光电计时器是一种研究物体运动情况的常见仪器．当有物体从光电门通过时，光电计时器就可以显示物体的挡光时间．现利用如图甲所示装置探究物体的加速度与合外力、质量关系，其 NQ是水平桌面，PQ是一端带有滑轮的长木板，1、2是固定在木板上的两个光电门（与之连接的两个光电计时器没有画出）．小车上固定着用于挡光的窄片K，测得其宽度为d，让小车从木板的顶端滑下，光电门各自连接的计时器显示窄片K的挡光时间分别为t₁和t₂．

（1）该实验中，在改变小车的质量M或沙桶的总质量m时，保持M＞＞m，这样做的目的是______；

（2）为了计算出小车的加速度，除了测量d、t₁和t₂之外，还需要测量______，若上述测量量用x表示，则用这些物理量计算加速度的表达式为a=______；

（3）某位同学经过测量、计算得到如下表数据，请在图乙中作出小车加速度与所受合外力的关系图象．

组别	1	2	3	4	5	6	7
M/kg	0.58	0.58	0.58	0.58	0.58	0.58	0.58
F/N	0.10	0.15	0.20	0.25	0.30	0.35	0.40
a/m•s-2	0.13	0.17	0.26	0.34	0.43	0.51	0.59

（4）由图象可以看出，该实验存在着较大的误差，产生误差的主要原因是：

甲公司与乙公司协议合作开发某产品的生产新技术，共享利益。但当乙公司主张申请专利时，甲认为技术还不成熟，一旦公开将丧失其秘密性，故不同意申请。乙公司见此状况遂独自申报专利，但被专利局驳回。后乙公司与甲公司几经协商，甲公司声明放弃其共有的专利申请权。乙公司再次向专利局申报专利，获得了批准。
乙公司与丙公司签订专利实施许可合同，约定将该专利由丙公司独家实施，丙公司支付使用费。3个月后，丙公司拒绝向乙公司支付使用费，理由是甲公司也在使用该专利技术。后经调查，丙公司将该专利技术秘密许可丁公司使用。
根据上述事实，分析下列问题：

在甲公司不同意申请专利的情况下，乙公司能否独自申请专利权
