大增加了对准基准点的时间。

The luminescence intensity of suspended immune cells (1×10〓 cells/ml) from peripheral blood, anterior kidney and spleen of grass carp, which were from two groups immunized with being injected Aeromonas hydrophilia and unimmunized respectively, were detected by means of BPCL4 Intelligentized Ultraweak Luminometer, the datum that were dealt with statistics demonstrated that luminescence intensity of the cells from all kinds of immune organs and blood were intensified after the fish were immunized in two weeks and the luminescence intensity from anterior kidney cells was the highest, mitogens had the enhancing effects. Luminol could strengthened luminescence intensity.

把未免疫的和经过嗜水产气单胞菌注射免疫的草鱼外周血、前肾、胸腺和脾脏以及它们的悬浮细胞（密度控制在1×10〓个细胞／ml左右）分别用BPCL4智能化微弱发光测量仪测量各组的发光强度，结果显示：草鱼各类免疫器官与细胞在免疫两周后发光强度增加，肾细胞的发光强度最大；有丝分裂原具有增强作用；化合物鲁米诺能提高发光强度。

First, experimental datum is analyzed and it is found that the shallow water ocean internal wave spectrum is different from that of the deep ocean GM spectrum. Then, the theory of weak turbulence is systematically summarized, and Lvov and Tabak's method of obtaining the deep ocean internal wave spectrum is introduced. They applied the theory of weak turbulence to internal waves of long wave length and found that GM spectrum maybe obtained theoretically.
